Ecuador’s National Surgical Strengthening Plan: first in Latin America, provides hope for surgical care agenda

Since 2015, there has been a notable increase in global efforts by various stakeholders to promote and advance surgical care policies, as proposed by the Lancet Commission on Global Surgery (LCoGS) namely, the development of the National Surgical Obstetric Anesthesia Planning (NSOAP), a country- driven framework that offers a comprehensive approach to health ministries to enhance their surgical systems. Ecuador has affirmed its position as a leading advocate for surgical care in Latin America. Following a two-year process, Ecuador is the first country in the Region of the Americas to launch an NSSP as a key component of a robust health system, including improving emergency responsiveness and pre- paredness

Innovative blood transfusion strategies to address global blood deserts: a consensus statement from the Blood Delivery via Emerging Strategies for Emergency Remote Transfusion (Blood DESERT) Coalition.

In rural settings worldwide, many people live in effective blood deserts without access to any blood transfusion. The traditional system of blood banking is logistically complex and expensive for many resource-restricted settings and demands innovative and multidisciplinary solutions. 17 international experts in medicine, industry, and policy participated in an exploratory process with a 2-day hybrid seminar centred on three promising innovative strategies for blood transfusions in blood deserts: civilian walking blood banks, intraoperative autotransfusion, and drone-based blood delivery. Participant working groups conducted literature reviews and interviews to develop three white papers focused on the current state and knowledge gaps of each innovation. Seminar discussion focused on defining blood deserts and developing innovation-specific implementation agendas with key research and policy priorities for future work. Moving forward, advocates should prioritise the identification of blood deserts and address the context-specific challenges for these innovations to alleviate the ongoing crisis in blood deserts.

Foxa2 and Pet1 Direct and Indirect Synergy Drive Serotonergic Neuronal Differentiation.

Neuronal programming by forced expression of transcription factors (TFs) holds promise for clinical applications of regenerative medicine. However, the mechanisms by which TFs coordinate their activities on the genome and control distinct neuronal fates remain obscure. Using direct neuronal programming of embryonic stem cells, we dissected the contribution of a series of TFs to specific neuronal regulatory programs. We deconstructed the Ascl1-Lmx1b-Foxa2-Pet1 TF combination that has been shown to generate serotonergic neurons and found that stepwise addition of TFs to Ascl1 canalizes the neuronal fate into a diffuse monoaminergic fate. The addition of pioneer factor Foxa2 represses Phox2b to induce serotonergic fate, similar to in vivo regulatory networks. Foxa2 and Pet1 appear to act synergistically to upregulate serotonergic fate. Foxa2 and Pet1 co-bind to a small fraction of genomic regions but mostly bind to different regulatory sites. In contrast to the combinatorial binding activities of other programming TFs, Pet1 does not strictly follow the Foxa2 pioneer. These findings highlight the challenges in formulating generalizable rules for describing the behavior of TF combinations that program distinct neuronal subtypes.

Centralization of pancreatic cancer treatment within an integrated healthcare system improves overall survival.

BACKGROUND: Higher-volume centers for pancreatic cancer surgeries have been shown to have improved outcomes such as length of stay. We examined how centralization of pancreatic cancer care within a regional integrated healthcare system improves overall survival. METHODS: We conducted a retrospective study of 1621 patients treated for pancreatic cancer from February 2010 to December 2018. Care was consolidated into 4 Centers of Excellence (COE) in surgery, medical oncology, and other specialties. Descriptive statistics, bivariate analysis, Chi-square tests, and Kaplan-Meier analysis were performed. RESULTS: Neoadjuvant chemotherapy use rose from 10% to 31% (p < .001). The median overall survival (OS) improved by 3 months after centralization (p < .001), but this did not reach significance on multivariate analysis. CONCLUSIONS: Our results suggest that in a large integrated healthcare system, centralization improves overall survival and neoadjuvant therapy utilization for pancreatic cancer patients.

Clinical Characteristics Predict the Yield of Head Computed Tomography Scans among Intoxicated Trauma Patients: Implications for the Initial Work-up.

BACKGROUND AND AIMS: Alcohol intoxication may confound the clinical assessment of the trauma patient. Head computed tomography (h-CT) is the standard imaging technique to rule out intracranial injury in most intoxicated trauma patients. The objective of this study was to determine whether certain clinical findings (computed clinical score [CCS]) could predict the h-CT yield, admission, and neurosurgical consultation (NSC) among intoxicated trauma patients. MATERIALS AND METHODS: This is a 4-year retrospective cohort study (2013-2017) of trauma patients who presented to our level 1 trauma center emergency department with alcohol intoxication. For each patient, a computed clinical score (CCS) was generated based on the following findings: age ≥50 years, Glasgow Coma Scale <13, evidence of trauma above the clavicles, amnesia, loss of consciousness, headache, vomiting, and seizures. The primary endpoints were NSC, admission, and acute h-CT finding. Univariate and multivariate regressions were used to compare predictors of the primary endpoints. RESULTS: We identified 437 intoxicated trauma patients (median age: 35 years [interquartile range: 25-50]; 71.9% men; median blood alcohol content: 207.8 mg/dL). One hundred and twenty-four (30.4%) patients had acute findings on h-CT, 351 (80.3%) were admitted, and 112 (25.6%) received NSC. On multivariate analysis, CCS was the only predictor of acute h-CT (odds ratio [OR] =1.6; 95% confidence interval [CI]: 1.3-2.0; P < 0.0001) and the best predictor of admission (OR = 1.6; 95% CI: 1.3-1.9; P < 0.0001) and NSC (OR = 1.8; 95% CI: 1.5-2.3; P < 0.0001). CONCLUSIONS: One-third of intoxicated trauma patients have acute findings on h-CT. While the CCS was the best predictor of acute h-CT findings, hospital admission, and NSC, h-CT scanning should continue to be a standard of care.

Double-barreled Wet Colostomy Versus Separate Urinary and Fecal Diversion in Patients Undergoing Total Pelvic Exenteration: A Cohort Meta-analysis.

BACKGROUND: The aim of this meta-analysis was to determine whether double-barreled wet colostomy (DBWC) provides similar urinary tract infection rates as separate urinary and fecal diversion (SUFD) in patients undergoing pelvic exenteration. METHODS: The MEDLINE, PubMed, Cochrane Library, and Scopus databases were systematically searched by two independent researchers. The primary endpoint was the urinary tract infection rate. The Mantel-Haenszel method with odds ratios with 95% confidence intervals (OR (95%CI)) was used as an effect measure for dichotomous variables. A random-effects model was used for the meta-analysis. Statistical heterogeneity among effect estimates was evaluated using I2 and Tau2. RESULTS: Three observational studies that included a total of 257 patients (159 DBWC; 98 SUFD) were included after 14 potentially eligible records were screened. Pooled urinary tract infection rates were 1.9% (3/159) in DBWC and 6.1% (6/98) in SUFD. This difference was not statistically significant [OR (95%CI) = 0.27 (0.06, 1.19); p=0.08] with low among-study heterogeneity (I2=0%). CONCLUSIONS: This meta-analysis did not find a significant difference in urinary tract infection rates between DBWC and SUFD in patients undergoing total pelvic exenteration. Further clinical studies will be required to further understand the pros and cons of these procedures.
