RESUMO
Background: Attitudes and impressions toward the tobacco industry and tobacco products among the general public are important determinants for curbing the menace of the tobacco epidemic. Accordingly, this study aimed to assess the knowledge and perceptions about the tobacco industry and tobacco products and analyze attitudes towards social denormalization (SD) of tobacco use and tobacco industry denormalization (TID) among the rural population of Bihar, India. Methods: This community-based cross-sectional survey was conducted on 421 adults aged 18 to 65 years who were selected using multistage systematic random sampling in a rural area of Bihar State in India from January to March 2022. Results were presented as proportions and the factors associated with support for TID and SD were identified using the chi-square test and binary logistic regression. Findings: Out of 421 participants, 342 (81.2%) did not consider smokeless tobacco to be very dangerous. Nearly half (192, 45.6%) of the individuals believed that tobacco companies never tell the truth about the ill effects of tobacco use on health. Maximum, 345 (89.5%) also believed that the tobacco industry is responsible for adverse health effects of tobacco use and that the government should sue them. The prevalence of favorable attitudes toward TID and SD was found to be 55.1% [95% CI: 50.3% - 59.8%] and 38.2% [95% CI: 33.7% - 42.9%], respectively. Conclusion: One out of every two and one out of every three individuals showed favorable attitudes toward TID and SD, respectively. There is a need to inform and educate the public on the ill effects of tobacco and the deceptive strategies used by the tobacco industry to help them choose health over tobacco.
RESUMO
Background: Spinocerebellar ataxia (SCA) denotes an expanding list of autosomal dominant cerebellar ataxias. Although tremor is an important aspect of the clinical spectrum of the SCAs, its prevalence, phenomenology, and pathophysiology are unknown. Objectives: This review aims to describe the various types of tremors seen in the different SCAs, with a discussion on the pathophysiology of the tremors, and the possible treatment modalities. Methods: The authors conducted a literature search on PubMed using search terms including tremor and the various SCAs. Relevant articles were included in the review after excluding duplicate publications. Results: While action (postural and intention) tremors are most frequently associated with SCA, rest and other rare tremors have also been documented. The prevalence and types of tremors vary among the different SCAs. SCA12, common in certain ethnic populations, presents a unique situation, where the tremor is typically the principal manifestation. Clinical manifestations of SCAs may be confused with essential tremor or Parkinson's disease. The pathophysiology of tremors in SCAs predominantly involves the cerebellum and its networks, especially the cerebello-thalamo-cortical circuit. Additionally, connections with the basal ganglia, and striatal dopaminergic dysfunction may have a role. Medical management of tremor is usually guided by the phenomenology and associated clinical features. Deep brain stimulation surgery may be helpful in treatment-resistant tremors. Conclusions: Tremor is an elemental component of SCAs, with diverse phenomenology, and emphasizes the role of the cerebellum in tremor. Further studies will be useful to delineate the clinical, pathophysiological, and therapeutic aspects of tremor in SCAs.

Mitochondria play an important and multifaceted role in cellular function, catering to the cell's energy and biosynthetic requirements. They modulate apoptosis while responding to diverse extracellular and intracellular stresses including reactive oxygen species (ROS), nutrient and oxygen scarcity, endoplasmic reticulum stress, and signaling via surface death receptors. Integral components of mitochondria, such as mitochondrial DNA (mtDNA), mitochondrial RNA (mtRNA), Adenosine triphosphate (ATP), cardiolipin, and formyl peptides serve as major damage-associated molecular patterns (DAMPs). These molecules activate multiple innate immune pathways both in the cytosol [such as Retionoic Acid-Inducible Gene-1 (RIG-1) and Cyclic GMP-AMP Synthase (cGAS)] and on the cell surface [including Toll-like receptors (TLRs)]. This activation cascade leads to the release of various cytokines, chemokines, interferons, and other inflammatory molecules and oxidative species. The innate immune pathways further induce chronic inflammation in the tumor microenvironment which either promotes survival and proliferation or promotes epithelial to mesenchymal transition (EMT), metastasis and therapeutic resistance in the cancer cell's. Chronic activation of innate inflammatory pathways in tumors also drives immunosuppressive checkpoint expression in the cancer cells and boosts the influx of immune-suppressive populations like Myeloid-Derived Suppressor Cells (MDSCs) and Regulatory T cells (Tregs) in cancer. Thus, sensing of cellular stress by the mitochondria may lead to enhanced tumor growth. In addition to that, the tumor microenvironment also becomes a source of immunosuppressive cytokines. These cytokines exert a debilitating effect on the functioning of immune effector cells, and thus foster immune tolerance and facilitate immune evasion. Here we describe how alteration of the mitochondrial homeostasis and cellular stress drives innate inflammatory pathways in the tumor microenvironment.

In severe acute malnutrition, micronutrient deficiency as well as protein energy malnutrition is a major obstacle to growth & development. Iron deficiency dominates the spectrum of nutritional anemia. After taking informed consent, 211 SAM children and 211 age-and sex-matched healthy children with normal nutritional status were enrolled for the study. MUAC was used to diagnose SAM. A 5-part automated hematoanalyzer was used to measure the complete blood count and red cell indices, and the peripheral smear method to determine the red cell morphology. We measured serum ferritin, Vitamin B12, and folic acid using the ELISA method. Compared to controls, children with SAM had significantly lower red cell indices, platelet counts, and white cell counts. The most common clinical symptoms seen in SAM children were diarrhea, pneumonia, acute gastroenteritis, and acute respiratory infection. Children with SAM are more likely to suffer from iron deficiency and B12 deficiency. Severe vitamin B12 deficiency was more frequently associated with severe anemia. The severe anemia in SAM children constantly changes the body's defense mechanism, affecting the haematopoiesis. In this study, haematological indices are recommended for predicting severity of anemia, and hematopoietic changes are described, in order to improve anticipatory care and outcome in children with SAM.
RESUMO
This study discusses non-steady effects encountered in peristaltic flows in oesophagus. The purpose of this communication is to evolve a mechanism to diagnose tumor in an oesophagus mathematically. The tumor is modelled by generic bump function of certain height and width. The method of solution follows long wavelength and low-Reynolds number approximations for unsteady flow, while integrations have been performed numerically in order to plot graphs, which reveal various characteristics of the flow. The goal is to assess how pressure varies across the tumor's width. The spatial, as well as temporal, dependence of pressure has been studied in the laboratory frame of reference. The pressure distribution for tumor-infected oesophagus is compared with that of normal oesophagus. An intensified pressure is obtained in the presence of tumor. The interruption while swallowing through benign oesophageal tumor is confirmed by an abrupt pressure rise across the tumor's width. Tumor position also plays a significant role whether it is at contraction or relaxation of walls. Additionally, wall-shear-stress, volumetric flow rate and streamlines have also been described and compared with that without tumor growth. The expressions corresponding to all the physical quantities are computed numerically. Further, this model may also be implemented to the two-dimensional channel flow for an industrial application.

Inflammatory myofibroblastic tumors (IMTs) are rare spindle cell tumors clinically, morphologically, and genetically heterogeneous, mimicking many other reactive and neoplastic lesions and creating great diagnostic problems. Although it is generally characterized by oncogene-derived proliferation of myofibroblasts in a background of polyclonal inflammatory cell infiltrates, morphological variations do occur requiring immunohistochemistry and molecular genetics to confirm the diagnosis. It encompasses a wide age range, and locations, mostly said to be of intermediate grade having a low risk of recurrence and metastasis. However, its biological behavior and course are variable and unpredictable. Here, we report a case of thoracic IMT in a 32-year-old adult female presenting with a history of fever, cough, and chest pain associated with neutrophilic leukocytosis. Radiological investigations revealed a large mass in the thoracic region with possibilities of hydatid cyst and neurogenic tumor. Initial core needle biopsy specimen and subsequent local resection specimen revealed the diagnosis of IMT on histopathology and immunohistochemistry, having conventional morphology with expression of Anaplastic lymphoma kinase (ALK) protein. The patient developed rapid local recurrence and was started with first-generation ALK inhibitor Crizotinib. After a brief period of response, she developed vertebral and brain metastasis within a short span of time and was switched to a third-generation ALK inhibitor, Lorlatinib. The patient is on regular follow-up, has stable disease, and maintains a good quality of life after two years of diagnosis.
RESUMO
The Indian Punjab state is drained by the four rivers, along with a well-connected network of canals, and is now dealing with a slew of water quality issues and problems. In this study, basin-wise hydrogeochemical modelling of 323 groundwater samples and identification of NO3- and F- enrichment pathways in aquifer systems of Punjab were studied using different plots and multivariate statistics. To evaluate the groundwater quality and human health risks, an entropy-based water quality index and Monte Carlo simulation were used, respectively. Spatial distribution of NO3- indicated that its very high values were prominent in parts of southwestern Punjab falling under LSRB, along with few pockets in eastern and northeastern Punjab falling under MSRB and GRB. High NO3- values (> 45.0 mg/L) were found in 15.0% of Ravi River Basin (RRB) groundwater samples, 22.86% of Beas River Basin (BRB), 23.52% of Middle Sutlej River Basin (MSRB), 36.9% of Lower Sutlej River Basin (LSRB), and 21.31% of Ghaggar River Basin (GRB). The spatial distribution of NO3- revealed elevated concentrations (> 100 mg/L) in the southwestern part of Punjab, particularly in LSRB and localized pockets in the eastern and northeastern areas of Punjab within MSRB and GRB. High F- concentration (> 1.5 mg/L) was observed in 15.12% and 21.31% groundwater samples of LSRB and GRB, respectively. Spatially southern parts falling under LSRB and GRB reflected high F- content (> 1.5 mg/L) in groundwater. In LSRB, evaporative and anthropogenic processes influence the groundwater quality. The results of interionic relationships and statistical analysis revealed that NO3- has anthropogenic origin and that is being aggravated by leaching, the evaporation processes, animal excreta, septic tanks and irrigation return flows in LSRB and GRB, while F- is geogenic in nature. Hazard index (HI) values in 14.63%, 22.2%, 24.6%, 49.58%, and 34.42% samples for adults and 21.95%, 27.7%, 42.0%, 72.3%, and 52.46% samples for children were higher than unity in RRB, BRB, MSRB, LSRB, and GRB, respectively. The basin-wise demarcation of various groundwater quality parameter and assessment of human health risk would be of significance for the management of water resources.

BACKGROUND: The human immunodeficiency virus (HIV) causes movement disorders in persons living with HIV (PLH). OBJECTIVES AND METHODS: We conducted a systematic review on the spectrum of movement disorders in PLH using standard terms for each of the phenomenologies and HIV. RESULTS: Movement disorders in PLH were commonly attributed to opportunistic infections (OI), dopamine receptor blockade reactions, HIV-associated dementia (HAD), presented during seroconversion, developed due to drug reactions or antiretroviral therapy (ART) itself and lastly, movement disorders occurred as a consequence of the HIV-virus. Parkinsonism in ART naïve PLH was associated with shorter survival, however when Parkinsonism presented in PLH on ART, the syndrome was indistinguishable from Idiopathic Parkinson's disease and responded to therapy. Tremor was often postural due to HAD, drugs or OI. Generalized chorea was most frequent in HIV encephalopathy and toxoplasmosis gondii caused most cases of hemichorea. Ataxia was strongly associated with JCV infection, ART efavirenz toxicity or due to HIV itself. Dystonia was reported in HAD, secondary to drugs and atypical facial dystonias. Both cortical/subcortical and segmental/spinal origin myoclonus were noted mainly associated with HAD. In patients with HIV related opsoclonus-myoclonus-ataxia-syndrome, seroconversion illness was the commonest cause of followed by IRIS and CSF HIV viral escape phenomenon. CONCLUSIONS: Aetiology of movement disorders in PLH depend on the treatment state. Untreated, PLH are prone to develop OI and HAD and movement disorders. However, as the number of PLH on ART increase and survive longer, the frequency of ART and non-AIDS related complications are likely to increase.

BACKGROUND: Low back pain (LBP) is responsible for the highest number of years lived with disability globally. There is a paucity of data regarding the same among medical students. So, this study was planned to estimate the prevalence of acute LBP having a high propensity to develop into chronic one as well as to determine associated correlates among medical students. MATERIALS AND METHODS: This cross-sectional study was conducted among 300 medical students at a tertiary hospital using an Acute Low Back Pain Screening Questionnaire (ALBPSQ) to identify individuals with LBP and having a high risk of developing a long-term disability. ALBPSQ is a 21-question-based biopsychosocial screening instrument for identifying patients at risk of chronicity. ALBPSQ scores have been found to be significantly associated with pain and functional disability. Descriptive statistics, bivariate analysis, and multiple binary logistic regression have been performed through SPSS-22 software. RESULTS: The prevalence of LBP having the propensity to develop into a long-term disability was found to be 14.3% (95% CI: 10.6-18.8). In bivariate analysis, higher age, no exercise, higher screen time, mental stress, studying in bed, abnormal posture, alcohol intake, tobacco use, positive family history, greater screen time per day, and more time spent in a sitting posture are significant with LBP. Stress ((adjusted odds ratio) AOR: 4.37, 95% CI: 1.79-10.68)), abnormally bent standing posture (AOR: 3.6, 95% CI: 1.3-10.6), and positive family of LBP (AOR: 3.6, 95% CI: 1.3-10.1) were found to be independent predictors of LBP among medical students. CONCLUSION: Among medical students, every 15 out of 100 have a low back problem with chances of long-term disability. These students require early intervention to avoid long-term disability. Abnormal stooping posture, psychological stress, and positive family history of low pain might independently lead to LBP.
RESUMO
Background Of all the adolescents in India, 7.3% are suffering from some form of mental disorder. They frequently use tobacco to cope with these problems, but get stuck in a vicious cycle of deteriorating mental health. Our study aimed to determine the effect of tobacco on the mental health status of adolescents studying in the 9th to 12th standards in 10 high schools in urban and rural areas near Patna, Bihar. Methodology An analytical cross-sectional study was conducted among 360 school-going adolescents recruited using stratified random sampling. Selected adolescents were given the Indian Adolescent Health Questionnaire. The mental health status was calculated from the Strengths and Difficulties Questionnaire (SDQ) score. Information on sociodemographic characteristics and tobacco use was also obtained. Independent t-test, analysis of variance, and multiple linear regression analysis were used for predicting the significant factors. Significance was set at p-values <0.05. Results In this study, 40 (11.1%) adolescents had abnormal whereas 55 (15.3%) had borderline overall SDQ scores. The majority of those affected had peer problems (40%) and conduct problems (24.7%). All SDQ components of conduct (F = 2.94, p = 0.013), hyperactivity (F = 2.90, p = 0.014), emotional problems (F = 1.14, p = 0.001), and peer pressure (F = 3.06, p = 0.010), as well as the overall SDQ score (F = 5.74, p < 0.001), were significantly associated with increasing age. The adolescents attending rural schools (13.28 ± 5.22, p = 0.047) had significantly higher SDQ scores than those attending urban schools (12.08 ± 5.60). Hyperactivity scores were significantly higher in those studying in class 10 compared to other classes and in those attending rural rather than urban schools. Emotional problems score was significantly higher in 16-17-year-old students than in 14-15-year-old students, in females than in males, and in class 10 than in class 9 students. Only 24 (6.7%) adolescents had a history of tobacco consumption at least once which was significantly associated with the SDQ score (17.71 ± 5.69; t = 4.95, df = 358, p < 0.001). Around 79.4% of adolescents were exposed to passive smoking from close friends which deteriorated their overall mental health status (14.50 ± 5.99; F = 6.29, df = 2,357, p = 0.002). Those who had smoked for more than 10 days had significantly greater conduct problems and lesser pro-social behavior. Overall, 96.1% agreed that tobacco is harmful to health, and 76.1% had seen anti-smoking messages in the media. Female gender, increasing class and age, and history of smoking or chewing tobacco at least once also led to a significant increase in emotional problems. Age, area of the school, history of tobacco consumption, and exposure to cigarette smoke by either a close friend or male guardian had a significant impact on the conduct, hyperactivity, peer problems, and overall mental health status of school-going adolescents. Conclusions Predicting risk factors such as age, area of the school, and the history of tobacco consumption by self or by close friends is important for decision-making by school administration regarding counseling for mental health and preventing tobacco use.
RESUMO
INTRODUCTION AND HYPOTHESIS: Cystoscopy has been routinely performed in patients suspected to be suffering from bladder pain syndrome/interstitial cystitis (BPS/IC) across the globe. The methodology reported by various guidelines appears to have differences in the techniques and hence there is a need for a review of all those techniques in order to arrive at a consensus. The aim was to review the literature describing the prevalent techniques of cystoscopy for patients of BPS/IC and try to evolve a consensus. METHODS: The group the Global Interstitial Cystitis, Bladder Pain Society (GIBS) has worked collectively to systematically review the literature using the key words, "Cystoscopy in Hunner's lesions, bladder pain syndrome, painful bladder syndrome and interstitial cystitis" in the PubMed, COCHRANE, and SCOPUS databases. A total of 3,857 abstracts were studied and 96 articles referring to some part of technique of cystoscopy were short-listed for review as full-length articles. Finally, six articles with a description of a technique of cystoscopy were included for final tabulation and comparison. The group went on to arrive at a consensus for a stepwise technique of diagnostic and therapeutic cystoscopy in cases of BPS/IC. This technique has been compared with the previously described techniques and may serve to be a useful practical guide for treating physicians. CONCLUSION: It is important to have a uniform standardized technique for performing a diagnostic and therapeutic cystoscopy in patients with BPS/IC. Consensus on one such a technique has been arrived at and described in the present article.

Background: Mutations in the SF3B1 splicing factor are commonly seen in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), yet the specific oncogenic pathways activated by mis-splicing have not been fully elucidated. Inflammatory immune pathways have been shown to play roles in the pathogenesis of MDS, though the exact mechanisms of their activation in splicing mutant cases are not well understood. Methods: RNA-seq data from SF3B1 mutant samples was analyzed and functional roles of interleukin-1 receptor-associated kinase 4 (IRAK4) isoforms were determined. Efficacy of IRAK4 inhibition was evaluated in preclinical models of MDS/AML. Results: RNA-seq splicing analysis of SF3B1 mutant MDS samples revealed retention of full-length exon 6 of IRAK4, a critical downstream mediator that links the Myddosome to inflammatory NF-kB activation. Exon 6 retention leads to a longer isoform, encoding a protein (IRAK4-long) that contains the entire death domain and kinase domain, leading to maximal activation of NF-kB. Cells with wild-type SF3B1 contain smaller IRAK4 isoforms that are targeted for proteasomal degradation. Expression of IRAK4-long in SF3B1 mutant cells induces TRAF6 activation leading to K63-linked ubiquitination of CDK2, associated with a block in hematopoietic differentiation. Inhibition of IRAK4 with CA-4948, leads to reduction in NF-kB activation, inflammatory cytokine production, enhanced myeloid differentiation in vitro and reduced leukemic growth in xenograft models. Conclusions: SF3B1 mutation leads to expression of a therapeutically targetable, longer, oncogenic IRAK4 isoform in AML/MDS models.

Genes contain blocks of code that tell cells how to make each part of a protein. Between these blocks are sections of linking DNA, which cells remove when they are preparing to use their genes. Scientists call this process 'splicing'. Cells can splice some genes in more than one way, allowing them to make different proteins from the same genetic code. Mutations that affect the splicing process can change the way cells make their proteins, leading to disease. For example, the myelodysplastic syndromes are a group of blood cancers often caused by mutations in splicing proteins, such as SF3B1. The disorder stops blood cells from maturing and causes abnormal inflammation. So far, the link between splicing, blood cell immaturity, inflammation and cancer is not clear. To find out more, Choudhary, Pellagatti et al. looked at the spliced genetic code from people with myelodysplastic syndromes. Mutations in the splicing protein SF3B1 changed the way cells spliced an important signalling molecule known as IRAK4. Affected cells cut out less genetic code and made a longer version of this signalling protein, named IRAK4-Long. This altered protein activated inflammation and stopped blood cells from maturing. Blocking IRAK4-Long reversed the effects. It also reduced tumour formation in mice carrying affected human cells. The molecule used to block IRAK4, CA-4948 also known as Emavusertib is currently being evaluated in clinical trials for myelodysplastic syndromes and other types of blood cancer. The work of Choudhary, Pellagatti et al. could help scientists to design genetic tests to predict which patients might benefit from this treatment.

Background: Holmes' tremor (HT) is a low-frequency tremor characterized by a combination of rest, posture, and action components. We are reporting the clinical features, neuroimaging findings, and levodopa responsiveness in 12 patients with HT. Cases: The majority of the patients were male (11/12). Dystonia was observed in 10 patients and the remaining two patients had head tremor, a "forme-fruste" of cervical dystonia. The underlying etiologies were vascular (n = 8), head trauma (n = 2), and tumor resection (n = 2). Neuroimaging showed isolated involvement of the midbrain in four, thalamus in two, and basal ganglia and cerebellum in one patient each. A combination of the lesion (thalamus and cerebellum = 2; cerebellopontine angle = 1, and cortical/subcortical = 1) was present in four patients. Levodopa responsiveness was seen in 75% of patients including one with levodopa-induced dyskinesia. Literature Review: Of 139 patients from 49 studies, levodopa was tried in 123 patients. Improvement with levodopa was seen in 71 patients (57.72%). No improvement with levodopa was observed in 33 patients (26.82%) and details regarding therapeutic response were unavailable in 19 patients (15.44%). Conclusions: Dystonia is an important clinical manifestation of HT. Levodopa responsiveness seen in the majority of the patients is consistent with the hypothesis that nigrostriatal pathway damage is crucial for the pathophysiology of HT.
RESUMO
INTRODUCTION: After spinal cord injury, further neurological deterioration up to one to two neurological levels is not uncommon. Late neurological deterioration can occur after two months, mainly due to the syrinx formation. In a rare case like in sub-acute post-traumatic ascending myelopathy, the neurological level may ascend more than four levels from the initial level of injury and it usually starts within a few weeks after injury. CASE PRESENTATION: Our case was diagnosed as a case of traumatic spinal cord injury having a lower thoracic neurological level of injury initially, which rapidly progressed over a few weeks into a higher thoracic neurological level. He was operated with pedicle screw fixation of the spine before admission to rehabilitation unit. He was having progressive ascending neurological deterioration, starting a few days after surgery, which was evident by the progression of neurological level by more than four segments clinically. Cerebrospinal fluid(CSF) study showed no significant abnormality. Magnetic resonance imaging (MRI) study showed involvement of the spinal cord at the upper thoracic region. Patient was monitored to note any further worsening. Rehabilitation and supportive measures were provided according to standard protocol. DISCUSSION: Very few cases of ascending paralysis of more than four levels have been reported globally. It results in increased morbidity and mortality in spinal cord injury patients. In our case few possible reasons are ruled out but the actual underlying reason was not clear. Various hypotheses have been proposed as the cause in previous published literatures. Management is mostly supportive.

Background: The emergence of the COVID-19 pandemic and lockdown measures to confine it has disrupted the routine of the public. The impact of such long-term confinements on the lifestyle and diet of students are not known and hence this study was designed to assess the impact of lockdown due to the COVID-19 pandemic on the lifestyle and diet of university students. Methods: An online cross-sectional survey among 622 university students across various educational institutes of east India using a pre-designed questionnaire about lifestyle-diet before and during the lockdown. Results were tabulated and statistical tests like Paired t-test, Wilcoxon Rank sign test, and Mc-Nemar tests were applied and overall significance was attributed to P<0.05. Results: During the lockdown a total of 2.4% (95% CI: 1.4-3.8%) decrease in prevalence of tobacco use, 8.7% (95% CI: 6.6-11%) decrease in physical activity and a 0.8 hour (95% CI: 0.6-0.9 hour) increase in the mean sleep duration was observed. There was a significant increase in use of fresh fruits consumption [Median(IQR)-before:2(1-5);during:3(1-5) days] and a decrease in meat-poultry[Median(IQR)-before: 2(0-3);during: 1(0-3)days] and junk food[Median(IQR)-before:1(0-2);during:0(0-2)days] consumption during the lockdown. Conclusion: A significant proportion of changes in lifestyle and frequency of consumption of certain food items in the dietary pattern during the lockdown.
RESUMO
Introduction: Cancer bioenergetics is an essential hallmark of neoplastic transformation. Warburg postulated that mitochondrial OXPHOS is impaired in cancer cells, leading to aerobic glycolysis as the primary metabolic pathway. However, mitochondrial function is altered but not entirely compromised in most malignancies, and that mitochondrial uncoupling is known to increase the carcinogenic potential and modifies treatment response by altering metabolic reprogramming. Our earlier study showed that transient DNP exposure increases glycolysis in human glioma cells (BMG-1). The current study investigated the persistent effect of DNP on the energy metabolism of BMG-1 cells and its influence on tumor progression in glioma xenografts. Methods: BMG-1 cells were treated with 2,4-dinitrophenol (DNP) in-vitro, to establish the OXPHOS-modified (OPM-BMG) cells. Further cellular metabolic characterization was carried out in both in-vitro cellular model and in-vivo tumor xenografts to dissect the role of metabolic adaptation in these cells and compared them with their parental phenotype. Results and Discussion: Chronic exposure to DNP in BMG-1 cells resulted in dual-state hyper-energy metabolism with elevated glycolysis++ and OXPHOS++ compared to parental BMG-1 cells with low glycolysis+ and OXPHOS+. Tumor xenograft of OPM-BMG cells showed relatively increased tumor-forming potential and accelerated tumor growth in nude mice. Moreover, compared to BMG-1, OPM-BMG tumor-derived cells also showed enhanced migration and invasion potential. Although mitochondrial uncouplers are proposed as a valuable anti-cancer strategy; however, our findings reveal that prolonged exposure to uncouplers provides tumor growth advantage over the existing glioma phenotype that may lead to poor clinical outcomes.
RESUMO
INTRODUCTION: There is a risk of chronic hepatitis B virus (HBV)infection to the newborn through perinatal transmission from a hepatitis B surface antigen (HBsAg) positive mother that can later cause liver cirrhosis or hepatocellular carcinoma. This study was undertaken in a primary health center (PHC)in the Patna district to determine the prevalence of HBV among pregnant women and assess their knowledge across different characteristics. METHODOLOGY: A cross-sectional study was done among 275 pregnant women attending the PHC for the first time, using consecutive sampling. The study duration was 12 months. Socioeconomic, obstetric, risk history, and levels of knowledge about hepatitis B were collected followed by rapid diagnostic test (RDT)for serum HBsAg. Univariate analysis was used to compare the knowledge levels across different background characteristics. The significance was set at P < 0.05. RESULTS: Hepatitis B-positive pregnant women were 0.4%. Out of the 275 participants, only 43 had heard about hepatitis B. The mean knowledge score was 0.65 (±1.73) with 1.45% having adequate knowledge. The knowledge score was significant across education (P 0.040), category (P 0.022), hepatitis B immunization status (P 0.003), and risk factor (P 0.039). CONCLUSION: Knowledge was higher in the literate women belonging to the general category and higher social class, who received hepatitis B vaccination. However, the overall level of knowledge among the pregnant women was very poor, so they should be targeted for quality health education. Additionally, identifying the afflicted pregnant women through point-of-contact diagnosis will aid in community prevention of chronic hepatitis B.
RESUMO
BACKGROUND: Healthcare professionals (HCPs) have a definite role in tobacco control and can help immensely by setting examples. The current study aimed to study the tobacco use pattern and quitting behaviour among HCPs of India during the COVID-19 pandemic. METHODS: We addressed the research objective using a cross-sectional, anonymous online survey using 'google form" among 687 HCPs of India during December 2020. Descriptive and inferential statistics were performed using SPSS. RESULTS: Overall, 32.6% of the HCPs were ever tobacco user while 23.4% and 16.9% were current and daily tobacco user. During the COVID-19 pandemic, 51.7% and 43.1% of HCPs cut down the frequency and amount of tobacco use respectively while for 24.1% COVID-19 pandemic exerted no effect on their tobacco use. Presence of vulnerable population at home [ adjusted odds ratio (AOR): 17.5 (95% confidence interval (CI): 3.3-92.2)], ever tobacco quit attempt [AOR: 13.5 (95% CI:2.7-67.7)] and history of COVID-19 disease [AOR: 5.1 (95% CI:1.3-20.7)] significantly determined reduced tobacco use (60.3%) during the pandemic. Similarly, reduced tobacco use during the pandemic [AOR: 4.8 (95% CI:1.7-13.5)] and perception of both smoking and smokeless tobacco form to be harmful for COVID-19 [AOR: 4.8 (95% CI:1.7-13.5)] were the independent correlates of tobacco quit attempt (50.0%) during the pandemic. CONCLUSION: Tobacco use was quite rampant among the HCPs with every fourth and sixth being a current and daily tobacco user respectively. During the COVID-19 pandemic three in every five HCPs surveyed reduced tobacco use while every second HCP made a quit attempt.
RESUMO
BACKGROUND: Focal hand dystonia (FHD) is usually adult-onset focal dystonia that can be associated with marked occupational and functional disability leading to reduced quality of life. METHODS: Relevant studies on treatment options for FHD, their limitations, and current recommendations were reviewed using the PubMed search until March 31, 2021. Besides, the reference lists of the retrieved publications were manually searched to explore other relevant studies. RESULTS: and conclusion Currently, botulinum toxin has the best evidence for treatment of FHD, and 20-90% of patients experience symptomatic improvement. However, its benefit is often limited by the reduction of muscle tonus acting on the muscle spindle. Different surgical modalities that have been used to treat focal hand dystonia include lesional surgery, deep brain stimulation, and magnetic resonance-guided focused ultrasound thalamotomy. Recent studies exploring the role of behavioral techniques, sensorimotor training, and neuromodulation for the treatment of focal hand dystonia have reported good outcomes, but larger studies are required before implementing these interventions in practice.
