Preoperative evaluation of gastric cancer and risk factors for postoperative complications / 中华胃肠外科杂志

Surgical resection plays pivotal role in the treatment of gastric cancer. Adequate preoperative evaluation, precise intraoperative maneuver and delicate postoperative management lay the foundation for successful gastrectomy. The aim of preoperative evaluation is to stage tumor and identify potential risk factors (including preoperative factors like age, ASA status, body mass index, comorbidity, hypoalbuminemia, and intraoperative factors like blood loss and combined resection) which could lead to postoperative complication. With the management of prehabilitation, adequate medical decision could be made and patient's fast recovery could be ensured. With the rapid adoption of ERAS concept, there is increasing attention to prehabilitation which focus on optimization of cardio-pulmonary capacity and muscular-skeletal capacity. Despite of the efficacy of prehabilitation demonstrated by randomized controlled trials, consensus has yet to be reached on the following items: specific intervention, optimal measurement, candidate population and optimal timing for intervention. Balancing the efficiency and safety, preoperative evaluation could be put into clinical practice smoothly.

Factors influencing super-long hospital stays in patients undergoing radical gastrectomy in the age of enhanced recovery after surgery / 中华胃肠外科杂志

Objective: To obtain experience and generate suggestions for reducing average hospital stays, optimizing perioperative management of patients with gastric cancer and improving utilization of medical resources by analyzing the factors influencing super-long hospital stays in patients undergoing radical gastrectomy in the age of enhanced recovery after surgery (ERAS). Methods: This was a case-control study. Inclusion criteria: (1) pathologically diagnosed gastric adenocarcinoma; (2) radical surgery for gastric cancer; and (3) complete clinicopathologic data. Exclusion criteria: (1) history of upper abdominal surgery; (2) presence of distant metastasis of gastric cancer or other ongoing neoplastic diseases; (3) concurrent chemoradiotherapy; and (4) preoperative gastric cancer-related complications such as obstruction or perforation. The study cohort comprised 285 eligible patients with hospital stays of ≥30 days (super-long hospital stay group). Using propensity score matching in a 1:1 ratio, age, sex, medical insurance, pTNM stage, and extent of surgical resection as matching factors, 285 patients with hospital stays of < 30 days during the same period were selected as the control group (non-long hospital stay group). The primary endpoint was relationship between pre-, intra-, and post-operative characteristics and super-long hospital stays. Clavien-Dindo grade was used to classify complications. Results: Univariate analysis showed that number of comorbidities, number of preoperative consultations, preoperative consultation, inter-departmental transference, operation time, open surgery, blood loss, intensive care unit time, presence of surgical or non-surgical complications, Clavien-Dindo grade of postoperative complications, and reoperation were associated with super-long hospital stays (all P<0.05). Inter-departmental transference (OR=4.876, 95% CI: 1.500-16.731, P<0.001), preoperative consultation time ≥ 3 d (OR=1.758, 95%CI: 1.036-2.733, P=0.034), postoperative surgery-related complications (OR = 6.618, 95%CI: 2.141-20.459, P=0.01), and higher grade of complications (Clavien-Dindo Grade I: OR = 7.176, 95%CI: 1.785-28.884, P<0.001; Clavien-Dindo Grade II: OR = 18.984, 95%CI: 6.286-57.312, P<0.001; Clavien-Dindo Grade III-IV: OR=7.546, 95%CI:1.495-37.952, P=0.014) were independent risk factors for super-long hospital stays. Conclusion: Optimizing preoperative management, enhancing perioperative management, and surgical quality control can reduce the risk of prolonging average hospital stay.

Perception of upper lip augmentation utilizing simulated photography

BACKGROUND: No head to head comparison is available between surgical lip lifting and upper lip filler injections to decide which technique yields the best results in patients. Despite the growing popularity of upper lip augmentation, its effect on societal perceptions of attractiveness, successfulness and overall health in woman is unknown. METHODS: Blinded casual observers viewed three versions of independent images of 15 unique patient lower faces for a total of 45 images. Observers rated the attractiveness, perceived success, and perceived overall health for each patient image. Facial perception questions were answered on a visual analog scale from 0 to 100, where higher scores corresponded to more positive responses. RESULTS: Two hundred and seventeen random observers with an average age of 47 years (standard deviation, 15.9) rated the images. The majority of observers were females (n=183, 84%) of white race (n=174, 80%) and had at least some college education (n=202, 93%). The marginal mean score for perceived attractiveness from the natural condition was 1.5 points (95% confidence interval [CI], 0.9–2.18) higher than perceived attractiveness from the simulated upper lip filler injection condition, and 2.6 points higher (95% CI, 1.95–3.24) than the simulated upper lip lift condition. There was a moderate to strong correlation between the scores of the same observer. CONCLUSIONS: Simulated upper lip augmentation is amenable to social perception analysis. Scores of the same observer for attractiveness, successfulness, and overall health are strongly correlated. Overall, the natural condition had the highest scores in all categories, followed by simulated upper lip filler, and lastly simulated upper lip lift.

Prophylactic Dual Catheter Technique to Prevent Side Branch Snowplowing Complications during Angioplasty and Stenting

OBJECTIVE: Angioplasty and Stenting of intracranial atherosclerotic lesions have a higher complication rate and a large proportion of this is attributable to side branch arterial occlusion from forceful displacement of the atheroma into the ostia or snowplowing effect. This can result in severe disabilities when it result in small infarcts involving eloquent areas in the posterior circulation or the motor tracts. MATERIALS AND METHODS: We present a series of 6 cases utilizing a new dual catheter technique for maintaining the patency of at-risk vessels during angioplasty and stenting. There are several methods previously described to help reduce the incidence of stroke but because they do not have a physical presence in the ostia to protect it, they are unable to guarantee the patency of the vessel. RESULTS: All 6 patients underwent angioplasty and stenting with the technique. The patients were assessed for complications with post-procedure magnetic resonance imaging and no complications were found. CONCLUSION: In this preliminary series, the dual catheter technique appears to safe and effective in preventing occlusion of the adjacent branch arteries. This technique may facilitate the use of the Wingspan stent in the treatment of intracranial atherosclerotic stenotic segments by reducing the risk of peri-procedural stroke.

Post community hospital discharge rehabilitation attendance: Self-perceived barriers and participation over time

<p><b>INTRODUCTION</b>This study aimed to examine the attendance rates of post-discharge supervised rehabilitation as recommended by the multidisciplinary team at discharge among subacutely disabled adults and the barriers preventing adherence.</p><p><b>MATERIALS AND METHODS</b>Patients were from a community hospital, aged 40 years or older. They had been assessed by a multidisciplinary team to benefit from rehabilitation after discharge, were mentally competent and communicative. We used a sequential qualitative-quantitative mixed methods study design. In the initial qualitative phase, we studied the patient-perceived barriers to adherence to rehabilitation using semi-structured interviews. Emerging themes were then analysed and used to develop a questionnaire to measure the extent of these barriers. In the subsequent quantitative phase, the questionnaire was used with telephone follow-up at 3, 6, 9 and 12 months after discharge.</p><p><b>RESULTS</b>Qualitative phase interviews (n = 41) revealed specific perceived financial, social, physical and health barriers. At the start of the quantitative phase (n = 70), 87.1% of the patients viewed rehabilitation as beneficial, but overall longitudinal attendance rate fell from 100% as inpatient to 20.3% at 3 months, 9.8% at 6 months, 6.3% at 9 months and 4.3% at 12 months. The prevalence of physical and social barriers were high initially but decreased with time. In contrast, the prevalence of financial and perceptual barriers increased with time.</p><p><b>CONCLUSION</b>Attendance of post-hospitalisation rehabilitation in Singapore is low. Self-perceived barriers to post-discharge rehabilitation attendance were functional, social, financial and perceptual, and their prevalence varied with time.</p>

Retarding progression of myopia with seasonal modification of topical atropine

To investigate whether seasonal modification in the concentration of atropine drops is effective in retarding the progression of myopia. Two hundred and forty eyes of 120 healthy preschool-and school-age children in Chiayi region, Taiwan were recruited. The treatment group consisted of 126 eyes of 63 children who received atropine eye drops daily for one year and the control group included 114 eyes of 57 children who received nothing. The concentration of atropine eye drops was modified by seasonal variation as follows: 0.1% for summer, 0.25% for spring and fall, and 0.5% for winter. Refractive error, visual acuity, intraocular pressure [IOP], and axial length were evaluated before and after intervention. Mean age was 9.1 +/- 2.8 years in the atropine group versus 9.3 +/- 2.8 years in controls [p= 0.88]. Mean spherical equivalent, refractive error and stigmatism were -1.90 +/- 1.66 diopters [D] and -0.50 +/- 0.59 D in the atropine group; corresponding values in the control group were -2.09 +/- 1.67 D [P= 0.97] and -0.55 +/- 0.60 D [P = 0.85], respectively. After one year, mean progression of myopia was 0.28 +/- 0.75 D in the atropine group vs. 1.23 +/- 0.44 D in controls [P < 0.001]. Myopic progression was significantly correlated with an increase in axial length in both atropine [r = 0.297, P = 0.001] and control [r = 0.348, P < 0.001] groups. No correlation was observed between myopic progression and IOP in either study group. Modifying the concentration of atropine drops based on seasonal variation, seems to be effective and tolerable for retarding myopic progression in preschool- to school-age children
