Timely follow‐up of positive cancer screening results: A systematic review and recommendations from the PROSPR Consortium

Timely follow‐up for positive cancer screening results remains suboptimal, and the evidence base to inform decisions on optimizing the timeliness of diagnostic testing is unclear. This systematic review evaluated published studies regarding time to follow‐up after a positive screening for breast, cervical, colorectal, and lung cancers. The quality of available evidence was very low or low across cancers, with potential attenuated or reversed associations from confounding by indication in most studies. Overall, evidence suggested that the risk for poorer cancer outcomes rises with longer wait times that vary within and across cancer types, which supports performing diagnostic testing as soon as feasible after the positive result, but evidence for specific time targets is limited. Within these limitations, we provide our opinion on cancer‐specific recommendations for times to follow‐up and how existing guidelines relate to the current evidence. Thresholds set should consider patient worry, potential for loss to follow‐up with prolonged wait times, and available resources. Research is needed to better guide the timeliness of diagnostic follow‐up, including considerations for patient preferences and existing barriers, while addressing methodological weaknesses. Research is also needed to identify effective interventions for reducing wait times for diagnostic testing, particularly in underserved or low‐resource settings.

Pattern recognition using transabdominal ultrasound to diagnose ovarian mature cystic teratoma

Objective

To determine the validity of sonographic pattern recognition in the diagnosis of mature cystic teratoma.

Methods

Consecutive patients scheduled for elective surgery for adnexal masses were included in the study. All patients underwent transabdominal ultrasound with color extended-flow mapping within 24 hours prior to surgery. Examinations were performed by the same sonographer to identify benign cystic teratoma. The final diagnoses were based on histopathologic findings.

Results

A total of 329 consecutive patients were recruited; 23 were excluded because the masses were not adnexal masses. Of the remaining 306 patients, 36 masses were found to be mature cystic teratomas and 270 were nonteratomas. Sonographic pattern recognition showed a sensitivity of 94.4% and a specificity of 98.2%.

Conclusion

Sonographic pattern recognition using transabdominal ultrasound with color extended-flow mapping can accurately diagnose mature cystic teratoma.     

Temporal effect of Guanxin No. 2 on cardiac function, blood viscosity and angiogenesis in rats after long-term occlusion of the left anterior descending coronary artery

AIM: Cardiac infarction is one of the main causes of death in both developing and developed countries over past decades. Currently available approaches for treating patients with this disease are not satisfactory. Traditional Chinese medicines have been increasingly paid attention to. The aim of this study was to characterize the dynamic protective effects of Guanxin No. 2 decoction (GX II) on cardiac dysfunction combined with the blood viscosity and myocardial hypertrophy parameters in myocardial infarction (MI) rats. METHODS: Male Sprague-Dawley rats (180-200 g) were randomly divided into three groups: sham-operated, coronary artery ligation (CAL), and CAL plus GX II (GX II, 10.0 g raw materials/kg/d, bid, p.o.). The experiment was carried out at 4 time points as the 3rd, 7th, 14th, and 28th day after ligation. RESULT: It was found that on the one hand, GX II could significantly improve the heart function, and remarkably decrease infarct size and inhibit ventricular remodeling. On the other hand, GX II showed some unique effects such as angiogenesis which was induced in the left ventricular tissue. This result was consistent with the finding of an augmented vascular endothelial growth factor (VEGF) expression in this area. CONCLUSIONS: The studies demonstrated that GX II exerted extensively beneficial cardioprotective effect on CAL rats, it might stimulate angiogenesis of ischemic region to compensate blood supply to the heart via upregulated VEGF expression.     

Prepregnancy body mass index and adverse pregnancy outcomes

OBJECTIVE: The aim of this study was to evaluate the association between prepregnancy BMI, and adverse maternal and neonatal outcomes. METHOD: In this retrospective cohort study 916 consecutive singleton gestations were included who gave birth between 1 January 2006 and 31 August 2006 at the Department of Obstetrics and Gynecology, University of Udine, Italy. Statistical analysis was performed using univaried logistic regression and measured by odds ratio. RESULTS: The obese patients had a statistically, significantly increased incidence of Caesarean section (OR = 2.17, p = 0.009). Women with overweight (OR = 2.43, p = 0.002) and obese weight (OR = 4.86, p < 0.0001) were at increased risk for preterm deliveries. The pre-eclampsia and the fetal macrosomia (> or =4,000 g) were increased in obese women (OR = 5.68, p < 0.0001; OR = 2.58, p = 0.033, respectively). CONCLUSION: Maternal prepregnancy obesity is significantly associated with increased risk of Caesarean section, preterm delivery, pre-eclampsia and macrosomia.     

探究三维超声成像诊断乳腺肿块的临床应用价值

目的：探究与分析三维超声成像诊断乳腺肿块的临床应用价值。方法方便选取并回顾性分析该院自2013年9月—2015年9月收治的90例乳腺肿块患者的临床资料,该组患者均接受了二维超声、三维超声及弹性成像检查,将上述3种检查结果与术后病理结果进行对照。结果二维超声敏感性为79.03%,特异性为70.83%,准确性为74.63%,三维超声敏感性为89.83%,特异性为78.95%,准确性为84.33%,弹性超声成像敏感性为92.60%,特异性为82.5%,准确性为86.57%,三维超声与弹性超声成像敏感性、特异性及准确性相比均差异无统计学意义(P>0.05)。三维超声与弹性超声成像敏感性、特异性及准确性与二维超声相比均明显增高,差异有统计学意义(P<0.05)。结论三维超声的诊断准确率明显高于二维超声,且与弹性超声成像无明显差异,临床医生可将其应用于乳腺肿块的诊断过程中,为进一步治疗提供合理依据。     

利用大众传播加强医院宣传工作的策略

医院宣传通常采取大众传播和人际传播两种方式。由于大众传播具有广泛性、及时性、高效性和较强的渗透性等特点,得到了医院管理者的普遍重视。而＂走出去＂＂迎进来＂和＂自造新闻＂三种宣传策略,将有助于医院利用大众传播扩大知名度、打造特色品牌。     

The Relationship between Fat Mass Percentage and Glucose Metabolism in Children and Adolescents: A Systematic Review and Meta-Analysis

To assess the relationship between fat mass percentage (FMP) and glucose metabolism in children aged 0–18 years we performed a systematic review of the literature on Medline/PubMed, SinoMed, Embase and Cochrane Library using the PRISMA 2020 guidelines up to 12 October 2021 for observational studies that assessed the relationship of FMP and glucose metabolism. Twenty studies with 18,576 individuals were included in the meta-analysis. The results showed that FMP was significantly associated with fasting plasma glucose (FPG) (r = 0.08, 95% confidence interval (CI): 0.04–0.13, p < 0.001), fasting plasma insulin (INS) (r = 0.48, 95% CI: 0.37–0.57, p < 0.001), and homeostasis model assessment (HOMA)- insulin resistance (IR) (r = 0.44, 95% CI: 0.33–0.53, p < 0.001). The subgroup analysis according to country or overweight and obesity indicated that these associations remained significant between FMP and INS or HOMA-IR. Our results demonstrated that there is a positive relationship between FMP and FPG. Moreover, subgroup analysis according to country or overweight and obesity indicated that FMP is significantly associated with INS and HOMA-IR. This is the first known systematic review and meta-analysis to determine the associations of FMP with glucose metabolism in children and adolescents.
