RESUMO

Health literacy (HL) is crucial in achieving the Sustainable Development Goal of reducing one-third of premature mortality by 2030 from Non-Communicable Diseases (NCDs) and improving Universal Health Coverage. Low health literacy is linked to poor health outcomes, and evidence shows that levels of limited HL are high, even among highly educated individuals. This study aims to assess HL levels and related factors among patients with NCDs at Tribhuvan University Teaching Hospital (TUTH) in Nepal. A cross-sectional survey was conducted at TUTH among 303 patients with NCDs with Cardiovascular Diseases, Chronic Obstructive Pulmonary Disease, Diabetes Mellitus, Hypertension, Epilepsy, Asthma and Cancer who came for follow-up from December 2022 to February 2023. Data was collected via face-to-face interviews by the trained enumerators using a structured Health Literacy Questionnaire (HLQ) containing 44 items (divided into nine domains). Multivariate logistic regression analysis was performed using SPSS version 26, with statistical significance at 0.05, to determine the associated factors of HL. The mean ±SD age of the respondents was 47.4±16.18 years. More than half of the respondents were female (56.1%). The patients had higher HL in all HL domains except 'Navigating the healthcare system'. Educational status was significantly associated with six out of nine HL domains. Co-morbidity, attendance at health-related seminars, regular physical activity, and social connectedness were associated with at least one of the domains of HL. This study identified the important factors of HL, such as socio-demographic and medical factors among patients with NCDs. This highlights the need for a comprehensive approach to address identified gaps in HL, considering its multifaceted and composite nature and promoting interventions to improve HL in high-risk populations.

RESUMO

BACKGROUND: The Life-Space Assessment (LSA) is an instrument that measures mobility in older adults as they reach different areas, defined as life-spaces extending from home to beyond towns or regions. The purpose of the study was to develop the Hindi version of the LSA (LSA- H) and to investigate the validity and reliability of the Hindi version as well as its cultural adaptation. METHODS: A cross-sectional study of two hundred forty-five older adults participated in the study from four different study practice areas. Following forward backwards translation, the LSA-H was developed, and the scores were correlated with those of the Activities-Specific Balance Confidence Scale Hindi (ABC- H), the Physical Health Subscale of the WHO-BREF Questionnaire and the Geriatric Depression Scale: Short Form Hindi (GDS-SFH) to test the criterion and concurrent validity. RESULTS: The mean score and standard deviation of the LSA-H questionnaire were 56.53 ± 35.99, those of the Physical Health Subscale of the WHO-BREF instrument were 18.54 ± 7.87, those of the GDS-SFH questionnaire were 6.95 ± 4.21 and those of the ABC- H questionnaire were 54.40 ± 28.96. The Pearson correlation coefficient (r) between the LSA-H score and ABC-H score was 0.707 (p value < 0.0001), that between the LSA-H score and the Physical Health Subscale of the WHO-BREF was 0.766 (p value < 0.0001), and that between the LSA-H score and GDS-SFG score was - 0.674 (p value < 0.0001). CONCLUSION: This study demonstrated that the Hindi version of the LSA is a valid and reliable instrument for assessing living space among older adults in the Hindi language in an Indian population. Furthermore, the LSA-H was significantly correlated with other health assessment tools in terms of functional mobility, general health status and mental well-being.

RESUMO

Background: Substance use is a complex condition with multidimensional determinants. The present study aims to find the prevalence and determinants of substance use among young people attending primary healthcare centers in India. Methods: A multicentric cross-sectional study was conducted across 15 states in India on 1,630 young people (10-24 years) attending primary health centers. The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) was used to capture data on substance use. The degree of substance involvement was assessed and multivariate regression analysis was conducted to determine the risk factors of substance use. Results: The prevalence of substance use was 32.8%, with a median substance initiation age of 18 years. Among the substance users, 75.5% began before completing adolescence. Tobacco (26.4%), alcohol (26.1%) and cannabis (9.5%) were commonly consumed. Sociodemographic determinants included higher age, male gender, urban residence, positive family history, northeastern state residence and lower socioeconomic class. Over 80% of users had moderate or high involvement. Conclusions: High substance use prevalence among young people in Indian healthcare centers underscores the urgency of targeted intervention. Insights on determinants guide effective prevention strategies for this complex public health issue.

RESUMO

The presence of air in the peritoneal cavity demonstrated radiographically as the crescent of air under the diaphragm is termed pneumoperitoneum. The causative agents may be divided into spontaneous, traumatic, iatrogenic, and miscellaneous. The majority (∼ 90%) of cases are attributed to hollow viscus perforation which requires immediate surgical attention. Neonatal pneumoperitoneum is a surgical emergency unless proven otherwise. A distinct entity termed benign pneumoperitoneum occurs in the absence of clinical and paraclinical features of peritonitis. Benign pneumoperitoneum may be caused by various thoracic, abdominal, and gynecological conditions. In neonates with respiratory distress pneumoperitoneum is a frequent association especially when treated with mechanical ventilation. The air leak phenomenon leads to air tracking from the ruptured alveoli along the interstitium to the mediastinum then to the retroperitoneum and ultimately into the peritoneal cavity. Such patients usually do not require surgical intervention and are managed conservatively. Knowledge of the existence of benign pneumoperitoneum helps to avoid unnecessary surgery thereby reducing operative morbidity and mortality.

RESUMO

Repeated serological testing tells about the change in the overall infection in a community. This study aimed to evaluate changes in antibody prevalence and kinetics in a closed cohort over six months in different sub-populations in India. The study included 10,000 participants from rural and urban areas in five states and measured SARS-CoV-2 antibodies in serum in three follow-up rounds. The overall seroprevalence increased from 73.9% in round one to 90.7% in round two and 92.9% in round three. Among seropositive rural participants in round one, 98.2% remained positive in round two, and this percentage remained stable in urban and tribal areas in round three. The results showed high antibody prevalence that increased over time and was not different based on area, age group, or sex. Vaccinated individuals had higher antibody prevalence, and nearly all participants had antibody positivity for up to six months.

RESUMO

This study highlights the significance of testicular adrenal rest tumors (TARTs) in the context of congenital adrenal hyperplasia (CAH). The case report of an 11-year-old male with bilateral scrotal enlargement underscores the diagnostic challenges and complexities involved. Through thorough clinical, radiological, and hormonal assessments, we elucidate the pathophysiology, prevalence, and potential impact on fertility. Early detection and management of TARTs are crucial for preserving testicular function. Regular scrotal ultrasound screenings are recommended to avert long-term complications in male CAH patients.

RESUMO

Background: High levels of stress among pregnant women have been reported during the coronavirus disease 2019 (COVID-19) pandemic because of various infection-related and lockdown measures. Concerns about safe delivery, breastfeeding, and child care may increase the risk of depression in vulnerable women during the perinatal period. Aim: To study the perceptions regarding child care and prevalence of perinatal depression during the COVID-19 pandemic. Materials and Methods: A cross-sectional community-based survey was conducted among 750 lactating mothers post delivery between September 2020 and February 2021 in 51 districts of Uttar Pradesh. A convenient purposive sampling technique was used. A semi-structured questionnaire was used to collect the socio-demographic details and perceptions regarding child care during the COVID-19 pandemic. Assessment of depression symptoms was performed with the help of patient health questionnaire 9 (PHQ-9). Results: A total of 440 participants were suffering from some form of depression symptoms; the majority had mild depression. Depression was found to be higher among homemakers and young mothers (age <25 years). Depression was found in more than 40% of the respondents who felt fear of COVID infection during breast feeding and hospital stay. Similarly, more than 50% of the respondents who feared unavailability of timely health services and social ignorance had depression. More than 60% of the mothers who did not have any knowledge about safe breast-feeding and child care practices had some form of depression, and the results were statistically significant. Conclusions: Perinatal depression is highly prevalent during the ongoing pandemic. Hence, regular screening, psychoeducation, awareness regarding safe breast feeding, and child care practices are recommended.

RESUMO

Background: Estimating seroepidemiolgical prevalence of SARS-CoV-2 antibody is an essential public health strategy. There is insufficient evidence of prevalence among those belonging to young age population in India. Objective: To compare the SARS-CoV-2 seropositivity rate between children and adults in selected sites from India. Materials and Methods: This was a multicentric population-based seroepidemiological study conducted in selected urban and rural areas of five sites selected from four states (Delhi, Odisha, Uttar Pradesh, Tripura) of India. Participants aged ≥1 year were included from different clusters of each area. Total serum antibody against SARS-CoV-2 virus was assessed qualitatively by using a standard enzyme-linked immunosorbent assay (ELISA) kit. Results: Data collection period was from 15 March 2021 to 10 June 2021. Total available data was of 4509 participants, of whom 700 were <18 years of age and 3809 were ≥18 years of age. The site-wise number of available data among those aged 2-17 years was 92, 189, 165, 146 and 108 for the sites of Delhi urban, Delhi rural, Bhubaneswar rural, Gorakhpur rural and Agartala rural area, respectively. The seroprevalence was 55.7% in the <18 years age group and 63.5% in the ≥18 years age group. The prevalence among female children was 58% and among male children was 53%. Conclusion: SARS-CoV-2 seropositivity rate among children was high and comparable to that of the adult population. Hence, it is unlikely that any future third wave by prevailing SARS-CoV-2 variant would disproportionately infect children 2 years or older.

RESUMO

Intervertebral disc (IVD) degeneration (IVDD) is a leading cause of chronic low back pain. There is a strong clinical demand for more effective treatments for IVDD as conventional treatments provide only symptomatic relief rather than arresting IVDD progression. This study shows that senolytic therapy with local drug delivery can inhibit IVDD and restore IVD integrity. ABT263, a senolytic drug, is loaded in poly(lactic-co-glycolic acid) nanoparticles (PLGA-ABT) and intradiscally administered into injury-induced IVDD rat models. The single intradiscal injection of PLGA-ABT may enable local delivery of the drug to avascular IVD, prevention of potential systemic toxicity caused by systemic administration of senolytic drug, and morbidity caused by repetitive injections of free drug into the IVD. The strategy results in the selective elimination of senescent cells from the degenerative IVD, reduces expressions of pro-inflammatory cytokines and matrix proteases in the IVD, inhibits progression of IVDD, and even restores the IVD structure. This study demonstrates for the first time that local delivery of senolytic drug can effectively treat senescence-associated IVDD. This approach can be extended to treat other types of senescence-associated degenerative diseases.

RESUMO

In research on various central nervous system injuries, bazedoxifene acetate (BZA) has shown two main effects: neuroprotection by suppressing the inflammatory response and remyelination by enhancing oligodendrocyte precursor cell differentiation and oligodendrocyte proliferation. We examined the effects of BZA in a rat spinal cord injury (SCI) model. Anti-inflammatory and anti-apoptotic effects were investigated in RAW 264.7 cells, and blood-spinal cord barrier (BSCB) permeability and angiogenesis were evaluated in a human brain endothelial cell line (hCMEC/D3). In vivo experiments were carried out on female Sprague Dawley rats subjected to moderate static compression SCI. The rats were intraperitoneally injected with either vehicle or BZA (1mg/kg pre-SCI and 3 mg/kg for 7 days post-SCI) daily. BZA decreased the lipopolysaccharide-induced production of proinflammatory cytokines and nitric oxide in RAW 264.7 cells and preserved BSCB disruption in hCMEC/D3 cells. In the rats, BZA reduced caspase-3 activity at 1 day post-injury (dpi) and suppressed phosphorylation of MAPK (p38 and ERK) at dpi 2, hence reducing the expression of IL-6, a proinflammatory cytokine. BZA also led to remyelination at dpi 20. BZA contributed to improvements in locomotor recovery after compressive SCI. This evidence suggests that BZA may have therapeutic potential to promote neuroprotection, remyelination, and functional outcomes following SCI.

RESUMO

Background The advent of the second wave of coronavirus disease 2019 (COVID-19) in India caused a new range of challenges in diagnosing the virus. Various point-of-care tests have been introduced for rapid diagnosis. Although rapid antigen tests are the most commonly used, the false-negative rates are high. Therefore, the purpose of this study was to compare the positivity rate of real-time polymerase chain reaction (RT-PCR) testing in rapid antigen-negative cases of COVID-19 during the first and second waves of the COVID-19 pandemic. Methodology This was an observational study conducted in the Department of Microbiology, All India Institute of Medical Sciences, Gorakhpur. Results In total, 2,168 patients were tested. The percentage positivity rate of the RT-PCR tests among the antigen-negative samples was 4.34% in the first wave of the pandemic whereas it was 8.08% in the second wave. Conclusions The main conclusion of this study was that antigen tests should never be used alone for the diagnosis of COVID-19. Instead, they should be confirmed with a RT-PCR test.

RESUMO

Background Public health interventions are epidemiologically sound and cost-effective methods to control disease burden. Non-pharmacological public health interventions are the only mode to control diseases in the absence of medication. Objective To find the impact of public health interventions on the epidemiological indicators of disease progression. Methods This is a secondary data analysis done on COVID-19 data. The median doubling time and R0 were calculated for a rolling period of seven days. Interventions were scored from zero to three with an increasing level of stringency. Multivariate linear regression was performed to find the role of individual interventions on R0 and the median doubling time. Results The highest intervention score was reported in the lockdown phase, which gradually decreased to the lowest level of 22. The R0 values settled to a level of 1.25, and the median doubling time increased to 20 days at the end of the study. Public awareness and public health laws were found to be related to both R0 and the median doubling time in the pre-lockdown phase only. Conclusion The implementation of interventions at the ground level is one of the key factors in the success of public health interventions. Post implementation, poor effectiveness of many interventions is evident from the study. Further, studies related to the sequence of interventions are required to further analyze the poor effect of the interventions.

RESUMO

Neuropathic pain (NP) is a complex, debilitating, chronic pain state, heterogeneous in nature and caused by a lesion or disease affecting the somatosensory system. Its pathogenesis involves a wide range of molecular pathways. NP treatment is extremely challenging, due to its complex underlying disease mechanisms. Current pharmacological and nonpharmacological approaches can provide long-lasting pain relief to a limited percentage of patients and lack safe and effective treatment options. Therefore, scientists are focusing on the introduction of novel treatment approaches, such as stem cell therapy. A growing number of reports have highlighted the potential of stem cells for treating NP. In this review, we briefly introduce NP, current pharmacological and nonpharmacological treatments, and preclinical studies of stem cells to treat NP. In addition, we summarize stem cell mechanisms-including neuromodulation in treating NP. Literature searches were conducted using PubMed to provide an overview of the neuroprotective effects of stem cells with particular emphasis on recent translational research regarding stem cell-based treatment of NP, highlighting its potential as a novel therapeutic approach.

RESUMO

Resolvins, a new family from the endogenous specialized pro-resolving mediators (SPMs), promote the resolution of the inflammatory response. Resolvin D3 (RvD3), a docosahexaenoic acid (DHA) product, has been known to suppress the inflammatory response. However, the anti-inflammatory and neuroprotective effects of RvD3 are not known in a model of spinal cord injury (SCI). Here, we investigated the anti-inflammatory and neuroprotective effect of RvD3 in a mouse model of SCI. Processes associated with anti-inflammation and angiogenesis were studied in RAW 264.7 cells and the human brain endothelial cell line hCMEC/D3, respectively. Additionally, female C57BL/6 mice were subjected to moderate compression SCI (20-g weight compression for 1 min) followed by intrathecal injection of vehicle or RvD3 (1 µg/20 µL) at 1 h post-SCI. RvD3 decreased the lipopolysaccharide (LPS)-induced production of inflammatory mediators and nitric oxide (NO) in RAW 264.7 cells and promoted an angiogenic effect in the hCMEC/D3 cell line. Treatment with RvD3 improved locomotor recovery and reduced thermal hyperalgesia in SCI mice compared with vehicle treatment at 14 days post-SCI. Remarkably, RvD3-treated mice exhibited reduced expression of inflammatory cytokines (TNF-α, IL6, IL1ß) and chemokines (CCL2, CCL3). Also, RvD3-treated mice exhibited increased expression of tight junction proteins such as zonula occludens (ZO)-1 and occludin. Furthermore, immunohistochemistry showed a decreased level of gliosis (GFAP, Iba-1) and neuroinflammation (CD68, TGF-ß) and enhanced neuroprotection. These data provide evidence that intrathecal injection of RvD3 represents a promising therapeutic strategy to promote inflammatory resolution, neuroprotection, and neurological functional recovery following SCI.

RESUMO

Spinal fusion has become a common surgical technique to join two or more vertebrae to stabilize a damaged spine; however, the rate of pseudarthrosis (failure of fusion) is still high. To minimize pseudarthrosis, bone morphogenetic protein-2 (BMP2) has been approved for use in humans. In this study, we developed a poly(lactide-co-glycolide) (PLGA) composite incorporated with magnesium hydroxide (MH) nanoparticles for the delivery of BMP2. This study aimed to evaluate the effects of released BMP2 from BMP2-immobilized PLGA/MH composite scaffold in an in vitro test and an in vivo mice spinal fusion model. The PLGA/MH composite films were fabricated via solvent casting technique. The surface of the PLGA/MH composite scaffold was modified with polydopamine (PDA) to effectively immobilize BMP2 on the PLGA/MH composite scaffold. Analyzes of the scaffold revealed that using PLGA/MH-PDA improved hydrophilicity, degradation performance, neutralization effects, and increased BMP2 loading efficiency. In addition, releasing BMP2 from the PLGA/MH scaffold significantly promoted the proliferation and osteogenic differentiation of MC3T3-E1 cells. Furthermore, the pH neutralization effect significantly increased in MC3T3-E1 cells cultured on the BMP2-immobilized PLGA/MH scaffold. In our animal study, the PLGA/MH scaffold as a BMP2 carrier attenuates inflammatory responses and promotes BMP2-induced bone formation in posterolateral spinal fusion model. These results collectively demonstrate that the BMP2-immobilized PLGA/MH scaffold offers great potential in effectively inducing bone formation in spinal fusion surgery.

RESUMO

Intervertebral disc (IVD) degeneration is one of the predominant causes of chronic low back pain (LBP), which is a leading cause of disability worldwide. Despite substantial progress in cell therapy for the treatment of IVD degeneration, significant challenges remain for clinical application. Here, we investigated the effectiveness of hyaluronan-methylcellulose (HAMC) hydrogels loaded with Wharton's Jelly-derived mesenchymal stromal cell (WJ-MSCs) in vitro and in a rat coccygeal IVD degeneration model. Following induction of injury-induced IVD degeneration, female Sprague-Dawley rats were randomized into four groups to undergo a single intradiscal injection of the following: (1) phosphate buffered saline (PBS) vehicle, (2) HAMC, (3) WJ-MSCs (2 × 104 cells), and (4) WJ-MSCs-loaded HAMC (WJ-MSCs/HAMC) (n = 10/each group). Coccygeal discs were removed following sacrifice 6 weeks after implantation for radiologic and histologic analysis. We confirmed previous findings that encapsulation in HAMC increases the viability of WJ-MSCs for disc repair. The HAMC gel maintained significant cell viability in vitro. In addition, combined implantation of WJ-MSCs and HAMC significantly promoted degenerative disc repair compared to WJ-MSCs alone, presumably by improving nucleus pulposus cells viability and decreasing extracellular matrix degradation. Our results suggest that WJ-MSCs-loaded HAMC promotes IVD repair more effectively than cell injection alone and supports the potential clinical use of HAMC for cell delivery to arrest IVD degeneration or to promote IVD regeneration.

RESUMO

The COVID-19 pandemic currently expanded its roots to the 206 countries in the world. The morbidity and mortality are not only threat to humans but also its impact on economy is indirectly affecting us. The current review was done to find trend in various states of India. Data was collected from Ministry of Health and Family Welfare and descriptive analysis of the distribution of COVID-19 cases in different states of India. First case of COVID-19 was diagnosed in southernmost state Kerala and after that it has spread to all other states, but situations are more worsen in states with high international migration. Maharashtra is now the most affected state followed by Delhi. Among epidemic curve of all these states, Maharashtra has rapidly growing epidemic curve with highest slope, whereas Kerala has the lowest. When we compared the day wise cumulative case fatality rate, it was found that the case fatality rate of the states like Maharashtra, Madhya Pradesh & Rajasthan showed decrease in the case fatality rate over the period. Population density is also one of the key determinants of social interaction and thus the spread of disease specifically in communicable diseases. Government of India had taken many strong initiatives e.g. 40 days nation-wide lockdown, thermal screening at airport, announcement of relief packages for poor and quarantine of outsiders but still there are many missed opportunities like, early stoppage of international traffic, compulsory quarantine for all international travellers, better contact tracing, strong law and order and better preparedness plan.
