Background Difficult laparoscopic cholecystectomy (DLC) denotes the surgical extraction of the gallbladder under circumstances where associated conditions within the same organ, adjacent structures, or patient-specific conditions impede a smooth, expeditious, and comfortable dissection. It is imperative to utilize tools that aid in anticipating this challenging surgical scenario, enabling the implementation of appropriate measures. Objective This study aimed to assess the effectiveness of the Labbad-Vivas score (LVS) in predicting DLC and its correlation with the Parkland Grading Scale (PGS)...

This review discusses the grading of cholecystitis, the optimal timing of cholecystectomy, adopting a culture of safe cholecystectomy, understanding the common error traps that can lead to intraoperative complications and how to avoid them. The Tokyo Guidelines, AAST, Nassar and Parkland scoring systems are discussed. The patient factors, physiologic status and operative findings that predict a difficult cholecystectomy or conversion from laparoscopic to open cholecystectomy are reviewed. With laparoscopic expertise and patient conditions that are not prohibitive, early laparoscopic cholecystectomy is recommended...

BACKGROUND: In a large multicenter trial, The Parkland Grading Scale(PGS) for acute cholecystitis outperformed other grading scales and has a positive correlation with complications but is limited in its inability to preoperatively predict high-grade cholecystitis. We sought to identify preoperative variables predictive of high-grade cholecystitis(PGS 4 or 5). METHODS: In a six-month period, patients undergoing cholecystectomy at a single institution with prospectively graded PGS were analyzed...

After every school shooting in the United States both a wish and a fear arise: Will this be the one? Will this be the tipping point for change in a nation so deeply divided over the meaning of "the right to bear arms?" Sandy Hook, Connecticut? No. Parkland, Florida? No. So, why might the killing of 19 children and 2 teachers in Uvalde, Texas, prove different? The American epidemic of mass school shootings betrays a country's willingness to let its children disappear, to sacrifice them on the altar of an archetypally violent ethos...

BACKGROUND: Although low-dose, CT-based lung cancer screening (LCS) can decrease lung cancer mortality in high-risk individuals, the process may be complex and pose challenges to patients, particularly those from minority underinsured and uninsured populations. We conducted a randomized controlled trial of telephone-based navigation for LCS within an integrated, urban, safety-net health care system. PATIENTS AND METHODS: Patients eligible for LCS were randomized (1:1) to usual care with or without navigation at Parkland Health in Dallas, Texas...

OBJECTIVE: UCS survival outcome disparities by race have been reported. We aimed to investigate social determinants of health (SDOH) and their relation to survival outcomes in women at two affiliated high-volume institutions serving a racially and economically diverse population. METHODS: Women diagnosed with stage I-IV UCS treated at St. Paul University Hospital, University of Texas Southwestern (UTSW) Zale Lipshy Pavilion-William P. Clements Jr. University Hospital, and Parkland Memorial Hospital between 1992 and 2022 were eligible...

BACKGROUND: No available scale, at the time of initial evaluation for necrotizing enterocolitis (NEC), accurately predicts, i.e., with an area under the curve (AUC) ≥ ≥ 0.9, which preterm infants will undergo surgery for NEC stage III or die within a week. METHODS: This is a retrospective cohort study (n=261) of preterm infants <33 weeks' gestation or <1500 grams birthweight with either suspected or with definite NEC born at Parkland Hospital between 2009-2021...

IMPORTANCE: Melanoma in Black individuals has an annual incidence of approximately 1 in 100 000 people. Most studies of melanoma in Black patients have used population databases, which lack important, precise clinical details. OBJECTIVE: To identify patient-level and tumor-level characteristics of melanoma in Black patients. DESIGN, SETTING, AND PARTICIPANTS: This case series included Black patients with melanoma at 2 tertiary care centers (University of Texas Southwestern [UTSW] Medical Center and Parkland Health), affiliated with a single institution, UTSW in Dallas, Texas...

Despite the importance of agroforestry parkland systems for ecosystem and livelihood benefits, evidence on determinants of carbon storage in parklands remains scarce. Here, we assessed the direct and indirect influence of human management (selective harvesting of trees), abiotic factors (climate, topography, and soil) and multiple attributes of species diversity (taxonomic, functional, and structural) on aboveground carbon (AGC) stocks in 51 parklands in drylands of Benin. We used linear mixed-effects regressions and structural equation modeling to test the relative effects of these predictors on AGC stocks...

INTRODUCTION: The correlation between mass shootings, firearm injuries, and mental health is an ongoing polarized debate within the U.S., making it essential to develop public policy on mental illness and firearm injuries exacerbated by a significant increase in firearm sales in March 2020. Although many mass shooters are labeled "mentally ill," mental illness is only present in a small minority of cases. Most mentally ill people are never violent but are more likely to be the victims of violence...

BACKGROUND: Patients with large burns must be carefully resuscitated to balance adequate tissue perfusion with the risk of end-organ damage. One devastating complication of overresuscitation is abdominal compartment syndrome. Reducing the volume of fluids given during resuscitation may reduce the incidence of abdominal compartment syndrome and improve outcomes. OBJECTIVE: To determine whether decreasing fluid resuscitation volume in a burn center reduced the incidence of abdominal compartment syndrome...

The Minnesota Bee Atlas project contributed new information about bee distributions, phenologies, and community structure by mobilizing participatory science volunteers to document bees statewide. Volunteers submitted iNaturalist (©2016 California Academy of Sciences) photograph observations, monitored nest-traps for tunnel-nesting bees, and conducted roadside observational bumble bee surveys. By pairing research scientists and participatory science volunteers, we overcame geographic and temporal challenges to document the presence, phenologies, and abundances of species...

The effects of temperature and relative humidity (RH) on female reproductive output, egg development and larval survival were determined for Rocky Mountain wood ticks (Dermacentor andersoni) from a prairie population (Chin Lakes, Alberta, Canada) near the northern distribution limit of this species. The responses of D. andersoni eggs and unfed larvae to different temperature (25 or 32 °C) and RH (35, 55, 75, 85 or 95%) regimes were compared to our previously published data (Diyes et al. 2021) for a northern prairie population of American dog ticks (Dermacentor variabilis)...

AUDIENCE: This scenario was developed to educate emergency medicine residents on the diagnosis and management of patients with an inhalational airway injury secondary to a house fire. BACKGROUND: Burn injuries are a common occurrence encountered by the emergency physician. According to the National Hospital Ambulatory Medical Care Survey, around 371,000 patients were treated in emergency departments for fire or burn injuries across the United States in 2020. This represents around 1% of emergency department visits related to injury, poisoning, or adverse effects...

AIMS AND BACKGROUND: As the use of minimally invasive or microinvasive glaucoma surgery (MIGS) continues to expand, it is important to look at its outcomes in the hands of trainees. This study aims to examine the efficacy and safety of Kahook Dual Blade (KDB) goniotomy and endocyclophotocoagulation (ECP) with cataract extraction (CE) done by residents and fellows. METHODS: All cases of KDB or ECP performed with CE between 2012 and 2020 at Parkland were reviewed, excluding cases with multiple MIGS procedures or other procedures...

BACKGROUND: Most studies examining the effects of neighbourhood urban design on cardiometabolic health focused solely on the built or natural environment. Also, they did not consider the roles of neighbourhood socio-economic status (SES) and ambient air pollution in the observed associations, and the extent to which these associations were mediated by physical activity and sedentary behaviours. METHODS: We used data from the AusDiab3 study (N = 4141), a national cohort study of Australian adults to address the above-mentioned knowledge gaps...

BACKGROUND: This paper presents a comparative inventory of medicinal plant taxa and their uses by smallholder farming communities of four cultures in the Aswa River catchment of northern Uganda, situated in the eastern Sudanian savanna parkland ecotype of sub-Saharan Africa. The purpose of the study was to document the ethnobotanical use of medicinal plants by the Lango, Acholi, Teso (Atesot) and Ethur (jo Abwor), in an historical moment before civil conflict and mass displacement of the respondent communities disrupted the inter-generational transmission of traditional technical knowledge within the study area...

INTRODUCTION: CAC can be detected on routine chest computed tomography (CT) scans and may contribute to CVD risk estimation, but the accuracy of visual CAC scoring may be affected by the specialty of the interpreting radiologist and/or the use of contrast. METHODS: The accuracy of visual CAC estimation on non-gated CT scans was evaluated at UT Southwestern Medical Center (UTSW) and Parkland Health and Hospital System (PHHS). All adults who underwent CAC scanning and a non-gated CT scan within 6 months were identified and the scores from the two CTs were compared overall and stratified by type of reader and whether contrast was used...

BACKGROUND: Though artificial intelligence ("AI") has been increasingly applied to patient care, many of these predictive models are retrospective and not readily available for real-time decision-making. This survey-based study aims to evaluate implementation of a new, validated mortality risk calculator (Parkland Trauma Index of Mortality, "PTIM") embedded in our electronic healthrecord ("EHR") that calculates hourly predictions of mortality with high sensitivity and specificity. METHODS: This is a prospective, survey-based study performed at a level 1 trauma center...

OBJECTIVES: The extent and timing of surgery in severely injured patients remains an unsolved problem in orthopaedic trauma. Different laboratory values or scores have been used to try to predict mortality and estimate physiological reserve. The Parkland Trauma Index of Mortality (PTIM) has been validated as an electronic medical record-integrated algorithm to help with operative timing in trauma patients. The aim of this study was to report our initial experience with PTIM and how it relates to other scores...
