Antecedentes existe una relación entre el uso de Instagram y diferentes influencias e interacciones con el bienestar y salud mental de este grupo etario. Objetivo Reconstruir las representaciones sociales acerca de la red social Instagram de adultos emergentes con diferentes niveles de bienestar psicológico y autoestima corporal. Método redes semánticas naturales y entrevistas semiestructuradas fueron aplicadas a N=12 adultos emergentes (19 - 27 años) divididos en dos grupos según sus niveles de autoestima corporal y bienestar psicológico. El análisis de datos estuvo basado en análisis de redes semánticas naturales y algunos procedimientos de codificación teórica. Resultados se muestra la presencia del concepto de "acoso" como núcleo central de la representación social de Instagram en el grupo con baja autoestima corporal y bajo bienestar psicológico, a diferencia del grupo con alta autoestima corporal y alto bienestar psicológico en donde el núcleo central fue "red social". Conclusiones en los grupos estudiados, se encontraron dos representaciones sociales diferentes respecto de Instagram. Estos resultados pueden ser relevantes para aportar a llenar el vacío de conocimiento sobre los significados subjetivos colectivos de los adultos emergentes, teniendo implicancias en la mejor comprensión de las diversas formas de relación que establecen con esta y otras redes sociales.
Background There is a relationship between the use of Instagram and various influences and interactions with the well-being and mental health of this age group. Objective To reconstruct the social representations of the Instagram social network among emerging adults with different levels of psychological well-being and body esteem. Method Natural semantic networks and semi-structured interviews were conducted with N=12 emerging adults (19 - 27 years old) divided into two groups based on their body self-esteem and psychological well-being levels. Data analysis relied on natural semantic network analysis and theoretical coding. Results The concept of "harassment" is revealed as the central core of the social representation of Instagram in the group with low body self-esteem and low psychological well-being, unlike the group with high body esteem and high psychological well-being where the central core was the "social network" itself. Conclusions Two different social representations of Instagram were found in the studied groups. These results could contribute to filling the knowledge gap about the collective subjective meanings of emerging adults, impacting the better understanding of the diverse relationships they establish with this and other social networks.

INTRODUCTION: Telerehabilitation advanced significantly with the emergence of COVID-19 and the recommendation of limiting physiotherapist-patient contact time whenever practicable. The effectiveness of telerehabilitation on those who had a longer stay in hospital and on oxygen support following discharge is still under question. OBJECTIVES: To evaluate the effects after six weeks of pulmonary telerehabilitation on exercise tolerance, fatigue level, perceived exertion, symptoms of depression and quality of life in patients surviving COVID-19. MATERIALS AND METHODS: A quasi-experimental study was conducted on 25 post-COVID-19 patients following discharge in a home environment setting. The participants were advised to prepare equipment such as oxygen concentrator, B-type oxygen cylinder (backup), lengthy oxygen tubes, finger pulse oximeter, mini static pedal exerciser, incentive spirometry, weight cuffs or water bottles and sandbags. After six weeks of telerehabilitation, the patients underwent assessments including initial oxygen saturation (SPO2), heart rate, peak oxygen demand during exercise to maintain baseline SPO2, peak heart rate, maximum drop in SPO2, recovery time to baseline SPO2 measured with a pulse oximeter and stopwatch, peak perceived exertion using the Borg Dyspnea Scale, peak fatigue score using the visual analog scale (VASF), quality of life assessed with the SF-36 questionnaire, and mental health status evaluated with the Hamilton Depression Scale (HAMD). One-way repeated measure ANOVA and paired t-test were used. RESULTS: Significant improvements following the intervention on the initial SPO2 (F (2.12, 23.13) = 21.0, p< 0.05) and quality of life also showed significant improvement (mean difference =29.92, p< 0.05). CONCLUSION: Six weeks of comprehensive pulmonary telerehabilitation with simple equipment improved tolerance to exercise, fatigue, perceived exertion, symptoms of depression and quality of life for post-COVID-19 patients.
INTRODUÇÃO: A telereabilitação avançou significativamente com o surgimento da COVID-19 e a recomendação de limitar o tempo de contato entre fisioterapeutas e pacientes sempre que possível. A eficácia da telereabilitação em pacientes que permaneceram mais tempo no hospital e necessitaram de suporte de oxigênio após a alta ainda está em questão. OBJETIVO: Para avaliar os efeitos após seis semanas de telereabilitação pulmonar na tolerância ao exercício, nível de fadiga, percepção de esforço, sintomas de depressão e qualidade de vida em pacientes sobreviventes de COVID-19. MATERIAIS E MÉTODOS: Foi realizado um estudo quase-experimental com dezesseis pacientes pós-COVID-19 selecionados de um hospital multispecializado. Os participantes foram orientados a preparar equipamentos como concentrador de oxigênio, cilindro de oxigênio tipo B (reserva), tubos de oxigênio longos, oxímetro de pulso, exercitador de pedal estático, espirômetro incentivador, pesos de tornozelo ou garrafas d'água e sacos de areia. Após seis semanas de telereabilitação, os pacientes foram submetidos a avaliações, incluindo saturação inicial de oxigênio (SPO2), frequência cardíaca, demanda máxima de oxigênio durante o exercício para manter a SPO2 basal, frequência cardíaca máxima, queda máxima na SPO2, tempo de recuperação para SPO2 basal medido com um oxímetro de pulso e cronômetro, esforço percebido máximo usando a Escala de Dispneia de Borg, pontuação máxima de fadiga usando a escala analógica visual (VASF), qualidade de vida avaliada com o questionário SF-36 e estado de saúde mental avaliado com a Escala de Depressão de Hamilton (HAMD). RESULTADOS: Melhorias significativas após a intervenção foram observadas na SPO2 inicial (F (2,12, 23,13) = 21,0, p <0,05) e na frequência cardíaca (F (1,839, 20,23) = 43,73, p <0,05), demanda máxima de oxigênio durante o exercício para manter a SPO2 basal (F (1,487, 16,36) = 8,96, p <0,05), esforço percebido máximo (F (5, 55) = 112,51, p <0,05), pontuação máxima de fadiga (F (1,755, 19,30) = 67,44, p <0,05), frequência cardíaca máxima (F (1,798, 19,78) = 50,99, p <0,05), queda máxima na SPO2 (F (2,467, 27,14) = 41,46, p <0,05) e tempo máximo de recuperação para alcançar a SPO2 basal (F (5, 55) = 78,89, p <0,05). A análise de seis semanas pós-intervenção nos sintomas depressivos (diferença média = 11,25, p <0,05) e na qualidade de vida também mostrou melhoria significativa (diferença média = 29,92, p <0,05). CONCLUSÃO: Seis semanas de telereabilitação pulmonar abrangente com equipamentos simples melhoraram a tolerância ao exercício, a fadiga, a percepção de esforço, os sintomas de depressão e a qualidade de vida em pacientes pós-COVID-19.

Objectives@#This study investigated factors associated with the retention of people living with human immunodeficiency virus (HIV) on antiretroviral therapy (ART) during the first 3 years of treatment. @*Methods@#A retrospective study using electronic health records was conducted at a tertiary hospital in Jakarta, Indonesia. Adult HIV-positive patients who started ART from 2010 until 2020 were included. A binary logistic regression model was used to identify factors associated with ART retention in the first 3 years. @*Results@#In total, 535 respondents were included in the analysis. The ART retention rates for the first, second, and third years were 83.7%, 79.1%, and 77.2%, respectively. The multivariate analysis revealed a negative association between CD4 count when starting ART and retention. Patients with CD4 counts >200 cells/mL were 0.65 times less likely to have good retention than those with CD4 counts ≤200 cells/mL. The year of starting ART was also significantly associated with retention. Patients who started ART in 2010-2013 or 2014-2016 were less likely to have good retention than those who started ART in 2017-2020, with adjusted odds ratios of 0.52 and 0.40, respectively. Patients who received efavirenz-based therapy were 1.69 times more likely to have good retention than those who received nevirapine (95% confidence interval, 1.05 to 2.72). @*Conclusions@#Our study revealed a decline in ART retention in the third year. The CD4 count, year of enrollment, and an efavirenz-based regimen were significantly associated with retention. Patient engagement has long been a priority in HIV programs, with interventions being implemented to address this issue.

Background@#Immune profiling has become an important tool for identifying predictive, prognostic and response biomarkers for immune checkpoint inhibitors from tumor microenvironment (TME). We aimed to build a multiplex immunofluorescence (mIF) panel to apply to formalin-fixed and paraffin-embedded tissues in mice tumors and to explore the programmed cell death protein 1/ programmed cell death 1 ligand 1 (PD-1/PD-L1) axis. @*Results@#An automated eight-color mIF panel was evaluated to study the TME using seven antibodies, including cytokeratin 19, CD3e, CD8a, CD4, PD-1, PD-L1, F4-80 and DAPI, then was applied in six mice lung adenocarcinoma samples. Cell phenotypes were quantified by software to explore the co-localization and spatial distribution between immune cells within the TME. This mice panel was successfully optimized and applied to a small cohort of mice lung adenocarcinoma cases. Image analysis showed a sparse degree of immune cell expression pattern in this cohort.From the spatial analysis we found that T cells and macrophages expressing PD-L1 were close to the malignant cells and other immune cells. @*Conclusions@#Comprehensive immune profiling using mIF in translational studies improves our ability to correlate the PD-1/PD-L1 axis and spatial distribution of lymphocytes and macrophages in mouse lung cancer cells to provide new cues for immunotherapy, that can be translated to human tumors for cancer intervention.

Abstract: This study aimed to estimate the prevalence and identify social factors and preventive strategies associated with the coronavirus disease 2019 (COVID-19) in socio and economically vulnerable people (recyclable waste pikers, immigrants/refugees, and homeless people) in Goiânia, Goiás State, Central-Western Brazil. A cross-sectional study was conducted from July 2020 to October 2020. COVID-19 positivity was defined as a positive total anti-SARS-COV-2 antibody test and/or RNA test for SARS-COV-2. Univariable and multiple regression analyses were performed to identify the variables associated with COVID-19. Of the 594 participants, 47.3% were recyclable waste pickers, 29.6% were immigrants/refugees, and 23.1% were homeless people. The positivity for SARS-CoV-2 RNA was 14.1%, whereas for anti-SARS-CoV-2 a total of 30.8% were positive, and 39.4% were positive for at least one COVID-19 marker. Among the 541 individuals, being immigrants/refugees, not wearing a surgical mask, and having three or more people sleeping in the same room were associated with SARS-CoV-2 infection, while using TV news as the main source of information about the pandemic was a protective predictor of COVID-19. This study revealed ethnic and socioeconomic inequalities in the prevalence of COVID-19 among impoverished people in Brazil. Additionally, a high prevalence of COVID-19 was detected in all three groups. Developing new strategies to combat and prevent communicable diseases affecting this population is essential for mitigating future and ongoing pandemics.
Resumo: Este estudo teve como objetivo estimar a prevalência da COVID-19 e identificar fatores sociais e estratégias preventivas associadas a essa doença em pessoas em situação de vulnerabilidade socioeconômica (catadores de lixo, imigrantes/refugiados e moradores de rua) em Goiânia, Estado de Goiás, na região central do Brasil. Trata-se de um estudo transversal realizado de julho a outubro de 2020. Foram considerados positivos para a covid-19 indivíduos que apresentaram um teste de anticorpos anti-SARS-COV-2 e/ou teste de RNA para SARS-COV-2 com resultado positivo. Foram realizadas análises de regressão univariável e múltipla para identificar as variáveis associadas à COVID-19. Dos 594 participantes, 47,3% eram catadores de lixo reciclável, 29,6% eram imigrantes/refugiados e 23,1% eram moradores de rua. A positividade foi de 14,1% para o RNA do SARS-CoV-2, 30,8% para o total de anti-SARS-CoV-2 e 39,4% para pelo menos um marcador da COVID-19. Entre os 541 indivíduos, ser imigrante/refugiado, não usar máscara cirúrgica e ter três ou mais pessoas dormindo no mesmo quarto foram fatores associados à infecção por SARS-CoV-2, enquanto confiar em informações sobre a pandemia, principalmente aquelas transmitidas por noticiários de TV, foi um indicador de proteção contra a COVID-19. Este estudo revelou desigualdades étnicas e socioeconômicas na prevalência da COVID-19 entre pessoas de baixa renda no Brasil. Além disso, uma alta prevalência de COVID-19 foi detectada nos três grupos. O desenvolvimento de novas estratégias para combater e prevenir doenças transmissíveis que afetam essa população é essencial para mitigar pandemias futuras e atuais.

Introduction: Periodontitis is a pandemic, with about 14 percent of people worldwide already suffering from severe periodontitis. Early intervention in the disease could probably reduce its progression and eliminate the need for the extraction of affected teeth. Quercetin is a probable candidate as it has exemplary anti-inflammatory properties. The presence of phenolic hydroxyl groups in them greatly contributes to their antioxidant and anti-inflammatory activities. Objectives: The study introduces the formulation of Quercetin mouthwash and assesses its anti-inflammatory properties in comparison to Diclofenac sodium. Methods: Quercetin mouthwash was prepared using a commercially procured bioactive agent. One standard nonsteroidal anti-inflammatory drug, Diclofenac was used as a reference drug. The percentage inhibition of protein denaturation was calculated and its anti-inflammatory properties were evaluated through Bovine Serum Albumin Assay and Egg Albumin Assay. Results: Quercetin mouthwash showed parallel anti-inflammatory properties and showed a proportionate increase in anti-inflammatory properties with the increase in the concentration of the mouthwash. Comparable inhibition of protein denaturation at 10µl and 50µl concentrations with a proportionate variation of 1 percent (p>0.05) to the control in Egg Albumin Assay and 47 percent and 83 percent denaturation at 10µl and 50µl of Bovine Serum Albumin Assay were observed. Conclusion: Quercetin mouthwash has shown significant anti-inflammatory activity and hence is considered a potent anti-inflammatory agent comparable to Diclofenac sodium. It is found to be a suitable agent as an oral formulation for reducing the progression of inflammatory conditions(AU)
Introducción: La periodontitis es una pandemia, ya que alrededor del 14 por ciento de las personas en todo el mundo padecen periodontitis grave. Una intervención precoz en la enfermedad podría, probablemente, reducir su progresión y eliminar la necesidad de extraer los dientes afectados. La quercetina es un candidato probable, ya que tiene propiedades antiinflamatorias ejemplares. Su presencia de grupos hidroxilos fenólicos contribuye en gran medida a sus actividades antioxidantes y antiinflamatorias. Objetivos: El estudio presenta la formulación del colutorio de quercetina y evalúa sus propiedades antiinflamatorias en comparación con el diclofenaco sódico. Métodos: Se preparó un colutorio de quercetina, utilizando un agente bioactivo obtenido comercialmente. Se utilizó como fármaco de referencia un antiinflamatorio no esteroideo estándar, el diclofenaco. Se calculó el porcentaje de inhibición de la desnaturalización de proteínas y se evaluaron sus propiedades antiinflamatorias mediante ensayo con albúmina de suero bovino y con albúmina de huevo. Resultados: El colutorio de quercetina mostró propiedades antiinflamatorias paralelas y mostró un aumento proporcional de las propiedades antiinflamatorias con el aumento de la concentración del colutorio. Se observó una inhibición comparable de la desnaturalización de proteínas a concentraciones de 10µl y 50µl con una variación proporcional del 1 por ciento (p > 0,05), respecto al control en el ensayo de albúmina de huevo y una desnaturalización del 47 por ciento y 83 por ciento a 10µl y 50µl del ensayo de albúmina de suero bovino. Conclusiones: El enjuague bucal de quercetina ha mostrado una actividad antiinflamatoria significativa, por lo que se considera un potente agente antiinflamatorio comparable al diclofenaco sódico. Se considera un agente adecuado como formulación oral para reducir la progresión de las afecciones inflamatorias(AU)

Objective: The past few years have seen a rapid advancement in the management of keratoconus (KC). However, there is no prescribed standard of care for the management of KC. This study evaluated the prevailing practice patterns among Indian ophthalmologists in the diagnosis and treatment of KC via an online survey. Methods: This was a survey?based cross?sectional study in which a questionnaire (Supplement 1) was created. Questions pertaining to the practicing experience, setting of practice, and training background were asked in addition to the investigations done and decision making in KC management. Responses were collected via Survey Monkey (Survey Monkey, Palo Alto, California, USA) and statistical analysis performed using R software (4.1.3). Results: The survey was answered by 273 ophthalmologists. Pentacam was the most used topographer (195 users), followed by Orbscan (41 users), Sirius (34 users), and Galilei (3 users). The lowest limit of pachymetry for performing collagen crosslinking (CXL) was 400? for most practitioners. More than half the respondents (50.55%) did not perform photorefractive keratectomy (PRK) or intracorneal ring segment (ICRS) implantation in a suitable patient. Accelerated 10?minute protocol (9 mW/cm2 for 10 minutes) was the most commonly (54.21%) used for CXL, followed by Dresden protocol (3 mW/cm2 for 30 minutes) (36.63%). When a patient was unsuitable for CXL, 55.31% surgeons advise contact lens (CL) trial, 35.16% surgeons advise keratoplasty, 26.74% surgeons perform stromal augmentation, and 7.69% surgeons advise spectacle correction. Corneal scar was the most common indication (49.45%) for performing keratoplasty. Conclusion: Topography remains the most used diagnostic modality for initial diagnosis. Optical coherence tomography and epithelial mapping are increasingly being used for early diagnosis of KC. Not all ophthalmologists were comfortable performing ICRS or PRK. When patients are unsuitable for CXL, CL trial remains the most frequently advised option followed by keratoplasty.

Background: Cutaneous mucormycosis has shown a significant upsurge during the COVID-19 pandemic. Due to the rapid progression and high mortality of cutaneous mucormycosis in this context, it is important to identify it early. However, very few studies report detailed clinical descriptions of cutaneous mucormycosis in COVID-19 patients. Objectives: To describe mucocutaneous lesions of COVID-19-associated mucormycosis based on clinical morphology and attempt to correlate them with radiological changes. Methods: A retrospective cross-sectional study was conducted at a tertiary care centre from 1st April to 31st July 2021. Eligibility criteria included hospitalised adult patients of COVID-19-associated mucormycosis with mucocutaneous lesions. Results: All subjects were recently recovering COVID-19 patients diagnosed with cutaneous mucormycosis. One of fifty-three (2%) patients had primary cutaneous mucormycosis, and all of the rest had secondary cutaneous mucormycosis. Secondary cutaneous mucormycosis lesions presented as cutaneous-abscess in 25/52 (48%), nodulo-pustular lesions in 1/52 (2%), necrotic eschar in 1/52 (2%) and ulcero-necrotic in 1/52 (2%). Mucosal lesions were of three broad sub-types: ulcero-necrotic in 1/52 (2%), pustular in 2/52 (4%) and plaques in 1/52 (2%). Twenty out of fifty-two patients (38%) presented with simultaneous mucosal and cutaneous lesions belonging to the above categories. Magnetic resonance imaging of the face showed variable features of cutaneous and subcutaneous tissue involvement, viz. peripherally enhancing collection in the abscess group, “dot in circle sign” and heterogeneous contrast enhancement in the nodulo-pustular group; and fat stranding with infiltration of subcutaneous tissue in cases with necrotic eschar and ulcero-necrotic lesions. Limitations: The morphological variety of cutaneous mucormycosis patients in a single-centre study like ours might not be very precise. Thus, there is a need to conduct multi-centric prospective studies with larger sample sizes in the future to substantiate our morphological and radiological findings. Conclusions: COVID-19-associated mucormycosis patients in our study presented with a few specific types of mucocutaneous manifestations, with distinct magnetic resonance imaging findings. If corroborated by larger studies, these observations would be helpful in the early diagnosis of this serious illness.

Childhood pneumonia is still a significant clinical and public health problem. India contributes the highest number of deaths due to pneumonia, accounts for about 20% of global mortality among under five children. Various etiologic agents including bacteria, viruses and atypical organism are responsible for childhood pneumonia. Recent studies suggest that viruses are one of the major causes of childhood pneumonia. Among viruses, respiratory syncytial virus has got great attention and several recent studies are reporting it as an important organism for pneumonia. Lack of exclusive breast feeding during first six months, improper timing of start and content of complimentary feeding, anemia, undernutrition, indoor pollution due to tobacco smoking and use of coal and wood for cooking food and lack of vaccinations are important risk factors. X-ray chest is not routinely performed to diagnose pneumonia while use of lung ultrasound is increasing to detect consolidation, pleural effusion, pneumothorax and pulmonary edema (interstitial syndrome). Role of C-reactive protein (CRP) and procalcitonin is similar, to differentiate between viral and bacterial pneumonia, however duration of antibiotics is better guided by procalcitonin. Newer biomarkers like IL-6, presepsin and triggering receptor expressed on myeloid cells 1 are needed to be evaluated for their use in children. Hypoxia is significantly associated with childhood pneumonia. Therefore, use of pulse oximetry should be encouraged for early detection and prompt treatment of hypoxia to prevent adverse outcomes. Among the available tools for risk of mortality assessment in children due to pneumonia, PREPARE score is the best but external validation will be needed.

Background: Photic sneeze reflex (PSR) also known as autosomal dominant compelling helioophthalmic outburst is a rare condition characterized by uncontrolled sneezing in response to bright light. The exact mechanism causing this is poorly understood. However, various hypotheses have been proposed. Ophthalmic examination involves exposing the patient to bright light like slit lamp, indirect ophthalmoscopy and surgical microscope, which can trigger sneezing in PSR patients. Purpose: The purpose of this video is to draw light to this rare phenomenon and its implication in ophthalmic surgery. Synopsis: A 74?year?old male patient presented with diminution of vision in left eye. On routine slit lamp and IDO examination, patient had repeated sneezing. We diagnosed him to have photic sneeze reflex. He had pseudophakic bullous keratopathy in the right eye and senile immature cataract in the left eye. Taking into consideration his one eyed status and PSR, measures were taken accordingly and cataract surgery was performed uneventfully. We describe in this video the challenges encountered with this phenomenon and approach in such cases. Highlights: In this video, we tried to give an idea about photic sneeze reflex and its theories. Also, we tried to bring out the impact of PSR on ophthalmologic practice.

Background: Glenohumeral joint is highly susceptible to dislocation due to its wide range of movements. Recurrent anterior shoulder dislocations are common in young adults. The Bristow Latarjet procedure is one of the effective techniques for the treatment of recurrent anterior shoulder dislocation. This study aimed to assess the clinical and functional outcome of the Bristow Latarjet procedure in the management of recurrent anterior shoulder dislocation. Material & Methods: This prospective interventional study was conducted in the Department of Orthopaedic Surgery, BSMMU, from October 2017 to September 2019. Within this period, a total of 40 cases of recurrent anterior shoulder dislocation that meet inclusion criteria were taken as a sample. Patients were evaluated both pre and postoperatively for functional outcomes according to Rowe’s score for instability. A purposive non-randomized sampling technique was used in this study. All the data were compiled and sorted properly and the quantitative data were analyzed statistically by using Statistical Package for Social Science (SPSS-25). The results were expressed as frequency, percentage and mean ± SD. Paired Student’s‘t’ test was performed to compare pre and final postoperative follow-up. The level of significance was calculated at a confidence interval of 95% and p-value <0.05. Results: : In this study age of the patient ranged from 18-40 years and the mean age was 28.2±6.3. 29(72.5). Surgery was done within 4-6 months of the first dislocation in 5 patients, within 6-12 months in 21 patients and after 12 months in 14 patients. The mean (±SD) Rowe score for instability was significantly (p<0.001) higher 6 months after the Bristow Latarjet procedure at 91.87(±9.00) in comparison to preoperative periods 52.62(±18.40). Results were excellent in 32(80%), good in 4(10%), fair in 3(7.5%) and poor in 1(2.5%) patients. 36(90%) patients were in the satisfactory group and only 4(10%) in the unsatisfactory group. Only 1(2.5%) patient developed screw migration, 2(5%) patients developed subluxation, and 1(2.5%) patient developed postoperative arthritis. Conclusion: It can be concluded that the Bristow-Latarjet procedure is a very effective and safe procedure with reduced complications, presenting very satisfactory functional results in the treatment of recurrent anterior shoulder dislocation.

Introduction:Cardiac venous system is an important system for various cardiac interventional procedures such as cardiac catheterization. Various veins like right marginal vein, small cardiac vein (SCV), posterior vein of the left ventricle, left marginal vein, oblique vein of Marshall drain into coronary sinus. While anterior cardiac veins drain right ventricular wall directly into right atrium. Materials and Methods: An observational cross‑sectional study was conducted on thirty cadaveric hearts during a 2‑year period in Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Anatomy Department. The length, diameter of SCV, left marginal vein, posterior vein of the left ventricle, right marginal vein, and oblique vein of Marshall were taken. Results: The study reveals the length of SCV as 28.12 ± 22.87 mm. The length of right marginal vein and posterior vein of the left ventricle is having a significant correlation with age. The length of oblique vein of Marshall is lower in males as compared to females. A number of ACVs were significantly related to weight of cadaver in males. Conclusions: The present study provides data of cardiac veins for various cardiac interventional procedures.

Consumer behavior can be defined as the activities and the actions of people and organization that purchase and use economic goods and services, including the influence on these activities and actions. Marketers expect that by understanding what causes the consumers to buy particular goods and services, they will be able to determine which products are needed in the marketplace, which are obsolete, and how best to present the goods to the consumers. In the changing digital era, people buying online have drastically increased when compared to offline shopping. Existence of many online platforms has increased the choices for the consumers. It is a common rule in economics, that when there are more choices for the consumer, there is more competition. The online platforms has also developed there specializations like Myntra for fashion, amazon for electronics, big basket for food and so on. This specialization in online platforms has actually given various new factors for the consumers to compare the products. After the arrival of these many platforms, consumers have changed their view over the branding of products. There are consumers who are loyal to the brands in few products and there are also consumers who find only the best deals irrespective of branding. This paper studies the consumer's choices and behavior towards the brands in online shopping in a survey method.

Background: Cerebral palsy (CP) is the most common motor disability in childhood. Quality of life (QOL) has emerged as an important concept in childhood, especially for children with disabilities. CP has an impact on a child’s capacity to do activities of daily living thus affecting QOL of patients and their families. Aims and Objectives: The objective of present study was to assess the QOL in children with CP. Materials and Methods: In this study, 29 children with CP in the age group of 4–12 years were evaluated for QOL was assessed using CPQOL-Child Primary Caregiver Questionnaire (4–12 years). The questionnaire was completed by one of the parents or their caregiver. Scores for each domain of QOL were converted to a scale ranging from 0 to 100 and analyzed. Results: The scores as reported by the parents were low for each of the domains with maximum effect seen in functioning domain and least in pain domain. Girls had better QOL than boys. The QOL scores were negatively related to the severity of CP which was assessed by gross motor function classification system suggesting that severity of disability had negative impact on QOL. Conclusion: QOL of children with CP was found to be poor and was influenced by age, sex and motor functioning

Background: Heart rate recovery at 1st min (HRR 1 min) after graded treadmill exercise (GTX) is a predictor of parasympathetic function. Impaired HRR 1 min and obesity are strong predictors of metabolic syndrome and cardiovascular disorders. This study is done to asses HRR 1 min on apparently healthy obese young adults with body mass index (BMI) ?30, without any other metabolic syndrome components. Aims and Objectives: The objective of this study was to assess the parasympathetic function by estimating HRR 1 min after exercise in apparently healthy obese young adults of 18–30 years of age without any metabolic syndrome components and is compared with age- and gender-matched controls with normal BMI. Materials and Methods: Fifty obese young adults with BMI ?30 without any other metabolic syndrome component and 50 age- and gender-matched controls with BMI ?24.9 were selected and subjected to GTX according to modified Bruce protocol. Maximum heart rate reached during exercise (HRmax) and heart rate at 1st min of recovery phase (HR1min) were recorded. HRR 1 min was calculated as HRmax-HR1min and was analyzed. Results: This study showed significantly attenuated HRR 1 min in obese young adults compared to age- and gender-matched controls (mean 24.02 ± 8.87 vs. 42.42 ± 5.3, P < 0.001). Conclusion: HRR 1 min was significantly decreased in obese young adults, indicating attenuated parasympathetic function, who are at higher risk of developing chronic cardiovascular and other metabolic disorders.
RÉSUMÉ
Introduction The C-MAC D-blade was designed for difficult airway intubation scenarios. To facilítate easier and faster endotracheal intubation in the laryngoscopy paradox, an introducer is preferred. Hence, we decided to conduct a study to compare the 60° angled C-MAC stylet and the gum elastic bougie as aids to intubation while using the C-MAC D-blade laryngoscope in a simulated difficult airway setting. Objective To compare the ease of oral intubation with the use of the C-MAC stylet (60° angled stylet) versus intubation performed over a bougie inserted using the C-MAC D-blade guidance in patients with simulated restricted cervical mobility. Method Prospective, randomized controlled single-center study. Intubation using the C-MAC D-blade laryngoscope was performed in 48 surgical patients randomly assigned to 2 groups of 24 each: Stylet group, Group S (using 60° angled stylet) and Bougie group, Group B (using bougie) after providing manual in-line stabilization to restrict cervical mobility. The Mann-Whitney U test and the Chi square test were used as applicable. Results The use of stylet resulted in easier (Group S 75% vs. Group B 16.7%) and faster (Group S 26.83 ± 8.61s vs. Group B 47.18 ± 16.46s) intubation with fewer attempts compared to group B. Both groups experienced a similar hemodynamic stress response to intubation. Conclusions The 60° angled C-MAC Stylet is a more effective and time-saving intubation aid with C-MAC D-blade compared to bougie.
Introducción: El videolaringoscopio C-MAC D-blade se diseñó para los casos de intubación de la vía aérea difícil. Para facilitar una intubación más rápida y sencilla en la paradoja de la laringoscopía se prefiere un introductor. Por tanto, decidimos realizar un estudio para comparar el estilete de 60° C-MAC y el bougie elástico de goma como ayudas para la intubación utilizando el laringoscopio C-MAC D-blade en una situación simulada de vía aérea difícil. Objetivo: Comparar la facilidad de intubación oral mediante el uso del estilete del C-MAC (estilete angulado de 60°) con la intubación realizada sobre un bougie insertado con la guía del C-MAC D0-blade en pacientes con restricción simulada de la movilidad cervical. Métodos: Estudio prospectivo, aleatorizado y controlado realizado en un solo centro. Se realizó intubación utilizando el laringoscopio C-MAC D-blade D en 48 pacientes quirúrgicos asignados aleatoriamente a 2 grupos de 24 cada uno: grupo de estilete, grupo S (con el estilete angulado de 60°) y el grupo de bougie o grupo B (con bougie) después de establecer una estabilización manual del eje para restringir la movilidad cervical. Se aplicaron las pruebas U de Mann-Whitney U y de Chi cuadrado según correspondiera. Resultados: Con el estilete fue más fácil (Grupo S 75% vs. Grupo B 16.7%) y más rápida (Grupo S 26.83 ± 8.61s vs. Grupo B 47.18 ± 16.46s) la intubación, requiriéndose un menor número de intentos en comparación con el Grupo B. Los dos grupos experimentaron un estrés hemodinámico similar en respuesta a la intubación. Conclusiones: El estilete angulado de 60° C-MAC es una ayuda más efectiva y ahorra más tiempo con el C-MAC D-blade en comparación con el bougie.

Objectives To compare the clinical profle and short-term outcome of children admitted with acute SARS-CoV-2 infection during the frst and second waves of the Coronavirus Disease (COVID-19). Methods This retrospective study was conducted in a tertiary care setting. A retrospective medical record review of all pediatric patients admitted with confrmed SARS-CoV-2 infection between March 2020 and September 2021 was conducted. Patients’ demographic data, pre-existing comorbidities, mode of presentation, and clinical course in the hospital were noted. The outcome measures were in-hospital mortality, need for intensive care, and invasive mechanical ventilation, duration of ICU, and hospital stay. Results One thousand and twenty-four children were recruited, 592 of the frst wave and 432 of the second wave. In the second wave, more children were admitted with respiratory distress (OR=3.38) and neurological manifestations (OR=4.61). There was a higher requirement of intensive care (OR=4.2) and invasive mechanical ventilation (OR=4.17). In-hospital mortality of the second wave was also increased (1.4% vs. 0.1%), but the diference was not statistically signifcant. Children with neurological comorbidities (OR=8.73), malnutrition (OR=3.01), and preterm babies (OR=6.8) were associated with severe COVID. Conclusion The clinical profle of the second wave of COVID-19 in children was diferent from the frst wave, with more respiratory distress and neurological manifestations at presentation. In the second wave, a signifcant increase in the incidence of severe infections requiring ICU care was observed.

Background: Although less painful injection techniques have been developed, most individuals still find palatal injection to be unpleasant. Aims: The purpose of this study was to evaluate the efficacy of single buccal infiltration versus conventional buccal and palatal infiltration for the removal of maxillary molar teeth. Fifty patie Materials and Methods: nts participated in a prospective randomized, split-mouth study, Group 1: 4% Articaine HCL infiltration – Only buccal, Group 2: 2% Lignocaine HCL – Buccal and palatal infiltration. Checking VAS score and Facial pain scale during Infiltration and during extraction. Factor analysis was used to determine the significance of the difference in mean scores between the two groups using both the independent sample t-test. Even though the Results: difference was not statistically significant (P > 0.05), patients in the articaine group reported much less discomfort during having their vital maxillary molars extracted compared to the lignocaine group. As was previously m Conclusion: entioned, it is feasible to avoid the palatal injection while removing molars from the maxilla. Specifically, the extraction of the upper molars, and buccal infiltration with articaine is a viable alternative to the use of traditional local anaesthetic.
