An Earlier First Meal Timing Associates with Weight Loss Effectiveness in A 12-Week Weight Loss Support Program

Recent studies have reported that meal timing may play an important role in weight regulation, however it is unknown whether the timing of meals is related to the amount of weight loss. This study aimed to examine the relationship between indices of meal timing and weight loss during weight loss intervention in adults. A 12-week weight loss support program was conducted for 97 adults (age: 47.6 ± 8.3 years, BMI: 25.4 ± 3.7 kg/m²). After the program, body weight decreased by −3.0 ± 2.7%. Only the start of the eating window was positively correlated with the weight change rate in both sexes (men: r = 0.321, p = 0.022; women: r = 0.360, p = 0.014). The participants were divided into two groups based on the start of the eating window as follows: the early group (6:48 ± 0:21 AM) and the late group (8:11 ± 1:05 AM). The weight loss rate in the early group was significantly higher (−3.8 ± 2.7%) than that in the late group (−2.2 ± 2.5%). The present results showed that the start of the early eating window was associated with weight loss and suggested paying attention to meal timing when doing weight loss.     

Radiological Demonstration of Spontaneous Rupture of a Pancreatic Pseudocyst into the Portal System

A rare case of a pancreatic pseudocyst that ruptured into the portal system is reported. Diagnosis was made preoperatively by a combination of radiological examinations. Details of the endoscopic retrograde cholangiopancreatogram, computed axial tomography and ultrasonically guided percutaneous transhepatic portography are presented.     

Pure laparoscopic right hepatectomy in the semi-prone position using the intrahepatic Glissonian approach and a modified hanging maneuver to minimize intraoperative bleeding

Purpose

Although laparoscopic liver resection has been widely adopted, performing a pure laparoscopic right hepatectomy remains a challenging procedure. The aim of this report is to evaluate the efficiency of a pure laparoscopic right hepatectomy (PLRH) in the semi-prone position using the intrahepatic Glissonian approach and a modified hanging maneuver.

Methods

Pure laparoscopic right hepatectomy was performed in the semi-prone position with the use of an intrahepatic Glissonian approach and modified hanging maneuver for patients with primary liver cancer (n = 3) and metastatic liver cancer (n = 1).

Results

The intraoperative total blood loss was only 95?C140 g (mean: 126.2 g). None of the patients required a blood transfusion, and no serious complications were encountered. The durations of the surgeries ranged from were 308 to 445 min (mean: 394.8 min). The postoperative hospital stay was 8?C11 days (mean 9.5 days).

Conclusion

Pure laparoscopic right hepatectomy in the semi-prone position using the intrahepatic Glissonian approach and a modified hanging maneuver is thus considered to be a safe modality, which minimizes intraoperative bleeding.     

Totally laparoscopic colectomy with intracorporeal anastomosis achieved using a laparoscopic linear stapler: experience of a single institute

Purpose  

Laparoscopic colonic surgery is now widely accepted. We assessed the safety and effectiveness of using a total intracorporeal surgical strategy to perform intracorporeal functional end-to-end anastomosis with an endoscopic linear stapler to treat colon cancer.     

Is “functional end-to-end anastomosis” really functional? A review of the literature on stapled anastomosis using linear staplers

Purposes

Anastomosis is one of the basic skills of a gastrointestinal surgeon. Stapling devices are widely used because stapled anastomosis (SA) can shorten operation times. Antiperistaltic stapled side-to-side anastomosis (SSSA) using linear staplers is a popular SA technique that is often referred to as “functional end-to-end anastomosis (FEEA).” The term “FEEA” has spread without any definite validation of its “function.” The aim of this review is to show the heterogeneity of SA and conventional hand-sewn end-to-end anastomosis (HEEA) and to advocate the renaming of “FEEA.”

Methods

We conducted a narrative review of the literature on SSSA. We reviewed the literature on ileocolic and small intestinal anastomosis in colonic cancer, Crohn’s disease and ileostomy closure due to the simplicity of the technique.

Results

The superiority of SSSA in comparison to HEEA has been demonstrated in previous clinical studies concerning gastrointestinal anastomosis. Additionally, experimental studies have shown the differences between the two anastomotic techniques on peristalsis and the intestinal bacteria at the anastomotic site.

Conclusions

SSSA and HEEA affect the postoperative clinical outcome, electrophysiological peristalsis, and bacteriology in different manners; no current studies have shown the functional equality of SSSA and HEEA. However, the use of the terms “functional end-to-end anastomosis” and/or “FEEA” could cause confusion for surgeons and researchers and should therefore be avoided.

     

Laparoscopic resection of ileal lipoma diagnosed by multidetector-row computed tomography

Intussusception is rare in adults and it is difficult to diagnose on admission. We present the case of a 43-year-old woman with the chief complaint of nausea and upper abdominal pain. Abdominal multidetector-row computed tomography showed ileo-ileal small bowel intussusception with an intraluminal soft tissue mass with attenuation numbers suggestive of a lipoma. The patient was treated with a laparoscopic-assisted extracorporeal partial resection of the small bowel including ileal lipoma, followed by a functional end-to-end anastomosis. Histologic diagnosis of the resected tumor, 2.4×2.0×2.0 cm, was an intestinal lipoma. This case serves as the basis of a review of small bowel intussusception in adults secondary to lipomas. It focuses on the utility of multidetector-row computed tomography and the cosmetic, physical, and economic benefits of laparoscopic surgery as well as the rarity of the disease.     

Elevated Von Willebrand factor propeptide for the diagnosis of thrombotic microangiopathy and for predicting a poor outcome

Thrombotic microangiopathy (TMA) is associated with vascular endothelial cell injury and is sometimes linked with poor outcome. Von Willebrand factor (VWF) propeptide (VWFpp) is considered to be a marker of vascular endothelial cell injury. The plasma levels of VWF, VWFpp, and thrombomodulin (TM) were evaluated for their use in the diagnosis of TMA in 75 patients with TMA. There were 30 TMA patients with marked decreases in ADAMTS13 (TMA/ADAMTS13) and 45 without the decrease (TMA/other). The plasma levels of TM, VWF, and VWFpp values were significantly high in patients with TMA, especially TMA/other group. The plasma levels of TM and VWFpp were significantly high in non-survivor with TMA. In the TMA/other group, the plasma levels of VWFpp were negatively correlated with ADAMTS13 activity. The plasma levels of TM correlated with the renal function, but the plasma levels of VWFpp did not. A ROC analysis indicated that VWFpp and TM were useful markers for the prediction of a poor outcome. These findings suggest that VWFpp is an useful marker for the diagnosis of TMA and for the prediction of poor outcome.     

The Inverse Correlation of Isoflavone Dietary Intake and Headache in Peri- and Post-Menopausal Women

This study investigated the relationship between headache and dietary consumption of a variety of nutrients in middle-aged women. This cross-sectional analysis used first-visit records of 405 women aged 40–59 years. The frequency of headaches was assessed using the Menopausal Health-Related Quality of Life Questionnaire. Of the 43 major nutrient intakes surveyed using the brief-type self-administered diet history questionnaire, those that were not shared between women with and without frequent headaches were selected. Multiple logistic regression analysis was used to identify nutrients independently associated with frequent headaches. After adjusting for background factors related to frequent headache (vasomotor, insomnia, anxiety, and depression symptoms), the estimated dietary intake of isoflavones (daidzein + genistein) (mg/1000 kcal/day) was negatively associated with frequent headaches (adjusted odds, 0.974; 95% confidence interval, 0.950–0.999). Moreover, the estimated isoflavone intake was not significantly associated with headache frequency in the premenopausal group, whereas it significantly correlated with that in the peri- and post-menopausal groups. Headache in peri- and post-menopausal women was inversely correlated with the dietary intake of isoflavones. Diets rich in isoflavones may improve headaches in middle-aged women.     

Downregulation of cytochrome P450scc as an initial adverse effect of adult exposure to diethylstilbestrol on testicular steroidogenesis

Reproductive toxicities and endocrine disruptions caused by chemicals in adult males are still poorly understood. It is our objectives to understand further details of the initial adverse effects leading severe testicular toxicities of a pharmaceutical endocrine disruptor, diethylstilbestrol (DES). Downregulations of both testicular regulatory proteins, such as the steroidogenic acute regulatory protein (StAR) and the peripheral benzodiazepine receptor (PBR), which play important roles in the transport of cholesterol into the mitochondria, and cytochrome P450 mediating the cholesterol side chain cleavage reaction (P450scc), were observed in the rat orally administered DES (340 μg/kg/2 days) for 2 weeks. We found that after only 1 week treatment with DES, the blood and testicular testosterone (TS) levels were drastically decreased without abnormalities of the StAR and PBR; however, the protein and mRNA levels of P450scc were diminished. Decrease in the conversion rate of cholesterol to pregnenolone was delayed in the in vitro assay using the testicular mitochondrial fraction from the rat treated with DES for 1 week. When the precursors in TS biosynthesis containing the testis were identified and determined by liquid chromatography‐mass spectrometry analysis, decreased levels of all precursors except cholesterol were observed. In conclusion, suppressed cytochrome P450scc expression in adult male rat was identified as an initial target of DES in testicular steroidogenesis disorder leading reproductive toxicities. © 2013 Wiley Periodicals, Inc.
