RESUMEN

BACKGROUND: We aimed to assess risk factors for neonatal mortality, quality of neonatal resuscitation (NR) on videos and identify potential areas for improvement. METHODS: This prospective cohort study included women in childbirth and their newborns at four district hospitals in Pemba, Tanzania. Videos were analysed for quality-of-care. Questionnaires on quality-of-care indicators were answered by health workers (HW) and women. Risk factors for neonatal mortality were analysed in a binomial logistic regression model. RESULTS: 1440 newborns were enrolled. 34 newborns died within the neonatal period (23.6 per 1000 live births). Ninety neonatal resuscitations were performed, 20 cases on video. Positive pressure ventilation (PPV) was inadequate in 15 cases (75%). Half (10/20) did not have PPV initiated within the first minute, and in one case (5.0%), no PPV was performed. PPV was not sustained in 16/20 (80%) newborns. Of the 20 videos analysed, death occurred in 10 newborns: 8 after resuscitation attempts and two within the first 24 h. Most of HW 49/56 (87.5%) had received training in NR. CONCLUSIONS: Video analysis of NR revealed significant deviations from guidelines despite 87.5% of HW being trained in NR. Videos provided direct evidence of gaps in the quality of care and areas for future education, particularly effective PPV. IMPACT: Neonatal mortality in Pemba is 23.6 per 1000 livebirths, with more than 90% occurring in the first 24 h of life. Video assessment of neonatal resuscitation revealed deviations from guidelines and can add to understanding challenges and aid intervention design. The present study using video assessment of neonatal resuscitation is the first one performed at secondary-level hospitals where many of the world's births are conducted. Almost 90% of the health workers had received training in neonatal resuscitation, and the paper can aid intervention design by understanding the actual challenges in neonatal resuscitation.

RESUMEN

Enhanced Recovery After Surgery (ERAS) is the integration of multiple perioperative evidence-based medical practices into a single pathway aimed at eliminating surgical liabilities and improving treatment accuracy to enhance patients' postoperative outcomes. The ERAS Society has been developing guidelines that are widely applicable in the surgical field. ERAS pathways in selective and noncomplicated cases are extensively practiced. However, the ERAS literature excludes patients with comorbidities, such as gastric cancer complicated with diabetes mellitus (DM). Current ERAS guidelines exclude patients with DM in enhanced recovery programs because of insufficient evidence-based medicine on the molecular physiology of the patients in response to surgical insult. Therefore, it is important to implement accelerated rehabilitation surgery for patients with gastric cancer and DM. This review discusses the feasibility and necessity of applying ERAS guidelines to patients with gastric cancer complicated by DM. In addition, we documented the need to lay a logical foundation for enhanced recovery after surgery in patients with gastric cancer complicated by DM.

RESUMEN

OBJECTIVES: To assess the feasibility of using video recordings of neonatal resuscitation (NR) to evaluate the quality of care in a low-resource district hospital. DESIGN: Prospective observational feasibility study. SETTING: Chake-Chake Hospital, a district hospital in Pemba, Tanzania, in April and May 2019. PARTICIPANTS: All delivering women and their newborns were eligible for participation. MAIN OUTCOME MEASURES: Motion-triggered cameras were mounted on resuscitation tables and provided recordings that were analysed for quality of care indicators based on the national NR algorithm. Assessment of feasibility was conducted using Bowen's 8-point framework for feasibility studies. RESULTS: 91% (126 of 139) of women and 96% (24 of 26) of health workers were comfortable or very comfortable with the video recordings. Of 139 newborns, 8 underwent resuscitation with bag and mask ventilation. In resuscitations, heat loss prevention measures were not performed in half of the cases (four of eight), clearing the airway was not performed correctly in five of eight cases, and all newborns were suctioned vigorously and repeatedly, even when not indicated. In a quarter (two of eight) of cases, the newborn's head was not positioned correctly. Additionally, two of the eight newborns needing ventilation were not ventilated within the first minute of life. In none of the eight cases did ventilation appear to be performed effectively. CONCLUSIONS: It proved feasible to use video recordings to assess quality of care during NR in a low-resource setting, and the method was considered acceptable for the delivering women and health workers. Recordings of eight resuscitations all demonstrated deviations from NR guidelines.

RESUMEN

BACKGROUND: The highest neonatal mortality is in Sub-Saharan Africa, where neonatal sepsis accounts for approximately 50%. At Pemba Island, Tanzania, we examined the use of prophylactic antibiotics in neonates and related it to WHO guidelines and compared clinical signs of infection with the use of antibiotic treatment; furthermore, we aimed to investigate all use of antibiotic treatment in the neonatal period. METHOD: This prospective observational cohort study was performed from 1 January 2022 to 15 April 2022 at a district hospital on Pemba Island, Tanzania. Women admitted in early established or active labour, and their neonates, were eligible for inclusion. We used questionnaires for mother and health worker and examined the neonates 2 h after birth. Follow-up was made at discharge or at 18 h of life, and days 7 and 28. RESULTS: We included 209 women and their 214 neonates. The neonatal mortality was 5 of 214 (23 per 1000 live births). According to WHO guidelines 29 (13.6%) had ≥ 1 risk factor for infection. Of these, three (10.3%) received prophylactic antibiotic treatment; only one (3.4%) received the correct antibiotic drug recommended in guidelines. Thirty-nine (18.2%) neonates had ≥ 1 clinical indicator of infection and 19 (48.7%) of these received antibiotic treatment. A total of 30 (14.0%) neonates received antibiotics during the study period. Twenty-three (76.7%) were treated with peroral antibiotics. CONCLUSION: Adherence to WHO guidelines for prophylactic antibiotic treatment to prevent neonatal infection was low. Further, only half of neonates with clinical signs of infection received antibiotics.

RESUMEN

BACKGROUND: Gastrointestinal bleeding is the most common clinical manifestation of gastrointestinal stromal tumor. It is of great significance to the prognosis of patients. But the results are controversial. The purpose of this study was to evaluate the relationship between gastrointestinal bleeding and clinical prognosis in patients with GIST. METHODS: A systematic literature search was performed in Pumbed, Cochrane Library, EMBASE, ClinicalTrials.gov, CNKI, VIP and wanfang databases with the pattern of unlimited languages. 12 studies with 2781 individuals were included in the final analysis. The overall survival (OS), recurrence-free survival/disease-free survival (RFS/DFS) and related factors affecting bleeding in patients with gastrointestinal stromal tumor (GIST) were extracted. Hazard ratio (HR) and 95% confidence interval (CI) were used for in the meta-analysis. RESULTS: A total of 12 articles were included in the study, including 2781 patients with GIST, including 845 patients with gastrointestinal bleeding. The OS of GIST patients with gastrointestinal bleeding was significantly worse (HR = 2.54, 95% CI = 1.13-5.73, P = 0.025). But there was no significant difference in RFS between gastrointestinal bleeding patients and non-bleeding patients (HR = 1.35, 95% CI = 0.70-2.61, P = 0.371). Further analysis of the related factors of GI bleeding in GIST patients was observed, besides the aging factor (HR = 1.02, 95% CI = 0.69-1.50, P = 0.929), Small intestinal stromal tumor (HR = 0.56, 95% CI = 0.41-0.76, P < 0.001), tumor diameter ≥ 5 cm (HR = 2.09, 95% CI = 1.20-3.63, P = 0.009), Mitotic index ≥ 5/50 HPF (HR = 1.66, 95% CI = 1.11-2.49, P = 0.014) and tumor rupture (HR = 2.04, 95% CI = 1.0-3.82, P = 0.026) all increased the risk of GI bleeding in patients with GIST. CONCLUSIONS: The OS of GIST patients with GI bleeding was worse than non-GI bleeding, but had no significant effect on RFS. Nevertheless the aging factor, the location of GIST in the small intestine, tumor diameter ≥ 5 cm, Mitotic index ≥ 5/50 HPF and tumor rupture all increased the risk of GI bleeding in patients with GIST.

RESUMEN

BACKGROUND: Low anterior, ultralow anterior, and intersphincteric resection are conventional, elective anus-sparing techniques for low rectal cancer, and good prognosis depends on a good blood supply and tension-free anastomosis. AIM: The goal is to assess the effect of preserving the arc formed by the left colic and proximal inferior mesenteric arteries (IMAs), and first branch of the sigmoid arteries on the anastomotic blood supply, tension, and leakage rate in anus-sparing surgery for low rectal cancer. METHOD: From 2011 to 2020, a patient with low rectal cancer resection was distributed into the ligation group (42 cases with inferior mesenteric artery ligation) and the preservation group (61 cases with preservation of the left colic and proximal IMAs and first branch of the sigmoid artery). RESULTS: We evaluated patient characteristics, operative results, morbidity, and postoperative follow-up results. There were comparable outcomes between ligation and preservation groups in relations to the number of patients in each operative procedure, duration of surgery, operative blood loss, postoperative hospital stay, and the number of patients with protective stoma (P >.05). In postoperative morbidity, there were similar outcomes between ligation and preservation groups in terms of anastomotic subclinical dehiscence, bleeding and stricture, and urinary retention (P >.05). There were significant differences in anastomotic leakage and intra-abdominal abscess (P < .05). CONCLUSION: Preservation of the arterial arc formed by left colic artery, proximal IMA, and the first branch of sigmoid arteries with apical lymph node dissection could increase anastomotic blood supply, reduce anastomotic tension, and leakage rate in anus-saving treatment of low rectal cancer.

RESUMEN

While repurposed drugs came in handy earlier in the wake of the coronavirus disease 2019 (COVID-19) pandemic, vaccination has been considered a more sustainable approach. The recent spikes have been linked to "double," "triple," and even multi-mutant variants, thus renewing calls for deeper structural and functional insights of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as a lead to rationale design of therapeutics, vaccines, and point-of-care diagnostics. There is a repertoire of findings from the earliest SARS-CoV-2 molecular mimicry to evade host immunity cum host immune responses to the role of the viral glycocalyx in modulating the susceptibility and severity of infection through attraction and repulsive interactions. Recently, molecular studies of some viral components that aid infection in the face of vaccination seem unending. In addition, the wave of infections and the attendant case fatality ratios have necessitated the need for emergency use authorizations for COVID-19 vaccines and in vitro diagnostics. This review provides key updates of SARS-CoV-2, current antigenic and formulation strategies, with emergency use authorizations considerations for future vaccine candidates and diagnostics. We also premise that despite the difficulty in modeling and analyzing glycans, understanding and exploiting their roles in the SARS-CoV-2 architecture is fundamental to glycan-based COVID-19 vaccines devoid of inconsistent clinical outcomes.

RESUMEN

BACKGROUND: Additional studies comparing several reconstruction methods after proximal gastrectomy have been published; of note, it is necessary to update systematic reviews and meta-analysis from the current evidence-based literature. AIM: To expand the current knowledge on feasibility and safety, and also to analyze postoperative outcomes of several reconstructive techniques after proximal gastrectomy. METHODS: PubMed, Google Scholar, and Medline databases were searched for original studies, and relevant literature published between the years 1966 and 2019 concerning various reconstructive techniques on proximal gastrectomy were selected. The postoperative outcomes and complications of the reconstructive techniques were assessed. Meta-analyses were performed using Rev-Man 5.0. A total of 29 studies investigating postoperative outcomes of double tract reconstruction, jejunal pouch interposition, jejunal interposition, esophagogastrostomy, and double flap reconstruction were finally selected in the quantitative analysis. RESULT: Pooled incidences of reflux esophagitis for double tract reconstruction, jejunal pouch interposition, jejunal interposition esophagogastrostomy, and double flap reconstruction were 8.6%, 13.8%, 13.8%, 19.3%, and 8.9% respectively. Meta-analysis showed a decreased length of hospital in the JI group as compared to the JPI group (heterogeneity: Chi2 = 1.34, df = 1 (P = 0.25); I2 = 26%, test for overall effect: Z = 2.22 (P = 0.03). There was also a significant difference between JI and EG in length of hospital stay with heterogeneity: Chi2 = 1.40, df = 3 (P = 0.71); I2 = 0%, test for overall effect: Z = 5.04 (P < 0.00001). Operative time was less in the EG group as compared to the JI group (heterogeneity: Chi2 = 31.09, df = 5 (P < 0.00001); I2 = 84%, test for overall effect: Z = 32.35 (P < 0.00001). CONCLUSION: Although current reconstructive techniques present excellent anti-reflux efficacy, the optimal reconstructive method remains to be determined. The double flap reconstruction proved to lower the rate of complication, but the DTR, JI, JPI, and EG groups showed higher incidence of complications in anastomotic leakage, anastomotic stricture, and residual food. In the meta-analysis result, the complications between the JI, JPI, and EG were comparable but the EG group showed to have better postoperative outcomes concerning the operative time, blood loss, and length of hospital stay.

RESUMEN

BACKGROUND: Postsurgical patients' oral feeding begins with clear fluids 1-3 days after surgery. This might not be sufficiently nutritious to boost the host immune system and provide sufficient energy in gastric neoplastic patients to achieve the goal of enhanced recovery after surgery (ERAS). Our objective was to analyze the significance of early postoperative feeding tubes in boosting patients' immunity and decreasing incidence of overall complications and hospital stay in gastric cancer patients' post-gastrectomy. METHODS: From January 2005 to May 24, 2019, PubMed and Cochrane databases were searched for studies involving enteral nutrition (EN) feeding tubes in comparison to parenteral nutrition (PN) in gastric cancer patients undergoing gastrectomy for gastric malignancies. Relative risk (RR), mean difference (MD), or standard mean difference (SMD) with 95% confidence interval (CI) were used to estimate the effect sizes, and heterogeneity was assessed by using Q and χ2 statistic with their corresponding P values. All the analyses were performed with Review Manager 5.3 and SPSS version 22. RESULTS: Nine randomized trials (n = 1437) and 5 retrospective studies (n = 421) comparing EN feeding tubes and PN were deemed eligible for the pooled analyses, with a categorized time frame of PODs ≥ 7 and PODs < 7. Ratio of CD4+/CD8+ in EN feeding tubes was the only outcome of PODs < 7, which showed significance (MD 0.22, 95% CI 0.18-0.25, P < 0.00001). Regarding other immune indicators, significant outcomes in favor of EN feeding tubes were measured on POD ≥ 7: CD3+ (SMD 1.71; 95% CI 0.70, 2.72; P = 0.0009), CD4+ (MD 5.84; 95% CI 4.19, 7.50; P < 0.00001), CD4+/CD8+ (MD 0.28; 95% CI 0.20; 0.36, P < 0.00001), NK cells (SMD 0.94; 95% CI 0.54, 1.30; P < 0.00001), nutrition values, albumin (SMD 0.63; 95% CI 0.34, 0.91; P < 0.001), prealbumin (SMD 1.00; 95% CI 0.52, 1.48; P < 0.00001), and overall complications (risk ratio 0.73 M-H; fixed; 95% CI 0.58, 0.92; P = 0.006). CONCLUSION: EN feeding tube support is an essential intervention to elevate patients' immunity, depress levels of inflammation, and reduce the risk of complications after gastrectomy for gastric cancer. Enteral nutrition improves the innate immune system and nutrition levels but has no marked significance on certain clinical outcomes. Also, EN reduces the duration of hospital stay and cost, significantly.
