Menstrual pain in Australian adolescent girls and its impact on regular activities: a population-based cohort analysis based on Longitudinal Study of Australian Children survey data.

OBJECTIVES: To determine the proportion of Australian adolescent girls who experience menstrual pain (dysmenorrhea); to assess associations of dysmenorrhea and period pain severity with adolescents missing regular activities because of their periods. STUDY DESIGN: Prospective, population-based cohort study; analysis of Longitudinal Study of Australian Children (LSAC) survey data. SETTING, PARTICIPANTS: Female adolescents in the nationally representative cross-sequential sample of Australian children recruited in 2004 for the Kinder cohort (aged 4-5 years at enrolment). Survey data from waves 6 (mean age 14 years), wave 7 (16 years) and wave 8 (18 years) were analysed. MAIN OUTCOME MEASURES: Severity of period pain during the preceding three months (very, quite, a little, or not at all painful); number of activity types missed because of periods; relationship between missing activities and period pain severity. RESULTS: Of the 1835 participating female members of the LSAC Kinder cohort at waves 6 to 8, 1600 (87%) responded to questions about menstruation during at least one of waves 6 to 8 of data collection. At wave 6 (14 years), 227 of 644 respondents (35%) reported dysmenorrhea, 675 of 1341 (50%) at wave 6 (16 years), and 518 of 1115 (46%) at wave 8 (18 years). Of the 366 participants who reported period pain severity at all three waves, 137 reported no dysmenorrhea at all three waves (37%), 66 reported dysmenorrhea at all three waves (18%), 89 reported increasing period pain over time (24%), and 38 reported declining pain (10%). At wave 6, 223 of 647 participants reported missing at least one activity because of their periods (34%), 454 of 1341 at wave 7 (34%), and 344 of 1111 at wave 8 (31%). Of the participants who experienced very painful periods, 72% (wave 6), 63% (wave 7), and 65% (wave 8) missed at least one activity type because of their periods, as did 45% (wave 6), 36% (wave 7), and 40% (wave 8) of those who experienced quite painful periods. CONCLUSIONS: A large proportion of adolescent girls in Australia experience period pain that affects their engagement in regular activities, including school attendance. Recognising adolescent period pain is important not only for enhancing their immediate quality of life with appropriate support and interventions, but also as part of early screening for chronic health conditions such as endometriosis.

The Ethical Defensibility of Harm Reduction and Eating Disorders.

Eating disorders are mental illnesses that can have a significant and persistent physical impact, especially for those who are not treated early in their disease trajectory. Although many persons with eating disorders may make a full recovery, some may not; this is especially the case when it comes to persons with severe and enduring anorexia nervosa (SEAN), namely, those who have had anorexia for between 6 and 12 years or more. Given that persons with SEAN are less likely to make a full recovery, a different treatment philosophy might be ethically warranted. One potential yet scarcely considered way to treat persons with SEAN is that of a harm reduction approach. A harm reduction philosophy is deemed widely defensible in certain contexts (e.g. in the substance use and addictions domain), and in this paper we argue that it may be similarly ethically defensible for treating persons with SEAN in some circumstances.

An exploratory mixed-methods crossover study comparing DVD- vs. Web-based patient decision support in three conditions: The importance of patient perspectives.

BACKGROUND: The last 15 years have witnessed considerable progress in the development of decision support interventions (DESIs). However, fundamental questions about design and format of delivery remain. METHODS: An exploratory, randomized mixed-method crossover study was conducted to compare a DVD- and Web-based DESI. Randomized participants used either the Web or the DVD first, followed by the alternative format. Participants completed a questionnaire to assess decision-specific knowledge at baseline and a questionnaire and structured qualitative interview after viewing each format. Tracking software was used to capture Web utilization. Transcripts were analyzed using integrated inductive and deductive approaches. Quantitative data were analyzed using exploratory bivariate and multivariate analyses. RESULTS: Exploratory knowledge analyses suggest that both formats increased knowledge, with limited evidence that the DVD increased knowledge more than the Web. Format preference varied across participants: 44% preferred the Web, 32% preferred the DVD and 24% preferred 'both'. Patient discussions of preferences for DESI information structure and the importance of a patients' stage of a given decision suggest these characteristics may be important factors underlying variation in utilization, format preferences and knowledge outcomes. CONCLUSIONS: Our results suggest that both DESI formats effectively increase knowledge. Patients' perceptions of these two formats further suggest that there may be no single 'best' format for all patients. These results have important implications for understanding why different DESI formats might be preferable to and more effective for different patients. Further research is needed to explore the relationship between these factors and DESI utilization outcomes across diverse patient populations.

Parental decision regret after pediatric urologic surgeries compared to decisions of everyday life.

INTRODUCTION: Parents are at risk of decision regret (DR) for decisions affecting their children. The Decision Regret Scale (DRS) measures medical DR but lacks context outside of healthcare. OBJECTIVE: To compare parental DR 1) between common pediatric urologic surgeries and everyday decisions and 2) with preference to make a different choice. METHODS: We conducted a cross-sectional online survey of randomly selected parents >1year (y) after their children underwent: orchiopexy (males ≤10y), open ureteral reimplant (OUR, females 2-6y), open pyeloplasty (OP, ≤2y), or robotic pyeloplasty (RP, 5-17y) (2017-2021). Higher DRS scores indicate increased DR (none: 0, mild: 1-25, moderate: 30-50, strong: 55-75, very strong: 80-100). Parents completed DRS on four decisions: their child's surgery, most recent/current romantic relationship, most recent leased/purchased car, and most recent purchased meal. Parents reported if they would make the same choice (yes/no). Nonparametric statistics were used. RESULTS: We surveyed 191 parents (orchiopexy n = 52, OUR n = 50, OP n = 51, RP n = 38). The median parent age was 36y (mothers: 86%). Some DR was reported for all decisions, but with significant differences in DR severity. The lowest median DRS score was seen with surgery (orchiopexy 0 [IQR 0-10], OUR 0 [IQR 0-5], OP 0 [IQR 0-0], RP 0 [IQR 0-0]), with no difference between surgery groups (p = 0.78). This was followed by relationship (0, IQR 0-20), car (15, IQR 0-25), and meal (20, IQR 0-30, p < 0.001). Most parents did not report any DR regarding surgery (orchiopexy 69%, OUR 74%, OP 76%, RP 76%, with no difference between surgery groups p = 0.85, Summary Figure). Comparatively, 59% of parents did not have any regret about their relationship, 37% their car, and 28% their meal (p < 0.001). All surgical DR was mild or moderate. No parent (0%) would have chosen differently for their child's surgery versus 4-12% for non-surgical decisions (p < 0.001). Overall, increasing DR corresponded to increasing desire to have made a different choice (DRS≤10: 0%, DRS 45-50: 32%, DRS 55-60: 66%, DRS≥75: 100%, p < 0.001). CONCLUSION: Parental DR varied between urological surgical and non-surgical decisions. It was lowest after surgery. Some regret was reported after every decision, but the subset of parents with regret was smallest after surgical decisions. Positive DRS scores do not necessarily correspond to parents wishing they made a different choice.

Metabolic Insight into Glioma Heterogeneity: Mapping Whole Exome Sequencing to In Vivo Imaging with Stereotactic Localization and Deep Learning.

Intratumoral heterogeneity (ITH) complicates the diagnosis and treatment of glioma, partly due to the diverse metabolic profiles driven by underlying genomic alterations. While multiparametric imaging enhances the characterization of ITH by capturing both spatial and functional variations, it falls short in directly assessing the metabolic activities that underpin these phenotypic differences. This gap stems from the challenge of integrating easily accessible, colocated pathology and detailed genomic data with metabolic insights. This study presents a multifaceted approach combining stereotactic biopsy with standard clinical open-craniotomy for sample collection, voxel-wise analysis of MR images, regression-based GAM, and whole-exome sequencing. This work aims to demonstrate the potential of machine learning algorithms to predict variations in cellular and molecular tumor characteristics. This retrospective study enrolled ten treatment-naïve patients with radiologically confirmed glioma. Each patient underwent a multiparametric MR scan (T1W, T1W-CE, T2W, T2W-FLAIR, DWI) prior to surgery. During standard craniotomy, at least 1 stereotactic biopsy was collected from each patient, with screenshots of the sample locations saved for spatial registration to pre-surgical MR data. Whole-exome sequencing was performed on flash-frozen tumor samples, prioritizing the signatures of five glioma-related genes: IDH1, TP53, EGFR, PIK3CA, and NF1. Regression was implemented with a GAM using a univariate shape function for each predictor. Standard receiver operating characteristic (ROC) analyses were used to evaluate detection, with AUC (area under curve) calculated for each gene target and MR contrast combination. Mean AUC for five gene targets and 31 MR contrast combinations was 0.75 ± 0.11; individual AUCs were as high as 0.96 for both IDH1 and TP53 with T2W-FLAIR and ADC, and 0.99 for EGFR with T2W and ADC. These results suggest the possibility of predicting exome-wide mutation events from noninvasive, in vivo imaging by combining stereotactic localization of glioma samples and a semi-parametric deep learning method. The genomic alterations identified, particularly in IDH1, TP53, EGFR, PIK3CA, and NF1, are known to play pivotal roles in metabolic pathways driving glioma heterogeneity. Our methodology, therefore, indirectly sheds light on the metabolic landscape of glioma through the lens of these critical genomic markers, suggesting a complex interplay between tumor genomics and metabolism. This approach holds potential for refining targeted therapy by better addressing the genomic heterogeneity of glioma tumors.

US Adults' Perceptions, Beliefs, and Behaviors towards Plant-Rich Dietary Patterns and Practices: International Food Information Council Food and Health Survey Insights, 2012-2022.

Expert groups recommend that populations adopt dietary patterns higher in whole, plant-based foods and lower in red and processed meat as a high-impact climate action. Yet, there is limited understanding of populations' willingness to adopt plant-rich dietary patterns. This study examined United States (US) adults' perceptions, beliefs, and behaviors towards plant-rich dietary patterns and practices over a decade. Fifteen questions from the International Food Information Council's Food and Health Surveys (2012-2022) were analyzed across four sustainability domains (i.e., human health, environmental, social, and economic domains). Most respondents had favorable perceptions of environmentally sustainable food and beverages, but sustainability influenced less than half of consumers' purchase decisions. Plant-rich dietary pattern adherence increased across survey years (12.1% [2019] to 25.8% [2022], p < 0.001). One-quarter (28.1%) of Americans reported reducing their red meat intake over 12 months (2020-2022). Yet, another 15.5% reported greater red meat intake, and 18.8% reported greater plant-based meat alternative (PBMA) intake over 12 months. The percentage of respondents who reported greater red meat and PBMA consumption in the previous 12 months significantly increased across the years surveyed (2020-2022, p < 0.05). IFIC Survey findings highlight growing US consumer awareness of health, environmental, and social sustainability but low adoption of plant-rich dietary patterns and practices. Government leadership and coordinated actions by health professionals, civil society, and businesses are needed to educate and incentivize Americans to adopt plant-rich dietary behaviors, and greater industry transparency is needed to show how food and beverage products support human and planetary health.

Dominant-negative heterozygous mutations in AIRE confer diverse autoimmune phenotypes.

Autoimmune polyendocrine syndrome type 1 (APS-1) is an autosomal recessive disease characterized by severe and childhood onset organ-specific autoimmunity caused by mutations in the autoimmune regulator (AIRE) gene. More recently, dominant-negative mutations within the PHD1, PHD2, and SAND domains have been associated with an incompletely penetrant milder phenotype with later onset familial clustering, often masquerading as organ-specific autoimmunity. Patients with immunodeficiencies or autoimmunity where genetic analyses revealed heterozygous AIRE mutations were included in the study and the dominant-negative effects of the AIRE mutations were functionally assessed in vitro. We here report additional families with phenotypes ranging from immunodeficiency, enteropathy, and vitiligo to asymptomatic carrier status. APS-1-specific autoantibodies can hint to the presence of these pathogenic AIRE variants although their absence does not rule out their presence. Our findings suggest functional studies of heterozygous AIRE variants and close follow-up of identified individuals and their families.

How have media campaigns been used to promote and discourage healthy and unhealthy beverages in the United States? A systematic scoping review to inform future research to reduce sugary beverage health risks.

Sugary beverage consumption is associated with many health risks. This study used a proof-of-concept media campaign typology to examine U.S. beverage campaigns that promoted healthy beverages and encouraged or discouraged sugary beverages. We used a three-step systematic scoping review to identify, organize, analyze, and synthesize evidence. Step 1 used Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines to search four electronic databases and gray literature through 2021. Step 2 categorized relevant media campaigns using a media campaign typology. Step 3 examined campaign evaluation outcomes. We identified 280 campaigns organized into six campaign typology categories. The media landscape was dominated by corporate marketing campaigns for branded sugary beverages (65.8%; n = 184) followed by public awareness (9.6%; n = 27), public policy (8.2%; n = 23), social marketing (7.1%; n = 20), corporate social responsibility (5.7%; n = 16), and countermarketing (3.6%; n = 10) campaigns. Evaluations for 20 unique campaigns implemented over 30 years (1992-2021) across 14 states showed reduced sugary beverage or juice and increased water or low-fat milk sales and intake. Positive short-term cognitive and mid-term retail and behavioral changes were reported. There was limited evidence for long-term policy, social norm, and population health outcomes. Future research is needed to use media campaigns in strategic communications to reduce sugary beverage health risks for Americans.

A systematic scoping review of the literacy literature to develop a digital food and nutrition literacy model for low-income adults to make healthy choices in the online food retail ecosystem to reduce obesity risk.

Adults with lower incomes are disproportionately affected by poverty, food insecurity, obesity, and diet-related non-communicable diseases (NCDs). In 2020-2021 amid the coronavirus disease 2019 (COVID-19) pandemic, the United States Department of Agriculture (USDA) expanded the Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot program to enable eligible participants to purchase groceries online in 47 states. This expansion underscores the need for SNAP adults to have digital literacy skills to make healthy dietary choices online. Currently, a digital literacy model does not exist to help guide USDA nutrition assistance policies and programs, such as SNAP. We conducted a systematic scoping review of the academic and gray literature to identify food, nutrition, health, media, financial, and digital literacy models. The search yielded 40 literacy models and frameworks that we analyzed to develop a Multi-dimensional Digital Food and Nutrition Literacy (MDFNL) model with five literacy levels (i.e., functional, interactive, communicative, critical, and translational) and a cross-cutting digital literacy component. Utilization of the MDFNL model within nutrition assistance policies and programs may improve cognitive, behavioral, food security, and health outcomes and support equity, well-being, digital inclusion, and healthy communities to reduce obesity and NCD risks.

Lessons from implementing the Australian National Action Plan for Endometriosis.

Abstract: Endometriosis is a common yet under-recognised chronic disease with one in nine (more than 830,000) women and those assigned female at birth diagnosed with endometriosis by the age of 44 years in Australia. In 2018, Australia was the first country to develop a roadmap and blueprint to tackle endometriosis in a nationwide, coordinated manner. This blueprint is outlined in the National Action Plan for Endometriosis (NAPE), created from a partnership between government, endometriosis experts and advocacy groups. The NAPE aims to improve patient outcomes in the areas of awareness and education, clinical management and care and research. As researchers and clinicians are working to improve the lives of those with endometriosis, we discuss our experiences since the launch of the plan to highlight areas of consideration by other countries when developing research priorities and clinical plans. Historically, major barriers for those with endometriosis have been twofold; first, obtaining a diagnosis and secondly, effective symptom management post-diagnosis. In recent years, there have been calls to move away from the historically accepted 'gold-standard' surgical diagnosis and single-provider specialist care. As there are currently no reliable biomarkers for endometriosis diagnosis, specialist endometriosis scans and MRI incorporating artificial intelligence offer a novel method of visualisation and promising affordable non-invasive diagnostic tool incorporating well-established technologies. The recognised challenges of ongoing pain and symptom management, a holistic interdisciplinary care approach and access to a chronic disease management plan, could lead to improved patient outcomes while reducing healthcare costs. Lay summary: Endometriosis is a chronic disease where tissue like the lining of the uterus is found in other locations around the body. For the 830,000 people living with endometriosis in Australia, this often results in an immense burden on all aspects of daily life. In 2018, Australia was the first country to introduce a roadmap and blueprint to tackle endometriosis in a nationwide coordinated manner with the National Action Plan for Endometriosis. This plan was created as a partnership between government, endometriosis experts and advocacy groups. There are several other countries who are now considering similar plans to address the burden of endometriosis. As researchers and clinicians are working to improve the lives of those with endometriosis, we share our experiences and discuss areas that should be considered when developing these national plans, including diagnostic pathways without the need for surgery, and building new centres of expertise in Endometriosis and Pelvic Pain.

Pandemic H1N1 influenza infection and vascular thrombosis.

During the summer and fall of 2009, significant thrombotic events were observed in patients infected with the pandemic H1N1 influenza A virus. In a retrospective chart review of 119 individuals admitted to the hospital with H1N1 virus infection, 7 patients (5.9%) were found to have experienced thrombotic vascular events.

A Systematic Scoping Review of Media Campaigns to Develop a Typology to Evaluate Their Collective Impact on Promoting Healthy Hydration Behaviors and Reducing Sugary Beverage Health Risks.

Interventions to discourage sugary beverages and encourage water consumption have produced modest and unsustainable behavioral changes to reduce obesity and noncommunicable disease risks. This systematic scoping review examined media campaigns to develop a typology to support healthy hydration nonalcoholic beverage behaviors. Our three-step methodology included the following: (1) review and summarize expert-recommended healthy beverage guidelines; (2) review six English-language electronic databases guided by PRISMA to describe existing campaign types by issue, goal and underlying theory; and (3) develop a media campaign typology to support policies, systems and environments to encourage healthy hydration behaviors. Results showed no international consensus for healthy beverage guidelines, though we describe expert-recommended healthy beverage guidelines for the United States. Of 909 records identified, we included 24 articles describing distinct media campaigns and nine sources that defined models, schemes or taxonomies. The final media campaign typology included: (1) corporate advertising, marketing or entertainment; (2) corporate social responsibility, public relations/cause marketing; (3) social marketing; (4) public information, awareness, education/ health promotion; (5) media advocacy/countermarketing; and (6) political or public policy. This proof-of-concept media campaign typology can be used to evaluate their collective impact and support for a social change movement to reduce sugary beverage health risks and to encourage healthy hydration behaviors.

Applying a Multi-Dimensional Digital Food and Nutrition Literacy Model to Inform Research and Policies to Enable Adults in the U.S. Supplemental Nutrition Assistance Program to Make Healthy Purchases in the Online Food Retail Ecosystem.

The United States (U.S.) Department of Agriculture (USDA)-administered Supplemental Nutrition Assistance Program (SNAP) made substantial changes in response to the coronavirus disease 2019 (COVID-19) pandemic. These changes highlight the need to identify the digital literacy skills and capacities of SNAP adults to purchase healthy groceries online. We conducted a scoping review of four electronic databases, Google and Google Scholar to identify studies that measured food and nutrition literacy outcomes for U.S. adults. We applied a multi-dimensional digital food and nutrition literacy (MDFNL) model to assess six literacy levels and components. Of 18 studies published from 2006-2021, all measured functional and interactive literacy but no study measured communicative, critical, translational, or digital literacy. Six studies examined SNAP or SNAP-Education outcomes. Adults with higher food or nutrition literacy scores had better cognitive, behavioral, food security and health outcomes. We suggest how these findings may inform research, policies, and actions to strengthen the multi-dimensional literacy skills of SNAP participants and SNAP-eligible adults to support healthy purchases in the online food retail ecosystem.

Resurgence of Rotavirus Genotype G12 in St. Louis During the 2014-2015 Rotavirus Season.

BACKGROUND: Rotaviruses are a leading cause of gastroenteritis. Rotavirus vaccination has dramatically reduced rotavirus occurrence; however, we have noticed mild to moderate recurrences in the St. Louis area in alternate years. In 2013, we found rotavirus genotype G12 to be the dominant strain in the St. Louis region. In this study, we again determined the distribution of genotypes and ascertained vaccine history in patients infected with rotavirus G12 during the 2014-15 season. METHODS: Samples submitted to the St. Louis Children's Hospital Microbiology Laboratory were tested for rotavirus using an antigen assay. We determined the VP7 genotype using amplicon sequence analysis. We determined genome sequences using high-throughput sequencing. We evaluated rotavirus immunization records when available. RESULTS: Of 30 typed viruses from 2014-15, 29 were G12 (97%). Whole-genome sequencing revealed few changes from G12 viruses analyzed in 2012-13. VP4 and VP7 sequences were >99% identical to previously sequenced G12 strains from St. Louis, and immune epitopes were conserved. Vaccination histories were available from 17 patients. Of these, 4 had been vaccinated, 3 had received incomplete vaccination or had a vaccine history that could not be confirmed, and 10 had not been vaccinated. CONCLUSIONS: G12 re-emerged as the predominant rotavirus genotype in 2014-15, comprising a higher percentage of cases than in 2012-13. The majority of patients with G12 and available vaccination histories were unvaccinated. There was no genomic evidence to indicate that the G12 strains in St. Louis had evolved to escape vaccine protection. Our work emphasizes the need for continued surveillance.

Immunocompetent properties of human osteoblasts: interactions with T lymphocytes.

UNLABELLED: We sought to determine whether osteoblasts (OBs) can serve as accessory cells (ACs) for T-cell activation and whether T cells directly activate OB production of IL-6, using primary human OBs (NHOst), the transformed fetal osteoblast line hFOB1.19, and an osteosarcoma line SaOS-2. Robust, bidirectional activating interactions were shown using each of these three human ostoblast lines. INTRODUCTION: Osteoblasts (OBs) could come into contact with lymphocytes during inflammatory joint destruction and fracture repair. MATERIALS AND METHODS: We used several in vitro assays to assess the ability of T cells and OBs to interact in the generation of immune and inflammatory responses. RESULTS: By flow cytometry, three OB cell lines all were found to express ligands for T-cell co-stimulation. The integrin ligand CD54/ICAM-1 was constitutively expressed by hFOB1.19 and NHOst and was upregulated on SaOS-2 by IFN-gamma. MHC Class II was upregulated on all three lines by IFN-gamma. CD166/ALCAM, a ligand of the T-cell molecule CD6, was constitutively expressed on all three lines. A second putative CD6 ligand designated 3A11 was expressed on hFOB1.19 and NHOst, but not consistently on SaOS-2. The ectoenzyme CD26 (dipeptidyl peptidase IV) was expressed on hFOB1.19 and NHOst, but not on SaOS-2. All three cell lines presented superantigen to T cells, especially after treatment with IFN-gamma. Superantigen presentation was inhibited by antibodies to the leukocyte integrin CD11a/CD18 (LFA-1), MHC Class II, and CD54/ICAM-1. T cells, particularly when cytokine activated for 7 days before co-culture, stimulated all three osteoblast lines to produce interleukin (IL)-6, and this effect was boosted when IL-17 was added to the co-cultures with either resting T cells or cytokine-activated T cells. CONCLUSIONS: Bidirectional activating interactions are readily shown between human T cells and several types of human OBs. The expression by OBs of ligands for the T cell-specific molecule CD6, as well as other molecules involved in immune interactions, strongly suggests that such in vitro interactions are representative of physiologic or pathologic events that occur in vivo.

Investigation of an adaptive treatment regime for prostate radiation therapy.

PURPOSE: Changes in body contour during the course of radiation therapy can compromise the accuracy of treatment delivery. In prostate radiation therapy these changes can result from the daily patient positioning as well as the deformation of the body shape between treatment days and simulation. This study investigates the feasibility of using an online correction method to account for interfraction body contour changes prior to daily delivery of prostate radiation therapy based on cone beam computed tomography (CBCT) imaging. METHODS AND MATERIALS: This is a retrospective study where 5 prostate patients who received intensity modulated radiation therapy were selected. Patients were selected from a cohort who demonstrated repeated minor (1-2 cm) variations in body contour between planning CT and daily CBCT. Pretreatment CBCT images were used to calculate the "treated" dose and investigate the deviations from prescription caused by changes in body contour. A simple tissue maximum ratio correction was then applied to each field to calculate the "adapted" dose, which accounts for physical changes in path length on the central axis. A comparison was made between the treated and adapted scenarios. RESULTS: For this cohort, 22 of the 64 analyzed fractions showed body contour changes ≥1 cm. The treated doses showed deviations from prescribed dose ranging from -2.4% to 1.3% per fraction. After the plan was adapted, 4 of the 5 cases showed an improvement (P < .05) in target dose for the entirety of treatment. The 1 patient not showing improvement had negligible dose change due to contour variation. CONCLUSIONS: This online adaptive strategy is a promising approach to account for changes in body contour during prostate intensity modulated radiation therapy.

Hyperinsulinism in a neonate.

A male patient was born small for gestational age (SGA) at 33 weeks with a birth weight of 1,663 grams (< 10th percentile) and length 43 cm (10th percentile) to a 38-year-old G5P4 mother by cesarean section due to non-reassuring fetal heart tones. Prior to delivery, his mother experienced decreased fetal movement and decelerations. At birth, he was initially well-appearing and vigorous, with Apgar scores of 7 and 8 at 1 and 5 minutes, respectively. The physical examination was unremarkable--no skin findings, no facial anomalies, good tone, and the anterior fontanelle was soft and flat. The placenta, although noted to be healthy in appearance on prenatal ultrasounds, was atrophic and calcified by gross examination. The patient developed respiratory distress 1 hour after birth and was found to have a blood glucose level of 24 mg/dL. Following an intravenous (IV) bolus of 10% dextrose in water (D10W) of 2 mL/kg, his glucose was 20 mg/dL. He was started on IV fluids with a glucose infusion rate (GIR) of 7.3 mg/kg/minute, with a subsequent rise in blood glucose to 46 mg/dL. Due to prematurity, respiratory distress, and persistent hypoglycemia, a diagnostic evaluation was initiated for possible sepsis, including a complete blood count with differential and platelet count and blood cultures. The patient was started empirically on IV ampicillin and gentamicin. The patient was subsequently found to have thrombocytopenia, hypomagnesemia, and hyponatremia on laboratory evaluation and was transferred to our neonatal intensive care unit (NICU) for further care.

Pregnancy and treatment outcome in a patient with left ventricular non-compaction.

Left ventricular non-compaction (LVNC) is a rare form of cardiomyopathy. This case reviews a woman with familial LVNC (EF 45%, NYHA class I, evidence of non-sustained ventricular tachycardia pre-pregnancy) who had significant decompensation with heart failure in the third trimester that required early delivery. Deterioration in symptoms and LV function 7 days after delivery required further hospitalization and aggressive treatment. Suppression of lactation with bromocriptine, together with standard heart failure management, has allowed recovery and return to full activities and work. Acknowledged adverse risk factors in LVNC are considered, and pre-pregnancy risk assessment is reviewed. There is no specific treatment for LVNC in pregnancy besides the usual management of dilated cardiomyopathy. This is the ninth case report of LVNC in pregnancy reported in the literature.
