Objective:To explore the decision-making experience of patients undergoing abdominoplasty in our country.Methods:A semi-structured interview was conducted with patients suffering from postpartum abdominal wall laxity who were treated at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June to August 2023. The data were sort and analyzed using the Clolaizzi 7-step analysis method for thematic description.Results:A total of 15 patients, aged 29-53 years, were included in the study. 11 had a college education or higher, while 4 had less than a college education.Thirteen were married and two were divorced. According to the interview data, four themes were extracted: (1) negative perceptual experiences; (2) decision-making dilemmas; (3) peer support; (4) a physician-led decision-making model. According to the interview, the main decision-making dilemma faced by patients with postpartum abdominal wall laxity was lack of information and family support, and the support they get was mostly from information exchange among patients, and they had insufficient cognition of surgical knowledge, improvement degree and risk, and low participation in clinical decision making.Conclusion:Patients with postpartum abdominal wall laxity in China have an urgent psychological need for abdominoplasty, but there are many factors that have adverse effects on their decision-making experience.

Purpose:
Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict adverse survival outcomes among patients with colorectal cancer (CRC). This study evaluates the prognostic value of NLR among patients with obstructing CRC who successfully underwent stenting before curative surgery.
Methods:
We retrospectively reviewed patients who underwent stenting before surgery. Patient demographics, tumor characteristics, perioperative outcomes, recurrence-free survival (RFS), and overall survival (OS) were analyzed. NLR was calculated from the differential white blood cell counts at least 4 days after successful stenting, before elective surgery. Optimal cutoff to dichotomize NLR was obtained by maximizing log-rank test statistic with recursive partitioning of KaplanMeier RFS and OS curves. The optimal cutoff for high NLR was ≥ 5 at presentation before stenting, and ≥ 4 after stenting.
Results:
Fifty-seven patients with localized obstructing CRC underwent successful endoscopic stenting before curative surgery. High NLR was associated with lymphovascular invasion (P = 0.006) and apical lymph node involvement (P = 0.034). Major perioperative complication(s) (hazard ratio [HR], 11.34; 95% confidence interval [CI], 2.49 to 51.56; P < 0.01) and high NLR (HR, 3.69; 95% CI, 1.46 to 9.35; P < 0.01) negatively impacted OS on univariate and multivariate analyses. High NLR negatively impacted RFS on univariate analysis (HR, 2.91; 95% CI, 1.29 to 6.60; P = 0.01).
Conclusion
NLR of ≥ 4 after stenting is an independent prognostic factor among patients with obstructing localized CRC who are successfully decompressed by endoscopic stenting before curative surgery.

Introduction: A cross-sectional study is used to evaluate the lifestyle factors associated with
cardiovascular disease (CVD) risk among healthcare workers in tertiary hospitals in Sarawak, Malaysia.
Methods: A questionnaire-based survey using the Simple Lifestyle Indicator Questionnaire (SLIQ) was
administered to, and anthropometric measurements were collected from, 494 healthcare workers.
Results: Te mean age of the subjects was 32.4±8.4, with a range of 19 to 59 years. Te subjects were
from the allied health (45.5%), management and professional (25.1%) and executive (29.4%) felds.
Overall, 47.4% of the subjects were of normal weight, 30.2% were overweight, 17.2% were obese and
5.2% were underweight. Te mean number of working hours per week for the subjects was 47.6±14.0
with the highest working hours found among the management and professional group, followed by
the executive and allied health groups. Overall, 39.7% of the healthcare workers worked ofce hours,
36.6% worked within the shift system, 20.9% worked ofce hours and were on-call and the remaining
2.8% worked a mixture of ofce hours and shifts. Based on the SLIQ score, 58.1% were classifed as
at intermediate risk for CVD, 38.5% were in the healthy category and 3.4% were in the unhealthy
category. Factors associated with a healthier lifestyle were being female (Odds Ratio [OR]= 12.1; CI=
3.2- 46.4), professional (mean score= 6.70), in the allied health group (mean score=7.33) and in the
normal BMI group (OR= 9.3, CI= 1.8- 47.0).
Conclusion: In our study, healthcare workers had an intermediate risk of developing CVD in the
future. Tus, there is a need to intervene in the lifestyle factors contributing to CVD.

OBJECTIVE:To provide reference for clinical empirical treatme nt of non-fermentative Gram-negative bacilli (NFGNB)infection. METHODS :All kinds of clinical specimens were collected from Jan. 2010 to Dec. 2019 in a tertiary hospital from Hanzhong city of Shaanxi province ;the distribution and drug resistance of NFGNB were analyzed retrospectively. RESULTS : A total of 26 386 strains of pathogenic bacteria were detected in the hospital during 2010-2019,including 4 077 strains of NFGNB (15.45%),mainly from patients ≥60 years old (1 836 strains,45.05%). During the 10 years,the detection rate of NFGNB decreased from 20.14% in 2010 to 15.36% in 2019 (P<0.001). Acinetobacter baumannii (1 359 strains),Pseudomonas aeruginosa (1 269 strains),Stenotrophomonas maltophilia (447 strains) and Burkholderia cepacia (351 strains) were main pathogens. The detected NFGNB mainly came from hospitalized patients (4 001 strains),and most of them were found in ICU (17.05%),neurosurgery department (14.52%),respiratory department (12.41%),and respiratory tract (66.69%),secretion (7.80%)specimens. The detection rates of A. baumannii and P. aeruginosa in oncology department ,blood specimens and urine specimens showed an overall upward trend ,while the detection rates in ICU of the hospital showed a downward trend (P<0.05); the detection rate of P. aeruginosa in neurosurgery department showed an upward trend (P<0.05),and that of A. baumannii in respiratory department showed an upward trend (P<0.05). The resistance rate of A. baumannii to carbapenems increased from about 10% in 2010 to about 75% in 2019,and the guyh3201@163.com resistance rate to cephalosporins exceeded 78%. The resistance rates of P. aeruginosa to imipenem and me ropenem were lower than 35% and 30% respectively,and the trend of drug resistance did not change significantly (P>0.05);the resistance rates to 12 kinds of clinically commonly used antibiotics as piperacillin and aztreonam were lower than 40%. The resistance rate of S. maltophilia to compound sulfamethoxazole showed a decreasing trend (P<0.001),and the resistance rate to ceftazidime was high (54.70%-74.10%). The resistance rates of B. cepacia to compound sulfamethoxazole,meropenem and ceftazidime showed a downward trend (P<0.01),and were lower than 15% after 2014. CONCLUSIONS:Although the detection rate of NFGNB in our hospital showed a downward trend ,the multi-drug resistance and pan-drug resistance of A. baumannii are serious ,and the resistance rate to carbapenems is increased. Sensitive drugs such as cefoperazone/sulbactam,amikacin,levofloxacin and ceftazidime should be selected for NFGNB infection according to the results of drug sensitivity tests.
