RESUMO

BACKGROUND: Circadian rhythm is characterised by daily variations in biological activity to align with the light and dark cycle. These diurnal variations, in turn, influence physiological functions such as blood pressure, temperature, and sleep-wake cycle. Though it is well established that the circadian pathway is linked to pro-inflammatory responses and circulating immune cells, its association with infectious diseases is widely unknown. OBJECTIVE: This comprehensive review aims to describe the association between circadian rhythm and host immune response to various kinds of infection. METHODS: We conducted a literature search in databases Pubmed/Medline and Science direct. Our paper includes a comprehensive analysis of findings from articles in English which was related to our hypothesis. FINDINGS: Molecular clocks determine circadian rhythm disruption in response to infection, influencing the host's response toward infection. Moreover, there is a complex interplay with intrinsic oscillators of pathogens and the influence of specific infectious processes on the CLOCK: BMAL1 pathway. Such mechanisms vary for bacterial and viral infections, both well studied in the literature. However, less is known about the association of parasitic infections and fungal pathogens with circadian rhythm modulation. CONCLUSION: It is shown that bidirectional relationships exist between circadian rhythm disruption and infectious process, which contains interplay between the host's and pathogens' circadian oscillator, immune response, and the influence of specific infectious. Further studies exploring the modulations of circadian rhythm and immunity can offer novel explanations of different susceptibilities to infection and can lead to therapeutic avenues in circadian immune modulation of infectious diseases.

RESUMO

Monkeypox is a global health issue caused by the monkeypox virus. It can spread from person to person through respiratory secretions, direct exposure to dermatological lesions of infected patients, or exposure to contaminated objects. It is more common in homosexual men, and most patients are asymptomatic. The gold standard for diagnosis is a real-time polymerase chain reaction. In the absence of testing facilities, clinicians rely upon detailed history to exclude other causes of fever with rashes. Initially, there is a prodrome phase of a few days, which is followed by the appearance of rashes. The dermatological manifestations are in the form of an exanthematous rash, which transforms through a macular, papular, and vesicular phase and disappears after crusting in approximately 3 weeks. There can be associated lymphadenopathy in these patients. Respiratory manifestations include nasal congestion and shortness of breath that may result in secondary bacterial infections. Additionally, patients can have neurological involvement in the form of encephalitis. Furthermore, ocular involvement can occur in the form of conjunctivitis, keratitis, and corneal ulceration. Other symptoms can include diarrhea, vomiting, myalgia, and backache. Since most patients do not require hospitalization, the approach to treatment is mainly vigilant monitoring, antiviral therapy, and management of associated complications.

RESUMO

Key Clinical Message: Posterior reversible encephalopathy syndrome may occur secondary to abrupt cessation of antihypertensive therapy. A gradual reduction in blood pressure and counseling regarding medication adherence are crucial to prevent adverse consequences. Abstract: Posterior reversible encephalopathy syndrome (PRES) is a reversible clinical radiographic syndrome with headache, hypertensive encephalopathy, seizures, and visual disturbances as common modes of presentation. PRES can be attributed to several risk factors. We reported the case of a 66-year-old Asian female with PRES following nonadherence to antihypertensive treatment. Initially, her computed tomography scan of the head was normal. After 48 h, we again ordered a head CT scan, which showed lesions suggestive of hypertensive encephalopathy. We immediately reduced 20%-25% of mean arterial pressure, followed by a gradual blood pressure lowering to avoid adverse consequences. We did a follow-up CT scan of the head at 2 weeks, showing the resolution of early lesions. Hence, we made a diagnosis of PRES. In these patients, it is crucial to ensure medication adherence to avoid complications.

RESUMO

Key Clinical Message: Filariasis may present as an isolated perinephric abscess. Hence, a high index of suspicion should be maintained in endemic settings. Abstract: In cases with unexplained fever, eosinophilia and perinephric collection, it is necessary to do detailed infectious disease work up. High index of suspicion is required to diagnose filariasis due to its wide range of clinical presentation and laboratory findings. It may present as perinephric abscess, which can be diagnosed through ultrasonography.

RESUMO

Objectives: This study aimed to determine self-medication prevalence and its associated factors. Methods: A community-based cross-sectional study was conducted in the urban and rural catchment areas of Uttar Pradesh, India, among 440 adults using a pretested, semistructured questionnaire. The Chi-square test and logistic regression were used to determine the association of self-medication prevalence with various independent variables. The associations were reported as adjusted odds ratios and 95% confidence intervals. Results: The prevalence of medication use was 66.4%. The majority of participants (45%) took medicine for fever, cough (40.1%), and cold (31.8%). Allopathy (83.2%) was the most common medicine system used for self-medication. More than half reported taking medicine such as paracetamol (52%), followed by cough syrup (21%) and antihistaminic (17%). Convenience (46%) and lack of time (35.3%) were commonly cited reasons for self-medication. Also, 64.4% of the respondents practiced self-medication on the pharmacist's recommendation. Urban participants (adjusted odds ratio: 9.85, 95% confidence interval: 5.32-18.23), females (adjusted odds ratio: 2.32, 95% confidence interval: 1.18-4.57), skilled workers (adjusted odds ratio: 5.62, 95% confidence interval: 1.80-17.5), and those who completed primary school (adjusted odds ratio: 2.48, 95% confidence interval: 1.16-5.25) were more likely to self-medicate than rural, male, unemployed, and illiterate participants, respectively. Also, participants whose income was 30,000 Indian rupees (adjusted odds ratio: 3.21, 95% confidence interval: 1.00-10.21) were more likely to self-medicate than those whose income was less than 4000. Conclusions: A high prevalence of self-medication was found, particularly in urban areas. Convenience and lack of time were commonly cited reasons for self-medication. Allopathy was the most widely used medicine system for self-medication. Antipyretics, cough syrups, and antiallergics were most commonly self-medicated. Gender, education, and income were associated with self-medication. The study highlighted the increased usage among females which could be further explored and role of pharmacists' recommendation as a major driver for self-medication.

RESUMO

Background: Noma is a neglected tropical disease and a global health concern. Objectives: To elucidate the epidemiology, management, prevention, and public health implications of Noma. Methods: PubMed, Scopus, and Web of Science, supplemented by Google Scholar and World Health Organization databases, were searched using keywords to gather both published and grey literature from 1970 to 2023 in English. Results: Approximately 30,000-40,000 cases occur annually, with varying incidences across various African countries, such as Nigeria, Niger, and Chad. Incidence in Nigerian and Ethiopian states range from 0.6 to 3300 and 1.64 to 13.4 per 100,000 population, respectively. Mortality is approximately 8.5% in Niger. Risk factors include malnutrition, immunocompromised status, poor dental hygiene, inadequate sanitation, gingival lesions, low socioeconomic status, chronic and infectious diseases, low birth weight, high parity, diarrhoea, and fever. Diagnosis is primarily made based on clinical signs/symptoms and accordingly staging of disease is done. Stage I, II and II presents with acute necrotizing gingivitis, facial edema with halitosis, and necrotizing stomatitis, respectively. If the patient survives acute stages, the progress to Stage IV and Stage V manifests as trismus, difficulty in deglutition and phonation, and facial disfigurement, with increased severity in last stage. Treatment encompasses antibiotic therapy (amoxicillin, metronidazole, chlorhexidine, ampicillin, gentamicin), surgical interventions, wound management (honey dressing, ketamine), and nutritional support. Prevention strategies include oral hygiene, vaccination, health education, and community-based interventions. Conclusion: Noma's recent inclusion in WHO list of neglected tropical diseases is a milestone in recognizing the importance of prevention and early intervention to globally enhance health outcomes.

RESUMO

Nigeria's neurosurgical field faces profound challenges, including a critically low neurosurgeon-to-patient ratio and significant migration of medical professionals to developed countries. High costs, low socioeconomic status, and the urban-centric location of neurosurgical centers impede access to care. Key barriers to service delivery include lack of manpower, insufficient emergency care, limited imaging modalities, inadequate operative equipment, and ineffective political and administrative policies. Neurotrauma is the primary reason for neurosurgical intervention but is poorly managed due to delayed access and insufficient guidelines. The neurosurgical education system is strained by limited training capacity and the absence of subspecializations, restricting specialized care. Research output is low, hindered by limited infrastructure, lack of databases, insufficient funding, and minimal international collaboration. To address these issues, it is critical to enhance the imaging capabilities, ensure the availability of operative equipment, and establish effective policies for task sharing and communication at different levels of care. Other approaches include expanding training capacity, particularly in rural areas, implementing a uniform match system for residency, addressing gender disparities, and utilizing dual practice to ensure adequate compensation for neurosurgeons. Furthermore, stakeholders should develop subspecialization programs in areas such as neurovascular, neuro-oncology, pediatric neurosurgery, and minimally invasive neurosurgery to expand service scope. To transform the neurosurgical research landscape, efforts should be made to establish electronic medical databases, foster international collaborations to ensure funding, and make research mandatory for accreditation renewal to ensure continuous academic contribution.

RESUMO

BACKGROUND: Traumatic spinal cord injury (TSCI) is a debilitating neurological condition with significant long-term consequences on the mental health and well-being of affected individuals. We aimed to investigate anxiety and depression in individuals with pediatric-onset TSCI. METHODS: PubMed, Scopus, and Web of Science databases were searched from inception to December 20th, 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, and studies were included according to the eligibility criteria. RESULTS: A total of 1013 articles were screened, and 18 studies with 4234 individuals were included in the final review. Of these, 1613 individuals (38.1%) had paraplegia, whereas 1658 (39.2%) had tetraplegia. A total of 1831 participants (43.2%) had complete TSCI, whereas 1024 (24.2%) had incomplete TSCI. The most common etiology of TSCI with 1545 people (36.5%) was motor vehicle accidents. The youngest mean age at the time of injury was 5.92 ± 4.92 years, whereas the oldest was 14.6 ± 2.8 years. Patient Health Questionnaire-9 was the most common psychological assessment used in 9 studies (50.0%). Various risk factors, including pain in 4 studies (22.2%), reduced sleep quality, reduced functional independence, illicit drug use, incomplete injury, hospitalization, reduced quality of life, and duration of injury in 2 (11.1%) studies, each, were associated with elevated anxiety and depression. CONCLUSIONS: Different biopsychosocial risk factors contribute to elevated rates of anxiety and depression among individuals with pediatric-onset TSCI. Individuals at risk of developing anxiety and depression should be identified, and targeted support should be provided. Future large-scale studies with long-term follow-up are required to validate and extend these findings.

RESUMO

Chronic subdural hematomas are typically observed in elderly patients receiving antithrombotic and/or anticoagulant therapy. In contrast, acute subdural and extradural hematomas are often observed in young people with traumatic brain injury. The coexistence of ipsilateral chronic subdural and extradural hematomas is rare. Depending on the Glasgow Coma Scale and neuroimaging findings, early surgical intervention is mandatory, as seen in our patient. Early surgical evacuation of a traumatic extradural and chronic subdural hematoma should be done. Also, antithrombotic drug use can lead to chronic subdural hematoma.

RESUMO

Key Clinical Message: In non-healing ulcers with a previous history of burns, clinicians should have a high index of suspicion for Marjolin's ulcer and a low threshold for biopsy, irrespective of age. Abstract: Marjolin's ulcer is a rare malignancy arising from chronic inflammation and commonly manifests in burn scars. Thus, in cases of chronic wounds or non-healing ulcers, health professionals should have a high index of suspicion and a low threshold for biopsy, irrespective of age. Early diagnosis and timely management of tumors can improve the prognosis and overall survival rate. Moreover, further studies are needed to develop an evidence-based management approach for Marjolin's ulcer.

RESUMO

Assessing health-related quality of life (HRQoL) and its associated factors is essential for providing adequate healthcare and developing necessary interventions in women postdelivery. This study intended to find out the HRQoL score and related factors among women postdelivery in Nepal. Methodology: This was a cross-sectional study using nonprobability sampling conducted at a Maternal and Child Health (MCH) Clinic in Nepal. The study participants were 129 women postdelivery to 12 months who visited the MCH Clinic from 2 September 2018 to 28 September 2018. Outcome measures were sociodemographic, clinical indicators, obstetric indicators, and their relation with the overall HRQoL score of postdelivery mothers using the Short Form Health Survey (SF-36) Version 1. Results: Of 129 respondents, 68.22% were in the 21-30 age group, 36.43% were upper caste, 88.37% were Hindu, 87.60% were literate, 81.39% were homemakers, 53.49% with income less than 12 months, 88.37% had family support, and 50.39% with vaginal deliveries. HRQoL was significantly more in employed women (P=0.037), those with family support (P=0.003), and those who had a cesarean section (P=0.02) and wanted pregnancy (P=0.040). Conclusion: HRQoL in women postdelivery can be influenced by employment status, family support, type of delivery, and desirability of pregnancy.

RESUMO

Epitopes are the cornerstones for the development of rational vaccine design strategies. Conventionally, epitopes are used by chemical conjugation with the carrier protein. This chapter describes our computational epitope grafting methodology to identify the preferential grafting site in a carrier protein/scaffold. We have used the mota epitope as an example, as it was already experimentally validated by an independent group. In this chapter, we have provided sufficient details to enable the wet experimentalist to employ this computational methodology in their research objective. Scripts/programs are extensively described in this chapter and freely accessible through the provided link.

RESUMO

Objectives: This study aims to assess health science students' knowledge and attitude about COVID-19 epidemiology, management, and prevention; and the association of knowledge and attitude with various sociodemographic characteristics. Methods: An online survey was done among 524 undergraduate health science students using a pre-tested questionnaire across 19 health science institutions in Nepal from 30 June to 11 August 2021. All subjects were enrolled in the study after informed consent. Outcomes were Knowledge level, attitude level, and predictors of knowledge level and attitude level. Bivariate analysis was done to determine the association between variables. Results: Of 524 students, 42.9% were male, and 57.1% were female. More than half (54.6%) and the majority (85.1%) participants had good knowledge and attitude, respectively. Approximately three-fifths (59.4%) of the participants were from the B. P. Koirala Institute of Health Sciences (BPKIHS). Students in BPKIHS (odds ratio = 1.774; 95% confidence interval = 1.243-2.533), junior years (odds ratio = 8.892; 95% confidence interval = 5.814-13.599), age less than 23 years (odds ratio = 2.985; 95% confidence interval = 2.089-4.266) were more likely to have good knowledge. Students under 23 years (odds ratio = 24.160; 95% confidence interval: 9.570-60.992) and those in junior years (odds ratio = 4.460; 95% confidence interval = 3.753-5.300) were likely to have a good attitude level. Students in BPKIHS (odds ratio = 0.443; 95% confidence interval = 0.272-0.722) were less likely to have a good attitude. Conclusions: Overall, health science students had adequate knowledge and a good attitude regarding COVID-19. However, students lacked knowledge regarding infectiousness, transmission, post-vaccination observation period, remdesivir use, convalescent plasma therapy, and awake-prone positioning. Knowledge and attitude scores were associated with age, stream, and study institution.

RESUMO

Inhalation of crystalline silica-rich dust particles can result in the deadly occupational lung disorder called silicosis. The risk of contracting tuberculosis (TB) and the potential for lung cancer increase due to silicosis. This review article aims to bring to light the state of silicosis and TB scenario in the world and India for evaluating hurdles in the present and future to achieve the elimination road map and assess these conditions in the backdrop of the COVID-19 pandemic. A patient with silicosis has a 2.8-2.9 times higher risk of developing pulmonary TB and 3.7 times that of extrapulmonary TB. Incidences of missed cases when TB was misdiagnosed with silicosis due to indifferent clinical manifestations of the two in the initial stages are not uncommon. The duration of silica exposure and silicosis severity are directly related to the propensity to develop TB. As per a study, an average gap of 7.6 years has been noticed in a South African population for silico-tuberculosis to develop post-silicosis. In a study done on mine workers at Jodhpur, Rajasthan, it was seen that there is no definitive relation between patients with silicosis and the possibility of having COVID-19. There is a significant need to integrate the Silicosis control program with the TB elimination program for the government. A few steps can include assessing the workplaces, periodic monitoring of the workers' health, active case surveillance, identification of hotspots, and introducing reforms to curb the spread of dust and particulate matter from industrialised areas be taken in this regard.
