We explore one systematic review and meta-analysis of both observational and randomized studies examining COVID-19 vaccines in 5- to 11-year-olds, which reported substantial benefits associated with vaccinating this age group. We discuss the limitations of the individual studies that were used to estimate vaccination benefits. The review included five observational studies that evaluated vaccine effectiveness (VE) against COVID-19 severe disease or hospitalization. All five studies failed to adequately assess differences in underlying health between vaccination groups. In terms of vaccination harms, looking only at the randomized studies, a significantly higher odds of adverse events was identified among the vaccinated compared with the unvaccinated. Observational studies are at risk of overestimating the effectiveness of vaccines against severe disease if healthy vaccinee bias is present. Falsification endpoints can provide valuable information about underlying healthy vaccinee bias. Studies that have not adequately ruled out bias due to better health among the vaccinated or more vaccinated should be viewed as unreliable for estimating the VE of COVID-19 vaccination against severe disease and mortality. Existing systematic reviews that include observational studies of the COVID-19 vaccine in children may have overstated or falsely inferred vaccine benefits due to unidentified or undisclosed healthy vaccinee bias.

INTRODUCTION: Optimal venous thromboembolism (VTE) enoxaparin prophylaxis dosing remains elusive. Weight-based (WB) dosing safely increases anti-factor Xa levels without the need for routine monitoring but it is unclear if it leads to lower VTE risk. We hypothesized that WB dosing would decrease VTE risk compared with standard fixed dosing (SFD). METHODS: Patients from the prospective, observational CLOTT-1 registry receiving prophylactic enoxaparin (n=5539) were categorized as WB (0.45-0.55 mg/kg two times per day) or SFD (30 mg two times per day, 40 mg once a day). Multivariate logistic regression was used to generate a predicted probability of VTE for WB and SFD patients. RESULTS: Of 4360 patients analyzed, 1065 (24.4%) were WB and 3295 (75.6%) were SFD. WB patients were younger, female, more severely injured, and underwent major operation or major venous repair at a higher rate than individuals in the SFD group. Obesity was more common among the SFD group. Unadjusted VTE rates were comparable (WB 3.1% vs. SFD 3.9%; p=0.221). Early prophylaxis was associated with lower VTE rate (1.4% vs. 5.0%; p=0.001) and deep vein thrombosis (0.9% vs. 4.4%; p

Background: Frailty often requires intensive care, and the admission outcomes of frail patients are often poor. However, owing to the lack of reliable diagnostic indicators, quickly identifying frailty is challenging. The present study aimed to explore the associations of the platelet/high-density lipoprotein cholesterol ratio (PHR; a novel inflammatory indicator) with frailty and all-cause mortality. Methods: The present study analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018. Frailty was assessed on the basis of the 49-item Frailty Index. The associations of the PHR with frailty and long-term survival prognosis were explored through weighted logistic regression, weighted restricted cubic spline (RCS), and weighted Cox regression, with adjustments for demographic factors, lifestyle, blood lipids, medication history, and complications. In addition, subgroup and interaction analyses were conducted. Finally, several sensitivity analyses were performed. Results: A total of 15,615 adult participants were included, with 7,928 women (53.63%) and an average age of 60.76 years. After fully adjusting for confounding variables, the prevalence of frailty in the highest PHR quartile group of was significantly greater than that in the lowest quartile group (OR: 1.23, 95% CI: 1.04–1.47; P = 0.02). The RCS showed that the inflection point was 166.7. Before and after the inflection point, the PHR was negatively associated (OR: 0.88, 95% CI: 0.80–0.97, P = 0.01) and positively associated (OR: 1.10, 95% CI: 1.02–1.19, P = 0.01) with frailty, respectively. Subgroup analysis suggested that the association between PHR and frailty was stronger in women than in men. A total of 5,544 frail participants were included in the survival analysis. The RCS revealed that the PHR was associated with the all-cause mortality risk of frail participants in a U-shaped manner, with an inflection point of 240.4. Before and after the inflection point, the PHR decreased (HR: 0.89, 95% CI: 0.81–0.97, P = 0.01) and the all-cause mortality risk increased (HR: 1.08, 95% CI: 1.02–1.14, P = 0.01), respectively. Conclusion: The present study suggests that there is a J-shaped association between PHR and frailty in the adult population of the United States and that the association between the PHR and frailty is stronger in women. In addition, the PHR has a U-shaped relationship with the all-cause mortality risk of frail patients. [ABSTRACT FROM AUTHOR]

Background: Malnutrition is a complication of chronic kidney disease (CKD). Whether malnutrition, assessed via the geriatric nutritional risk index (GNRI), is associated with the incidence and risk of CKD in older individuals remains unclear. Methods: Data from the National Health and Nutrition Examination Survey and the UK Biobank database were used. Older participants over 60 years old with available data for GNRI assessment and CKD diagnosis were enrolled. Logistic regression models and Cox regression models were used to assess associations between the geriatric nutritional risk index and the risk of and mortality associated with CKD. Results: This study enrolled 13,162 participants from the NHANES and 66,326 participants from the UK Biobank. We identified 6,135 and 16,662 CKD patients in the NHANES and UK Biobank, respectively, with the majority being male (74% in the NHANES and 52% in the UK Biobank). The average age of CKD patients was 72.3 (SD 7.2) years in the NHANES and 64.9 (SD 2.9) years in the UK Biobank. The median follow-up times of older CKD patients were 81 months and 162 months in the NHANES and UK Biobank, respectively. According to the cross-sectional analysis, individuals with a lower GNRI had an increased likelihood of having CKD, with odds ratios of 1.38 (95% CI: 1.05–1.80, P = 0.020) in the NHANES and 2.35 (95% CI: 1.89–2.92, P < 0.001) in the UK Biobank. According to our analysis of the risk of incident CKD in the UK Biobank, a lower GNRI was associated with a greater incidence of CKD (HR: 1.11, 95% CI: 1.04–1.18; P = 0.002). According to the analysis of the risk of mortality, a lower GNRI was associated with an increased risk of death among older CKD patients (NHANES: HR: 1.69, 95% CI: 1.13–2.53, P = 0.011; UK Biobank: HR: 2.28, 95% CI: 1.94–2.69, P < 0.001). Conclusion: Malnutrition assessed by the GNRI was significantly and independently associated with the incidence of CKD. Moreover, CKD patients with malnutrition also have a high risk of mortality.

Background: Musculoskeletal alterations causing reduced range of motion of the ankle joint are common in children with cerebral palsy (CP). Objective measurements of passive joint resistance and three-dimensional skeletal muscle volume and muscle architecture can lead to a comprehensive understanding of which factors influence joint range of motion. Research question: To investigate the relation between the passive dorsiflexion of the ankle joint, biomechanical contributing factors to the passive joint resistance, and muscular architectural properties of the triceps surae muscle in children with CP. Methods: In this cross-sectional observational study, 14 children with spastic CP (bilateral: 5, unilateral: 9, Gross Motor Function Classification System (GMFCS) level I:11, II:3) naïve to intramuscular tone reducing treatment, and 14 TD children were included. The passive dorsiflexion of the ankle was measured with a goniometer. Passive joint resistance and related parameters were estimated based on a biomechanical model and measurements using a motorized device, the Neuroflexor. Three-dimensional muscle architecture was quantified with diffusion tensor magnetic resonance imaging (DT-MRI). Results: In the CP group, the median [min, max] passive dorsiflexion was decreased in the most affected leg (MAL) compared to the less affected leg (LAL) (2.5° [-25°, 20°] vs. 12.5° [5°, 30°], p = 0.001). The stiffness coefficient (Nm/rad) in the MAL was significantly higher in children with CP compared to TD children (7.10 [3.39, 62.00] vs. 2.82 [1.24, 10.46], p = 0.015). Muscle architecture properties did not differ between CP and TD, except for pennation angle in the medial gastrocnemius (MG) of the MAL (CP 17.64° (2.29) vs. TD 21.46° (3.20), p = 0.017). The stiffness coefficient, in the MAL, correlated negatively to passive dorsiflexion (rs=-0.638) and pennation angle in medial gastrocnemius (rs=-0.964), and the non-linear coefficient (Non-linear 1) correlated negatively to the fascicle length of the medial gastrocnemius (rs=-0.857). Conclusion: This study shows that stiffness of the plantarflexors is related to decreased passive dorsiflexion of the ankle and muscle structure of the MG in high-functioning children with spastic CP. Assessments of how dynamic components as well as microscopic muscle alterations contribute to joint stiffness in the plantarflexors in individuals with CP are warranted. Trial registration: Retrospectively registered in ClinicalTrials.gov, NCT05447299. Observational study. Study start: 2019-01-15, register date: 2022-07-01. [ABSTRACT FROM AUTHOR]

Background: Adverse pregnancy outcomes have reached epidemic proportions in recent years with serious health ramifications, especially for diverse cancers risk. Therefore, we carried out an umbrella review to systematically evaluate the validity and strength of the data and the extent of potential biases of the established association between adverse pregnancy outcomes and cancers risk in both mother and offspring. Methods: PubMed, Embase, and Web of Science databases were searched from inception until 18 January 2024. Meta-analyses of observational studies investigating the relationship between adverse pregnancy outcomes and multiple cancers risk in both mother and offspring were included. Evidence certainty was assessed using Grading of Recommendations, Assessment, Development, and Evaluation. The protocol for this umbrella review was prospectively registered in PROSPERO (CRD42023470544). Results: The search identified 129 meta-analyses of observational studies and 42 types of cancer. Moderate certainty of evidence, exhibiting statistical significance, has been observed linking per kilogram increase in birth weight to a heightened risk of breast cancer (OR = 1.07, 95% CI = 1.02–1.12), prostate cancer (OR = 1.02, 95% CI = 1.00–1.05), leukemia (OR = 1.18, 95% CI = 1.13–1.23), and acute lymphoblastic leukemia in offspring (OR = 1.18, 95% CI = 1.12–1.23); rubella infection during pregnancy to an increased risk of leukemia in offspring (OR = 2.79, 95% CI = 1.16–6.71); and a linear dose–response association between an increase in the proportion of optimal birth weight and an elevated risk of acute lymphoblastic leukemia in offspring (OR = 1.16, 95% CI = 1.09–1.24), respectively. Conclusions: Although some adverse pregnancy outcomes have clinically promising associations with risk of several cancers in both mother and offspring, it is essential to conduct additional research to solidify the evidence, evaluate causality, and ascertain clinical utility.

Background: The procedures used to assess the methodological quality and risk of bias (RoB) of systematic reviews of observational dental studies have not been investigated. The purpose of this research was to examine the way that authors of systematic reviews of epidemiological observational studies published in dentistry conducted the methodological assessment of those primary studies. In the present article, we aimed to assess the characteristics and the level of reporting of tools used to assess the methodologies of these reviews. Methods: We searched Scopus and the Web of Science from their inceptions to June 2023 for systematic reviews with meta-analyses of observational studies published in dentistry. Document selection and data extraction were performed in duplicate and independently by two authors. In a random sample of 10% of the systematic reviews, there was an agreement of more than 80% between the reviewers; data selection and extraction were conducted in the remaining 90% of the sample by one author. Data on the article and systematic review characteristics were extracted and recorded for descriptive reporting. Results: The search in the two databases resulted in the inclusion of 3,214 potential documents. After the elimination of duplicates and the application of the eligibility criteria, a total of 399 systematic reviews were identified and included. A total of 368 systematic reviews reported a methodological tool, of which 102 used the Newcastle–Ottawa scale. Additionally, 76 systematic reviews stated the use of a modified methodological tool. Information about the approach of assessing the methodological quality or RoB of primary studies but reporting no tool or tool name occurred in 25 reviews. Conclusions: The majority of authors of systematic reviews of epidemiological observational studies published in dentistry reported the tools used to assess the methodological quality or RoB of the included primary studies. Modifying existing tools to meet the individual characteristics of various studies should be considered. [ABSTRACT FROM AUTHOR]

Background: While traditional medicine (TM) is employed by a significant portion of the global population for managing health issues, clinical guidelines and state recommendations often overlook this practice. The aim of this study was to describe the frequency of use of TM to control 3 metabolic risk factors (MRF): hypertension, hypercholesterolemia, and hyperglycaemia; and the sociodemographic, economic, and clinical characteristics associated with the use of TM. Methods: Cross-sectional descriptive study that analyses data obtained from a representative population survey in 2 health districts, one urban in the south of Quito and another in a forested rural area with diverse ethnic groups in Esmeraldas, Ecuador. We include 602 individuals with at least one MRF. We calculated the proportion of people reporting the regular use of TM (herbal or traditional remedy) to control their MRF and we assessed potential associations with sociodemographic, economic, and clinical characteristics with a multivariable logistic regression model. Results: In two very different sociocultural contexts in Ecuador we found that use of TM to control MRF was frequent (39.4% in Esmeraldas, 31.1% in Quito), frequently in combination with CM. There is a notable percentage of people, 33.9% in Esmeraldas and 39.0% in Quito, who did not take any treatment for their MRF, and the remainder used CM alone. In both settings, an individual's education lever was significantly associated with TM use. Whereas in Quito individuals with higher education more frequently treated their MRF with TM (aOR 2.04, 95% CI 1.03–3.90), in the rural, hard-to-reach context of Esmeraldas, it was more frequent among people with no formal schooling (aOR: 3.76; 95%CI 1.59–8.88), as well as those of younger age (aOR by year: 0.97; 95% CI 0.95–0.99) and afro ethnicity (aOR: 2.13; 95%CI 1.02–4.45). Conclusion: Traditional medicine is used by a significant proportion of the population in Ecuador, highlighting the need for a more accessible and intercultural healthcare approach. The health system should ensure access to the necessary information and resources for the management of their metabolic risk factors. [ABSTRACT FROM AUTHOR]

Objective: To clarify the causal relationship between anxiety-depression and the progression and outcomes of vitiligo, providing a basis for enhancing psychological interventions in the treatment of vitiligo. Methods: A two-sample Mendelian randomization analysis was used to validate the causal relationship between anxiety, depression, and vitiligo. The Hospital Anxiety and Depression Scale (HADS) assessed the psychiatric condition of vitiligo patients. Fisher's chi-square tests and rank sum tests analyzed the differences in clinical characteristics among vitiligo patients with different HADS scores. Regression analysis assessed the correlation between anxiety-depression and disease progression and treatment outcomes. Results: Mendelian randomization analysis showed that depression significantly increases the risk of vitiligo (OR = 4.46, 95% CI: 1.16-17.18, p = 0.03). According to the HADS scores, clinical characteristics differed significantly among the groups (p < 0.05). Univariate regression analysis demonstrated that both HADS (B = -1.168, p < 0.001, 95% CI: -1.532 to -0.804) and VIDA (B = -2.157, p < 0.001, 95% CI: -3.464 to -0.887) were significantly negative associated factors for disease outcomes. However, HADS (B = -1.006, p < 0.001, 95% CI: -1.475 to -0.657) emerged as the only factor influencing therapeutic efficacy in multivariate regression analysis. A restricted cubic spline graph illustrates a U-shaped relationship between HADS and clinical efficacy, with the most significant impact on therapeutic efficacy occurring when HADS equals 15. Conclusion: Anxiety--depression exhibit a bidirectional positive causal relationship with vitiligo. Moderate to severe anxiety-depression significantly influences the clinical efficacy of vitiligo treatment. [ABSTRACT FROM AUTHOR]

Background/Objectives: Patients with Non-Alcoholic Fatty Liver Disease (NAFLD) are reported to have an increased risk of developing severe infections, leading to hospitalizations with sepsis. However, data regarding the impact of comorbid NAFLD on in-hospital outcomes of patients with sepsis is scarce. Methods: This nationwide retrospective observational study using discharge data from the National Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP), and Agency for Healthcare Research and Quality included 21,057,911 adult patients who were admitted to hospitals in the United States between 2000 and 2019 with a primary discharge diagnosis of sepsis. These patients were categorized according to the presence or absence of comorbid NAFLD. The twenty-year trend of nationwide NAFLD prevalence among sepsis inpatients was elucidated. Multivariable logistic regression analysis was used to analyze NAFLD's impact on sepsis outcomes. Results: In the twenty-year study period, the prevalence of NALFD among sepsis inpatients trended up from 1.2% in 2000 to 4.2% in 2019. Similar trends were observed in regional analysis. While overall sepsis mortality decreased, comorbid NAFLD in sepsis patients was consistently associated with a higher adjusted in-hospital all-cause mortality rate (adjusted odds ratio (OR), 1.19; 95% confidence interval (CI), 1.07–1.32), higher odds of developing septic shock, and higher likelihood of development of multi–organ dysfunction. Conclusions: Comorbid NAFLD in the stage of NASH or cirrhosis is associated with higher in-hospital all-cause mortality and worse clinical outcomes in sepsis inpatients. Addressing this rising epidemic will be of paramount importance to improve sepsis in-hospital outcomes. [ABSTRACT FROM AUTHOR]

Background: Neck reflex points (NRPs) are 2 × 6 potentially tender areas of the neck, denominated NRP-C0 to NRP-C7. They are different from muscular trigger points and become tender in response to chronic trigeminal irritation. NRP examination has a high inter-rater reproducibility. We investigated the prevalence of NRPs in two populations to investigate their usefulness as a clinical test for trigeminal irritation. Methods: In total, 165 patients with chronic pain and 431 students were examined for NRP tenderness using a three-level pain scale: absent pain (PI = 0), mild tenderness (PI = 1), or marked tenderness (PI = 2). Results: In patients, we found more tender NRPs than in the student group (p < 0.001), and on the left side, more tender NRPs were found in NRP-C0–C4. Left and right NRPs appeared independently (kappa 0.1–0.4), except for NRP-C7 (kappa 0.55). Females had more tender NRPs (p < 0.001). Tenderness was independent of age, BMI, and pre-existing diseases. Conclusions: NRP tenderness occurs more frequently in patients than in students, independent from potential covariates. Our results, together with previous findings, support the use of NRP examination as a clinical test for chronic silent inflammation of the trigeminal region. These data provide a base for further studies investigating correlations of NRPs with clinical findings. [ABSTRACT FROM AUTHOR]

Background: Abnormal lipid metabolism is linked to intervertebral disc degeneration (IVDD), sciatica, and low back pain (LBP), but it remains unclear whether targeted interventions can prevent these issues. This study investigated the causal effects of lipid-lowering drug use on IVDD, sciatica, and LBP development. Methods: Single-nucleotide polymorphisms (SNPs) linked to total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-C), and non-high-density-lipoprotein cholesterol (non-HDL-C) were obtained from the Global Lipids Genetics Consortium's genome-wide association study (GWAS). Genes near HMGCR, PCSK9, and NPC1L1 were selected to represent therapeutic inhibition targets. Using Mendelian randomization (MR) focusing on these drug targets, we identified causal effects of PCSK9, HMGCR, and NPC1L1 on the risk of developing IVDD, sciatica, and LBP, with coronary heart disease risk serving as a positive control. Using summary data from Mendelian randomization (SMR) analysis, we evaluated potential therapeutic targets for IVDD, sciatica, and LBP through protein quantitative trait loci (pQTL). The genetic associations with IVDD, sciatica, LBP, and coronary heart disease were derived from FinnGen (discovery) and UK Biobank (replication). Additionally, a cross-sectional observational study was performed using data from the National Health and Nutrition Examination Survey (NHANES) to further investigate the connection between LBP and statin use, with a sample size of 4343 participants. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated to assess the outcomes. Results: The NHANES-based cross-sectional study indicated that non-statin use was associated with an increased risk of developing LBP (OR = 1.29, 95% CI [1.04, 1.59], P = 0.019). Moreover, Inverse-variance weighting (IVW) analysis revealed that NPC1L1-mediated reductions in TC, LDL-C, and non-HDL-C concentrations were associated with a decreased risk of developing IVDD (P = 9.956E-03; P = 3.516E-02; P = 1.253E-04). Similarly, PCSK9-mediated reductions in LDL-C and TC concentrations were linked to a lower risk of developing sciatica (P = 3.825E-02; P = 2.709E-02). Sensitivity analysis confirmed the stability and reliability of the MR results. MST1 (macrophage stimulating 1) levels was inversely associated with IVDD, sciatica, and LBP risks. Conclusion: The results of cross-sectional study suggested that non-use of statins was positively correlated with LBP. The results of Mendelian randomization study suggest that NPC1L1 could lower the risk of developing IVDD by reducing TC, LDL-C, and non-HDL-C levels. Additionally, PCSK9 may reduce the risk of developing sciatica by lowering LDL-C and TC levels. In contrast, HMGCR appears to have no significant effect on IVDD, sciatica, or LBP development. Nonetheless, further research is needed to verify these preliminary results. MST1 warrants further exploration as a potential therapeutic target. It is necessary to do further research to validate these findings. [ABSTRACT FROM AUTHOR]

Aims Methods Results Conclusions Hospitalizations for adverse drug reactions (ADR‐HA) have increased over the last decade, but the impact of ADR‐HA has rarely been evaluated. The aim of this study was to estimate the economic burden of ADR‐HA in France.A partial economic evaluation from the viewpoint of French public health insurance was performed, based on a previous pharmacovigilance study (IATROSTAT) performed in 2018 in public hospital medical units. The cost included direct medical costs, collected retrospectively, from the French hospital discharge database. The economic burden was estimated by calculating the total cost per ADR‐HA patient (cost of hospital stays, additional daily cost of specific stays, such as in a resuscitation, intensive care or continuous surveillance unit, drug products and medical devices in addition to Healthcare Resource Group‐based tariffs, and specific outpatient consultations and other clinical and technical medical procedures, over 3 months as from the first day of ADR‐HA). The robustness of the results was assessed using a one‐way deterministic sensitivity analysis of cost factors applying tariffs from 2023 instead of 2018.According to the 2018 tariffs (vs. 2023), the mean total cost per patient with ADR‐HA was estimated at €5208 ± €3719 (vs. €5974 ± €4232) ranging from €514 to €23 355 (vs. €618 to €27 380). The total cost for 196 patients with ADR‐HA admitted to a sample of French public hospitals was estimated at €1 020 549 (vs. €1 170 960). It could be estimated at €1.3 billion at the national level.In addition to the increase in the number of expensive drugs, the ageing population and polypharmacy, the economic impact of serious ADR‐HA weighs heavily on healthcare spending.

Pharmacists' job performance is crucial for improving pharmacy services. The purpose of this study was to evaluate the association of emotional intelligence with the job performance of pharmacists in Saudi Arabia. Using social media platforms, we disseminated an online questionnaire to pharmacists licensed to practice in Saudi Arabia between June and July 2022. The questionnaire was filled out by 352 pharmacists. The majority of the participants were women (60.5%) and working as community pharmacists (55.7%). On self-reported emotional intelligence and job performance scales, the respondents scored an average of 5.5 ± 0.9 (out of 7) and 4.0 ± 0.6 (out of 5), respectively. Multiple linear regression analyses revealed that emotional intelligence had a significant relationship with job performance (β = 0.43, p < 0.001). In conclusion, the findings indicated that emotional intelligence may influence the job performance of pharmacists in Saudi Arabia. As the primary objective of every organization is to accomplish the best possible performance, prioritizing emotional intelligence is important. Further research is needed to identify the impact of emotional intelligence on work performance, which could potentially enhance clinical outcomes for patients. [ABSTRACT FROM AUTHOR]

Background: It remains unknown whether composite-dietary-antioxidant-index (CDAI) is associated with the risk of sarcopenia. This study investigated the association of CDAI with sarcopenia risk among general US adults. Methods: A total of 10,093 participants were enrolled in the National Health and Nutrition Examination Surveys (NHANES) from 6 survey cycles (2003-2004, 2005-2006, 2011-2012, 2013-2014, 2015-2016 and 2017-2018). Multivariate logistic regression was carried out to examine the relationship between CDAI and the risk of sarcopenia. Restricted cubic spline (RCS) curves were employed to analyze nonlinear relationships. Results: In a multi-variable logistic regression model adjusting for demographics, lifestyle, economic status and other dietary factors, higher CDAI score was related to a lower risk of sarcopenia among US adults. Compared the highest quartile of CDAI score with the lowest, the OR and 95%CI were 0.49 (0.31-0.75). Furthermore, the RCS demonstrated a linear dose-response relationship between CDAI and sarcopenia (Pnon-linearity=0.92). These results remained consistent across subgroups stratified by age, sex, physical activity, drinking status, body mass index (BMI), smoking habits, energy intake, and Healthy Eating Index (HEI) score. In addition, the favorable associations of CDAI were primarily attributed to Vitamin E intake. Conclusion: A higher CDAI score was associated with a lower risk of sarcopenia. According to these results, a greater adherence to CDAI may benefit sarcopenia prevention in adults. [ABSTRACT FROM AUTHOR]

Objectives: The metabolic syndrome in patients with schizophrenia has consistently been a challenge for clinicians. Previous studies indicate that individuals with schizophrenia are highly prone to developing type 2 diabetes mellitus (T2DM). In recent years, a continuous stream of new observational studies has been reported, emphasizing the pressing need for clinicians to gain a more precise understanding of the association between schizophrenia and T2DM. The objective of this meta-analysis is to integrate new observational studies and further explore the potential link between schizophrenia and the risk of T2DM. Methods: We conducted a comprehensive search of PubMed, Cochrane Library, Embase, and Web of Science using medical subject headings (MeSH) and relevant keywords. The risk of bias in cohort studies and case-control studies was assessed using the Newcastle-Ottawa Scale (NOS), while cross-sectional studies were evaluated using the Agency for Healthcare Research and Quality scale (AHRQ), scoring was based on the content of the original studies. A fixedeffects model was employed if P > 0.1 and I2 ≤ 50%, indicating low heterogeneity. Conversely, a random-effects model was utilized if I2 > 50%, indicating substantial heterogeneity. Publication bias was assessed using funnel plots and Egger's test. Statistical analyses were carried out using Stata statistical software version 14.0. Results: This meta-analysis comprised 32 observational studies, involving a total of 2,007,168 patients with schizophrenia and 35,883,980 without schizophrenia, published from 2004 to 2023. The pooled analysis revealed a significant association between a history of schizophrenia and an increased risk of T2DM (Odds Ratio [OR] = 2.15; 95% Confidence Interval [CI]: 1.83--2.52; I2 = 98.9%, P < 0.001). Stratified by gender, females with schizophrenia (OR = 2.12; 95% CI: 1.70- 2.64; I2 = 90.7%, P < 0.001) had a significantly higher risk of T2DM than males (OR = 1.68; 95% CI: 1.39-2.04; I2 = 91.3%, P < 0.001). Regarding WHO regions, EURO (OR = 2.73; 95% CI: 2.23-3.35; I2 = 97.5%, P < 0.001) exhibited a significantly higher risk of T2DM compared to WPRO (OR = 1.72; 95% CI: 1.32-2.23; I2 = 95.2%, P < 0.001) and AMRO (OR = 1.82; 95% CI: 1.40-2.37; I2 = 99.1%, P < 0.001). In terms of follow-up years, the >20 years subgroup (OR = 3.17; 95% CI: 1.24- 8.11; I2 = 99.4%, P < 0.001) showed a significantly higher risk of T2DM than the 10-20 years group (OR = 2.26; 95% CI: 1.76-2.90; I2 = 98.6%, P < 0.001) and <10 years group (OR = 1.68; 95% CI: 1.30-2.19; I2 = 95.4%, P < 0.001). Conclusions: This meta-analysis indicates a strong association between schizophrenia and an elevated risk of developing diabetes, suggesting that schizophrenia may function as an independent risk factor for T2DM.

Introduction: Metabolic dysfunction-associated steatohepatitis (MASH) is increasingly becoming a prevalent cause of hepatocellular carcinoma (HCC). Our study examines the burden of MASH-related HCC globally, regionally, and nationally, along with associated risk factors from 1990 to 2019, considering variables such as age, sex, and socioeconomic status. Objective: We aimed to report the global, regional, and national burden of liver cancer due to MASH and its attributable risk factors between 1990 and 2019, by age, sex, and sociodemographic index (SDI). Methods: Utilizing the Global Burden of Disease 2019 project, we analyzed data on prevalence, mortality, and disability-adjusted life years (DALYs) for liver cancer attributable to MASH across 204 countries. We provided counts and rates per 100,000 population, including 95% uncertainty intervals. Results: In 2019, there were 46.8 thousand cases of MASH-related HCC, leading to 34.7 thousand deaths, and 795.8 thousand DALYs globally. While the prevalence increased by 19.8% since 1990, the death and DALY rates decreased by 5.3% and 15.1%, respectively. The highest prevalence was in High-income Asia Pacific, with the greatest increases observed in Australasia, Central Asia, and High-income North America. Southern Sub-Saharan Africa reported the highest death rate, while the lowest rates were in parts of Latin America, Central Sub-Saharan Africa, and Eastern Europe. DALY rates were the highest in Southern Sub-Saharan Africa and the lowest in Tropical Latin America. Discussion: The burden of MASH-related HCC is expected to rise slightly over the next decade. This disease, which is not associated with the SDI, remains a major public health problem. In addition, the escalating rates of obesity, demographic shifts, and an aging population could position MASH as a leading factor in liver cancer cases, surpassing viral hepatitis. It is imperative, therefore, that the forthcoming years see the implementation of strategic interventions aimed at the early detection and prevention of liver cancer associated with MASH.

Background: Risk scores facilitate the assessment of mortality risk in patients with community-acquired pneumonia (CAP). Despite their utilities, there is a scarcity of evidence comparing the various RS simultaneously. This study aims to evaluate and compare multiple risk scores reported in the literature for predicting 30-day mortality in adult patients with CAP. Methods: A retrospective cohort study on patients diagnosed with CAP was conducted across two hospitals in Colombia. The areas under receiver operating characteristic curves (ROC-curves) were calculated for the outcome of survival or death at 30 days using the scores obtained for each of the analyzed questionnaires. Results: A total of 7454 potentially eligible patients were included, with 4350 in the final analysis, of whom 15.2% (662/4350) died within 30 days. The average age was 65.4 years (SD: 21.31), and 59.5% (2563/4350) were male. Chronic kidney disease was 3.7% (9.2% vs. 5.5%; p < 0.001) (OR: 1.85) higher in subjects who died compared to those who survived. Among the patients who died, 33.2% (220/662) presented septic shock compared to 7.3% (271/3688) of the patients who survived (p < 0.001). The best performances at 30 days were shown by the following scores: PSI, SMART-COP and CURB 65 scores with the areas under ROC-curves of 0.83 (95% CI: 0.8–0.85), 0.75 (95% CI: 0.66–0.83), and 0.73 (95% CI: 0.71–0.76), respectively. The RS with the lowest performance was SIRS with the area under ROC-curve of 0.53 (95% CI: 0.51–0.56). Conclusion: The PSI, SMART-COP and CURB 65, demonstrated the best diagnostic performances for predicting 30-day mortality in patients diagnosed with CAP. The burden of comorbidities and complications associated with CAP was higher in patients who died. [ABSTRACT FROM AUTHOR]

Introduction: Drug therapy problems (DTPs) continuously occur in hospitalized patients. This study aims to emphasize the role of clinical pharmacists in evaluating the DTP's frequencies, causes, severity ratings, and contributing factors at a general surgery ward in Jordan. Methods: This prospective observational study was conducted at one of the major teaching and referral hospitals in Jordan. Data were collected through clinical pharmacist reviews of paper and electronic medical records as well as patient interviews. DTPs were identified using Cipolle's classification system and rated for severity on a scale of 10. Multiple linear regression was performed to identify factors contributing to DTPs. Drug classes primarily associated with DTPs were specified. Results: During enrollment, a total of 80 patients were recruited in this study. The mean age of the enrolled patients was 52.35 ± 14.82 years, and 49 (61.25%) of them were males. Within the study period, 192 DTPs were identified by clinical pharmacists in 87.5%of the total recruited patients. The mean number of DTPs per patient was 2.40 ± 1.83. The most common categories of DTPs were "needs additional therapy" 46 (23.96%), "unnecessary drug therapy" 45 (23.44%), and "dosage too low" 39 (20.31%). Of the total DTPs, 127 (66.15%) were rated as severe. Multiple linear regression revealed that patients' length of hospital stay and the number of current medications had a statistically significant effect on the number of DTPs identified during hospitalization. Endocrine and metabolic drugs 51 (26.56%) and cardiovascular drugs 36 (18.75%) were the most frequent classes of drugs contributing to DTPs. Conclusion: DTPs are common in the general surgery ward. Clinical pharmacists can provide medication reviews for surgical patients to identify DTPs and rate their severities. Detecting risk factors for DTPs and the most common drug classes associated with them can assist in decision-making relevant to reducing DTPs in the surgical ward. [ABSTRACT FROM AUTHOR]

Introduction. Incidence of early-onset colorectal cancer (EOCRC), defined as colorectal cancer (CRC) in individuals aged < 50 years, is rising worldwide. Despite the increasing international scientific production on EOCRC, research is limited in Colombia. The objective of this study was to characterize the clinical features of adults with EOCRC and late-onset CRC (LOCRC, CRC in individuals aged ≥ 50 years). Methods. An observational, retrospective, cross-sectional study was conducted with CRC patients ≥ 18 years old at one medical center in Medellín, Colombia. Clinical and pathological data were retrieved from the Institutional Cancer Registry. Two analysis groups were established: EOCRC and LOCRC. The Chi-Square test was applied to compare the variables of interest between both groups. Results. The sample included 1,202 patients, 53.5% were female (N=643) and the median age was 65 years (interquartile range: 55-73). EOCRC represented 15.9% (N=192). LOCRC tended to have more history of cardiometabolic diseases and smoking (p<0.001) than EOCRC. CRC family history was proportionally more frequent in EOCRC (7.3% vs 3.8%; p=0.028) than in LOCRC. Right-sided tumors were more common in LOCRC (30.4% vs 21.9%; p=0.041) and left-sided tumors in EOCRC (30.7% vs 23.2%; p=0.041). Only one patient had inflammatory bowel disease history. Conclusion. EOCRC is clinically distinct from LOCRC regarding pathological and toxicological history as well as tumor location. Our findings provide valuable insights for enhancing clinical decision-making, particularly in relation to age at onset in Colombian CRC patients. [ABSTRACT FROM AUTHOR]

To be convincing, an observational or nonrandomized study of causal effects must demonstrate that its conclusions cannot be readily explained by a small unmeasured bias in the way individuals were assigned to treatment or control. The Bahadur relative efficiency of a sensitivity analysis compares the performance of different test statistics or different research designs when sensitivity to unmeasured bias is appraised: better statistics and better designs exhibit insensitivity to larger biases. Bahadur efficiency is relevant here because, unlike Pitman efficiency, it can depict efficiency with an effect that is not trivially small: every trivially small treatment effect is sensitive to trivially small biases. The Bahadur efficiency of a sensitivity analysis has been used by various authors in the simple case of matched pairs, but the technical issues are more complex in the case of blocks larger than pairs, and they are developed here for the first time. Choosing a better test statistic for a block design, or choosing a better block size—larger than pairs—can result in enormous increases in the efficiency of a sensitivity analysis. An adaptive choice of test statistic can ensure the better Bahadur efficiency of two competing statistics. An R package weightedRank implements the methods, contains the example and reproduces its analysis. for this article are available online. [ABSTRACT FROM AUTHOR]

Introduction: The efficacy and safety of tildrakizumab for the treatment of plaque psoriasis were demonstrated by randomized clinical studies, but the reappraisal of prolonged experiences in the clinical practice helps to optimize the use of this biologic drug. The aim of this study was to evaluate the long-term efficacy of tildrakizumab in patients with moderate-to-severe psoriasis in the real world. Methods: This is a long-term retrospective observational study in a real-life setting. Overall, 136 adult patients with moderate-to-severe plaque psoriasis and treated with tildrakizumab were included. Results: One hundred percent reduction of Psoriasis Area Severity Index (PASI100) was reached by 21.7% of patients at 4 weeks of therapy and by 51.2% at week 16, and the proportion of patients with this improvement was between 66.9% and 64.5% from 36 weeks to 3 years. The mean PASI of the cohort progressively improved from 12.6 at baseline to 1.8 at week 36 and was stable at 1 year, 2 years and 3 years. We could not confirm a previous observation that patients naïve to biologic had a better response, but we observed that those with a short history of psoriasis had a higher probability of 90% PASI reduction (PASI90) or PASI 100 within 36 weeks, suggesting that early treatment could be useful. Conclusion: This long-term observation in the real life of patients with moderate-to-severe plaque psoriasis receiving tildrakizumab 100 mg showed that PASI100 can be obtained in a high proportion of patients by week 36 and be maintained for up to 3 years.

Background. The (embryonic lethal, abnormal vision, drosophila)-like protein 1 (ELAVL1) is a newly discovered protein associated with cerebral ischemic/reperfusion (I/R) injury. However, little is known of ELAVL1 in ischemic stroke patients. Objectives. To investigate the clinical significance of collateral circulation and serum ELAVL1 in patients with carotid atherosclerosis (CAS) and ischemic stroke. Materials and methods. The present prospective cohort investigation included 317 ischemic stroke patients and 300 CAS patients admitted between March 2020 and March 2022. Collateral circulation was measured using digital subtraction angiography (DSA) and graded using the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grading system. Enzyme-linked immunosorbent assays (ELISAs) were used to measure serum ELAVL1, C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). The serum levels of total cholesterol (TC), triglyceride (TG), high-density leptin cholesterol (HDL-C), and low-density leptin cholesterol (LDL-C) were also measured. Results. The serum levels of ELAVL1, CRP, IL-6, TNF-α, and LDL-C were all markedly higher, while HDL-C was significantly lower in ischemic stroke patients compared to the CAS patients. Serum ELAVL1 was markedly higher in ASITN/SIR grade 0-1 patients compared to grade 2-4 patients. Also, ELAVL1 correlated positively with serum CRP, IL-6, TNF-α, TC, and LDL-C, and negatively with HDL-C. Receiver operating characteristic (ROC) curves showed that ELAVL1 and collateral circulation have the potential to be used as biomarkers for the diagnosis of ischemic stroke. Meanwhile, CRP, IL-6, TNF-α, HDL-C, ASITN/SIR grading, and ELAVL1 were independent risk factors for ischemic stroke. Conclusions. We found that serum ELAVL1 was associated with clinical outcomes of ischemic stroke patients, while the combination of ELAVL1 and collateral circulation could be used as a potential biomarker for ischemic stroke diagnosis.

Objective: To evaluate age-specific multimorbidity patterns and morbidity burden on mortality and healthcare expenditure across age groups. Patients and Methods: Retrospective observational study between January 1, 2009 to December 31, 2017 using electronic health records in Hong Kong: Individuals were stratified by age (< 50, 50–64, 65–79, ≥ 80), and sub-classified by number of morbidities (0, 1, 2, 3, ≥ 4) out of 21 common chronic conditions. Clustering analyses were conducted to identify specific patterns of multimorbidity. Association between the number as well as combinations of morbidities and all-cause mortality and public expenditure was examined. Results: 4,562,832 individuals with a median follow-up of 7 years were included. Mental disorders were the top morbidities among young individuals, while cardiovascular diseases were prevalent in the elderly. An increased number of morbidities was associated with a greater relative risk for mortality and medical expenditure, and this relationship was stronger among younger patients. Compared to individuals in the same age group without morbidity, the hazard ratios (HR; 95% CI) of all-cause mortality in patients aged < 50 and ≥ 80 with two comorbidities 3.81 (3.60–4.03) and 1.38 (1.36–1.40), respectively, which increased to 14.22 (9.87–20.47) and 2.20 (2.13–2.26), respectively, as the number of morbidities increased to ≥ 4. The stroke-hypertension cluster was shown to be associated with the highest HR of mortality 2.48 (2.43–2.53) among all identified clusters arising from the clustering analysis. Conclusion: Given the stronger association between multimorbidity and all-cause mortality and greater opportunity costs in younger populations, prevention and management of early-onset multimorbidity are warranted.

Background: Research finds a lack of structure as well as varying and incomplete content in intrahospital handovers. This study aimed to improve intrahospital handovers by implementing structured ISBAR communication (identification, situation, background, assessment and recommendation). Methods: This quality improvement study was conducted observing 25 handovers given by nurses from the intensive care unit to nurses from general medical wards at baseline and after the implementation of the ISBAR communication tool. The 26-item ISBAR scoring tool was used to audit the handovers. In addition, the structure of the ISBAR communication and time spent on the handovers were observed. Results: There were no significant improvements from baseline to post-intervention regarding adherence to the ISBAR communication scoring tool. The structure of the handovers improved from baseline to post-intervention (p = 0.047). The time spent on handovers declined from baseline to post-intervention, although not significantly. Conclusions: The items in the ISBAR communication scoring tool can act as a guide for details that need to be reported during intrahospital handovers to strengthen patient safety. Future research calls for studies measuring satisfaction among nurses regarding using different handover tools and studies using multifaceted training interventions. [ABSTRACT FROM AUTHOR]

Background: Lateral and medial elbow tendinopathies are common soft tissue disorders affecting 1–3% of the general population, causing significant pain and functional impairment in the elbow and upper limb. While often associated with overuse and repetitive strain, their exact etiology, including potential associations with prior injuries in adjacent joints, remains unclear. This preliminary study aims to explore the distribution of lateral and medial elbow tendinopathies and investigate the occurrence of previous lesions in adjacent joints among diagnosed individuals, providing foundational insights for future research. Methods: A multicenter cross-sectional observational study was conducted involving 90 subjects diagnosed with lateral and/or medial elbow tendinopathy. The data collection occurred during the initial consultations, including demographic information, clinical assessments, and history of prior injuries in adjacent joints. Results: Among the sample, 44.4% reported prior injuries to adjacent joints in the affected upper limb, with 45.6% of these injuries identified as musculotendinous in nature. The analysis also showed that the type of elbow tendinopathy was significantly associated with sex (p = 0.01) and occupational origin (p = 0.022). Conclusions: While a notable percentage of the subjects reported prior musculoskeletal injuries in the same limb, the study's geographic limitations and reliance on self-reported data introduce potential recall bias. These preliminary findings suggest a possible relationship between prior adjacent joint injuries and elbow tendinopathy. Further research with larger sample sizes and more rigorous study design is needed to confirm these observations and explore the underlying mechanisms. [ABSTRACT FROM AUTHOR]

Abstract Background Frailty often requires intensive care, and the admission outcomes of frail patients are often poor. However, owing to the lack of reliable diagnostic indicators, quickly identifying frailty is challenging. The present study aimed to explore the associations of the platelet/high-density lipoprotein cholesterol ratio (PHR; a novel inflammatory indicator) with frailty and all-cause mortality. Methods The present study analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018. Frailty was assessed on the basis of the 49-item Frailty Index. The associations of the PHR with frailty and long-term survival prognosis were explored through weighted logistic regression, weighted restricted cubic spline (RCS), and weighted Cox regression, with adjustments for demographic factors, lifestyle, blood lipids, medication history, and complications. In addition, subgroup and interaction analyses were conducted. Finally, several sensitivity analyses were performed. Results A total of 15,615 adult participants were included, with 7,928 women (53.63%) and an average age of 60.76 years. After fully adjusting for confounding variables, the prevalence of frailty in the highest PHR quartile group of was significantly greater than that in the lowest quartile group (OR: 1.23, 95% CI: 1.04–1.47; P = 0.02). The RCS showed that the inflection point was 166.7. Before and after the inflection point, the PHR was negatively associated (OR: 0.88, 95% CI: 0.80–0.97, P = 0.01) and positively associated (OR: 1.10, 95% CI: 1.02–1.19, P = 0.01) with frailty, respectively. Subgroup analysis suggested that the association between PHR and frailty was stronger in women than in men. A total of 5,544 frail participants were included in the survival analysis. The RCS revealed that the PHR was associated with the all-cause mortality risk of frail participants in a U-shaped manner, with an inflection point of 240.4. Before and after the inflection point, the PHR decreased (HR: 0.89, 95% CI: 0.81–0.97, P = 0.01) and the all-cause mortality risk increased (HR: 1.08, 95% CI: 1.02–1.14, P = 0.01), respectively. Conclusion The present study suggests that there is a J-shaped association between PHR and frailty in the adult population of the United States and that the association between the PHR and frailty is stronger in women. In addition, the PHR has a U-shaped relationship with the all-cause mortality risk of frail patients.

Abstract Background Malnutrition is a complication of chronic kidney disease (CKD). Whether malnutrition, assessed via the geriatric nutritional risk index (GNRI), is associated with the incidence and risk of CKD in older individuals remains unclear. Methods Data from the National Health and Nutrition Examination Survey and the UK Biobank database were used. Older participants over 60 years old with available data for GNRI assessment and CKD diagnosis were enrolled. Logistic regression models and Cox regression models were used to assess associations between the geriatric nutritional risk index and the risk of and mortality associated with CKD. Results This study enrolled 13,162 participants from the NHANES and 66,326 participants from the UK Biobank. We identified 6,135 and 16,662 CKD patients in the NHANES and UK Biobank, respectively, with the majority being male (74% in the NHANES and 52% in the UK Biobank). The average age of CKD patients was 72.3 (SD 7.2) years in the NHANES and 64.9 (SD 2.9) years in the UK Biobank. The median follow-up times of older CKD patients were 81 months and 162 months in the NHANES and UK Biobank, respectively. According to the cross-sectional analysis, individuals with a lower GNRI had an increased likelihood of having CKD, with odds ratios of 1.38 (95% CI: 1.05–1.80, P = 0.020) in the NHANES and 2.35 (95% CI: 1.89–2.92, P

Objective: To determine the efficacy and safety of the Yinmei Kuijie decoction combined with 5-aminosalicylic acid (5-ASA) in treating mildly to moderately active ulcerative colitis (UC) under real-world conditions. Methods: This multicenter, prospective, non-randomized, observational study will be conducted in real-world settings. A total of 204 eligible patients will be consecutively enrolled in the study. Patients in the combination treatment group will receive Yinmei Kuijie decoction in combination with 5-ASA, whereas those in the control group will be treated with 5-ASA alone. The primary endpoint will be a clinical response at week 12, defined as a ≥3 point and ≥30% reduction from baseline in the Mayo total score with ≥1 reduction in rectal bleeding or rectal bleeding score = 0 or 1. Secondary efficacy endpoints at week 12 will include health-related quality of life, mucosal healing, and inflammation indicators. Conclusion: The results of this study may provide evidence of the efficacy and safety of Yinmei Kuijie decoction combined with 5-ASA in treating patients with mildly to moderately active UC under real-world principles. The results will provide a basis for further confirmatory studies on the efficacy of Yinmei Kuijie decoction.

Abstract Background The Netherlands is one of few countries worldwide which has used the bivalent HPV vaccine for girls-only for over a decade. This allows assessment of vaccine effectiveness (VE) against female genital HPV DNA-positivity of this vaccine in an observational post-licencing real-world setting. Additionally, it is unclear whether catch-up vaccination campaigns result in similar VE as routine vaccination. Therefore, type-specific and grouped VE were assessed and compared for women who had been eligible for catch-up vaccination at 13–16 years with those who had been eligible for routine vaccination at 12 years. Methods PASSYON is a Dutch biennial repeated cross-sectional (2011–2021) study among sexual health clinic clients aged 16–24 years old. Women provided self-collected vaginal samples, questionnaires on demographics and sexual behaviour were administered, and women self-reported HPV vaccination status. Samples were analysed using a PCR-based assay (SPF10-LiPA25). Type-specific and grouped VE estimates, adjusted with propensity score stratification, were assessed against genital positivity for 14 HPV types. VE for targeted and non-targeted genotypes were compared between women who had been eligible for the catch-up and those who had been eligible for routine vaccination. Results The study included 4488 female participants who had been eligible for HPV vaccination and provided genital swabs (1561 eligible for catch-up, 2927 for routine vaccination). Very high VE against genital HPV-16 and HPV-18 was observed (resp. 93.5% and 89.5%) and significant cross-protection against six other genotypes (HPV-31/33/35/45/52/58), varying from 18.0% (HPV-52) to 79.6% (HPV-45). VE estimates were comparable between women who had been eligible for the catch-up campaign and those eligible for routine vaccination: VE HPV-16/HPV-18: 92.2% (95%CI: 87.9–94.9) vs. 91.8% (95%CI: 86.0–95.2). Conclusions In real-world settings, the VE of bivalent vaccine is high against targeted genotypes, with cross-protection against 6 other genotypes. Catch-up campaigns up to age 16 years can be as effective as routine vaccination at age 12, although it is recommendable to provide HPV vaccination at an age at which most are likely not sexually active yet. This may inform countries considering catch-up campaigns when introducing or extending the use of HPV vaccination within their national immunisation programmes.

Background: Given the various issues that Polycystic ovary syndrome (PCOS) can cause in women and the need to address its consequences and provide solutions to improve the course of the disease and alleviate its symptoms, the present study aimed to investigate the association between body image and eating disorders, anxiety, and depression in individuals with PCOS.Methods: This observational study was conducted on 150 girls with PCOS in Hamadan, Iran in 2023. Convenience sampling method was used to select unmarried girls of reproductive age with PCOS. The participants were asked to complete certain questionnaires, including demographic questionnaires, the eating disorders examination questionnaire (EDE-QS), the hospital anxiety and depression scale (HADS), and the body shape questionnaire (BSQ). The collected data were analyzed using Stata-13 software, with a significance level of P

Abstract Background While traditional medicine (TM) is employed by a significant portion of the global population for managing health issues, clinical guidelines and state recommendations often overlook this practice. The aim of this study was to describe the frequency of use of TM to control 3 metabolic risk factors (MRF): hypertension, hypercholesterolemia, and hyperglycaemia; and the sociodemographic, economic, and clinical characteristics associated with the use of TM. Methods Cross-sectional descriptive study that analyses data obtained from a representative population survey in 2 health districts, one urban in the south of Quito and another in a forested rural area with diverse ethnic groups in Esmeraldas, Ecuador. We include 602 individuals with at least one MRF. We calculated the proportion of people reporting the regular use of TM (herbal or traditional remedy) to control their MRF and we assessed potential associations with sociodemographic, economic, and clinical characteristics with a multivariable logistic regression model. Results In two very different sociocultural contexts in Ecuador we found that use of TM to control MRF was frequent (39.4% in Esmeraldas, 31.1% in Quito), frequently in combination with CM. There is a notable percentage of people, 33.9% in Esmeraldas and 39.0% in Quito, who did not take any treatment for their MRF, and the remainder used CM alone. In both settings, an individual’s education lever was significantly associated with TM use. Whereas in Quito individuals with higher education more frequently treated their MRF with TM (aOR 2.04, 95% CI 1.03–3.90), in the rural, hard-to-reach context of Esmeraldas, it was more frequent among people with no formal schooling (aOR: 3.76; 95%CI 1.59–8.88), as well as those of younger age (aOR by year: 0.97; 95% CI 0.95–0.99) and afro ethnicity (aOR: 2.13; 95%CI 1.02–4.45). Conclusion Traditional medicine is used by a significant proportion of the population in Ecuador, highlighting the need for a more accessible and intercultural healthcare approach. The health system should ensure access to the necessary information and resources for the management of their metabolic risk factors.

Abstract Background Adverse pregnancy outcomes have reached epidemic proportions in recent years with serious health ramifications, especially for diverse cancers risk. Therefore, we carried out an umbrella review to systematically evaluate the validity and strength of the data and the extent of potential biases of the established association between adverse pregnancy outcomes and cancers risk in both mother and offspring. Methods PubMed, Embase, and Web of Science databases were searched from inception until 18 January 2024. Meta-analyses of observational studies investigating the relationship between adverse pregnancy outcomes and multiple cancers risk in both mother and offspring were included. Evidence certainty was assessed using Grading of Recommendations, Assessment, Development, and Evaluation. The protocol for this umbrella review was prospectively registered in PROSPERO (CRD42023470544). Results The search identified 129 meta-analyses of observational studies and 42 types of cancer. Moderate certainty of evidence, exhibiting statistical significance, has been observed linking per kilogram increase in birth weight to a heightened risk of breast cancer (OR = 1.07, 95% CI = 1.02–1.12), prostate cancer (OR = 1.02, 95% CI = 1.00–1.05), leukemia (OR = 1.18, 95% CI = 1.13–1.23), and acute lymphoblastic leukemia in offspring (OR = 1.18, 95% CI = 1.12–1.23); rubella infection during pregnancy to an increased risk of leukemia in offspring (OR = 2.79, 95% CI = 1.16–6.71); and a linear dose–response association between an increase in the proportion of optimal birth weight and an elevated risk of acute lymphoblastic leukemia in offspring (OR = 1.16, 95% CI = 1.09–1.24), respectively. Conclusions Although some adverse pregnancy outcomes have clinically promising associations with risk of several cancers in both mother and offspring, it is essential to conduct additional research to solidify the evidence, evaluate causality, and ascertain clinical utility.

Abstract Background The procedures used to assess the methodological quality and risk of bias (RoB) of systematic reviews of observational dental studies have not been investigated. The purpose of this research was to examine the way that authors of systematic reviews of epidemiological observational studies published in dentistry conducted the methodological assessment of those primary studies. In the present article, we aimed to assess the characteristics and the level of reporting of tools used to assess the methodologies of these reviews. Methods We searched Scopus and the Web of Science from their inceptions to June 2023 for systematic reviews with meta-analyses of observational studies published in dentistry. Document selection and data extraction were performed in duplicate and independently by two authors. In a random sample of 10% of the systematic reviews, there was an agreement of more than 80% between the reviewers; data selection and extraction were conducted in the remaining 90% of the sample by one author. Data on the article and systematic review characteristics were extracted and recorded for descriptive reporting. Results The search in the two databases resulted in the inclusion of 3,214 potential documents. After the elimination of duplicates and the application of the eligibility criteria, a total of 399 systematic reviews were identified and included. A total of 368 systematic reviews reported a methodological tool, of which 102 used the Newcastle–Ottawa scale. Additionally, 76 systematic reviews stated the use of a modified methodological tool. Information about the approach of assessing the methodological quality or RoB of primary studies but reporting no tool or tool name occurred in 25 reviews. Conclusions The majority of authors of systematic reviews of epidemiological observational studies published in dentistry reported the tools used to assess the methodological quality or RoB of the included primary studies. Modifying existing tools to meet the individual characteristics of various studies should be considered.

Abstract Background Abnormal lipid metabolism is linked to intervertebral disc degeneration (IVDD), sciatica, and low back pain (LBP), but it remains unclear whether targeted interventions can prevent these issues. This study investigated the causal effects of lipid-lowering drug use on IVDD, sciatica, and LBP development. Methods Single-nucleotide polymorphisms (SNPs) linked to total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-C), and non-high-density-lipoprotein cholesterol (non-HDL-C) were obtained from the Global Lipids Genetics Consortium’s genome-wide association study (GWAS). Genes near HMGCR, PCSK9, and NPC1L1 were selected to represent therapeutic inhibition targets. Using Mendelian randomization (MR) focusing on these drug targets, we identified causal effects of PCSK9, HMGCR, and NPC1L1 on the risk of developing IVDD, sciatica, and LBP, with coronary heart disease risk serving as a positive control. Using summary data from Mendelian randomization (SMR) analysis, we evaluated potential therapeutic targets for IVDD, sciatica, and LBP through protein quantitative trait loci (pQTL). The genetic associations with IVDD, sciatica, LBP, and coronary heart disease were derived from FinnGen (discovery) and UK Biobank (replication). Additionally, a cross-sectional observational study was performed using data from the National Health and Nutrition Examination Survey (NHANES) to further investigate the connection between LBP and statin use, with a sample size of 4343 participants. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated to assess the outcomes. Results The NHANES-based cross-sectional study indicated that non-statin use was associated with an increased risk of developing LBP (OR = 1.29, 95% CI [1.04, 1.59], P = 0.019). Moreover, Inverse-variance weighting (IVW) analysis revealed that NPC1L1-mediated reductions in TC, LDL-C, and non-HDL-C concentrations were associated with a decreased risk of developing IVDD (P = 9.956E-03; P = 3.516E-02; P = 1.253E-04). Similarly, PCSK9-mediated reductions in LDL-C and TC concentrations were linked to a lower risk of developing sciatica (P = 3.825E-02; P = 2.709E-02). Sensitivity analysis confirmed the stability and reliability of the MR results. MST1 (macrophage stimulating 1) levels was inversely associated with IVDD, sciatica, and LBP risks. Conclusion The results of cross-sectional study suggested that non-use of statins was positively correlated with LBP. The results of Mendelian randomization study suggest that NPC1L1 could lower the risk of developing IVDD by reducing TC, LDL-C, and non-HDL-C levels. Additionally, PCSK9 may reduce the risk of developing sciatica by lowering LDL-C and TC levels. In contrast, HMGCR appears to have no significant effect on IVDD, sciatica, or LBP development. Nonetheless, further research is needed to verify these preliminary results. MST1 warrants further exploration as a potential therapeutic target. It is necessary to do further research to validate these findings.

Purpose We investigated injury rates over the previous 12 months, associated factors, and injury characteristics in a cohort of recreational functional fitness training participants. Methods A cross-sectional study was conducted with a convenience sample of 304 participants (175 females and 129 males; mean age: 32.6 ± 7.2 years; mean training experience: 27.6 ± 21.4 months) from three CrossFit™ affiliated gyms in Brazil. Data were collected via face-to-face interviews, using a questionnaire that focused on functional fitness-related injuries in the previous year and included data on participant demographics and training regimens. Results Out of all the participants, 82 (27.0%) experienced a functional fitness-related injury with an incidence rate of 1.22 injuries/1000 hours of participation. The practice of other sports activities and dissatisfaction with joint mobility of the shoulders increased the odds of being injured in the multivariate logistic regression. The shoulder was the most affected body part (26.6%). A gradual injury mechanism was the most commonly reported (36.2%), and joint sprain (18.1%), cartilage injury (11.7%), and tendinopathy (10.6%) were the most common pathology types. Concerning symptom severity, in most cases, participants referred to the injury as severe (36.2%), with a sporting time loss greater than 28 days (50%). Conclusions Injury prevalence over the last 12 months was 27.0% (82/304), with an incidence of 1.22 injuries/1000 hours. The practice of other sports activities and dissatisfaction with joint mobility of the shoulders increased the odds of injury. Most injuries occurred in the shoulder, with a gradual injury mechanism, and participants classified symptoms as severe, leading to significant sporting time loss.

Abstract Background Safety remains a significant concern for biologic drugs, and studies are needed to ensure a comparable safety profile for biosimilars and their legacy treatments. Using Canadian administrative health data from 2015–2019, we compared the incidence of serious infection between biosimilars and bio-originators initiators for etanercept and infliximab, two of the most commonly used biologics during this time. Methods We performed a retrospective cohort study using pan-Canadian data (except Quebec) from the National Prescription Drug Utilization Information System linked to hospitalization data. We studied new users of infliximab or etanercept (January/2015-December/2019) and compared incidence rates of serious infection, defined as those which required hospitalization, by using Cox regression models adjusted by biological sex, age at treatment initiation, prior corticosteroid or biologic, province, and calendar year. Results We studied 6,583 etanercept users (mean age 62) and 7,202 infliximab users (mean age 45). Hospitalization with infections occurred in 7% of infliximab and 2% of etanercept users. Comparing the risk of infection between biosimilar to bio-originator, the adjusted hazard ratio (95% confidence interval) was 1.33 (0.77, 2.30) for etanercept and 0.93 (0.72, 1.18) for infliximab. Conclusions Our study found no clear difference between etanercept and infliximab biosimilars and their bio-originators for infection incidence, suggesting a similar safety profile.

This study aims to emphasize the role of clinical pharmacists in evaluating the DTP’s frequencies, causes, severity ratings, and contributing factors at a general surgery ward in Jordan.Methods: This prospective observational study was conducted at one of the major teaching and referral hospitals in Jordan. Data were collected through clinical pharmacist reviews of paper and electronic medical records as well as patient interviews. DTPs were identified using Cipolle’s classification system and rated for severity on a scale of 10. Multiple linear regression was performed to identify factors contributing to DTPs. Drug classes primarily associated with DTPs were specified.Results: During enrollment, a total of 80 patients were recruited in this study. The mean age of the enrolled patients was 52.35 ± 14.82 years, and 49 (61.25%) of them were males. Within the study period, 192 DTPs were identified by clinical pharmacists in 87.5%of the total recruited patients. The mean number of DTPs per patient was 2.40 ± 1.83. The most common categories of DTPs were “needs additional therapy” 46 (23.96%), “unnecessary drug therapy” 45 (23.44%), and “dosage too low” 39 (20.31%). Of the total DTPs, 127 (66.15%) were rated as severe. Multiple linear regression revealed that patients’ length of hospital stay and the number of current medications had a statistically significant effect on the number of DTPs identified during hospitalization. Endocrine and metabolic drugs 51 (26.56%) and cardiovascular drugs 36 (18.75%) were the most frequent classes of drugs contributing to DTPs.Conclusion: DTPs are common in the general surgery ward. Clinical pharmacists can provide medication reviews for surgical patients to identify DTPs and rate their severities. Detecting risk factors for DTPs and the most common drug classes associated with them can assist in decision-making relevant to reducing DTPs in the surgical ward.Keywords: drug therapy problems, clinical pharmacist, surgery ward, observational study

Abstract Background Risk scores facilitate the assessment of mortality risk in patients with community-acquired pneumonia (CAP). Despite their utilities, there is a scarcity of evidence comparing the various RS simultaneously. This study aims to evaluate and compare multiple risk scores reported in the literature for predicting 30-day mortality in adult patients with CAP. Methods A retrospective cohort study on patients diagnosed with CAP was conducted across two hospitals in Colombia. The areas under receiver operating characteristic curves (ROC-curves) were calculated for the outcome of survival or death at 30 days using the scores obtained for each of the analyzed questionnaires. Results A total of 7454 potentially eligible patients were included, with 4350 in the final analysis, of whom 15.2% (662/4350) died within 30 days. The average age was 65.4 years (SD: 21.31), and 59.5% (2563/4350) were male. Chronic kidney disease was 3.7% (9.2% vs. 5.5%; p

Physical inactivity poses a significant public health challenge. Numerous studies have argued that urban parks can promote physical activity (PA). However, evidence of physical activity observed over long periods of time in parks is still very lacking. Our serial cross-sectional study within urban parks in Shanghai investigated seasonal and daily variations in PA. Employing a geographically and temporally weighted regression (GTWR) model, we established spatiotemporal relationships between urban park characteristics and PA levels. We found that (1) Highest PA levels occur in winter, while the lowest levels are observed in summer, with a V-shaped daily pattern. (2) Robust and significant associations between specific park characteristics and PA levels, while other characteristics exhibited varying associations in different temporal and spatial contexts. These insights offer valuable guidance for urban planners and park designers aiming to create more active and sustainable urban environments.

Interactions among intestinal bacteria and the immune system contribute to the maintenance of a functional intestinal barrier in healthy individuals, and possibly to systemic immune activity. We hypothesized that intestinal bacteria would be associated with systemic biomarkers of innate and adaptive immune responses in healthy adults. 79 immune function markers were subjected to factor analysis resulting in 17 Immune Factors (IFs), each composed of 2-10 immune variables. Bacterial taxa from stool samples were identified at the family and genus levels by 16S rRNA amplicon sequence analysis and their read counts and relative abundances were utilized in a multiple linear regression model to identify microbial taxa associated with the IFs. A total of 10 significant associations were identified between bacterial taxa and IFs. The family Rikenellaceae showed a positive association with innate IF5 (including 5 chemokines, 2 cytokines, 2 adhesion molecules, and the macrophage metabolite neopterin) and a negative association with adaptive IF4 (including T-cells with activation marker HLA-DR). Additionally, Pseudomonadaceae and its genus Pseudomonas showed a negative relationship with innate IF5, and adaptive IF13 (including T-cell cytokines IL-10, IL-17, and IFN-γ) was negatively associated with Butyrivibrio and positively associated with Slackia. These associations suggest ongoing interactions between gut bacteria and the systemic immune system in healthy adults. The association of these taxa with the IFs may result from specific microbial-immune system interactions that play a role in maintenance of a healthy barrier integrity in our cohort of healthy adults. IMPORTANCE Chronic inflammation may develop over time in healthy adults as a result of a variety of factors, such as poor diet directly affecting the composition of the intestinal microbiome, or by causing obesity, which may also affect the intestinal microbiome. These effects may trigger the activation of an immune response that could eventually lead to an inflammation-related disease, such as colon cancer. Before disease develops it may be possible to identify subclinical inflammation or immune activation attributable to specific intestinal bacteria normally found in the gut that could result in future adverse health impacts. In the present study, we examined a group of healthy men and women across a wide age range with and without obesity to determine which bacteria were associated with particular types of immune activation to identify potential preclinical markers of inflammatory disease risk. Several associations were found that may help develop dietary interventions to lower disease risk.

Multiple sclerosis (MS) is an autoimmune-inflammatory and neurodegenerative disease of the central nervous system. The article analyses the ability of cladribine, which due to its selective lymphotoxic effect on activated cells and central effect on immunomodulation in brain tissue underwent successful clinical trials in 2010, when it was (temporarily) approved in Russia.Objective: to analyse the effect of cladribine tablets in daily practice on the course of MS over 3–4 year observational period after immune reconstitution therapy (IRT) in several neurological clinics from different regions of Russia.Material and methods. We collected data on 235 patients from 12 neurological clinics and regional MS centres who were followed for an average of 3.4 years after starting cladribine treatment.Results. An independent analysis of cases in which cladribine tablets were prescribed showed that the reason for prescribing cladribine was highly active MS (HARS) in 159 (67.7%) patients, rapidly progressive MS (RPMS) in 20 (8.5%), active relapsing-remitting MS – in 50 (21.3%) and secondary progressive MS with exacerbations – in 6 (2.5%). Only 12 (5.1%) of these patients had not previously received disease-modifying therapies (DMTs), i.e. in these cases the drug was the first DMT prescribed. Among patients who had received a second-line DMTs before switching to cladribine, 22 had previously received natalizumab, 5 had received ocrelizumab and only 1 had received fingolimod. Remaining patients (n=195) were switched from first-line DMTs. In all cases, a decrease in the frequency of exacerbations was observed during and after completion of the IRT course. Exacerbations between the first and second course of cladribine were observed in 36 patients (15.3% of all treated patients), including in almost half of the cases those who were switched from natalizumab (17 exacerbations or 47.2% of all exacerbations, that developed between the first and second course of therapy) and in three cases – from ocrelizumab (8.3 % of exacerbations that developed between the first and second course of therapy, or 60 % of all those switched from ocrelizumab to cladribine). After completion of full cladribine treatment during the four-year observation period, exacerbations occurred in 14 patients (6% of all patients included in the analysis), six of which occurred after switching from natalizumab.Conclusion. The results are generally consistent with the results of recently published meta-analyses and reviews, but the high likelihood of exacerbations in patients switched from second-line therapies such as natalizumab and ocrelizumab is noteworthy. Both drugs are prescribed for aggressive types of MS with exacerbations (highly active and rapidly progressive) who had a high frequency of exacerbations and an increase in Expanded Disability Status Scale (EDSS) scores prior to being prescribed these drugs. The switch from natalizumab is usually due to an increased risk of developing progressive multifocal encephalopathy with a high titre of antibodies against the JC-virus and the duration of natal izumab use of more than 2 years. It is likely that the resumption of MS activity after discontinuation of natalizumab is quite pronounced, and replacement with treatment with cladribine in tablet form is not able to completely prevent this. In this respect, such a switch does not appear to be optimal, in contrast to cases where first-line drugs are switched to cladribine.

Abstract Introduction The efficacy and safety of tildrakizumab for the treatment of plaque psoriasis were demonstrated by randomized clinical studies, but the reappraisal of prolonged experiences in the clinical practice helps to optimize the use of this biologic drug. The aim of this study was to evaluate the long-term efficacy of tildrakizumab in patients with moderate-to-severe psoriasis in the real world. Methods This is a long-term retrospective observational study in a real-life setting. Overall, 136 adult patients with moderate-to-severe plaque psoriasis and treated with tildrakizumab were included. Results One hundred percent reduction of Psoriasis Area Severity Index (PASI100) was reached by 21.7% of patients at 4 weeks of therapy and by 51.2% at week 16, and the proportion of patients with this improvement was between 66.9% and 64.5% from 36 weeks to 3 years. The mean PASI of the cohort progressively improved from 12.6 at baseline to 1.8 at week 36 and was stable at 1 year, 2 years and 3 years. We could not confirm a previous observation that patients naïve to biologic had a better response, but we observed that those with a short history of psoriasis had a higher probability of 90% PASI reduction (PASI90) or PASI 100 within 36 weeks, suggesting that early treatment could be useful. Conclusion This long-term observation in the real life of patients with moderate-to-severe plaque psoriasis receiving tildrakizumab 100 mg showed that PASI100 can be obtained in a high proportion of patients by week 36 and be maintained for up to 3 years.

Abstract Background Exercise Referral Schemes (ERSs) have been implemented across Western nations to stimulate an increase in adult physical activity but evidence of their effectiveness and cost-effectiveness is equivocal. Poor ERS uptake and adherence can have a negative impact on effectiveness and cost-effectiveness and, if patterned by socio-demographic factors, can also introduce or widen health inequalities. Different modes of ERS delivery have the potential to reduce costs and enhance uptake and adherence. The primary aim of this study was to examine the effect of different programmes of ERS delivery on scheme uptake and adherence. Secondary aims were to examine the effect of socio-demographic factors on scheme uptake and adherence, and the impact of delivery mode on the expected resource and corresponding costs of delivering core parts of the programme. Methods This was an observational cohort study with cost analysis. Routine monitoring data covering a three-year period (2019–2021) from one large UK ERS (number of patients = 28,917) were analysed. During this period three different programmes of delivery were operated in succession: standard (all sessions delivered face-to-face at a designated physical location), hybrid (sessions initially delivered face-to-face and then switched to remote delivery in response to the Covid-19 pandemic), and modified (sessions delivered face-to-face, remotely, or a combination of the two, as determined on a case-by-case basis according to Covid-19 risk and personal preferences). Multi-level binary logistic and linear regression were performed to examine the effect of programme of delivery and socio-demographic characteristics on uptake and adherence. Cost data were sourced from regional-level coordinators and through NERS audits supplied by national-level NERS managers and summarised using descriptive statistics. Results There was no effect of programme of delivery on scheme uptake. In comparison to those on the standard programme (who attended a mean of 23.1 exercise sessions) those on the modified programme had higher adherence (mean attendance of 25.7 sessions) while those on the hybrid programme had lower adherence (mean attendance of 19.4 sessions). Being older, or coming from an area of lower deprivation, increased the likelihood of uptake and adherence. Being female increased the chance of uptake but was associated with lower adherence. Patients referred to the programme from secondary care were more likely to take up the programme than those referred from primary care for prevention purposes, however their attendance at exercise sessions was lower. The estimated cost per person for face-to-face delivery of a typical 16-week cycle of the scheme was £65.42. The same cycle of the scheme delivered virtually (outside of a pandemic context) was estimated to cost £201.71 per person. Conclusions This study contributes new evidence concerning the effect of programme of delivery on ERS uptake and adherence and strengthens existing evidence concerning the effect of socio-economic factors. The findings direct the attention of ERS providers towards specific patient sub-groups who, if inequalities are to be addressed, require additional intervention to support uptake and adherence. At a time when providers may be considering alternative programmes of delivery, these findings challenge expectations that implementing virtual delivery will necessarily lead to cost savings.

Abstract Background Obesity has been linked to arterial stiffness, while no consensus was reached on the association. We aimed to clarify the association of general and central obesity with arterial stiffness by combining observational studies and Mendelian randomization (MR) study. Methods Two cross-sectional studies were performed in UK Biobank and Fuqing Cohort, respectively. Two-sample MR study was conducted using summary data of GWASs from GIANT consortium and UK Biobank. General obesity and central obesity were measured using body mass index (BMI) and waist circumference (WC), respectively. Arterial stiffness was measured by arterial stiffness index (ASI) in UK Biobank or branchial-ankle pulse wave velocity (baPWV) in Fuqing Cohort. Results Two observational studies found a consistent positive association of BMI and WC with arterial stiffness when adjusting for age, sex, education, smoking, alcohol drinking, physical activity, and LDL cholesterol. However, when additionally adjusting for metabolic traits (i.e., systolic blood pressure, diastolic blood pressure, blood glucose, triglycerides, high-density lipoprotein cholesterol, and WC or BMI), the association with BMI changed to be inverse. As compared to the lowest quintile group, the adjusted ORs across groups of second to fifth quintile were 0.93, 0.90, 0.83, and 0.72 in UK Biobank and 0.88, 0.65, 0.63, and 0.50 in Fuqing Cohort. In contrast, the positive relationship with WC remained stable with the adjusted ORs of 1.23, 1.46, 1.60, and 1.56 in UK Biobank and 1.35, 1.44, 1.77, and 1.64 in Fuqing Cohort. MR analyses provided supportive evidence of the negative association with BMI (OR = 0.97, 95%CI = 0.94–1.00) and the positive association with WC (OR = 1.14, 95%CI = 1.08–1.20). Conclusions Observational and genetic analyses provide concordant results that central obesity is independently related to arterial stiffness, while the role of general obesity depends on metabolic status.

Frailty was diagnosed using the Fried Frailty Phenotype (FP), while the Charlson Comorbidities Index (CCI) assessed the presence of chronic conditions. Data analysis was performed using SPSS 22.0. Binary logistic regression analysis was conducted with frailty as the dependent variable to identify risk factors. Patients were followed for one year to monitor readmission rates and all-cause mortality.Results: Multivariate logistic regression identified CCI grade (P=0.030), gender (OR=21.618, 95% CI: 4.062– 115.061, P < 0.001), age (OR=1.147, 95% CI: 1.086– 1.211, P < 0.001), bedridden state (OR=11.620, 95% CI: 3.282– 41.140, P < 0.001), arrhythmia (OR=14.414, 95% CI: 4.558– 45.585, P < 0.001), heart failure (OR=5.439, 95% CI: 1.029– 28.740, P < 0.05), along with several biochemical markers, as independent predictors of frailty. A predictive model was developed, demonstrating a robust discriminative ability with an area under the receiver operating characteristic curve (AUC) of 0.915. Statistically significant differences in readmission rates and all-cause mortality were observed among the frail, pre-frail, and non-frail groups (P< 0.001), with the frail group exhibiting the highest incidence of these adverse outcomes. Notably, frailty emerged as a significant predictor of readmission (P< 0.05) but not of all-cause mortality in this cohort.Conclusion: This study establishes a robust frailty prediction model for elderly hypertensive patients, highlighting the influence of CCI grade, gender, age, and other clinical and biochemical factors on frailty. The model offers a valuable tool for healthcare providers to identify at-risk elderly individuals, facilitating targeted intervention strategies for cardiovascular disease management.Keywords: frailty, hypertension, older people, observational study, prediction model

Abstract Background In northern rural Sweden, telemedicine is used to improve access to healthcare and to provide patient-centered care. In emergency care during on-call hours, video-conference systems are used to connect the physicians to the rest of the team – creating ‘distributed teams’. Patient participation is a core competency for healthcare professionals. Knowledge about how distributed teamwork affects patient participation is missing. The aim was to investigate if and how teamwork affecting patient participation, as well as clinicians’ perceptions regarding shared decision-making differ between co-located and distributed emergency teams. Methods In an observational study with a randomized cross-over design, healthcare professionals (n = 51) participated in authentic teams (n = 17) in two scripted simulated emergency scenarios with a standardized patient: one as a co-located team and the other as a distributed team. Team performances were filmed and observed by independent raters using the PIC-ET tool to rate patient participation behavior. The participants individually filled out the Dyadic OPTION questionnaire after the respective scenarios to measure perceptions of shared decision-making. Scores in both instruments were translated to percentage of a maximum score. The observational data between the two settings were compared using linear mixed-effects regression models and the self-reported questionnaire data were compared using one-way ANOVA. Neither the participants nor the observers were blinded to the allocations. Results A significant difference in observer rated overall patient participation behavior was found, mean 51.1 (± 11.5) % for the co-located teams vs 44.7 (± 8.6) % for the distributed teams (p = 0.02). In the PIC-ET tool category ‘Sharing power’, the scores decreased from 14.4 (± 12.4) % in the co-located teams to 2 (± 4.4) % in the distributed teams (p = 0.001). Co-located teams scored in mean 60.5% (± 14.4) when self-assessing shared decision-making, vs 55.8% (± 15.1) in the distributed teams (p = 0.03). Conclusions Team behavior enabling patient participation was found decreased in distributed teams, especially regarding sharing power with the patient. This finding was also mirrored in the self-assessments of the healthcare professionals. This study highlights the risk of an increased power asymmetry between patients and distributed emergency teams and can serve as a basis for further research, education, and quality improvement.
