RESUMO
Corneal confocal microscopy (CCM) is an ophthalmic imaging technique that enables the identification of corneal nerve fibre degeneration and regeneration. To undertake a systematic review and meta-analysis of studies utilizing CCM to assess for corneal nerve regeneration after pharmacological and surgical interventions in patients with peripheral neuropathy. Databases (EMBASE [Ovid], PubMed, CENTRAL and Web of Science) were searched to summarize the evidence from randomized and non-randomized studies using CCM to detect corneal nerve regeneration after pharmacological and surgical interventions. Data synthesis was undertaken using RevMan web. Eighteen studies including 958 patients were included. CCM identified an early (1-8 months) and longer term (1-5 years) increase in corneal nerve measures in patients with peripheral neuropathy after pharmacological and surgical interventions. This meta-analysis confirms the utility of CCM to identify nerve regeneration following pharmacological and surgical interventions. It could be utilized to show a benefit in clinical trials of disease modifying therapies for peripheral neuropathy.

Obsessive-compulsive disorder (OCD) is a debilitating mental health disorder characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions). Dysbiosis, an imbalance in the gut microbial composition, has been associated with various health conditions, including mental health disorders, autism, and inflammatory diseases. While the exact mechanisms underlying OCD remain unclear, this review presents a growing body of evidence suggesting a potential link between dysbiosis and the multifaceted etiology of OCD, interacting with genetic, neurobiological, immunological, and environmental factors. This review highlights the emerging evidence implicating the gut microbiota in the pathophysiology of OCD and its potential as a target for novel therapeutic approaches. We propose a model that positions dysbiosis as the central unifying element in the neurochemical, immunological, genetic, and environmental factors leading to OCD. The potential and challenges of microbial reprogramming strategies, such as probiotics and fecal transplants in OCD therapeutics, are discussed. This review raises awareness of the importance of adopting a holistic approach that considers the interplay between the gut and the brain to develop interventions that account for the multifaceted nature of OCD and contribute to the advancement of more personalized approaches.
RESUMO
BACKGROUND: Hepatitis C virus (HCV) is a major public health problem in correctional settings. HCV treatment is often not possible in U.S. jails due to short lengths of stay. Linkage to care is crucial in these settings, but competing priorities complicate community healthcare engagement and retention after incarceration. METHODS: We conducted a single arm clinical trial of a combined transitional care coordination (TCC) and patient navigation intervention and assessed the linkage rate and factors associated with linkage to HCV care after incarceration. RESULTS: During the intervention, 84 participants returned to the community after their index incarceration. Most participants were male and Hispanic, with a history of mental illness and a mean age of 45 years. Of those who returned to the community, 26 (31%) linked to HCV care within a median of 20.5 days; 17 (20%) initiated HCV treatment, 15 (18%) completed treatment, 9 (11%) had a follow-up lab drawn to confirm sustained virologic response (SVR), and 7 (8%) had a documented SVR. Among those with follow-up labs the known SVR rate was (7/9) 78%. Expressing a preference to be linked to the participant's existing health system, being on methadone prior to incarceration, and feeling that family or a loved one were concerned about the participant's wellbeing were associated with linkage to HCV care. Reporting drinking alcohol to intoxication prior to incarceration was negatively associated with linkage to HCV care. CONCLUSION: We demonstrate that an integrated strategy with combined TCC and patient navigation may be effective in achieving timely linkage to HCV care. Additional multicomponent interventions aimed at treatment of substance use disorders and increasing social support could lead to further improvement. TRIAL REGISTRATION: Clinicaltrials.gov NCT04036760 July 30th, 2019 (retrospectively registered).

Objective: To quantify the extent to which co-morbid FM is associated with higher disease activity, worse quality of life (QoL) and poorer response to TNF inhibitors (TNFis) in patients with axial SpA. Methods: A prospective study recruiting across 83 centres in the UK. Clinical information and patient-reported measures were available, including 2011 criteria for FM. Multivariable linear regression was used to model the effect of meeting the FM criteria on disease activity, QoL and response to TNFis. Results: A total of 1757 participants were eligible for analyses, of whom 22.1% met criteria for FM. Those with co-morbid FM criteria had higher disease activity [BASDAI average difference FM+ - FM- 1.04 (95% CI 0.75, 1.33)] and worse QoL [Ankylosing Spondylitis Quality of Life score difference 1.42 (95% CI 0.88, 1.96)] after adjusting for demographic, clinical and lifestyle factors. Among 291 participants who commenced biologic therapy, BASDAI scores in those with co-morbid FM were 2.0 higher at baseline but decreased to 1.1 higher at 12 months. There was no significant difference in the likelihood of meeting Assessment of SpondyloArthritis international Society 20 criteria at 12 months. Less improvement in disease activity and QoL over 3 months of TNFi therapy was most strongly related to high scores on the FM criteria symptom severity scale component. Conclusion: Fulfilling criteria for FM has a modest impact on the assessment of axial SpA disease activity and QoL and does not significantly influence response to biologic therapy. Those with a high symptom severity scale on FM assessment may benefit from additional specific management for FM.

OBJECTIVES: To examine uptake of screening for all individuals born between 1945 and 1965 (referred to by the Centers for Disease Control and Prevention as the "birth cohort") and outline preliminary HCV prevalence data in the New York City jail system. METHODS: Data were extracted from electronic health records for all individuals screened for HCV between June 13, 2013, and June 13, 2014, in New York City jails. We used the Abbott EIA 2.0 HCV antibody assay for testing. RESULTS: In the year of study, 56 590 individuals were incarcerated; 15.1% were born between 1945 and 1965, and 84.6% were born after 1965. HCV screening was completed for 64.1% of the birth cohort and for 11.1% born after 1965, with 55.1% and 43.8% of cases found in these groups, respectively. The overall seropositivity rate was 20.6%. CONCLUSIONS: Birth cohort screening in a large jail system identified many HCV cases, but HCV infection was common among younger age groups. PUBLIC HEALTH IMPLICATIONS: Universal screening may be warranted pending further study including cost-effectiveness analyses.

OBJECTIVES: We used "hot spotting" to characterize the persons most frequently admitted to the New York City jail system in 2013. METHODS: We used our Correctional Health Services electronic health record to identify 800 patients admitted in 2013 who returned most since November 2008. We compared them to a randomly selected control group of 800 others admitted in 2013, by using descriptive statistics and cross-tabulations, including data through December 2014. RESULTS: The frequently incarcerated individuals had a median of 21 incarcerations (median duration 11 days), representing 18 713 admissions and $129 million in custody and health costs versus $38 million for the controls. The frequently incarcerated were significantly older (42 vs 35 years), and more likely to have serious mental illness (19% vs 8.5%) and homelessness (51.5% vs 14.7%) in their record. Significant substance use was highly prevalent (96.9% vs 55.6%). Most top criminal charges (88.7%) for the frequently incarcerated were misdemeanors; assault charges were less common (2.8% vs 10.4%). CONCLUSIONS: Frequently incarcerated persons have chronic mental health and substance use problems, their charges are generally minor, and incarceration is costly. Tailored supportive housing is likely to be less costly and improve outcomes.

OBJECTIVES: To better understand jail mental health services entry, we analyzed diagnosis timing relative to solitary confinement, nature of diagnosis, age, and race/ethnicity. METHODS: We analyzed 2011 to 2013 medical records on 45,189 New York City jail first-time admissions. RESULTS: Of this cohort, 21.2% were aged 21 years or younger, 46.0% were Hispanic, 40.6% were non-Hispanic Black, 8.8% were non-Hispanic White, and 3.9% experienced solitary confinement. Overall, 14.8% received a mental health diagnosis, which was associated with longer average jail stays (120 vs 48 days), higher rates of solitary confinement (13.1% vs 3.9%), and injury (25.4% vs 7.1%). Individuals aged 21 years or younger were less likely than older individuals to receive a mental health diagnosis (odds ratio [OR] = 0.86; 95% confidence interval [CI] = 0.80, 0.93; P < .05) and more likely to experience solitary confinement (OR = 4.99; 95% CI = 4.43, 5.61; P < .05). Blacks and Hispanics were less likely than Whites to enter the mental health service (OR = 0.57; 95% CI = 0.52, 0.63; and OR = 0.49; 95% CI = 0.44, 0.53; respectively; P < .05), but more likely to experience solitary confinement (OR = 2.52; 95% CI = 1.88, 3.83; and OR = 1.65; 95% CI = 1.23, 2.22; respectively; P < .05). CONCLUSIONS: More consideration is needed of race/ethnicity and age in understanding and addressing the punishment and treatment balance in jails.

OBJECTIVES: We sought to better understand acts of self-harm among inmates in correctional institutions. METHODS: We analyzed data from medical records on 244 699 incarcerations in the New York City jail system from January 1, 2010, through January 31, 2013. RESULTS: In 1303 (0.05%) of these incarcerations, 2182 acts of self-harm were committed, (103 potentially fatal and 7 fatal). Although only 7.3% of admissions included any solitary confinement, 53.3% of acts of self-harm and 45.0% of acts of potentially fatal self-harm occurred within this group. After we controlled for gender, age, race/ethnicity, serious mental illness, and length of stay, we found self-harm to be associated significantly with being in solitary confinement at least once, serious mental illness, being aged 18 years or younger, and being Latino or White, regardless of gender. CONCLUSIONS: These self-harm predictors are consistent with our clinical impressions as jail health service managers. Because of this concern, the New York City jail system has modified its practices to direct inmates with mental illness who violate jail rules to more clinical settings and eliminate solitary confinement for those with serious mental illness.

OBJECTIVES: Clinical research professionals must be equipped with adequate training in sound scientific methods and appropriate ethics. In this study, we aimed to assess the current clinical research self-efficacy of researchers at Hamad Medical Corporation (HMC). We also evaluated the effects of training courses on researchers' self-efficacy. METHODS: Utilizing a cross-sectional design, we used the shortened Clinical Research Appraisal Inventory (CRAI-12) through an online survey to assess the current clinical research self-efficacy of 600 researchers at HMC, Doha, Qatar. After conducting descriptive analyses, unpaired t test and ANOVA were used to determine significant mean percentages between variables. Pearson correlation coefficients were also calculated to measure the association among the interval variables. All tests were 2-sided, and significance was defined as P < .05. RESULTS: For all questions, except those related to "funding," most participants scored on the upper half of the scale (>5), reflecting higher self-efficacy for the topics covered in CRAI. Gender differences were significant across all factors, with males reporting higher levels of self-assessed efficacy and in clinical research. Other factors such as higher education degrees and previous (external) clinical research training were also associated with higher self-reported clinical research efficacy. CONCLUSIONS: The findings of this study indicate that researchers at HMC possess high clinical research self-efficacy overall, but lower self-efficacy in securing funding. Gender and education level positively influence self-efficacy across CRAI factors. Notably, clinical research training boosts self-efficacy, especially when obtained outside HMC. In conclusion, healthcare providers are strongly encouraged to engage in effective clinical research training courses, both within and outside of their healthcare institutions, to improve their clinical research efficacy and enhance clinical practice.
RESUMO
Introduction: There are scant data on implementation of large-scale direct-acting antiviral treatment for hepatitis C virus in jails in the U.S. New York City Health + Hospitals/Correctional Health Services aimed to scale up hepatitis C virus treatment in the New York City jail system. This study describes the trends in annual hepatitis C virus treatment in New York City jails compared with those in Medicaid-funded treatment in the New York City community from 2014 to 2020. Methods: In this observational study, we extracted annual counts of direct-acting antiviral prescriptions for hepatitis C virus for those (1) in the New York City community who were covered by Medicaid and (2) those detained in New York City jails for 2014-2020. Data sources were New York City Department of Health and Mental Hygiene annual reports and Correctional Health Services treatment records, respectively. We used linear regression analysis to test for significant trends in annual treatment in these 2 cohorts during 2015-2019. Results: From 2015 to 2019, treatments started in New York City jails increased annually (p=0.001), whereas Medicaid-funded prescriptions in the New York City community declined since a peak in 2015 (p<0.001). In 2019, New York City jail-based treatment initiations totaled the equivalent of 10% of treatment covered by Medicaid in New York City, up from 0.3% in 2015. Conclusions: Scale up of jail-based hepatitis C virus treatment is an important strategy to offset declines observed in the community. Addressing barriers to care in jail, such as improving testing, linkage to care, and affordability of direct-acting antivirals for jail-based health services, can help sustain high levels of treatment in U.S. jails and other carceral facilities.
RESUMO
Metformin is an orally effective anti-hyperglycemic drug that despite being introduced over 60 years ago is still utilized by an estimated 120 to 150 million people worldwide for the treatment of type 2 diabetes (T2D). Metformin is used off-label for the treatment of polycystic ovary syndrome (PCOS) and for pre-diabetes and weight loss. Metformin is a safe, inexpensive drug with side effects mostly limited to gastrointestinal issues. Prospective clinical data from the United Kingdom Prospective Diabetes Study (UKPDS), completed in 1998, demonstrated that metformin not only has excellent therapeutic efficacy as an anti-diabetes drug but also that good glycemic control reduced the risk of micro- and macro-vascular complications, especially in obese patients and thereby reduced the risk of diabetes-associated cardiovascular disease (CVD). Based on a long history of clinical use and an excellent safety record metformin has been investigated to be repurposed for numerous other diseases including as an anti-aging agent, Alzheimer's disease and other dementias, cancer, COVID-19 and also atrial fibrillation (AF). AF is the most frequently diagnosed cardiac arrythmia and its prevalence is increasing globally as the population ages. The argument for repurposing metformin for AF is based on a combination of retrospective clinical data and in vivo and in vitro pre-clinical laboratory studies. In this review, we critically evaluate the evidence that metformin has cardioprotective actions and assess whether the clinical and pre-clinical evidence support the use of metformin to reduce the risk and treat AF.

BACKGROUND: Treatment with methadone and buprenorphine medications for opioid use disorder (MOUD) during incarceration may lead to better community re-entry, but evidence on these relationships have been mixed. We aimed to identify community re-entry patterns and examine the association between in-jail MOUD and a pattern of successful reentry defined by rare occurrence of reincarceration and preventable healthcare utilization. METHODS: Data came from a retrospective, observational cohort study of 6066 adults with opioid use disorder who were incarcerated in New York City jails and released to the community during 2011-14. An outcome was community re-entry patterns identified by sequence analysis of 3-year post-release reincarceration, emergency department visits, and hospitalizations. An exposure was receipt of in-jail MOUD versus out-of-treatment (42 % vs. 58 %) for the last 3 days before discharge. The study accounted for differences in baseline demographic, clinical, behavioral, housing, and criminal legal characteristics between in-jail MOUD and out-of-treatment groups via propensity score matching. RESULTS: This study identified five re-entry patterns: stability (64 %), hospitalization (23 %), delayed reincarceration (7 %), immediate reincarceration (4 %), and continuous incarceration (2 %). After addressing confounding, 64 % and 57 % followed the stability pattern among MOUD and out-of-treatment groups who were released from jail in 2011, respectively. In 2012-14, the prevalence of following the stability pattern increased year-by-year while a consistently higher prevalence was observed among those with in-jail MOUD. CONCLUSIONS: Sequence analysis helped define post-release stability based on health and criminal legal system involvement. Receipt of in-jail MOUD was associated with a marker of successful community re-entry.

BACKGROUND: Non-fatal overdose is a leading predictor of subsequent fatal overdose. For individuals who are incarcerated, the risk of experiencing an overdose is highest when transitioning from a correctional setting to the community. We assessed if enrollment in jail-based medications for opioid use disorder (MOUD) is associated with lower risk of non-fatal opioid overdoses after jail release among individuals with opioid use disorder (OUD). METHODS: This was a retrospective, observational cohort study of adults with OUD who were incarcerated in New York City jails and received MOUD or did not receive any MOUD (out-of-treatment) within the last three days before release to the community in 2011-2017. The outcome was the first non-fatal opioid overdose emergency department (ED) visit within 1 year of jail release during 2011-2017. Covariates included demographic, clinical, incarceration-related, and other characteristics. We performed multivariable cause-specific Cox proportional hazards regression analysis to compare the risk of non-fatal opioid overdose ED visits within 1 year after jail release between groups. RESULTS: MOUD group included 8660 individuals with 17,119 incarcerations; out-of-treatment group included 10,163 individuals with 14,263 incarcerations. Controlling for covariates and accounting for competing risks, in-jail MOUD was associated with lower non-fatal opioid overdose risk within 14 days after jail release (adjusted HR=0.49, 95% confidence interval=0.33-0.74). We found no significant differences 15-28, 29-56, or 57-365 days post-release. CONCLUSION: MOUD group had lower risk of non-fatal opioid overdose immediately after jail release. Wider implementation of MOUD in US jails could potentially reduce post-release overdoses, ED utilization, and associated healthcare costs.

BACKGROUND: Offering medications for opioid use disorder (MOUD) in carceral settings significantly reduces overdose. However, it is unknown to what extent individuals in jails continue MOUD once they leave incarceration. We aimed to assess the relationship between in-jail MOUD and MOUD continuity in the month following release. METHODS: We conducted a retrospective cohort study of linked NYC jail-based electronic health records and community Medicaid OUD treatment claims for individuals with OUD discharged from jail between 2011 and 2017. We compared receipt of MOUD within 30 days of release, among those with and without MOUD at release from jail. We tested for effect modification based on MOUD receipt prior to incarceration and assessed factors associated with treatment discontinuation. RESULTS: Of 28,298 eligible incarcerations, 52.8 % received MOUD at release. 30 % of incarcerations with MOUD at release received community-based MOUD within 30 days, compared to 7 % of incarcerations without MOUD (Risk Ratio: 2.62 (2.44-2.82)). Most (69 %) with MOUD claims prior to incarceration who received in-jail MOUD continued treatment in the community, compared to 9 % of those without prior MOUD. Those who received methadone (vs. buprenorphine), were younger, Non-Hispanic Black and with no history of MOUD were less likely to continue MOUD following release. CONCLUSIONS: MOUD maintenance in jail is strongly associated with MOUD continuity upon release. Still, findings highlight a gap in treatment continuity upon-reentry, especially among those who initiate MOUD in jail. In the wake of worsening overdose deaths and troubling disparities, improving MOUD continuity among this population remains an urgent priority.

Gaze cues are important in communication. In social interactions gaze cues usually occur with spoken language, yet most previous research has used artificial paradigms without dialogue. The present study investigates the interaction between gaze and language using a real-world paradigm. Each participant followed instructions to build a series of abstract structures out of building blocks, while their eye movements were recorded. The instructor varied the specificity of the instructions (unambiguous or ambiguous) and the presence of gaze cues (present or absent) between participants. Fixations to the blocks were recorded and task performance was measured. The presence of gaze cues led to more accurate performance, more accurate visual selection of the target block and more fixations towards the instructor when ambiguous instructions were given, but not when unambiguous instructions were given. We conclude that people only utilize the gaze cues of others when the cues provide useful information.

Electromagnetic wave-based analogue computing has become an interesting computing paradigm demonstrating the potential for high-throughput, low power, and parallel operations. In this work, we propose a technique for the calculation of derivatives of temporal signals by exploiting transmission line techniques. We consider multiple interconnected waveguides (with some of them being closed-ended stubs) forming junctions. The transmission coefficient of the proposed structure is then tailored by controlling the length and number of stubs at the junction, such that the differentiation operation is applied directly onto the envelope of an incident signal sinusoidally modulated in the time domain. The physics behind the proposed structure is explained in detail and a full theoretical description of this operation is presented, demonstrating how this technique can be used to calculate higher order or even fractional temporal derivatives. We envision that these results may enable the development of further time domain wave-based analogue processors by exploiting waveguide junctions, opening new opportunities for wave-based single operators and systems.
RESUMO
Objective: The aim of this systematic review is to estimate: (i) the overall effect of blinding models on bias; (ii) the effect of each blinding model; and (iii) the effect of un-blinding on reviewer's accountability in biomedical research proposals. Methods: Systematic review of prospective or retrospective comparative studies that evaluated two or more peer review blinding models for biomedical research proposals/funding applications and reported outcomes related to peer review efficiency. Results: Three studies that met the inclusion criteria were included in this review and assessed using the QualSyst tool by two authors. Conclusion: Our systematic review is the first to assess peer review blinding models in the context of funding. While only three studies were included, this highlighted the dire need for further RCTs that generate validated evidence. We also discussed multiple aspects of peer review, such as peer review in manuscripts vs proposals and peer review in other fields.

BACKGROUND AND AIMS: Opioid overdose is a leading cause of death during the immediate time after release from jail or prison. Most jails in the United States do not provide methadone and buprenorphine treatment for opioid use disorder (MOUD), and research in estimating its impact in jail settings is limited. We aimed to test the hypothesis that in-jail MOUD is associated with lower overdose mortality risk post-release. DESIGN, SETTING AND PARTICIPANTS: Retrospective, observational cohort study of 15 797 adults with opioid use disorder who were released from New York City jails to the community in 2011-2017. They experienced 31 382 incarcerations and were followed up to 1 year. MEASUREMENTS: The primary outcomes were death caused by accidental drug poisoning and all-cause death. The exposure was receipt of MOUD (17 119 events) versus out-of-treatment (14 263 events) during the last 3 days before community re-entry. Covariates included demographic, clinical, behavioral, housing, health-care utilization and legal characteristics variables. We performed a multivariable, mixed-effect Cox regression analysis to test association between in-jail MOUD and deaths. FINDINGS: The majority were male (82%) and their average age was 42 years. Receiving MOUD was associated with misdemeanor charges, being female, injection drug use and homelessness. During 1 year post-release, 111 overdose deaths occurred and crude death rates were 0.49 and 0.83 per 100 person-years for in-jail MOUD and out-of-treatment groups, respectively. Accounting for confounding and random effects, in-jail MOUD was associated with lower overdose mortality risk [adjusted hazard ratio (aHR) = 0.20, 95% confidence interval (CI) = 0.08-0.46] and all-cause mortality risk (aHR = 0.22, 95% CI = 0.11-0.42) for the first month post-release. CONCLUSIONS: Methadone and buprenorphine treatment for opioid use disorder during incarceration was associated with an 80% reduction in overdose mortality risk for the first month post-release.

There are currently more adults age fifty-five or older incarcerated in the United States than ever before. Little is known about the epidemiology or health care needs of geriatric patients in jails, where the majority of the population is being held in pretrial detention. We performed a retrospective analysis of electronic health record data to characterize the demographics, health conditions, and health care use of people age fifty-five or older who were incarcerated in the New York City jail system between 2015 and 2019. People in this age group accounted for 4 percent of admissions to the jails in 2009, ten years before the study's end date; 7 percent of admissions in 2015, when the study began; and 8.5 percent of admissions by 2019. They were more likely to report being homeless; suffer from a serious mental illness designation; carry a higher burden of chronic, infectious, and serious medical illnesses; be hospitalized during their incarceration; and die in jail custody than their younger counterparts. All elements of the criminal justice system need to be attuned to the vulnerabilities of this group, implement targeted interventions to divert them from incarceration when possible, and minimize harms for those who end up incarcerated.

Journal impact factors, publication charges and assessment of quality and accuracy of scientific research are critical for researchers, managers, funders, policy makers, and society. Editors and publishers compete for impact factor rankings, to demonstrate how important their journals are, and researchers strive to publish in perceived top journals, despite high publication and access charges. This raises questions of how top journals are identified, whether assessments of impacts are accurate and whether high publication charges borne by the research community are justified, bearing in mind that they also collectively provide free peer-review to the publishers. Although traditional journals accelerated peer review and publication during the COVID-19 pandemic, preprint servers made a greater impact with over 30,000 open access articles becoming available and accelerating a trend already seen in other fields of research. We review and comment on the advantages and disadvantages of a range of assessment methods and the way in which they are used by researchers, managers, employers and publishers. We argue that new approaches to assessment are required to provide a realistic and comprehensive measure of the value of research and journals and we support open access publishing at a modest, affordable price to benefit research producers and consumers.
