TL;DR: Several factors, including the severity of physical symptoms of NVP and psychosocial factors, are associated with the need for hospital care.
Abstract: Objectifs: Caracteriser une cohorte de femmes enceintes ayant eu besoin de soins hospitaliers en raison de nausees et vomissements gravidiques (NVG) et definir les variables qui pourraient servir de predicteurs du besoin de soins hospitaliers. Conception: Etude retrospective par observation. Methodes: Entre 1996 et 1997, on a invite les femmes souffrant de NVG a composer le numero de la «NVP Healthline» du Motherisk Program de Toronto. Apres avoir obtenu le consentement verbal des interessees, des conseillers ayant recu la formation necessaire les ont interviewees au moyen d'un questionnaire structure portant sur leur experience de NVG au cours de grossesses anterieures. On a procede a des analyses unidimensionnelles et multidimensionnelles pour definir les facteurs susceptibles de predire le besoin de soins hospitaliers. Resultats: On a recrute au total 3201 femmes;1348 (43,8 %) ont eu besoin de soins a l'hopital (traitement a l'urgence, court sejour ou hospitalisation). On a etabli un lien significatif entre les caracteristiques suivantes et le besoin de soins a l'hopital: gravite des vomissements (plus de cinq fois par jour), utilisation de plus d'un antiemetique, primiparite, sentiment de depression, obstetricien comme prestateur de soins primaires et sentiment que les NVG avaient un effet sur la vie quotidienne du partenaire. Conclusions: On etablit un lien entre plusieurs facteurs, y compris la gravite des symptomes physiques de NVG et des facteurs psychosociaux, et le besoin de soins a l'hopital. Outre le traitement des symptomes physiques, il importe de se pencher sur d'autres facteurs associes aux NVG.

TL;DR: The plasma levels of captopril in a young patient given a small oral dose were determined by this HPLC method, which proved to be linear in the clinical range of 10–1,000 ng/ml.
Abstract: Captopril is an orally active inhibitor of angiotensin-converting enzyme. A rapid, accurate, and sensitive high-performance chromatography (HPLC) method is described for measuring plasma concentrations of captopril. Captopril was stabilized by forming an adduct with p-bromophenacyl bromide. This adduct was measured by HPLC using a C-18 reverse-phase column and monitoring the column effluent by ultraviolet absorption at 260 nm. The method proved to be linear in the clinical range of 10-1,000 ng/ml. The plasma levels of captopril in a young patient given a small oral dose were determined by this method.

TL;DR: PregVit®, a supplement with lower iron content, has significantly decreased constipation rates as compared to 60 mg iron- Materna and has similar compliance rates.
Abstract: Background
Prenatal micronutrient combinations with high iron content are associated with high rates of gastrointestinal symptoms. This coupled with nausea and vomiting of pregnancy results in women often discontinuing their multivitamins.
A new prescription supplement (PregVit®) that separates iron from calcium in two tablets – morning and evening, has lower elemental iron content (35 mg), but results in similar extent of iron absorption when compared to another supplement containing (60 mg) of elemental iron (Materna®). The objectives of this study were to compare tolerability and compliance with PregVit® vs. a supplement with high iron content (Materna®), in pregnant women.

TL;DR: Despite greater perceived stress, TMD cases had lower hair cortisol concentrations than controls and the 2 measures of stress were weakly and negatively correlated.
Abstract: Purpose: Perceived stress is associated with temporomandibular disorder (TMD), but whether cortisol levels are elevated in individuals with TMD is unknown. We hypothesized that cortisol concentration, a biomarker of hypothalamic-pituitary-adrenal (HPA) axis function, was elevated in TMD cases relative to controls, and that perceived stress was positively correlated with cortisol concentration. Methods: In this case control study, TMD case status was determined by examiners using TMD Research Diagnostic Criteria. Participants (n=116) aged 18 to 59 years were recruited from within a 50 mile radius of the University of North Carolina at Chapel Hill. Following examination, cases (n=45) and controls (n=71) completed the 14-item Perceived Stress Scale using a reference interval of the past 3 months. Approximately 100 strands of hair were cut from the posterior vertex segment of their scalp. The 3 centimeters of hair most proximal to the scalp was analyzed with a commercially available salivary cortisol enzyme immunoassay adapted for hair cortisol. This length corresponds to the last 3 months of systemic HPA axis activity. Results: TMD cases perceived higher stress than controls (p=0.001). However, hair cortisol concentration was lower in TMD cases than controls (p Conclusion: Despite greater perceived stress, TMD cases had lower hair cortisol concentrations than controls and the 2 measures of stress were weakly and negatively correlated.

TL;DR: In those older than age 50, systolic blood pressure of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP, and hypertension will be controlled only if patients are motivated to stay on their treatment plan.
Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.

TL;DR: These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care.
Abstract: XI. STRATEGIES FOR IMPROVING DIABETES CARE D iabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. Diabetes care is complex and requires that many issues, beyond glycemic control, be addressed. A large body of evidence exists that supports a range of interventions to improve diabetes outcomes. These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care. While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided. These standards are not intended to preclude more extensive evaluation and management of the patient by other specialists as needed. For more detailed information, refer to Bode (Ed.): Medical Management of Type 1 Diabetes (1), Burant (Ed): Medical Management of Type 2 Diabetes (2), and Klingensmith (Ed): Intensive Diabetes Management (3). The recommendations included are diagnostic and therapeutic actions that are known or believed to favorably affect health outcomes of patients with diabetes. A grading system (Table 1), developed by the American Diabetes Association (ADA) and modeled after existing methods, was utilized to clarify and codify the evidence that forms the basis for the recommendations. The level of evidence that supports each recommendation is listed after each recommendation using the letters A, B, C, or E.
