RESUMO

BACKGROUND: The pandemic has put at risk the social and emotional development of children on account of the paucity of arenas for social interaction. This study from Kerala, India was conducted to assess the resilience factors, behavioural concerns, psychological distress symptoms among the children aged 3 to 5 years. We also tried to look into the lost opportunities that could have aided the social and emotional development of children like peer interaction, child care hours. METHODS: The cross-sectional study was conducted among the children aged 3 to 5 years. A total of 535 children attending the immunisation clinics were enrolled by consecutive sampling. Devereux Early Childhood Assessment P2 (DECA P2) questionnaire was used to assess the levels of resilient factors and behavioural concerns in the study population. RESULTS: We observed a high proportion of children in the area of need category of protective factors under DECA P2. The proportion of children falling under area of concern was 64.5%, 49%, 68.4% for attachment/relationship, self-regulation, and initiative respectively. 24.9% study subjects have a behavioural concern score that puts them in the area of need category. The logistic regression model we created identified 'Male Gender,' 'Mothers could spend only less time for child care' and 'electronic devices used as pacifier' as significant predictors for belonging to Area of need Behavioural Concerns T score category. CONCLUSION: A large proportion of children aged between 3 to 5 years with reported behavioural concerns and lack of protective factors for socioemotional development. This can be attributed partly to the ongoing pandemic and its associated restrictions. The increased child care hours invested by parents or grandparents could have sized down the full impact that the pandemic would have had on the socio emotional development of the child. Increased time spent using electronic devices coupled with dwindled opportunities for interaction with peers have been notable challenges.

RESUMO

Network dynamical systems with higher-order interactions are a current trending topic, pervasive in many applied fields. However, our focus in this work is neurodynamics. We numerically study the dynamics of the smallest higher-order network of neurons arranged in a ring-star topology. The dynamics of each node in this network is governed by the Chialvo neuron map, and they interact via linear diffusive couplings. This model is perceived to imitate the nonlinear dynamical properties exhibited by a realistic nervous system where the neurons transfer information through multi-body interactions. We deploy the higher-order coupling strength as the primary bifurcation parameter. We start by analyzing our model using standard tools from dynamical systems theory: fixed point analysis, Jacobian matrix, and bifurcation patterns. We observe the coexistence of disparate chaotic attractors. We also observe an interesting route to chaos from a fixed point via period-doubling and the appearance of cyclic quasiperiodic closed invariant curves. Furthermore, we numerically observe the existence of codimension-1 bifurcation points: saddle-node, period-doubling, and Neimark-Sacker. We also qualitatively study the typical phase portraits of the system, and numerically quantify chaos and complexity using the 0-1 test and sample entropy measure, respectively. Finally, we study the synchronization behavior among the neurons using the cross correlation coefficient and the Kuramoto order parameter. We conjecture that unfolding these patterns and behaviors of the network model will help us identify different states of the nervous system, further aiding us in dealing with various neural diseases and nervous disorders.

RESUMO

Centrosomes, the main microtubule organizing centers (MTOCs) of metazoan cells, contain an older "mother" and a younger "daughter" centriole. Stem cells either inherit the mother or daughter-centriole-containing centrosome, providing a possible mechanism for biased delivery of cell fate determinants. However, the mechanisms regulating centrosome asymmetry and biased centrosome segregation are unclear. Using 3D-structured illumination microscopy (3D-SIM) and live-cell imaging, we show in fly neural stem cells (neuroblasts) that the mitotic kinase Polo and its centriolar protein substrate Centrobin (Cnb) accumulate on the daughter centriole during mitosis, thereby generating molecularly distinct mother and daughter centrioles before interphase. Cnb's asymmetric localization, potentially involving a direct relocalization mechanism, is regulated by Polo-mediated phosphorylation, whereas Polo's daughter centriole enrichment requires both Wdr62 and Cnb. Based on optogenetic protein mislocalization experiments, we propose that the establishment of centriole asymmetry in mitosis primes biased interphase MTOC activity, necessary for correct spindle orientation.

RESUMO

Restoring homeostasis following proteostatic stress hinges on a stress-specific transcriptional signature. How these signatures are regulated is unknown. We use functional genomics to uncover how activating transcription factor 6 (ATF6), a central factor in the unfolded protein response, regulates its target genes in response to toxicant induced and physiological stress in the liver. We identified 652 conserved putative ATF6 targets (CPATs), which functioned in metabolism, development and proteostasis. Strikingly, Atf6 activation in the zebrafish liver by transgenic nAtf6 overexpression, ethanol and arsenic exposure resulted in a distinct CPAT signature for each; with only 34 CPATs differentially expressed in all conditions. In contrast, during liver regeneration in mice resulted in a dynamic differential expression pattern of 53% of CPATs. These CPATs were distinguished by residing in open chromatin, H3K4me3 occupancy and the absence of H3K27me3 on their promoters. This suggests that a permissive epigenetic landscape allows stress-specific Atf6 target gene expression.

RESUMO

OBJECTIVES: Sulfasalazine has been widely used in treatment of rheumatoid arthritis and spondyloarthritis. This study aims to assess persistence with sulfasalazine and also frequency and severity of adverse drug reactions (ADRs) encountered with this very well-established disease-modifying anti-rheumatoid drug. MATERIALS AND METHODS: This retrospective study was done in 1,114 patients from medicine and rheumatology outpatient departments of six centers across India. The inclusion criteria was patients taking sulfasalazine. Patients receiving sulfasalazine for rheumatoid arthritis or spondyloarthritis were selected and details on drugs used, duration of taking sulfasalazine, ADRs to sulfasalazine and whether sulfasalazine had to be stopped due to ADRs were analyzed. RESULTS: Of the total of patients included in the study, 10.1% had ADRs with sulfasalazine, and stopped the drug. Gastritis, deranged liver enzymes, hepatitis, skin rashes were the most commonly encountered ADRs. Of the total number of patients recruited for the study, 11% were lost to follow-up, as most of the centers were army hospitals and the officers and staff were posted to other places. Sulfasalazine was taken for less than 1 month by 3.8% patients while 12.5% had taken the drug for less than 6 months. Of the study patients, 28.6% had taken the drug for 24 - 60 months and 4.6% (51 patients) had taken it for more than 5 years. It was found that ADRs were most commonly encountered within the first year of using the drug, and persistence was seen in patients on long-term therapy. CONCLUSION: Sulfasalazine is a safe option in chronic therapy of rheumatoid arthritis and spondyloarthritis. Although frequency of ADRs with patients taking sulfasalazine is minimal, it did necessitate the stoppage of drug. If not well tolerated, sulfasalazine would not have been continued for more than 12 months as evidenced from this study.

RESUMO

Nanoscale imine-linked covalent organic frameworks (nCOFs) were first loaded with the anticancer drug Doxorubicin (Dox), coated with magnetic iron oxide nanoparticles (γ-Fe2O3 NPs), and stabilized with a shell of poly(l-lysine) cationic polymer (PLL) for simultaneous synergistic thermo-chemotherapy treatment and MRI imaging. The pH responsivity of the resulting nanoagents (γ-SD/PLL) allowed the release of the drug selectively within the acidic microenvironment of late endosomes and lysosomes of cancer cells (pH 5.4) and not in physiological conditions (pH 7.4). γ-SD/PLL could efficiently generate high heat (48 °C) upon exposure to an alternating magnetic field due to the nCOF porous structure that facilitates the heat conduction, making γ-SD/PLL excellent heat mediators in an aqueous solution. The drug-loaded magnetic nCOF composites were cytotoxic due to the synergistic toxicity of Dox and the effects of hyperthermia in vitro on glioblastoma U251-MG cells and in vivo on zebrafish embryos, but they were not significantly toxic to noncancerous cells (HEK293). To the best of our knowledge, this is the first report of multimodal MRI probe and chemo-thermotherapeutic magnetic nCOF composites.

RESUMO

Inorganic arsenic (iAs) is one of the most endemic toxicants worldwide and oxidative stress is a key cellular pathway underlying iAs toxicity. Other cellular stress response pathways, such as the unfolded protein response (UPR), are also impacted by iAs exposure, however it is not known how these pathways intersect to cause disease. We optimized the use of zebrafish larvae to identify the relationship between these cellular stress response pathways and arsenic toxicity. We found that the window of iAs susceptibility during zebrafish development corresponds with the development of the liver, and that even a 24-h exposure can cause lethality if administered to mature larvae, but not to early embryos. Acute exposure of larvae to iAs generates reactive oxygen species (ROS), an antioxidant response, endoplasmic reticulum (ER) stress and UPR activation in the liver. An in vivo assay using transgenic larvae expressing a GFP-tagged secreted glycoprotein in hepatocytes (Tg(fabp10a:Gc-EGFP)) revealed acute iAs exposure selectively decreased expression of Gc-EGFP, indicating that iAs impairs secretory protein folding in the liver. The transcriptional output of UPR activation is preceded by ROS production and activation of genes involved in the oxidative stress response. These studies implicate redox imbalance as the mechanism of iAs-induced ER stress and suggest that crosstalk between these pathways underlie iAs-induced hepatic toxicity.

RESUMO

Triphenylphosphine (TPP) surface-functionalized and F-108 Pluronic-stabilized gold nanoparticles (F-108@TPP-AuNPs) have been synthesized through a one-step approach, leading to well-defined (9.6±1.6 nm) and water-soluble nanoparticles by microwave heating an aqueous solution of TPP-AuI Cl in the presence of a Pluronic polymer under basic conditions. TPP release was negligible under physiological conditions, but enhanced significantly at an acidic pH (5.4) mimicking that of a cancer cell. Laser irradiation (532 nm) raised the temperature of an aqueous solution of F-108@TPP-AuNPs to 51.7 °C within 5 min, confirming efficient light-to-heat conversion capabilities without significant photodegradation. TEM confirmed intracellular localization of F-108@TPP-AuNPs in the cytosol, endosomes and lysosomes of HeLa cells. F-108@TPP-AuNPs were well tolerated by HeLa cells and zebrafish embryos at ambient temperatures and became toxic upon heat activation, suggesting synergistic interactions between heat and cytotoxic action by TPP.

RESUMO

AIM: This study was aimed to investigate the hemocompatibility of zirconia and titanium implant materials after surface treatment with sandblasting and acid etching (SLA). MATERIALS AND METHODS: Sixty specimens were procured from manufacturers of dimension 10mm × 3mm, thirty of each were prefabricated medical grade titanium (Ti-6Al-4V) and thirty of sintered zirconia. Silicon carbide grit papers of 240 to 1200pm, was used to polish the specimen surface. The surfaces were rinsed with water to remove any remnant particles after polishing. Later ultrasonic cleaning was done for 5 minutes using distilled water. The control specimens included 15 specimens each from titanium (groups A1) and zirconia (groups B1). The remaining 15 specimens (groups A2 and B2) were sandblasted using alumina particles of 150 microns particle size and using 20% hydrochloric acid, acid etching was done for 30 seconds. The specimens were scanned under electron microscope after surface treatment for analysis purpose and evaluated for surface characteristics. Before the exposure of specimens to blood, percentage hemolysis, prothrombin, platelet aggregation and activation, and thrombin time values were calculated. one mL of blood was added to each specimen for testing. The values before and after the exposure of specimens to blood were noted. Using a t-test, the values noted were statistically Results: A1 (polished titanium) showed highest mean values after exposure, in platelet count (184.67 ± 1.29), leucocyte count (7.27 ± 0.08), and thrombin time (10.15 ± 0.34) while prothrombin time's highest mean value after exposure were showed by A2 (SLA treated titanium) with a mean value of 10.04 ± 0.24. CONCLUSION: Surface treatment with sandblasting and acid etching (SLA) using 150 microns alumina particles and 20% hydrochloric acid increased the surface roughness of the titanium and zirconia implant materials and polished titanium showed maximum hemocompatibility. CLINICAL SIGNIFICANCE: The implant's success depends on its biocompatibility and its property of osseointegration. The adverse interaction between blood and the artificial surface is detected by the hemocompatibility test for medical materials, to know if the surface can activate or destruct the blood components. The success of implant placement also depends on the interaction between the blood and the specimen.

RESUMO

AIM: The current study emphasizes the impact of adverse drug reactions (ADRs) and Drug-Related Problems (DRPs) caused by supportive care medications administered with chemotherapy. METHOD: This is a longitudinal observational study carried out at the Ramaiah Medical College Hospital in Bengaluru, Karnataka, India, at the Department of Oncology. The data was recorded using a specifically created data collecting form. Based on the PCNE (Pharmaceutical Care Network Europe), DRPs are identified. The WHO probability scale, Modified Hartwig and Siegel for ADR severity assessment, Naranjo's algorithm for causality assessment, Rawlins and Thompson for predictability assessment, and Modified Shumock and Thornton for preventability assessment were all utilized. The OncPal guideline was considered in terms of the precision of supportive care medications regarding the reduction of ADRs in cancer patients. RESULT: We enrolled 302 patients,166 (55%) female and 136 (45%) male (SD 14.378) (mean 49.97), patients with one comorbidity 59(19.6%) and multimorbidity (two or more) 45(14.9%), the DRPs identified were found to be 153 (50.6%); only P2 (safeties of drug therapy PCNE) were considered in this study. ADRs which are identified 175(57.9%) contributed/caused by the supportive care medications. WHO probability scale: 97 (32.1%) possible and 60 (19.9%) unlikely; Naranjo's algorithm: 97 (32.1%) unlikely and 69 (22.8%) possible; ADR severity assessment scale (Modified Hartwig and Siegel): 95 (31.5%) mild and 63 (20.9%) moderates; Rawlins and Thompson for determining predictability of an ADR: 33 (10.9%) predictable and 137 (45.5%) non-predictable; and Modified Shumock and Thornton for determining preventability of an ADR: 81 (26.8%) probably preventable and 90 (29.8%) non-preventable. The statistical comparison through preforming t-test and measuring Chi-Square between group with ADRs and without ADRs shows in some variables, significantly (Alcohol consumption status, P = .019) and Easter Cooperative Oncology Group (ECOG) performance status P < 0.001. CONCLUSION: Comprehensive assessment of supportive medications in cancer patients would enhance the patient management and therapeutic outcome. The potential adverse drug reactions (ADRs) caused by supportive care medications can contribute to longer hospital stays and interact with the systemic anti-cancer treatment. The health care professionals should be informed to monitor the patients clinically administered with supportive medications.

RESUMO

The optical transparency of zebrafish larvae enables visualization of subcellular structures in intact organs, and these vertebrates are widely used to study lipid biology and liver disease. Lipid droplet (LD) presence is a prevalent feature of healthy cells but under conditions such as nutrient excess, toxicant exposure or metabolic imbalance, LD accumulation in hepatocytes can be a harbinger of more severe forms of liver disease. We undertook a comprehensive analysis of approaches useful to investigate LD distribution and dynamics in physiological and pathological conditions in the liver of zebrafish larvae. This comparative analysis of the lipid dyes oil red O (ORO), Nile Red (NR), LipidTox and LipidSpot as well as transgenic LD reporters that rely on EGFP fusions of the LD decorating protein perilipin 2 (PLIN2) demonstrate the strengths and limitations of each approach. These protocols are amenable to detection methods ranging from low resolution stereomicroscopy to confocal imaging, which enables measurements of hepatic LD size, number and dynamics at cellular resolution in live and fixed animals. This resource will benefit investigators studying LD biology in zebrafish disease models.

RESUMO

BACKGROUND: Migraine is a disabling primary headache disorder characterized by recurrent episodes of headache. Migraine not only imposes a burden on the sufferer but also imposes a burden on their family members too. A holistic approach is more essential in the management of migraine and family members should also be included in the management of migraine. There are no published studies done in India so far to look for the impact of migraine on partners and adolescent children (IMPAC). This pilot study was done to assess the IMPAC. OBJECTIVE: The objective of the study was to study the IMPAC. MATERIALS AND METHODS: In this descriptive study, 130 chronic migraine patients were observed in a row during 9 months. The impact of migraine on family members as well as migraine disability and Migraine-specific Quality of Life (MSQoL) was evaluated using validated questionnaires. RESULTS: One hundred and thirty chronic migraine patients were studied as part of this study. The mean age of the study population was 34.43 ± 9.002 years, and two-third of the participants were female. The majority of the participants had a moderate-to-severe disability due to migraine and had negatively impacted their MSQoL. The impact of migraine on family members was moderate-to-severe grade in most of the participants and affected their family life negatively both with children and spouses. The males were more significantly affected than females in terms of MSQoL, anxiety, depression, and also on migraine's impact on family members. CONCLUSION: Migraine not only affects the sufferers, it also significantly affects their family members.

RESUMO

Background Arterial compression of the trigeminal nerve at the root entry zone has been the long-attributed cause of compressive trigeminal neuralgia despite numerous studies reporting distal and/or venous compression. The impact of compression type on patient outcomes has not been fully elucidated. Objective We categorized vascular compression (VC) based on vessel and location of compression to correlate pain outcomes based on compression type. Methods A retrospective video review of 217 patients undergoing endoscopic microvascular decompression for trigeminal neuralgia categorizing VC into five distinct types, proximal arterial compression (VC1), proximal venous compression (VC2), distal arterial compression (VC3), distal venous compression (VC4), and no VC (VC5). VC type was correlated with postoperative pain outcomes at 1 month ( n = 179) and last follow-up (mean = 42.9 mo, n = 134). Results At 1 month and longest follow-up, respectively, pain was rated as "much improved" or "very much improved" in 89 69% of patients with VC1, 86.6 and 62.5% of patients with VC2, 100 and 87.5% of patients with VC3, 83 and 62.5% of patients with VC4, and 100 and 100% of patients with VC5. Multivariate analysis demonstrated VC4 as a significant negative of predictor pain outcomes at 1 month, but not longest follow-up, and advanced age as a significant positive predictor. Conclusion The degree of clinical improvement in all types of VC was excellent, but at longest follow-up VC type was not a significant predictor out outcome. However distal venous compression was significantly associated with worse outcomes at 1 month.

RESUMO

UNLABELLED: Determination of condylar inclination is important when restoring the occlusal surfaces of teeth. It is important to know the changing trends in horizontal condylar inclination with age so as to have an idea about the cuspal morphology. AIMS AND OBJECTIVES: a) to determine the effect of age changes in horizontal condylar inclination using articulator method and radiographic method (cephalometry) b) to compare the values of horizontal condylar inclination obtained using articulator method with that of cephalometric method c) to ascertain the symmetry of horizontal condylar angle on both right and left side on an articulator. 40 dentulous individuals with Angle's class I occlusion were selected for the study. They were divided into four groups Group I: 20-29 years, Group II: 30-39 years, Group III: 40-49 years, Group IV: 50-59 years. Horizontal condylar inclination was determined on right and left side for each individual using protrusive interocclusal record in a Dentatus (ARL) semiadjustable articulator. Cephalometric recording was carried out twice on the left side, once in centric occlusion position and then in protrusive position. The two radiographs were superimposed to draw a line connecting the shifting position of condylion on an acetate tracing paper. This line when joined with Frankfurt horizontal plane gives the horizontal condylar inclination. Analysis of variance (ANOVA) revealed that there was a significant difference in horizontal condylar angle values in all the four groups which were statistically significant. There is a decrease in horizontal condylar angle values from Group I to Group IV. Horizontal condylar values obtained by articulator method and cephalometric method showed no significant difference for all the four groups tested. When horizontal condylar values obtained on right and left sides of Dentatus articulator were compared there was not much of a significant difference. Horizontal condylar values showed a decreasing trend with increasing age, i.e, as age advances there is a flattening of condylar head. Both articulator and cephalometric method yielded no significantly different values and hence both the methods can be used for determining condylar inclination. The difference in values of horizontal condylar angle on right and left sides were insignificant.

RESUMO

Objective: This study aims at understanding the level of knowledge, attitude, and practice of breastfeeding among mothers and the factors associated with good knowledge about breastfeeding. Materials and methods: A cross-sectional study among 251 mothers of infants admitted in the pediatric wards of SAT Hospital, Thiruvananthapuram was conducted during November-December 2019. The mothers of infants born between 37 and 42 weeks of gestation and without major birth defects were included in the study. The data were entered into an MS Excel sheet and analyzed using Statistical Package of Social Sciences version 26.0. Significance of association was tested using Chi-square test and multivariate analysis was done using binary logistic regression test. Results: The mean age of the participants was 26.25 (SD 4) years. On multivariable analysis, higher education and older age were found to be significantly associated with good knowledge. Independent sample T-Test results show that there was a statistically significant difference between the mean age of mothers with good knowledge (26.4(±4), 25.14(±3.7)), p-0.015 and statistically significant association was found between the mean attitude scores (34.07(5.58)) with current breastfeeding practices (p=0.002). Chi-square test shows that exclusive breastfeeding was significantly associated with the mother's age (p=0.006); 64.2% of women practicing exclusive breastfeeding were less than 25 years of age. This study also demonstrated a significant association between the initiation of breastfeeding within an hour and exclusive breastfeeding (p=0.003). Conclusion: This study shows that mothers with higher age and higher educational qualifications were significantly associated with good knowledge about breastfeeding. Even though mothers have good knowledge, nearly half the mothers only exclusively breastfeed their infants for six months. Improving the educational qualification of women and increasing awareness about the benefits of breastfeeding among young women will promote breastfeeding practices.

RESUMO

Background: Left ventricular diastolic dysfunction (LVDD) is an early manifestation of cirrhotic cardiomyopathy. Few studies have addressed its clinical significance in cirrhosis. We assessed the association of LVDD with the factors affecting cirrhosis patients' severity, complications, and survival. Methods: A total of 203 cirrhosis patients were enrolled and underwent investigations, including 2-dimensional echocardiography with tissue Doppler imaging, and 139 patients with LVDD (cases) were compared with 64 patients without LVDD (controls). Logistic regression and Kaplan-Meier analysis were applied. Results: Mean age was 52.76±10 years. Among LVDD patients, 56% had grade-1, and 44% had grade-2 LVDD. Cirrhosis related to NASH had a more significant association with LVDD (P<0.001) than other etiologies. LVDD was significantly associated with a greater incidence of Child-Turcotte-Pugh (CTP) class C (P<0.001), higher model for end-stage liver disease scores (P=0.001), duration of cirrhosis >2 years since diagnosis (P=0.028), ascites (P<0.001), hepatic encephalopathy (P<0.010), hepatorenal syndrome (P<0.001), and a history of obesity (P=0.004). Multivariate analysis showed that higher CTP score, ascitic fluid protein and prolonged QTc interval were independently associated with LVDD (P=0.009; P=0.018; P=0.016, respectively). Kaplan-Meier survival analysis showed significantly poorer survival status in patients with higher grades of LVDD (P<0.001). The area under the receiver operating characteristic curve (0.78) was greatest for ascitic fluid protein in predicting LVDD, with a cutoff of >1 g/dL. Conclusions: Higher CTP score, prolonged QTc, higher ascitic fluid protein levels, and poor survival are significantly associated with LVDD. Ascitic fluid protein >1 g/dL could be an indicator for evaluating LVDD.

RESUMO

The essential oil extracted from Melissa officinalis (MOEO) exhibits a wide range of therapeutic properties, including antioxidant, antibacterial, and antifungal activities. The current research aimed to analyze the mechanical, barrier, chemical, and antioxidant properties of pectin and collagen-based films. Hydrogel-based films loaded with varying concentrations of MOEO (0.1%, 0.15%, and 0.2%) were prepared by solvent-casting method, and their physicochemical as well as antioxidant properties were examined. GC-MS analysis revealed the presence of major components in MOEO such as 2,6-octadienal, 3,7-dimethyl, citral, caryophyllene, geranyl acetate, caryophyllene oxide, citronellal, and linalool. Fourier transform infrared (FTIR) results revealed the interaction between components of the essential oil and polymer matrix. Scanning electron microscopy (SEM) revealed that films loaded with the highest concentration (0.2%) of MOEO showed more homogeneous structure with fewer particles, cracks, and pores as compared to control film sample. MOEO-incorporated films exhibited higher elongation at break (EAB) (30.24-36.29%) and thickness (0.068-0.073 mm); however, they displayed lower tensile strength (TS) (3.48-1.25 MPa) and transparency (87.30-82.80%). MOEO-loaded films demonstrated superior barrier properties against water vapors. According to the results, the incorporation of MOEO into pectin-collagen composite hydrogel-based films resulted in higher antioxidant properties, indicating that MOEO has the potential to be used in active food packaging material for potential applications.

RESUMO

Context: A career as a doctor makes him prone to develop health issues like obesity and obesity-related noncommunicable diseases. Aims: This study aims to find the burden and determinants of obesity among Modern Medicine doctors in Kerala. Settings and Design: We conducted a cross-sectional study among 240 doctors working in South Kerala from 2018 to 2019. Methods and Material: The sample size was calculated using a formula and stratified random sampling was done for the selection of study participants. An interviewer-administered structured questionnaire was used for data collection. Physical activity was measured using International Physical Activity Questionnaire. Statistical Analysis: Data were entered in MS Excel and was analyzed using Statistical Package for Social Sciences version 26.0. The significance of association was tested using the χ2 test. Binary logistic regression was done to predict the factors associated with overweight and obesity. Results: Out of 240 study participants, 128 (54%) were females and 112 (46%) were males. Among the 240 doctors, 54% (114) were either overweight or obese. A low level of physical activity was reported among 54.5% of doctors. Male gender odds ratio (OR) = 2.8 (95% confidence interval [CI] = 1.29-6.06), nuclear family OR = 2.7 (95% CI = 1.32-5.42), daily hours of sleep <6 hours OR = 4.92 (95% CI = 2.29-10.5), history of obesity among parents OR = 3.54 (95% CI = 1.04-12.02), reported the presence of private practice OR = 3.34 (95% CI = 1.25-8.96), and holding a graduation degree alone were found to be significantly associated with obesity. Conclusions: The study found that majority of the doctors (55%) were either overweight or obese. Awareness and behavior change communication among doctors on modifiable risk factors like having adequate sleep and reducing the hours spent in private practice is needed to reduce the burden of obesity among doctors.

RESUMO

Objective: This study aims to assess the knowledge, attitude, and practices regarding menstrual cups use and the factors associated with it among females of the reproductive age group in an urban setting of South Kerala. Materials and methods: We conducted a cross-sectional study from December 2021 to January 2022 among females of the reproductive age group. Data was entered in MS Excel and was analyzed using Statistical Package for Social Sciences version 26.0. The significance of association was tested using the Chi-square test. Binary logistic regression was done to predict the factors associated with knowledge levels regarding menstrual cup. Results: The mean age of study participants was 25.68(SD 6.64) years. Lack of knowledge (22.6%) and fear of insertion (56.2%) were the major reasons for not trying a menstrual cup. Out of the 350 study participants, 258(73.7%) had good knowledge scores and 92(26.3%) had poor knowledge scores. Discomfort and leakage were the most important problems reported by participants. A statistically significant association was found between younger age, educational status, socioeconomic, status, marital status of females in the reproductive age group, and knowledge about the menstrual cup. Conclusion: Most of the participants (93.4%) were aware of menstrual cups. Even though two third of the participants had good knowledge regarding menstrual cups, only 15.1% have tried to use a menstrual cup. Fear of insertion was the most common concern for not trying a menstrual cup. Discomfort and leakage were the most important problems reported by participants. Younger age and higher educational qualifications were found to be independently associated with knowledge levels regarding menstrual cups.

RESUMO

BACKGROUND: In the context of the largest dengue outbreak in the state of Kerala, India in 2017, along with global evidence of changing epidemiology of dengue virus and its distribution, this study was planned to understand the epidemiological pattern of dengue infection and contemplate the clinical presentations of different serotypes. METHODS: This cross-sectional study was conducted in the Thiruvananthapuram and Kollam districts of Kerala, India, spanning 3 y from 2017 to 2019. We recruited adult patients based on the World Health Organization case definition of probable dengue fever to study their virological, spatial and clinical characteristics. RESULTS: Dengue infection was identified in 113 (33.9%) of the 333 probable dengue patients recruited. Dengue virus 1 (DENV1), along with its combinations (59.09%), was the predominant serotype during 2017, followed by DENV2. There was a marked increase in the proportion of DENV4 cases (34.56%) and concurrent infections (26%) in 2019. DENV3 infections were more likely to present with warning signs (adjusted relative risk 6.14 [95% confidence interval 1.3 to 29.4]) and a significantly lower platelet count (p=0.02). CONCLUSIONS: The results highlight the hyperendemicity of dengue infection in the state and the changing pattern of dengue virus predominance along with redominance. The rise in DENV4 and concurrent infections put forth the possibility of a more severe future outbreak.
