RESUMO
Management of type 2 diabetes mellitus (T2DM) largely relies on medication adherence of individuals with diabetes to achieve optimal glycemic control. The economic burden of diabetes could impede adherence, leading to a reduction in treatment efficacy and increased risk of complications. Furthermore, monotherapy in diabetes is losing traction due to its ineffectiveness in achieving early and sustained optimal glycemic control in a significant proportion of the population. Hence, clinicians prefer combination treatment due to their improved efficacy and safety. Considering these factors, the current review highlights the safety and efficacy of the affordable combination therapies, a dual therapy, glipizide + metformin, and a triple-drug combination of glimepiride + metformin + pioglitazone and its applicability in the management of T2DM among individuals with diabetes in India.
RESUMO
INTRODUCTION: Surgical stabilization of rib fractures (SSRF) using standard rib plating systems has become a norm in developed countries. However, the procedure has not garnered much interest in low-middle-income countries, primarily because of the cost. METHODS: This was a single-center pilot randomized trial. Patients with severe rib fractures were randomized into two groups: SSRF and nonoperative management. SSRF arm patients underwent surgical fixation in addition to the tenets of nonoperative management. Low-cost materials like stainless steel wires and braided polyester sutures were used for fracture fixation. The primary outcome was to assess the duration of hospital stay. RESULTS: Twenty-two patients were randomized, 11 in each arm. Per-protocol analysis showed that the SSRF arm had significantly reduced duration of hospital stay (22.6 ± 19.1 d versus 7.9 ± 5.7 d, P value 0.031), serial pain scores at 48 h and 5 d (median score 5, IQR (3-6) versus median score 7, IQR (6.5-8), P value 0.004 at 48 h and median score 2 IQR (2-3) versus median score 7 IQR (4.5-7) P value 0.0005 at 5 d), significantly reduced need for injectable opioids (9.9 ± 3.8 mg versus 4.4 ± 3.4 mg, P value 0.003) and significantly more ventilator-free days (19.9 ± 8.7 d versus 26.4 ± 3.2 d, P value 0.04). There were no statistically significant differences in the total duration of ICU stay (median number of days 2, IQR 1-4.5 versus median number of days 7, IQR 1-14, P value 0.958), need for tracheostomy (36.4% versus 0%, P value 0.155), and pulmonary and pleural complications. CONCLUSIONS: SSRF with low-cost materials may provide benefits similar to standard rib plating systems and can be used safely in resource-poor settings.

Background: Alzheimer's disease (AD) is a chronic neurodegenerative disease needing effective therapeutics urgently. Sildenafil, one of the approved phosphodiesterase-5 inhibitors, has been implicated as having potential effect in AD. Objective: To investigate the potential therapeutic benefit of sildenafil on AD. Methods: We performed real-world patient data analysis using the MarketScan® Medicare Supplemental and the Clinformatics® databases. We conducted propensity score-stratified analyses after adjusting confounding factors (i.e., sex, age, race, and comorbidities). We used both familial and sporadic AD patient induced pluripotent stem cells (iPSC) derived neurons to evaluate the sildenafil's mechanism-of-action. Results: We showed that sildenafil usage is associated with reduced likelihood of AD across four new drug compactor cohorts, including bumetanide, furosemide, spironolactone, and nifedipine. For instance, sildenafil usage is associated with a 54% reduced incidence of AD in MarketScan® (hazard ratio [HR]â=â0.46, 95% CI 0.32- 0.66) and a 30% reduced prevalence of AD in Clinformatics® (HRâ=â0.70, 95% CI 0.49- 1.00) compared to spironolactone. We found that sildenafil treatment reduced tau hyperphosphorylation (pTau181 and pTau205) in a dose-dependent manner in both familial and sporadic AD patient iPSC-derived neurons. RNA-sequencing data analysis of sildenafil-treated AD patient iPSC-derived neurons reveals that sildenafil specifically target AD related genes and pathobiological pathways, mechanistically supporting the beneficial effect of sildenafil in AD. Conclusions: These real-world patient data validation and mechanistic observations from patient iPSC-derived neurons further suggested that sildenafil is a potential repurposable drug for AD. Yet, randomized clinical trials are warranted to validate the causal treatment effects of sildenafil in AD.

BACKGROUND: Decreased diet intake and malnourishment have profound implications on cancer patients' quality of life and survival. Malnutrition increases the risk of postoperative complications, increases hospital length stays, reduces patient's tolerance to radiation and chemotherapy treatment, and results in poor response to treatment. In the present study, we intended to assess the nutritional status of cancer patients and find the correlation of body mass index with anthropometric and blood parameters. MATERIAL & METHODS: The study was prospective and cross-sectional, and 104 patients with newly diagnosed solid tumors were included. Patient demographics, symptoms, and anthropometric and blood parameters were collected. The correlation was estimated with Pearson's correlation coefficient. A p-value of less than 0.05 was considered significant. RESULTS: The association between stages of the disease, dental status, type of diet, and BMI was p=0.701, 0.216, and 0.422, respectively, and was not statistically significant. The anthropometric parameters mid upper arm circumference (MUAC cm), mid arm circumference (MAC cm), and triceps skinfold thickness (TSF mm) correlated with body mass index (BMI kg/m2) and had statistically significant p values of 0.0001, 0.0001, and 0.033, respectively. The correlation was assessed between hemoglobin, red cell distribution width, neutrophil-to-lymphocyte ratio, and serum albumin levels with BMI, but except for albumin (p=0.05), no other blood parameter correlated. CONCLUSION: Nutritional assessment is vital in recognizing patients at risk of treatment-associated complications and poor responders to treatment. In this study, BMI correlated with anthropometric parameters MUAC, MAMC, and TSF. Baseline dietary assessments of patients will help focus on the nutritional build-up of patients before starting treatment.
RESUMO
Acanthamoeba are free-living protozoa present ubiquitously in numerous environmental reservoirs that exist as an actively feeding trophozoite or a dormant cyst stage. The pathogenic Acanthamoeba are known to cause Acanthamoeba keratitis (AK) and granulomatous amoebic encephalitis (GAE). Despite their omnipresence, the number of infections is quite low. The reason behind this low frequency of Acanthamoeba infections could be the existence of many non-pathogenic strains or a successful host immune response to these infections. Studies in the past have proposed a few physiological parameters for the differentiation of pathogenic and non-pathogenic strains. Additionally, in vivo experiments are known to play an essential role in understanding the virulence of parasites, immunological aspects, and disease pathogenesis. The thermotolerance (30 °C, 37 °C, and 40 °C) and osmotolerance (0.5 M, 1 M, and 1.5 M) tests were performed on 43 Acanthamoeba isolates from patients with keratitis (n = 22), encephalitis (n = 5), and water samples (n = 16). In addition, the genotype of 10 Acanthamoeba isolates (keratitis (n = 2), encephalitis (n = 2), water (n = 6)) was determined and were then evaluated for pathogenicity on mouse model by inducing Acanthamoeba keratitis and amoebic encephalitis. The results of the thermotolerance and osmotolerance assays categorized 29/43 (67.4%) isolates as pathogenic, 8 as low pathogenic (18.6%), and the remaining 6 (13.9%) as non-pathogenic. The 10 Acanthamoeba isolates were categorized as T11 (5 isolates), T5 (2 isolates), T4 (2 isolates), and T10 (1 isolate) genotypes. Out of 10 Acanthamoeba isolates, 9 were successful in establishing AK, amoebic encephalitis, or both in the mice model, and a single isolate was found non-pathogenic. Two isolates from water samples were non-pathogenic in the physiological tests but successfully established Acanthamoeba infection in the mice model. The results of the physiological assays and in vivo experiments were analogous for 7 isolates while 1 isolate from the water was low pathogenic in the physiological assays but failed to produce pathogenicity during in vivo experiments. The physiological parameters are not very dependable to test the pathogenic potential of Acanthamoeba isolates, and thus results must always be validated by in vivo experiments. There is no infallible approach for determining the potential pathogenicity of environmental isolates of Acanthamoeba because several parameters regulate the pathogenic potential.

OBJECTIVES: This study estimates the frequency of cost-related oral health service avoidance (CROHSA) among lesbian, gay, and bisexual (LGB) individuals in Canada relative to heterosexual persons. METHODS: Heterosexual and sexual minority individuals in Canada were compared using the national probability-based Canadian Community Health Survey 2017-2018. Logistic regression was used to quantify associations between LGB status and CROHSA. Mediators were tested following Andersen's behavioral model of health service utilization and included partnership status, oral health status, presence of dental pain, educational attainment, insurance status, smoking status, general health status, and personal income. RESULTS: From our sample of 103,216 individuals, 34.8% of LGB individuals reported avoiding oral health care due to cost compared to 22.7% of heterosexual persons. Disparities were most pronounced among bisexual individuals (odds ratio [OR] 2.29 95% confidence interval [CI] 1.42, 3.49). Disparities persisted despite adjustment for confounding using age, gender/sex, and ethnicity (OR 2.23 95% CI 1.42, 3.49). Disparities were fully mediated by eight hypothesized mediators namely, educational attainment, smoking status, partnership status, income, insurance status, oral health status, and the presence of dental pain (OR 1.69 95% CI 0.94, 3.03). In contrast, lesbian/gay individuals did not have elevated odds of experiencing CROHSA compared to heterosexual individuals (OR 1.27 95% CI 0.84, 1.92). CONCLUSION: CROHSA is elevated for bisexual individuals relative to heterosexual individuals. Targeted interventions should be explored to improve oral healthcare access among this population. Future research should assess the role of minority stress and social safety on oral health inequities among sexual minority groups.

Purpose: AcrySof IQ Vivity is a unique non-diffractive extended depth of focus intraocular lens with wavefront-shaping X-WAVE technology. This study evaluated the cost-effectiveness of AcrySof IQ Vivity intraocular lens (DFT015) compared with standard aspheric monofocal intraocular lens (SN60WF), from a private health fund perspective in Australia. Methods: A Markov model was developed using the following health states: well, need for spectacles (near/distance/bifocal/varifocal), very bothersome visual disturbances (glare/haloes/starbursts) - with/without spectacles, and death. Model inputs were sourced from a randomized clinical study (NCT03010254), published literature, prostheses list and clinical opinion. A lifetime horizon (up to 30 years) was considered, and cost and health outcomes were discounted at 5% per annum. Model outcomes included incremental cost-effectiveness ratio defined as incremental cost per quality adjusted life year gain. Sensitivity and scenario analyses were also conducted. Results: Bilateral implantation of DFT015 intraocular lens provided quality adjusted life year gain of 0.16 at an incremental cost of AU$307 compared to bilateral SN60WF, leading to an incremental cost-effectiveness ratio of AU$1908/quality adjusted life year, well below the cost-effectiveness threshold (Range: AU$45,000-AU$75,000) typically used by Medical Services Advisory Committee in Australia. Results were most sensitive to intraocular lens costs, post-operative spectacle dependence, and disutility due to wearing glasses. Robustness of the results was further confirmed by probabilistic sensitivity analysis and scenario analyses. Conclusion: AcrySof IQ Vivity intraocular lens is a highly cost-effective treatment strategy with improved vision-related quality of life outcomes for presbyopic cataract surgery patients.
RESUMO
Objective: The timing and nature of surgical intervention for semisolid abnormalities are dependent upon distinguishing between adenocarcinoma-in-situ (AIS), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma (INV). We sought to develop and evaluate a quantitative imaging method to determine invasiveness of small, ground-glass lesions on computed tomography (CT) chest scans. Methods: The study comprised 268 patients from 4 institutions with resected (<=3 cm) semisolid lesions with confirmed histopathological diagnosis of MIA/AIS or INV. A total of 248 radiomic texture features from within the tumor nodule (intratumoral) and adjacent to the nodule (peritumoral) were extracted from manually annotated lung nodules of chest CT scans. The datasets were randomly divided, with 40% of patients used for training and 60% used for testing the machine classifier (Training DTrain, N=106; Testing, DTest, N=162). Results: The top five radiomic stable features included four intratumoral (Laws and Haralick feature families) and one peritumoral feature within 3 to 6 mm of the nodule (CoLlAGe feature family), which successfully differentiated INV from MIA/AIS nodules with an AUC of 0.917 [0.867-0.967] on DTrain and 0.863 [0.79-0.931] on DTest. The radiomics model successfully differentiated INV from MIA cases (<1 cm AUC: 0.76 [0.53-0.98], 1-2 cm AUC: 0.92 [0.85-0.98], 2-3 cm AUC: 0.95 [0.88-1]). The final integrated model combining the classifier with the radiologists' score gave the best AUC on DTest (AUC=0.909, p<0.001). Conclusions: Addition of advanced image analysis via radiomics to the routine visual assessment of CT scans help better differentiate adenocarcinoma subtypes and can aid in clinical decision making. Further prospective validation in this direction is warranted.
RESUMO
Viral genomics has become crucial in clinical diagnostics and ecology, not to mention to stem the COVID-19 pandemic. Whole-genome sequencing (WGS) is pivotal in gaining an improved understanding of viral evolution, genomic epidemiology, infectious outbreaks, pathobiology, clinical management, and vaccine development. Genome assembly is one of the crucial steps in WGS data analyses. A series of different assemblers has been developed with the advent of high-throughput next-generation sequencing (NGS). Various studies have reported the evaluation of these assembly tools on distinct datasets; however, these lack data from viral origin. In this study, we performed a comparative evaluation and benchmarking of eight de novo assemblers: SOAPdenovo, Velvet, assembly by short sequences (ABySS), iterative De Bruijn graph assembler (IDBA), SPAdes, Edena, iterative virus assembler, and VICUNA on the viral NGS data from distinct Illumina (GAIIx, Hiseq, Miseq, and Nextseq) platforms. WGS data of diverse viruses, that is, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), dengue virus 3, human immunodeficiency virus 1, hepatitis B virus, human herpesvirus 8, human papillomavirus 16, rhinovirus A, and West Nile virus, were utilized to assess these assemblers. Performance metrics such as genome fraction recovery, assembly lengths, NG50, N50, contig length, contig numbers, mismatches, and misassemblies were analyzed. Overall, three assemblers, that is, SPAdes, IDBA, and ABySS, performed consistently well, including for genome assembly of SARS-CoV-2. These assembly methods should be considered and recommended for future studies of viruses. The study also suggests that implementing two or more assembly approaches should be considered in viral NGS studies, especially in clinical settings. Taken together, the benchmarking of eight de novo genome assemblers reported in this study can inform future public health and ecology research concerning the viruses, the COVID-19 pandemic, and viral outbreaks.

AIM: JointRep is a bioadhesive hydrogel arthroscopically injected to facilitate cartilage regeneration. The cost-effectiveness of JointRep with microfracture surgery compared to microfracture alone was evaluated from the Australian healthcare system perspective, in patients with symptomatic focal chondral defects (Outerbridge Grade 3 or 4) of the knee who had failed conservative treatment and were indicated for surgery. MATERIALS AND METHODS: A de novo Markov model comprising two health states- 'Alive' and 'Dead' was developed. Model transition probability was based on the general population mortality rates. Clinical outcomes were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, a validated patient-reported tool measuring pain, stiffness, and physical function. The utility was derived by mapping WOMAC scores to EQ-5D scores using a published algorithm. Cost inputs were based on published Australian costs from AR-DRGs, Medicare Benefits Schedule, and Prostheses List. Model outcomes included costs, Quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER). Base-case analysis was conducted for a time horizon of 3 years and a cycle length of 1 year. Cost and health outcomes were discounted at 5% per annum. Sensitivity and scenario analyses were also conducted. RESULTS: Total QALYs were estimated to be higher for JointRep with microfracture surgery (2.61) compared to microfracture surgery alone (1.66), an incremental gain of 0.95 QALY. JointRep with microfracture surgery was associated with an incremental cost of $6,022 compared to microfracture surgery alone, thus leading to an ICER of $6,328. Results were substantially robust to varying parameters in the sensitivity analyses conducted, alternative model settings and assumptions in scenario analyses. LIMITATIONS: The clinical inputs used in the model were based on data from short duration, non-randomized, post-market clinical trial. CONCLUSIONS: JointRep with microfracture surgery is a cost-effective treatment option compared to microfracture alone from the Australian health care system perspective.

Purpose: This study estimates the frequency of uninsurance for prescription drugs and cost-related medication nonadherence (CRNA) among lesbian, gay, and bisexual (LGB) persons in Canada, compared with the heterosexual population. Methods: Logistic regression was used to quantify associations between sexual orientation, insurance status, and CRNA within the national probability-based Canadian Community Health Survey, 2015-2016. This sample included 98,413 individuals aged 15-80 years, including 2803 LGB individuals. Results: From our sample of Canadians, 22.2% of LGB respondents reported being uninsured for prescription drugs, compared with 20.0% of heterosexual persons (unadjusted odds ratio [UOR] 1.14, 95% confidence interval [CI] 0.97-1.35). LGB individuals had more than twice the odds of reporting CRNA compared with heterosexual individuals (UOR 2.48, 95% CI 1.99-3.10). This disparity was most pronounced among bisexual respondents, who had over three times the odds of reporting CRNA in comparison to heterosexual respondents (UOR 3.45, 95% CI 2.65-4.51). The odds ratio (OR) for CRNA comparing bisexual with heterosexual individuals remained statistically significant after adjustment for race/ethnicity, gender/sex, and age (OR 2.67, 95% CI 1.97-3.61) and was further attenuated with adjustment for partnership status, employment status, income, educational attainment, prescription drug insurance status, general health status, and immigration status (OR 2.09, 95% CI 1.51-2.89). Conclusion: LGB Canadians reported more CRNA but comparable prescription drug insurance frequencies to heterosexual persons. Factors pertaining to medication access (e.g., income, partnership status) and health needs appear to be the most important contributors to disparities.

INTRODUCTION: Knowledge about cancer, treatment, and likely treatment outcomes is critically important for decision-making regarding adherence to the treatment. Hence, it seems imperative to find out the attitude and belief of cancer patients to determine the efficacy of cancer diagnostic and treatment available along with assessing the efficacy of prevention. The purpose of this study was to determine the level of knowledge, belief, and attitude of cancer patients who came to our facility. MATERIALS AND METHODS: The present study was a descriptive cross-sectional study which was conducted at All India Institute of Medical Sciences, Rishikesh, from July 2020 to December 2020. One hundred fifty-six newly diagnosed cancer patients were recruited. The participants were provided with a validated 44 key questionnaire divided into four different categories including the sociodemographic profile, knowledge, belief, and attitude subheading. Mean, frequency, percentage, and Chi-square test were calculated to do data analysis using SPSS version 23.0. RESULTS: Out of the total of 156 newly diagnosed cancer patients, only 130 patients provided responses so the overall response rate was 84.3%. Most of cancer patients had moderately adequate knowledge (79 [60.5%]), poor belief (111 [86%]), and neutral attitude (69 [54%]) regarding cancer. The Chi-square test revealed a link between educational level and cancer knowledge (P = 0.01). Males showed a more positive attitude than females, and this difference was statistically significant (P = 0.02). CONCLUSIONS: Cancer patients need to be made more aware of the red flag signs of cancer and improvise their attitude toward cancer. Cancer care programs should not only involve cancer patients but also involve their caregivers because the understanding of family members is of utmost importance to fight this disease.
RESUMO
AIMS: Cost-utility studies are crucial tools that help policy-makers promote appropriate resource allocation. The objective of this study was to evaluate the extent and quality of cost-utility analysis (CUA) in India through a systematic literature review. METHODS: Comprehensive database search was conducted to identify the relevant literature published from November 2009 to November 2019. Gray literature and hand searches were also performed. Two researchers independently reviewed and assessed study quality using Consolidated Health Economic Evaluation Reporting Standards checklist. RESULTS: Thirty-five studies were included in the final review. Thirteen studies used Markov model, five used decision tree model, four used a combination of decision tree and Markov model and one each used microsimulation and dynamic compartmental model. The primary therapeutic areas targeted in CUA were infectious diseases (n = 12), ophthalmology (n = 5), and endocrine disorders (n = 4). Five studies were carried out in Tamil Nadu, four in Goa, three in Punjab, two each in Delhi, Maharashtra, and Uttar Pradesh, and one each in West Bengal and Karnataka. Twenty-three, eight, and four studies were found to be of excellent, very good, and good quality, respectively. The average quality score of the studies was 19.21 out of 24. CONCLUSIONS: This systematic literature review identified the published CUA studies in India. The overall quality of the included studies was good; however, features such as subgroup analyses and explicit study perspective were missing in several evaluations.
RESUMO
BACKGROUND: Peritoneal dialysis (PD) as a modality of kidney replacement therapy (KRT) is largely underutilized globally. We analyzed PD utilization, impact of economic status, projected growth and impact of state policy(s) on PD growth in South Asia and Southeast Asia (SA&SEA) region. METHODS: The National Nephrology Societies of the region responded to a questionnaire on KRT practices. The responses were based on the latest registry data, acceptable community-based studies and societal perceptions. The representative countries were divided into high income and higher-middle income (HI & HMI) and low income and lower-middle income (LI & LMI) groups. RESULTS: Data provided by 15 countries showed almost similar percentage of GDP as health expenditure (4%-7%). But there was a significant difference in per capita income (HI & HMI -US$ 28 129 vs. LI & LMI - US$ 1710.2) between the groups. Even after having no significant difference in monthly cost of haemodialysis (HD) and PD in LI & LMI countries, they have poorer PD utilization as compared to HI & HMI countries (3.4% vs. 10.1%); the reason being lack of formal training/incentives and time constraints for the nephrologist while lack of reimbursement and poor general awareness of modalities has been a snag for the patients. The region expects ≥10% PD growth in the near future. Hong Kong and Thailand with 'PD first' policy have the highest PD utilization. CONCLUSION: Important deterrents to PD underutilization were lack of PD centric policies, lackadaisical patient/physician's attitude, lack of structured patient awareness programs, formal training programs and affordability.

Protein-peptide interactions are involved in many fundamental cellular functions and constitute promising drug targets. Here, we provide a detailed protocol for the cost-effective preparation of a cellulose-based solid support for synthesis of nanoscale to micromolar-scale peptide libraries. Their subsequent use for high-throughput protein interaction screening as well as affinity determination in solution provides binding data for thousands of unique peptides with a turnover of 1 to 2 weeks, thereby facilitating in vitro assessment and development of high-affinity binders. For complete details on the use and execution of this protocol, please refer to Schulte et al., (2020).

BACKGROUND: In India, the mortality due to polytrauma after road traffic injuries is high and there is a need to train medical and paramedical personnel. The AIIMS Trauma Assessment and Management (ATAM) course was developed at the Apex Trauma Centre of All India Institute of Medical Sciences, New Delhi to sensitize medical personnel with initial assessment and management of polytrauma victims. The aim of this study was to evaluate the impact on knowledge and skills and also evaluate the feedback and the perception of the participants of the ATAM course. METHODS: The course was conducted for doctors, nurses and other paramedical/allied professionals in five tertiary level centres associated to medical colleges from geographically diverse locations (Anand, Bengaluru, Delhi, Lucknow and Thrissur). Cognitive knowledge was assessed using pre-training and post-training multiple choice question (MCQ) tests. The participants also self-rated their level of knowledge, skill, confidence and capability (Numerical rating scale of 1-10). Post-training feedback was obtained from the participants using a five-point Likert scale response. RESULTS: 26 ATAM courses were conducted by 68 course instructors and attended by 780 participants. These participants include 40.4% doctors, 44.2% nurses, 4.7% paramedical technicians, 4.2% medical students and 6.4% paramedical and allied health professionals. There was significant improvement (p < 0.0001) in the cognitive knowledge, skill, confidence and capability of the participants. 85%-86% of the participants strongly agreed or agreed that the course content was effective and 85% of participants perceived that the course was excellent or very good. CONCLUSION: The ATAM course had a positive impact on the knowledge, skills, confidence and capability of health caregivers attending the course. The ATAM course is an effective, practical and favourable option that is tailored to the polytrauma training needs of India. We recommend widespread dissemination of this course.
RESUMO
Background: With the emergence of the COVID-19 pandemic, most health-care personnel and resources are redirected to prioritize care for seriously-ill COVID patients. This situation may poorly impact our capacity to care for critically injured patients. We need to devise a strategy to provide rational and essential care to hand trauma victims whilst the access to theatres and anaesthetic support is limited. Our center is a level 1 trauma center, where the pandemic preparedness required reorganization of the trauma services. We aim to summarise the clinical profile and management of these patients and highlight, how we modified our practice to optimize their care. Methods: This is a single-centre retrospective observational study of all patients with hand injuries visiting the Department of Plastic Surgery from 22nd March to 31st May 2020. Patient characteristics, management details, and outcomes were analysed. Results: A total of 102 hand injuries were encountered. Five patients were COVID-19 positive. The mean age was 28.9 ± 14.8 years and eighty-two (80.4%) were males. Thirty-one injuries involved fractures/dislocations, of which 23 (74.2%) were managed non-operatively. Seventy-five (73.5%) patients underwent wound wash or procedure under local anaesthetic and were discharged as soon as they were comfortable. Seventeen cases performed under brachial-plexus block, were discharged within 24 hours except four cases of finger replantation/ revascularisation and one flap cover which were discharged after monitoring for four days. At mean follow-up of 54.4 ± 21.8 days, the rates of early complication and loss to follow-up were 6.9% and 12.7% respectively. Conclusions: Essential trauma care needs to continue keeping in mind, rational use of resources while ensuring safety of the patients and health-care professionals. We need to be flexible and dynamic in our approach, by utilising teleconsultation, non-operative management, and regional anaesthesia wherever feasible.

Coercive pressure has forced firms to take up environmental measures in the last two decades in emerging economies. Under normative pressure, large firms with farsightedness take up the environmental practices as industry leaders. In a little mature emerging economy, such as India, where triple bottom line awareness is growing, the government facilitates the firms to operate in an environment-friendly ecosystem. We investigate how do environmental compliance and environmental practices influence the overall firm performance? The performance was measured in terms of financial, customer, internal business process, and learning and growth performance. A survey instrument was designed using well-established scales and administered to the middle to top-level corporate management executives to gather 240 data from the Indian firms. A rigorous statistical validity, diagnostics, and SEM were used to test the hypotheses. The environmental practices showed a full mediation effect on the effect of environmental compliance on performance. The examination of mediation relationships in an environmental context is limited in the reported literature. This paper is among the initial works that deal with complicated mediation relationships drawn from institutional theory propositions. The study established and argued that environmental practices' ecosystem would turn firms towards voluntary environmental compliance and eventually enjoy the long-term performance.
RESUMO
BACKGROUND: Conventional CTCS images the mid/lower chest for coronary artery disease (CAD). Because many CAD patients are also at risk for lung malignancy, CTCS often discovers incidental pulmonary nodules (IPN). CTCS excludes the upper chest, where malignancy is common. Full-chest CTCS (FCT) may be a cost-effective screening tool for IPN. METHODS: A decision tree was created to compare a FCT to CTCS in a hypothetical patient cohort with suspected CAD. (Figure) The design compares the effects of missed cancers on CTCS with the cost of working up non-malignant nodules on FCT. The model was informed by results of the National Lung Screening Trial and literature review, including the rate of malignancy among patients receiving CTCS and the rate of malignancy in upper vs lower portions of the lung. The analysis outcomes are Quality-Adjusted Life Year (QALY) and incremental cost-effectiveness ratio (ICER), which is generally considered beneficial when <$50,000/QALY. RESULTS: Literature review suggests that rate of IPNs in the upper portion of the lung varied from 47 to 76%. Our model assumed that IPNs occur in upper and lower portions of the lung with equal frequency. The model also assumes an equal malignancy potential in upper lung IPNs despite data that malignancy occurs 61-66% in upper lung fields. In the base case analysis, a FCT will lead to an increase of 0.03 QALYs comparing to conventional CTCS (14.54 vs 14.51 QALY, respectively), which translates into an QALY increase of 16 days. The associated incremental cost for FCT is $278 ($1027 vs $748, FCT vs CTCS respectively. The incremental cost-effectiveness ratio (ICER) is $10,289/QALY, suggesting significant benefit. Sensitivity analysis shows this benefit increases proportional to the rate of malignancy in upper lung fields. CONCLUSION: Conventional CTCS may be a missed opportunity to screen for upper lung field cancers in high risk patients. The ICER of FCT is better than screening for breast cancer screening (mammograms $80 k/QALY) and colon cancer (colonoscopy $6 k/QALY). Prospective studies are appropriate to define protocols for FCT.
