BackgroundThis study follows published associations in BC to 2014 (updated in 2019) to model the predicted incidence of asthma in BC children attributable to antibiotic use within the context of reduced antibiotic use and increased breastfeeding in BC infants from 2000 to 2019.MethodsA population-based ecological study was conducted in BC from 2000 to 2019, using outpatient antibiotic prescription data from BC PharmaNet and asthma diagnoses from the Chronic Disease Registry. Breastfeeding estimates were calculated using the Canadian Community Health Survey (CCHS). Population attributable risk (PAR) was calculated using a blended relative risk (RR) of asthma in antibiotic-exposed children who were and were not breastfed. PAR was used to calculate predicted vs. actual asthma incidence in 2019. Negative binomial regression was used to estimate the association between the average antibiotic prescription rate in infants under 1 and asthma incidence in 1–4 year olds, stratified by periods between 2000–2014 and 2015–2019.ResultsIn BC, antibiotic prescribing decreased by 77% in infants under 1 and asthma incidence decreased by 41% in children 1–4 years from 2000 to 2019. BC breastfeeding rates increased from 46% in the 2005 CCHS to 71% in the 2017/18 CCHS. After calculating the PAR using a blended RR, the predicted asthma incidence in 2019 was 18.8/1,000 population. This was comparable to the observed asthma incidence in children 1–4 years of 16.6/1,000 population in 2019. During 2000–2014, adjusted incidence risk ratio (aIRR) for children under Quintile 5 of average antibiotic prescribing was 1.75 (95% CI: 1.63–1.88, P

BackgroundAntitumoral immune response has a crucial role in constraining cancer. However, previous studies on cholangiocarcinoma (CCA), a rare and aggressive cancer, have reported contradictory findings on the prognostic impact of tumor-infiltrating T-lymphocytes. We aimed to clarify the effect of tumor-infiltrating CD3+ and CD8+ lymphocytes and PD-1/PD-L1 expression on CCA prognosis.MethodsCD3+, CD8+, and PD-1+ lymphocyte densities, as well as PD-L1 expression rate were analyzed from stained tissue microarray samples from the tumor center and invasive margin of 47 cholangiocarcinomas. The association of CD3+ and CD8+ based Immune cell score (ICS) and its components with overall survival was evaluated, adjusting for age, sex, TNM stage, radicality of surgery, tumor location, and PD-L1 expression on immune cells.ResultsLow ICS was a strong independent prognostic factor for worse overall survival (Hazard ratio 9.27, 95% confidence interval 2.72-31.64, P

Patients’ expectations are a major contributor to the unnecessary prescribing of antibiotics, yet limited research has examined how physicians can calibrate these expectations. The studies we conducted tested how varying messages could impact patients’ expectations for antibiotics and their experience of medical appointments. All the participants read a short scenario about an appointment for mild sinusitis symptoms, with the patient’s expectation of antibiotics. In Study 1, the participants (n = 1069) were randomly assigned to read a positively framed, neutral, or negatively framed message regarding unnecessary antibiotics. In Study 2, the participants (n = 1073) read a message emphasizing either the societal or personal harms of unnecessary antibiotics, or a message without additional rationale. None of our pre-registered hypotheses were supported, but our exploratory analyses indicated that the societal message increased concern about antibiotic resistance. The participants who were more concerned about resistance were less likely to ask for antibiotics, more satisfied when the physician did not prescribe them, and more likely to recommend the physician to a friend. Discussing the consequences of the different courses of action did not appear to negatively impact physician–patient rapport. These studies demonstrate an inexpensive method with which to pre-test various messages about antibiotic consumption, and suggest that such messages are not negatively received by patients.

Lymphomatoid papulosis (LyP) is a benign chronic often relapsing skin condition that belongs to the CD30‐positive cutaneous lymphoproliferative disorders. LyP typically presents as crops of lesions with a tendency to self‐resolve, and morphology can range from solitary to agminated or diffuse papules and plaques to nodules or tumours. The clinical–histological spectrum can range from borderline cases to overlap with primary cutaneous anaplastic cell lymphoma (pcALCL). Histology and immunophenotype commonly show overlap with other CD30‐positive disorders and sometimes may be identical to pcALCL, making its diagnosis more difficult. Patients with LyP have an increased risk of developing a second neoplasm such as mycosis fungoides, pcALCL and/or Hodgkin lymphoma. Clinical correlation allows its proper classification and diagnosis, which is fundamental for treatment and prognosis. This review focuses on the clinical appearance, histopathological features, diagnosis, differential diagnosis and management of LyP. [ABSTRACT FROM AUTHOR]

Photonic crystal fibers guide light by trapping it in a periodic array of elements in the cladding area. We fabricated photonic crystal fibers by multiple extrusions of silver halide (AgClxBr1-x) crystals which are highly transparent in the middle infrared. The core of such a fiber consisted of pure silver bromide AgBr (n=2.16 at 10.6 μm), and the cladding area consisted of concentric rings of fiber-optic elements made of pure silver chloride AgCl (n=1.98 at 10.6 μm), which lowered the refractive index of the clad. Two types of photonic crystal fibers were fabricated, one with two concentric rings and one with five concentric rings of fiber-optic elements around the core. The characterization of the fibers, such as the power distribution, the attenuation, and the numerical aperture were measured. Both fibers behaved like regular core-clad structures. Simulations on these structures showed that each of these fibers guided a small number of modes and that adding rings to the structure lowered the number of bound modes in the core. This would pave the way for the fabrication of single-mode fibers. Photonic crystal fibers offer many advantages compared to conventional fibers, and they will be extremely useful for many applications in the middle and far infrared. [ABSTRACT FROM AUTHOR]

Objectives: Older adults face racism, sexism, and ageism. As the U.S. population ages, it is important to understand how the current population views older adults. Methods: Participants recruited through Amazon's Mechanical Turk provided perceptions of older Black and White models' photographs. Using mixed-effect models, we assessed interactions between race and gender of participants and models. Results: Among Participants of Color and White participants (n?=?712, 70% non-Hispanic White, 70% women, mean 37.81 years), Black models were perceived as more attractive, less threatening, and sadder than White models, but differences were greater for White participants (race-by-race interaction: attractive p?=?0.003, threatening p?=?0.009, sad p?=?0.016). Each gender perceived their respective gender as more attractive (gender-by-gender interaction p?0.0001). Male and female participants perceived male models as happier than female models, but differences were greater for male participants (p?=?0.026). Irrespective of participant age group, women were perceived as more threatening (p?=?0.012). Other perceptions were not significant. Discussion: Participants had few biases toward older Black and White models, while gender biases favored men.

Abstract Background Previous research on health behavior and subjective well-being has mainly focused on interindividual differences or explored certain domains of health behavior. Good health behavior and subjective well-being at baseline can predict each other after a follow-up. In the present cohort study, we explored the outcomes of change for an individual i.e., how changed health behavior is reflected in subsequent subjective well-being and vice versa. Methods Data (n = 10,855) originates from a population-based Health and Social Support (HeSSup) study on working-age Finns in 2003 and 2012. A composite measure of health behavior included physical activity, dietary habits, alcohol consumption, and smoking status (range 0–4, worst–best) and a composite measure of subjective well-being (with reversed scoring) included three life assessments, i.e., interest, happiness, and ease in life, and perceived loneliness (range 4–20, best–worst). Different multiple linear regression models were used to study how changes in health behavior predict subjective well-being and the opposite, how changes in subjective well-being predict health behavior. Results A positive change in health behavior from 2003 to 2012 predicted better subjective well-being (i.e., on average 0.31 points lower subjective well-being sum score), whereas a negative change predicted poorer subjective well-being (i.e., 0.37 points higher subjective well-being sum score) (both: p

Repeated cocaine exposure produces an enhanced locomotor response (sensitization) paralleled by biological adaptations in the brain. Previous studies demonstrated region-specific responsivity of adenosine monophosphate-activated protein kinase (AMPK) to repeated cocaine exposure. AMPK maintains cellular energy homeostasis at the organismal and cellular levels. Here, our objective was to quantify changes in phosphorylated (active) and total AMPK in the cytosol and synaptosome of the medial prefrontal cortex, nucleus accumbens, and dorsal striatum following acute or sensitizing cocaine injections. Brain region and cellular compartment selective changes in AMPK and pAMPK were found with some differences associated with acute withdrawal versus ongoing cocaine treatment. Our additional goal was to determine the behavioral and molecular effects of pretreatment with the indirect AMPK activator metformin. Metformin potentiated the locomotor activating effects of acute cocaine but blocked the development of sensitization. Sex differences largely obscured any protein-level treatment group effects, although pAMPK in the NAc shell cytosol was surprisingly reduced by metformin in rats receiving repeated cocaine. The rationale for these studies was to inform our understanding of AMPK activation dynamics in subcellular compartments and provide additional support for repurposing metformin for treating cocaine use disorder.

Abstract Background Previous studies have shown positive association between health behavior and life satisfaction, but the studies have mostly been cross-sectional, had follow-up times up to 5 years or focused on only one health behavior domain. The aim of the study was to explore how principal health behavior domains predict life satisfaction as a composite score in a previously unexplored longitudinal setting. Methods The present study tested whether a health behavior sum score (range 0–4) comprising of dietary habits, smoking, alcohol consumption, and physical activity predicted subsequent composite score of life satisfaction (range 4–20). Data included responses from 11,000 working-age Finns who participated in the Health and Social Support (HeSSup) prospective population-based postal survey. Results Protective health behavior in 2003 predicted (p

Previous research suggests that the characteristics of both patients and physicians can contribute to the overuse of antibiotics. Until now, patients’ psychosocial characteristics have not been widely explored as a potential contributor to the overuse of antibiotics. In this study, the relationship between a patient’s psychosocial characteristics (self-reported in postal surveys in 2003) and the number of antibiotics they were prescribed (recorded in Finnish national registry data between 2004–2006) were analyzed for 19,300 working-aged Finns. Psychosocial characteristics included life satisfaction, a sense of coherence, perceived stress, hostility, and optimism. In a structural equation model, patients’ adverse psychosocial characteristics were not related to increased antibiotic prescriptions in the subsequent three years. However, these characteristics were strongly associated with poor general health status, which in turn was associated with an increased number of subsequent antibiotic prescriptions. Furthermore, mediation analysis showed that individuals who used healthcare services more frequently also received more antibiotic prescriptions. The current study does not support the view that patients’ adverse psychosocial characteristics are related to an increased number of antibiotic prescriptions. This could encourage physicians to actively discuss treatment options with their patients.

Early-career female faculty, both physician scientists and basic researchers, have disproportionately experienced negative professional, financial, and personal consequences associated with the novel coronavirus disease 2019 (COVID-19) pandemic. This career phase represents a critical time for establishing a network of mentors and collaborators, demonstrating professional independence, and balancing new teaching, research, and service duties while simultaneously navigating personal and familial responsibilities. Persistent gender inequality perpetuated by adherence to traditional gender roles place early-career women faculty at a further disadvantage. Women in academic medicine and research do not attain promotion, leadership positions, and other established markers of success at the same rate as their male counterparts. This disparity was the impetus for the creation of a Recruitment and Retention action group within the Center for Women in Medicine and Science (CWIMS) at the University of Minnesota Medical School (UMN). This perspective piece is written from the viewpoint of a group of female-identifying early-career faculty participating in a career development program for early-stage and newly appointed faculty at UMN, sponsored by the Recruitment and Retention CWIMS action group and our Office of Faculty Affairs. We describe areas of stress exacerbated by the COVID-19 pandemic: work, financial, and work-life well-being, and propose an adapted diversity, equity and inclusion (DEI) model to guide the response to future challenges within a faculty competency framework. We offer recommendations based on the DEI-competency framework, including opportunities for lasting positive change that can emerge from this challenging moment of our collective history.

The cross-sectional association between measures of subjective well-being (SWB) and various health behaviors is well-established. In this 9-year (2003–2012) follow-up study, we explored how a composite indicator of SWB (range 4–20) with four items (interest, happiness, and ease in life, as well as perceived loneliness) predicts a composite health behavior measure (range 0–4) including dietary habits, physical activity, alcohol consumption, and smoking status. Study subjects (n = 10,855) originated from a population-based random sample of working-age Finns in the Health and Social Support study (HeSSup). According to linear regression analysis, better SWB predicted better health behavior sum score with a β = 0.019 (p

Background The bidirectional relationship between health behavior and subjective well-being has previously been studied sparsely, and mainly for individual health behaviors and regression models. In the present study, we deepen this knowledge focusing on the four principal health behaviors and using structural equation modeling with selected covariates. Methods The follow-up data (n = 11,804) was derived from a population-based random sample of working-age Finns from two waves (2003 and 2012) of the Health and Social Support (HeSSup) postal survey. Structural equation modeling was used to study the cross-sectional, cross-lagged, and longitudinal relationships between the four principal health behaviors and subjective well-being at baseline and after the nine-year follow-up adjusted for age, gender, education, and self-reported diseases. The included health behaviors were physical activity, dietary habits, alcohol consumption, and smoking status. Subjective well-being was measured through four items comprising happiness, interest, and ease in life, and perceived loneliness. Results Bidirectionally, only health behavior in 2003 predicted subjective well-being in 2012, whereas subjective well-being in 2003 did not predict health behavior in 2012. In addition, the cross-sectional interactions in 2003 and in 2012 between health behavior and subjective well-being were statistically significant. The baseline levels predicted their respective follow-up levels, the effect being stronger in health behavior than in subjective well-being. Conclusion The four principal health behaviors together predict subsequent subjective well-being after an extensive follow-up. Although not particularly strong, the results could still be used for motivation for health behavior change, because of the beneficial effects of health behavior on subjective well-being.

As part of a project to construct virus-resistant transgenic grapevines, grapevine virus A (GVA) coat protein (CP) sequences were introduced into grapevine and the model plant Nicotiana benthamiana. The engineered constructs were tested for their ability to engender resistance in N. benthamiana. A number of GVA-CP-transformed N. benthamiana lines have become resistant to GVA. Preliminary biological and molecular analyses strongly suggest that in most cases the obtained resistance is RNA-mediated. Several lines of transgenic grapevine were obtained. [ABSTRACT FROM AUTHOR]

Background Race influences medical decision making, but its impact on advanced heart failure therapy allocation is unknown. We sought to determine whether patient race influences allocation of advanced heart failure therapies. Methods and Results Members of a national heart failure organization were randomized to clinical vignettes that varied by patient race (black or white man) and were blinded to study objectives. Participants (N=422) completed Likert scale surveys rating factors for advanced therapy allocation and think‐aloud interviews (n=44). Survey results were analyzed by least absolute shrinkage and selection operator and multivariable regression to identify factors influencing advanced therapy allocation, including interactions with vignette race and participant demographics. Interviews were analyzed using grounded theory. Surveys revealed no differences in overall racial ratings for advanced therapies. Least absolute shrinkage and selection operator regression selected no interactions between vignette race and clinical factors as important in allocation. However, interactions between participants aged ≥40 years and black vignette negatively influenced heart transplant allocation modestly (−0.58; 95% CI, −1.15 to −0.0002), with adherence and social history the most influential factors. Interviews revealed sequential decision making: forming overall impression, identifying urgency, evaluating prior care appropriateness, anticipating challenges, and evaluating trust while making recommendations. Race influenced each step: avoiding discussing race, believing photographs may contribute to racial bias, believing the black man was sicker compared with the white man, developing greater concern for trust and adherence with the black man, and ultimately offering the white man transplantation and the black man ventricular assist device implantation. Conclusions Black race modestly influenced decision making for heart transplant, particularly during conversations. Because advanced therapy selection meetings are conversations rather than surveys, allocation may be vulnerable to racial bias.

Service learning is a community engagement pedagogy often used in the context of the undergraduate classroom to synergize course-learning objectives with community needs. We find that an effective way to catalyze student engagement in service learning is for student participation to occur outside the context of a graded course, driven by students’ own interests and initiative. In this paper, we describe the creation and implementation of a self-driven service learning program and discuss its benefits from the community, student, and faculty points of view. This experience allows students to explore careers in the sciences as well as identify skill strengths and weaknesses in an environment where mentoring is available but where student initiative and self-motivation are the driving forces behind the project’s success. Self-driven service learning introduces young scientists to the idea that their careers serve a larger community that benefits not only from their discoveries but also from effective communication about how these discoveries are relevant to everyday life.

Objective: To evaluate implementation of a patient decision aid for symptomatic uterine fibroid management to improve shared decision-making at five clinical settings across the United States., Methods: We used a type 3 hybrid effectiveness-implementation stepped-wedge design and the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) planning and evaluation framework. We conducted clinician training, monthly reach tracking with feedback to site clinical leads, patient and clinician surveys, and visit audio-recordings. Implementation strategies included assessment of organizational readiness for shared decision-making, synchronous clinician training, audit and feedback of decision aid reach, and access to multiple decision aid formats. Outcomes and analyses included patient-level reach, clinician-level adoption, and associations of patient-reported decision aid exposure (as treated) and setting-level implementation (intention-to-treat) with patient-reported (collaboRATE measure) and observed (OPTION-5 measure) shared decision-making. We also designed and assessed setting-level plans for sustainability and other factors impacting sustained decision aid use., Results: The decision aid was adopted by 72 of the 74 eligible gynecologists (97%) and reached 2553 patients across five settings. CollaboRATE scores improved among patients who reported receiving the decision aid (as-treated analysis, 69% vs. 59%; OR 1.6, 95% CI 1.16-2.27). CollaboRATE scores remained consistent before and after setting-level decision aid implementation (intention-to-treat analysis, 64% vs. 63%; OR 0.86, 95% CI 0.61-1.22). Participants would prefer to receive a decision aid at multiple time points (91.9% before the visit, 90.7% during the visit, 86.5% after the visit). Shared decision-making experiences did not improve when comparing pre vs. post-implementation collaboRATE scores across included settings (intention-to-treat, 64% vs. 63%; OR 0.86, 95% CI 0.61-1.22)., Conclusion: When patients with symptomatic uterine fibroids are given decision aids, they report higher shared decision-making scores. However, the differences we observed between the as-treated and intention-to-treat results suggest that unaddressed implementation challenges continue to limit the extent to which patients receive decision aids and likely hinder their overall impact. Future efforts to implement decision aids should explore enhancing their integration into clinical workflows and standard operating procedures, supported by organizational incentives that prioritize shared decision-making., Trial Registration: ClinicalTrials.gov NCT03985449; registered 6 June 2019., (© 2024.

Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time., Purpose: Pharmacy transitions of care (ToC) programs have been shown to decrease 30-day hospital readmissions and improve patient outcomes, but there is limited published data on the impact of pharmacist-integrated ToC services beyond 30 days. The objective of this study was to evaluate the impact of pharmacist-integrated ToC and population health services on 30-, 60-, and 90-day all-cause readmissions in a Medicare value-based program (MV-BP) population and to compare mean times to first readmission with and without pharmacist care., Methods: A retrospective observational chart review was conducted to identify eligible hospital discharge encounters (DEs). Patients 18 years of age or older enrolled in an MV-BP were assigned to 4 study groups (a control group or one of 3 intervention arms) based on the pharmacy ToC services they received from either an inpatient ToC pharmacist or a dedicated population health pharmacist (PHP)., Results: Among 1,065 eligible DEs, 90-day follow-up was completed in 1,039 cases. The control group (n = 213) had a 90-day readmission rate of 34.74%. Intervention arm 1 (n = 201) had no significant reduction in 90-day readmissions, with a rate of 29.85% (odds ratio [OR], 0.94; 95% CI, 0.61-1.47; P = 0.80), while intervention arms 2 (n = 209), and 3 (n = 416) had significantly lower rates of readmission: 9.57% (OR, 0.26; 95% CI, 0.15-0.46; P < 0.01), and 17.07% (OR, 0.41; 95% CI, 0.27-0.61; P < 0.01), respectively., Conclusion: A combination of ToC and PHP services reduced 30-, 60-, and 90-day readmission rates in an MV-BP population. These results support the expansion of pharmacy-based ToC to minimize readmissions within 90 days for this Medicare population., (© American Society of Health-System Pharmacists 2024.

Vulvar and vaginal melanomas (VVMs) are rare and aggressive malignancies with limited prognostic models available and there is no standard reporting protocol. VVMs were selected from six tertiary Canadian hospitals from 2000-2021, resected from patients aged ≥18 years, with 6 months or longer follow-up data, and confirmation of melanocytic differentiation by at least two immunohistochemical markers. Cases were reviewed by pathologists to identify histological biomarkers. Survival outcomes were tested with Kaplan-Meier log-rank, univariate Cox, and multivariate Cox regression. There were 79 VVMs with median follow-up at 26 months. Univariate analysis revealed that tumour necrosis, tumour ulceration, positive lymph nodes, and metastasis at diagnosis were significantly associated with disease-specific mortality, progression, and metastasis. Multivariate analysis identified tumour necrosis as an independent prognostic factor for disease-specific mortality (HR 4.803, 95% CI 1.954-11.803, p<0.001), progression (HR 2.676, 95% CI 1.403-5.102, p=0.003), and time-to-metastasis for non-metastatic patients at diagnosis (HR 3.761, 95%CI 1.678-8.431, p=0.001). Kaplan-Meier survival analyses demonstrated that tumour necrosis was a poor prognostic factor for disease-specific, progression-free, and metastasis-free survival (p<0.001 for all comparisons). Vaginal melanomas displayed decreased survival compared to vulvar or clitoral melanomas. This study identifies tumour necrosis as an independent prognostic factor for VVMs. Vaginal melanomas specifically showed worse survival outcomes compared to vulvar or clitoral melanomas, consistent with previously reported findings in the literature, emphasising the importance of differentiating between these primary tumour epicentres for prognostication and treatment planning in the care of genital melanoma patients., (Copyright © 2024 Royal College of Pathologists of Australasia.

Background: Minoritized communities in the United States have had higher COVID-19 mortality and lower vaccine uptake. The influence of previous SARS-CoV-2 infection, initial disease severity, and persistent symptoms on COVID-19 vaccine uptake in Black and Latinx communities has not been examined., Objective: To investigate whether initial COVID-19 severity, persistent symptoms, and other correlates affected vaccine uptake in a predominantly minoritized cohort hospitalized for COVID-19 during the early pandemic in New York City., Design: In this historical cohort study, we abstracted electronic health record data on demographics, comorbidities, hospital oxygen requirements, symptoms at 3 and 6 months post-admission, COVID-19 vaccinations through November 2022, and influenza vaccinations during the 2018-2019 through 2021-2022 seasons. Unadjusted and adjusted odds ratios were estimated through logistic regression analyses of correlates of COVID-19 vaccination, on-time vaccination, and boosting., Participants: Survivors among the first 1186 adult patients hospitalized for COVID-19 between March 1 and April 8, 2020 at a large quaternary care medical center in Northern Manhattan., Main Measures: Uptake of at least one COVID-19 vaccine dose, uptake of at least one booster, and on-time vaccination., Key Results: The 890 surviving individuals were predominantly Latinx (54%) and Non-Hispanic Black (15%). Most had one or more comorbidities (67%), and received at least one COVID-19 vaccine dose (78%). Among those vaccinated, 57% received at least one booster, and 31% delayed vaccination. 67% experienced persistent symptoms. Multiple logistic regression showed no association between vaccine uptake and disease severity or symptom persistence. However, older age and influenza vaccination during the COVID-19 era were associated with increased vaccination, booster uptake, and on-time vaccination., Conclusions: Pinpointing drivers of vaccine uptake and hesitancy is critical to increasing and sustaining COVID-19 vaccination as the field transitions to annual boosters. The association between influenza vaccination and increased vaccine uptake suggests that bundling vaccines for adults may be an effective delivery strategy., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Delivette Castor and Magdalena Sobieszczyk report financial support was provided by Gilead Sciences, Inc.

Introduction: Rectal bleeding commonly occurs in elderly patients using blood thinners, posing management challenges due to limited guidance on reversal agents and medication restart criteria. This study aims to review the demographics and management of elderly patients with rectal bleeding while on blood thinners., Methods: A retrospective analysis of patients aged 60 or older presenting with rectal bleeding at West Suffolk Hospital's emergency department was conducted from January 2018 to December 2020. Data were extracted from electronic records, focusing on patients using blood thinners and adhering to British Society of Gastroenterology guidelines. All patients ceased blood-thinning medications upon admission. The hospital's ethics committee approved the study, which focused on demographics, diagnosis, and management, particularly regarding re-initiation of blood-thinning medicines., Results: During the study period, 170 patients were admitted to the emergency department of West Suffolk Hospital. 93 (54.71%) patients were included in the study. The average age of the participants was 82 years, and 62.3% were male. All patients were followed up for three months. Atrial fibrillation accounted for 52% of patients, while previous strokes accounted for 20%. The most typical pathology was diverticulosis.Regarding restarting of anticoagulants, Among patients on DOAC (Direct oral anticoagulant), 39% were restarted on discharge, 23% were switched to warfarin, and another 23% were not restarted; 15% planned to restart after seven days. For those on Warfarin, 62% were restarted on discharge, 22% stopped the medication, and the rest were switched to Dual Oral Anticoagulant. Among aspirin patients, 60% were restarted at discharge, while the remaining discontinued. All patients receiving clopidogrel and dual antiplatelet therapy were started at discharge. None of the patients were readmitted during the follow-up period of 3 months., Conclusion: Restarting of blood-thinning drugs in patients with rectal bleeding is subject to individual patient variation. Necessitates more extensive trials to achieve greater standardization., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Bavikatte A et al.)

Background: Sports and physical activity are known risk factors for pelvic floor dysfunction (PFD). The aim of this study is to examine the impact of amateur running on PFD, quality of life (QoL), and sexual function., Methods: Amateur runners were contacted through social media. Their PFD, sexual function, and QoL were evaluated by self-reporting validated questionnaires (PFDI-20, PISQ-12, IIQ-7). They were divided by degree of effort into two categories, 'High effort' and 'Moderate effort'. The differences between the two groups were examined by a Mann-Whitney U Test, T-Test, and Chi-square test., Results: 180 women were included. A high incidence of PFD was found among 'High effort' runners in comparison to 'Moderate effort' runners. In addition, women who scored above the median in the PFDI-20 showed significantly greater impairment in QoL and sexual function. Interestingly, the 'High effort' group reported experiencing higher intensity orgasms compared with women in the 'Moderate effort' group. A correlation was also found between the weekly running distance and the intensity of orgasm experienced (P value = 0.004)., Conclusion: 'High effort' runners present a higher incidence of PFD in comparison to 'Moderate effort' runners. Professional pelvic floor muscle training counselling should be considered even for amateur runners. Future interventional physical therapy studies should be carried out in order to investigate preventative strategies., (© 2024.

Objectives: To assess whether advanced age is a risk factor for complications following pelvic organ prolapse (POP) repair surgeries using the Clavien-Dindo classification system., Methods: In this retrospective cohort study, 260 women who had undergone POP repair surgery at the Soroka University Medical Center (SUMC) between the years 2014-2019 were included. A univariate analysis was conducted to compare the demographical, clinical, obstetrical and operative characteristics of patients by age group (younger or older than 70 years). We performed a similar analysis to assess for the possible association between several variables and post-operative complications. Variables that were found to be associated with post-operative complications (P < 0.2) were included in a multivariate analysis along with advanced age., Results: During the 12 months follow-up period, more than half of the women had experienced at least one post-operative complication. Minor complications (grades 1-2 according to the Clavian-Dindo classification system) were the most common. One woman had died during the follow-up period, and none had experienced organ failure (grade 4). Hysterectomy, as part of POP surgery, was found to be significantly associated with post-operative complications. Additionally, grandmultiparity (> 5 births) showed a tendency towards an increased risk for post-operative complications, however this reached only borderline significance. We found no association between advanced age and post-operative complications., Conclusions: POP repair surgeries are safe for women of all ages. Major complications (grades 3-5) are rare in all age groups. Although advanced age was associated with a higher prevalence of comorbidity and a higher grade of prolapse, no significant difference in the post-operative complications was found between age groups. Concomitant hysterectomy at the time of POP repair surgery is a risk factor for post-operative complications., (© 2024.

Background: Abuse of healthcare workers (HCWs) and lack of public trust threaten the foundation of the physician-patient relationship. This growing global problem creates an even more difficult professional environment and hinders the delivery of high-quality clinical care., Objective: The primary aim was to determine the prevalence of violence against Trinbagonian HCWs in the public sector. Secondary objectives included determining risk factors for violence and mistrust between the public and providers., Method: A cross-sectional analysis of 434 HCWs in the public sector of Trinidad and Tobago was conducted using a modified World Health Organization (WHO) data collection tool, distributed via social media and administrative emails, and snowballed for two months. Fifteen semi-structured interviews were conducted regarding trust in the healthcare system with patients selected from communities., Results: Of the 434 respondents, 45.2% experienced violence and 75.8% witnessed violence against HCWs in the past two years. Verbal abuse (41.5%) was most common. Perpetrators were patients (42.2%) and patients' relatives (35.5%). Chi-square analysis highlighted that HCWs with the highest probability of being abused were aged 25-39 (63.8%), had two to five years of work experience (24.9%), specialized in emergency and internal medicine (48.6%), and cared for psychiatric and physically disabled patients (p-value < 0.001). HCWs believed the threat of violence negatively impacted performance (64.5%), and further action was necessary for mitigation (86.4%). Patients interviewed doubted physicians' altruism and competence (80%) and honesty (53.3%), expressed mistrust in their physician (46.7%), and cited poor infrastructure/management (66.7%) and dissatisfaction with care (60.0%) as factors that contributed to violence., Conclusion: Analysis revealed that violence against Trinbagonian HCWs in the public sector deteriorated patient experience and adversely affected psychological well-being, efficiency, and job satisfaction. Results suggested mistrust of HCWs by the population. Interventions should be instituted to support at-risk HCWs and educate the public to avoid recurrence., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Dookeeram et al.)

Objective: To inquire whether obesity is a risk factor of peri- and post-operative complications following Mid-urethral sling (MUS) surgeries for SUI repair using the Clavien-Dindo classification system (CDcs)., Methods: This retrospective cohort included 304 women who undergone a MUS in a 1000 beds tertiary University medical center between the years 2012-2018. Univariate analysis was conducted to compare clinical and operative traits by BMI group and to examine associations of obesity and complications rates and severity according to the CDcs. Multivariate analysis was conducted to assess the risk for post-operative complications and adjust to potential confounders., Results: The study group included 106 (34.9%) women with BMI 30 or higher and the comparison group included 198 (65.1%) women with BMI lower than 30. In the study group we found a significantly higher prevalence of hypertension (P = 0.019), previous abdominal surgeries (P = 0.012) including cesarean section (P = 0.025), previous pelvic floor surgeries (P = 0.005) and pelvic organ prolapse (P = 0.02). In the control group we found a significantly higher rates of concomitant hysterectomy which performed during the MUS (P = 0.005). Obesity was not associated with increased rates of peri and post-operative complications (P = 0.973)., Conclusions: In our study, obesity was not associated with peri- and post-operative complications following MUS., (© 2023.

Background: Recent cases of clinical failure in malaria patients in the United Kingdom (UK) treated with artemether-lumefantrine have implications for malaria chemotherapy worldwide., Methods: Parasites were isolated from an index case of confirmed Plasmodium falciparum treatment failure after standard treatment, and from comparable travel-acquired UK malaria cases. Drug susceptibility in vitro and genotypes at 6 resistance-associated loci were determined for all parasite isolates and compared with clinical outcomes for each parasite donor., Results: A traveler, who returned to the UK from Uganda in 2022 with Plasmodium falciparum malaria, twice failed treatment with full courses of artemether-lumefantrine. Parasites from the patient exhibited significantly reduced susceptibility to artemisinin (ring-stage survival, 17.3% [95% confidence interval {CI}, 13.6%-21.1%]; P < .0001) and lumefantrine (effective concentration preventing 50% of growth = 259.4 nM [95% CI, 130.6-388.2 nM]; P = .001). Parasite genotyping identified an allele of pfk13 encoding both the A675V variant in the Pfk13 propeller domain and a novel L145V nonpropeller variant. In vitro susceptibility testing of 6 other P. falciparum lines of Ugandan origin identified reduced susceptibility to artemisinin and lumefantrine in 1 additional line, also from a 2022 treatment failure case. These parasites did not harbor a pfk13 propeller domain variant but rather the novel nonpropeller variant T349I. Variant alleles of pfubp1, pfap2mu, and pfcoronin were also identified among the 7 parasite lines., Conclusions: We confirm, in a documented case of artemether-lumefantrine treatment failure imported from Uganda, the presence of pfk13 mutations encoding L145V and A675V. Parasites with reduced susceptibility to both artemisinin and lumefantrine may be emerging in Uganda., Competing Interests: Potential conflicts of interest. B. C.

Purpose: The aim of this study was to utilize an intersectional framework to examine academic faculty's lived experiences during COVID-19. Specifically, we set out to: (1) describe the multiple intersectional identities ( e.g. , gender, race/ethnicity, rank, caregiver status, disability status) represented by the faculty, (2) examine potential disparities in well-being, workload, and productivity linked to these intersectional factors, and (3) identify qualitative themes endorsed by faculty as they relate to lived experiences during COVID-19. Methods: This was a cross-sectional mixed-methods research study. The Center for Women in Medicine and Science (CWIMS) at the University of Minnesota developed and implemented a survey between February-June of 2021 in response to national reports of disparities in the impacts of COVID-19 on faculty with lived experiences from multiple intersections. Results: There were 291 full-time faculty who participated in the study. Quantitative findings indicated that faculty with multiple intersectional identities ( e.g. , woman+assistant professor+caregiver+underrepresented in medicine) reported greater depression symptoms, work/family conflict, and stress in contrast to faculty with fewer intersectional identities. Furthermore, faculty with more intersectional identities reported higher clinical workloads and service responsibilities and lower productivity with regard to research article submissions, publications, and grant submissions in contrast to faculty with fewer intersectional identities. Qualitative findings supported quantitative findings and broadened understanding of potential underlying reasons. Conclusions: Findings confirm anecdotal evidence that faculty with lived experiences from multiple intersections may be disproportionately experiencing negative outcomes from the pandemic. These findings can inform decisions about how to address these disparities moving into the next several years with regard to promotion and tenure, burnout and well-being, and faculty retention in academic medical settings. Given these findings, it is also important to intentionally plan responses for future public health crises to prevent continued disparities for faculty with multiple intersectional identities.

Repeated cocaine exposure produces an enhanced locomotor response (sensitization) paralleled by biological adaptations in the brain. Previous studies demonstrated region-specific responsivity of adenosine monophosphate-activated protein kinase (AMPK) to repeated cocaine exposure. AMPK maintains cellular energy homeostasis at the organismal and cellular levels. Here, our objective was to quantify changes in phosphorylated (active) and total AMPK in the cytosol and synaptosome of the medial prefrontal cortex, nucleus accumbens, and dorsal striatum following acute or sensitizing cocaine injections. Brain region and cellular compartment selective changes in AMPK and pAMPK were found with some differences associated with acute withdrawal versus ongoing cocaine treatment. Our additional goal was to determine the behavioral and molecular effects of pretreatment with the indirect AMPK activator metformin. Metformin potentiated the locomotor activating effects of acute cocaine but blocked the development of sensitization. Sex differences largely obscured any protein-level treatment group effects, although pAMPK in the NAc shell cytosol was surprisingly reduced by metformin in rats receiving repeated cocaine. The rationale for these studies was to inform our understanding of AMPK activation dynamics in subcellular compartments and provide additional support for repurposing metformin for treating cocaine use disorder.

This paper describes a patient with an inoperable gastrointestinal stromal tumour with moderate volume malignant ascites. A large-volume paracentesis caused haemodynamic instability and a myocardial infarction. An indwelling right-sided peritoneal catheter was inserted following further ascites build-up. The patient experienced spontaneous acute rupture of tumour and subsequent loculated ascites. An additional second catheter was inserted to the left side of the abdomen following reaccumulation of ascites following liquefaction of cyst contents and successful one-off drainage on the left side of abdomen. This is the first case report of a patient with two indwelling catheters: we describe learning points pertaining to those as well as the rupture of gastrointestinal stromal tumours. Haemodynamic instability after paracentesis in malignant-related ascites has also not been described., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.
