RESUMEN

While global attention has been primarily focused on the occurrence and persistence of microplastics (MP) in urban lakes, relatively little attention has been paid to the problem of MP pollution in rural recreational lakes. This pioneering study aims to shed light on MP size, composition, abundance, spatial distribution, and contributing factors in a rural recreational lake, 'Nikli Lake' in Kishoreganj, Bangladesh. Using density separation, MPs were extracted from 30 water and 30 sediment samples taken from ten different locations in the lake. Subsequent characterization was carried out using a combination of techniques, including a stereomicroscope, Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FE-SEM). The results showed a significant prevalence of MPs in all samples, with an average amount of 109.667 ± 10.892 pieces/kg3 (dw) in the sediment and 98.167 ± 12.849 pieces/m3 in the water. Small MPs (<0.5 mm), fragments and transparent colored particles formed the majority, accounting for 80.2%, 64.5% and 55.3% in water and 78.9%, 66.4% and 64.3% in sediment, respectively. In line with global trends, polypropylene (PP) (53%) and polyethylene (PE) (43%) emerged as the predominant polymers within the MPs. MP contents in water and sediment showed positive correlations with outflow, while they correlated negatively with inflow and lake depth (p > 0.05). Local activities such as the discharge of domestic sewage, fishing waste and agricultural runoff significantly influence the distribution of polypropylene. Assessment of pollution factor, pollution risk index and pollution load index values at the sampling sites confirmed the presence of MPs, with values above 1. This study is a baseline database that provides a comprehensive understanding of MP pollution in the freshwater ecosystem of Bangladesh, particularly in a rural recreational lake. A crucial next step is to explore ecotoxicological mechanisms, legislative measures and future research challenges triggered by MP pollution.

RESUMEN

OBJECTIVES: the primary aim of this study was to examine the prevalence and risk factors of low bone mineral density in Bahrain. METHODS: this was a retrospective study, which targeted a cohort of 4822 Bahraini subjects (mean age 59.36 years: 93% females). Demographic data and results of lumbar and femur DEXA scan for the targeted sample, over the period 2016-2018, were retrieved from four hospitals. RESULTS: The prevalence of low BMD was 62.3% (46.4% had osteopenia and 15.9% had osteoporosis). The highest rate of osteopenia was detected at the age group younger than 44 years. However, with increasing age, the rate of osteopenia declined, whereas osteoporosis increased (P < 0.001). Females were found to be at higher risk of developing both osteopenia (45.8%) and osteoporosis (18.1%) compared to males (39% and 12.4%, respectively) (P < 0.001). Postmenopausal women exhibited higher rates of low BMD (42.4% osteopenia, 22.3% osteoporosis) compared to elderly men (30.9% osteopenia, 9% osteoporosis). CONCLUSIONS: We reported high prevalence of osteopenia and osteoporosis in Bahrain. Low BMD was more common in females, especially in postmenopausal women. Highest prevalence of osteopenia happened at young age. Therefore, we advocate screening at younger age than previously recommended.

RESUMEN

Introduction: Telehealth use in obstetrics has been demonstrated to improve efficiency, access to care, and pregnancy outcomes. Despite reported successful implementation of these programs, information regarding the program variations and its impact on health care costs and outcomes are scarce. Methods: This is a scoping review of pregnancy-related telehealth studies to understand the current landscape of pregnancy-related telehealth interventions as well as to subset those that are used in high-risk pregnancies. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework to guide this review. Results: A total of 70 articles were included in this scoping review. Of those, 53 (75.7%) studies included a pregnant population and 17 (24.3%) studies focused on a rural and/or urban population. Most studies (n = 56; 80%) included some form of synchronous interaction between provider and participant. Patient outcomes included maternal/infant health outcomes (n = 41; 44.1%), patient satisfaction (n = 9; 9.7%), and attendance/compliance (n = 5; 5.4%). Provider-level outcomes included knowledge change (n = 11; 11.8%) and self-efficacy (n = 3; 3.2%). Other outcomes included assessment of costs and patient/provider feasibility and acceptability of the intervention. Overall, there has been a growing trend in articles published on pregnancy-related telehealth studies since 2011, with 2018 having the most publications in a single year. Conclusion: This review suggests a steadily growing body of literature on pregnancy-related telehealth interventions; however, more research is needed to better understand outcomes of telehealth for pregnancy-related care, especially related to patient satisfaction, health disparities, and cost-benefit.

RESUMEN

PURPOSE: This study introduces the Order of Magnitude (OM), a cost-effective, indigenous, virtual reality-based visual field analyzer designed for detecting glaucomatous visual field loss. METHODS: The OM test employs a two-step supra-thresholding algorithm utilizing stimuli of 0.43°diameter (equivalent to Goldmann size III) at low and high thresholds. A comparative analysis was conducted against the Humphrey visual field (HVF) test, considered the gold standard in clinical practice. Participants, including those with glaucoma and normal individuals, underwent comprehensive eye examinations alongside the OM and HVF tests between April and October 2019. Diagnostic sensitivity and specificity of the OM test were assessed against clinical diagnoses made by specialists. RESULTS: We studied 157 eyes (74 glaucomatous, 83 control) of 152 participants. Results demonstrated a high level of reliability for both OM and HVF tests, with no significant difference observed (P = 0.19, Chi-square test). The sensitivity and specificity of the OM test were found to be 93% (95% CI 86-100%) and 83% (95% CI 72.4-93%), respectively, while the HVF test showed sensitivity and specificity of 98% (95% CI 93.9-100%) and 83% (95% CI 73.9-92.8%), respectively. CONCLUSION: These findings suggest that the OM test is non-inferior to the reference standard HVF test in identifying glaucomatous visual field loss.

RESUMEN

BACKGROUND: Most studies of immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) measure antibody or cellular responses in blood; however, the virus infects mucosal surfaces in the nose and conjunctivae and infectious virus is rarely if ever present in the blood. METHODS: We used luciferase immunoprecipitation assays to measure SARS-CoV-2 antibody levels in the plasma, nose, and saliva of infected persons and vaccine recipients. These assays measure antibody that can precipitate the SAR-CoV-2 spike and nucleocapsid proteins. RESULTS: Levels of plasma anti-spike antibody declined less rapidly than levels of anti-nucleocapsid antibody in infected persons. SARS-CoV-2 anti-spike antibody levels in the nose declined more rapidly than antibody levels in the blood after vaccination of infected persons. Vaccination of previously infected persons boosted anti-spike antibody in plasma more than in the nose or saliva. Nasal and saliva anti-spike antibody levels were significantly correlated with plasma antibody in infected persons who had not been vaccinated and after vaccination of uninfected persons. CONCLUSIONS: Persistently elevated SARS-CoV-2 antibody in plasma may not indicate persistence of antibody at mucosal sites such as the nose. The strong correlation of SARS-CoV-2 antibody in the nose and saliva with that in the blood suggests that mucosal antibodies are derived primarily from transudation from the blood rather than local production. While SARS-CoV-2 vaccine given peripherally boosted mucosal immune responses in infected persons, the increase in antibody titers was higher in plasma than at mucosal sites. Taken together, these observations indicate the need for development of mucosal vaccines to induce potent immune responses at sites where SARS-CoV-2 infection occurs. CLINICAL TRIALS REGISTRATION: NCT01306084.

RESUMEN

Vaccinations are effective in preventing infections; however, it is unknown if patients with chronic lymphocytic leukemia (CLL) who are treatment naïve (TN) or receiving Bruton tyrosine kinase inhibitors (BTKi's) respond to novel adjuvanted vaccines. Understanding the effect of BTKi's on humoral immunity is timely because BTKi's are widely used and vaccination against coronavirus disease 2019 is urgently needed. In 2 open-label, single-arm clinical trials, we measured the effect of BTKi's on de novo immune response against recombinant hepatitis B vaccine (HepB-CpG) and recall response against recombinant zoster vaccine (RZV) in CLL patients who were TN or on BTKi. The primary end point was serologic response to HepB-CpG (anti-hepatitis B surface antibodies ≥10 mIU/mL) and RZV (≥fourfold increase in anti-glycoprotein E). The response rate to HepB-CpG was lower in patients on BTKi (3.8%; 95% confidence interval [CI], 0.7-18.9) than patients who were TN (28.1%; 95% CI, 15.6-45.4; P = .017). In contrast, the response rate to RZV did not differ significantly between the BTKi (41.5%; 95% CI, 27.8-56.6) and TN cohorts (59.1%; 95% CI, 38.7-76.7; P = .2). BTKi's were associated with a decreased de novo immune response following HepB-CpG, whereas recall immune response following RZV was not significantly affected by BTKi therapy. These trials were registered at www.clinicaltrials.gov as #NCT03685708 (Hep-CpG) and #NCT03702231 (RZV).

RESUMEN

BACKGROUND: Hypertension management is complex in older adults. Recent advances in remote patient monitoring (RPM) have warranted evaluation of RPM use and patient outcomes. OBJECTIVE: To study associations of RPM use with mortality and healthcare utilization measures of hospitalizations, emergency department (ED) utilization, and outpatient visits. DESIGN: A retrospective cohort study. PATIENTS: Medicare beneficiaries aged ≥65 years with an outpatient hypertension diagnosis between July 2018 and September 2020. The first date of RPM use with a corresponding hypertension diagnosis was recorded (index date). RPM non-users were documented from those with an outpatient hypertension diagnosis; a random visit was selected as the index date. Six months prior continuous enrollment was required. MAIN MEASURES: Outcomes studied within 180 days of index date included (i) all-cause mortality, (ii) any hospitalization, (iii) cardiovascular-related hospitalization, (iv) non-cardiovascular-related hospitalization, (v) any ED, (vi) cardiovascular-related ED, (vii) non-cardiovascular-related ED, (viii) any outpatient, (ix) cardiovascular-related outpatient, and (x) non-cardiovascular-related outpatient. Patient demographics and clinical variables were collected from baseline and index date. Propensity score matching (1:4) and Cox regression were performed. Hazard ratios (HR) and 95% confidence intervals (CI) are reported. KEY RESULTS: The matched sample had 16,339 and 63,333 users and non-users, respectively. Cumulative incidences of mortality outcome were 2.9% (RPM) and 4.3% (non-RPM), with a HR (95% CI) of 0.66 (0.60-0.74). RPM users had lower hazards of any [0.78 (0.75-0.82)], cardiovascular-related [0.79 (0.73-0.87)], and non-cardiovascular-related [0.79 (0.75-0.83)] hospitalizations. No significant association was observed between RPM use and the three ED measures. RPM users had higher hazards of any [1.10 (1.08-1.11)] and cardiovascular-related outpatient visits [2.17 (2.13-2.19)], while a slightly lower hazard of non-cardiovascular-related outpatient visits [0.94 (0.93-0.96)]. CONCLUSIONS: RPM use was associated with substantial reductions in hazards of mortality and hospitalization outcomes with an increase in cardiovascular-related outpatient visits.

RESUMEN

Several studies have concluded that legalizing medical marijuana can reduce deaths from opioid overdoses. Drawing on micro data from the National Survey on Drug Use and Health, a survey uniquely suited to assessing patterns of substance use, we examine the relationship between recreational marijuana laws (RMLs) and the misuse of prescription opioids. Using a standard difference-in-differences (DD) regression model, we find that RML adoption reduces the likelihood of frequently misusing prescription opioids such as OxyContin, Percocet, and Vicodin. However, using a two-stage procedure designed to account for staggered treatment and dynamic effects, the DD estimate of relationship between RML adoption and the likelihood of frequently misusing prescription opioids becomes positive. Although event study estimates suggest that RML adoption leads to a decrease in the frequency of prescription opioid abuse, this effect appears to dissipate after only 2 or 3 years.

RESUMEN

OBJECTIVE: To evaluate the effect of maternal characteristics on the odds of severe maternal morbidity (SMM) through 42 days postpartum. STUDY DESIGN: We conducted a retrospective observational study of 77 172 births using birth certificate and insurance claims data from the Arkansas All Payers Claims Database, years 2013-2017, to identify racial disparities associated with SMM for births between April 1, 2014, and November 19, 2017. METHODS: Multiple logistic regression was used to examine the effect of sociodemographic factors and clinical comorbidities on the odds of SMM among non-Hispanic white ("white"), non-Hispanic Black ("Black"), and Hispanic women. RESULTS: The rate of SMM was 227.41 per 10 000 births, with Black women (330 per 10 000 births; 95% CI: 296.16-366.38), having a significantly higher rates than white women (197; 95% CI: 171.72-225.84) and Hispanic women (180; 95% CI: 155.86-207.54). After adjusting for maternal demographics, birth-related clinical variables, and comorbidities, SMM remained higher among Black women (aOR 1.37; 95% CI 1.11-1.70) relative to white women. CONCLUSIONS: Comorbidities, socioeconomic factors, and other factors did not fully explain the Black-white disparities in SMM. Persistent disparities in the rates of SMM throughout 42 days postpartum among Black women relative to white women points to the need for higher quality, more equitable care for women of color in the fist months postpartum.

RESUMEN

INTRODUCTION: Estimating Neonatal Abstinence Syndrome (NAS) and prenatal substance exposure rates in Medicaid can help target program efforts to improve access to services. METHODS: The data for this study was extracted from the 2016-2020 Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) Research Identifiable Files (RIF) and included infants born between January 1, 2016 and December 31, 2020 with a either a NAS diagnosis or prenatal substance exposure. RESULTS: Between 2016 and 2020, the estimated national rate of NAS experienced a 18% decline, while the estimated national rate of prenatal substance exposure experienced a 3.6% increase. At the state level in 2020, the NAS rate ranged from 3.2 per 1000 births (Hawaii) to 68.0 per 1000 births (West Virginia). Between 2016 and 2020, 28 states experienced a decline in NAS births and 20 states had an increase in NAS rates. In 2020, the lowest prenatal substance exposure rate was observed in New Jersey (9.9 per 1000 births) and the highest in West Virginia (88.1 per 1000 births). Between 2016 and 2020, 38 states experienced an increase in the rate of prenatal substance exposure and 10 states experienced a decline. DISCUSSION: Estimated rate of NAS has declined nationally, but rate of prenatal substance exposure has increased, with considerable state-level variation. The reported increase in prenatal substance exposure in the majority of US states (38) suggest that substances other than opioids are influencing this trend. Medicaid-led initiatives can be used to identify women with substance use and connect them to services.


What is already known about the topic? Neonatal Abstinence Syndrome (NAS) and prenatal substance exposure are significant risk factors for poor neurodevelopmental and mental health outcomes in early childhood. NAS birth rates have been increasing in the US since 2000 and the majority of NAS births are covered by Medicaid.What this article adds? This article estimates national and state-level prenatal substance exposure and NAS rates among Medicaid-covered infants born between 2016-2020 using data from the Transformed Medicaid Statistical Information System. This is the first study using post-2017 data to estimate national NAS rates. The findings can inform future federal and state policy efforts to improve access to screening, diagnosis and treatment among pregnant women with substance use disorder and infants with NAS.

RESUMEN

Having health insurance is associated with better access to healthcare and lower rates of comorbidity in the general population, but data are limited on insurance's impact on adults with congenital heart disease (ACHD). The Congenital Heart Survey To Recognize Outcomes, Needs and well-beinG (CH STRONG) was conducted among ACHD in three locations from 2016 to 2019. We performed multivariable logistic regression to determine the associations between health insurance and both access to healthcare and presence of comorbidities. We also compared health insurance and comorbidities among ACHD to similarly-aged individuals in the Behavioral Risk Factor Surveillance System (BRFSS) as a proxy for the general population. Of 1354 CH STRONG respondents, the majority were ≤ 30 years old (83.5%), and 8.8% were uninsured versus 17.7% in the BRFSS (p < 0.01). Compared to insured ACHD, uninsured were less likely to report regular medical care (adjusted odds ratio [aOR] 0.2, 95% confidence interval [CI] 0.1-0.3) and visited an emergency room more often (aOR 1.6, CI 1.0-2.3). Among all ACHD reporting disability, uninsured individuals less frequently received benefits (aOR 0.1, CI 0.0-0.3). Depression was common among uninsured ACHD (22.5%), but insured ACHD had lower rates of depression than insured in the BRFSS (13.3% vs. 22.5%, p < 0.01). In conclusion, rates of insurance were higher among ACHD compared to the general population. Nonetheless, uninsured ACHD inconsistently accessed healthcare and benefits. Further studies are needed to determine if insurance ameliorates the risk of morbidity as ACHD age.

RESUMEN

Introduction: The COVID-19 pandemic brought about renewed interest and investment in telehealth, while also highlighting persistent health disparities in the Southern states. Little is known about the characteristics of those utilizing telehealth services in Arkansas, a rural Southern state. We sought to compare the characteristics of telehealth utilizers and nonutilizers among Medicare beneficiaries in Arkansas before the COVID-19 public health emergency to provide a baseline for future research investigating disparities in telehealth utilization. Methods: We used Arkansas Medicare beneficiary data (2018-2019) to model telehealth use. We included interactions to assess how the association between the number of chronic conditions and telehealth was moderated by race/ethnicity and rurality, adjusted for covariates. Results: Overall telehealth utilization in 2019 was low (n = 4,463; 1.1%). The adjusted odds of utilizing telehealth was higher for non-Hispanic Black/African Americans (vs. white, adjusted odds ratio [aOR] = 1.34, 95% confidence interval [CI] = 1.17-1.52), rural beneficiaries (aOR = 1.99, 95% CI = 1.79-2.21), and those with more chronic conditions (aOR = 1.23, 95% CI = 1.21-1.25). Race/ethnicity and rurality were significant moderators, such that the association between the number of chronic conditions and telehealth was strongest among white and among rural beneficiaries. Discussion: Among the 2019 Arkansas Medicare beneficiaries, having more chronic conditions was most strongly associated with telehealth use among white and rural individuals, while the effect was not as pronounced for Black/African American and urban individuals. Our findings suggest that advances in telehealth are not benefiting all Americans equally, with aging minoritized communities continuing to engage with more strained and underresourced health systems. Future research should investigate how upstream factors such as structural racism perpetuate poor health outcomes.

RESUMEN

Introduction: Limited information exists on the landscape of studies and policies for remote patient monitoring (RPM) in the United States. Methods: We conducted a scoping review to assess (1) for which adult patient populations and health care needs is RPM being used and (2) the landscape of national- and state-level reimbursement policies for RPM. This study was guided by the Arksey and O'Malley methodological framework for scoping reviews and the Joanna Briggs Institute Manual for Evidence Synthesis. Results: A total of 399 articles were included in our final sample: 268 study articles and 131 articles of gray literature (e.g., websites, legislative bills). RPM-related articles rose drastically from 2015 to 2021, and the vast majority of articles were peer-reviewed journal articles. Of the study articles, prospective cohort studies were the most common study method, with m-health/smart watches being the most common RPM modality. RPM was found to be most commonly tested within patients with cardiovascular diseases, and the most common outcomes measured were usability and feasibility. Gray literature found 36 U.S. state Medicaid programs had reimbursement policies for RPM in 2021; however, 28 of those had at least one restriction on reimbursement (e.g., limited to specific providers). Conclusions: Despite the rapid growth in the literature on RPM and the adoption of reimbursement policies, retrospective, population-level studies, large randomized controlled trials, studies with a focus on additional favorable outcomes (e.g., quality of life), and studies evaluating trends in RPM reimbursement policies are lacking in the current literature.

RESUMEN

Studies in recent years have shown that aquatic pollution by microplastics (MPs) can be considered to pose additional stress to amphibian populations. However, our knowledge of how MPs affect amphibians is very rudimentary, and even more limited is our understanding of their effects in combination with other emerging pollutants. Thus, we aimed to evaluate the possible toxicity of polyethylene MPs (PE-MPs) (alone or in combination with a mix of pollutants) on the health of Physalaemus cuvieri tadpoles. After 30 days of exposure, multiple biomarkers were measured, including morphological, biometric, and developmental indices, behavioral parameters, mutagenicity, cytotoxicity, antioxidant and cholinesterase responses, as well as the uptake and accumulation of PE-MPs in animals. Based on the results, there was no significant change in any of the parameters measured in tadpoles exposed to treatments, but induced stress was observed in tadpoles exposed to PE-MPs combined with the mixture of pollutants, reflecting significant changes in physiological and biochemical responses. Through principal component analysis (PCA) and integrated biomarker response (IBR) assessment, effects induced by pollutants in each test group were distinguished, confirming that the exposure of P. cuvieri tadpoles to the PE-MPs in combination with a mix of emerging pollutants induces an enhanced stress response, although the uptake and accumulation of PE-MPs in these animals was reduced. Thus, our study provides new insight into the danger to amphibians of MPs coexisting with other pollutants in aquatic environments.

RESUMEN

Varicella-zoster virus (VZV) maintains lifelong latency in neurons following initial infection and can subsequently be reactivated to result in herpes zoster or severe neurological manifestations such as encephalitis. Mechanisms of VZV neuropathogenesis have been challenging to study due to the strict human tropism of the virus. Although neuronal entry mediators of other herpesviruses, including herpes simplex virus, have been identified, little is known regarding how VZV enters neurons. Here, we utilize a human stem cell-based neuronal model to characterize cellular factors that mediate entry. Through transcriptional profiling of infected cells, we identify the cell adhesion molecule nectin-1 as a candidate mediator of VZV entry. Nectin-1 is highly expressed in the cell bodies and axons of neurons. Either knockdown of endogenous nectin-1 or incubation with soluble forms of nectin-1 produced in mammalian cells results in a marked decrease in infectivity of neurons. Notably, while addition of soluble nectin-1 during viral infection inhibits infectivity, addition after infection has no effect on infectivity. Ectopic expression of human nectin-1 in a cell line resistant to productive VZV infection confers susceptibility to infection. In summary, we have identified nectin-1 as a neuronal entry mediator of VZV. IMPORTANCE Varicella-zoster virus (VZV) causes chickenpox, gains access to neurons during primary infection where it resides lifelong, and can later be reactivated. Reactivation is associated with shingles and postherpetic neuralgia, as well as with severe neurologic complications, including vasculitis and encephalitis. Although the varicella vaccine substantially decreases morbidity and mortality associated with primary infection, the vaccine cannot prevent the development of neuronal latency, and vaccinated populations are still at risk for reactivation. Furthermore, immunocompromised individuals are at higher risk for VZV reactivation and associated complications. Little is known regarding how VZV enters neurons. Here, we identify nectin-1 as an entry mediator of VZV in human neurons. Identification of nectin-1 as a neuronal VZV entry mediator could lead to improved treatments and preventative measures to reduce VZV related morbidity and mortality.

Opioid use disorder (OUD) is a significant public health problem in the United States, which affects children as well as adults. During 2010-2017, maternal opioid-related diagnoses increased approximately 130%, from 3.5 to 8.2 per 1,000 hospital deliveries, and neonatal abstinence syndrome (NAS) increased 83%, from 4.0 to 7.3 per 1,000 hospital deliveries (1). NAS, a withdrawal syndrome, can occur among infants following in utero exposure to opioids and other psychotropic substances (2). In 2018, a study of six states with mandated NAS case reporting for public health surveillance (2013-2017) found that mandated reporting helped quantify NAS incidence and guide programs and services (3). To review surveillance features and programmatic development in the same six states, a questionnaire and interview with state health department officials on postimplementation efforts were developed and implemented in 2021. All states reported ongoing challenges with initial case reporting, limited capacity to track social and developmental outcomes, and no requirement for long-term follow-up in state-mandated case reporting; only one state instituted health-related outcomes monitoring. The primary surveillance barrier beyond initial case reporting was lack of infrastructure. To serve identified needs of opioid- or other substance-exposed mother-infant dyads, state health departments reported programmatic successes expanding education and access to maternal medication for opioid use disorder (MOUD), community and provider education or support services, and partnerships with perinatal quality collaboratives. Development of additional infrastructure is needed for states aiming to advance NAS surveillance beyond initial case reporting.

RESUMEN

Design: A prospective study was conducted. Setting. This study took place at King Fahd Hospital of the University, Imam AbdulRahman Bin Faisal University, Dammam, Saudi Arabia. Primary and Secondary Outcomes. The study aimed to evaluate changes in BMD and prevention of fragility fractures. Materials and Methods: We followed up 439 patients who were prescribed teriparatide at the King Fahd Hospital of the University, AlKhobar, and 415 (94.5%) patients completed a 24-month teriparatide course. The data gathered before starting medication were age, sex, previous therapy, history of fractures, and other diseases like diabetes mellitus, hypertension, and cardiac disease. At the time of the final assessment after 24 months, a history of fractures if any during the treatment was collected and a DXA scan was done. Results: A total of 415 patients were followed up for 2 years. Three hundred and sixty-five patients (87.9%) were females, and the rest were males. The average age was 68.21 ± 17.6 years. Two hundred and forty-eight patients (59.8%) were treatment naïve, and 167 (40.2%) were on treatment for osteoporosis. Twenty patients (4.8%) sustained fracture on treatment. The pretreatment DXA showed that the mean hip T-score was -3.1 ± 0.79, and after completion of the treatment, it was -1.5 ± 0.62 (P < 0.001), while the T-score of the lumbar spine was 4.4 ± 0.86 versus -3.2 ± 0.87 (P < 0.001). Seventeen (4.09%) had fractures while on teriparatide treatment. The mean significant gain (MSG) for BMD for the hip was 0.095 g/cm2, and for the lumbar spine, it was was 0.109 g/cm2 with P < 0.001 at 95% CI. Conclusions: Our study shows that 94.5% completed the treatment duration, and there was an increase in the BMD. The decrease in T-scores of the lumbar spine and hip was significant so was the reduction in the number of fractures.

RESUMEN

Background: The federal government has made several efforts to increase access to buprenorphine for the treatment of opioid use disorder (OUD). However, patients continue to face challenges in access to treatment for OUD. Objectives: This study seeks to examine the trends in the prevalence of buprenorphine-waivered practitioners who opt to be publicly listed on the Buprenorphine Treatment Practitioner Locator tool maintained by the Substance Abuse and Mental Health Services Administration (SAMHSA) and how this varies between Medicaid expansion and non-expansion states. Methods: Administrative records of all the DATA-waivered providers collected by SAMHSA were utilized to identify the trends in the number of waivered practitioners by their public listing status from 2002-2017. We further examine how that trend varied between Medicaid expansion and non-expansion states. Results: The total number of waivered providers increased steadily from 300 in 2002 to 41,960 in 2017. In 2015, the number of waivered providers began to increase rapidly, with the number in Medicaid expansion states increasing faster than in non-expansion states from 2014-2017 (136% vs. 59%). Even though a greater proportion of waivered providers listed their names publicly in non-expansion states than in expansion states from 2014-2017, the rate of public listing of names increased more rapidly in Medicaid expansion states than in non-expansion states (170% vs. 85%) during the same period. Conclusions: This finding suggests that even though there has been an increase in waivered providers to prescribe buprenorphine in Medicaid expansion and non-expansion states, barriers to access treatment still persist. Policy initiatives that seek to expand access to substance-use treatment are warranted.

RESUMEN

The spreading of sewage sludge from wastewater treatment plants and various industries arouses the growing interest due to the contamination by trace elements. Sludges were collected from one sewage treatment plant and two industries in Dhaka City, Bangladesh to assess physicochemical parameters and total and fraction content of trace elements like Cr, Ni, Cu, As, Cd, Pb, Fe, Mn and Zn in sludges. We evaluated the bioavailability of theses metals by determining their speciation by sequential extraction, each metal being distributed among five fractions: exchangeable fraction, bound to carbonate fraction, Fe-Mn oxide bound fraction, organic matter bound fraction and residual fractions. We found that all the analyzed sludges had satisfactory properties from an agronomic quality point of view. The average concentration (mg/kg) of trace metals in sludge samples were in the following decreasing order Fe (12807) > Cr (200) > Mn (158) > Zn (132) > Cu (68.2) > Ni (42.5) > Pb (36.4) > As (35.1) > Cd (3.7). The results of the sequential extraction showed that Cr, Ni, Cu, Fe and Mn were largely associated with the residual fraction where As, Cd and Pb was dominantly associated with the exchangeable and carbonate bound fractions and Zn showed a considerable proportion in carbonate bound fraction. These results showed that regulations must take into account the bioavailability with regard to the characteristics of the agricultural soils on which sludge will be spread.

RESUMEN

Blunt abdominal trauma (BAT) refers to injuries without wounds entering the peritoneal cavity due to road traffic accidents (RTA) and falls, as a result of collision or counter collision. The objective of the present study was to determine the frequency of patients with visceral injuries in blunt abdominal trauma. This study was carried out in the Department of Surgery, including ward-3 of Jinnah Post Graduate Medical Centre, Karachi, from November 2017 till November 2020. The study design was descriptive case series. During the study period, the data of 112 patients was collected, which comprised of 102 males and 10 females. All the patients between 12 to 65 years of age (mean age:31.84±13.14 years) presenting to the emergency with < 24 hours of abdominal trauma, were included in the study. Organs involved during blunt abdominal trauma were observed and frequency was recorded. Liver injuries were found in 48(42.28%) patients, intestinal injuries in 40(35.7%), splenic injuries in 32(28.5%), kidney injuries in 24(21.4%), pancreatic injuries in 8(7.1%) and stomach injuries in 4(3.5%) patients. Grade 4 liver injury was found in 80(71%) patients, Grade 2 and 3 splenic injuries in 56(50%) patients whereas 47(42%) patients had grade 1 kidney injury. Liver was found to be the most frequent organ involved, followed by intestine and spleen.
