Three-year survival and distribution of lymph node metastases in gastric cancer following neoadjuvant chemotherapy: results from a European randomized clinical trial.

BACKGROUND: Adequate lymphadenectomy is an important step in gastrectomy for cancer, with a modified D2 lymphadenectomy being recommended for advanced gastric cancers. When assessing a novel technique for the treatment of gastric cancer, lymphadenectomy should be non-inferior. The aim of this study was to assess completeness of lymphadenectomy and distribution patterns between open total gastrectomy (OTG) and minimally invasive total gastrectomy (MITG) in the era of peri-operative chemotherapy. METHODS: This is a retrospective analysis of the STOMACH trial, a randomized clinical trial in thirteen hospitals in Europe. Patients were randomized between OTG and MITG for advanced gastric cancer after neoadjuvant chemotherapy. Three-year survival, number of resected lymph nodes, completeness of lymphadenectomy, and distribution patterns were examined. RESULTS: A total of 96 patients were included in this trial and randomized between OTG (49 patients) and MITG (47 patients). No difference in 3-year survival was observed, this was 57.1% in OTG group versus 46.8% in MITG group (P = 0.186). The mean number of examined lymph nodes per patient was 44.3 ± 16.7 in the OTG group and 40.7 ± 16.3 in the MITG group (P = 0.209). D2 lymphadenectomy of 71.4% in the OTG group and 74.5% in the MITG group was performed according to the surgeons; according to the pathologist compliance to D2 lymphadenectomy was 30% in the OTG group and 36% in the MITG group. Tier 2 lymph node metastases (stations 7-12) were observed in 19.6% in the OTG group versus 43.5% in the MITG group (P = 0.024). CONCLUSION: No difference in 3-year survival was observed between open and minimally invasive gastrectomy. No differences were observed for lymph node yield and type of lymphadenectomy. Adherence to D2 lymphadenectomy reported by the pathologist was markedly low.

The effect of a Mentor Mothers program on prevention of vertical transmission of HIV outcomes in Zambézia Province, Mozambique: a retrospective interrupted time series analysis.

INTRODUCTION: Mentor Mothers (MM) provide peer support to pregnant and postpartum women living with HIV (PPWH) and their infants with perinatal HIV exposure (IPE) throughout the cascade of prevention of vertical transmission (PVT) services. MM were implemented in Zambézia Province, Mozambique starting in August 2017. This evaluation aimed to determine the effect of MM on PVT outcomes. METHODS: A retrospective interrupted time series analysis was done using routinely collected aggregate data from 85 public health facilities providing HIV services in nine districts of Zambézia. All PPWH (and their IPE) who initiated antiretroviral therapy (ART) from August 2016 through April 2019 were included. Outcomes included the proportion per month per district of: PPWH retained in care 12 months after ART initiation, PPWH with viral suppression and IPE with HIV DNA PCR test positivity by 9 months of age. The effect of MM on outcomes was assessed using logistic regression. RESULTS: The odds of 12-month retention increased 1.5% per month in the pre-MM period, compared to a monthly increase of 7.6% with-MM (35-61% pre-MM, 56-72% with-MM; p < 0.001). The odds of being virally suppressed decreased by 0.9% per month in the pre-MM period, compared to a monthly increase of 3.9% with-MM (49-85% pre-MM, 59-80% with-MM; p < 0.001). The odds of DNA PCR positivity by 9 months of age decreased 8.9% per month in the pre-MM period, compared to a monthly decrease of 0.4% with-MM (0-14% pre-MM, 4-10% with-MM; p < 0.001). The odds of DNA PCR uptake (the proportion of IPE who received DNA PCR testing) by 9 months of age were significantly higher in the with-MM period compared to the pre-MM period (48-100% pre-MM, 87-100% with-MM; p < 0.001). CONCLUSIONS: MM services were associated with improved retention in PVT services and higher viral suppression rates among PPWH. While there was ongoing but diminishing improvement in DNA PCR positivity rates among IPE following MM implementation, this might be explained by increased uptake of HIV testing among high-risk IPE who were previously not getting tested. Additional efforts are needed to further optimize PVT outcomes, and MM should be one part of a comprehensive strategy to address this critical need.

CD4 Trends with evolving treatment initiation policies among children living with HIV in zambézia province, mozambique, 2012-2018

Background: Historically, antiretroviral therapy (ART) initiation was based on CD4 criteria, but this has been replaced with "Test and Start" wherein all people living with HIV are offered ART. We describe the baseline immunologic status among children relative to evolving ART policies in Mozambique. Methods: This retrospective evaluation was performed using routinely collected data. Children living with HIV (CL aged 5-14 years) with CD4 data in the period of 2012-2018 were included. ART initiation "policy periods" corresponded to implementation of evolving guidelines: in period 1 (2012-2016), ART was recommended for CD4 <350 cells/mm3; during period 2 (2016-2017), the CD4 threshold increased to <500 cells/mm3; Test and Start was implemented in period 3 (2017-2018). We described temporal trends in the proportion of children with severe immunodeficiency (CD4 <200 cells/mm3) at enrollment and at ART initiation. Multivariable regression models were used to estimate associations with severe immunodeficiency. Results: The cohort included 1815 children with CD4 data at enrollment and 1922 at ART initiation. The proportion of children with severe immunodeficiency decreased over time: 20% at enrollment into care in period 1 vs. 16% in period 3 (P = 0.113) and 21% at ART initiation in period 1 vs. 15% in period 3 (P = 0.004). Children initiating ART in period 3 had lower odds of severe immunodeficiency at ART initiation compared with those in period 1 [adjusted odds ratio (aOR) = 0.67; 95% CI: 0.51 to 0.88]. Older age was associated with severe immunodeficiency at enrollment (aOR = 1.13; 95% CI: 1.06 to 1.20) and at ART initiation (aOR = 1.14; 95% CI: 1.08 to 1.21). Conclusions: The proportion of children with severe immunodeficiency at ART initiation decreased alongside more inclusive ART initiation guidelines. Earlier treatment of children living with HIV is imperative.

Health related quality of life following open versus minimally invasive total gastrectomy for cancer: Results from a randomized clinical trial.

INTRODUCTION: Minimally invasive techniques show improved short-term and comparable long-term outcomes compared to open techniques in the treatment of gastric cancer and improved survival has been seen with the implementation of multimodality treatment. Therefore, focus of research has shifted towards optimizing treatment regimens and improving quality of life. MATERIALS AND METHODS: A randomized trial was performed in thirteen hospitals in Europe. Patients were randomized between open total gastrectomy (OTG) or minimally invasive total gastrectomy (MITG) after neoadjuvant chemotherapy. This study investigated patient reported outcome measures (PROMs) on health-related quality of life (HRQoL) following OTG or MITG, using the Euro-Qol-5D (EQ-5D) and the European Organization for Research and Treatment of Cancer (EORTC) questionnaires, modules C30 and STO22. Due to multiple testing a p-value < 0.001 was deemed statistically significant. RESULTS: Between January 2015 and June 2018, 96 patients were included in this trial. Forty-nine patients were randomized to OTG and 47 to MITG. A response compliance of 80% was achieved for all PROMs. The EQ5D overall health score one year after surgery was 85 (60-90) in the open group and 68 (50-83.8) in the minimally invasive group (P = 0.049). The median EORTC-QLQ-C30 overall health score one year postoperatively was 83,3 (66,7-83,3) in the open group and 58,3 (35,4-66,7) in the minimally invasive group (P = 0.002). This was not statistically significant. CONCLUSION: No differences were observed between open total gastrectomy and minimally invasive total gastrectomy regarding HRQoL data, collected using the EQ-5D, EORTC QLQ-C30 and EORTC-QLQ-STO22 questionnaires.

Open versus minimally invasive total gastrectomy after neoadjuvant chemotherapy: results of a European randomized trial.

BACKGROUND: Surgical resection with adequate lymphadenectomy is regarded the only curative option for gastric cancer. Regarding minimally invasive techniques, mainly Asian studies showed comparable oncological and short-term postoperative outcomes. The incidence of gastric cancer is lower in the Western population and patients often present with more advanced stages of disease. Therefore, the reproducibility of these Asian results in the Western population remains to be investigated. METHODS: A randomized trial was performed in thirteen hospitals in Europe. Patients with an indication for total gastrectomy who received neoadjuvant chemotherapy were eligible for inclusion and randomized between open total gastrectomy (OTG) or minimally invasive total gastrectomy (MITG). Primary outcome was oncological safety, measured as the number of resected lymph nodes and radicality. Secondary outcomes were postoperative complications, recovery and 1-year survival. RESULTS: Between January 2015 and June 2018, 96 patients were included in this trial. Forty-nine patients were randomized to OTG and 47 to MITG. The mean number of resected lymph nodes was 43.4 ± 17.3 in OTG and 41.7 ± 16.1 in MITG (p = 0.612). Forty-eight patients in the OTG group had a R0 resection and 44 patients in the MITG group (p = 0.617). One-year survival was 90.4% in OTG and 85.5% in MITG (p = 0.701). No significant differences were found regarding postoperative complications and recovery. CONCLUSION: These findings provide evidence that MITG after neoadjuvant therapy is not inferior regarding oncological quality of resection in comparison to OTG in Western patients with resectable gastric cancer. In addition, no differences in postoperative complications and recovery were seen.

A grounded theory study of the perceptions and meanings associated with gastrostomies among parents of children with palliative needs.

BACKGROUND: There is few literature on the difficulties and different meanings of gastrostomy tubes (GST) for parents of children with palliative needs, and what specific palliative care teams contribute to this process. AIM: To explore the process of information in the decision of performing a gastrostomy and the meanings that parents of children with palliative needs build around them. DESIGN: Semi-structured interviews which were transcribed and analysed using Grounded Theory. SETTING/PARTICIPANTS: Parents and caretakers of children admitted in Paediatric Palliative Care Unit of Madrid Autonomous Community (Spain) whose children bore a gastrostomy device. RESULTS: Two core categories arise ('Fight' and 'The child as a life-meaning generator'). In all the cases, the child supplied the meaning to go on, and the Palliative Care Unit (CPU) helped in the daily care of the child and solving problems derived from the handling of the GT. CONCLUSIONS: It is necessary to improve the process of giving bad news and to introduce models of health care that focus on parents and child as the center of palliative care. It is also necessary to develop educational programs that enable continuity of care at home for children with palliative needs.

Evaluation of participatory teaching methods in undergraduate medical students' learning along the first academic courses.

The European Higher Education Area (EHEA) is an opportunity to redesign medical education. Academic training is now focused on acquiring not only knowledge, but also those competencies critical to face complex professional scenarios. Together with re-evaluating traditional teaching methods, EHEA has forced a technological shift in the way we teach. By critically assessing the impact of novel teaching methodologies, we can better define biomedical education demands. Here, we address this question on a sample of medical students instructed in basic subjects along the first two academic courses. Two hundred and one medical students participated in the study (n = 128 first year, n = 73 second year). Quantitative (conventional survey statistics) and qualitative (open coding) approaches were combined to analyze data from surveys, confidential questionnaires, semi-structured interviews and open discussion. First year medical students rated more positively the use of participatory methodologies than second year students. A major drawback is detected in the perceived workload. Active teaching methodologies show a strong reliance on their time of implementation for medical students, a key aspect to be considered in the design of integrative participatory curricula along the first academic courses.

Hemoperitoneo espontáneo relacionado con desgarro de bridas omentales durante la gestación / Spontaneous hemoperitoneum related to tearing of omental flanges

El hemoperitoneo espontáneo idiopático relacionado con intervenciones quirúrgicas previas y durante la gestación es una situación excepcional pudiendo ser letal para madre y feto. A pesar de los avances médicos, la mortalidad por bajo nivel de sospecha sigue manteniéndose alta. Presentamos el caso de una mujer de 36 años en la semana 30 de gestación, sin antecedentes patológicos o traumáticos salvo cesárea previa tres años antes, que acude con inestabilidad hemodinámica y dolor abdominal severo. Se realiza laparotomía de urgencia evidenciando abundante hemoperitoneo sin punto de sangrado excepto un coágulo centinela en epiplón mayor y superficie anterior uterina (AU)

The spontaneous idiopathic hemoperitoneum related to prior surgical procedures and during pregnancy it’s an exceptional situation, lethal to both mother and fetus. Despite medical advances, mortality due to low level of suspicious remains high. We report the case of a 36 year-old woman at 30 weeks gestation with no history of disease or trauma except a previous cesarean three years ago, who presents with hypovolemia signs and severe abdominal pain. Is performed an emergency laparotomy showing hemoperitoneum without bleeding point except a sentinel clot in the omentum and the anterior surface of the uterus (AU)

[Role of laparoscopic surgery in the treatment of achalasia: an analysis of 50 cases]. / Papel del tratamiento quirúrgico por vía laparoscópica de la achalasia de cardias: análisis de 50 casos.

UNLABELLED: Achalasia is an uncommon oesophageal motor disorder, with a controversial therapeutic management. AIM: The aim of our study was to analyse our experience in the management of achalasia, assessing the impact of minimally invasive surgery, its complications and its outcomes in the short and medium term. METHODS: A retrospective and descriptive study was designed, including all patients operated on between 1999 and 2010 with the diagnosis of achalasia. Previous diagnostic tests, duration of symptoms, previous non-surgical treatment, surgical approach, associated antireflux intervention, surgical time and perioperative complications were analysed. RESULTS: A total of 50 patients, 24 males and 26 females, with a mean age of 47 years underwent laparoscopic surgery. The mean duration of the disease was 2 years. Eleven (22%) patients had received endoscopic treatment (1-4 sessions) prior to the surgery, with 100% of symptomatic recurrence. The surgery was accompanied by a Dor fundoplication in 48 patients, and Toupet fundoplication in the remaining two. The mean surgical time was 123 minutes. There were 9 intraoperative complications (5 gastric mucosal perforations, 2 bleeding, 1 liver injury and 1 aspiration); 4 postoperative complications (3 scapular pain and 1 sub-phrenic collection) were reported. The long-term subjective symptomatic response was excellent/good in 84% of patients, intermediate in 12% and a poor response in 4%. The mean follow-up was 28 months. CONCLUSIONS: Heller cardiomyotomy should be the treatment of choice in selected Achalasia patients, because of its short and long term outcomes, and its low morbidity.
