    Primary hepatic leiomyosarcoma is an extremely rare tumor with a dismal prognosis and difficulty in diagnosis. We present a 36-year-old female who presented with complaints of pain in right hypochondrium and epigastric region. Real-time ultrasonography revealed an enlarged liver with multiple hypoechoic lesions of varying sizes in both the lobes of the liver. USG guided core biopsy from the lesion showed an infiltrating malignant spindle cell neoplasm positive for smooth muscle actin and caldesmon-H confirming the diagnosis of leiomyosarcoma. It is vital to diagnose these lesions even on limited biopsies as early diagnosis can reduce hospital and operative morbidity and mortality rates in the patients

    Importance: To our knowledge, thyroid cancer incidence is increasing faster than any other cancer type and is currently the fifth most common cancer among women. While this rise is likely multifactorial, there has been scarce consideration of the effect of insurance statuses on the treatment of thyroid cancer. Objective: We evaluate the association of insurance expansion with thyroid cancer treatment using the 2006 Massachusetts health reform, which serves as a unique natural experiment. Design, Setting, and Participants: We used the Agency for Healthcare Research and Quality State Inpatient Databases to identify patients with government-subsidized or self-pay insurance or private insurance who were admitted to a hospital with thyroid cancer and underwent a thyroidectomy between 2001 and 2011 in Massachusetts (n = 8534) and 3 control states (n = 48 047). Difference-in-differences models were used to evaluate an association between the 2006 Massachusetts health care reform and thyroid cancer treatment, and participants were controlled for age, sex, comorbidities, and secular trends. Main Outcomes and Measures: Change in the thyroidectomy rate for thyroid cancer treatment was the primary outcome evaluated. Results: The Massachusetts cohort consisted of 6443 women (75.5%) and 2091 men (24.5%), of whom 6388 (79.6%) were white, 391 (4.9%) were black, 527 (6.6%) were Hispanic, 424 (5.3%) were Asian/Pacific Islander, 63 (0.8%) were Native American, and 228 (2.8%) were other. The participants from control states included 36 818 women (76.6%) and 11 229 men (23.4%), of whom 30 432 (65.5%) were white, 3818 (8.2%) were black, 6462 (13.9%) were Hispanic, 2591 (5.6%) were Asian/Pacific Islander, 211 (0.5%) were Native American, and 2947 (6.3%) were other. Before the 2006 Massachusetts insurance expansion, patients with government-subsidized or self-pay insurance had lower thyroidectomy rates for thyroid cancer in Massachusetts and the control states compared with patients with private insurance. The Massachusetts insurance expansion was associated with a 26% increased rate of undergoing a thyroidectomy (incident rate ratio, 1.26; 95% CI, 1.04-1.52; P = .02) and a 22% increased rate of neck dissection (incident rate ratio, 1.22; 95% CI, 1.07-1.37; P = .002) for treating cancer compared with control states. Conclusions and Relevance: The 2006 Massachusetts health reform, which is a model for the Affordable Care Act, was associated with a 26% increased rate of thyroidectomy for treating thyroid cancer. Our study suggests that insurance expansion may be associated with increased access to the surgical management of thyroid cancer. Further studies need to be conducted to evaluate the effect of healthcare expansion at a national level

    Background: Teaching surgical skills in the simulation lab has increased markedly compared to teaching only in the operating room. Although many studies have been performed investigating the optimal teaching methodology for skills acquisition, there is no consensus on the best method. Massed and distributed practices are important methods in teaching procedural skills. Considering the limited human and logistical resources in low and middle-income settings, it is valuable to understand the optimal methodology for learning and acquiring surgical skills. Methods: Thirty-two core needle biopsy-naïve first-year residents and final year medical students rotating in general surgery were enrolled in and completed the study at University Teaching Hospital of Kigali, a tertiary, teaching and referral hospital in Kigali, Rwanda. They were assigned to a “massed” group (i.e., one time, 3-hour practice) or “distributed” group (i.e., 1-hour practice per week for 3 weeks). Trainees were taught ultrasound-guided core needle biopsy on a high-fidelity breast simulator. All participants completed pre- and post-tests and an evaluation of skill retention was performed one month after completion of the training. Analysis of performance was completed, and p-value ≤ 0.05 was considered statistically significant. Results: There was no difference between performance on the pretest (p=0.985) and the posttest (p=0.680). Both groups demonstrated improvement after implementation of the simulation training when comparing pretest and posttest results (p<0.001); there were no differences in the evaluation of skills retention after one month after the training between the two groups (p=0.273). Conclusions: The results of this study demonstrate that both groups have improved significantly their knowledge and skills. Trainees have similar retention of skills in ultrasound guided core needle biopsy on a breast simulator whether trained under a massed or distributed practice schedule. Both methods may be considered in our setting for teaching surgical skills. Keywords: surgical simulation; resource-limited setting; global surgery

    Background: There is a paucity of data to assess the impact of the COVID-19 pandemic on persons with disabilities (PwDs) in India. About 27.4 million cases were reported as of 27 May 2021. The continuing pandemic in the form of subsequent waves is expected to have negative repercussions for the disabled globally, particularly in India, where access to health, rehabilitation, and social care services is very limited. Therefore, this study aimed to assess the impact of the COVID-19 pandemic and lockdown restrictions on PwDs in India. Objective: To determine the level of disruption due to COVID-19 and the associated countrywide lockdown restrictions on PwD in India during the first wave. Methods: Using a cross-sectional, mixed-methods approach, data were collected from a representative sample of 403 persons with disabilities in 14 states in India during the COVID-19 first wave at two different points in time (Lockdown and post-lockdown phase). Factors associated with the negative impact were examined using the Chi-square test for associations. The paired comparisons between ‘lockdown’ with the ‘post-lockdown’ phase are presented using McNemar’s test and the marginal homogeneity test to compare the proportions. Additionally, a subsample of the participants in the survey was identified to participate in in-depth interviews and focus group discussions to gain in-depth insights on the study question and substantiate the quantitative findings. The framework approach was used to conduct a thematic analysis of the qualitative data. Results: About 60 of the PwDs found it difficult to access emergency medical services during the lockdown, and 4.6 post lockdown (p < 0.001). Likewise, 12 found it difficult to access rehabilitation services during the lockdown, and 5 post lockdown (p = 0.03). About 76 of respondents were apprehensive of the risk of infection during the lockdown, and this increased to 92 post lockdown (p < 0.001). Parents with children were significantly impacted due to lockdown in the areas of Medical (p = 0.007), Rehabilitation (p = 0.001), and Mental health services (p = 0.001). The results from the qualitative study supported these quantitative findings. PWDs felt that the lockdown restrictions had negatively impacted their productivity, social participation, and overall engagement in everyday activities. Access to medicines and rehabilitation services was felt to be extremely difficult and detrimental to the therapeutic benefits that were gained by them during the pre-pandemic time. None of the pandemic mitigation plans and services was specific or inclusive of PWDs. Conclusions: COVID-19 and the associated lockdown restrictions have negatively impacted persons with disabilities during the first wave in India. It is critical to mainstream disability within the agenda for health and development with pragmatic, context-specific strategies and programs in the country

    This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.Objective: To determine the relationship between interventricular septal position (SP) and right ventricular systolic pressure (RVSP) and mortality in infants with severe BPD (sBPD). Study design: Infants with sBPD in the Children's Hospitals Neonatal Database who had echocardiograms 34-44 weeks' postmenstrual age (PMA) were included. SP and RVSP were categorized normal, abnormal (flattened/bowed SP or RVSP > 40 mmHg) or missing. Results: Of 1157 infants, 115 infants (10%) died. Abnormal SP or RVSP increased mortality (SP 19% vs. 8% normal/missing, RVSP 20% vs. 9% normal/missing, both p < 0.01) in unadjusted and multivariable models, adjusted for significant covariates (SP OR 1.9, 95% CI 1.2-3.0; RVSP OR 2.2, 95% CI 1.1-4.7). Abnormal parameters had high specificity (SP 82%; RVSP 94%), and negative predictive value (SP 94%, NPV 91%) for mortality. Conclusions: Abnormal SP or RVSP is independently associated with mortality in sBPD infants. Negative predictive values distinguish infants most likely to survive

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Development and standardization of Mysore Tridosha scale

    No full text
    The authors have developed a personality scale to assess Tridoshas i.e. Vata, Pitta, and Kapha from psychological perspective in human beings. The Tridoshas are composed of the Pancha Mahabhutas, but one or the other Dosha is dominant singularly or in combination. There can never be a state when one or the other Pancha Mahabhutas and consequently the Tridoshas are absent totally. All five are essential to sustain life. Vata Dosha is composed of Akasa and Vayu Mahabhuta. Pitta Dosha is composed of Tejas or Agni and Ap Mahabhuta. Kapha Dosha is composed of Ap and Prithvi Mahabhuta. Although Tridosha is studied, understood, and applied in Ayurveda, the present authors have tried to validate the same from the domain of psychology. Since the authors are not from the domain of Ayurveda but of Psychology, there are some constructs that are not amenable for psychological testing which have been ignored. Only those constructs that can be used by psychologists to assess the psychological aspects of the Dosha Prakriti have been used to build items for the assessment of personality. In this process, the psychometric properties of the scale are established. The scale assesses the psychological manifestation of the Tridoshas, which was the basic objective. The standardization procedure involved in the development of the Mysore Psychological Tridosha Scale is herewith delineated

    Understanding personality from Ayurvedic perspective for psychological assessment: A case

    The study of personality has fascinated psychologists since a long time. Personality as an area of study has grown so much that a wealth of literature is available. On the other hand, the socio-ethnic dynamics of human race in the emerging global village context provoking psychologists to develop a personality theory which can treat certain basic components of personality as invariants, so that irrespective of culture, race, and nativity could still be able to study personality which will have universal applicability and relevance, is still far away. In the above emerging backdrop, “Ayurveda” has perhaps an important role to play as it can enable providing a theoretical and empirical base of personality traits and types. These Ayurvedic concepts are applicable to all human beings irrespective of caste, color, sex or race. Therefore, it is interesting to build on the Ayurvedic knowledge which has already given us so much since time immemorial, and validate some of these issues related to personality from psychological perspective. There are already certain efforts in understanding Sattva, Rajas, and Tamas Gunas. It can be furthered so that a comprehensive personality picture can be generated, which can have implications for health, career, education and many other dimensions of life. The present paper is a theoretical attempt in developing such a personality proposition which can be validated. Thus, the present paper only builds a theoretical framework for their possible empirical validity

    Extended Target Localization Using the Variational Garrote

    No full text
    In several high-resolution array processing applications such as radar and sonar, it is necessary to localize targets that have a finite angular spread. In such scenarios, conventional subspace-based techniques tend to provide erroneous results, and hence, an extended target model is more appropriate. In this work, we consider a multiple input multiple output system model and propose to jointly estimate the range, Doppler shift and angular spread of extended targets. More specifically, we show that the extended nature of the target leads to a block-sparse recovery problem. To solve the problem, we present an extension of the variational Garrote method to estimate the unknown block sparse vector. The variational Garrote provides a simple approach for direct feature subset selection via a variational approximation to the posterior distribution over the subsets. In addition, our proposed method also takes into account the scaling of the angular spread of the target(s) at different distances. We illustrate the efficacy of our approach using Monte Carlo simulations
