Gastroenterology and Hepatology From Bed to Bench Journal, Volume:17 Issue: 2, Spring 2024, PP 206 -211Background
Chronic granulomatous disease (CGD) is a rare disorder normally diagnosed in infancy.
Case presentationA 27-year-old man admitted with non-specific symptoms of CGD first underwent endoscopy and colonoscopy procedures as primary evaluation of clinical presentation. Eighteen months after the first admission, he was referred to the emergency department for hematemesis and critical situations, such as a severe anemic with Hgb= 2.6 mg/dl. Due to this clinical presentation, emergently critical management was done, and endoscopic investigation showed some ulcers and deformities at the duodenal bulb and jejunum. Other imaging procedures, such as sonography and abdominal CT scans, revealed splenomegaly. He underwent splenectomy, and after that, endoscopic treatment with balloon TTS dilation was scheduled, but this procedure failed. So, we decided to do a gastro-jujenostomy that alleviated the clinical symptoms. After nine months, he was referred to GOO, and endoscopic evaluation showed giant ulceration with severe stricture in the duodenum and a polyp in the jejunostomy. Finally, Based on clinical presentation and pathologic evidence of biopsies, the patient approached CGD as the final diagnosis.
ConclusionStep-by-step rule out of different highly suspicious diseases may result in a definite CGD diagnosis, and rapid management of these patients may increase the chance of survival.

Context:
The gastrointestinal microbiota is pivotal in cardiovascular surgery outcomes. This systematic review and meta-analysis aims to synthesize current evidence regarding the impact of gut microbiota on postoperative metabolomic markers and patient recovery.
Evidence Acquisition:
Following PRISMA guidelines, a comprehensive search was conducted across MEDLINE, Web of Science, EMBASE, Scopus, and Cochrane's CENTRAL databases. Studies involving patients undergoing cardiovascular surgery and reporting on gut microbiota were included. Data extraction focused on study characteristics and metabolomic outcomes. The Newcastle-Ottawa Scale (NOS) assessed the risk of bias.
ResultsSix studies met the inclusion criteria, involving 530 patients. Meta-analysis revealed that a beneficial gut microbiota profile is associated with less increase in LDL cholesterol (Mean Difference: 14.4 mg/dL, SE: 0.816), a smaller decrease in HDL cholesterol (Mean Difference: -4.9 mg/dL, SE: 0.437), a lower rise in triglycerides (Mean Difference: 11.2 mg/dL, SE: 0.552), and a reduced elevation in CRP levels (Mean Difference: 2.4 mg/L, SE: 0.291) post-surgery. The overall risk of bias ranged from moderate to low across studies.
ConclusionThe findings suggest that gut microbiota composition significantly influences lipid metabolism and inflammatory responses post-cardiovascular surgery. A favorable microbiota profile may provide a protective effect against postoperative complications. These insights underline the potential for microbiota-modulating interventions in enhancing cardiovascular surgery outcomes.

Chlorine-containing bleach, as a common disinfectant, can cause mild to severe symptoms from nasal irritation to life-threatening conditions such as acute respiratory distress syndrome (ARDS). However, the toxicity level of chlorine gas depend on the duration and concentration of exposure. Herein, we describe the case of a 44-year-old man admitted to the emergency department with a chief complaint of severe shortness of breathing and hemoptysis following an accidental, short- time exposure to a chlorine-containing bleach. Because the life-threatening condition, he was transferred to Intensive Care Unit (ICU) and received mechanical ventilation along with a corticosteroid agent and antibiotic therapy. Despite limited data on management of the severe complications of the exposure, the patient successfully recovered after 4 days.

BACKGROUND
Digoxin is a drug for ventricular rate control in atrial fibrillation (AF). The major challenge in digoxin therapy is to adjust the appropriate concentration range for this drug due to its narrow therapeutic index. Unique physiochemical properties of drinking water affect the pharmacological actions and delivery of drugs to the body whether they are administered orally, topically, or by injection. The aim of this study was to evaluate water hardness effect on digoxin therapy in an experimental rat model.
METHODS48 rats weighing 200-220 g were randomly assigned to three groups that received drinking water with 50, 400, and 800 mg/l hardness degrees for 28 days. Then each group was assigned into two groups. One received digoxin 0.2 mg/kg a day orally for four days. The other group received normal saline (as control group). Continuous recording of electrocardiogram (ECG) was performed by PowerLab system (AD Instruments Company) before and day 4 of digoxin treatment. Then serum samples were collected and assessed for digoxin, sodium, potassium, calcium, magnesium, blood urea nitrogen (BUN), and creatinine levels.
RESULTSWater hardness in the range of 50-800 mg/l had no effect on serum digoxin levels
(P > 0.050), but consuming hard drinking water (400 and 800 mg/l) could increase serum calcium levels and then cause mortality (37.5% in both groups), following changes in ECG due to digoxin consumption.CONCLUSIONConsuming hard drinking water probably interferes with digoxin pharmacodynamics in the way of toxicity induction.

Background
Acute kidney injury (AKI) is one of the serious complications of cardiac surgery. It is worsened when accompanied by low cardiac output syndrome.
ObjectivesIn this study, we compared kidney function based on the KDIGO criteria in isolated on-pump and off-pump coronary artery bypass graft (CABG) surgery.
MethodsIn this cohort study, 52 patients with LCOS were enrolled after on-pump (28 patients) and off-pump (24 patients) CABG. In the first six hours after ICU entrance, blood samples were taken for serum creatinine based on routine. For determining AKI after surgery, we used the KDIGO criteria as a primary endpoint. Also, some clinical parameters were recorded before, during, and after surgery. The data were analyzed by SPSS software, version 24, using paired and independent t-test, ANOVA, and Pearson correlation test and non-parametric tests such as Mann-Whitney and Kruskal-Wallis tests at a significance level of P < 0.05.
ResultsThere was no significant difference in age (P = 0.3) and gender (P = 0.57) between the two groups. Among cardiac disease risk factors, only hypertension (P = 0.02) had a significant difference between the two groups, but AKI in patients with hypertension did not show a significant difference (P = 0.09). In paraclinical parameters, serum creatinine showed a significant difference before and after surgery in on-pump (P < 0.001) and off-pump (P = 0.007) groups. Also, this parameter had a significant difference at 6 h, 12 h, 24 h, and 48 h after surgery between the on-pump and on-pump groups. The AKI incidence showed a significant difference between the two groups (P < 0.001).
ConclusionsThe incidence of AKI was more in on-pump patients than in off-pump patients. Also, a significant difference was observed between their clinical parameters. Thus, to improve the patients’ clinical outcomes and lower the health costs, we suggest that patients with a high risk of LCOS be followed up after CABG, especially on-pump CABG.

ابهام در فلسفه تربیتی و نپرداختن به شرایط موردنیاز از یکسو، نبود زمینه و دغدغه کافی برای نهادینه کردن فلسفه تربیتی در نظام آموزشی و شیوع بیمارگونه ی گرایش به ایجاد مهارت تست زنی در دانش آموزان، مخاطراتی را در سطوح فردی و اجتماعی به همراه دارد. این تحقیق، با تکیه بر روش پدیدارشناسی به تحلیل ادراک و تجربه زیسته، با انجام مصاحبه نیمه ساختاریافته با 15 نفر از رتبه های برتر در کنکور کارشناسی، کارشناسی ارشد و متخصصین پرداخته شد تا تاثیر ثبت نام در کلاس های موسوم به تست زنی بر عملکرد دانش آموزان در آزمون کنکور سراسری، مورد واکاوی قرار گیرد. یافته ها بیانگر 4 مضمون کلی، افت سواد دانش آموختگان با 7 زیر مضمون، نخبه های کم درآمد با 4 زیر مضمون، تضعیف تربیت رسمی با 4 زیر مضمون و مضمون نابرابری اجتماعی با 9 زیر مضمون است. نتایج نشان می دهد، هرچند استفاده از این کلاس ها، احتمال موفقیت در آزمون های چندگزینه ای را افزایش می دهد، اما به شکل گیری و تشدید نابرابری اجتماعی انجامیده است. به دیگر سخن، ترویج بیمارگونه استفاده از کلاس های کنکور زمینه را برای ناکارآمدتر شدن آموزش وپرورش رسمی آماده کرده و درنتیجه نادیده گرفته شدن استعدادهای بسیاری که به دلایلی نظیر مادی، اجتماعی و فرهنگی، توانایی استفاده از این نوع آموزش ها ندارند را به دنبال داشته و توان قبولی در رشته های پر درآمد و پرطرفدار را از آن ها سلب خواهد کرد. به نظر می رسد این موارد منجر به نادیده گرفته شدن بخش از توان بالقوه ی جامعه و تشدید نابرابری اجتماعی شده است؛ این امر اهمیت بازاندیشی برای جلوگیری از دامنه دار شدن مخاطرات ذکر شده را بیش از پیش نمایان می سازد.
کلید واژگان: تربیت سایه, موفقیت در کنکور, عدالت اجتماعی, تست زنی, تدریس برای آزمونAmbiguity in the philosophy of education and failure to meet the requirements, on the one hand, and the lack of background and anxiety for the institutionalization of educational philosophy in the educational system and the illiterate outbreak of the tendency to develop testing skills in the students on the other hand has risks at the individual and social levels. This study conducted a semi-structured interview with 15 of the top rankings in undergraduate, graduate and postgraduate undergraduate, postgraduate and specialist enrollments by analyzing perceptions and experiences, based on phenomenological method so that the effect of registration in so-called test classes on student performance the exam will be interpreted in a national exam. The findings revealed 4 general themes, the drop in literacy of graduates with 7 sub-themes, low-income elites with 4 sub-themes, the weakening of formal education with 4 sub-themes and the theme of social inequality with 9 subsamples. The results show that, although the use of these classes increases the probability of success in multiple-choice tests, it has led to the formation and intensification of social inequality. In other words, the ill-fated promotion of the use of pre-school classes has paved the way for the ineffectiveness of formal education and, as a result of neglecting the many talents who have no such ability to use these kinds of training for reasons such as material, social and cultural, ability to admit to high-paying and popular courses. It seems that this has led to a neglect of the potential of the community and the intensification of social inequality; it doubles the need for rethinking to prevent the deepening of the hazards enumerated.
