Association of Dietary Energy Intake With Constipation Among Men and Women: Results From the National Health and Nutrition Examination Survey.

Background: Previous studies supported that dietary factor was associated with constipation, but the relationship between dietary energy intake and constipation has not been well-studied. Therefore, we aimed to evaluate the prevalence and correlation between energy intake and constipation among men and women. Methods: These observational analyses included 12,587 adults (≥20 years) from the 2005-2010 cycles of the National Health and Nutrition Examination Surveys (NHANES). Constipation was defined as Bristol Stool Scale Type 1 (separate hard lumps, like nuts) or Type 2 (sausage-like but lumpy). Total energy intake was obtained from the two 24-h dietary recalls and averaged. We used the logistic regression model in Generalized Linear Model (GLM) function, controlling demographic, lifestyle, and dietary factors, to estimate the association between energy intake and constipation among men and women. Results: The overall weighted incidence of constipation in this research was 7.4%, the incidence in women and men was 10.4 and 4.3%, respectively. After multivariable adjustment, middle energy consumption correlated with decreased risk of constipation in men (OR:0.5, 95% CI:0.29-0.84), and lower-middle energy intake increased the constipation risk in women (OR: 1.56, 95% CI: 1.15-2.13). High energy consumption was not associated with increased or decreased constipation risk. Conclusions: To our knowledge, this is the first research to investigate the association between energy intake and constipation; the study demonstrates that appropriate energy consumption can help reduce the risk of constipation in men, and relatively low energy intake is associated with increased constipation risk in women.

Solitary metastasis to the skin and colon from gastric cancer after curative gastrectomy and chemotherapy: A case report.

RATIONALE: Gastric cancer usually spread via blood circulation to liver, lung, bone, and kidney after recurrence, but it is extremely rare in clinical practice that gastric carcinoma metastasizes to the skin and colon without metastasis to common sites like liver or lung. PATIENT CONCERNS: A 57-year-old man was admitted to the hospital with altered bowel habit and hematochezia for 2 weeks. DIAGNOSES: The patient was diagnosed with advanced gastric cancer at stage IIIA (pT3N2M0) two and a half years ago. Cutaneous metastasis from gastric cancer was confirmed by cutaneous biopsy 2 years following curative gastrectomy. Unfortunately, colonic metastasis from gastric cancer was found by PET-CT 6 months after the diagnosis of cutaneous metastasis. INTERVENTIONS: The patient was given chemotherapy with docetaxel, cisplatin, and 5-fluorouracil for the skin metastasis. Right hemicolectomy was performed when the malignant tumor of the colon was found, in order to relieve the symptom, and improve the quality of life. OUTCOMES: The patient was treated with chemoradiotherapy in a local hospital, the peritoneal carcinomatosis occurred 5 months after the second operation, and died 9 months after the diagnosis of colonic metastasis. LESSONS: Our case represents a rare condition that solitary cutaneous and colonic metastasis from gastric cancer can occur after surgical resection and systemic chemotherapy. Its unique clinicopathological features can extend our insights on gastric cancer, and it may provide clinicians with some positive clinical experience for identifying and treating this disease.

Acute toxicities and sublethal effects of some conventional insecticides on Trichogramma chilonis (Hymenoptera: Trichogrammatidae).

The acute toxicity of 10 conventional insecticides to adult of Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae) was bioassayed by membrane method, and then their sublethal effects on the parasitoid were evaluated in the laboratory. Based on sublethal concentration (LC30) values at 8 h after treatment, we determined that adult T. chilonis were the most susceptible to chlorfenapyr, followed by fipronil, spinosad, avermectins, beta-cypermethrin, and cartap, with lethal concentration (LC)30 values of 0.3133, 0.3269, 1.5408, 3.2961, 6.1469, and 9.021 mg/liter, respectively. The field-recommended concentrations of chlorfluazuron, indoxacarb, Bacillus thuringiensis, and tebufenozide caused <30% mortality of treated adults; therefore, they were used to evaluate sublethal effects on the parasitoid. After treatment with sublethal concentration of fipronil and avermectins, the longevity of treated females (1.2 and 1.6 d) was significantly shortened and fecundity (34.7 and 1.6) was remarkably decreased; consequently, the life-table parameters (R0, r(m), lambda, and T) of T. chilonis were statistically lower than those in the control. Cartap and spinosad also reduced longevity (8 and 7.9 d) and fecundity (110.77 and 117.2) of treated adults, but cartap enhanced the female percentage of F1 offspring (61.6%), resulting a statistical higher R0, r(m), and lambda of treated T. chilonis. In contrast, chlorfluazuron and tebufenozide increased longevity (16.4 and 15.4 d) and fecundity (248 and 256.9) of treated adults but slightly decreased the female percentage of F1 offspring (31.4 and 38.1%). Although chlorfenapyr showed no adverse influence on longevity and fecundity, it remarkably reduced the female percentage of F1 offspring (13.5%), leading to a lower R0, r(m), and lambda of treated T. chilonis. Indoxacarb, B. thuringiensis, and beta-cypermethrin had no obvious sublethal effects on the longevity and fecundity of treated adults. Based on these results, we consider B. thuringienesis, chlorfluazuron, indoxacarb, beta-cypermethrin, and tebufenozide safe to T. chilonis, suggesting that these insecticides are compatible with this parasitoid when being used in the field. However, fipronil, chlorfenapyr, spinosad, and avermectins were very harmful to T. chilonis. Timing of application of these insecticides was critical.
