RESUMO

Background: Adequate management of hypertension is crucial for decreasing the likelihood of cardiovascular ailments and associated complications. Nonetheless, in the Indian context, maintaining compliance with prescribed hypertensive therapies presents a notable hurdle, impeding the attainment of favorable health outcomes. Thus, this study was conducted with the aim to evaluate the prevalence of treatment adherence and explore the diverse factors that impact adherence patterns among individuals diagnosed with hypertension. Material and Methods: A community-based cross-sectional questionnaire-based study was carried out among the diagnosed hypertensive patients from 12 purposefully selected villages of Khagaul block, Patna. A total of 262 participants were recruited in the study by using non-probability sampling. The 8-item Morisky Medication Adherence Scale (MMAS-8) was used for measuring adherence. The Statistical Package for the Social Sciences (SPSS) for Windows version 21.0 (SPSS Inc; Chicago, IL, USA) was used for statistical analysis of data. Result: As per MMAS scores, 10 (3.8%) had high, 133 (50.8%) moderate, and 119 (45.4%) poor adherence. However, good adherence was reported among geriatric patients [1.65 (1.01-2.7)], those with a history of absence of comorbidities [2.15 (1.21-3.85)], more than 5 years' duration of hypertension [3.2 (1.89-5.41)], once-a-day drug intake [2.8 (1.61-4.87)], and having controlled blood pressure [5.2 (3.08-8.96)]. Controlled blood pressure (AOR = 0.048, 0.023-0.098), perception of high benefit of treatment [0.497 (0.255-0.97)], and absence of comorbidity [0.016 (0.168-0.832)] were identified as predictors of good treatment adherence. Conclusion: Overall medication adherence in the current study was 54.6%. Achieving treatment adherence frequently demands proactive patient engagement, highlighting their active role in disease management. Also, involving the patient's caregivers can offer an additional tactic to tackle non-adherence stemming from forgetfulness of the patient.

RESUMO

INTRODUCTION AND AIM: Anti-cancer treatment imparts a variety of physical impairments that cause limitations in physical functioning among women with breast cancer. The aim of the study was to explore the opinions of healthcare professionals (HCPs) working with breast cancer patients on various aspects of physical functional impairments in breast cancer patients and survivors (BCP&S). METHODOLOGY: The study was a cross-sectional survey. Taking into consideration the literature definition of 'physical function', its determinants, and literature published on relevant clinical factors in breast cancer, a survey questionnaire containing 29 questions was constructed. Thirty-seven HCPs, including physiotherapists, occupational therapists, and medical cancer experts, participated in the study. The participant's responses were obtained using a 5-point 'Agreement' Likert scale. Data analysis included a frequency table and the reliability test (Cronbach's alpha). RESULTS: The reliability of the questionnaire used in the survey was found to be acceptable (Cronbach's alpha = 0.891). The majority of the participants were of the opinion that various parameters and determinants of 'physical function' get adversely affected in BCP&S, leading to limitations in the performance of activities of daily living (e.g., dressing and bathing), particularly in elderly and frail women. Participants agreed that such impairments in physical functioning affect social and role functioning and the overall quality of life (QoL) of women with breast cancer negatively. CONCLUSION: This study found that various parameters and determinants of physical functioning are adversely affected in BCP&S, and physical functional impairments are prevalent in women with breast cancer, affecting their QoL negatively. Implications for breast cancer patients: This study points out the need for long-term surveillance of BCP&S for physical functional limitations and a proactive treatment approach to prevent such limitations.

RESUMO

Background: Athletes affected by rotator cuff tendinopathy experience discomfort, stiffness, reduced range of motion, diminished athletic performance, and decreased quality of life. This study aimed to determine the efficacy of physio-yogic exercises in reducing pain and disability, increasing range of motion, and improving quality of life in Indian overhead athletes with rotator cuff tendinopathy. Methods: Sample from 45 athletes was divided into three groups scapular recruitment exercises, physio-yogic exercises, and yoga asanas. Pre-intervention readings of the Shoulder Pain and Disability Index (SPADI), Athlete Quality of Life Scale (ALQS), and Shoulder Active Range of Motion (AROM) were taken at day 1 and post-intervention readings were taken at the end of week 8. The paired Student's t-test was used to compare the values of the outcome measures for the preintervention and postintervention within the groups. Analysis of variance was used to compare the mean values of change in the outcome measures from preintervention to postintervention between the groups. Post hoc test was conducted to compare the postintervention values of the outcome measures between the groups. Results: Total scores of SPADI (p < 0.0001), ALQS (p < 0.0001), and Shoulder AROM (p < 0.0001) demonstrated statistically significant improvements in the physio-yogic exercise group. Conclusion: The physio-yogic exercise protocol for rotator cuff tendinopathy is a unique regimen that combines the positive effects of yoga asanas and the advantages of scapular recruitment exercises. Thus, the physio-yogic exercise protocol can further promote the rehabilitation program for rotator cuff tendinopathy.

RESUMO

Background and Objective: Surgical residents face many challenges and stressors during their training. Some residents can cope better with such difficult situations, whereas others experience burnout and anxiety. Emotional intelligence (EI) and resilience are personality traits that may be associated with a better response to adverse situations. Methodology: A cross-sectional analytical study using validated questionnaires the Schutte Self-report EI Test (SSEIT) and the Connor-Davidson Resilience Scale (CD-RISC-25) was conducted to assess EI and resilience among the participants. Data were collected through the hard copies of the questionnaires, compiled using Microsoft Excel and analyzed using SPSS version 26. P < 0.5 was considered significant. The scores of EI and resilience were compared to evaluate the relationship between them. Results: A correlation analysis was performed between EI and resilience by comparing the scores obtained from SSEIT and CD-RISC. Our analysis revealed a strong positive correlation between EI and resilience (r = 0.59, P < 0.0001). Conclusion: Based on our results, we can say that EI and resilience are positively correlated. This means that an emotionally intelligent person should exhibit a resilient behavior.

RESUMO

Introduction The emergence of coronavirus disease 2019 (COVID-19) posed significant challenges to global health, leading to the declaration of a pandemic by the World Health Organization. Vaccination efforts have effectively reduced severe outcomes and mortality, but breakthrough infections and new variants are of concern. In response, annual booster doses of COVID-19 vaccines are being considered to maintain immunity. Healthcare professionals, as frontline workers, play a pivotal role in vaccination campaigns. This study explores their attitudes toward and willingness to accept annual COVID-19 booster doses in India. Methods A pan-India cross-sectional survey was conducted among healthcare professionals, including faculty, resident doctors, interns, and nursing staff, across Indian medical and nursing colleges. Convenience sampling was used to collect responses via an online questionnaire. The questionnaire assessed demographics, vaccine status, attitudes toward COVID-19 vaccination, and willingness to accept annual booster doses. Multivariate analysis was performed to identify predictors of booster dose acceptance. Results A total of 535 participants responded from 28 states and 8 union territories of India. Most were 34.2 years (± 11.1 SD), and 372 (69.5%) had taken Covishield (Serum Institute of India, Pune, India) as their primary vaccine. While 525 (98.1%) had taken the first dose and 518 (96.8%) of them had taken the second dose, only 333 (62.2%) had received a booster. Around 318 (60%) of healthcare professionals were willing to accept an annual booster dose. The mean attitude score toward annual booster doses was 75.4 (range: 28-111). Healthcare professionals' trust in government recommendations and medical experts significantly influenced their willingness to accept annual booster doses. Conclusion This study provides insights into the attitudes of healthcare professionals in India toward annual COVID-19 booster doses. At the same time, a significant proportion showed a willingness to accept boosters.

RESUMO

BACKGROUND: Chronic lymphatic filariasis patients in Bihar, India, need management of lymphedema to live a disability-free life. For patients who have recurrent attacks of acute dermato-lymphangio-adenitis (ADLA), World Health Organization (WHO) has recommended simple home-based measures that include maintaining hygiene, skin care, and limb movement. However, patients in rural areas are unable to adopt them, resulting in a vicious cycle of ADLA attacks. There might be multiple realities from patients' and healthcare workers' perspectives that were unexplored. Qualitative research was deemed best suitable to identify the barriers to carrying out home-based lymphedema practices that adversely affected quality of life. METHODS: The qualitative descriptive study was conducted in two villages in the rural field practice area under a tertiary care hospital in Bihar. Researchers purposively selected ten participants, including patients affected by lymphedema, their caregivers, the grassroots healthcare workers, and the block health manager. In-depth interviews were conducted using a semi-structured interview guide. Data were entered into QDA Miner Lite, where researchers did attribute, in-vivo, process, descriptive, emotion, and holistic coding, followed by content analysis, where categories and themes emerged from the codes. RESULTS: Three themes emerged: the inherent nature of disease, patient-related factors, and healthcare system-related factors. The fifteen identified barriers were low awareness, low adherence, low health-seeking behavior, poor personal hygiene, and categories like signs and symptoms, seasonal factors, hampered activities of daily living, hopelessness from not getting cured, psychosocial difficulty, lack of capacity building and receipt of incentives by healthcare workers, unavailability of laboratory diagnosis and management of complications at the facility, inconsistent drug supply, and no financial assistance. CONCLUSIONS: Accessibility to WaSH, regular training of home-based care, increasing the capacity and motivation of grassroots workers, and the generation of in-depth awareness among the patients are required to achieve the elimination of filariasis, with MMDP as a key component of that strategy for endemic districts across the whole country.

RESUMO

The ability of tumors to survive therapy reflects both cell-intrinsic and microenvironmental mechanisms. Across many cancers, including triple-negative breast cancer (TNBC), a high stroma/tumor ratio correlates with poor survival. In many contexts, this correlation can be explained by the direct reduction of therapy sensitivity induced by stroma-produced paracrine factors. We sought to explore whether this direct effect contributes to the link between stroma and poor responses to chemotherapies. In vitro studies with panels of TNBC cell line models and stromal isolates failed to detect a direct modulation of chemoresistance. At the same time, consistent with prior studies, fibroblast-produced secreted factors stimulated treatment-independent enhancement of tumor cell proliferation. Spatial analyses indicated that proximity to stroma is often associated with enhanced tumor cell proliferation in vivo. These observations suggested an indirect link between stroma and chemoresistance, where stroma-augmented proliferation potentiates the recovery of residual tumors between chemotherapy cycles. To evaluate this hypothesis, a spatial agent-based model of stroma impact on proliferation/death dynamics was developed that was quantitatively parameterized using inferences from histologic analyses and experimental studies. The model demonstrated that the observed enhancement of tumor cell proliferation within stroma-proximal niches could enable tumors to avoid elimination over multiple chemotherapy cycles. Therefore, this study supports the existence of an indirect mechanism of environment-mediated chemoresistance that might contribute to the negative correlation between stromal content and poor therapy outcomes. SIGNIFICANCE: Integration of experimental research with mathematical modeling reveals an indirect microenvironmental chemoresistance mechanism by which stromal cells stimulate breast cancer cell proliferation and highlights the importance of consideration of proliferation/death dynamics. See related commentary by Wall and Echeverria, p. 3667.

RESUMO

INTRODUCTION: This study presents a comprehensive assessment of healthcare facilities, focusing on workforce composition, operational dynamics, diagnostic laboratory services, and accessibility considerations. The comparison between government and private healthcare sectors provides insights into service delivery and potential disparities. The study's rationale, objectives, and methodology are explored in the context of the Indian healthcare landscape. METHODS: A cross-sectional analysis was conducted in Muzaffarpur district, Bihar, targeting selected urban and rural blocks. The study employed geolocation data to analyze accessibility to healthcare facilities. Data collection involved on-site visits, structured questionnaires, and consultation of the Indian Council of Medical Research (ICMR)'s framework. The assessment concentrated on the availability of tests offered by the LaBike platform, and workforce compositions were compared. RESULTS: Government healthcare facilities exhibited a balanced distribution of doctors, nurses, and grassroot workers, reflecting comprehensive healthcare provisions. Private facilities, although featuring moderate doctor and nurse presence, lacked grassroot workers. Diagnostic test prevalence was evident, with core tests, such as CBC and blood glucose, available in over 85% of facilities. Government facilities provided tests free of charge, while private facilities showcased a diverse cost spectrum. Proposed interventions received strong support from both sectors, indicating the potential for innovative healthcare solutions. Accessibility analysis: Urban intervention and control sites demonstrated comparable accessibility, with facilities located within 2 km. In rural intervention and control sites, distances varied significantly. Mushahari, a rural intervention site, required participants to travel 6 km to the nearest facility, impacting healthcare access. By contrast, Marwan, a rural control site, featured a shorter distance of 3 km. CONCLUSION: This study's comprehensive evaluation of healthcare facilities offers valuable insights into workforce dynamics, diagnostic services, and healthcare interventions in the context of government and private sectors. The findings underscore the significance of addressing workforce gaps and promoting equitable access to diagnostics. By informing evidence-based decision-making, this study contributes to the optimization of healthcare service delivery, aiming to enhance healthcare quality and accessibility for all.

RESUMO

Background Port site morbidities after laparoscopic cholecystectomy may be related to the port used for the extraction of the gallbladder. Prior randomized trials that tried to address the suitable port for gallbladder extraction showed mixed results favouring epigastric, whereas others favoured umbilical. Thus, the present study was conducted with the aim of finding a suitable port for gallbladder extraction after laparoscopic cholecystectomy. Methodology A total of 104 patients undergoing laparoscopic cholecystectomy were randomized to either the epigastric (Group 1) or umbilical (Group 2) port group for gallbladder extraction. Post-operative pain (by visual analogue scale (VAS)), the frequency of surgical site infection (SSI), and port site herniation were compared. Results Post-operative pain was lower in the umbilical port group in the initial 24 hours. The SSIs and port site herniation rates were lower in the umbilical port group; however, they were statistically not significant. Conclusion Less post-operative pain at the umbilical port may help with the early discharge of patients. In contrast to other studies, our trial had fewer infections and hernias in the umbilical port group.

RESUMO

The soluble urokinase plasminogen activator receptor (suPAR) has been proposed as a biomarker for risk stratification of patients presenting with acute infections. However, most studies evaluating suPAR have used platform-based assays, the accuracy of which may differ from point-of-care tests capable of informing timely triage in settings without established laboratory capacity. Using samples and data collected during a prospective cohort study of 425 patients presenting with moderate Covid-19 to two hospitals in India, we evaluated the analytical performance and prognostic accuracy of a commercially-available rapid diagnostic test (RDT) for suPAR, using an enzyme-linked immunosorbent assay (ELISA) as the reference standard. Our hypothesis was that the suPAR RDT might be useful for triage of patients presenting with moderate Covid-19 irrespective of its analytical performance when compared with the reference test. Although agreement between the two tests was limited (bias = -2.46 ng/mL [95% CI = -2.65 to -2.27 ng/mL]), prognostic accuracy to predict supplemental oxygen requirement was comparable, whether suPAR was used alone (area under the receiver operating characteristic curve [AUC] of RDT = 0.73 [95% CI = 0.68 to 0.79] vs. AUC of ELISA = 0.70 [95% CI = 0.63 to 0.76]; p = 0.12) or as part of a published multivariable prediction model (AUC of RDT-based model = 0.74 [95% CI = 0.66 to 0.83] vs. AUC of ELISA-based model = 0.72 [95% CI = 0.64 to 0.81]; p = 0.78). Lack of agreement between the RDT and ELISA in our cohort warrants further investigation and highlights the importance of assessing candidate point-of-care tests to ensure management algorithms reflect the assay that will ultimately be used to inform patient care. Availability of a quantitative point-of-care test for suPAR opens the door to suPAR-guided risk stratification of patients with Covid-19 and other acute infections in settings with limited laboratory capacity.

RESUMO

OBJECTIVES: Coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) has emerged as a formidable infection in patients with COVID-19. The aggressive management of CAM affects quality of life (QOL); thus, this study was designed to assess the QOL in patients with CAM at a tertiary healthcare institution. METHODS: This cross-sectional study of 57 patients with CAM was conducted over 6 months using a semi-structured standard questionnaire (the abbreviated World Health Organization Quality of Life questionnaire [WHO-BREF]) and a self-rated improvement (SRI) scale ranging from 0 to 9. Cut-off values of ≤52 and <7 were considered to indicate poor QOL and poor improvement, respectively. The correlations of QOL and SRI scores were evaluated using Spearman rho values. RESULTS: In total, 27 patients (47.4%; 95% confidence interval [CI], 34.9%-60.1%) and 26 patients (45.6%; 95% CI, 33.4%-58.4%) had poor QOL and poor SRI scores, respectively. The overall median (interquartile range) QOL score was 52 (41-63). Headache (adjusted B, -12.3), localized facial puffiness (adjusted B , -16.4), facial discoloration (adjusted B, -23.4), loosening of teeth (adjusted B, -18.7), and facial palsy (adjusted B, -38.5) wer e significantly associated with the QOL score in patients with CAM. CONCLUSION: Approximately 1 in 2 patients with CAM had poor QOL and poor improvement. Various CAM symptoms were associated with QOL in these patients. Early recognition is the key to optimal treatment, improved outcomes, and improved QOL in patients with CAM.

RESUMO

Background: Incomplete spinal cord injury (iSCI) often results in impaired balance leading to functional impairments. Recovery of standing balance ability is an important aim of rehabilitative programs. However, limited information is available on effective balance training protocols for individuals with iSCI. Objectives: To assess the methodological quality and effectiveness of various rehabilitation interventions for improving standing balance in individuals with iSCI. Methods: A systematic search was performed in SCOPUS, PEDro, PubMed, and Web of Science from inception until March 2021. Two independent reviewers screened articles for inclusion, extracted data, and evaluated methodological quality of the trials. PEDro Scale was used to assess the quality of randomized controlled trials (RCT) and crossover studies while pre-post trials were assessed using the modified Downs and Black tool. A meta-analysis was performed to quantitatively describe the results. The random effects model was applied to present the pooled effect. Results: Ten RCTs with a total of 222 participants and 15 pre-post trials with 967 participants were analyzed. The mean PEDro score and modified Downs and Black score was 7/10 and 6/9, respectively. The pooled standardized mean difference (SMD) for controlled and uncontrolled trials of body weight-supported training (BWST) interventions was -0.26 (95% CI, -0.70 to 0.18; p = .25) and 0.46 (95% CI, 0.33 to 0.59; p < .001), respectively. The pooled effect size of -0.98 (95% CI, -1.93 to -0.03; p = .04) indicated significant improvements in balance after a combination of BWST and stimulation. Pre-post studies analyzing the effect of virtual reality (VR) training interventions on Berg Balance Scale (BBS) scores in individuals with iSCI reported a mean difference (MD) of 4.22 (95% CI, 1.78 to 6.66; p = .0007). Small effect sizes were seen in pre-post studies of VR+stimulation and aerobic exercise training interventions indicating no significant improvements after training on standing balance measures. Conclusion: This study demonstrated weak evidence to support the use of BWST interventions for overground training for balance rehabilitation in individuals with iSCI. A combination of BWST with stimulation however showed promising results. There is a need for further RCTs in this field to generalize findings. Virtual reality-based balance training has shown significant improvement in standing balance post iSCI. However, these results are based on single group pre-post trials and lack appropriately powered RCTs involving a larger sample size to support this intervention. Given the importance of balance control underpinning all aspects of daily activities, there is a need for further well-designed and appropriately powered RCTs to evaluate specific features of training interventions to improve standing balance function in iSCI.

The model was quantitatively parameterized using inferences from histological analyses and experimental studies. We found that the observed enhancement of tumor cell proliferation within stroma-proximal niches can enable tumors to avoid elimination over multiple chemotherapy cycles. Therefore, our study supports the existence of a novel, indirect mechanism of environment-mediated chemoresistance that might contribute to the negative correlation between stromal content and poor therapy outcomes.

RESUMO

Immune checkpoint blockers (ICBs) have failed in all phase III glioblastoma trials. Here, we found that ICBs induce cerebral edema in some patients and mice with glioblastoma. Through single-cell RNA sequencing, intravital imaging, and CD8+ T cell blocking studies in mice, we demonstrated that this edema results from an inflammatory response following antiprogrammed death 1 (PD1) antibody treatment that disrupts the blood-tumor barrier. Used in lieu of immunosuppressive corticosteroids, the angiotensin receptor blocker losartan prevented this ICB-induced edema and reprogrammed the tumor microenvironment, curing 20% of mice which increased to 40% in combination with standard of care treatment. Using a bihemispheric tumor model, we identified a "hot" tumor immune signature prior to losartan+anti-PD1 therapy that predicted long-term survival. Our findings provide the rationale and associated biomarkers to test losartan with ICBs in glioblastoma patients.

RESUMO

Low back pain (LBP) is a common problem encountered among women worldwide. This research aimed at the cross-cultural translation, adaptation, and equivalence assessment of the Low Back Pain Knowledge Questionnaire (LBPKQ) in the Hindi language. The LBPKQ, originally in English (E-LBPKQ) was translated and validated in the Hindi language (H-LBPKQ). The forward-backward procedure was adapted from the recommended guidelines for cross-cultural adaptation of measures. Psychometric properties of the H-LBPKQ were evaluated among 250 Hindi-speaking Indian women with LBP. Test-retest reliability was evaluated in the first 161 participants of the study sample. The overall LBPKQ scores obtained a mean of 3.1 ± 1.1. The internal consistency was excellent for both E-LBPKQ and H-LBPKQ, with Cronbach's alpha of 0.983 (95% confidence interval [CI], 0.980-0.986) and 0.975 (95% CI, 0.970-0.979), respectively. Construct validity was good, with Kaiser-Meyer-Olkin value of 0.892 for E-LBPKQ and 0.852 for H-LBPKQ. Bartlett's test of sphericity (P < .0001) was significant for E-LBPKQ and H-LBPKQ. Two factors were extracted through principal component analysis. The H-LBPKQ is valid and reliable to assess LBP knowledge among Hindi speaking population. Low LBPKQ scores indicate poor LBP knowledge; hence, LBP sensitization is needed among Indian women.

RESUMO

PURPOSE: This feasibility study examined the aggression management training (AMT) interventions on self-esteem, impulsivity, and aggressive behavior among adolescents residing in delinquent or observation homes. METHODS: A quantitative research approach with the quasi-experimental nonequivalent control group (comparison) pretest and Posttest design was adopted. A total of 32 male adolescents (16 each in experimental and comparison groups) residing in two different observation homes in the state of Bihar, India were selected by convenience sampling technique. The study evaluated the following outcome measures: self-esteem, impulsivity, and aggressive behavior for both groups at baseline and 1 month. AMT was administered to the experimental group bi-weekly for 4 weeks covering four components in 8 sessions. RESULTS: We analysed the data with independent and paired t-tests for between and within the group differences, and Pearson correlation for a relationship. AMT intervention improved self-esteem and reduced aggressive behavior and impulsivity among adolescents residing in delinquent homes. A correlation was found between aggression and impulsivity, and between self-esteem and impulsivity. PSYCHIATRIC NURSING IMPLICATIONS: The study had provided initial evidence for practice that can help psychiatric nurses significantly implement these types of interventions among significant, vulnerable, and ignored groups of adolescents detained in observation homes to prevent the occurrence of repeat offenses.

RESUMO

Background: Adolescence is the most complex stage of development that causes the greatest difficulties in their life because of frequent physical and emotional issues including deviated character and behavioral disorders. Aim: This descriptive comparative study was intended to compare self-esteem between heinous and non-heinous male delinquent adolescents residing in observation homes. Materials and Methods: A quantitative research approach with a non-experimental descriptive comparative design was adopted. One hundred and seventy-nine male delinquent adolescents (Heinous = 74, Non-Heinous = 105) residing in two observation homes were selected by convenience sampling technique based on the type of crime committed. The standardized Rosenberg's self-esteem scale was used to collect the data. Results: We analyzed the data with Chi-square for homogeneity of sample characteristics, an independent t test for comparison of self-esteem between groups, an independent t test, one-way ANOVA for the association, and stepwise regression for predictors. There was a statistically significant difference in self-esteem between groups, a significant association of self-esteem with age and duration of stay in the heinous group and with the father's education in the non-heinous group, and the father's education, mother's occupation, substance use, and order of birth had predicted the self-esteem in non-heinous group. Conclusion: The study concluded that self-esteem significantly varied between heinous and non-heinous group delinquents. This study is the first of its kind and provided initial evidence by filling the gap in the literature to understand the difference in the level of self-esteem among delinquent adolescents according to the type of crime committed.

RESUMO

Efficient resource allocation is essential for effective pandemic response. We measured host biomarkers in 420 patients presenting with moderate coronavirus disease 2019 and found that different biomarkers predict distinct clinical outcomes. Interleukin (IL)-1ra, IL-6, IL-10, and IL-8 exhibit dose-response relationships with subsequent disease progression and could potentially be useful for multiple use-cases.
