Heat ameliorative measures in Murrah buffalo (Bubalus bubalis) heifers during summer: effect on microclimate, thermal comfort, and behavior.

Water buffalo (Bubalus bubalis) is the mainstay of milk production in Asian countries including India. However, the hot climate of the country remains the biggest bottleneck to exploit the potential of this species. Therefore, a study was conducted to assess the effect of heat ameliorative measures on microclimate, thermal comfort, and behavior of Murrah buffalo heifers during summer. Buffalo heifers (n = 24) between the age of 15 and 20 months with a mean body weight of 363.75 ± 11.27 kg were randomly grouped into four treatments based on their age and body weight. The heifers kept in the shed without any cooling served as CON (control), while the animals of group CJ were tied with a cooling jacket. The buffalo heifers of the CJF group were subjected to the cooling jacket with forced air ventilation, whereas the intermittent (10 min at 2-h intervals) sprinkling followed by forced air ventilation was practiced in group SF between 900 and 1800 h throughout the experiment. The microclimatic variables were low in the sheds of groups CJ, CJF, and SF than the CON. The physiological responses such as rectal temperature, skin temperature, respiration rate, and pulse rate were reduced in groups CJ, CJF, and SF than the CON at 1400 h. The serum cortisol was less in the CJF and SF than those of CON group. The animals of the CJ, CJF, and SF groups spent more time for feeding and rumination with less frequent longer bouts. The extended periods of lying followed by shorter standing and idling were observed in groups CJ, CJF, and SF when compared with the CON. It may be therefore concluded that cooling jacket and intermittent sprinkling in combination with forced air ventilation might be helpful in improving the micro-environment, thermal comfort, and behavior of buffalo heifers particularly under tropical climates during summer.

Rational synthesis, anticancer activity, and molecular docking studies of novel benzofuran liked thiazole hybrids.

A novel series of benzofuran bearing thiazole hybrids were synthesized by the multistep reaction approach. All synthesized molecules were selected by the National Cancer Institute, USA for one-dose anticancer activity against 60 various human cancer cell lines indicating nine types of cancer. Among thirteen compounds, two compounds showed higher lethality, so, it was selected for five-dose anticancer screening against all cancer cell lines. Compound 8g and 8h were displayed remarkable antiproliferative activity with GI50 values ranging from 0.295 to 4.15 µM and LC50 values ranging from 4.43 to > 100 µM. All data are compared with standard drugs fluorouracil and doxorubicin. Compound 8g showed higher potency as a cytotoxic molecule then fluorouracil. Furthermore, all new hybrids were studied for molecular docking into the active binding sites of 1HOV protein.

The role of primary school composition in affective decision-making: a prospective cohort study.

PURPOSE: School-level characteristics are known to be associated with pupils' academic and cognitive ability but also their socioemotional development. This study examines, for the first time, whether primary school characteristics are associated with pupils' affective decision-making too. METHODS: The sample included 3,141 children participating in the Millennium Cohort Study with available data on their school's characteristics, according to the National Pupil Database, at age 7 years. Decision-making was measured using the Cambridge Gambling Task at age 11 years. We modelled data using a series of sex-stratified linear regression analyses of decision-making (risk-taking, quality of decision-making, risk adjustment, deliberation time, and delay aversion) against four indicators of school composition (academic performance and proportions among pupils who are native speakers of English, are eligible for free school meals and have special educational needs). RESULTS: After adjustment for individual and family-level confounding, schools with a higher average academic performance showed more delay aversion among males, and among females, higher deliberation time and lower risk-taking. Schools with proportionally more native English speakers had higher deliberation time among males. Schools with proportionally more pupils eligible for free school meals showed lower scores on quality of decision-making among males. Schools with proportionally more children with special educational needs showed better quality of decision-making among males and lower risk-taking among females. CONCLUSION: The findings of this study can be used to target support for primary schools. Interventions aiming to support lower-achieving schools and those with less affluent intakes could help to improve boys' affective decision-making.

A keyhole approach gives a sound repair for ileal conduit parastomal hernia.

PURPOSE: The purpose of this study was to report and evaluate a laparoscopic surgical technique for the treatment of parastomal hernia (PSH) after ileal conduit urinary diversion aiming to minimize PSH recurrence and perioperative complications. METHODS: We retrospectively evaluated all patients who underwent a PSH (after ileal conduit urinary diversion) repair at Addenbrookes Hospital, Cambridge. As a surgical approach, a laparoscopic repair with mesh was utilized in all cases. Subsequently, we performed a voluntary follow-up of the patients to evaluate long-term recurrence and complication rates. In addition, we conducted a reassessment of the cross-sectional imaging available. RESULTS: Between November 2008 and December 2019, 27 patients underwent hernia repair due to a clinically significant hernia. Out of those patients, one suffered from a post-operative wound infection. In total 23 patients participated in the follow-up with a median follow-up period of 91 months. Follow-up examination revealed two cases of recurrent PSH (8.7% of patients followed up), four patients suffered from minor complications (14.8%). CONCLUSION: Repair of PSH associated with ileal conduit is particularly scarce. Our surgical approach presents the only laparoscopic case series of an effective method for treating a PSH from an ileal conduit with a low complication and recurrence rate.

Reversal of left-sided colostomy utilizing single-port laparoscopy a multicenter European audit and overview of the literature.

BACKGROUND: Stoma reversal surgery can result in considerable morbidity and even mortality. Feasibility of utilizing single-port laparoscopy through the stoma fenestration have been shown before. Aim of the present observational study is to evaluate multicenter experiences of single-port reversal of left-sided colostomy (SPRLC) throughout Europe and to provide an overview of available literature on this topic. METHODS: All patients undergoing SPRLC in four different teaching hospitals throughout Europe are included. Primary outcome was 30-day postoperative complication rate. Secondary outcomes were postoperative length of stay (LOS), single-port success rate and conversion rates. Appraisal of the available literature in PubMed was performed. RESULTS: Of 156 SPRLC procedures, 98.7% of them were technically successful and 71.8% were without postoperative complications. No postoperative mortality was encountered. Superficial site infection occurred in 14.7%, anastomotic leakage in 3.9% and major complications in 8.3%. Median LOS was 4.0 days (1-69), single-port success rate was 64.7%, 12.8% and 21.2% (33/154) were converted to an open and multiport laparoscopic procedure, respectively. Literature shows equally favorable results in 131 patients divided over 5 cohorts with morbidity ranging from 0 to 30.4% and mortality from 0 to 2.2% and median LOS of 4-8 days. CONCLUSION: This study confirms the safety, feasibility and favorable results of the use of single-port approach in the reversal of left-sided colostomy in different centers in Europe with laparoscopic experienced colorectal surgeons. The available literature on this topic support and show equally favorable results using single-port laparoscopy for left-sided colostomy reversal surgery.

Modulation of optical absorption in m-Fe1-xRuxS2 and exploring stability in new m-RuS2.

A first-principle computational method has been used to investigate the effects of Ru dopants on the electronic and optical absorption properties of marcasite FeS2. In addition, we have also revealed a new marcasite phase in RuS2, unlike most studied pyrite structures. The new phase has fulfilled all the necessary criteria of structural stability and its practical existence. The transition pressure of 8 GPa drives the structural change from pyrite to orthorhombic phase in RuS2. From the thermodynamical calculation, we have reported the stability of new-phase under various ranges of applied pressure and temperature. Further, from the results of phonon dispersion calculated at Zero Point Energy, pyrite structure exhibits ground state stability and the marcasite phase has all modes of frequencies positive. The newly proposed phase is a semiconductor with a band gap comparable to its pyrite counterpart but vary in optical absorption by around 106 cm-1. The various Ru doped structures have also shown similar optical absorption spectra in the same order of magnitude. We have used crystal field theory to explain high optical absorption which is due to the involvement of different electronic states in formation of electronic and optical band gaps. LÓ§wdin charge analysis is used over the customarily Mulliken charges to predict 89% of covalence in the compound. Our results indicate the importance of new phase to enhance the efficiency of photovoltaic materials for practical applications.

Transperineal minimally invasive APE: preliminary outcomes in a multicenter cohort.

BACKGROUND: Abdominoperineal excision (APE) for rectal cancer is associated with a relatively high risk of positive margins and postoperative morbidity, particularly related to perineal wound healing problems. It is unknown whether the use of a minimally invasive approach for the perineal part of these procedures can improve postoperative outcomes without oncological compromise. The aim of this study was to evaluate the feasibility of minimally invasive transperineal abdominoperineal excision (TpAPE) METHODS: This multicenter retrospective cohort study included all patients having TpAPE for primary low rectal cancer. The primary endpoint was the intraoperative complication rate. Secondary endpoints included major morbidity (Clavien-Dindo ≥ 3), histopathology results, and perineal wound healing. RESULTS: A total of 32 TpAPE procedures were performed in five centers. A bilateral extralevator APE (ELAPE) was performed in 17 patients (53%), a unilateral ELAPE in 7 (22%), and an APE in 8 (25%). Intraoperative complications occurred in five cases (16%) and severe postoperative morbidity in three cases (9%). There were no perioperative deaths. A positive margin (R1) was observed in four patients (13%) and specimen perforation occurred in two (6%). The unilateral extralevator TpAPE group had worse specimen quality and a higher proportion of R1 resections than the bilateral ELAPE or standard APE groups. The rate of uncomplicated perineal wound healing was 53% (n = 17) and three patients (9%) required surgical reintervention. CONCLUSIONS: TpAPE seems to be feasible with acceptable perioperative morbidity and a relatively low rate of perineal wound dehiscence, while histopathological outcomes remain suboptimal. Additional evaluation of the viability of this technique is needed in the form of a prospective trial with standardization of the procedure, indication, audit of outcomes and performed by surgeons with vast experience in transanal total mesorectal excision.

[Validation of the Russian version of the ureteral stent symptoms questionnaire (USSQ) for the evaluation of quality of life and stent-related symptoms].

INTRODUCTION: Ureteral stents are frequently used in urology practice and have a significant impact on health-related quality of life (QoL). In 2003 . Joshi et al. developed the specific questionnaire for evaluation of QoL and stent-related symptoms, namely Ureteral Stent Symptoms Questionnaire (USSQ). USSQ consists of 40 questions and 2 visual analog scales (VAS), divided into 6 domains. Over the past decade, this questionnaire has been translated into 9 languages. A Russian version of the questionnaire has not been developed yet. AIM: To perform linguistic validation of the Russian version of the USSQ. MATERIAL AND METHODS: Linguistic validation of the original USSQ was performed through a standard process including translation, back translation and pilot study. A total of 103 patients undergone ureteral stent placement and successfully filled in the Russian USSQ at weeks 1 and 4 after stenting, and at week 4 after stent removal. In addition, 30 healthy people filled in the same questionnaires twice at 3-week intervals, as a control group. To evaluate reliability, validity and sensitivity to change of the Russian USSQ, statistical analysis was performed. External criteria included validated questionnaires (EQ-5D, IPSS and pain VAS). RESULTS: Content validity was approved by experts and proved during patients interviewing. Reliability test-retest was satisfactory for urinary symptoms, body pain, general health, and work performance domains (p<0,001 between test and retest evaluation). USSQ domains showed good correlations between each other (correlation coefficient was 0,80-0,94). Cronbach's alpha coefficient of internal reliability was 0.73-0.95. Correlation between other instruments and corresponding USSQ domains was good (p<0,001), proving criterial validity. Sensitivity to changes after stenting and stent removal was also good for most domains (p less or equal 0,001). CONCLUSION: Russian version of USSQ is a valid, reliable and sensitive instrument for the assessment of QoL and stent-related symptoms and is ready for application in the routine clinical practice.

Clinical Profile of Patients Presenting with Gallstone Disease in University Hospital of Nepal.

Background Gallstone disease is one of the most common surgical problem throughout the world. The rise in gallstone disease burden and its wide spectrum of non-specific presentation makes the disease more challenging. Objective To know the various modes of presentation, socio-demographic details of the patients with gallstone disease, any associated factors and its treatment options. Method This is a prospective descriptive study in the patients presenting to Dhulikhel Hospital Kathmandu University Hospital diagnosed with gallstone during May 2018 to April 2020. After receiving ethical clearance from institutional Review committee, the informed consent was taken from all patient involved in the study. The presence of gallstone was confirmed by abdominal ultrasonography (USG). This study included total of 202 patients with gallstone disease. Result A total of 202 individuals with gallstone were included in the study; 48 males (24%) and 154 females (76%). The disease condition was common in age group 31-40 years (26.24%). Majority of the study population consumed mixed diet (92.57%). Out of 202 patients; 52 patients (25.74%) were overweight. In this study series 185 patients (91.58%) were symptomatic. Pain abdomen was one of the commonest symptoms (97.84%) followed by Nausea (28.11%), Dyspepsia (28.11%), Vomiting (18.38%), Fever (1.62) and Jaundice (1.08%). All cases were planned for laparoscopic cholecystectomy however 4 cases had to be converted to open surgery for completion. Conclusion Gallstone disease is a common surgical problem in Female population that presents most commonly with pain abdomen. Laparoscopic cholecystectomy can be easily performed in all cases of gallstone disease.

Types of Renal Stones and its Variation with Age and Gender in a University Hospital of Nepal.

Background Types of renal stones have profoundly changed in the last half-century, parallel to the change in lifestyle and dietary habit, with an increase of calcium stones. Among many lithogenic factors age and gender are considered to be associated with the types of renal stones. Studies evaluating the influence of age and gender on the distribution of the types of urinary calculi are scarce in Nepal. Objective To explore the influence of age and gender on different types of urolithiasis. Method This is a single center prospective study encompassing urolithiasis during a study period of 18 months. All the stone retrieved from the patients after surgery were sent for biochemical analysis of the stone. The result was then compared with the age and gender of the study population. Result Calculi from a total of 107 patients wereanalyzed (62 from malesand 45 from females). Mixed stones consisting of calcium oxalate and calcium phosphate werethe predominant constituent in 74.16% of stones, followed by uric acid, struvite and cystine stones. We found predominance of Calcium stones in males(47.66%) vs 36.44% in females and predominance of struvite stonesin females (7.47%) vs 3.73% in males. Age group of 21-40 years has the main burden of stone. Conclusion Being aware and having better knowledge of risk factors, composition and correlation with age and gender can provide personalized guidance to prevention and avoid recurrence of urolithiasis.

Outcome of Uretero Renoscopic Lithotripsy (URSL) with Holmium LASER Vs Pneumatic Lithotripter for Lower Ureteric Stones, Experience from University Hospital of Nepal.

Background There are various methods of endoluminal ureteral stone fragmentation. Among various modalities Laser lithotripsy and Pneumatic lithotripsy are commonly used and have shown comparable outcomes. Objective To compare the efficacy and outcome of laser and pneumatic lithotripsy in a patient with lower ureteric calculi. The comparison will be done in stone free rate, migration of stone and complication of the procedure. Method This is a prospective comparative study in a cohort of patients at University Hospital with Lower Ureteric stone. Ninety patients were randomized in to two groups (Laser Lithotripsy Vs Pneumatic Lithotripsy) during the study period. The purpose of this study was to measure the immediate stone free rate, intra-operative complications, mean operative time, post-operative complication and if any stone retention after six weeks follow up. Result Both the groups were similar in Age and Gender. Immediate stone free rate was slightly higher in Laser lithotripsy group (97.77%) in comparison to Pneumatic lithotripter group (84.44%) with p=0.507 which is not statistically significant. There was statistical difference in terms of stone migration rate, mean operation time in favor of Laser Lithotripsy group (p<0.01, in both parameters). There were no immediate complications in both the group however there were three cases of short segment ureteric strictures (6.66%) in case of Pneumatic lithotripsy on six weeks follow up which was managed conservatively. Conclusion Both LASER lithotripter and Pneumatic lithotripter are equally efficacious modality of endoluminal URSL in lower ureteric stone with similar Stone Free Rate. Laser lithotripsy showed lower frequency of stone migration and had shorter procedure time.

Study on Acute Renal Colic and Comparison of Diclofenac and Ketorolac in Pain Management in University Hospital, Kavre, Nepal.

Background Acute renal colic is the most frequent clinical presentations of renal stone and a common cause of patient visits to emergency departments worldwide. The prevalence of the renal stone disease has increased steadily over the past decades. Objective To describe the prevalence, epidemiological features and clinical management of renal colic patients at emergency department in Kathmandu University Hospital, Kavre, Nepal. Method Two hundred and thirty-six patients with acute renal colic presented in emergency department during a six-months period were included in the study. Using a standard predesigned proforma, demographic characteristics, presenting symptoms, practice of pain management and outcome were investigated. Renal colic attacks in patients were defined according to International Classification of Diseases, Tenth Revision, and Clinical Modification-10. Result Prevalence of renal colic was 2.61%. Mean age of the patients was 33.9±13.7 years. More than half of participants were male (54%). Majority of the patients (47.9%) were from Kavrepalanchowk district. The most common presenting symptom of the patients was flank pain on affected side (79.2%). In almost 43% of patients, diclofenac sodium was administered as a first line analgesic. There was no significant difference between diclofenac and ketolorac with respect to the need of second line analgesic (Chi-square value: 0.19, p value = 0.664). Conclusion Prevalence of renal colic was 2.61% at Dhulikhel hospital. More male pateints were affected and the most common presenting symptom was flank pain on the affected. Diclofenac and ketorolac are equally effective for the pain management of renal colic patients.

Increased multimodality treatment options has improved survival for Hepatocellular carcinoma but poor survival for biliary tract cancers remains unchanged.

BACKGROUND: Primary hepatobiliary cancer incidence in the UK is rising and survival rates are low. Surgery is the main curative option for these cancers, but multimodality therapies are expanding. The aim of our original study was to determine trends in survival, over an 8-year period, of patients treated for primary hepatobiliary cancers at our tertiary referral Centre. METHOD: Patients treated for the most common types of primary hepatobiliary cancers, namely Hepatocellular carcinoma (HCC), Cholangiocarcinoma and Gallbladder cancer between January 2009 and December 2016 were retrospectively analysed from a prospective database linked to UK Hospital Episode Statistics data. RESULTS: A total of 1536 patients with primary hepatobiliary cancers were assessed and treatment plans formulated at our supra-regional specialist Hepatobiliary MDT. The primary hepatobiliary cancers treated were HCC (n = 836), Cholangiocarcinoma (n = 516), and Gallbladder cancer (n = 184). Survival for all the 3 cancers was significantly better with curative treatment. Overall median survival times were 350, 180, and 150 days respectively for HCC, Cholangiocarcinoma and Gallbladder cancer. Excluding best supportive care patients, the respective survival figures were 900, 600, and 400 days. Survival for HCC patients improved over time and was significantly increased in the final 3 years of the study (p ≤ 0.011 for all). Cholangiocarcinoma and Gallbladder cancer survivals were poor and did not change significantly over time. CONCLUSION: HCC outcome has improved in association with expanded multimodal therapies. Survivals for cholangiocarcinoma and gallbladder cancer remain poor in parallel with limited expansion of multimodal therapies highlighting an unmet therapeutic need for biliary tract cancers.

Anterior hypopituitarism secondary to biopsy-proven IgG4-related hypophysitis in a young man.

IgG4-related disease (IgG4-RD) is an immune-mediated fibro-inflammatory condition which can affect various organs including the pituitary gland. The true annual incidence of this condition remains widely unknown. In addition, it is unclear whether IgG4 antibodies are causative or the end result of a trigger. With no specific biomarkers available, the diagnosis of IgG4-related hypophysitis remains a challenge. Additionally, there is a wide differential diagnosis. We report a case of biopsy-proven IgG4-related hypophysitis in a young man with type 2 diabetes mellitus. Learning points: IgG4-related hypophysitis is part of a spectrum of IgG4-related diseases. Clinical manifestations result from anterior pituitary hormone deficiencies with or without diabetes insipidus, which can be temporary or permanent. A combination of clinical, radiological, serological and histological evidence with careful interpretation is required to make the diagnosis. Tissue biopsy remains the gold standard investigation. Disease monitoring and long-term management of this condition is a challenge as relapses occur frequently.

Linguistic and cultural validation of Ureteral Stent Symptom Questionnaire in Hindi.

INTRODUCTION: In the year 2003, Joshi et al. developed a validated outcome assessment tool to measure the ureteral stent-related symptoms. The original English language Ureteral Stent Symptom Questionnaire (USSQ) has been validated in various languages worldwide. Our objective was to develop the USSQ in Hindi, a commonlyused language in India, by validating it in patients undergoing ureteroscopic lithotripsy. MATERIALS AND METHODS: A final Hindi version of the USSQ was derived from the original English version to apply to the study population by translation, back translation, and face-to-face interviews. The Hindi and English versions were completed by 70 patients undergoing ureteroscopic lithotripsy with stent in situ, on postoperative days 7 and 8, and 4 weeks after stent removal. Similarly, discriminant validity was checked among 50 healthy individuals. A detailed statistical analysis was used to correlate results (Cronbach's α coefficient, Spearman's correlation, and Mann-Whitney U-test). RESULTS: A total of 70 patients were enrolled in the study and 61 completed the final assessment. The median age was 35 years (range: 18-60 years). The USSQ domain scores with the stent in situ were higher than poststent status. The test-retest reliability checked by Cronbach's α coefficient (>0.44) and Spearman's correlation coefficient (>0.44) were acceptable to good. We found high discriminant validity of the questionnaire between patients with stent and the healthy controls (P < 0.05). CONCLUSION: Our results demonstrate satisfactory validity for the Hindi version of the USSQ for the assessment of quality of life in patients with stent. This is ready for application in the clinical studies and the future stent-related research in Hindi language.
