Benefits of a laparoscopic approach for second colorectal resection after colectomy or proctectomy -a retrospective study.

BACKGROUND: A laparoscopic approach generally provides several benefits in patients who undergo colon or rectal surgery without jeopardizing oncological outcomes. However, there is a paucity of studies on comparative outcomes of laparoscopic versus open approaches for second primary colorectal lesions after colectomy or proctectomy. METHODS: From patients with colorectal disease who underwent surgery between 2008 and 2022 at our hospital, we collected 69 consecutive patients who had previous colorectal surgery for this retrospective study. Based on the second surgery approach (laparoscopic or open), patients were classified into the Lap (n = 37) or Op group (n = 32). Patients' baseline data and perioperative and postoperative outcomes were compared between the two groups. RESULTS: Four patients (11%) of the Lap group needed conversion to laparotomy. The intraoperative blood loss was lower in the Lap group than the Op group (median: 45 ml vs. 205 ml, p = 0.001). The time to first bowel movement was shorter in the Lap group than the Op group (median: 2.8 days vs. 3.6 days, p = 0.007). The operative time, frequencies of postoperative morbidities, and overall survival did not differ between the two groups. CONCLUSION: Laparoscopic surgery appeared feasible and beneficial for selected patients undergoing second colorectal resection after colectomy or proctectomy regarding blood loss and bowel function recovery without affecting other outcomes.

Association between Pet Ownership and Obesity: A Systematic Review and Meta-Analysis.

Obesity is a major risk factor for lifestyle-related diseases, including cardiovascular disease, type 2 diabetes, and hypertension. Several studies have investigated the association between pet ownership and obesity, but the findings have been inconsistent. This systematic literature review and meta-analysis assessed the association between pet ownership and obesity. Using PubMed and Scopus, we overviewed the literature published until December 2019 and selected pertinent data for meta-analysis. Two independent reviewers extracted the data. Pooled relative risks (RRs) with 95% confidence intervals (CIs) for obesity were calculated using the random-effects model with inverse-variance weighting. The 21 included articles were cross-sectional studies. Five publications (nine analyses) that reported adjusted RRs for BMI ≥ 25 were included in the meta-analysis. No significant association existed between pet ownership and obesity (pooled RR = 1.038; 95% CI, 0.922-1.167; I2 = 51.8%). After stratification by age group (children vs. adults), no significant association was detected (pooled RR = 0.844; 95% CI, 0.604-1.179; I2 = 64.1% vs. pooled RR = 1.099; 95% CI, 0.997-1.212; I2 = 25.2%). Similarly, no significant association was observed between dog ownership and obesity, indicating no association between pet ownership and obesity. However, no infer causation can be reported because all studies included in this meta-analysis were cross-sectional. Therefore, further prospective studies are needed.

Bacteremia induced by Bifidobacterium breve in a newborn with cloacal exstrophy.

Bifidobacterium breve is an effective probiotic agent used in the field of neonatology. Although B. breve has been considered safe, a case of B. breve bacteremia has been reported. The pathogenic mechanism underlying the bacteremia is unknown. Herein, we report a second case of B. breve bacteremia that developed in a neonate with multiple abdominal organ anomalies. Following surgical repair immediately after birth, B. breve treatment was started. After 1 week, the infant developed B. breve bacteremia following the onset of adhesive ileus. The bacteremia was thought to have been associated with an intestinal obstruction. A pediatric culture bottle is theoretically unsuitable for incubating B. breve because B. breve is an obligate anaerobic bacterium. It was, however, cultured from pediatric culture bottles in the present case, suggesting that pediatric culture bottles may be useful for procuring B. breve and for determining antimicrobial susceptibility for screening purposes in neonatal patients.

Validity of a Semi-Quantitative Food Frequency Questionnaire for Collegiate Athletes.

BACKGROUND: Food frequency questionnaires (FFQs) have been developed and validated for various populations. To our knowledge, however, no FFQ has been validated for young athletes. Here, we investigated whether an FFQ that was developed and validated to estimate dietary intake in middle-aged persons was also valid for estimating that in young athletes. METHODS: We applied an FFQ that had been developed for the Japan Public Health Center-based Prospective Cohort Study with modification to the duration of recollection. A total of 156 participants (92 males) completed the FFQ and a 3-day non-consecutive 24-hour dietary recall (24hDR). Validity of the mean estimates was evaluated by calculating the percentage differences between the 24hDR and FFQ. Ranking estimation was validated using Spearman's correlation coefficient (CC), and the degree of miscategorization was determined by joint classification. RESULTS: The FFQ underestimated energy intake by approximately 10% for both males and females. For 35 nutrients, the median (range) deattenuated CC was 0.30 (0.10 to 0.57) for males and 0.32 (-0.08 to 0.62) for females. For 19 food groups, the median (range) deattenuated CC was 0.32 (0.17 to 0.72) for males and 0.34 (-0.11 to 0.58) for females. For both nutrient and food group intakes, cross-classification analysis indicated extreme miscategorization rates of 3% to 5%. CONCLUSIONS: An FFQ developed and validated for middle-aged persons had comparable validity among young athletes. This FFQ might be useful for assessing habitual dietary intake in collegiate athletes, especially for calcium, vitamin C, vegetables, fruits, and milk and dairy products.

Simultaneous presentation of two cerebral aneurysms.

A 48-year-old woman experienced sudden onset of severe headache. Computed tomography showed subarachnoid hemorrhage (SAH) and intracerebral hematoma in the right frontal lobe. Digital subtraction angiography revealed three aneurysms in the anterior communicating artery (AcomA), the right posterior communicating artery (PcomA), and the right middle cerebral artery. The AcomA aneurysm was treated with endovascular coiling. However, her oculomotor nerve palsy was aggravated after the procedure. Embolization of the right PcomA aneurysm was conducted immediately and her oculomotor nerve palsy recovered completely 3 months later. Simultaneous presentation of multiple aneurysms with separate symptoms is rare. We speculate that the progressive oculomotor nerve palsy was caused by tiny enlargement or morphological change of the aneurysm caused by elevated blood pressure and pulsatile effect after SAH.

Endovascular repair of ruptured aneurysm arising from fenestration of the horizontal segment of the anterior cerebral artery: case report.

A 50-year-old man presented with an aneurysm arising from a fenestration of horizontal portion (A(1)) of the anterior cerebral artery manifesting as subarachnoid hemorrhage. Coil embolization was conducted and the aneurysm was occluded easily. Most reported cases of these types of aneurysms underwent direct surgery. Aneurysm arising from the A(1) fenestration is rare, but the present case shows that coil embolization can be an effective treatment modality. Three-dimensional rotational angiography and aneurysmography were helpful to characterize this complicated vascular structure.
