Objective:Overweight and obesity prevalence has increased in low-income countries.This study systematically reviewed the obesity trend,disparities,and prevention and control efforts in Nepal. Methods:We searched PubMed and Google Scholar for articles and reports published between January 1,2004 and December 31,2022.Additional information on National policies and programs related to obesity prevention was retrieved from governmental websites and consultation with relevant experts.Overweight and obesity were defined using the World Health Organization body mass index cut points.Thirty-two studies and reports were included. Results:Overall,overweight and obesity rates increased in all groups in Nepal although nationally representative data remained limited.The combined overweight and obesity(OW/OB)and obesity rates in women aged 15-49 years increased from 8.5％to 22.2％and from 0.9％to 5.1％between 2006 and 2016,respectively.OW/OB and obesity rates in men were 17.1％and 2.5％based on data from the 2016 Demographic and Health Survey.OW/OB rate in under-five children increased from 0.6％to 2.8％between 2006 and 2016.Obesity rates for school-age(5-9 years)boys and girls in 2016 were 2.4％and 2.8％,respectively,and were 1.1％and 1.4％for male and female adolescents aged 10-19 years,respectively.OW/OB prevalence was much higher among women,residents in urban areas and central provinces,and in higher socioeconomic status groups.Projected prevalence of OW/OB and obesity for 2030 in adults aged 15-49 was 44.7％and 8.3％,respectively,while it was 2.2％for OW/OB in preschool children.Policies and direct interventions that specifically focused on obesity prevention and control are limited. Conclusions:OW/OB prevalence in Nepal has increased during the past 1.8 decades,disproportionately affecting population groups.Existing interventions mostly focused on undernutrition with some indirect implications for obesity prevention.In the future,Nepal needs to develop population-based programs for obesity prevention.

Objective:To summarize the clinicopathologic features and clinical diagnosis and treatment experience of retroperitoneal paraganglioma.Methods:This study retrospectively analyzed the clinical, pathological and follow-up data of 39 patients admitted to the First Affiliated Hospital of Xi'an Jiaotong University from 1 Oct 2012 to 1 Oct 2022 for retroperitoneal paragangliomas undergoing resection.Results:There were 19 males and 20 females with tumor being functional in 11 cases (28%) and non-functional in 28 cases (72%). CT angiography showed that the tumors were distributed around the abdominal aorta and inferior vena cava in most cases. All 39 patients underwent tumor rescetion.Patients in laparoscopic group had shorter operation time and postoperative hospital saty compared with open sugery [(135±66)min vs. (194±67)min, t=-2.529, P=0.016; (6.6±2.2)d vs.(9.6±4.8)d, t=-2.096, P=0.043], while there was no statistically significant difference between the two groups in terms of intraoperative blood loss [(152±151)ml vs. (361±608)ml, t=-1.169, P=0.250]. There were no major postoperative complications in the laparoscopic group, and pulmonary infection in 1 case and intestinal obstruction in 1 case in the open group. Thrity-six cases were followed up, ranging from 2 to 115 months, 1 patient in the laparoscopic group died 1 year after surgery due to recurrence and metastasis. In the open group, 1 case recurred 2 years later and was discharged after the second operation, and 1 case died of recurrence 2 years after surgery. Conclusions:Surgery is indicated for retroperitoneal paraganglioma. Adequate perioperative management is the key to the success of the operation. Laparoscopic surgery is superior to open surgery in terms of operation time and postoperative recovery .

The Omicron family of SARS-CoV-2 variants are currently driving the COVID-19 pandemic. Here we analyzed the clinical laboratory test results of 9911 Omicron BA.2.2 sublineages-infected symptomatic patients without earlier infection histories during a SARS-CoV-2 outbreak in Shanghai in spring 2022. Compared to an earlier patient cohort infected by SARS-CoV-2 prototype strains in 2020, BA.2.2 infection led to distinct fluctuations of pathophysiological markers in the peripheral blood. In particular, severe/critical cases of COVID-19 post BA.2.2 infection were associated with less pro-inflammatory macrophage activation and stronger interferon alpha response in the bronchoalveolar microenvironment. Importantly, the abnormal biomarkers were significantly subdued in individuals who had been immunized by 2 or 3 doses of SARS-CoV-2 prototype-inactivated vaccines, supporting the estimation of an overall 96.02% of protection rate against severe/critical disease in the 4854 cases in our BA.2.2 patient cohort with traceable vaccination records. Furthermore, even though age was a critical risk factor of the severity of COVID-19 post BA.2.2 infection, vaccination-elicited protection against severe/critical COVID-19 reached 90.15% in patients aged ≽ 60 years old. Together, our study delineates the pathophysiological features of Omicron BA.2.2 sublineages and demonstrates significant protection conferred by prior prototype-based inactivated vaccines.

Objective:To construct a Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression.Methods:Convenience sampling was used to select 25 experts from fields such as psychiatric nursing, psychiatric management, and rehabilitation treatment as the subject of the consultation. On the basis of literature review and clinical experience, the research group used the Delphi method to conduct two rounds of consultation with 25 experts, forming a Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression. The enthusiasm of experts was evaluated using the effective response rate of the questionnaires. The authority level of experts was assessed using an authority coefficient. The concentration of expert opinions was evaluated using the mean of item importance assignment and coefficient of variation. The degree of coordination of expert opinions was represented by the Kendall coordination coefficient.Results:The effective response rates of the two rounds of consultation questionnaires were all 100%, with expert authority coefficients of 0.890 and 0.904, and the Kendall coordination coefficients of expert opinions of 0.247 and 0.203 ( P<0.05) . The Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression was constructed, which included 10 dimensions and 38 items. Conclusions:The Discharge Preparation Service Demand Assessment Scale for Psychiatric Patients with Depression is scientific and reliable, which can provide a basis for clinical nurses to evaluate the discharge preparation service demands of psychiatric patients with depression.

Objective:To explore the intention of exclusive breastfeeding and its influencing factors within six months after delivery of pregnant women in the third trimester of pregnancy in Xi'an.Methods:From January to February 2019, convenience sampling was used to select 2 671 pregnant women in the third trimester of pregnancy who underwent regular obstetric examinations in Obstetrics Clinic of five hospitals in Xi'an for a cross-sectional survey. Pregnant women were surveyed by means of a field survey using a self-designed Exclusive Breastfeeding Intention of Pregnant Women in the Third Trimester Questionnaire. Multivariate Logistic regression was used to analyze the influencing factors of the intention of exclusive breastfeeding among pregnant women in the third trimester. A total of 2 671 questionnaires were distributed, 2 479 valid questionnaires were recovered, and the valid recovery rate was 92.8% (2 479/2 671) .Results:A total of 60.8% (1 507/2 479) of pregnant women planned to exclusively breastfeed within 6 months of delivery. Pregnant women in the third trimester of pregnancy whose husbands ( OR=2.950, 95% CI: 2.097-4.066) and family members ( OR=2.171, 95% CI: 1.571-3.000) supported exclusive breastfeeding had high intention to exclusively breastfeed, and those who participated in breastfeeding courses had a high intention to exclusively breastfeed ( OR=1.436, 95% CI: 1.199-1.719) . Conclusions:More than half of third-trimester women plan to exclusively breastfeed within six months postpartum. Husband and family support and enrolment in breastfeeding classes increase the intention of pregnant women to exclusively breastfeed. Prenatal breastfeeding courses should be carried out to raise the awareness of pregnant women and family members about exclusive breastfeeding, and focus on the support of husbands and family members for exclusive breastfeeding, so as to increase the exclusive breastfeeding rate within six months after delivery.

BACKGROUND:The peri-implant bone absorption is closely related to the repair effect. OBJECTIVE:To compare the effects of three kinds of dental implant systems on the peri-implant bone absorption. METHODS:116 patients who underwent the dental implant systems were col ected, including 46 cases with 3I implant system, 40 cases with ITI implant system and 30 cases with BLB implant system. The peri-implant bone absorption, sulcus bleeding index and periodontal probing depth of three groups were detected at 1, 3, 6, 9 and 12 months after implantation, respectively. RESULTS AND CONCLUSION:The peri-implant bone absorption of three groups within 1 year after implantation was in a rise, and the bone absorption of BLB group was significantly higher than that of ITI and 3I groups at 3 and 12 months after implantation (P<0.05). Compared with the natural teeth, the gingival sulcus bleeding index of three groups were al increased at different time points after implantation;the gingival sulcus bleeding index of BLB group was significantly higher than that of natural teeth at 6 months after implantation (P<0.05);the gingival sulcus bleeding index of three groups were significantly higher than that of natural teeth at 9 months after implantation (P<0.05). The periodontal probing depth of three groups showed an ascending trend at 6 months after implantation;the periodontal probing depth of three groups was higher than that of natural teeth at different time points after implantation, which exhibited significant differences at 6 and 9 months after implantation (P<0.05). In conclusion, three kinds of dental implant systems exhibit differet effects on the peri-implant bone absorption, but al achieve excel ent clinical efficacies.
