Diagnostic utility of fine needle aspiration cytology in thyroid lesions

Background: Thyroid fine needle aspiration cytology (FNAC) is an important screening tool and thereby dictates clinical management. The exclusion of non-invasive follicular variant of papillary carcinoma (NIFVPTC) from thyroid malignancies and its reclassification as non-malignant entity i.e., non-invasive follicular thyroid neoplasm with papillary like nuclear features (NIFTP) has added a new dimension. Aim of this study was to study the role of fine needle aspiration cytology in screening thyroid lesions by correlation with histopathological examination and to calculate diagnostic accuracy of FNAC considering NIFTP as non-malignant and compare it with pre NIFTP era.Methods: It was an observational study done over a period of 2 years (2017-2018). It included the cases where FNAC was followed subsequently by histopathology. FNAC results were correlated with histopathological diagnosis established thereof.Results: A total of 107 patients were included in this study. Considering NIFTP as non-malignant, sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were 92.97%, 100%, 100%, 92.73% and 96.23% respectively, that is significantly higher if authors considered NIFTP as malignant.Conclusions: FNAC plays an indispensable role in making preliminary diagnosis in thyroid lesions. There is a notable increase in diagnostic accuracy of FNAC in thyroid lesions and significant decrease in risk of malignancy by considering NIFTP as non-malignant

Organic farming: Present status, scope and prospects in northern India

Organic agriculture has emerged as an important priority area globally in view of the growing consciousness for safe and healthy food, long term sustainability and environmental concerns despite being contentious in history. Green revolution although paved way for developing countries in self-sufficiency of food but sustaining production against the limited natural resource base demands has shifted steadily from “resource degrading” chemical agriculture to “resource protective” organic agriculture. The essential concept remains the same, i.e., to go back to the arms of nature and take up organic farming to restore the loss. Organic farming emphasizes on rotating crops, managing pests, diversifying crops and livestock and improving the soil. The rainfed areas particularly north-eastern regions where least or no utilization of chemical inputs due to poor resources provides considerable opportunity for promotion of organic farming thereby reflecting its vast but unexplored scope. However, significant barriers like yield reduction, soil fertility enhancement, integration of livestock, marketing and policy etc., arise at both macroscopic and microscopic levels; making practically impossible the complete adoption of ‘pure organic farming’; rather some specific area can be diverted to organic farming and thus a blend of organic and other innovative farming systems is needed. Adoption of Integrated Green Revolution Farming can be possible to a large extent, where the basic trends of green revolution are retained with greater efficiency and closer compatibility to the environment. This review paper attempts to present the recent global and regional scenario of organic farming particularly highlighting the scope, prospects and constraints in the northern areas

Uvođenje novog katetera u cistostomiji kliničkih slučajeva opstruktivne urolitijaze u goveda.

The present study was carried out to evaluate a simple innovative tube cystostomy technique for the management of bovine clinical cases of obstructive urolithiais. The materials of this study formed 20 clinical cases of obstructive urolithiasis, equally and randomly distributed in two groups. Diagnosis of the disease was made on the basis of a history of anuria, clinical signs, radiographic and ultrasonographic examinations. The confirmed cases of obstructive urolithiasis were managed by two surgical techniques, i.e., tube cystostomy with Foley’s catheter (group A) and tube cystostomy with simple polyvinyl chloride catheter tubing (group B). In all the animals litholytic agents, anti-infl ammatory drugs and antibiotics, along with urine acidifiers, were given. The surgical techniques were evaluated on the basis of clinical, haematobiochemical parameters, and postoperative surgical complications. Duration of surgery and overall success rate were also recorded in each group. Haematobiochemical alterations returned to normalcy more quickly in the animals of group A as compared to those of group B. The survival rate was similar in the animals of both the groups; however complications like catheter blockade were found more often in group A animals. Tube cystostomy with polyvinyl chloride tubing may be a feasible method for the management of obstructive urolithiasis in field conditions. It needs more refinement and further evaluation before its recommendation for in field use.Ovo istraživanje bilo je provedeno radi prosudbe vrijednosti novoga jednostavnoga postupka cistostomije pri obradi kliničkih slučajeva opstruktivne urolitijaze u goveda. Dvadeset goveda s klinički dokazanom opstruktivnom urolitijazom bilo je nasumce podijeljeno u dvije skupine po deset goveda. Dijagnoza je bila postavljena na osnovi podataka o anuriji, prisutnim kliničkim znakovima te na osnovi radiografske i ultrazvučne pretrage. Potvrđeni slučajevi opstruktivne urolitijaze bili su obrađeni dvama kirurškim postupcima: cistostomijom kod koje je bio rabljen Foleyev kateter (skupina A) i uporabom jednostavnoga polivinil-kloridnoga katetera (skupina B). Svima životinjama bile su primijenjene litolitičke tvari, protuupalni lijekovi, antibiotici i sredstva za zakiseljavanje mokraće. Kirurške tehnike bile su vrednovane na osnovi kliničkih, hematoloških i biokemijskih pokazatelja i postoperativnih kirurških komplikacija. Za svaku skupinu uzeto je u obzir trajanje operacije i njezina uspješnost. Promjene u hematološkim i biokemijskim pokazateljima brže su se vratile na normalne vrijednosti u životinja skupine A u odnosu na skupinu B. Stopa preživljavanja bila je slična u životinja obiju skupina. Međutim, komplikacije poput začepljenja katetera bile su češće u životinja skupine A. Cistostomija pri kojoj je rabljen polivinil-kloridni kateter lako je izvediva metoda za obradu opstruktivne urolitijaze u terenskim uvjetima. Ipak, prije preporuke za terensku uporabu nužno je njezino daljnje usavršavanje

Correlation of prothrombin time and activated partial thromboplastin time with serum immunoglobulin and M-band in newly diagnosed multiple myeloma patients

Background: Multiple myeloma is the second most frequent malignancy which constitute 13% of hematologic cancers. Thrombotic and hemorrhagic complications have been frequently observed in multiple myeloma patients. Methods: The study was conducted in the department of pathology, Government medical college Srinagar. A total of fifty (50) patients were recruited for the study. The patients were advised coagulation profile and complete myeloma profile. Results: Our findings indicate that prolonged PT is associated with high serum IgG levels. A mild to moderate correlation was seen with kappa-free light chains and an inverse correlation was seen between PT and lmbda-free light chains. Conclusions: Screening of multiple myeloma for hemostatic abnormalities at the diagnosis should improve prognosis in such cases

Effects of a Home-Based Exercise Program on Inflammatory Cytokines and Functional Capacity in Men with Prostate Cancer Under Active Surveillance

Regular exercise can improve physical fitness, functional performance, and quality of life in men with prostate cancer (PCa); however, few men with PCa meet national physical activity guidelines. Structured, home-based exercise programs may bridge this gap and increase physical activity in men with PCa. PURPOSE: This pilot study aimed to investigate the impact of a home-based exercise program on cytokines associated with tumor progression in men with PCa. METHODS: A single group, self-controlled study design was used. Fifteen men with PCa under active surveillance were recruited to complete 24 weeks of a home-based exercise program, combining aerobic and body-weight based exercises. The aerobic portion of the intervention included 5 days of light-to-moderate intensity walking for 30 minutes at 40-60% of the participant’s heart rate reserve as calculated using the Karvonen formula. Body-weight based exercises were performed 3 times per week consisting of 3 sets of 15 reps of bodyweight squats, inclined push-ups, and hip thrusts. Serum was collected at baseline and end of study to measure circulating eotaxin, interferon (IFN)γ, interleukin (IL)-12, IL-1a, IL-5, IL-6, tumor necrosis factor (TNF)-α, and vascular endothelial growth factor (VEGF) cytokines using an 8-protein multiplex (Millipore Sigma, Billerica, MA). A 6-minute walk test (MWT)was completed at the beginning and end of study to measure physical function. T-tests were performed with significance set to p \u3c0.05. RESULTS: A total of 15 men were consented with 9 men completing the intervention (40% attrition due to COVID). At baseline, participants were 70.11 ± 5.42 years of age, weighted 85.31 ± 6.41 kg with a body mass index of 27.77 ± 2.93 kg/m2. A non-significant tendency was observed for improved 6MWT distance (meters) (Pre: 382.7 ± 108.1; Post: 466.7 ± 73.78; p=0.08). Analysis of circulating cytokines showed tendencies for reduced circulating concentrations (pg/mL) of IFNγ (Pre: 152.9 ± 312.7; Post: 118.9 ± 258.8; p=0.08), and VEGF (Pre: 125.2 ± 198.7; Post: 80.29 ± 124.3; p=0.06) following the intervention. Several other biomarkers showed relevant, though not significant, decreases as well, including IL-12 (Pre: 28.69 ± 32.06; Post: 23.92 ± 19.38; -16.6%), IL-1a (Pre: 78.76 ± 183.3; Post: 65.55 ± 147.7; -16.8%), IL-6 (Pre: 23.71 ± 45.64; Post: 21.24 ± 45.18; -10.4%), and TNF-α (Pre: 24.58 ± 35.4; Post: 19.71 ± 20.76; -19.8%). CONCLUSION: Due to institutional COVID-19 protocols limiting in person research visits, six participants declined to continue the study. The small sample size likely accounts for the lack of statistically significant findings. Although the study did not yield statistically significant outcomes, the results of this study show promising indications that a home-based exercise program could be effective in reducing inflammatory cytokines and increasing functional capacity in men with PCa. Further investigation is needed to confirm these results with a powered sample

Impact of a Home-Based Exercise Program on Cardiovascular Disease Biomarkers in Men with Prostate Cancer

Patients with prostate cancer (PCa) tend to live a sedentary lifestyle and fail to meet national physical activity requirements putting them at a greater risk for developing weight-related co-morbidities and cancer recurrence. Physical activity after cancer diagnosis is known to improve body composition, physical function, and overall quality of life. The inclusion of a home-based exercise regimen may increase their physical activity and reduce the risk of weight-related illness. PURPOSE: To gather preliminary data regarding the impact of a home-based exercise program on body composition and cardiovascular disease (CVD) biomarkers. METHODS: A single group self-controlled study design was used to test the hypothesis that a home-based exercise program can reduce CVD risk in men with PCa. Fifteen men with PCa under active surveillance were recruited to complete a 24-week home-based exercise program consisting of both aerobic and strength-based exercises. Each week, participants were asked to complete 5 days of light-to-moderate intensity walking at a heart rate reserve of 40-60% and 3 days of bodyweight-based exercises including 3 sets of 15 reps of squats, incline push-ups, and hip thrusts. Serum was collected at baseline and end of study to quantify circulating CVD biomarkers: a-2 macroglobulin (A2M), C-reactive protein (CRP), fetuin-A, a-1 acid glycoprotein (AGP), fibrinogen, L-selectin, serum amyloid P (SAP), platelet factor 4 (PF4/CXCL4), and adipsin using an 8-protein multiplex (Millipore Sigma, Billerica, MA). T-tests were performed with significance established at pRESULTS: A total of 15 men consented and 9 men saw the trial to completion (Age: 72.0 ± 8.52; Weight: 85.31 ± 6.41 kg; BMI: 27.77 ± 2.93 kg/m2). There was a 40% rate of attrition observed due to COVID-19. No significant changes occurred in average weights and BMI from pre to post trial visits. Though not significant, tendencies for increased concentrations of the anticoagulant, A2M (Pre: 99.83 ± 81.19 pg/mL; Post: 126.7 ± 102.5; p=0.064) and the inflammatory protein, SAP (Pre: 0.63 ± 0.32 pg/mL; Post: 0.86 ± 0.46; p=0.09) were seen. We also observed a 1.5-fold increase in CRP (Pre: 0.47 ± 0.38 pg/mL; Post: 1.19 ± 2.209) perhaps, as a result of an increase in SAP, or indicative of increased levels of stress due to COVID-19. No other significant differences were found. CONCLUSION: The reduced sample size may have contributed to the lack of significance found in the analysis. Although there were no statistically significant findings, the tendencies seen in A2M suggest that a home-based exercise program may protect against certain facets of CVD in this overweight population. However, our enthusiasm is blunted by the observed increases in SAP and CRP. Further investigation is necessary to validate these results

Transition metal doped CeO2 for photocatalytic removal of 2-chlorophenol in the exposure of indoor white light and antifungal activity

Besides natural sunlight and expensive artificial lights, economical indoor white light can play a significant role in activating a catalyst for photocatalytic removal of organic toxins from contaminated water. In the current effort, CeO2 has been modified with Ni, Cu, and Fe through doping methodology to study the removal of 2-chlorophenol (2-CP) in the illumination of 70 W indoor LED white light. The absence of additional diffractions due to the dopants and few changes such as reduction in peaks’ height, minor peak shift at 2θ (28.525°) and peaks’ broadening in XRD patterns of modified CeO2 verifies the successful doping of CeO2. The solid-state absorption spectra revealed higher absorbance of Cu-doped CeO2 whereas a lower absorption response was observed for Ni-doped CeO2. An interesting observation regarding the lowering of indirect bandgap energy of Fe-doped CeO2 (∼2.7 eV) and an increase in Ni-doped CeO2 (∼3.0 eV) in comparison to pristine CeO2 (∼2.9 eV) was noticed. The process of e-– h+ recombination in the synthesized photocatalysts was also investigated through photoluminescence spectroscopy. The photocatalytic studies revealed the greater photocatalytic activity of Fe-doped CeO2 with a higher rate (∼3.9 × 10−3 min-1) among all other materials. Moreover, kinetic studies also revealed the validation of the Langmuir-Hinshelwood kinetic model (R2 = 0.9839) while removing 2-CP in the exposure of indoor light with a Fe-doped CeO2 photocatalyst. The XPS analysis revealed the existence of Fe3+, Cu2+ and Ni2+ core levels in doped CeO2. Using the agar well-diffusion method, the antifungal activity was assessed against the fungus M. fructicola and F. oxysporum. Compared to CeO2, Ni-doped CeO2, and Cu-doped CeO2 nanoparticles, the Fe-doped CeO2 nanoparticles have outstanding antifungal properties

Obeticholic acid for the treatment of non-alcoholic steatohepatitis: interim analysis from a multicentre, randomised, placebo-controlled phase 3 trial

Background Non-alcoholic steatohepatitis (NASH) is a common type of chronic liver disease that can lead to cirrhosis. Obeticholic acid, a farnesoid X receptor agonist, has been shown to improve the histological features of NASH. Here we report results from a planned interim analysis of an ongoing, phase 3 study of obeticholic acid for NASH. Methods In this multicentre, randomised, double-blind, placebo-controlled study, adult patients with definite NASH,non-alcoholic fatty liver disease (NAFLD) activity score of at least 4, and fibrosis stages F2–F3, or F1 with at least oneaccompanying comorbidity, were randomly assigned using an interactive web response system in a 1:1:1 ratio to receive oral placebo, obeticholic acid 10 mg, or obeticholic acid 25 mg daily. Patients were excluded if cirrhosis, other chronic liver disease, elevated alcohol consumption, or confounding conditions were present. The primary endpointsfor the month-18 interim analysis were fibrosis improvement (≥1 stage) with no worsening of NASH, or NASH resolution with no worsening of fibrosis, with the study considered successful if either primary endpoint was met. Primary analyses were done by intention to treat, in patients with fibrosis stage F2–F3 who received at least one dose of treatment and reached, or would have reached, the month 18 visit by the prespecified interim analysis cutoff date. The study also evaluated other histological and biochemical markers of NASH and fibrosis, and safety. This study is ongoing, and registered with ClinicalTrials.gov, NCT02548351, and EudraCT, 20150-025601-6. Findings Between Dec 9, 2015, and Oct 26, 2018, 1968 patients with stage F1–F3 fibrosis were enrolled and received at least one dose of study treatment; 931 patients with stage F2–F3 fibrosis were included in the primary analysis (311 in the placebo group, 312 in the obeticholic acid 10 mg group, and 308 in the obeticholic acid 25 mg group). The fibrosis improvement endpoint was achieved by 37 (12%) patients in the placebo group, 55 (18%) in the obeticholic acid 10 mg group (p=0·045), and 71 (23%) in the obeticholic acid 25 mg group (p=0·0002). The NASH resolution endpoint was not met (25 [8%] patients in the placebo group, 35 [11%] in the obeticholic acid 10 mg group [p=0·18], and 36 [12%] in the obeticholic acid 25 mg group [p=0·13]). In the safety population (1968 patients with fibrosis stages F1–F3), the most common adverse event was pruritus (123 [19%] in the placebo group, 183 [28%] in the obeticholic acid 10 mg group, and 336 [51%] in the obeticholic acid 25 mg group); incidence was generally mild to moderate in severity. The overall safety profile was similar to that in previous studies, and incidence of serious adverse events was similar across treatment groups (75 [11%] patients in the placebo group, 72 [11%] in the obeticholic acid 10 mg group, and 93 [14%] in the obeticholic acid 25 mg group). Interpretation Obeticholic acid 25 mg significantly improved fibrosis and key components of NASH disease activity among patients with NASH. The results from this planned interim analysis show clinically significant histological improvement that is reasonably likely to predict clinical benefit. This study is ongoing to assess clinical outcomes

Measuring progress and projecting attainment on the basis of past trends of the health-related Sustainable Development Goals in 188 countries: an analysis from the Global Burden of Disease Study 2016

The UN’s Sustainable Development Goals (SDGs) are grounded in the global ambition of “leaving no one behind”. Understanding today’s gains and gaps for the health-related SDGs is essential for decision makers as they aim to improve the health of populations. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016), we measured 37 of the 50 health-related SDG indicators over the period 1990–2016 for 188 countries, and then on the basis of these past trends, we projected indicators to 2030
