ABSTRACT
Right hepatic artery (RHA) is a branch of the common hepatic artery; however, there are cases documented in the literature showing anatomical variations. Accessory RHA is an incidental finding during hepatobiliary and pancreatic surgery. This artery should be identified, carefully separated, and preserved during these surgeries. We encounter the variation while doing Whipple’s procedure in a 61-year-old patient diagnosed with carcinoma of the head of the pancreas. Intra-operatively, accessory RHA was present which was arising from the superior mesenteric artery. It was identified, carefully separated, and preserved. Variations in the origin of the artery may make it vulnerable to injuries during surgical procedures if due care is not taken
ABSTRACT
Context: Complex left atrial appendage (LAA) morphology is increasingly associated with cryptogenic ischemic stroke as compared to cardioembolic stroke due to atrial fibrillation (AF). However, data on such an association in patients with other etiological stroke subtypes in the absence of AF is limited. Aim: The study aimed to assess the LAA morphology, dimension and other echocardiographic parameters by transesophageal echocardiography (TEE) in patients with embolic stroke of undetermined source (ESUS) and compare it with other etiological stroke subtypes without known AF. Methods: This was a single-Centre, observational study involving comparison of echocardiographic parameters including LAA morphology and dimension in ESUS patients (group A; n ¼ 30) with other etiological stroke subtypes i.e., TOAST (Trial of Org 10172 in Acute Stroke Treatment) class I-IV without AF (group B; n ¼ 30). Results: Complex LAA morphology was predominant in group A (18 patients in group A versus 5 patients in group B, p-Value ¼ 0.001). Mean LAA orifice diameter (15.3 þ 3.5 mm in group A versus 17 þ 2.0 mm in group B, p-Value ¼ 0.027) and LAA depth were significantly lower in group A (28.4 þ 6.6 mm in group A versus 31.7 þ 4.3 mm in group B, p-Value ¼ 0.026). Out of these three parameters only complex LAA morphology was found to be independently associated with ESUS [OR ¼ 6.003, 95% CI {1.225e29.417}, p ¼ 0.027]. Conclusion: Complex LAA morphology is a predominant feature in ischemic stroke patients with ESUS and may contribute to an increased risk of stroke in these patients.
ABSTRACT
Abstract The renin-angiotensin-aldosterone system (RAAS) plays a key role in diabetic nephropathy (DN). Angiotensin-II secreted during the RAAS pathway increases nephropathy. It stimulates oxidative stress which can quench nitric oxide. Reduced nitric oxide level aggravates Ang-II-induced vasoconstriction. Ang-II has also emerged as a central mediator of the glomerular hemodynamic changes that are associated with renal injury. Deletion of ACE2 is also noted due to increased Ang-II level which leads to the development of DN. We hypothesize that nephropathy caused by Ang-II in the periphery may be controlled by brain RAAS. ACE inhibitors and ARBs may show the renoprotective effect when administered through ICV without crossing the blood-brain barrier. DN was observed after 8 weeks of diabetes induction through alloxan. Administration of captopril and valsartan once and in combined therapy for 2 weeks, significantly reduced urine output, blood urea nitrogen, total protein in the urine, serum cholesterol, serum creatinine, serum triglycerides, and kidney/body weight ratio as compared to diabetic control rats. Further, combination therapy significantly increased the body weight and serum nitrate level as compared to diabetic control animals. However, increased ACE2 levels in the brain may reduce the sympathetic outflow and might have decreased the peripheral activity of Ang-II which shows beneficial effects in DN.

Abstract Introduction Diabetes mellitus is a metabolic disease associated with a rise in the level of blood glucose. Individuals with diabetes mellitus are more likely to develop hearing loss, tinnitus, and dizziness due to macro- and microvascular complications. The extent to which auditory and vestibular functions are impaired in individuals with type-2 diabetes mellitus is still under debate. Objective To systematically review studies focusing on auditory and vestibular functions in individuals with type-2 diabetes mellitus. Data Synthesis A search was conducted in the PubMed, MedlinePlus, Ingenta Connect and Google Scholar databases for articles published until June 2019. A total of 15,980 articles were primarily retrieved, 33 of which were shortlisted based on the inclusion criteria set by the investigators for the systematic review. Out of 33 full-length articles, 26 evaluated the functioning of the auditory system, while 7 evaluated the functioning of the vestibular system. Most studies related to auditory functioning reported a significant effect of type-2 diabetes mellitus on the peripheral auditory system, whereas studies on vestibular functioning reported no significant effect of diabetes mellitus on the functioning of the peripheral vestibular end-organ. Conclusion Overall, the results of various audiological and peripheral vestibular tests reveal distinctive peripheral and/or central auditory and vestibular end-organ impairments in individuals with type-2 diabetes mellitus.
ABSTRACT
Background & objectives: COVID-19 pandemic has triggered social stigma towards individuals affected and their families. This study describes the process undertaken for the development and validation of scales to assess stigmatizing attitudes and experiences among COVID-19 and non-COVID-19 participants from the community. Methods: COVID-19 Stigma Scale and Community COVID-19 Stigma Scale constituting 13 and six items, respectively, were developed based on review of literature and news reports, expert committee evaluation and participants’ interviews through telephone for a multicentric study in India. For content validity, 61 (30 COVID-19-recovered and 31 non-COVID-19 participants from the community) were recruited. Test–retest reliability of the scales was assessed among 99 participants (41 COVID-19 recovered and 58 non-COVID-19). Participants were administered the scale at two-time points after a gap of 7-12 days. Cronbach’s alpha, overall percentage agreement and kappa statistics were used to assess internal consistency and test–retest reliability. Results: Items in the scales were relevant and comprehensible. Both the scales had Cronbach’s ? above 0.6 indicating moderate-to-good internal consistency. Test–retest reliability assessed using kappa statistics indicated that for the COVID-19 Stigma Scale, seven items had a moderate agreement (0.4-0.6). For the Community COVID-19 Stigma Scale, four items had a moderate agreement. Interpretation & conclusions: Validity and reliability of the two stigma scales indicated that the scales were comprehensible and had moderate internal consistency. These scales could be used to assess COVID-19 stigma and help in the development of appropriate stigma reduction interventions for COVID-19 infected, and mitigation of stigmatizing attitudes in the community.
ABSTRACT
BACKGROUND: Many bacterial infections are associated with biofilm formation. It is one of the important virulent factors of E. coli in urinary tract, causing recurrent and drug resistant infections. Fecal E. coli colonize the urethra and spread up the urinary tract to the bladder and kidney. Type 1 fimbriae are surface located adhesion organelles of E. coli that are directly associated with adherence to the urinary tract. The present study was aimed to study biofilm production in E. coli isolated from urinary tract infection and to correlate it with expression of fimH gene and compare its sequences. METHOD: Total 150 urine samples were processed for isolation and identification of uropathogens. E. coli isolates were further processed for detection of biofilm by TCP method and screened for the presence of fimH gene by PCR using specific primers. The PCR products were purified and sequenced bidirectionally by Sanger dideoxy sequencing system using ABI 3500 Genetic analyzer. RESULTS: From the total 98 urine samples with significant bacteriuria, 77 E. coli were isolated out of which, 40 were positive for in vitro biofilm production. Among them11 were classified as strong biofilm producers and 29 as moderate. The fimH gene from E. coli isolates was amplified using specific primers and appeared as a band of about 508bp on agarose gel. It was noted that the fimH gene was detected in moderate and strong biofilm forming E. coli while absent in non biofilm isolates.The sequences showed 99% similarity with fim H gene of E coli. CONCLUSION: The high binding ability of fimH could result in increased bacterial binding to target cells and increased pathogenicity of E. Coli.
ABSTRACT
Cathranthus roseus also known as periwinkle, an ornamental plant contains several medicinal values, was found with the symptoms of little leaf and witches' broom at Shahjahanpur location with the incidence of up to 8%. The phytoplasma etiology was confirmed through scanning electron microscopy examination in all the four-leaf samples. Molecular analysis through PCR with universal primer pairs P1/P6 followed by nested PCR with R16F2n/R16r2 primers yielded ~1.2kbp amplicons in all the four symptomatic leaf samples. One amplicon was eluted, purified, sequenced, and used in BLASTn searches, which showed maximum identity of periwinkle isolate with several isolates of 16SrIX group of phytoplasma. Further, phylogenic analysis and in silico RFLP confirmed the association of 16SrIX-C subgroup phytoplasma in little leaf and witches broom plants which is the first report from India.

Background@#Nonhuman primates are used for research purposes such as studying diseases and drug discovery and development programs. Various clinical pathology parameters are used as biomarkers of disease conditions in biomedical research. Detailed reports of these parameters are not available for Indian-origin rhesus macaques. To meet the increasing need for information, we conducted this study on 121 adult Indian rhesus macaques (57 wild-sourced and 64 inhouse animals, aged 3–7 years). A total of 18 hematology and 18 biochemistry parameters were evaluated and reported in this study. Data from these parameters were statistically evaluated for significance amongst inhouse and wild-born animals and for differences amongst sexes. The reference range was calculated according to C28-A3 guidelines for reporting reference intervals of clinical laboratory parameters. @*Results@#Source of the animals and sex appeared to have statistically significant effects on reference values and range. Wild-born animals reported higher WBC, platelets, neutrophils, RBC, hemoglobin, HCT, MCV, and total protein values in comparison to inhouse monkeys. Sex-based differences were observed for parameters such as RBCs, hemoglobin, HCT, creatinine, calcium, phosphorus, albumin, and total protein amongst others. @*Conclusions@#Through this study, we have established a comprehensive data set of reference values and intervals for certain hematological and biochemical parameters which will help researchers in planning, conducting, and interpreting various aspects of biomedical research employing Indian-origin rhesus monkeys.

ABSTRACT
Background@#The genetic landscape of intestinal (INT) and pancreatobiliary (PB) type ampullary cancer (AC) has been evolving with distinct as well as overlapping molecular profiles. @*Methods@#We performed whole-exome sequencing in 37 cases of AC to identify the targetable molecular profiles of INT and PB tumors. Paired tumor-normal sequencing was performed on the HiSeq 2500 Illumina platform. @*Results@#There were 22 INT, 13 PB, and two cases of mixed differentiation of AC that exhibited a total of 1,263 somatic variants in 112 genes (2–257 variants/case) with 183 somatic deleterious variants. INT showed variations in 78 genes (1–31/case), while PB showed variations in 51 genes (1–29/case). Targetable mutations involving one or more major pathways were found in 86.5% of all ACs. Mutations in APC, CTNNB1, SMAD4, KMT2, EPHA, ERBB, and Notch genes were more frequent in INT tumors, while chromatin remodeling complex mutations were frequent in PB tumors. In the major signaling pathways, the phosphoinositide 3-kinase (PI3)/AKT and RAS/mitogen-activated protein kinase (MAPK) pathways were significantly mutated in 70% of cases (82% INT, 46% PB, p = .023), with PI3/AKT mutation being more frequent in INT and RAS/MAPK in PB tumors. Tumor mutation burden was low in both differentiation types, with 1.6/Mb in INT and 0.8/Mb in PB types (p =.217). @*Conclusions@#The exome data suggest that INT types are genetically more unstable than PB and involve mutations in tumor suppressors, oncogenes, transcription factors, and chromatin remodeling genes. The spectra of the genetic profiles of INT and PB types suggested primary targeting of PI3/AKT in INT and RAS/RAF and PI3/AKT pathways in PB carcinomas.

ABSTRACT
Introduction: Hemorrhoids are one of the most frequent anorectal disorders encountered by clinicians in day-to-day practiceand constitute about 50% of colorectal investigations. Stapled hemorrhoidopexy (SH) represents the first dramatic change inthe treatment of hemorrhoids. Since its introduction, some researchers have raised concerns about the recurrence rate as wellas patient satisfaction. Hence, the present study was carried out to evaluate recurrence rate and patient overall satisfactionwith SH procedure at a tertiary care center in North India.Materials and Methods: Ethical clearance was obtained at the start of the study from the Institutional Review Board. A totalof 100 patients with Grade III/IV hemorrhoids were included. SH was performed as per the standard procedures. Data werecollected on complications developed post operatively at different follow-ups and an overall patient satisfaction. The data werecoded and entered into Microsoft Excel 2010.Results: Post-operative complications we observed at the 1st week were bleeding and discharge in 5%, pain in 9%, and urinaryretention in 11% of enrolled cohorts. At 1 month, hematoma formation was observed in 7.3% of total remaining patients (n = 96)and 5.2% still had post-operative pain. At 6 months, pruritus and stenosis were witnessed in 4.3% and 1.1%, respectively, oftotal remaining patients (n = 93). Recurrence rate was found 4.3% at the end of 6 months. The overall complication rates at 1week, 1 month, and 6 months follow-up were 25%, 12.5%, and 9.7%, respectively.Conclusion: The findings of our study confirm that SH is associated with a high patient satisfaction and with a lesser postoperative complications. We conclude that SH is safe with many short-term benefits.
ABSTRACT
Introduction: Hemorrhoid disease therapy is effectively been treated with conventional excisional hemorrhoidectomy. Stapledhemorrhoidopexy (SH) revolutionized the traditional surgical approach by the introduction of the theory of dealing with the rectalmucosal prolapse by resecting a mucosal cylinder above the dentate line by means of mechanical stapling. It is a non-excisionalapproach for the surgical treatment of hemorrhoid disease.Materials and Methods: Ethical clearance was obtained from the institution. A total of 100 adult patients with Grade III/IVhemorrhoids indicated for surgery were recruited for the study purpose. Data collected were post-operative pain in the form ofVAS scale, immediate complications, duration, or length of stay in the hospital along with the time to resume work again. SPSS17.0 was used to carry out the analysis. All P < 0.05 were considered to be statistically significant.Results: The mean age of the study group was 45 ± 14.93 years. The mean length of hospital stays, postoperatively for 21%subjects, was mere 1 day; however, it was 2 days for the rest of population studied. The only complication was with 2% of thestudy population having excessive intraoperative bleeding. The mean time to return to work was 8 days. About 77% of thepatients resumed their work within 8 days of surgery.Conclusion: Within the given limitations of the study, we can conclude that SH is a successful procedure for Grade-III/IVhemorrhoids in terms of immediate post-operative complications, pain as well as the duration of hospital stay
ABSTRACT
Background: Incisional hernia is the second most common type of hernia after inguinal hernia. It is a complication of abdominal surgery, reported in up to 11% of patients generally and in up to 20% of those who developed post operative wound infection. The list of predictive factors associated with development of incisional hernia is obesity, diabetes mellitus, steroid, smoking, old age, malnutrition, COPD and type of incision.Methods: This was a hospital based cross sectional observational study carried out from February 2018 - October 2019 in surgery department of Dr. B.R.A.M. Hospital Raipur C.G, with diagnosis of incisional hernia. Total 100 patients were included in the study.Results: In present study the mean age of study subjects was 47.27±13.16 years. Around two-third 64% were females. 40% of perforation and 35% of LSCS cases later develop to Incisional hernia. Risk factors profile showed that 31% were alcoholic, 27% smokers, 48% pre-obese and 5% were obese. 36% were hypertensive, 48% diabetic, and 12% had constipation. 25% had prolonged cough, 35% had surgical site infection, 45% had anemia. Clinical presentation of study subjects showed that 63% had swelling, 33% had swelling and pain and 4% had obstruction.Conclusions: Incisional hernia is more common in female than males and in cases above the age of 45 years. It is more common in patients who underwent the previous surgery on an emergency basis especially in perforation and obstruction and LSCS cases. Risk factors associated with incisional hernia are smoker, alcoholic, obesity, hypertension, diabetes, constipation, prolong cough and anemia.
