RESUMEN

OBJECTIVE: The study aims to explore the perceived outcomes of Medical Teaching Institution (MTI) reforms on autonomy and overall performance within tertiary healthcare institutions in Khyber Pakhtunkhwa (KP) province, Pakistan. METHODOLOGY: A cross-sectional study was carried out from September 2023 to March 2024, involving interviews with frontline staff, administrative personnel, and senior management within MTI-affiliated institutions. The methodology employed, using both qualitative and quantitative data analysis techniques. RESULTS: The study showed that institutional staff members' knowledge and understanding of the MTI changes differed. Some observed very minor adjustments, while others saw advances in hospital operations and service delivery. Administrative complexity, political meddling, and resource allocation problems were noted as challenges. Positive results were also observed, though, and they included improved infrastructure, possibilities for staff training, and decision-making procedures. CONCLUSION: Despite significant improved, there are still challenges, such as inconsistent staff comprehension, mixed impacts on service delivery, resource allocation issues, and political meddling. Addressing these issues necessitates improved communication, continuous evaluation, and coordinated efforts to improve administrative systems and obtain consistent funding.

RESUMEN

BACKGROUND: One in three adolescents with type 1 diabetes mellitus (T1DM) experiences diabetes distress, which predicts poor self-management and glycemic control. Mindfulness-based interventions such as meditation have been associated with reduced psychological distress and health outcomes in different populations. This study explores the psychosocial barriers and facilitators of diabetes self-management and beliefs about meditation practices. METHODS: Eight adolescents aged 15-19 who had been diagnosed with T1DM for more than a year were invited to participate in a 40-60-minute semi-structured one-on-one interview. Their parents were also invited to participate in the study. Three of the eight parents invited were able to participate in the study. Participants were asked about perceived psychosocial barriers and facilitators of diabetes self-management and their beliefs about meditation as a tool for addressing some of the psychosocial barriers to self-management. Data were analyzed using NVivo 10 (QSR International, Melbourne, Australia). Conventional content analysis was conducted based on an inductive coding approach. RESULTS: Adolescents with T1DM had similar psychosocial challenges with managing T1DM, including high levels of diabetes distress and forgetfulness due to competing demands on their time. They also noted similar facilitators to effective self-management, such as the presence of family and peer support. Acceptance of T1DM diagnosis and personal commitment to self-management were also indicated as common facilitators of self-management. Adolescents with T1DM and parents of adolescents with T1DM believe that meditation can play a positive role in T1DM self-management by reducing diabetes distress and improving mental health and overall well-being. CONCLUSION: Results suggest that adolescents with T1DM and parents of adolescents with T1DM believe peer and family support is crucial to diabetes self-management. They also noted that diabetes distress and forgetfulness are primary barriers to self-management. Participants also see a potential for meditation to help manage general stress and diabetes distress, thereby aiding self-management. Further research is needed to explore meditation-based interventions to reduce diabetes distress in adolescents diagnosed with T1DM. The findings from this study can inform the development and implementation of meditation-based interventions that integrate family and peer support to reduce diabetes distress and enhance self-management in adolescents with T1DM.

RESUMEN

PURPOSE/OBJECTIVE: This study aimed to determine the feasibility of using commercially available heart rate variability (HRV) biofeedback training to improve physiological and self-reported stress and anxiety among adults with tetraplegia. HRV biofeedback teaches individuals to effectively modify their HRV levels in synchronization with their respiration rate and amplitude. RESEARCH METHOD/DESIGN: Thirty participants with tetraplegia were enrolled and allocated into one of two study arms: biofeedback or control. The study was conducted remotely from June 2022 through February 2023. Participants in the biofeedback arm received eight HRV training sessions with physiological monitoring, while participants in the control arm received physiological monitoring only. Outcome measures included feasibility, percentage of time spent in the low-frequency range, the Depression Anxiety Stress Scale-21, the Subjective Units of Distress Scale, and the State-Trait Anxiety Inventory-Y Form. RESULTS: Feasibility was demonstrated with 100% completion of the protocol and no participant withdrawals due to adverse events. The biofeedback arm showed a greater percentage of time spent in the low-frequency range and reported greater improvement in anxiety from baseline to Session 8 on the Subjective Units of Distress Scale compared to the control arm. However, no differences were found between study arms on the Depression Anxiety Stress Scale-21 and State-Trait Anxiety Inventory-Y Form. CONCLUSIONS/IMPLICATIONS: This study demonstrated that a remotely delivered, self-administered HRV biofeedback intervention could feasibly be delivered to individuals with tetraplegia who report moderate-to-high levels of anxiety. Trends in the reduction of physiological and self-reported anxiety were observed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMEN

Decades of conflict, political instability, and limited infrastructure left Somalia facing significant challenges to offer consistent and equitable health services, especially for child vaccination. Recent data reveals alarming vaccination gaps, with 60% of children receiving no vaccinations, and only 11% completing required vaccines. Despite global support, an estimated 1.15 million children remain unvaccinated, half of them reside in inaccessible areas controlled by non-state armed actors. In this context, the Far-Reaching Integrated Delivery (FARID) project was initiated since October 2022 across 10 districts of Galmudug and Hirshabelle state in Somalia. Employing the 'Health Camp' model, FARID addresses social, structural, and gender barriers, adapting to ever-changing context of inaccessible regions by providing mobile health facilities and outreach health and nutrition services, including child vaccination. This approach effectively reached previously unreached population in Somalia's most difficult-to-reach areas. Implemented in phases, the project immunized 51,168 children (0-23 months) who had not received any prior vaccinations (23,753 boys and 27,415 girls), screened and treated 14,158 malnourished children (0-59 months) and vaccinated 11,672 pregnant women during March-December 2023. The project's success hinges on intensive community engagement, local partnerships, innovation in mapping and data management, and delivery of integrated services tailored to population needs. The project underscores the critical role of local community-based organizations and clan elders in reaching inaccessible populations through humanitarian negotiation amidst security challenges. The project has achieved significant milestones aligned with national health strategic plans, including progress towards universal health coverage and improved immunization access in Somalia's most challenging regions.


Main findings To improve immunization coverage in areas with access constraints, programs must be integrated, utilize innovation in data systems and mapping and have deep knowledge of humanitarian access negotiation techniques and principles.Added knowledge Rights-based approaches including participation, empowerment and accountability are key for a successful immunization program for equitable access.Global health impact for policy and action The strengthening of human rights for health through inclusion of populations living under non-state actors' control in national health policies and legal frameworks is key for equitable access to vaccination to prevent and stop mortalities and morbidities caused by outbreaks and pandemics.

RESUMEN

Purpose: To examine factors of influence in diabetes management and their association with self-reported health outcomes in patients with type 2 diabetes treated at Federally Qualified Health Centers (FQHCs). Methods: This cross-sectional study examined data from the 2014 Health Center Patient Survey (HCPS). Predictor variables were categorized across three levels of the National Institute on Minority Health and Health Disparities research framework. Outcome variables retrieved from HCPS included self-reports of blood glucose levels, and diabetes-related emergency department (ED)/hospital visits during past year. Results: A total of 936 patients with diabetes were included. Most (65%) participants received a diabetes self-management plan. During the previous year, 72% received > = 2 A1C checks, 52% reported high blood glucose levels, and 12% visited an ED/hospital. Multivariable results showed that insulin use and receiving a self-management plan were associated with high blood glucose levels and ED/hospital visits. Community factors of being unable to get medications and receiving a specialist foot exam were respectively associated with high blood glucose levels and ED/hospital visits. Conclusion: Different factors were associated with health outcomes in patients with diabetes treated at FQHCs. Identifying these factors can help with targeted screening and follow-up and assessing potential interventions to improve health outcomes.

RESUMEN

Neuroblastoma is an embryonic cancer that contributes disproportionately to death in young children. Sequencing data have uncovered few recurrently mutated genes in this cancer, although epigenetic pathways have been implicated in disease pathogenesis. We used an expression-based computational screen that examined the impact of deubiquitinating enzymes on patient survival to identify potential new targets. We identified the histone H2B deubiquitinating enzyme USP44 as the enzyme with the greatest impact on survival in patients with neuroblastoma. High levels of USP44 significantly correlate with metastatic disease, unfavorable histology, advanced patient age, and MYCN amplification. The subset of patients with tumors expressing high levels of USP44 had significantly worse survival, including those with tumors lacking MYCN amplification. We showed experimentally that USP44 regulates neuroblastoma cell proliferation, migration, invasion, and neuronal development. Depletion of the histone H2B ubiquitin ligase subunit RNF20 resulted in similar findings, strongly implicating this histone mark as the target of USP44 activity in this disease. Integration of transcriptome and epigenome in analyses demonstrates a distinct set of genes that are regulated by USP44, including those in Hallmark MYC target genes in both murine embryonic fibroblasts and the SH-SY5Y neuroblastoma cell line. We conclude that USP44 is a novel epigenetic regulator that promotes aggressive features and may be a novel target in neuroblastoma. Implications: This study identifies a new genetic marker of aggressive neuroblastoma and identifies the mechanisms by which its overactivity contributes to the pathophysiology of this disease.

RESUMEN

INTRODUCTION: The Veterans Health Administration (VHA) established the Airborne Hazards and Open Burn Pit Registry (AHOBPR) in 2014 to address exposure concerns for veterans who have served in military operations in Southwest Asia and Afghanistan. By 2021, over 236,086 veterans completed the online questionnaire and 60% requested an AHOBPR examination. Of those requesting an exam, only 12% had an exam recorded in their medical record. This article summarizes barriers and facilitators to delivering AHOBPR exams and shares lessons learned from facilities who have successfully implemented burn pit exams for veterans. MATERIALS AND METHODS: We (I.C.C and J.H.) constructed a key performance measure of AHOBPR examination (the ratio of examinations performed in facility over examinations assigned to a facility) to identify top performing facilities and then used stratified purposeful sampling among high-performing sites to recruit a diverse set of facilities for participation. We (P.V.C. and A.A.) recruited and interviewed key personnel at these facilities about their process of administering burn pit exams. Rapid qualitative methods were used to analyze interviews. RESULTS: The ratio of exams performed to exams assigned ranged from 0.00 to 14.50 for the 129 facilities with available information. Twelve interviews were conducted with a total of 19 participants from 10 different facilities. We identified 3 barriers: Unclear responsibility, limited incentives and competing duties for personnel involved, and constrained resources. Facilitators included the presence of an internal facilitator, additional staff support, and coordination across a facility's departments to provide care. CONCLUSIONS: Gaps across many VHA facilities to provide AHOBPR exams may be understood as stemming from organizational issues related to clear delegation of responsibility and staffing issues. VHA facilities that wish to increase AHOBPR exams for veterans may need additional administrative and medical staff.

RESUMEN

INTRODUCTION: The impact of direct antiviral drugs (DAAs) on extrahepatic manifestations in chronic hepatitis C (CHC) has been poorly studied. AIM: To assess the prevalence of subclinical atherosclerosis in patients with CHC and the impact of DAAs on atherosclerotic lesions. Methods A 5-year prospective evaluative study, including patients followed for CHC at hepato-gastroenterology department. The subclinical atherosclerosis was assessed by ultrasound measurement of carotid intima-media thickness (IMTc) and the highest IMTc measurements from the left and right side defined the IMTc maximum (IMTc max). IMTc>75th percentile (IMTc75) define subclinical atherosclerosis with high cardiovascular risk. Patients were evaluated before (T0) and one year after DAAs therapy achievement (T1). RESULTS: At time T0, forty patients (median age: 55 y.; sex ratio M / F = 0.48), were included. Average value of IMTc max was 0.68 ± 0.16 mm. Subclinical atherosclerosis was noted in 82.5 %. At time T1, 28 patients were evaluated, all of whom completed sustained virological response (SVR). Compared to time T0, there was a significant increase in cholesterol (p = 0.001) and triglyceride (p = 0.009) levels. IMTc max was significantly higher at time T1 compared to T0 (0.75 Vs 0.67 mm, p = 0.04). Prevalence of IMTc75 was 82.1% at time T0 and 75% at time T1 (p=0.5). CONCLUSIONS: SVR, in CHC patients treated with DAA, was associated with worsening of carotid atherosclerotic lesions.

RESUMEN

INTRODUCTION: Individuals with skin of colour (SoC) have delayed diagnosis and poorer outcomes when presenting with some dermatologic conditions when compared to individuals with light skin (LS). The objective of this study was to determine if diagnostic performance bias can be mitigated by a skin-tone balanced dermatology curriculum. METHODOLOGY: A prospective randomised intervention study occurred over 2 weeks in 2020 at a Canadian medical school. A convenience sample of all first-year medical students (n = 167) was chosen. In week 1, all participants had access to dermatology podcasts and were randomly allocated to receive non-analytic training (NAT; online patient 'cards') on either SoC cases or LS cases. In week 2, all participants received combined training (CT; NAT and analytic training through workshops on how to apply dermatology diagnostic rules for all skin tones). Participating students completed two formative assessments after weeks 1 and 2. RESULTS: Ninety-two students participated in the study. After week 1, both groups had a lower diagnostic performance on SoC (p = 0.0002 and p = 0.002 for students who trained on LS 'cards' and SoC 'cards', respectively). There was a significant decrease in mean skin tone difference in both groups after week 2 (initial training on SoC: 5.8% (SD 12.2) pre, -1.4% (14.7) post, p = 0.007; initial training on LS: 7.8% (15.4) pre, -4.0% (11.8%) post, p = 0.0001). Five students participated in a post-study survey in 2023, and all found the curriculum enhanced their diagnostic skills in SoC. CONCLUSIONS: SoC performance biases of medical students disappeared after CT in a skin tone-balanced dermatology curriculum.

RESUMEN

Objectives: Low cognitive performance is a major concern among fishermen's children in Malaysia. Thus, this study was aimed at assessing dietary intake, nutritional status, physical activity, and socio-economic status, and their associations with cognitive performance among fishermen's children in Terengganu, Malaysia. We also investigated the risk associated with low cognitive performance. Methods: This cross-sectional study included 94 children 7-11 years of age in Terengganu. Dietary adequacy was assessed with two 24-h dietary recall surveys. Anthropometric measurements were assessed by calculation of the body mass index (BMI)-for-age Z-score and height-for-age Z-score. In addition, median urinary iodine tests were conducted to determine iodine concentrations. Physical activity was measured with the Physical Activity Questionnaire for Children (PAQ-C). Raven's coloured progressive matrices were used to determine cognitive performance. Binominal logistic regressions were performed on factors associated with cognitive performance, to identify the risk factors with the strongest association with cognitive performance. Results: The children of fishermen had adequate intake of all necessary nutrients except for fat, dietary fibre, thiamine, folate, vitamin C, vitamin E, calcium, zinc, and potassium. Most of the children had normal BMI-for-age [median = -0.86 (2.11)] and height-for-age (mean = -1.01 ± 1.03). However, more than half had iodine deficiency [median = 83.9 (102)]. In addition, 16% had low physical activity levels, and their cognitive performance was classified with a low average score [median = 80.0 (21.0)]. The mother's education level (p = 0.037), children's BMI-for-age (p = 0.012), protein (p = 0.020), and niacin (p = 0.032), exhibited significant relationships with cognitive performance (p < 0.05). Of these variables, BMI-for-age (OR = 0.290, p = 0.036) and fourth quartile protein intake (≥52.69 g) (OR = 7.565, p = 0.015) were significant risk factors for low cognitive performance among fishermen's children in Terengganu. Conclusion: A balanced diet and healthy lifestyle are crucial for children's cognitive development. Thus, interventions emphasising the promotion of healthy lifestyles, particularly focusing on BMI-for-age and protein intake, are advised.

RESUMEN

Since the Global Polio Eradication Initiative (GPEI) began in 1988, the number of wild poliovirus (WPV) cases has declined by >99.99%. Five of the six World Health Organization (WHO) regions have been certified free of indigenous WPV, and WPV serotypes 2 and 3 have been declared eradicated globally (1). WPV type 1 (WPV1) remains endemic only in Afghanistan and Pakistan (2,3). Before the outbreak described in this report, WPV1 had not been detected in southeastern Africa since the 1990s, and on August 25, 2020, the WHO African Region was certified free of indigenous WPV (4). On February 16, 2022, WPV1 infection was confirmed in one child living in Malawi, with onset of paralysis on November 19, 2021. Genomic sequence analysis of the isolated poliovirus indicated that it originated in Pakistan (5). Cases were subsequently identified in Mozambique. This report summarizes progress in the outbreak response since the initial report (5). During November 2021-December 2022, nine children and adolescents with paralytic polio caused by WPV1 were identified in southeastern Africa: one in Malawi and eight in Mozambique. Malawi, Mozambique, and three neighboring countries at high risk for WPV1 importation (Tanzania, Zambia, and Zimbabwe) responded by increasing surveillance and organizing up to six rounds of national and subnational polio supplementary immunization activities (SIAs).* Although no cases of paralytic WPV1 infection have been reported in Malawi since November 2021 or in Mozambique since August 2022, undetected transmission might be ongoing because of poliovirus surveillance gaps and testing delays. Efforts to further enhance poliovirus surveillance sensitivity, improve SIA quality, and strengthen routine immunization are needed to ensure that WPV1 transmission has been interrupted within 12 months of the first case, thereby preserving the WHO African Region's WPV-free status.

RESUMEN

OBJECTIVE: Many clinical and preclinical studies have implicated an association between atrial fibrillation (AF) and its progression to imbalances in the gut microbiome composition. The gut microbiome is a diverse and complex ecosystem containing billions of microorganisms that produce biologically active metabolites influencing the host disease development. METHODS: For this review, a literature search was conducted using digital databases to systematically identify the studies reporting the association of gut microbiota with AF progression. RESULTS: In a total of 14 studies, 2479 patients were recruited for the final analysis. More than half (n = 8) of the studies reported alterations in alpha diversity in atrial fibrillation. As for the beta diversity, 10 studies showed significant alterations. Almost all studies that assessed gut microbiota alterations reported major taxa associated with atrial fibrillation. Most studies focused on short-chain fatty acids (SCFAs), whereas three studies evaluated TMAO levels in the blood, which is the breakdown product of dietary l-carnitine, choline, and lecithin. Moreover, an independent cohort study assessed the relationship between phenylacetylglutamine (PAGIn) and AF. CONCLUSION: Intestinal dysbiosis is a modifiable risk factor that might provide newer treatment strategies for AF prevention. Well-designed research and prospective randomized interventional studies are required to target the gut dysbiotic mechanisms and determine the gut dysbiotic-AF relationship.

RESUMEN

BACKGROUND: Accurate mortality data associated with infectious diseases such as coronavirus disease 2019 (COVID-19) are often unavailable in countries with fragile health systems such as Somalia. We compared officially reported COVID-19 deaths in Somalia with COVID-19 deaths estimated using verbal autopsy. METHODS: We interviewed relatives of deceased persons to collect information on symptoms, cause, and place of death. We compared these data with officially reported data and estimated the positive and negative predictive values of verbal autopsy. RESULTS: We identified 530 deaths during March-October 2020. We classified 176 (33.2%) as probable COVID-19 deaths. Most deaths (78.5%; 416/530) occurred at home and 144 (34.6%) of these were attributed to COVID-19. The positive predictive value of verbal autopsy was lower for home deaths (22.3%; 95% CI: 15.7-30.1%) than for hospital deaths (32.3%; 95% CI: 16.7-51.4%). The negative predictive value was higher: 97.8% (95% CI: 95.0-99.3%) for home deaths and 98.4% (95% CI: 91.5-100%) for hospital deaths. Conclusions Verbal autopsy has acceptable predictive value to estimate COVID-19 deaths where disease prevalence is high and can provide data on the COVID-19 burden in countries with low testing and weak mortality surveillance where home deaths may be missed.

RESUMEN

Nano-sized silver has drawn a great deal of attention in the field of health sciences owing to its remarkable therapeutic applications. Interestingly, the method applied to synthesize nanoparticles and the choice of reagents considerably influence their therapeutic potential and toxicities. Current research has explored the toxicity, anti-inflammatory, antinociceptive, and antioxidant responses of the malonic acid-capped silver nanoparticles (MA-AgNPs (C) by using sodium borohydride as a reducing agent at low temperatures by employing both in vitro and in vivo approaches. Furthermore, it has highlighted the synergistic effect of these novel compounds with conventional anti-inflammatory therapeutic agents. Acute and sub-acute toxicity analysis performed following OECD guidelines showed that the studied MA-AgNPs (C) are safer, and prominent toxic signs have not been detected at the highest studied dose of 2,000 mg/kg. Cytotoxicity evaluation through brine shrimp lethality revealed 20% lethality at the highest concentration of 169.8 µg/mL. Significantly, positive anti-inflammatory and analgesic responses alone as well as synergism with the standard were identified through in vitro as well as in vivo methods which were more potent at a lower dose (200 mg/kg). Notably synergistic outcomes were more pronounced than individual ones, indicating their prominent effect as a feasible drug delivery system. IL-6 and TNF-α assessment in excised paw tissue through RTPCR technique further supported their anti-inflammatory potential. DPPH assay revealed eminent in vitro antioxidant activity which was further corroborated by in vivo antioxidant assessment through evaluation of SOD in excised paw tissue.

RESUMEN

Background: The incidence of anxiety in adults with spinal cord injury/disorder (SCI/D) exceeds that of the general population. Heart rate variability (HRV) biofeedback training is a potential treatment associated with a reduction in stress and anxiety, however HRV training has not been explored in the SCI/D population. Objectives: To describe a modified protocol piloting HRV training to reduce anxiety associated with SCI/D and detail the COVID-19-related modifications. Methods: To test the feasibility of the biofeedback treatment, 30 adults with SCI/D will complete this pilot randomized controlled trial. Enrollment started in January 2020, halted in March 2020 due to the COVID-19 pandemic, and resumed in March 2021 with a modified protocol. Protocol modifications are documented using the Framework for Reporting Adaptations and Modifications (FRAME). Participants are allocated to the treatment or control arm and undergo eight sessions of physiological monitoring at home using a commercially available HRV sensor and mobile application, which also delivers biofeedback training for those in the treatment arm. Surveys are administered following each session to capture self-reported stress, anxiety, and mood. The study is approved by the HCA-HealthONE institutional review board and is registered with clinicaltrials.gov (NCT# 03975075). Conclusion: COVID-19 has changed the research landscape, forcing scientists to rethink their study designs to address patient and staff safety in this new context. Our modified protocol accomplished this by moving the treatment setting and delivery out of the clinic and into the home. In doing so, we address patient and staff safety, increase external validity, and reduce participant burden.

RESUMEN

Establishing causal links between inherited polymorphisms and cancer risk is challenging. Here, we focus on the single-nucleotide polymorphism rs55705857, which confers a sixfold greater risk of isocitrate dehydrogenase (IDH)-mutant low-grade glioma (LGG). We reveal that rs55705857 itself is the causal variant and is associated with molecular pathways that drive LGG. Mechanistically, we show that rs55705857 resides within a brain-specific enhancer, where the risk allele disrupts OCT2/4 binding, allowing increased interaction with the Myc promoter and increased Myc expression. Mutating the orthologous mouse rs55705857 locus accelerated tumor development in an Idh1R132H-driven LGG mouse model from 472 to 172 days and increased penetrance from 30% to 75%. Our work reveals mechanisms of the heritable predisposition to lethal glioma in ~40% of LGG patients.

RESUMEN

Introduction Neonatal mortality is a major challenge in low-middle-income countries. The current study was conducted to assess the association between preterm cesarean delivery and fetal outcomes. Methods A prospective study was conducted at the Combined Military Hospital in Peshawar, Pakistan, from October 1, 2020, to March 31, 2021. All women reporting to the hospital with a cephalic presentation and singleton pregnancies between the 27th and 34th weeks of gestation were included in the study. Pregnancies with an abnormal presentation, those diagnosed with a congenital abnormality, and those with indications for growth restriction or preterm delivery were excluded from the study. We also excluded infants delivered via vacuum or forceps. The outcomes of interest in this study included neonatal death prior to discharge, neonatal respiratory distress, sepsis, intraventricular hemorrhage (IVH), seizure, subdural hemorrhage (SDH), or appearance, pulse, grimace, activity, and respiration (APGAR) test score of less than 7 at five minutes. Maternal features including diabetes, hypertension and gestational age of delivery, parity, previous cesarean sections (CS), and last pregnancy outcomes were documented in a predefined pro forma. Results Our sample size consisted of 288 women, who were classified into two groups. Group A comprised 144 women who gave birth vaginally and group B consisted of 144 women who underwent CS. It was observed that women who underwent cesareans had a higher likelihood of a history of hypertension and related pathologies. It was also observed that these women had a greater likelihood of being of higher age compared to women who underwent vaginal deliveries. Neonates of women who had CS were at a greater risk of presenting with respiratory distress than those who had spontaneous vaginal deliveries. Conclusion Based on our findings, respiratory distress was significantly more common in babies of women who delivered via CS. However, there was no difference in neonatal outcomes in terms of IVH, seizures, SDH, and APGAR score of <7.

RESUMEN

This study describes access to prescription medications and examines personal, financial, and structural barriers associated with access to prescription medications in patients with type 2 diabetes treated at Federally Qualified Health Centers. We used a cross-sectional design to analyze data retrieved from the 2014 Health Center Patient Survey. Adult participants who self-reported having type 2 diabetes were included in this study. Predictor variables were categorized into personal, financial, and structural barriers. Outcomes include being unable to get and delayed in getting prescription medications. Chi-square and multivariable regression models were conducted to examine associations between predictor and outcome variables. A total of 1097 participants with type 2 diabetes were included in analyses. Approximately 29% of participants were delayed, and 24% were unable to get medications. Multivariable regression results showed that personal barriers, such as federal poverty level, health status, and psychological distress were associated with being unable to get medications. Financial barriers including out-of-pocket medication cost and employment were associated with access to prescription medications. Type of health center funding program as a structural barrier was associated with access to medications. In conclusion, multi-level tailored strategies and policy changes are needed to address these barriers to improve access to prescription medications and health outcomes in underserved patient populations.
