Growth performance, meat quality and hematological parameters of broiler chickens fed safflower seed.

The aim of the current study was to determine the effects of dietary supplementation of safflower seed (SS) on the growth performance and hematological parameters of broiler birds along with the physicochemical, textural and sensory attributes of chicken meat. A total of 200 male chickens (7-days-old) were distributed into 5 groups (40 chickens in each) with 5 replicates of 8 chicks in a 42-day experiment. Each group was allocated to one of 5 dietary treatments, i.e., 0, 2.5, 5, 7.5, and 10% SS. The experimental diets were formulated for starter (7 to 21 days) and finisher (22 to 42 days) phases. Inclusion of SS in the diet improved growth performances in treatment groups between 7 and 42 days. The highest and lowest body weights were observed at the 5% SS and 0% SS levels, respectively. The physicochemical attributes of breast and thigh meat were found (P > 0.05) except for crude fat. The crude fat was significantly (P < 0.05) increased with increasing levels of SS in the diet. The inclusion of SS in the diet did not negatively impact the textural properties, i.e., hardness, cohesiveness, springiness, gumminess, chewiness, and shear force of breast and thigh meat. There was no significant difference in the sensory parameters of cooked chicken meat with increasing levels of SS in the diet. The results demonstrated a significant (P < 0.01) improvement in hematological parameters in the blood samples of broiler chickens fed diet supplemented with various levels of SS for five weeks. These findings suggest that, SS may be used as an oil seed for broiler chicken feed.

Comparing T2-T3 staging of penile cancer according to the American Joint Committee on cancer 8th edition with two modified staging systems in predicting survival outcome: A single-center experience.

Introduction: Penile cancer is a rare malignancy of the genitourinary tract. We aimed to validate the recent changes in the T2 and T3 stages of penile cancer in the American Joint Committee on Cancer (AJCC) 8th edition and to compare its predictive ability with two other modified staging systems for survival outcomes. Methods: This is a retrospective study of patients diagnosed with penile cancer from June 2015 to March 2020. The AJCC 8th edition and two other newly proposed systems by Li et al. and Sali et al. were used for staging the tumor. All variables were categorized and correlated with lymph node (LN) metastases and overall survival (OS). Results: Fifty-four patients were eligible for this study. The mean age was 58 years (range 46-72 years). The tumor stage (P = 0.016), clinical LN stage (P = 0.001), the involvement of the spongiosa (P = 0.015) and the cavernosa (P = 0.002), lymphovascular invasion (LVI) (P = 0.000), and PNI (P = 0.021) were found to be the significant predictors of LN metastases. When the 5 year OS was compared between the T2 and T3 stages of the AJCC 8th edition, Li staging and the Sali staging systems, it was 91% and 50.1% (P = 0.001), 97.5% and 10.3% (P = 0.000), 94.4% and 14.7% (P = 0.000), respectively. The presence of LVI (P = 0.001) was the most significant independent predictor of OS. Conclusions: The recent changes in the AJCC 8th edition pertaining to the T2-T3 stage are relevant, although the other two newly proposed staging systems were more precise in predicting the survival outcomes.

Upper tract transitional cell carcinoma clinically mimicking inflammatory renal pathology: A report of three cases.

Upper tract urothelial carcinoma (UTUC) of the renal pelvis and the ureter is incidentally detected in a small proportion of cases. However, the majority of UTUC cases present with hematuria, flank pain, and clot colic. Typical imaging features include hydronephrosis of the kidney (s) due to obstruction by the mass with a soft-tissue lesion that typically shows low-grade enhancement with or without a filling defect. Rarely, such a tumor may present with signs and symptoms mimicking an inflammatory or infective pathology of the kidney and is diagnosed only on biopsy or on nephrectomy. We present three such patients and cite another similar case we have published earlier. All three of these patients presented with signs and symptoms of an obstructed infected kidney with long-standing renal calculi and a forgotten DJ stent in one instance. Nephrectomy for the presumed infected kidney in all three cases revealed high-grade UTUC. In patients presenting with equivocal findings on cross-sectional imaging with a history of renal calculi or foreign bodies, we should have a high index of suspicion for malignancy.

Role of positron emission tomography/computed tomography in the evaluation of renal cell carcinoma.

INTRODUCTION: Positron emission tomography (PET) is not a standard recommendation in most of the major guidelines for the evaluation of renal cell carcinoma (RCC). Earlier studies evaluating PET scan in patients with RCC have provided discordant results. However, with the advent of newer hybrid PET/computed tomography (CT) scanning systems, this modality has shown increased efficacy in the evaluation of primary renal masses along with the detection of extrarenal metastases, restaging recurrent RCC, and also in monitoring response to targeted therapy. We performed a systematic review of the existing literature on the role of PET scan in the evaluation of RCC. METHODOLOGY: We systematically searched the databases of PubMed/Medline, Embase, and Google Scholar to identify studies on the use of PET scan in RCC. Using Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, 94 full-text articles were selected, of which 54 relevant articles were then reviewed, after a consensus by the authors. RESULTS: Several studies have shown similar sensitivity and specificity of fluoro-2-deoxy-2-d-glucose-PET (FDG-PET) scan as compared to conventional CT scan for the initial diagnosis of RCC, and an improved sensitivity and specificity for the detection of metastases and recurrences following curative therapy. The PET scan may also play a role in predicting the initial tumor biology and pathology and predicting the prognosis as well as the response to therapy. CONCLUSION: The current guidelines do not recommend PET scan in the staging armamentarium of RCCs. However, FDG-PET scan is as efficacious, if not better than conventional imaging alone, in the evaluation of the primary and metastatic RCC, as well as in evaluating the response to therapy, due to its ability to pick up areas of increased metabolic activity early on. Newer tracers such as Ga68 prostate specific membrane antigen-labeled ligands may help in opening up newer avenues of theragnostics.

Experience with management of renal cell carcinoma with inferior vena cava/right atrial tumor thrombus.

INTRODUCTION: We aimed to present our experience in managing renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombus. METHODS: Records of all patients aged 18 years and older, with a diagnosis of primary renal masses with IVC thrombus, presenting to our institute from January 2012 to August 2020 were retrospectively reviewed. Patients with tumor thrombus limited only to renal vein were excluded from the analysis. Their hospital course and outcomes were recorded and evaluated for predictors of survival. RESULTS: During the study period, we treated 61 patients with a renal mass and concurrent IVC thrombus and 56 of these underwent surgery. 7 of them had level III and 6 had level IV thrombus. A total of six patients received neoadjuvant tyrosine kinase inhibitor (TKI) therapy and all of them showed a decrease in size and level of tumor thrombus and cardiopulmonary bypass was safely avoided. Fourteen patients had distant metastasis and underwent cytoreductive surgery and of these 12 patients received TKI therapy after surgery with a mean survival of 26.8 months. The overall survival at 2 and 5 years of nonmetastatic group was 81.1% and 47.5% respectively and in metastatic group was 35.1% and 0%, respectively. Poor performance status, distant metastasis, higher T stage, higher thrombus levels, and positive surgical margins were all predictors of decreased survival. CONCLUSIONS: Complete surgical resection in both nonmetastatic and metastatic RCC with IVC thrombus has long-term survival benefits. Neoadjuvant TKI therapy, with adequate preoperative planning, helps in decreasing the size of the thrombus and in safely avoiding bypass in level III and IV IVC thrombi.

Symmetry breaking dynamics induced by mean-field density and low-pass filter.

The phenomenon of spontaneous symmetry breaking facilitates the onset of a plethora of nontrivial dynamical states/patterns in a wide variety of dynamical systems. Spontaneous symmetry breaking results in amplitude and phase variations in a coupled identical oscillator due to the breaking of the prevailing permutational/translational symmetry of the coupled system. Nevertheless, the role and the competing interaction of the low-pass filter and the mean-field density parameter on the symmetry breaking dynamical states are unclear and yet to be explored explicitly. The effect of low pass filtering along with the mean-field parameter is explored in conjugately coupled Stuart-Landau oscillators. The dynamical transitions are examined via bifurcation analysis. We show the emergence of a spontaneous symmetry breaking (asymmetric) oscillatory state, which coexists with a nontrivial amplitude death state. Through the basin of attraction, the multi-stable nature of the spontaneous symmetry breaking state is examined, which reveals that the asymmetric distribution of the initial state favors the spontaneous symmetry breaking dynamics, while the symmetric distribution of initial states gives rise to the nontrivial amplitude death state. In addition, the trade-off between the cut-off frequency of the low-pass filter along with the mean-field density induces and enhances the symmetry breaking dynamical states. Global dynamical transitions are discussed as a function of various system parameters. Analytical stability curves corresponding to the nontrivial amplitude death and oscillation death states are deduced.

Role of preoperative MR volumetry in patients with renal cell carcinoma for prediction of postoperative renal function after radical nephrectomy and nephron sparing surgery.

PURPOSE: Preoperative computed tomography or magnetic resonance (MR) imaging are commonly used for radiological evaluation of renal cell carcinoma (RCC) before radical nephrectomy or nephron sparing surgery(NSS). This study aimed to assess the role of MRI for predicting postoperative renal function by preoperative estimation of renal parenchymal volume and correlation with glomerular fi ltration rate (GFR). MATERIALS AND METHODS: A prospective observational study was conducted from February 2015 to October 2016 at a tertiary care hospital in northern India. MR imaging was done on 3 Tesla MR scanner (Signa Hdxt General Electrics, Milwaukee, USA). MR volumetry was used to estimate the renal parenchymal volume. GFR was measured in all patients using Tc99m Diethyl-triamine-penta-acetic acid using Russell's algorithm. Such measurement was done preoperatively, and postoperatively 3 months after surgery. RESULTS: 30 patients with suspected RCC underwent NSS (n=10) and radical nephrectomy (n=20). Median tumour volume was 175.7cc (range: 4.8 to 631.8cc). The median volume of the residual parenchyma on the affected side was 84.25±41.97cc while that on the unaffected side was 112.25±26.35cc. There was good correlation among the unaffected kidney volume and postoperative GFR for the radical nephrectomy group (r=0.83) as well as unaffected kidney volume, total residual kidney volume and residual volume of affected kidney with postoperative GFR for the NSS group (r=0.71, r=0.73, r=0.79 respectively; P<0.05). CONCLUSION: Preoperative residual parenchymal volume on MR renal volumetry correlates well with postoperative GFR in patients with RCC undergoing radical nephrectomy or NSS.

Radical cystectomy and W-shaped ileal orthotopic neobladder reconstruction with serosa-lined tunneled ureteroileal anastomoses: A critical analysis of the short-term voiding patterns and urodynamic and functional outcomes.

INTRODUCTION: We present the short-term voiding patterns and functional and urodynamic outcomes of W-shaped ileal orthotopic neobladder (ONB) following radical cystectomy (RC). MATERIALS AND METHODS: Forty-one patients who underwent RC and W-shaped ONB creation between July 2015 and January 2018 were enrolled. Data were analyzed in terms of voiding patterns, urodynamic findings, and functional outcomes at 6 months after surgery. Pouch-related quality of life (QoL) was assessed using European Organization for Research and Treatment of Cancer (EORTC) Generic (QLQ C30), Bladder Cancer-Specific Instruments (QLQ BM30), and IONB-Patient-Reported Outcome (IONB-PRO). RESULTS: The mean length of follow-up was 19.4 months. At first follow-up, three patients had developed acidosis and rising serum creatinine, and one of them required temporary hemodialysis. One patient developed urethral-pouch anastomotic stricture, which required bladder neck incision. Balloon dilatation was performed for ureteroileal anastomotic stricture and mesh repair for incisional hernia was required in one patient each. Upper tract changes were observed in two patients. During the first and second follow-up, maximum flow rate, voided volume, and postvoid residual urine were 12 ± 4.7 mL/s, 212 ± 120 mL, and 72 + 81 mL and 14.7 ± 5.3 mL/s, 254 ± 168 mL, and 123.7 ± 42.5 mL, respectively. The mean pouch capacity and compliance were 436 ± 103.5 mL and 50.6 ± 17.8 mL/cm H2O. No patient required clean intermittent catheterization for bladder emptying. In EORTC QLQ-C30 questionnaire, the "Cognitive" domain had the highest and "global QoL" domain had the lowest level of functional scores. "Nausea and vomiting and abdominal bloating and flatulence" domain had the lowest level and "financial difficulties and urinary symptoms" had the highest level of symptomatology in EORTC QLQ questionnaire. The IONB-PRO questionnaire showed the highest level of functioning in "relation life" and the lowest level in "emotional life" domain. CONCLUSION: The Ghoneim pouch has a low complication rate with near-normal voiding patterns with an acceptable QoL impairment.

Safety and outcome of percutaneous nephrolithotomy in patients with solitary kidney: A tertiary care center experience.

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) for stones in solitary kidney poses a significant challenge and potential threat for acute kidney injury or progression of chronic kidney disease (CKD). We present our experience of PCNL in solitary functioning kidney (SFK) to evaluate the safety, efficacy, and postoperative complications and highlight the differences between these outcomes with respect to the stage of CKD. METHODS: We carried out a retrospective study of patients with SFK, who underwent PCNL at our center from April 2010 to March 2018. Patients who had a minimum of 6 months of follow-up were included. Patients were classified into CKD groups based on the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative. Group 1 included Stages 1, 2, and 3A and Group 2 included Stages 3B, 4, and 5. Postoperative complications and stone-free rate were recorded and graded according to the Clavien-Dindo classification and compared between the two groups. RESULTS: We had a total of 128 patients (Group 1 - 84 and Group 2 - 44). Stone-free rate after the first PCNL was higher in Group 1 as compared to Group 2 (88.1% [n = 74] vs. 50% [n = 22], P = 0.02). Overall, 48 patients (37.5%) had postoperative complications, but most were minor. Clavien Grade 1 and 2 complications were seen in 34 patients (Group 1, n = 18 and Group 2, n = 16, P = 0.069), whereas Grade 3 and 4 complications were seen in 14 patients (Group 1, n = 2 and Group 2, n = 12, P < 0.001), respectively. Need for postoperative (number of sessions) dialysis was seen with increased frequency in patients with higher chronic kidney stages (Group 1 vs. Group 2; 6 vs. 22 sessions, P < 0.001). CONCLUSION: PCNL in SFK is safe, with satisfactory outcome, but patients with advanced CKD stage have higher risk of complications including need for dialysis and may require multiple sessions for complete stone clearance. Hence, they should be managed at high output tertiary centers.

A retrospective analysis of complications of laparoscopic left donor nephrectomy using the Kocak's modification of Clavien-Dindo system.

INTRODUCTION: Kocak described a modification of Clavien-Dindo classification system (CDCS) for reporting procedure-related complications in laparoscopic donor nephrectomy (LDN). We used the Kocak modification in grading and reporting the severity of complications in patients who underwent LDN and in evaluating various parameters that predict them. METHODS: In all, 1430 patients who underwent left LDN from 2000 to 2016 were included in this study. All data was retrospectively collected and analyzed for complications occurring in the postoperative period. All complications were classified according to the four grades of Kocak-modified CDCS. RESULTS: 124 patients (8.6%) suffered a total of 235 postoperative complications. Most of the complications were Grade I and Grade II (Grade I: 79.5% [n = 187] and Grade II 16.2% [n = 38]), 2.5% of the complications were Grade III (n = 6) and Kocak Grade IVa complications occurred in three patients. There was one death (Grade IVb: 0.4%, overall mortality rate: 0.06%). The incidence of complications was significantly greater for male patients, those with body mass index ≥25 kg/m2, and if the operating surgeon had ≤ 1 year of experience in performing LDN surgery. CONCLUSION: LDN is a safe procedure with low morbidity. The rate of complications is 8.6% and most of these complications are of low grade. The use of a standardized system for reporting the complications of LDN allows appropriate comparison between reported data.

Developing and pilot testing of a tool for "clinicosocial case study" assessment of community medicine residents.

BACKGROUND: Practical and clinical skills teaching should constitute a core part of the postgraduate curriculum of Community Medicine. The clinicosocial case study is a method to enhance learners' skills but there is no generally accepted organized system of formative assessment and structured feedback to guide students. A new tool based on the principles of mini-Clinical Evaluation Exercise (mini CEX) was developed and pilot tested as a 'clinicosocial case study' assessment of community medicine residents with feedback as a core component. METHODS: Ten core domains of clinicosocial skills were identified after reviewing the relevant literature and input from local experts in community medicine and medical education. We pilot tested the tool with eight faculty members to assess five residents during clinicosocial case presentations on a variety of topics. Kappa statistic and Bland Altman plots were used to assess agreement between faculty members' average assessment scores. Cronbach's alpha was used to test the internal consistency with faculty members as domains. RESULTS: All 95% confidence limits using the Bland-Altman method were within the predetermined limit of 2 points. The overall Kappa between two faculty members was fair ranging from 0.2 to 0.3. Qualitative feedback revealed that both faculty and residents were enthusiastic about the process but faculty suggested further standardization, while residents suggested streamlining of the process. DISCUSSION: This new assessment tool is available for objective and unbiased assessment of residents through 'clinicosocial case study,' which enriches learning through comprehensive feedback. Further validation in different settings is needed.

Spatial mapping of focused surface acoustic waves in the investigation of high frequency strain induced changes.

The field of straintronics, in which strain is used to drive phase transitions, ordering and structural changes, has conventionally been limited to dc or low frequency strain. High frequency large strains, which have the potential to serve as a high frequency trigger of strain sensitive physical phenomena, can be generated using focused surface acoustic waves, which produce two dimensional standing strain waves with very high strain at the elliptical focus. Here, the strain standing wave pattern generated by a focused surface acoustic wave is mapped and quantified as a function of voltage and frequency with high spatial resolution. A knife-edge optical reflection method is used to map the strain standing wave pattern generated by a 87.95 MHz annular interdigital transducer on 128° Y-Cut LiNbO3. Subsequent to strain mapping, ferromagnetic Co/Pt multilayers nanostructures are lithographically patterned within the high strain region for preliminary measurements of magnetization changes arising from high frequency fast strain. The knife edge technique is simple, results in excellent spatial resolution and is fully compatible with other optical measurements, such as focused magneto-optic Kerr measurements, while maintaining spatial information. This ability to accurately and reproducibly determine the position of maximum strain and to lock onto a specific strain region is an important step in the investigation of the effects of high frequency strain on thin film materials, which range from magnetic reorientations to strain induced phase transitions.

Interaction between dopamine and neuropeptide Y in the telencephalon of the Indian major carp, Cirrhinus cirrhosus.

In teleosts, while neuropeptide Y (NPY) has emerged as one of the potent regulators of GnRH-LH axis, entopeduncular nucleus (EN) in the ventral telencephalon serves as major site for NPY synthesis/storage. Neurons of the EN innervate preoptic area and pituitary, respond to gonadal steroids, undergo reproduction phase-related changes, and are believed to convey sex steroid-borne information to GnRH neurons. In spite of the importance of EN, the neural circuitry associated with the nucleus has not been defined. Aim of the present study is to examine the possibility of the dopaminergic regulation of EN. NPY-immunoreactive cells and fibers were extensively distributed in the forebrain and pituitary of Cirrhinus cirrhosus. NPY immunoreactivity was observed in the olfactory receptor neurons, ganglion cells of terminal nerve, and in neurons of area ventralis telencephali/pars lateralis, EN, nucleus preopticus periventricularis (NPP), and nucleus lateralis tuberis. NPY-fibers were observed in the dorsal telencephalon, tuberal area and pituitary. While the area ventralis telencephali/pars intermedialis (Vi) located just above the EN contained a distinct population of tyrosine hydroxylase neurons, their axons seem to innervate NPY neurons in EN. Superfused brain slices containing EN were treated with DA D1- and D2-like receptor agonists. NPY-immunoreactivity in the EN showed significant increase (P<0.001) following DA D1-like receptor agonist, SKF-38393 treatment, but DA D2-like receptor agonist, quinpirole was ineffective. DA may regulate NPY neurons in EN via D1-like receptors. DA-NPY interaction in the EN might be important in the central regulation of reproduction in teleosts.

Alpha-melanocyte stimulating hormone modulates ethanol self-administration in posterior ventral tegmental area through melanocortin-4 receptors.

Although the role of alpha-melanocyte stimulating hormone (α-MSH) in alcohol seeking behaviour in rats has been demonstrated, the underlying mechanisms are not understood. Herein, we test the hypothesis that α-MSH might have a permissive effect in promoting the reward action of ethanol. Rats were implanted with cannulae targeted at the posterior ventral tegmental area (pVTA), because the site is sensitive to reinforcing effects of ethanol. These rats were trained to self-administer ethanol in standard two-lever (active/inactive) operant chamber test. Each active lever press resulted in self-administration of 100 nl of ethanol (100-300 mg%) containing solution. Over a period of 7 days, ethanol significantly increased the number of lever presses, which was considered as a measure of reward. Because ethanol at 200 mg% resulted in maximum number of lever presses (∼18-20 lever presses/30-minute session), the dose was employed in further studies. While prior administration of melanocortin (MC) agonists, α-MSH or [Nle4,D-Phe7]-alpha-MSH into pVTA, resulted in an 89% increase in lever presses, the response was attenuated following pre-treatment with MC4 receptors (MC4R) antagonist, HS014. In an immunohistochemical study, the brains of rats that were trained to self-infuse ethanol showed significantly increased α-MSH immunoreactivity in the nucleus accumbens shell, bed nucleus of stria terminalis and arcuate nucleus of the hypothalamus. In the pVTA, α-MSH fibres were found to run close to the dopamine cells, labelled with tyrosine hydroxylase antibodies. We suggest that α-MSH-MC4R system in the pVTA might be a part of the neuroadaptive mechanism underlying ethanol addiction.

Prevalence of non-communicable chronic diseases in rural India amongst peri- and post-menopausal women: Can artificial intelligence help in early identification?

AIMS: To identify peri- and post-menopausal women at risk of non-communicable diseases in rural India and to assess their prevalence amongst these groups via the use of artificial intelligence. SETTINGS AND DESIGN: An observational study conducted by the Indian Menopause Society in collaboration with the Government of Maharashtra. The study included rural women residents of three villages in the Latur district of Maharashtra, India. MATERIALS AND METHODS: Accredited social health activist workers identified 400 peri- and post-menopausal women aged 45-60 years. Specific symptoms able to predict the presence of a non-communicable disease were identified through the use of artificial intelligence. STATISTICAL ANALYSIS USED: Descriptive statistics and predictive network charts analysis. RESULTS: The mean age of 316 women included in the analysis was 50.4 years and the majority of them were illiterate (68 %). The prevalence of dyslipidaemia, osteopenia, diabetes mellitus, obesity and hypertension were 58 %, 50 %, 25 %, 25 %, and 20 % respectively. None of their symptoms or laboratory reports could be significantly correlated directly with any of these non-communicable diseases. Hence, we used a cluster of symptoms to suggest the presence of hypertension, diabetes mellitus, osteoporosis and hypothyroidism via predictive network analysis charts. CONCLUSIONS: Screening of at-risk women can be done using an artificial intelligence-based screening tool for early diagnosis, timely referral and treatment of non-communicable diseases with the support of community health workers.

Prevalence of latent tuberculosis infection in Asian nations: A systematic review and meta-analysis.

BACKGROUND: Tuberculosis (TB) is a serious public health concern around the world including Asia. TB burden is high in Asian countries and significant population harbor latent tuberculosis infection(LTBI). AIM: This systematic review and meta-analysis aims to evaluate the prevalence of LTBI in Asian countries. METHOD: We performed a systematic literature search on PubMed, Embase, and ScienceDirect to identify relevant articles published between January 1, 2005, and January 1, 2023 investigating the overall prevalence of latent TB among people of Asia. Subgroup analysis was done for Asian subregions during the study period of 2011 to 2016 and 2017 to 2023, for tuberculin skin test (TST) and interferon gamma release assay (IGRA), respectively, as well as for QuantiFERON-TB (QFT) and TSPOT TB tests. Der Simonian and Laird's random-effects model was used to pool the prevalence of LTBI found using TST and IGRA. RESULT: A total of 15 studies were included after a systematic search from standard electronic databases. The analysis showed that the prevalence of latent TB in Asia was 21% (95% confidence interval [CI]: 19%-23%) and 36% (95% CI: 12%-59%) according to IGRAs and TSTs (cut off 10 mm) results, respectively. Based on IGRA, the prevalence of latent TB was 20% (95% CI: 13%-25%) in 2011 to 2016 and 21% (95% CI: 18%-24%) in 2017 to 2023. Using QFT, the prevalence was 19% (95% CI: 17%-22%) and using TSPOT, the prevalence was 26% (95% CI: 21%-31%). According to the United Nations division of Asia, the prevalence was higher for the Southern region and least for the Western region using TST and higher in the South-Eastern region and least in the Western region using the IGRA test. CONCLUSION: Almost a quarter of the Asian population has LTBI. Its diagnosis often poses a diagnostic challenge due to the unavailability of standard test in certain areas. Given this prevalence, a mass screening program is suggested with the available standard test and public awareness along with anti-TB regimen should be considered for individuals who test positive. However, for it to be implemented effectively, we need to take the affordability, availability, and cost-effectiveness of such interventions into account.

Plankton diversity and water quality assessment of three freshwater lakes of Mandi (Himachal Pradesh, India) with special reference to planktonic indicators.

The present study deals with the limnobiotic status of three selected lakes of Himachal Pradesh using physicochemical and biological parameters (especially phytoplankton and zooplankton) over a period of 2 years. One hundred forty-eight species belonging to nine groups of phytoplankton and 79 species belonging to five groups of zooplankton were identified from the lakes. Trophic level and the pollution status of the lakes were assessed upon the basis of Shannon diversity index (H'), species richness index (S), and physicochemical parameters. Plankton population size was correlated with biotic and abiotic parameters (pH, alkalinity, temperature, dissolved oxygen, transparency, phosphate, chloride, and nitrate). The present investigation revealed that the distribution of plankton species depended upon the physicochemical parameters of the environment. Based on water quality standards given by the Central Pollution Control Board, the water quality was between "A-B" at Prashar wetland, "C-D" at Kuntbhyog Lake, and "D-E" at Rewalsar Lake. The results from the present study indicated that the potential of planktons as bioindicators of trophic status is very high.

Job Satisfaction among Indian Migrants and Nonmigrants and its Relationship with their Psychological Profile-A Cross-Sectional Study.

Background: Unemployment, insufficient resources, family poverty, and poor financial benefits are crucial determinants for internal or external migration of large sections of educated youth. Aims: To perform a comparative analysis of different levels of job satisfaction and the status of mental morbidity among migrant and nonmigrant population. Settings and Design: A cross-sectional study was employed between March 2016 and October 2017 at the field practice area of one of the tertiary health care institutes in Anand District of Gujarat State of India. Methods and Material: A total of 456 educated and skilled professionals participated in the study. Job descriptive index, Job in General, and Global Health Questionnaire-28 were utilized. Statistical Analysis: The data entry was performed in Epi Info™ 7 followed by data analysis in EPI-INFO Software. Results and Conclusions: The overall job satisfaction in the study was found to be significantly higher among nonmigrants than migrants. All three scores were correlated with each other significantly. Overall, migrants were found to be significantly less satisfied with their jobs in general and more psychologically distressed, as compared to their nonmigrant counterparts.

Acute haemorrhagic necrotizing encephalopathy associated with COVID-19 in a patient with liver cirrhosis.

COVID-19 is emerging as a global pandemic and is a complex disease presenting with multi-organ involvement. Acute haemorrhagic necrotizing encephalopathy (AHNE) is a rarely reported phenomenon post-COVID-19 but is a rapidly progressing, fatal, haemorrhagic necrosis of the CNS parenchyma. Here, we present a very interesting case of a cirrhotic male patient with AHNE with COVID-19. Diagnosis of AHNE requires a multimodality approach and high index of suspicion in a patient suffering from SARS-CoV-2. Timely intervention and diagnosis may lead to a favourable outcome in the diagnosed cases. Future detailed studies in this direction may give an insight into this rare but important disease entity.
