Lung transplantation is a life-saving treatment for patients with end stage lung disease. There may be a higher incidence of lung cancer in lung transplant recipients, and these cancers tend to be diagnosed at a more advanced stage. There is very little data on the safety and efficacy of stereotactic body radiation therapy (SBRT) for lesions in the native lung in lung-transplant recipients.

Background: As measured via static stability tests, the PCL is the dominant restraint to posterior tibial translation while the posterolateral corner is the dominant restraint to external tibial rotation. However, these uniplanar static tests may not predict multiplanar instability. The reverse pivot shift is a dynamic examination maneuver that may identify complex knee instability.Questions/purposes: In this cadaver study, we asked whether (1) isolated sectioning or (2) combined sectioning of the PCL and posterolateral corner increased the magnitude of the reverse pivot shift and (3) the magnitude of the reverse pivot shift correlated with static external rotation or posterior drawer testing.Methods: In Group I, we sectioned the PCL followed by structures of the posterolateral corner. In Group II, we sectioned the posterolateral corner structures before sectioning the PCL. We performed posterior drawer, external rotation tests, and mechanized reverse pivot shift for each specimen under each condition and measured translations via navigation.Results: Isolated sectioning of the PCL or posterolateral corner had no effect on the reverse pivot shift. Conversely, combined sectioning of the PCL and posterolateral corner structures increased the magnitude of the reverse pivot shift. The magnitude of the reverse pivot shift correlated with the posterior drawer and external rotation tests.Conclusions: Combined sectioning of the PCL and posterolateral corner was required to cause an increase in the magnitude of the mechanized reverse pivot shift. The reverse pivot shift correlated with both static measures of stability.Clinical Relevance: Combined injury to the PCL and posterolateral corner should be considered in the presence of a positive reverse pivot shift.

The purpose of this study was to determine the femoral and tibial fixation sites that would result in the most isometric MCL reconstruction technique. Seven cadaveric knees were used in this study. A navigation system was utilized to determine graft isometry continuously from 0 masculine to 90 masculine. Five points on the medial side of the femur and four on the tibia were tested. A graft positioned in the center of the MCL femoral attachment (F(C)) and attached in the center of the superficial MCL attachment on the tibia led to the best isometry (2.7 +/- 1.1 mm). Movement of the origin superiorly only 4 mm (F(S)) led to graft excursion of greater than 10 mm (P < 0.01). MCL reconstruction performed with the origin of the MCL within the femoral footprint and the insertion in tibial footprint of the superficial MCL results in the least graft excursion when the knee is cycled between 0 masculine and 90 masculine. Although the MCL often heals without surgical intervention, surgical reconstruction is occasionally in Grade III MCL and combined ligamentous injuries to the knee. This study demonstrates the optimal position of the MCL reconstruction to reproduce the kinematics of the native knee. [ABSTRACT FROM AUTHOR]

Background: To our knowledge, there has been no prospective study on the results of arthroscopic repair of superior labrum-biceps anchor complex (SLAP) tears with use of modern techniques. The purpose of the present study was to prospectively evaluate the minimum two-year results for patients with type-II SLAP tears that were treated with arthroscopic suture anchor fixation.Methods: Forty-seven patients with symptomatic type-II SLAP tears were evaluated preoperatively and at least two years postoperatively with use of the American Shoulder and Elbow Surgeons (ASES) and L'Insalata outcomes instruments and physical examination. The study group included thirty-nine male and eight female patients with a mean age of thirty-six years; thirty-four of the forty-seven patients were athletes. Patients with rotator cuff tears requiring repair or concomitant shoulder instability were excluded.Results: At an average of 2.7 years, the median ASES and L'Insalata scores were 97 and 93, respectively, compared with baseline scores of 62 and 65 (p < 0.05). The median patient-reported satisfaction rating was 9 (of 10); forty-one patients (87%) rated the outcome as good or excellent. The median patient-reported satisfaction rating was significantly higher for patients with a discrete traumatic etiology than for those with an atraumatic etiology (9 compared with 7); however, there was no significant difference between these groups in terms of the ASES or L'Insalata outcome scores. Overall, twenty-five (74%) of the thirty-four athletes were able to return to their preinjury level of competition, whereas eleven (92%) of the twelve athletes who reported a discrete traumatic event were able to return to their previous level of competition. There were five complications, including four cases of refractory postoperative stiffness.Conclusions: Our findings indicate that favorable outcomes can be anticipated in the majority of patients after arthroscopic SLAP lesion repair. While only three of four patients overall may be capable of returning fully to their previous level of competition, patients with a distinct traumatic etiology have a greater likelihood of a successful return to sports.

Lesions of the superior labrum are complex and difficult to both diagnose and treat effectively. The clinical diagnosis is challenging due to the nonspecific history and physical examination. MRI has substantially improved our ability to detect SLAP tears, although experience is necessary to distinguish pathologic findings from normal anatomic variants. Treatment is determined by patient age, functional demands, and the type of lesion identified. [ABSTRACT FROM AUTHOR]

Background: Many patient-based knee-rating scales are available for the evaluation of athletic patients. However, there is little information on the measurement properties of these instruments and therefore no evidence to support the use of one questionnaire rather than another. The goal of the present study was to determine the reliability, validity, and responsiveness of four knee-rating scales commonly used for the evaluation of athletic patients: the Lysholm scale, the subjective components of the Cincinnati knee-rating system, the American Academy of Orthopaedic Surgeons sports knee-rating scale, and the Activities of Daily Living scale of the Knee Outcome Survey.Methods: All patients in the study had a disorder of the knee and were active in sports (a Tegner score of 4 points). Forty-one patients who had a knee disorder that had stabilized and who were not receiving treatment were administered all four questionnaires at baseline and again at a mean of 5.2 days (range, two to fourteen days) later to test reliability. Forty-two patients were administered the scales at baseline and at a minimum of three months after treatment to test responsiveness. The responses of 133 patients at baseline were studied to test construct validity.Results: The reliability was high for all scales, with the intraclass correlation coefficient ranging from 0.88 to 0.95. As for construct validity, the correlations among the knee scales ranged from 0.70 to 0.85 and those between the knee scales and the physical component scale of the Short Form-36 (SF-36) and the patient and clinician severity ratings ranged from 0.59 to 0.77. Responsiveness, measured with the standardized response mean, ranged from 0.8 for the Cincinnati knee-rating system to 1.1 for the Activities of Daily Living scale.Conclusions: All four scales satisfied our criteria for reliability, validity, and responsiveness, and all are acceptable for use in clinical research.

The effect of iliotibial band 'lateral sling' augmentation on long-term outcome in ACL reconstruction using free autogenous central-third patellar tendon was evaluated retrospectively. Eighty reconstructions were reviewed; the minimum followup was 2 years and the average was 4 years. Sixty percent of the procedures involved supplementation with a lateral sling. By both clinical evaluation and KT-1000 measurement, there were no differences in the results of patients with lateral sling augmentation and those without it. In addition, 40% of patients had chronic pain and/or swelling related to the lateral sling. We do not currently recommend the routine use of a lateral sling augmentation for ACL reconstruction using central-third patellar tendon. [ABSTRACT FROM AUTHOR]

Zinc oxide nanoparticles (ZnO-NPs) can enhance zinc bioavailability in plants, improving crop nutritional quality and addressing global zinc deficiency. This study aimed to investigate the effects of zinc oxide nanoparticles (ZnO-NPs), obtained by a green synthesis method, on the growth, yield parameters, and zinc content of rice plants. In the study, two different application strategies of ZnO-NPs on rice plants were evaluated, i.e., foliar spray and seed priming. To compare the effects of these application strategies, rice plants were treated with ZnO-NPs at two different concentrations, 25 mg/L and 50 mg/L. Effects of ZnO-NPs on plant growth (shoot and root length, fresh and dry mass), chlorophyll and carotenoid content, grain yield and zinc content were investigated. The results showed that both ZnO-NP application methods increased rice growth and yield, especially the combined method (seed priming + foliar spray) provided the highest efficiency. It was observed that seed zinc content was increased up to 10% by seed priming method and foliar spray application increased the zinc content up to 23% while the combination of seed priming and foliar spray increased zinc content up to 122%. In general, applications at 50 mg/L concentration increased more than 25 mg/L. These results indicate that ZnO-NPs can be an effective tool for zinc deficiency management in agricultural practices and can improve the yield and nutritional content of staple foods such as rice., Competing Interests: Declarations.

Introduction: Opioid-related events continue to claim lives in the United States at alarming rates. Naloxone-dispensing rates fall dramatically short of national expectations. Emergency registered nurses are uniquely poised to connect at-risk patients with naloxone resources. This study sought to (1) describe the emergency registered nurses' willingness to provide naloxone resources and (2) explore variables that may influence the nurse's willingness to provide resources., Methods: A cross-sectional, survey-based design was deployed using an online branch logic approach to include a national sample of emergency registered nurses. The Willingness to Provide, a validated questionnaire, measured the registered nurse's willingness to provide naloxone resources for patients at risk of opioid overdose. Eight variables were assessed for potential influence on willingness., Results: A total of 159 nurses from 32 states and the District of Columbia completed the online survey via the Research Electronic Data Capture platform. The results revealed a mean Willingness to Provide score of 38.64 indicating a willingness to provide naloxone resources. A statistically significant relationship was identified between the nurse's willingness and years of nursing experience (P = .001), knowledge (P = .015), desire (P = .001), and responsibility (P < .001)., Discussion: In this representative sample, emergency nurses are willing to provide naloxone resources; furthermore, results indicate that higher knowledge, desire, and responsibility scores increase the nurse's willingness to provide naloxone resources; with education and clear expectations, emergency nurses may be able to improve the connection of patients at risk of opioid overdose with naloxone, a potentially lifesaving connection., (Copyright © 2024 Emergency Nurses Association.

The widespread presence of microplastics in the environment has raised significant concerns regarding their potential impact on human and animal health. Among various microplastic types, polyethylene microplastics (PE-MPs) are particularly prevalent due to the extensive use in packaging and consumer products. Exploring the uncharted therapeutic potentials of naringin, this study delves into its mitigating effects on disruptions in kallikrein-3 levels, steroidal-thyroidal hormone balance, and antioxidant defense triggered by PE-MPs exposure, paving the way for novel interventions in environmental toxin-induced endocrine and oxidative stress disorders. Male Wistar rats (n = 24) were randomly grouped into four: Control, PE-MPs (1.5 mg/kg), PE-MPs + NAR (1.5 mg/kg PE-MPs + 100 mg/kg NAR), and NAR (100 mg/kg). Hormonal and antioxidant parameters were assessed after 28 days of exposure. PE-MPs exposure caused a significant increase(p < 0.005) in the level of kallikrein-3 (KLK-3) while it significantly reduces the levels of testosterone (TST), luteinizing hormone, thyroid stimulating hormone (TSH) and Free-triiodothyronine (fT3) and Total cholesterol (TChol) concentration. PE-MPs exposure also disrupted significantly (p < 0.005) antioxidant profile by down-regulating the activities of glutathione-S-transferase, catalase (CAT), superoxide dismutase (SOD) and reducing levels of glutathione (GSH) and ascorbic acid (AA) while concentration of malondialdehyde (MDA) levels were increased relative to control. However, the mitigating potentials of naringin on disruptions in hormonal and antioxidant profiles caused by PE-MPs exposure were demonstrated, as NAR normalized KLK-3, steroid, and thyroid hormone levels, cholesterol concentration, and enhanced antioxidant defense. This suggests that NAR is a promising protective agent against endocrine and oxidative damage induced by environmental contaminants such as microplastics., (© 2024. The Author(s).)

Purpose: To determine whether leading, commercially-available LLMs provide treatment recommendations concordant with evidenced-based clinical practice guidelines (CPGs) developed by the American Academy of Orthopedic Surgeons (AAOS)., Methods: All CPGs concerning the management of rotator cuff tears(n=33) and anterior cruciate ligament (ACL) injuries(n=15) were extracted from the AAOS. Treatment recommendations from Chat-generative pretrained transformer version-4 [ChatGPT-4; OpenAI], Gemini (Google), Mistral-7B (Mistral AI), and Claude-3 (Anthropic) were graded by two blinded physicians as being "concordant," "discordant," or "indeterminate" (i.e., neutral response without definitive recommendation) with respect to AAOS CPGs. The overall concordance between LLM and AAOS recommendations were quantified, while the comparative overall concordance of recommendations amongst the four LLMs was evaluated through the Fischer's-exact test., Results: Overall 135(70.3%) responses were concordant, 43(22.4%) indeterminate, and 14(7.3%) discordant. Inter-rater reliability for concordance classification was excellent (Kappa=0.92). Concordance with AAOS CPGs was most frequently observed with ChatGPT-4 (n=38, 79.2%), and least frequently with Mistral-7B (n=28,58.3%). Indeterminate recommendations were most frequently observed with Mistral-7B (n=17,35.4%) and least frequently with Claude-3 (n=8, 6.7%). Discordant recommendations were most frequently observed with Gemini (n=6,12.5%) and least frequently with ChatGPT-4 (n=1,2.1%). Overall, no statistically significant differences in concordant recommendations was observed across LLMs (p=0.12). Only 20 (10.4%) of all recommendations were transparent and provided references with full bibliographic details or links to specific peer-reviewed content to support recommendations., Conclusion: Among leading commercially-available LLMs, more than one-in-four recommendations concerning the evaluation and management of rotator cuff and ACL injuries do not reflect current evidenced-based CPGs. Although ChatGPT-4 demonstrated the highest performance, clinically significant rates of recommendations without concordance or supporting evidence were observed. Only 10% of responses by LLMs were transparent, precluding users from fully interpreting the sources from which recommendations were provided., Clinical Relevance: While leading LLMs generally provide recommendations concordant with CPGs, a substantial error-rate exists, and the proportion of recommendations that do not align with these CPGs suggest that LLMs are not trustworthy clinical support tools at this time. Each off-the-shelf, closed-source LLM has strengths and weaknesses. Future research should evaluate and compare multiple LLMs to avoid bias associated with narrow evaluation of few models as observed in current literature., (Copyright © 2024.

Developing bioequivalent (BE) generic products of complex dosage forms like intravitreal implants (IVIs) of corticosteroids such as dexamethasone prepared using hot-melt extrusion (HME), based on biodegradable poly (lactide-co-glycolide) (PLGA) polymers, can be challenging. A better understanding of the relationship between the physicochemical and physicomechanical properties of IVIs and their effect on drug release and ocular bioavailability is crucial to develop novel BE approaches. It is possible that the key physicochemical and physicomechanical properties of IVIs such as drug properties, implant surface roughness, mechanical strength and toughness, and implant erosion could vary for different compositions, resulting in changes in drug release. Therefore, this study investigated the hypothesis that biodegradable ophthalmic dexamethasone-loaded implants with 20% drug and 80% PLGA polymer(s) prepared using single-pass hot-melt extrusion (HME) differ in physicochemical and/or physicomechanical properties and drug release depending on their PLGA polymer composition. Acid end-capped PLGA was mixed with an ester end-capped PLGA to make three formulations: HME-1, HME-2, and HME-3, containing 100%, 80%, and 60% w / w of the acid end-capped PLGA. Further, this study compared the drug release between independent batches of each composition. In vitro release tests (IVRTs) indicated that HME-1 implants can be readily distinguished by their release profiles from HME-2 and HME-3, with the release being similar for HME-2 and HME-3. In the early stages, drug release generally correlated well with polymer composition and implant properties, with the release increasing with PLGA acid content (for day-1 release, R 2 = 0.80) and/or elevated surface roughness (for day-1 and day-14 release, R 2 ≥ 0.82). Further, implant mechanical strength and toughness correlated inversely with PLGA acid content and day-1 drug release. Drug release from independent batches was similar for each composition. The findings of this project could be helpful for developing generic PLGA polymer-based ocular implant products.

Insomnia, the most prevalent sleep disorder, is commonly associated with other mental and somatic disorders, making it a significant health concern. It is characterized by nighttime symptoms and daytime dysfunction, with sleepiness being a potential criterion for the latter. Sleepiness is a normal physiological state that is typically experienced near usual bedtime, in normal circumstances. In insomnia, it seems somewhat logical the idea that there is significant daytime sleepiness. However, the topic has been the subject of various discussions in sleep medicine, with studies yielding contradictory and inconsistent results. In this article, we aim to critically examine daytime sleepiness in individuals with insomnia disorder and propose an alternative approach to addressing it, both in clinical practice and research settings. It is crucial to further investigate the role of daytime sleepiness in insomnia, particularly by focusing on sleepiness perception as a more relevant dimension to explore in majority of patients. It is plausible that certain insomnia phenotypes are objectively sleepy during the day, but more studies are necessary, particularly with well-defined clinical samples. The implications of assessing sleepiness perception in insomnia for clinical practice are discussed, and new avenues for research are suggested.

Background: Primary anterior cruciate ligament (ACL) repair has gained renewed interest in select centers for patients with proximal or midsubstance ACL tears. Therefore, it is important to reassess contemporary clinical outcomes of ACL repair to determine whether a clinical benefit exists over the gold standard of ACL reconstruction (ACLR)., Purpose: To (1) perform a meta-analysis of comparative trials to determine whether differences in clinical outcomes and adverse events exist between ACL repair versus ACLR and (2) synthesize the midterm outcomes of available trials., Study Design: Systematic review; Level of evidence, 3., Methods: The PubMed, OVID/Medline, and Cochrane databases were queried in August 2023 for prospective and retrospective clinical trials comparing ACL repair and ACLR. Data pertaining to tear location, surgical technique, adverse events, and clinical outcome measures were recorded. DerSimonian-Laird random-effects models were constructed to quantitatively evaluate the association between ACL repair/ACLR, adverse events, and clinical outcomes. A subanalysis of minimum 5-year outcomes was performed., Results: Twelve studies (893 patients; 464 ACLR and 429 ACL repair) were included. Random-effects models demonstrated a higher relative risk (RR) of recurrent instability/clinical failure (RR = 1.64; 95% confidence interval [CI], 1.04-2.57; P  = .032), revision ACLR (RR = 1.63; 95% CI, 1.03-2.59; P  = .039), and hardware removal (RR = 4.94; 95% CI, 2.10-11.61; P  = .0003) in patients who underwent primary ACL repair versus ACLR. The RR of reoperations and complications (knee-related) were not significantly different between groups. No significant differences were observed when comparing patient-reported outcome scores. In studies with minimum 5-year outcomes, no significant differences in adverse events or Lysholm scores were observed., Conclusion: In contemporary comparative trials of ACL repair versus ACLR, the RR of clinical failure, revision surgery due to ACL rerupture, and hardware removal was greater for primary ACL repair compared with ACLR. There were no observed differences in patient-reported outcome scores, reoperations, or knee-related complications between approaches. In the limited literature reporting on minimum 5-year outcomes, significant differences in adverse events or the International Knee Documentation Committee score were not observed., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: A.P. has received education payments from Smith+Nephew and hospitality payments from Medical Device Business Services.

Decarceration policies, enacted for SARS-CoV-2 mitigation in carceral settings, potentially exacerbated barriers to care for people living with HIV (PWH) with criminal legal involvement (CLI) during Shelter-in-Place (SIP) by limiting opportunities for engagement in provisions of HIV and behavioral health care. We compared health care engagement for PWH with CLI in San Francisco, California before and after decarceration and SIP using interrupted time series analyses. Administrative data identified PWH booked at the San Francisco County Jail with at least one clinic encounter from 01/01/2018-03/31/2020 within the municipal health care network. Monthly proportions of HIV, substance use, psychiatric and acute care encounters before (05/01/2019-02/29/2020) and after (03/01/2020-12/31/2020) SIP and decarceration were compared using Generalized Estimating Equation (GEE) log-binomial and logistic regression models, clustering on the patient-level. Of 436 patients, mean age was 43 years (standard-deviation 11); 88% cisgender-male; 39% white, 66% homeless; 67% had trimorbidity by Elixhauser score (medical comorbidity, psychotic disorder or depression, and substance use disorder). Clinical encounters immediately dropped following SIP for HIV (aOR = 0.77; 95% CI: 0.67, 0.90) and substance use visits (aRR = 0.83; 95% CI: 0.70, 0.99) and declined in subsequent months. Differential reductions in clinical encounters were seen among Black/African Americans (aRR = 0.93; 95% CI: 0.88, 0.99) and people experiencing homelessness (aRR = 0.92; 95% CI: 0.87, 0.98). Significant reductions in care were observed for PWH with CLI during the COVID-19 pandemic, particularly among Black/African Americans and people experiencing homelessness. Strategies to End the HIV Epidemic must improve engagement across diverse care settings to improve outcomes for this key population., (© 2023. The Author(s).)

Pharmacogenomics (PGx) can facilitate the transition to patient-specific drug regimens and thus improve their efficacy and reduce toxicity. The aim of this study was to evaluate the overlap of PGx classification for drug absorption, distribution, metabolism, and elimination (ADME)-related genes in the U.S. Food and Drug Administration (FDA) PGx labeling and in the Clinical Pharmacogenetics Implementation Consortium (CPIC) database. FDA-approved drugs and PGx labeling for ADME genes were identified in the CPIC database. Drugs were filtered by their association with ADME (pharmacokinetics)-related genes, PGx FDA labeling class, and CPIC evidence level. FDA PGx labeling was classified as either actionable, informative, testing recommended, or testing required, and varying CPIC evidence levels as either A, B, C, or D. From a total of 442 ADME and non-ADME gene-drug pairs in the CPIC database, 273, 55, and 48 pairs were excluded for lack of FDA labeling, mixed CPIC evidence level provisional classification, and non-ADME gene-drug pairs, respectively. The 66 ADME gene-drug pairs were classified into the following categories: 10 (15%) informative, 49 (74%) actionable, 6 (9%) testing recommended, and 1 (2%) testing required. CYP2D6 was the most prevalent gene among the FDA PGx labeling. From the ADME gene-drug pairs with both FDA and CPIC PGx classification, the majority of the drugs were for depression, cancer, and pain medications. The ADME gene-drug pairs with FDA PGx labeling considerably overlap with CPIC classification; however, a large number of ADME gene-drug pairs have only CPIC evidence levels but not FDA classification. PGx actionable labeling was the most common classification, with CYP2D6 as the most prevalent ADME gene in the FDA PGx labeling. Health professionals can impact therapeutic outcomes via pharmacogenetic interventions by analyzing and reconciling the FDA labels and CPIC database.

Introduction: Newer extraperitoneal techniques of laparoscopic ventral/incisional hernia repair (LVIHR) have been continually introduced since the popularity of the laparoscopic intraperitoneal onlay mesh technique began in 1993. One of which is the extended totally extraperitoneal (eTEP) approach allowing wide mesh augmentation, concurrent repair of diastasis recti, and performance of transversus abdominis release (TAR) for large/complex hernias. However, minimally invasive/laparoendoscopic ventral hernia repair is not yet widely adopted in the Philippines. We aim to share our preliminary experience with LVIHR using the eTEP approach., Methods: This was a retrospective review of all consecutive eTEP repairs for ventral hernia between January 2019 and September 2023. The clinical profiles of all patients were gathered. Hernia characteristics, operative profile, and postoperative outcomes were reported., Results: Thirty-five patients were included in the study with a mean age of 54.7; 60% were incisional hernias, and the most common hernia location was the umbilical area. A defect size between 4 and 10 cm was reported in 54.3%. eTEP-TAR was necessary in 12 patients. At a median follow-up of 16 months, two patients developed seroma, one hematoma, and two surgical site infections. All were successfully managed conservatively. Only one patient developed recurrence., Conclusion: eTEP approach is safe and feasible for repairing ventral hernias. Our preliminary experience showed acceptable outcomes similar to the published literature. Surgeons interested in this technique should be familiar with the abdominal wall anatomy, carefully select patients during preoperative planning, and undergo mentorship with hernia surgeons experienced with the technique to shorten the learning curve., (© 2024 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Rectal small cell carcinoma is a rare and aggressive cancer subtype for which a consensus of optimal treatment has not yet been reached. This cancer presents a difficult surgical problem, and thus, the mainstay of treatment tends to mirror that of small cell carcinoma of the lung (chemotherapy, radiation therapy, and immune modulators). This brief report highlights current treatment options available for this rare and difficult entity. There is a significant need for large-center clinical trials and prospective studies to help determine the best treatment regimen to effectively care for patients with small cell carcinoma of the rectum., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The application of enhanced recovery after surgery principles decreases postoperative complications (POCs), length of stay (LOS), and readmissions. Pharmacoprophylaxis decreases morbidity, but the effect of specific regimens on clinical outcomes is unclear., Methods and Materials: Records of 476 randomly selected adult patients who underwent elective colorectal surgeries (ECRS) at 10 US hospitals were abstracted. Primary outcomes were surgical site infection (SSI), venous thromboembolism (VTE), postoperative nausea and vomiting (PONV), pain, and ileus rates. Secondary outcomes included LOS and 7- and 30-day readmission rates., Results: POC rates were SSI (3.4%), VTE (1.5%), PONV (47.9%), pain (58.1%), and ileus (16.1%). Cefazolin 2 g/metronidazole 500 mg and ertapenem 1 g were associated with the shortest LOS; cefotetan 2 g and cefoxitin 2 g with the longest LOS. No SSI occurred with ertapenem and cefotetan. More Caucasians than Blacks received oral antibiotics before intravenous antibiotics without impact. Enoxaparin 40 mg subcutaneously daily was the most common inpatient and discharge VTE prophylaxis. All in-hospital VTEs occurred with unfractionated heparin. Most received rescue rather than around-the-clock antiemetics. Scopolamine patches, spinal opioids, and IV lidocaine continuous infusion were associated with lower PONV. Transversus abdominis plane block with long-acting local anesthetics, celecoxib, non-anesthetic ketamine bolus, ketorolac IV, lidocaine IV, and pregabalin were associated with lower in-hospital pain severity rates. Gabapentinoids and alvimopan were associated with lower ileus rates. Acetaminophen, alvimopan, famotidine, and lidocaine patches were associated with shorter LOS., Conclusions: Significant differences in pharmacotherapy regimens that may improve primary and secondary outcomes in ECRS were identified. In adult ECRS, cefotetan or ertapenem may be better regimens for preventing in-hospital SSI, while ertapenem or C/M may lead to shorter LOS. The value of OA to prevent SSI was not demonstrated. Inpatient enoxaparin, compared to UFH, may reduce VTE rates with a similar LOS. A minority of patients had a documented PONV risk assessment, and a majority used as-needed rather than around-the-clock strategies. Preoperative scopolamine patches continued postoperatively may lower PONV and PDNV severity and shorter LOS. Alvimopan may reduce ileus and shorten LOS. Anesthesia that includes TAP block, ketorolac IV, and pregabalin use may lead to reduced pain rates. Acetaminophen, alvimopan, famotidine, and lidocaine patches may shorten LOS. Given the challenges of pain management and the incidence of PONV/PDNV found in this study, additional studies should be conducted to determine optimal opioid-free anesthesia and the benefit of newer antiemetics on patient outcomes. Moreover, future research should identify latent pharmacotherapy variables that impact patient outcomes, correlate pertinent laboratory results, and examine the impact of order or care sets used for ECRS at study hospitals.

Background: Urinary Tract Infections (UTIs) during gravidity are among the most preponderant contagion globally and can culminate in fetal and maternal mortality. Lack of awareness and poor preventive practices can exacerbate this outcome. This study assessed the knowledge and preventive practices of antenatal mothers' towards UTIs in pregnancy., Design: This was a cross-sectional descriptive survey involving antenatal mothers in selected health care facilities in Ekiti State., Methods: A pre-tested adapted questionnaire was used for data collection. Data was analyzed using descriptive statistics and Chi-square at p  < 0.05., Results: The mean respondents' age was 24.6 ± 2.1 years and barely less than half (43.8%) were multigravida. The findings of the study revealed that 64.0% of the respondents had good knowledge of UTIs. Overall, majority (78.9%) of the respondents exhibit good preventive practices toward UTIs in pregnancy, although the prevalence of UTIs among the studied subjects was found to be high (54.1%), with nearly half (48.7%) of the respondents reported been tested once for UTIs in the current pregnancy. Furthermore, there was a statistically significant relationship between educational level and respondents' knowledge on the prevention of UTIs in pregnancy ( p  = 0.00; p  < 0.05)., Conclusions: Respondents had good knowledge and good preventive practices toward UTIs. However, the high prevalence of UTIs reported among respondents justifies the need for implementation of knowledge enhancement program, routine testing and prompt treatment of UTIs among antenatal mothers., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

The aim of the current study was to conduct a reliability generalisation (RG) meta-analysis of Cronbach's alpha for the Insomnia Severity Index (ISI). A systematic search of three databases (PubMed, Scopus, and Web of Science) from inception to 12 March 2021 was performed. Publications that reported Cronbach's alpha for the total ISI score were included. Only psychometric-focussed studies were considered. Meta-analysis was carried out using a random-effects model to derive a pooled estimate of Cronbach's alphas. The number of participants in the included publications ranged from 25 to 12,056, with 33 studies (42 estimates) comprising internal consistency coefficients, and a combined sample size of N = 29,688. The age range of the included publications was from 13.4 to 74.3 years. Data extraction implied 33 publications out of 706 found through the database search. Cronbach's alphas ranged from 0.65 to 0.92. The majority of the reported coefficients were ≥0.7 and presented a low risk of bias (n = 32). The pooled alpha coefficient was 0.83 (IC [0.81-0.85]; SE = 0.009) with high heterogeneity among the included publications (I 2  = 97%). Subgroup analyses including moderators such as continent, setting, risk of bias, and age did not affect significantly the overall result. In general, the cumulative estimate of Cronbach's alpha for the ISI is good. However, this finding should be interpreted with caution since there is a high heterogeneity level and some of the studies might not have checked the assumptions underlying Cronbach's alphas., (© 2023 The Authors.

Traditional birth attendants (TBAs) have become an integral part of the workforce providing delivery services in Nigeria due to the limited number of skilled birth attendants and cultural preferences. This study assessed the knowledge, management and preventive practices regarding postpartum haemorrhage (PPH) among TBAs in selected communities in Osun State, Southwest Nigeria. The study employed a descriptive cross-sectional study design and recruited 260 TBAs in four communities in Osun State. Data were collected by means of an adapted semi-structured questionnaire. Data were analysed using SPSS version 23 and summarized using descriptive and inferential statistics (chi-square and logistic regression) with the level of significance set at p < 0.05. The findings indicated that most (71.4%) of the TBAs were cleric, while others were herbalist (28.6%). Although the majority (76.4%) of the TBAs had good knowledge of the causes and warning signs of PPH, a high percentage (69.3%) of TBAs had poor management practices, while 114 (64.1%) TBAs had inadequate preventive practices. Notably, almost none of the participants practised active management of the third stage of labour; the majority of TBAs did not administer any uterotonic drugs to the mother, nor did they deliver the placenta by controlled cord traction. Gender (P = 0.029), educational level (P = 0.035) and average number of births per month (P = 0.001) significantly influenced TBAs' management practices. Similarly, the TBA type (P < 0.001), average number of births per month (P = 0.003) and experience with formal training (P = 0.005) showed significant associations with TBAs' preventive practices. Furthermore, TBAs' preventive practices towards PPH were influenced by the TBA type (OR: 4.23; 95% CI 1.64-10.90). TBA management practices were also influenced by the TBA type (OR: 4.42; 95% CI 2.03-9.61). Traditional birth attendants in this study had poor management and poor preventive practices for postpartum haemorrhage., (© 2023. The Author(s).)

Very little is known about pediatric media guidance, or the one-on-onse advice that medical and clinical professionals (MCPs) communicate to parents about their children's recreational media and technology (RMT) use. One population that stands to benefit from a closer examination is children on the autism spectrum due to their behavior and communication challenges. We surveyed one group of pediatric autism MCPs, applied behavioral analysis (ABA) providers ( N = 234), due to their proximity to families and conducted an applied thematic analysis of RMT advice they deliver. Providers reported primarily suggesting that caregivers employ restrictive parental mediation with their autistic child, that RMT should primarily be limited to use as a reward or reinforcement, and that parents should set time limits. Our findings offer new insights into the intersections of health communication theory and practice, while highlighting the need for greater research into RMT guidance for children with and without disabilities.

Toxicity arising from environmental contaminants has attracted global interest in the last few decades, due to the high morbidity and mortality associated with them. Efforts have been made to combat the consequential outcomes of environmental toxicity in humans through traditional remediation techniques and therapeutic measures which have been hampered by one or more limitations. Consequently, this scenario has triggered interest in the medicinal properties of phytochemicals. Thus, this review gives a succinct and in-depth elucidation of the various environmental contaminants and their toxicity effects on humans. It delves into the various classes of phytochemicals and their intervention roles. The study adopted a desk review of existing literatures from scientific reports and peer reviewed articles through triangulation of data sources. "Phytochemicals" are group of secondary metabolites obtained from plants with medicinal properties. These groups of compounds are included but not limited to flavonoids, tannins, saponins, alkaloids, cardenoloids, terpenoids, and phytosteroids. This review corroborates the prophylactic and therapeutics efficacy of these phytochemicals as anti-metastatic, anti-inflammatory, anti-aging, anti-oxidant, anti-microbial and live saving substances with empirical findings from several laboratory, clinical trials and epidemiologic studies. It conclude that given the wide range of medicinal properties of phytochemicals, there is an urgent need for its full optimization in the pharmaceutical industry and future studies should focus on identifying the bioactive molecules in these compounds and its effectiveness against mixer toxicity., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Over the past few decades, research has suggested that cognitive variables play a key role in sleep disorders, particularly, in insomnia. The SLOC (Sleep Locus of Control Scale) evaluates the sleep locus of control, which is associated with the degree to which an individual attributes her/his experiences of sleep to chance or internal causes. The aim of this study was to develop the first translation and adaptation of the SLOC into the European Portuguese, as well as to analyze its psychometric properties. In this study, it was recruited a sample of 2029 Portuguese Higher Education students, aged ≥ 18 years, where approximately 75% of the sample were women and 25% men. The results showed that the SLOC had acceptable internal consistency value ( α  = .64), considering that it is a measure with a reduced number of items. As in the original study, a principal component analysis with varimax rotation identified two components. A parallel analysis was also conducted, identifying two factors. The correlation between the two subscales "internal sleep locus of control" and "chance sleep locus of control" was positive albeit of low magnitude ( r  = .15). Through the analysis carried out, it was also observed that individuals with "insomnia", relative to those without, had a more chance sleep locus of control. Overall, these findings show similarities with the original study. The SLOC seems to be a useful psychological assessment measure to be used in clinical and research settings., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

Objectives: Clinical Pharmacogenetics Implementation Consortium (CPIC) is a platform that advances the pharmacogenomics (PGx) practice by developing evidence-based guidelines. The purpose of this study was to analyze the CPIC database for ADME related genes and their corresponding drugs, and evidence level for drug-gene pairs; and to determine the presence of these drug-gene pairs in the highest mortality diseases in the United States., Methods: CPIC database was evaluated for drug-gene pairs related to absorption, distribution, metabolism, and excretion (ADME) properties. National Vital Statistics from Centers for Disease Control and Prevention was used to identify the diseases with the highest mortality. CPIC levels are assigned to different drug-gene pairs based on varying levels of evidence as either A, B, C, or D. All drug-gene pairs assigned with A/B, B/C, or C/D mixed levels were excluded from this study. A stepwise exclusion process was followed to determine the prevalence of various ADME drug-gene pairs among phase I/II enzymes or transporters and stratify the drug-gene pairs relevant to different disease conditions most commonly responsible for death in the United States., Results: From a total of 442 drug-gene pairs in the CPIC database, after exclusion of 86 drug-gene pairs with levels A/B, B/C, or C/D, and 211 non-ADME related genes, 145 ADME related drug-gene pairs resulted. From the 145 ADME related drug-genes pairs, the following were the distribution of levels: Level A: 43 (30%), Level B: 22 (15%), Level C: 59 (41%), Level D: 21 (14%). The most prevalent ADME gene with CPIC level A classification was cytochrome P450 2C9 ( CYP2C9 ) (26%) and overall, the most prevalent ADME gene in the CPIC database was CYP2D6 (30%). The most prevalent diseases related to the CPIC evidence related drugs were cancer and depression., Conclusions: We found that there is an abundance of ADME related genes in the CPIC database, including in the high mortality disease states of cancer and depression. There is a differential level of pharmacogenomic evidence in drug-gene pairs enlisted in CPIC where levels A and D having the greatest number of drug-gene pairs. CYP2D6 was the most common ADME gene with CPIC evidence for drug-gene pairs. Pharmacogenomic applications of CPIC evidence can be leveraged to individualize patient therapy and lower adverse effect events., (© 2022 Walter de Gruyter GmbH, Berlin/Boston.)

The study assessed the maternal satisfaction with delivery care in selected health care facilities in Ekiti state. The study employed a descriptive cross-sectional study design and a simple random sampling technique was utilized to select respondents based on calculated sample size and a total of 267 respondents participated in the study. A semi-structured pretested questionnaire was used for the data collection. Data was analyzed and summarized using descriptive statistics and inferential statistics (Chi-square) with significance set at p  < 0.05. The mean respondents' age was 28.2 ± 1.4 years with majority falling within the age group of 21-30 years. Majority of the respondents revealed to be satisfied with the following: proximity of the health facilities 194 (72.7%); cost of service 174 (65.2%); drug availability 184 (69.7%); cleanliness of the hospital ambience 219 (82.0%); and professional conduct of the care givers 186 (70.2%). However, the respondents expressed dissatisfaction in terms of the following: referral link 107 (40.1%); waiting time 122 (45.7%); communication gap 56 (21.0%); and maintenance of privacy 51 (19.1%). Overall, majority (94.8%) of the respondents were satisfied with the delivery services rendered at the facilities while 14 (5.2%) expressed dissatisfaction. Furthermore, a significant association exists between respondents' level of education and maternal satisfaction on delivery care ( p  < 0.05). Although the general maternal gratification/satisfaction on intrapartum and postpartum care in this study was overwhelmingly high, the few domains of discontentment identified need to be addressed by all the stakeholders in the health sector to enhance the usage of health care services amongst women, thus promoting the attainment of Sustainable Development Goal (SDG) 3., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Purpose: The purpose of this study was to 1) determine the demographic differences between adults who have accepted, or plan to accept, the COVID-19 vaccine and those who will not accept the COVID-19 vaccine and 2) describe the potential influencers in deciding to accept the COVID-19 vaccine among adults living in the United States who have accepted or plan to accept the vaccine., Design: A cross-sectional design utilizing an online survey was deployed using social media and a crowdsourcing platform., Setting: United States., Subjects: One thousand three hundred ninety-five (1395) adults completed the survey. The majority were white, male, between the ages of 25 and 45, and with representation from 50 states and Puerto Rico., Measures: A two-branched survey was used to assess demographic information, vaccination intention, and 19 potential influencers of COVID-19 vaccine acceptance., Analysis: Analysis included descriptive statistics and Chi-square tests to determine differences between groups., Results: A higher proportion of male ( P < .001), married ( P < .001), and college-educated ( P < .001) participants reported acceptance of the vaccine. The factors with the highest mean score of reported level of influence were duty to protect the vulnerable and contribution to move society back to a sense of normalcy., Conclusion: Understanding the potential influencers of vaccine acceptance may provide insight into strategies that could increase vaccination uptake.

Light and lighting protocols of animal research facilities are critically important to the outcomes of biomedical research that uses animals. Previous studies from our laboratory showed that the wavelength (color) of light in animal housing areas affects the nocturnal melatonin signal that temporally coordinates circadian rhythms in rodents. Here, we tested the hypothesis that exposure to LED light enriched in the blue-appearing portion (460-480 nm) of the visible spectrum during the light phase (bLAD) influences circadian concentrations of select neuroendocrine hormones in adolescent Sprague-Dawley rats. Male and female rats (4 to 5 wk old) were housed on a novel IVC system under a 12L:12D in either cool-white fluorescent (control, n = 72) or bLAD (experimental, n = 72) lighting. Every third day, body weight and food and water consumption were measured. On Day 30, rats were anesthetized with ketamine/xylazine and terminal collection of arterial blood was performed to quantify serum concentrations of melatonin, corticosterone, insulin, and glucose at 6 circadian time points (0400, 0800, 1200, 1600, 2000, 2400). As compared with male and female rats housed under cool white fluorescent (CWF) lighting, rats in bLAD lighting showed a 6-fold higher peak in dark phase serum melatonin ( P < 0.05). Effects on serum corticosterone were sex dependent, as CWF and bLAD females had significantly higher corticosterone levels than did CWF and bLAD males, respectively. CWF and bLAD females had significantly higher serum glucose overall as compared with males. However, serum insulin was not affected by sex (M or F) or lighting conditions (CWF or bLAD). These data show that housing Sprague-Dawley rats under bLAD lighting conditions increases circadian peaks of melatonin without increasing serum levels of corticosterone, glucose or insulin, indicating less variation of circadian cycling of key neuroendocrine hormones in bLAD-exposed rats.

Background: The Nigerian government initiated various national infant and young child feeding programmes (1992-2005) to improve juveniles well-being. Despite these efforts, under-five children feeding related diseases and mortality still escalate. Investigating the drivers of exclusive breastfeeding (EBF) is exigent in tackling this menace., Objective: To investigate maternal socio-demographic and index child variables that serve as predictors of EBF practice among nursing mother attending a healthcare facility in Lagos, western Nigeria., Methods: One hundred and twenty (N=120) consenting nursing mothers (15-49 years) with infants between 0-24 months completed a structured, self-administered questionnaire. Scores of current practice level for EBF was computed and adjusted odd ratios (aORs) generated from a logistic regression model., Results: Respondents mean age was 28.7 ± 2.3 years. Of 120 respondents, 82(68.3%) and 38(31.7%) had good and poor EBF practice respectively. Having an index child <6months age (aOR=5.02, 95% confidence intervalCI=1.28-15.43), being in monogamy (aOR=3.0, 95% CI=1.80-6.73), having tertiary education (aOR=3.12, 95% CI=1.39-8.96), being married (aOR=2.0, 95% CI=0.1-0.8) and vaginal delivery (aOR=2.96, 95% CI=1.75-7.48) increased the odds of EBF practice., Conclusion: Age of index child, marriage type, maternal education, marital status and nature of delivery independently predicted EBF practice., (© 2022 Sokan-Adeaga MA et al.)

Predation is a fundamental ecological process that shapes communities and drives evolutionary dynamics. As the world rapidly urbanizes, it is critical to understand how human perturbations alter predation and meat consumption across taxa. We conducted a meta-analysis to quantify the effects of urban environments on three components of trophic ecology in predators: dietary species richness, dietary evenness and stable isotopic ratios (IRs) ( δ 13 C and δ 15 N IR). We evaluated whether the intensity of anthropogenic pressure, using the human footprint index (HFI), explained variation in effect sizes of dietary attributes using a meta-regression. We calculated Hedges' g effect sizes from 44 studies including 11 986 samples across 40 predatory species in 39 cities globally. The direction and magnitude of effect sizes varied among predator taxa with reptilian diets exhibiting the most sensitivity to urbanization. Effect sizes revealed that predators in cities had comparable diet richness, evenness and nitrogen ratios, though carbon IRs were more enriched in cities. We found that neither the 1993 nor 2009 HFI editions explained effect size variation. Our study provides, to our knowledge, the first assessment of how urbanization has perturbed predator-prey interactions for multiple taxa at a global scale. We conclude that the functional role of predators is conserved in cities and urbanization does not inherently relax predation, despite diets broadening to include anthropogenic food sources such as sugar, wheat and corn.

Background: The interscalene nerve block provides analgesia for shoulder surgery. To extend block duration, provide adequate analgesia, and minimize opioid consumption, the use of adjuvants such as dexamethasone as well as the application of perineural liposomal bupivacaine have been proposed. This randomized, double-blinded, noninferiority trial hypothesized that perineural liposomal bupivacaine is noninferior to standard bupivacaine with perineural dexamethasone in respect to average pain scores in the first 72 h after surgery., Methods: A total of 112 patients undergoing ambulatory shoulder surgery were randomized into two groups. The liposomal bupivacaine group received a 15-ml premixed admixture of 10 ml of 133 mg liposomal bupivacaine and 5 ml of 0.5% bupivacaine (n = 55), while the bupivacaine with dexamethasone group received an admixture of 15 ml of 0.5% standard bupivacaine with 4 mg dexamethasone (n = 56), respectively. The primary outcome was the average numerical rating scale pain scores at rest over 72 h. The mean difference between the two groups was compared against a noninferiority margin of 1.3. Secondary outcomes were analgesic block duration, motor and sensory resolution, opioid consumption, numerical rating scale pain scores at rest and movement on postoperative days 1 to 4 and again on postoperative day 7, patient satisfaction, readiness for postanesthesia care unit discharge, and adverse events., Results: A liposomal bupivacaine group average numerical rating scale pain score over 72 h was not inferior to the bupivacaine with dexamethasone group (mean [SD], 2.4 [1.9] vs. 3.4 [1.9]; mean difference [95% CI], -1.1 [-1.8, -0.4]; P < 0.001 for noninferiority). There was no significant difference in duration of analgesia between the groups (26 [20, 42] h vs. 27 [20, 39] h; P = 0.851). Motor and sensory resolutions were similar in both groups: 27 (21, 48) h versus 27 (19, 40) h (P = 0.436) and 27 [21, 44] h versus 31 (20, 42) h (P = 0.862), respectively. There was no difference in opioid consumption, readiness for postanesthesia care unit discharge, or adverse events., Conclusions: Interscalene nerve blocks with perineural liposomal bupivacaine provided effective analgesia similar to the perineural standard bupivacaine with dexamethasone. The results show that bupivacaine with dexamethasone can be used interchangeably with liposomal bupivacaine for analgesia after shoulder surgery., (Copyright © 2022, the American Society of Anesthesiologists.

Background: Analyzing outcomes and the minimal clinically important difference (MCID) after anterior cruciate ligament reconstruction (ACLR) is of increased interest in the orthopaedic literature. The purposes of this study were to report outcomes after ACLR at medium to long-term follow-up, identify the threshold preoperative outcome values that would be predictive of achieving the MCID postoperatively, and analyze outcome maintenance at medium to long-term follow-up after ACLR., Methods: Active athletes who underwent ACLR were identified in an institutional ACL registry. Patient-reported outcome measures (PROMs) were administered preoperatively and at the 2-year and >5-year postoperative follow-up; measures included the International Knee Documentation Committee (IKDC) form, the 12-item Short Form Health Survey (SF-12) Physical Component Summary (PCS) and Mental Component Summary (MCS), and Lysholm scale. We calculated the MCID from baseline to each of the 2 follow-up periods (2-year and mean 7.7-year). Logistic regression was performed to investigate factors associated with achievement of the MCID., Results: A total of 142 patients (mean follow-up, 7.7 years [range, 6.6 to 9.1 years]) underwent ACLR. The mean age and body mass index at the time of surgery were 27.2 ± 13.0 years and 23.2 ± 3.0 kg/m 2 , respectively. Final postoperative outcome scores improved significantly from baseline for the IKDC (50.9 ± 14.7 to 87.9 ± 11.2), SF-12 PCS (41.6 ± 8.9 to 55.6 ± 3.2), and Lysholm scale (62.2 ± 17.6 to 90.5 ± 10.3) (p < 0.0001), while the SF-12 MCS did not improve significantly (54.2 ± 8.0 to 54.4 ± 6.0) (p = 0.763). Between 2- and >5-year follow-up, the SF-12 PCS showed significant improvement (54.6 ± 4.5 to 55.6 ± 3.2; p = 0.036), while no change was noted in the IKDC (87.6 ± 11.1 to 87.9 ± 11.2), SF-12 MCS (55.5 ± 5.3 to 54.4 ± 6.0), and Lysholm scale (89.8 ± 10.6 to 90.5 ± 10.3) (p ≥ 0.09). At the time of final follow-up, the MCID was achieved by 94.7% of patients for the IKDC, 80.8% for the Lysholm, 79.0% for the SF-12 PCS, and 28.2% for the SF-12 MCS. At 2-year follow-up, 95.3% of patients were either "very" or "somewhat" satisfied with their surgery, compared with 88.6% at the time of final follow-up., Conclusions: We found a high level of maintained function following ACLR. The IKDC, SF-12 PCS, and Lysholm scores improved significantly after ACLR at the time of final follow-up and were not significantly different between follow-up periods. Approximately 95% and 89% of patients reported being satisfied with the outcome of surgery at the 2-year and final follow-up, respectively., Level of Evidence: Therapeutic Level IV.

Background: Understanding specific risk profiles for each patient and their propensity to experience clinically meaningful improvement after anterior cruciate ligament reconstruction (ACLR) is important for preoperative patient counseling and management of expectations., Purpose: To develop machine learning algorithms to predict achievement of the minimal clinically important difference (MCID) on the International Knee Documentation Committee (IKDC) score at a minimum 2-year follow-up after ACLR., Study Design: Case-control study; Level of evidence, 3., Methods: An ACLR registry of patients from 27 fellowship-trained sports medicine surgeons at a large academic institution was retrospectively analyzed. Thirty-six variables were tested for predictive value. The study population was randomly partitioned into training and independent testing sets using a 70:30 split. Six machine learning algorithms (stochastic gradient boosting, random forest, neural network, support vector machine, adaptive gradient boosting, and elastic-net penalized logistic regression [ENPLR]) were trained using 10-fold cross-validation 3 times and internally validated on the independent set of patients. Algorithm performance was assessed using discrimination, calibration, Brier score, and decision-curve analysis., Results: A total of 442 patients, of whom 39 (8.8%) did not achieve the MCID, were included. The 5 most predictive features of achieving the MCID were body mass index ≤27.4, grade 0 medial collateral ligament examination (compared with other grades), intratunnel femoral tunnel fixation (compared with suspensory), no history of previous contralateral knee surgery, and achieving full knee extension preoperatively. The ENPLR algorithm had the best relative performance (C-statistic, 0.82; calibration intercept, 0.10; calibration slope, 1.15; Brier score, 0.068), demonstrating excellent predictive ability in the study's data set., Conclusion: Machine learning, specifically the ENPLR algorithm, demonstrated good performance for predicting a patient's propensity to achieve the MCID for the IKDC score after ACLR based on preoperative and intraoperative factors. The femoral tunnel fixation method was the only significant intraoperative variable. Range of motion and medial collateral ligament integrity were found to be important physical examination parameters. Increased body mass index and prior contralateral surgery were also significantly predictive of outcome., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: A.S.R. has received research support from DePuy and Stryker; consulting fees from Ceramtec, Medtronic, Moximed, Smith & Nephew, and Stryker; speaking fees from Ceramtec, Medtronic, Smith & Nephew, and Stryker Mako; and royalties from DePuy, Saunders/Mosby–Elsevier, Springer, and Stryker Mako and has stock/stock options in ConforMIS and Enhatch.

Redondoviridae is a newly established family of circular Rep-encoding single-stranded (CRESS) DNA viruses found in the human ororespiratory tract. Redondoviruses were previously found in ∼15% of respiratory specimens from U.S. urban subjects; levels were elevated in individuals with periodontitis or critical illness. Here, we report higher redondovirus prevalence in saliva samples: four rural African populations showed 61 to 82% prevalence, and an urban U.S. population showed 32% prevalence. Longitudinal, limiting-dilution single-genome sequencing revealed diverse strains of both redondovirus species ( Brisavirus and Vientovirus ) in single individuals, persistence over time, and evidence of intergenomic recombination. Computational analysis of viral genomes identified a recombination hot spot associated with a conserved potential DNA stem-loop structure. To assess the possible role of this site in recombination, we carried out in vitro studies which showed that this potential stem-loop was cleaved by the virus-encoded Rep protein. In addition, in reconstructed reactions, a Rep-DNA covalent intermediate was shown to mediate DNA strand transfer at this site. Thus, redondoviruses are highly prevalent in humans, found in individuals on multiple continents, heterogeneous even within individuals and encode a Rep protein implicated in facilitating recombination. IMPORTANCE Redondoviridae is a recently established family of DNA viruses predominantly found in the human respiratory tract and associated with multiple clinical conditions. In this study, we found high redondovirus prevalence in saliva from urban North American individuals and nonindustrialized African populations in Botswana, Cameroon, Ethiopia, and Tanzania. Individuals on both continents harbored both known redondovirus species. Global prevalence of both species suggests that redondoviruses have long been associated with humans but have remained undetected until recently due to their divergent genomes. By sequencing single redondovirus genomes in longitudinally sampled humans, we found that redondoviruses persisted over time within subjects and likely evolve by recombination. The Rep protein encoded by redondoviruses catalyzes multiple reactions in vitro , consistent with a role in mediating DNA replication and recombination. In summary, we identify high redondovirus prevalence in humans across multiple continents, longitudinal heterogeneity and persistence, and potential mechanisms of redondovirus evolution by recombination.

For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more accurately with the video clip than with spoken cues only, and significantly more accurately with spoken cues only relative to the sequence of graphic symbols. Results suggest that the short video clip along with spoken cues may be an optimal mode for enhancing learners' ability to follow directives containing prepositions. In addition, results reveal three statistically significant correlations between participants' preexisting skills and directive-following accuracy: a positive correlation between spoken preposition preassessment total score and accuracy in the spoken-alone condition; a positive correlation between spoken noun preassessment total score and accuracy in the video-clip condition; and a positive correlation between ASD severity and the need for repetition in the video-clip condition. Results also suggested that, for children with more severe ASD symptoms, the video clips require repetitions so that the relationships illustrated within it can gain more semantic salience. Implications for clinical practice and future research are discussed.

On 11 March 2020, the World Health Organization (WHO) classified the Coronavirus Disease 2019 (COVID-19) as a global pandemic, which tested healthcare systems, administrations, and treatment ingenuity across the world. COVID-19 is caused by the novel beta coronavirus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Since the inception of the pandemic, treatment options have been either limited or ineffective. Remdesivir, a drug originally designed to be used for Ebola virus, has antiviral activity against SARS-CoV-2 and has been included in the COVID-19 treatment regimens. Remdesivir is an adenosine nucleotide analog prodrug that is metabolically activated to a nucleoside triphosphate metabolite (GS-443902). The active nucleoside triphosphate metabolite is incorporated into the SARS-CoV-2 RNA viral chains, preventing its replication. The lack of reported drug development and characterization studies with remdesivir in public domain has created a void where information on the absorption, distribution, metabolism, elimination (ADME) properties, pharmacokinetics (PK), or drug-drug interaction (DDI) is limited. By understanding these properties, clinicians can prevent subtherapeutic and supratherapeutic levels of remdesivir and thus avoid further complications in COVID-19 patients. Remdesivir is metabolized by both cytochrome P450 (CYP) and non-CYP enzymes such as carboxylesterases. In this narrative review, we have evaluated the currently available ADME, PK, and DDI information about remdesivir and have discussed the potential of DDIs between remdesivir and different COVID-19 drug regimens and agents used for comorbidities. Considering the nascent status of remdesivir in the therapeutic domain, extensive future work is needed to formulate safer COVID-19 treatment guidelines involving this medication.

Purpose: To determine which interventions optimize clinical outcomes in adhesive capsulitis by performing a network meta-analysis of randomized controlled trials., Methods: A systematic review was conducted of all clinical trials on adhesive capsulitis published since 2008. Patient cohorts were grouped into treatment categories; data collected included range of motion (ROM) and patient-reported outcome measures (PROMs). Interventions were compared across groups by means of arm-based Bayesian network meta-analysis in a random-effects model., Results: Sixty-six studies comprising 4042 shoulders (57.6% female patients, age 54.8 ± 3.2 years [mean ± standard deviation]) were included. The most commonly studied interventions were physical therapy (PT) or shoulder injections. Network meta-analysis demonstrated that arthroscopic surgical capsular release was the most effective treatment in increasing ROM. This effect was apparent in forward flexion (effect difference [ED] versus placebo, 44°, 95% confidence interval [CI] 31° to 58°), abduction (ED 58°, 45° to 71°), internal rotation (ED 34°, 24° to 44°), and external rotation (ED 59°, 37° to 80°). Interventions most effective for pain relief included PT supplemented with either medical therapy (ED -4.50, -9.80 to 2.80) or ultrasound therapy (ED -5.10, -5.10 to -1.40). Interventions most effective for improvement of functional status included PT, manipulation under anesthesia (MUA), intra-articular or subacromial steroid injection, surgical capsular release, and supplementation of PT with alternative therapy., Conclusions: No one treatment emerged superior in regard to ROM, pain symptoms, and functional status. Surgery (after failure of conservative treatment) ranked highest across all ROM domains. Treatments that ranked highest for treatment of pain included PT supplemented with either medical therapy or ultrasound. Finally, treatments that ranked highest for improvements in functional status included MUA, PT with medical therapy, surgical intervention, PT with ultrasound, PT with injection, and injection alone., Level of Evidence: II, systematic review and network meta-analysis of level I and II studies., (Copyright © 2020 Arthroscopy Association of North America.

Purpose: To evaluate the quality of orthopaedic cost-effectiveness analyses (CEAs) in accordance with the 2016 recommendations by the Second Panel on Cost-Effectiveness in Health and Medicine., Methods: A systematic review of all CEAs from September 2017 to September 2019 in the 10 highest impact orthopaedic surgery journals was performed. Quality scoring used the Quality of Health Economic Studies (QHES) instrument and the Second Panel checklist. QHES scores ≥80 were considered high quality and <50 poor quality. Mann-Whitney U and independent samples Kruskal-Wallis tests compared individual and multiple groups, respectively. Linear regression analysis was performed to correlate QHES score, checklist item fulfillment, and impact factor., Results: The 10 highest impact orthopaedic journals published 6,323 articles with 35 (0.55%) meeting inclusion criteria. Total joint arthroplasty (TJA) and sports medicine articles comprised 65.7% of included studies. Overall mean QHES score was 89.0 ± 7.6, with 82.8% considered high quality. Mean proportion of Second Panel checklist items fulfilled was 82.1% ± 13.3%, but no studies performed an impact inventory accounting for consequences within and outside the health care sector or discussed ethical implications. Mean QHES score and satisfied checklist items were significantly different by journal (P = .025 and P = .01, respectively). In addition, there was a moderate positive correlation between QHES score and impact factor (r = 0.446, P = .007). TJA CEAs satisfied a higher number of checklist items compared with spine surgery CEAs., Conclusions: Recent orthopaedic CEAs have generally been high quality according to updated Second Panel guidelines but consistently miss checklist items relating to societal impact and ethics. TJA and sports medicine continue to be the most frequently studied orthopaedic subspecialties in health economics, and the breadth of orthopaedic procedures analyzed by CEAs has improved., Study Design: Level IV, systematic review., (Copyright © 2021.

Job loss and evictions tied to the Coronavirus Disease 2019 (COVID-19) pandemic are expected to increase homelessness significantly in the coming months. Reciprocally, homelessness and the many vulnerabilities that inevitably accompany it are driving COVID-19 outbreaks in US shelters and other congregate living situations. Unless we intervene to address homelessness, these co-existing and synergistic situations will make the current public health crisis even worse. Preventing homelessness and providing permanent affordable housing has reduced the ravages of the HIV epidemic. We must take the lessons learned in 40 years of fighting HIV to respond effectively to the COVID-19 crisis. Housing is an investment that will curb the spread of COVID-19 and help protect all of us from future pandemics., (© The Author(s) 2020.
