Abstract
Impaired expression of heat shock proteins (HSPs) and increased oxidative stress may contribute to the pathophysiology of diabetes by disrupted tissue protection. Acute exercise induces oxidative stress, whereas exercise training up-regulates endogenous antioxidant defenses and HSP expression. Although diabetic nephropathy is a major contributor to diabetic morbidity, information regarding the effect of HSPs on kidney protection is limited. This study evaluated the effects of eight-week exercise training on kidney HSP expression and markers of oxidative stress at rest and after acute exercise in rats with or without streptozotocin-induced diabetes. Induction of diabetes increased DNA-binding activity of heat shock factor-1, but decreased the expression of HSP72, HSP60, and HSP90. The inflammatory markers IL-6 and TNF-alpha were increased in the kidney tissue of diabetic animals. Both exercise training and acute exercise increased HSP72 and HSP90 protein levels only in non-diabetic rats. On the other hand, exercise training appeared to reverse the diabetes-induced histological changes together with decreased expression of TGF-beta as a key inducer of glomerulosclerosis, and decreased levels of IL-6 and TNF-alpha. Notably, HSP72 and TGF-beta were negatively correlated. In conclusion, impaired HSP defense seems to contribute to kidney injury vulnerability in diabetes and exercise training does not up-regulate kidney HSP expression despite the improvements in histopathological and inflammatory markers.

Abstract
INTRODUCTION Breast cancer represents a major public health problem in women worldwide. For many cancers, serum tumour markers play an important role in patient treatment and monitoring. Isocitrate dehydrogenase enzyme is also used as a biomarker for various types of cancer. AIM The purpose of this study was to determine serum Isocitrate dehydrogenase-2 (IDH-2) enzyme activity in breast cancer patients (pre and post chemotherapy) and also correlate the changes in enzyme activity with stages of cancer and control groups. MATERIALS AND METHODS In this case-control study, histologically confirmed 40 female patients aged 28-80 years who fulfilled the criteria for diagnosis of invasive breast cancer were selected in our study groups from surgery outpatient department of SS Hospital, BHU, Varanasi, India, and 40 healthy age matched females were selected between October 2013 to July 2015. The estimation of serum IDH-2 enzyme activity in before and after two cycles of neoadjuvant chemotherapy patients was performed by spectrophotometry assay. RESULTS The mean serum IDH-2 activity in cases (Mean±SD) was significantly more than control group (p<0.001). The mean serum IDH-2 activity in cases was significantly decrease after neo-adjuvant chemotherapy (p=0.019). In stage II pre chemotherapy patients serum IDH-2 activity was higher than post chemotherapy (p<0.05), but in stage III the correlation between pre and post chemotherapy patients serum IDH-2 activity was not significant (p-value>0.05). CONCLUSION The serum IDH-2 can be a potential biomarker in breast carcinoma and can be used for prognosis and monitoring the chemotherapy response of the patients.

Abstract
BACKGROUND Clostridium difficile infection (CDI) is associated with increased mortality in inflammatory bowel disease (IBD), but the risk of colectomy is variable and has not been adequately studied. AIM To perform a systematic review and meta-analysis to assess the impact of CDI on colectomy risk in IBD. METHODS Multiple databases were searched systematically for observational studies reporting colectomy risk in IBD, stratified by the presence of CDI, and the duration of follow-up (short term 3 months, and long term at least 1 year). Weighted summary estimates were calculated using generalised inverse variance with random-effects model. Study quality was assessed using the Newcastle-Ottawa scale. RESULTS Twelve observational studies were identified and included 35 057 IBD patients with CDI, and 929 259 without CDI. CDI did not increase the short-term colectomy risk in IBD patients overall (10 studies) (OR: 1.35; 95% CI: 0.68-2.67), or in patients with ulcerative colitis (nine studies) (OR: 1.20; 95% CI: 0.39-3.76). In contrast, CDI was associated with higher long-term colectomy risk in patients with IBD overall (five studies) (OR: 2.23; 95% CI: 1.18-4.21), and in patients with ulcerative colitis (four studies) (OR: 2.96; 95% CI: 1.19-7.34). The results were stable in subgroups stratified by recruitment period, hospitalisation status and geographical location. All studies were at least of moderate quality. The results were limited in the ability to compare IBD severity and the type of anti-microbial therapy. CONCLUSION Based on 12 observational studies with at least moderate quality, Clostridium difficile infection appears to increase colectomy risk in IBD in the long- but not short- term.

Abstract
The postbulbar segment also known as the distal duodenum is a separate clinical entity in terms of the intrinsic pathologies of this region and its varied anatomical relations. The common bile duct and the pancreatic duct open through the major papilla, which marks the beginning of this segment. Distal duodenal obstruction can be defined as a clinicoradiological entity that is characterized by features of gastric outlet obstruction with recurrent bilious vomiting and a radiological evidence of postbulbar obstruction. A Medline search for distal duodenal obstruction revealed 1409 entries, mostly in the form of case reports. In the last 10 years, 310 cases are reported. Clinical features like abdominal pain, nausea, and vomiting are non-specific and quite similar to gastric outlet obstruction. Clinical findings are also non-specific and do not aid in diagnosis. Laboratory findings also do not add much. Contrast-enhanced CT scan and MR enterography are diagnostic modalities of choice. Distal duodenal obstruction is a clinical entity that has a wide list of differential diagnosis which requires due consideration in terms of its management and follow-up. Most of these lesions require adequate workup with the help of a multidisciplinary team consisting of radiologists, gastroenterologists, and pathologists to adequately diagnose and stage the disease before a treatment plan is formulated. A thorough knowledge is a must regarding the treatment options available for each of the conditions so that the management can be personalized leading to better results.

Abstract
BACKGROUND Infectious enteritis is a commonly identified risk factor for irritable bowel syndrome (IBS). The incidence of Clostridium difficile infection (CDI) is on the rise. However, there is limited information on post-infectious IBS (PI-IBS) development following CDI and the host- and infection-related risk factors are not known. AIM To determine the incidence and risk factors for PI-IBS following CDI. METHODS A total of 684 cases of CDI identified from September 2012 to November 2013 were surveyed. Participants completed the Rome III IBS questionnaire and details on the CDI episode. Predictive modelling was done using logistic regression to evaluate risk factors for PI-IBS development. RESULTS A total of 315 CDI cases responded (46% response rate) and 205 were at-risk (no pre-CDI IBS) for PI-IBS development. A total of 52/205 (25%) met the Rome III criteria for IBS ≥6 months following CDI. IBS-mixed was most common followed by IBS-diarrhoea. In comparison to those without subsequent PI-IBS, greater percentage of PI-IBS patients had CDI symptoms >7 days, nausea, vomiting, abdominal pain during CDI, anxiety and a higher BMI. Using logistic regression, CDI symptoms >7 days [Odds ratio (OR): 2.96, P = 0.01], current anxiety (OR: 1.33, P < 0.0001) and a higher BMI (OR: 1.08, P = 0.004) were independently associated with PI-IBS development; blood in the stool during CDI was protective (OR: 0.44, P = 0.06). CONCLUSIONS In this cohort study, new-onset IBS is common after CDI. Longer CDI duration, current anxiety and higher BMI are associated with the diagnosis of C. difficile PI-IBS. This chronic sequela should be considered during active management and follow-up of patients with CDI.
