Comparison of rerupture rates after operative and nonoperative management of Achilles tendon rupture in older populations: Systematic review and meta-analysis.

Background: This systematic review and meta-analysis investigated the treatment for Achilles tendon rupture (ATR) associated with the lowest risk of rerupture in older patients. Methods: Five databases were searched through September 2022 for studies published in the past 10 years analyzing operative and nonoperative ATR treatment. Studies were categorized as "nonelderly" if they reported only on patients aged 18-60 years. Studies that included at least 1 patient older than age 70 were categorized as "elderly inclusive." Of 212 studies identified, 28 were eligible for inclusion. Of 2965 patients, 1165 were treated operatively: 429 (37%) from elderly-inclusive studies and 736 (63%) from nonelderly studies. Of the 1800 nonoperative patients 553 (31%) were from nonelderly studies and 1247 (69%) were from elderly-inclusive studies. Results: For nonoperative treatment, the rate of rerupture was higher in nonelderly studies (83/1000 cases, 95% CI = 58, 113) than in elderly-inclusive studies (38/1000 cases, 95% CI = 22, 58; P<.001). For operative treatment no difference was found in the rate of rerupture between nonelderly studies (7/1000 cases, 95% CI = 0, 21) and elderly-inclusive studies (12/1000 cases, 95% CI = 0, 35; P<.78). Overall, operative treatment was associated with a rerupture rate of 1.5% (95% CI: 1.0%, 2.8%) (P<.001), which was lower than the 5% rate reported by other studies for nonoperative management (P<.001). Conclusion: Older patients may benefit more than younger patients from nonoperative treatment of ATR. More studies are needed to determine the age at which rerupture rates decrease among nonoperatively treated patients. Level of Evidence: 3.

Zinc Supplementation Associated With a Decrease in Mortality in COVID-19 Patients: A Meta-Analysis.

The COVID-19 pandemic has had a significant impact on the world, resulting in millions of deaths worldwide and imposing economic, political, and social problems. The use of nutritional supplementation for the prevention and mitigation of COVID-19 remains controversial. This meta-analysis aims to investigate the association between zinc supplementation, mortality, and symptomatology, among COVID-19-infected patients. A meta-analysis was conducted to compare the outcomes of mortality and symptomology of patients with COVID-19 receiving zinc supplementation and those not receiving zinc supplementation. PubMed/Medline, Cochrane, Web of Science, and CINAHL Complete were independently searched with the search terms "zinc" AND "covid" OR "sars-cov-2" "COVID-19" OR "coronavirus". After duplicates were removed, 1215 articles were identified. Five of these studies were used to assess mortality outcomes, and two were used to assess symptomatology outcomes. The meta-analysis was conducted through R 4.2.1 software (R Foundation, Vienna, Austria). Heterogeneity was evaluated by calculating the I2 index. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. It was found that COVID-19-infected individuals treated with zinc supplements had a reduced risk of mortality compared with individuals not treated with a zinc supplement RR=0.63 (95%CI;0.52,0.77), p=0.005. For symptomology, it was found that COVID-19-infected individuals treated with zinc had no difference in symptomology than individuals not treated with a zinc supplement RR=0.52 (95%CI;0.00,24315.42), p=0.578. This data indicates that zinc supplementation is associated with decreased mortality in those with COVID-19 but does not change symptomatology. This is promising as zinc is widely available and may be valuable as a cost-effective way to prevent poor outcomes for those with COVID-19.

Adverse Events Reported From Hyaluronic Acid Dermal Filler Injections to the Facial Region: A Systematic Review and Meta-Analysis.

Dermal filler injections are one of the most popular cosmetic procedures in the United States. Of the many options available, hyaluronic acid (HA) dermal fillers like Juvederm or Restylane are often used. Despite their use and popularity, adverse events are known to occur from these procedures. Although most outcomes may be mild and resolve over time, rare instances of severe complications cannot be ignored, as these effects may be irreversible. Healthcare practitioners and patients must be aware of these risks, as these cosmetic procedures can affect the patient's quality of life. The aim of this study was to evaluate the incidence of adverse events (AEs) reported from the use of hyaluronic acid dermal fillers in the facial region. A systemized search of randomized controlled trials was conducted using Cochrane Central, Embase, Medical Literature Analysis and Retrieval System Online (MEDLINE), and the Web of Science databases. After screening for eligibility and conducting a critical appraisal of the articles, 19 studies were retained for the final review. The meta-analysis results included different side effects by facial location, i.e., nasolabial fold (NLF) vs. other (midface, perioral line, and lip region). The midface includes the anteromedial cheek region, the zygomaticomalar region, and the submalar region. The adverse events were swelling, pain, erythema, bruising, lumps and bumps, firmness, tenderness, itching, and skin discoloration. A significant difference was found in the proportion of individuals experiencing swelling, lumps or bumps, and firmness at the nasolabial fold site versus the midface, perioral line, and lip region. There was no significant difference in the proportion of individuals experiencing pain, erythema, bruising, tenderness, itching, or skin discoloration at the nasolabial fold site versus the other sites. The study highlights the prevalence of common AEs that can result from HA dermal fillers like Juvederm or Restylane, thus emphasizing the importance of healthcare professionals explaining the risk and benefits to patients.

Glucocorticoid use in rheumatoid arthritis patients and the onset of pneumonia: a systematic review and meta-analysis.

CONTEXT: Rheumatoid arthritis (RA) is a systemic autoimmune disease that commonly affects joints. Although many treatment options exist, the most common, disease-modifying antirheumatic drugs (DMARDs), have been associated with pulmonary infections. These types of infections (specifically pneumonia) can be detrimental to RA patients. This leads providers to utilize other treatment modalities such as glucocorticoids (GCs). GCs are commonly utilized to treat RA; however, the role of GCs in the onset of pneumonia in RA patients is not fully understood. OBJECTIVES: The goal of this study was to systematically review and statistically analyze pooled data documenting pneumonia as an adverse event in RA patients on DMARDs as a monotherapy vs RA patients on DMARDs and GCs as combination therapy utilizing the Population, Intervention, Comparison, and Outcomes (PICO) framework. METHODS: On August 1, 2021, a search was conducted and completed on six databases: Embase, MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, International Pharmaceutical Abstracts (IPA), and ClinicalTrials.gov. A total of 12 researchers were involved with the search and screening of articles (K.E., P.R.; V.A., D.P.C.; C.B., D.C.; T.A., E.S.; S.H., L.B.; K.S., C.S.). Search terms were identified utilizing Medical Subject Headings (MeSH) and Emtree and included "glucocorticoids," "rheumatoid arthritis," "pneumonia," and "respiratory tract infections," Inclusion criteria included human subjects over the age of 18 with seropositive RA, on a combination of GC (prednisone, methylprednisolone, or prednisolone) with DMARD (methotrexate [MTX], hydroxychloroquine [HCQ], or sulfasalazine [SSZ]) and developed pneumonia of bacterial, viral, or fungal origin. The control groups were on a DMARD monotherapy regimen. Articles were excluded if they were not in English, had less than 20 participants, were case reports or literature reviews, included animal subjects, and did not adhere to the established PICO framework. Five teams of two researchers individually sorted through abstracts of articles based on the inclusion and exclusion criteria. The same teams individually sorted through full-text articles of selected abstracts based on the same criteria. Conflicts between each team were resolved by a separate researcher. Odds ratios were utilized to quantify the effect sizes of combined studies from a random effects model. Chi-square tests and I2 statistics were utilized to analyze heterogeneity. RESULTS: A total of 3360 articles were identified from all databases, and 416 duplicate articles were removed. Thus, a total of 2944 articles abstracts were screened, of which 2819 articles either did not meet the inclusion criteria or did meet the exclusion criteria. A total of 125 articles were retrieved and assessed for full-text eligibility, of which only three observational articles were included for meta-analysis. Statistical results revealed that patients treated with DMARDs monotherapy are 95% (95% CI: 0.65-0.99) less likely to develop pneumonia compared to patients treated with a DMARD and GCs (p=0.002). CONCLUSIONS: Our data suggest that RA patients have a higher probability of developing pneumonia on combination therapy with GCs, compared to monotherapy with DMARDs. To our knowledge, our findings are the first to systematically review and statistically evaluate the relationship between the use of GCs and show an increased chance of developing pneumonia.

Impact of Psychiatry Clerkship Rotation in Attitudes Towards Mental Illness and Psychiatry as a Career Among Medical Students.

Background: Stigma associated with mental illness (MI) permeates many professions, including healthcare. Recognizing and correcting bias is critical in delivering impartial and beneficial healthcare for all patients. Early educational interventions providing exposure to individuals with MI have shown to be effective at reducing MI stigma. The primary aim of our study was to assess the impact of a psychiatry clerkship on attitudes to MI. A secondary aim was to determine if the psychiatry clerkship influenced medical students' perceptions of psychiatry as a career. Methods: A cohort of third-year medical students in Florida was invited to complete an online survey before and after participating in their first 4-week-long psychiatry clerkship during the 2021-2022 academic year. The voluntary, anonymous survey consisted of the Attitudes to Mental Illness Questionnaire (AMIQ) and a 3-item questionnaire on interest and knowledge in psychiatry. The Wilcoxon Sign-Rank test was used to determine statistical significance (P < .05) for pre- and post-clerkship values. Results: Among 39 invited students, 22 participated before (56.4%), and 23 participated after their psychiatry rotation (59.0%). Overall, there was a statistically significant increase in the perceived level of general interest in psychiatry (P = .027), psychiatry knowledge (P < .001), and career interest in psychiatry (P = .040). There was also a significant decrease in the stigmatized attitude score for depression and self-harm after their psychiatry rotation (P = .042). Finally, the participants initially showed the highest stigmatized attitude score for intravenous drug abuse among the 4 mental illnesses presented, which also included depression and suicidal ideation, alcohol use disorder, and schizophrenia. Conclusion: The findings suggest that a psychiatry clerkship provided a positive exposure to the field, enhanced medical students' overall interest in psychiatry, and positively impacted medical students' attitudes towards MI.

Frictional wear of stud implant overdenture abutments after 2 years of in vitro simulated function.

Progressive wear of the components of an implant-supported overdenture can lead to loss of denture retention, which affects masticatory function and the patient's quality of life. The primary objective of this in vitro study was to investigate frictional wear in a type of commonly used abutment and thereby estimate the general clinical lifespan of a typical stud abutment and establish a protocol for replacement. Therefore, simulated overdenture insertions and removals equivalent to 2 years of overdenture use were performed to evaluate surface changes in the metal stud abutment component. A digital caliper, scanning electron micrographs taken at ×500 magnification, and profilometer data were used to determine the wear rate and surface roughness. A universal testing machine was used to measure retention load force with 4 clear male nylon inserts (5.0-lb retention) during 2160 insertion and removal cycles. The results showed that with a 6-month replacement program for clear male nylon inserts, the frictional wear on the titanium nitride coating of abutments placed at a 0° position resulted in a decrease of up to 50% in removal forces of the inserts after a simulated 2 years of wear. The combination of wear of the titanium nitride coating and the decrease in retention load values suggests that stud abutments should be replaced after 2 years of use for optimal retention.

Comorbidities and Symptomatology of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2)-Related Myocarditis and SARS-CoV-2 Vaccine-Related Myocarditis: A Review.

Myocarditis is an inflammatory disease of the heart muscle, with manifestations that include myocardial infarction, arrhythmia, and even sudden death. The primary etiology of myocarditis is a viral infection, with studies demonstrating that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to myocarditis. This enzyme is involved in many body tissues, including the gastrointestinal system and the cardiac system. This enzyme is responsible for converting angiotensin I to angiotensin II in the renin-angiotensin system of our body. This review aims to characterize the symptomatology and comorbidities of males, females, and pediatric patients who developed the SARS-CoV-2-related myocarditis (SARS-CoV-2RM) or the SARS-CoV-2 vaccine-related myocarditis (SARS-CoV-2VRM). From July 10 to July 20, 2021, a PubMed database search for "SARS CoV-2 Related Myocarditis" was conducted. From July 21 to July 30, 2021, the search for "SARS CoV-2 Vaccine Related Myocarditis" was conducted. The search completed was specific for title/abstract fields using keywords "Covid-19" AND "Myocarditis" AND "Vaccine" and specifying "Males" or "Females", respectively. Inclusion criteria included articles discussing comorbidities and symptomatology. Exclusion criteria included autopsy/postmortem reports, letters to the editor, retrospective studies, and observational studies. In the end, 49 articles were found and included in this review. We found that 27 of 40 pediatric patients with SARS-CoV-2RM presented with gastrointestinal symptoms, and 12 of 40 pediatric patients had no comorbidities. In female cases, eight of 12 patients with SARS-CoV-2RM presented with noncardiac symptoms, and only four of 12 had comorbidities such as asthma, diabetes, and obesity. In male patients with SARS-CoV-2RM, 10 of 12 presented with respiratory and/or cardiac symptoms, and seven of 12 had cardiac and/or diabetic comorbidities. Furthermore, 22 of 31 male patients with SARS-CoV-2VRM presented with chest pain with no previous comorbidities; four of six females with SARS-CoV-2VRM presented with chest pain, and three of six females had no comorbidities; and seven of 11 pediatric patients with SARS-CoV-2VRM had no comorbidities, but 11 of 11 pediatric patients presented with chest pain. In conclusion, males, females, and pediatric patients with previous SARS-CoV-2VRM showed mostly chest pain with no comorbidities. Males presenting with SARS-CoV-2RM showed mostly respiratory and cardiac symptoms with cardiac and diabetic comorbidities. Females with SARS-CoV-2RM described various symptoms from flu-like, respiratory, to cardiac and had no previous comorbidities. The bulk of pediatric patients with SARS-CoV-2RM mainly presented with GI symptoms and no past comorbidities. More studies are needed to determine the clinical presentation and risk factors that lead to SARS-CoV-2RM and SARS-CoV-2VRM.

Locally Secreted Semaphorin 4D Is Engaged in Both Pathogenic Bone Resorption and Retarded Bone Regeneration in a Ligature-Induced Mouse Model of Periodontitis.

It is well known that Semaphorin 4D (Sema4D) inhibits IGF-1-mediated osteogenesis by binding with PlexinB1 expressed on osteoblasts. However, its elevated level in the gingival crevice fluid of periodontitis patients and the broader scope of its activities in the context of potential upregulation of osteoclast-mediated periodontal bone-resorption suggest the need for further investigation of this multifaceted molecule. In short, the pathophysiological role of Sema4D in periodontitis requires further study. Accordingly, attachment of the ligature to the maxillary molar of mice for 7 days induced alveolar bone-resorption accompanied by locally elevated, soluble Sema4D (sSema4D), TNF-α and RANKL. Removal of the ligature induced spontaneous bone regeneration during the following 14 days, which was significantly promoted by anti-Sema4D-mAb administration. Anti-Sema4D-mAb was also suppressed in vitro osteoclastogenesis and pit formation by RANKL-stimulated BMMCs. While anti-Sema4D-mAb downmodulated the bone-resorption induced in mouse periodontitis, it neither affected local production of TNF-α and RANKL nor systemic skeletal bone remodeling. RANKL-induced osteoclastogenesis and resorptive activity were also suppressed by blocking of CD72, but not Plexin B2, suggesting that sSema4D released by osteoclasts promotes osteoclastogenesis via ligation to CD72 receptor. Overall, our data indicated that ssSema4D released by osteoclasts may play a dual function by decreasing bone formation, while upregulating bone-resorption.

Dual-Function Semaphorin 4D Released by Platelets: Suppression of Osteoblastogenesis and Promotion of Osteoclastogenesis.

Effects of the antiosteoblastogenesis factor Semaphorin 4D (Sema4D), expressed by thrombin-activated platelets (TPs), on osteoblastogenesis, as well as osteoclastogenesis, were investigated in vitro. Intact platelets released both Sema4D and IGF-1. However, in response to stimulation with thrombin, platelets upregulated the release of Sema4D, but not IGF-1. Anti-Sema4D-neutralizing monoclonal antibody (mAb) upregulated TP-mediated osteoblastogenesis in MC3T3-E1 osteoblast precursors. MC3T3-E1 cells exposed to TPs induced phosphorylation of Akt and ERK further upregulated by the addition of anti-sema4D-mAb, suggesting the suppressive effects of TP-expressing Sema4D on osteoblastogenesis. On the other hand, TPs promoted RANKL-mediated osteoclastogenesis in the primary culture of bone-marrow-derived mononuclear cells (BMMCs). Among the known three receptors of Sema4D, including Plexin B1, Plexin B2 and CD72, little Plexin B2 was detected, and no Plexin B1 was detected, but a high level of CD72 mRNA was detected in RANKL-stimulated BMMCs by qPCR. Both anti-Sema4D-mAb and anti-CD72-mAb suppressed RANKL-induced osteoclast formation and bone resorptive activity, suggesting that Sema4D released by TPs promotes osteoclastogenesis via ligation to a CD72 receptor. This study demonstrated that Sema4D released by TPs suppresses osteogenic activity and promotes osteoclastogenesis, suggesting the novel property of platelets in bone-remodeling processes.

Associations of Stay-at-Home Order Enforcement With COVID-19 Population Outcomes: An Interstate Statistical Analysis.

In the United States, state governors initially enacted coronavirus diseases 2019 (COVID-19)-mitigation policies with limited epidemiologic data. One prevailing legislative approach, from March to May 2020, was the implementation of "stay-at-home" (SAH) executive orders. Although social distancing was encouraged, SAH orders varied between states, and the associations between potential legal prosecution and COVID-19 outcomes are currently unknown. Here, we provide empirical evidence on how executive enforcement of movement restrictions may influence population health during an infectious disease outbreak. A generalized linear model with negative binomial regression family compared COVID-19 outcomes in states with law-enforceable stay-at-home (eSAH) orders versus those with unenforceable or no SAH orders (uSAH), controlling for demographic factors, socioeconomic influences, health comorbidities, and social distancing. COVID-19 incidence was less by 1.22 cases per day per capita in eSAH states compared with uSAH states (coefficient = -1.22, 95% confidence interval (CI): -1.83, -0.61; P < 0.001), and each subsequent day without an eSAH order was associated with a 0.03 incidence increase (coefficient = 0.03, 95% CI: 0.03, 0.04; P < 0.001). Daily mortality was 1.96 less for eSAH states per capita (coefficient = -1.96, 95% CI: -3.25, -0.68; P = 0.004). Our findings suggest allowing the enforcement of public health violations, compared with community education alone, is predictive of improved COVID-19 outcomes.

Trends in liver profile and nutrition outcomes in children undergoing intestinal rehabilitation using a mixed lipid injectable emulsion.

BACKGROUND: Pediatric patients undergoing intestinal rehabilitation (IR) using parenteral nutrition (PN) are at higher risk for intestinal failure-associated liver disease (IFALD). Nutrition support, growth, and liver enzymes must be closely monitored while incorporating hepatoprotective lipid injectable emulsions for optimal patient outcomes. OBJECTIVE: Describe trends of liver profile and nutrition outcomes for pediatric patients undergoing IR using SMOFlipid[SO,MCT,OO,FO-ILE]). METHODS: After IRB approval, patients undergoing IR using SO,MCT,OO,FO-ILE were observed prospectively from January 1, 2017, through December 1, 2019. The following values were documented monthly: aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TB), triene/tetraene ratio (TTR), micronutrient and trace element levels, z-scores for growth, and nutrition support regimen. Values were compared. RESULTS: The group involved 16 pediatric patients for an average of 16.4 months on SO,MCT,OO,FO-ILE. By the end of the study, mean PN hours per day decreased by 34.7%, P < 0.0001. Mean PN calories per kilogram decreased from 60.4 to 48.3, P = 0.004. SO,MCT,OO,FO-ILE calories met the recommended dietary intake goal of 30% at the average 1.6 g/kg. Growth z-scores increased in those <2 YOA , although the body mass index decreased in our >2 YOA cohort. Total nutrition received from PN decreased to 62%: a 32% change, P = 0.001. There were no statistically significant changes in AST or ALT. TB decreased by 67.08%, P <0.05. No essential fatty acid deficiency was reported (TTR < 0.02). There were no changes in micronutrient and trace element deficiencies. There was zero new incidences of IFALD. CONCLUSIONS: SO,MCT,OO,FO-ILE may be used long term in pediatric patients while promoting growth and development.

A Case-Control Study for the Effectiveness of Oral Zinc in the Prevention and Mitigation of COVID-19.

Background: The ongoing coronavirus disease-19 (COVID-19) pandemic (caused by an infection with severe acute respiratory syndrome (SARS)-coronavirus (CoV-2) has put a burden on the medical community and society at large. Efforts to reduce the disease burden and mortality over the course of the pandemic have focused on research to rapidly determine age-stratified seroepidemiologic surveys, a centralized research program to fast-track the most promising rapid diagnostics and serologic assays, and the testing of potential anti-viral agents, immunologic therapies, and vaccine candidates. Despite the lack of official recognition for the role of nutrition in the fight against COVID-19 infection, multiple groups proposed zinc supplementation as an adjuvant for the management of participants. Method: In an ambulatory, interventional, prospective, single-blind study, we evaluated the effectiveness of zinc supplementation in the prevention and mitigation of COVID-19 in two similar participant groups. In Clinic A (n = 104) participants were randomized to receive 10 mg, 25 mg, or 50 mg zinc picolinate daily, and Clinic B control participants paired according to their demographics and clinical parameters (n = 96). All participants were compared based on demographics, clinical comorbidities, blood counts, renal functions, vitamin D levels, and their development of symptomatic COVID-19 infection. Results: Symptomatic COVID-19 infection was significantly higher among the control group participants (N = 9, 10.4%) than the treatment participants (N = 2, 1.9%), p = 0.015. The unadjusted odds ratio indicates that symptomatic COVID-19 infection was 5.93 [95% CI: 1.51, 39.26] higher in the control group, p < 0.01. Controlling for co-morbidities, individuals in the control group were 7.38 (95% CI: 1.80, 50.28) times more likely to develop symptomatic COVID-19 infection as compared with individuals in the treatment group (p < 0.01). For every-one unit increase in the number of co-morbidities, the likelihood of developing symptomatic COVID-19 infection increased 1.57 (95% CI: 1.16, 2.19) (p = 0.01). Discussion: The findings from our study suggest that zinc supplementation in all three doses (10, 25, and 50 mg) may be an effective prophylaxis of symptomatic COVID-19 and may mitigate the severity of COVID-19 infection. Conclusion: Zinc is a relatively inexpensive mineral nutrient that is an effective prophylactic agent to prevent and mitigate the potentially deadly symptomatic SARS-CoV-2 infection. As the COVID-19 pandemic continues with a lag in vaccinations in some regions and the continued emergence of dangerously infectious variants of SARS-CoV-2, it is important to replicate our data in other populations and locations and to engage public health and nutrition services on the emergent need to use zinc supplantation or fortification of staple foods in the prevention and mitigation of COVID-19 infection severity.

Improving Antioxidant Capacity in Children With Autism: A Randomized, Double-Blind Controlled Study With Cysteine-Rich Whey Protein.

Previous studies indicate that children with autism spectrum disorder (ASD) have lower levels of glutathione. Nutritional interventions aim to increase glutathione levels suggest a positive effect on ASD behaviors, but findings are mixed or non-significant. A commercially available nutritional supplement comprising a cysteine-rich whey protein isolate (CRWP), a potent precursor of glutathione, was previously found to be safe and effective at raising glutathione in several conditions associated with low antioxidant capacity. Therefore, we investigated the effectiveness of a 90-day CRWP intervention in children with ASD and examined whether intracellular reduced and oxidized glutathione improvements correlated with behavioral changes. We enrolled 46 (of 81 screened) 3-5-year-old preschool children with confirmed ASD. Using a double-blind, randomized, placebo-controlled design, we evaluated the effectiveness of daily CRWP (powder form: 0.5 g/kg for children <20 kg or a 10-g dose for those >20 kg), compared with placebo (rice protein mimicking the protein load in the intervention group), on glutathione levels and ASD behaviors assessed using different behavioral scales such as Childhood Autism Rated Scale, Preschool Language Scale, Social Communication Questionnaire, Childhood Behavioral Checklist and the parent-rated Vineland Adaptive Behavior Scale, 2nd edition (VABS-II). Forty children (CRWP, 21; placebo, 19) completed the 90-day treatment period. Improvements observed in some behavioral scales were comparable. However, the VABS-II behavioral assessment, demonstrated significant changes only in children receiving CRWP compared to those observed in the placebo group in the composite score (effect size 0.98; 95% confidence intervals 1.42-4.02; p = 0.03). Further, several VABS-II domain scores such as adaptive behavior (p = 0.03), socialization (p = 0.03), maladaptive behavior (p = 0.04) and internalizing behavior (p = 0.02) also indicated significant changes. Children assigned to the CRWP group showed significant increases in glutathione levels (p = 0.04) compared to those in the placebo group. A subanalysis of the VABS-II scale results comparing responders (>1 SD change from baseline to follow up) and non-responders in the CRWP group identified older age and higher levels of total and reduced glutathione as factors associated with a response. CRWP nutritional intervention in children with ASD significantly improved both glutathione levels and some behaviors associated with ASD. Further studies are needed to confirm these results.

Gender and Pharmacists' Career Satisfaction in the United States.

Job satisfaction reflects pharmacists' evaluation of their current work experiences, while career satisfaction is an evaluation of how satisfied pharmacists are with their profession across various jobs. The objectives of this article were to measure career satisfaction and specific facets of current-job satisfaction of U.S. pharmacists, compare satisfaction across genders, and examine the determinants of career satisfaction. This study was based on self-reported survey data collected from a random sample of licensed pharmacists practicing throughout the United States. The sample consisted of 422 men and 315 women. Within each gender, pharmacists' career satisfaction was modeled using ordinary least squares as a function of three sets of variables: personal characteristics, earnings and workweek, and other job-related variables. Female pharmacists exhibited higher levels of contentment with their careers than their male counterparts. Their career-satisfaction levels were not affected by age, marital status, annual earnings, or average workweek, covariates that systematically influenced male pharmacists' career satisfaction. Job satisfaction substantially affected pharmacists' long-term career satisfaction. Male and female pharmacists responded differently to stimuli, so a uniform set of work-related incentives may not be effective for both genders. Initiatives perceived by male practitioners as increasing satisfaction may be adversely perceived by female practitioners, and vice-versa.

Managed care COVID-19 outcomes in a population health program.

OBJECTIVES: To determine (1) factors linked to hospitalizations among managed care patients (MCPs), (2) outcome improvement with use of outpatient off-label treatment, and (3) outcome comparison between MCPs and a mirror group. STUDY DESIGN: Retrospective cohort study comparing MCPs with an age- and gender-matched mirror group in Florida from April 1, 2020, to May 31, 2020. METHODS: A total of 38,193 MCPs in a Florida primary care group were monitored for COVID-19 incidence, hospitalization, and mortality. The highest-risk patients were managed by the medical group's COVID-19 Task Force. As part of a population health program, the COVID-19 Task Force contacted patients, conducted medical encounters, and tracked data including comorbidities and medical outcomes. The MCPs enrolled in the medical group were compared with a mirror group from the state of Florida. RESULTS: The mean (SD) age among the MCPs was 67.9 (15.2) years, and 60% were female. Older age and hypertension were the most important factors in predicting COVID-19. Obesity, chronic kidney disease (CKD), and congestive heart failure (CHF) were linked to higher rates of hospitalizations. Patients prescribed off-label outpatient medications had 73% lower likelihood of hospitalization (P < .05). Compared with the mirror group, MCPs had 60% lower COVID-19 mortality (P < .05). CONCLUSIONS: MCPs have risk factors similar to the general population for COVID-19 incidence and progression, including older age, hypertension, obesity, CHF, and CKD. Outpatient treatment with off-label medicines decreased hospitalizations. A comprehensive population health program decreased COVID-19 mortality.

Immunogenicity of The Influenza Vaccine in Multiple Sclerosis Patients: A Systematic Review and Meta-Analysis.

OBJECTIVE: Multiple sclerosis is a neurodegenerative disease thought to be of autoimmune origin. It can lead to development of neurological symptoms and increase the risk of infection from communicable diseases. Thus, vaccines are endorsed to mitigate this risk. However, it has not yet been confirmed whether the dysfunctional immune system of these patients combined with taking immunosuppressants can lead to a dampened immunity in response to the influenza vaccine. Infection with the influenza virus is a concern for multiple sclerosis patients. Previous research on multiple sclerosis patients who have received the influenza vaccine focuses on safety and relapse rates. Studies that focus on the immune response mounted against the vaccine in this patient cohort are scant. This study serves to provide a comprehensive picture of the immunogenicity of the influenza vaccine in MS patients. METHODS: A systematic review of compiled research was conducted. Data obtained from the research was used in a meta-analysis using risk differences with a 95% confidence interval. RESULTS: Across the various strains incorporated into the influenza vaccine analyzed in this paper, there was no statistical difference in immune response mounted against the influenza vaccine between healthy controls and multiple sclerosis patients. CONCLUSION: The results of this study suggest that multiple sclerosis patients can mount an adequate immune response to the influenza vaccine when compared to healthy controls. Most of the immunotherapies these patients are on do not appear to affect this immune response. Therefore, the influenza vaccine should continue to be recommended to multiple sclerosis patients.

Accuracy of Detecting Atrial Fibrillation: A Systematic Review and Meta-Analysis of Wrist-Worn Wearable Technology.

Atrial fibrillation (AF) is the most commonly diagnosed arrhythmia, and ECG remains the gold standard for diagnosing AF. Wrist-worn technologies are appealing for their ability to passively process near-continuous pulse signals. The clinical application of wearable devices is controversial. Our systematic review and meta-analysis qualitatively and quantitatively analyze available literature on wrist-worn wearable devices (Apple Watch, Samsung, and KardiaBand) and their sensitivity and specificity in detecting AF compared to conventional methods. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, yielding nine studies (n = 1,581). Observational studies assessing the sensitivity and specificity of wrist-worn wearables in detecting AF in patients with and without a history of AF were included and analyzed using a fixed-effect model with an inverse-variance method. In patients with a history of AF, the overall sensitivity between device groups did not significantly differ (96.83%; P = 0.207). Specificity significantly differed between Apple, Samsung, and KardiaBand (99.61%, 81.13%, and 97.98%, respectively; P<0.001). The effect size for this analysis was highest in the Samsung device group. Two studies (n = 796) differentiated cohorts to assess device sensitivity in patients with known AF and device specificity in patients with normal sinus rhythm (NSR) (sensitivity: 96.02%; confidence intervals (CI) 93.85%-97.59% and specificity: 98.82%; CI:97.46%-99.57%). Wrist-worn wearable devices demonstrate promising results in detecting AF in patients with paroxysmal AF. However, more rigorous prospective data is needed to understand the limitations of these devices in regard to varying specificities which may lead to unintended downstream medical testing and costs.

Influence of BMI percentile on craniofacial morphology and development in children and adolescents.

BACKGROUND: The prevalence of childhood and adolescent obesity is increasing worldwide. Reports suggest that elevated body mass index (BMI) is associated with larger craniofacial dimensions and advanced dental and skeletal development. Such an association is important for timing orthodontic treatment relative to pubertal growth and dental eruption. MATERIALS AND METHODS: To evaluate associations between BMI, craniofacial morphology, dental age, and cervical vertebrae maturation staging (CVMS), 400 participants were consecutively selected (8-15 years, n = 200 overweight and obese BMI >85%, 200 normal weight) from the University of North Carolina database. Records were analysed for cephalometric measures, Demirjian index values, and CVMS. Bivariate statistics and linear regression analysis evaluated whether CVMS, dental age, and cephalometric dimensions varied with BMI. RESULTS: Overweight/obese children and adolescents had a proportionally larger bimaxillary prognathic skeletal pattern compared to those of normal weight. These cephalometric measurements [articulare-gnathion (Ar-Gn), condylion-anterior nasal spine (Co-ANS), sella-gonion (S-Go), nasion-menton (N-Me), anterior nasal spine-menton (ANS-Me), sella-nasion-A point (SNA), sella-nasion-B point (SNB), and sella-nasion-pogonion (SNPg)] were significantly different [statistically (P < 0.05) and clinically (>2 mm or >2 degrees)] between the two study groups, with a linear relationship between BMI percentile and craniofacial dimension. The overweight/obese BMI group had a mean dental age 1.4 years advanced relative to the normal weight group (P < 0.05), with an advancement of nearly one CVM stage between the ages of 12 and 14 (P < 0.05). LIMITATIONS: The study is retrospective. CONCLUSIONS: Obese/overweight children and adolescents have proportionally larger antero-posterior and vertical dimensions and are more likely to experience advanced dental and skeletal maturation. Obese/overweight subjects may enter their growth spurt at a younger age and have earlier eruption of teeth, affecting treatment timing. BMI percentile should be a consideration for orthodontic treatment in growing patients.

Current Understanding of COVID-19 Clinical Course and Investigational Treatments.

Importance: Currently, there is no unified framework linking disease progression to established viral levels, clinical tests, inflammatory markers, and investigational treatment options. Objective: It may take many weeks or months to establish a standard treatment approach. Given the growing morbidity and mortality with respect to COVID-19, this systemic review presents a treatment approach based on a thorough review of scholarly articles and clinical reports. Our focus is on staged progression, clinical algorithms, and individualized treatment. Evidence Review: We followed the protocol for a quality review article proposed by Heyn et al. (1). A literature search was conducted to find all relevant studies related to COVID-19. The search was conducted between April 1, 2020, and April 13, 2020, using the following electronic databases: PubMed (1809 to present); Google Scholar (1900 to present); MEDLINE (1946 to present), CINAHL (1937 to present); and Embase (1980 to present). The keywords used included COVID-19, 2019-nCov, SARS-CoV-2, SARS-CoV, and MERS-CoV, with terms such as efficacy, seroconversion, microbiology, pathophysiology, viral levels, inflammation, survivability, and treatment and pharmacology. No language restriction was placed on the search. Reference lists were manually scanned for additional studies. Findings: Of the articles found in the literature search, 70 were selected for inclusion in this study (67 cited in the body of the manuscript and 3 additional unique references in the Figures). The articles represent work from China, Japan, Taiwan, Vietnam, Rwanda, Israel, France, the United Kingdom, the Netherlands, Canada, and the United States. Most of the articles were cohort or case studies, but we also drew upon other information, including guidelines from hospitals and clinics instructing their staff on procedures to follow. In addition, we based some decisions on data collected by organizations such as the CDC, FDA, IHME, IDSA, and Worldometer. None of the case studies or cohort studies used a large number of participants. The largest group of participants numbered <500 and some case studies had fewer than 30 patients. However, the review of the literature revealed the need for individualized treatment protocols due to the variability of patient clinical presentation and survivability. A number of factors appear to influence mortality: the stage at which the patient first presented for care, pre-existing health conditions, age, and the viral load the patient carried. Conclusion and Relevance: COVID-19 can be divided into three distinct stages, beginning at the time of infection (Stage I), sometimes progressing to pulmonary involvement (Stage II, with or without hypoxemia), and less frequently to systemic inflammation (Stage III). In addition to modeling the stages of disease progression along with diagnostic testing, we have also created a treatment algorithm that considers age, comorbidities, clinical presentation, and disease progression to suggest drug classes or treatment modalities. This paper presents the first evidence-based recommendations for individualized treatment for COVID-19.
