Hypoglycemia After Ingestion of "Street Valium" Containing Glyburide, Alcohol, and Cocaine.

Background/Objective: Because of their similar appearance and inexpensive cost, sulfonylureas can cause hypoglycemia when substituted for benzodiazepines by the illicit drug market. We present a patient who developed hypoglycemia after ingestion of what she thought to be Valium; work-up revealed sulfonylurea exposure. Case Report: A 33-year-old patient was brought to the hospital after being found unresponsive by paramedics with a reported venous blood glucose level of 18 mg/dL (reference range, 70-140 mg/dL). This prompted treatment with 12.5 g of dextrose administered intravenously. At the hospital, the venous blood glucose level was 15 mg/dL resulting in intravenous dextrose infusion initiation. Once stable, the patient endorsed a medical history of substance use disorder and anxiety. She reported ingesting 2 blue pills given to her by a friend as Valium for her anxiety. Laboratory values showed an elevated insulin level of 47.4 mIU/mL (2.6-24.9), an elevated C-peptide level of 5.4 ng/mL (1.1-4.4), and a glucose level of 44 mg/dL (>70 mg/dL). The patient underwent a 72-hour fasting test. Blood hypoglycemia agent screening showed positive results for glyburide (>5 ng/mL). The patient was discharged home in stable condition. Discussion: There are approximately 2 to 5 case reports of hypoglycemia among persons taking illicit drugs containing sulfonylureas. Laboratory values consistent with the use of a hypoglycemic agent include elevated insulin and C-peptide levels, a low glucose level, and positive results for hypoglycemia agent screening. Conclusion: Sulfonylurea-induced hypoglycemia may lead to clinical sedation, mimicking the effects of benzodiazepines. Sulfonylurea substitution or drug contamination should be suspected when severe hypoglycemia is diagnosed in unresponsive patients suspected of taking illicit drugs.

Dexamethasone, Glycemic Control, and Outcomes in Patients With Type 2 Diabetes Mellitus Undergoing Elective, Primary Total Joint Arthroplasty.

Background: Dexamethasone (DEX) has been shown to reduce pain and postoperative nausea and vomiting for patients undergoing elective total joint arthroplasty (TJA). We investigated the impact of DEX on glycemic control and outcomes in patients with type 2 diabetes mellitus undergoing elective primary TJA. Methods: All patients with type 2 diabetes mellitus undergoing primary elective TJA between January 2016 and December 2021 at 4 sites within 1 hospital system were identified. Propensity scores were calculated to match patients receiving or not receiving DEX. Primary outcomes were perioperative blood glucose levels and the incidence of hyperglycemia. Secondary outcomes were the amount of insulin administered, the occurrence of 30-day postoperative surgical site infections, hospital readmission, and mortality. Results: After matching, we identified 1372 patients. DEX administration was associated with a significant increase in mean blood glucose levels in mg/dL on postoperative days (PODs) 0 to 2: POD 0 (28.4, 95% confidence interval [CI]: 24.6-32.1), POD 1 (14.4, 95% CI: 10.1-18.8), POD 2 (12.4, 95% CI: 7.5-17.2) when comparing patients who did or did not receive DEX. Additionally, patients receiving DEX, compared to patients who did not receive DEX, had increased odds of experiencing hyperglycemia on POD 0 (odds ratio: 4.0, 95% CI: 3.1-5.2). DEX was not associated with a significant difference in insulin administration, surgical site infections, hospital readmission, or mortality. Conclusions: In our review of 1372 patients with propensity-matched type 2 diabetes mellitus undergoing elective, primary TJA, we found that DEX administration was associated with an increased risk of elevated mean glucose on POD 0-2, hyperglycemia on POD 0, but was not associated with an increase in total insulin dose administered nor occurrence of surgical site infections, hospital readmission, or mortality within 30 days of surgery in patients who received DEX compared to patients who did not receive DEX. Level of Evidence: IV.

Sex and APOE genotype influence respiratory function under hypoxic and hypoxic-hypercapnic conditions.

The apolipoprotein E (APOE) gene has been studied due to its influence on Alzheimer's disease (AD) development and work in an APOE mouse model recently demonstrated impaired respiratory motor plasticity following spinal cord injury (SCI). Individuals with AD often copresent with obstructive sleep apnea (OSA) characterized by cessations in breathing during sleep. Despite the prominence of APOE genotype and sex as factors in AD progression, little is known about the impact of these variables on respiratory control. Ventilation is tightly regulated across many systems, with respiratory rhythm formation occurring in the brainstem but modulated in response to chemoreception. Alterations within these modulatory systems may result in disruptions of appropriate respiratory control and ultimately, disease. Using mice expressing two different humanized APOE alleles, we characterized how sex and the presence of APOE3 or APOE4 influences ventilation during baseline breathing (normoxia) and during respiratory challenges. We show that sex and APOE genotype influence breathing during hypoxic challenge, which may have clinical implications in the context of AD and OSA. In addition, female mice, while responding robustly to hypoxia, were unable to recover to baseline respiratory levels, emphasizing sex differences in disordered breathing.NEW & NOTEWORTHY This study is the first to use whole body plethysmography (WBP) to measure the impact of APOE alleles on breathing under normoxia and during adverse respiratory challenges in a targeted replacement Alzheimer's model. Both sex and genotype were shown to affect breathing under normoxia, hypoxic challenge, and hypoxic-hypercapnic challenge. This work has important implications regarding the impact of genetics on respiratory control as well as applications pertaining to conditions of disordered breathing including sleep apnea and neurotrauma.

Iron-Catalyzed C-H Oxygenation Using Perchlorate Enabled by Secondary Sphere Hydrogen Bonds.

Perchlorate (ClO4-) is a groundwater pollutant that is challenging to remediate. We report a strategy to use Fe(II) tris(2-pyridylmethyl)amine (TPA) complexes featuring appended aniline hydrogen bonds (H-bonds) to promote ClO4- reduction. These complexes facilitate oxygen atom transfer from ClO4- to PPh3 and C-H oxygenation reactions of organic substrates. Catalytic reactions using 15 mol % afforded excellent yields for oxygenation of anthracene and cyclic alkyl aromatics, and this methodology tolerates aryl halides as well as heterocycles containing either O, S, or N.

Safety and efficacy of dynamic catheter-directed cerebral digital subtraction angiography for diagnosis of bowhunter syndrome spectrum disorders: A systematic review of the literature.

INTRODUCTION: Dynamic catheter-directed cerebral digital subtraction angiography (dcDSA) is the gold standard for diagnosing dynamic vascular occlusion syndromes such as bowhunter syndrome (BHS). Nonetheless, concerns about its safety exist and no standardized protocols have been published to date. METHODS: We describe our methodology and insights regarding the use of dcDSA in patients with BHS. We also perform a systematic literature review to identify cases of typical and atypical presentations of BHS wherein dcDSA was utilized and report on any procedural complications related to dcDSA. RESULTS: Our study included 104 cases wherein dcDSA was used for the diagnosis of BHS. There were 0 reported complications of dcDSA. DcDSA successfully established diagnosis in 102 of these cases. Thirty-eight cases were deemed atypical presentations of BHS. Fourteen patients endorsed symptoms during neck flexion/extension. In eight cases, there was dynamic occlusion of bilateral vertebral arteries during a single maneuver. Three patients had multiple areas of occlusion along a single vertebral artery (VA). An anomalous entry of the VA above the C6 transverse foramen was observed in four patients. One patient had VA occlusion with neutral head position and recanalization upon contralateral lateral head tilt. CONCLUSION: Our study highlights the safety and diagnostic benefits of dcDSA in characterizing the broad spectrum of BHS pathology encountered in clinical practice. This technique offers a powerful means to evaluate changes in cerebral blood flow and cervical arterial morphology in real time, overcoming the constraints of static imaging methods. Our findings pave the way for further studies on dcDSA to enhance cross-sectional imaging methods for the characterization of BHS and other dynamic vascular occlusion syndromes.

Neonatal and maternal outcomes at early vs. full term following induction of labor; A secondary analysis of the OBLIGE randomized trial.

INTRODUCTION: Birth at early term (37+0-38+6 completed gestational weeks [GW] and additional days) is associated with adverse neonatal outcomes compared with waiting to ≥39 GW. Most studies report outcomes after elective cesarean section or a mix of all modes of births; it is unclear whether these adverse outcomes apply to early-term babies born after induction of labor (IOL). We aimed to determine, in women with a non-urgent induction indication (elective/planned >48 h in advance), if IOL at early and late term was associated with adverse neonatal and maternal outcomes compared with IOL at full term. MATERIAL AND METHODS: An observational cohort study as a secondary analysis of a multicenter randomized controlled trial of 1087 New Zealand women with a planned IOL ≥37+0 GW. Multivariable logistic regression was used to analyze neonatal and maternal outcomes in relation to gestational age; 37+0-38+6 (early term), 39+0-40+6 (full term) and ≥41+0 (late term) GW. Neonatal outcome analyses were adjusted for sex, birthweight, mode of birth and induction indication, and maternal outcome analyses for parity, age, body mass index and induction method. The primary neonatal outcome was admission to neonatal intensive care unit (NICU) for >4 hours; the primary maternal outcome was cesarean section. RESULTS: Among the 1087 participants, 266 had IOL at early term, 480 at full term, and 341 at late term. Babies born following IOL at early term had increased odds for NICU admission for >4 hours (adjusted odds ratio [aOR] 2.16, 95% confidence intervals (CI) 1.16-4.05), compared with full term. Women having IOL at early term had no difference in emergency cesarean rates but had an increased need for a second induction method (aOR 1.70, 95% CI 1.15-2.51) and spent 4 h longer from start of IOL to birth (Hodges-Lehmann estimator 4.10, 95% CI 1.33-6.95) compared with those with IOL at full term. CONCLUSIONS: IOL for a non-urgent indication at early term was associated with adverse neonatal and maternal outcomes and no benefits compared with IOL at full term. These findings support international guidelines to avoid IOL before 39 GW unless there is an evidence-based indication for earlier planned birth and will help inform women and clinicians in their decision-making about timing of IOL.

'Now I Have Dreams in Place of the Nightmares': An Updated Systematic Review of Post-Traumatic Growth Among Refugee Populations.

Trauma exposure places refugees at serious risk of developing mental health difficulties. However, research also recognizes that refugees can respond to trauma with psychological development and growth, commonly referred to as post-traumatic growth (PTG). An updated systematic review was conducted to investigate PTG across different refugee populations, including the processes that mediate this phenomenon, and the use of therapy in promoting PTG. A systematic search of CINAHL Complete, Proquest 5000, PsychINFO, Scopus, and Web of Science was performed to identify studies exploring PTG in refugee populations, published between June 2013 and November 2021. In all, 26 studies met the inclusion criteria for this review. Quantitative results reveal a positive correlation between PTG and religious commitment and coping, and the effectiveness of narrative and community-based interventions in facilitating PTG. Qualitative results facilitate insight into the complex ways refugees find meaning and strength after trauma through religion, comparison-based thinking, helping others, and storytelling. Findings highlight the need for future research and interventions to recognize the distinct PTG experiences of different refugee populations.

Targeting the Microbiome to Improve Gut Health and Breathing Function After Spinal Cord Injury.

Spinal cord injury (SCI) is a devastating condition characterized by impaired motor and sensory function, as well as internal organ pathology and dysfunction. This internal organ dysfunction, particularly gastrointestinal (GI) complications, and neurogenic bowel, can reduce the quality of life of individuals with an SCI and potentially hinder their recovery. The gut microbiome impacts various central nervous system functions and has been linked to a number of health and disease states. An imbalance of the gut microbiome, i.e., gut dysbiosis, contributes to neurological disease and may influence recovery and repair processes after SCI. Here we examine the impact of high cervical SCI on the gut microbiome and find that transient gut dysbiosis with persistent gut pathology develops after SCI. Importantly, probiotic treatment improves gut health and respiratory motor function measured through whole-body plethysmography. Concurrent with these improvements was a systemic decrease in the cytokine tumor necrosis factor-alpha and an increase in neurite sprouting and regenerative potential of neurons. Collectively, these data reveal the gut microbiome as an important therapeutic target to improve visceral organ health and respiratory motor recovery after SCI. Research Highlights: Cervical spinal cord injury (SCI) causes transient gut dysbiosis and persistent gastrointestinal (GI) pathology.Treatment with probiotics after SCI leads to a healthier GI tract and improved respiratory motor recovery.Probiotic treatment decreases systemic tumor necrosis factor-alpha and increases the potential for sprouting and regeneration of neurons after SCI.The gut microbiome is a valid target to improve motor function and secondary visceral health after SCI.

Paleopathology and osteobiography of the people of Peñuelas, Chile's semiarid north

The Museo de La Serena, IV Region, Chile has collections of skeletal remains representing the agricultural Diaguita people of 500 years ago excavated in the 1980s from the sites Peñuelas 21 and 24, Chile's semiarid north. Their excellent preservation has permitted an osteobiographical and radiographic analysis to better understand the patterns of the disease. This research continues the osteological analyses begun in 1989 by Rosado that seek to understand the impact the transition to and adoption of farming had on the health of prehistoric populations. Because of the significance of paleopathology in the understanding of cultural and biological adaptations, it has also become necessary to assess the preservation status and design a conservation protocol to protect and document the remains. The objectives of this communication are to: establish demographic patterns of the skeletal samples and identify and diagnose skeletal paleopathologies via photography and radiographs. Intentional cranial alteration, limb and cranial fractures, dental wear, and dental abscesses and caries are among the interesting paleopathologies so far documented. Intentional cranial alteration is very common and is manifested as tabular erect in both males and females. The high frequency of carious lesions indicates a diet that emphasized carbohydrates. Skeletal radiographs are available for several of the individuals in the sample and this has afforded a more detailed description of the paleopathologies originally documented via photography.
