Postpartum depression: Identifying associations with bipolarity and personality traits. Preliminary results from a cross-sectional study in Poland

The goals of this study have been to determine the prevalence of the bipolar spectrum features in the population of women with postpartum depression (PPD) symptoms, as well as to analyze the personality differences between putative ‘unipolar’ and ‘bipolar’ PPD subjects. The sample enrolled into the cross-sectional study consisted of 344 women at 6–12 weeks postpartum. The authors used the Edinburgh Postnatal Depression Scale (EPDS; cut-off score: 13 pts.) for the assessment of the PPD symptoms, the Mood Disorder Questionnaire (MDQ; cut-off scores: 7 or 8 pts.) for diagnosing the bipolar features, and the NEO-Five Factor Inventory (NEO-FFI) for the assessment of personality traits. The EPDS-positive subjects were more likely to score positively on the MDQ, as compared to the EPDS-negative ones. The EPDS-positive subjects who also scored ≥8 pts. on the MDQ were characterized by higher index of neuroticism, as compared to those who scored positively on the EPDS only. The results suggest that the presence of PPD symptoms is related to significantly higher scores of bipolarity and neuroticism. The more robust trait of neuroticism might be a marker of the ‘bipolar’ PPD, as compared to the ‘unipolar’ form of the disorder.     

Angiopoietin-2 as a biomarker of non-ST-segment elevation myocardial infarction in patients with or without type 2 diabetes

IntroductionAngiopoietin-2 (Ang-2) is a novel marker of coronary artery disease (CAD) and diabetes (DM). The aim was to evaluate Ang-2 as a potential new biomarker of non-ST elevation myocardial infarction (NSTEMI) in patients with or without type 2 DM (T2DM).Material and methodsThis was a multi-center, prospective study that included 138 (males: 91/66%) consecutive patients hospitalized due to NSTEMI, T2DM, or different cardiac disorders. The subjects were divided into four study groups: group A: 28 patients with NSTEMI and T2DM; group B: 47 patients with NSTEMI without T2DM; group C: 31 patients with T2DM, without a history of CAD; group D: 32 patients as a control group. Patients with NSTEMI underwent urgent coronarography. Clinical characteristics including biomarkers (hs-CRP, hsTnT, NT-proBNP, VEGF, HbA_1c), SYNTAX SCORE, type of intervention (PCI vs. CABG), and number of implanted stents were taken into account in the analysis.ResultsSerum Ang-2 concentrations were significantly higher in patients with NSTEMI (group A: 1769 pg/ml; group B: 1757 pg/ml) and patients with T2DM (group C: 1993 pg/ml) as compared to the patients without CAD and without T2DM (group D: 866.8 pg/ml; p < 0.05). The prognostic accuracy of Ang-2 in NSTEMI diagnosis was determined with the area under the ROC curve (area under curve (AUC) = 0.63).ConclusionsAngiopoietin-2 serum concentration is elevated in the presence of NSTEMI in patients with and without T2DM and does not correspond to the degree of myocardial injury and hemodynamic status. Ang-2 remains elevated also in patients with T2DM without a history of CAD.     

The conventional versus automated measurement of blood pressure in the office (CAMBO) trial: masked hypertension sub-study

OBJECTIVES:: To determine the prevalence of masked hypertension [normal office blood pressure (BP) with high awake ambulatory BP] using automated office BP (AOBP) or conventional manual office BP (MOBP) measurement in routine clinical practice. METHODS:: The prevalence of masked hypertension was evaluated on three consecutive visits during a median 6 months period in patients with systolic hypertension randomized to management with AOBP (n?=?140) or continued conventional MOBP (n?=?112) in routine primary care practice. AOBP was recorded using the automated BpTRU device with the patient resting alone in a quiet examining room. All patients underwent 24-h ambulatory BP monitoring. RESULTS:: The prevalence of masked hypertension on any one of three visits calculated using only SBP varied between 12 and 17% in the AOBP group compared with 19 and 22 % in the MOBP group. Masked hypertension was present on both of the first two visits in 7 and 12% and on all three visits in 6 and 7% of AOBP and MOBP patients, respectively. The prevalence for masked hypertension based upon both SBP and DBP was similar being 11-15% for AOBP and 19-20% for MOBP patients on single visits, but decreased to 6 and 10% when readings from the first two visits were used and to 4 and 6% when all three visits were used for the AOBP and MOBP groups, respectively. CONCLUSION:: The prevalence of masked hypertension is lower with AOBP compared with MOBP. The number of patients with masked hypertension decreases if the criteria for having this condition need to be met on multiple visits.     

Mild Elevation of Fasting Plasma Glucose is a Strong Risk Factor for Postoperative Complications in Gastric Bypass Patients

Background: Bariatric surgery may be associated with surgical complications. The aim of the study was to identify significant risk factors for postoperative complications in patients undergoing Roux-en-Y gastric bypass (RYGBP). Methods: The study consisted of 75 consecutive patients undergoing RYGBP. Full medical examination was performed, and the following parameters were assessed in the fasting state: plasma glucose, insulin, leptin, serum lipids, liver function tests, and lipoprotein Lp(a). All subjects had oral 75 g glucose tolerance test before the surgery. All complications occurring within 6 months after the RYGBP were recorded. The patients were divided into Group 1 - patients in whom complications occurred, and Group 2 - patients with no complications in the 6-month period. Results: Postoperative complications occurred in 16 patients (wound infection, hernia, splenic injury, gastro-jejunal obstruction, duodenal ulcer, lower limb deep vein thrombosis). 3 significant risk factors for postoperative complications within 6 months after gastric bypass were found: 1) fasting plasma glucose ≥ 6.0 mmol/l (OR 11.0; 95% confidence interval (CI) 2.1-77.3), 2) age ≥40 years (OR 5.89, 95% CI 1.35-29.4), and 3) BMI ≥45 kg/m² (OR 4.1, 95% CI 1.04-17.2). Conclusion: RYGBP is associated with increased risk of developing early postoperative complications in subjects with even slightly elevated fasting plasma glucose, age ≥40 and BMI ≥45 kg/m².

The role of sentinel node detection techniques in vulvar and cervical cancer

The sentinel node is the first lymph node that receives the lymph drainage from the primary tumour. The pathological status of the sentinel node should reflect the histopathology of the entire regional lymph drainage area--both vulvar and cervical cancer spread through the lymphatic system. In gynaecological oncology recent studies have confirmed the utility of the sentinel node concept in vulvar and cervical cancer. Three techniques for sentinel node localisation are available. The preoperative lymphoscintigraphy and intraoperative hand-held gamma probe detection require the administration of the technetium-99m-labelled colloid around the tumour. The other method is based on the injection of the patent blue dye--during the surgery of the sentinel node because of the dye uptake becomes visible. Following detection, the sentinel lymph node can be removed separately and assessed with ultrastaging and immunohistochemical staining. In the early stages of vulvar and cervical cancer the lymph nodes metastases rate is relatively low--in most cases lymphadenectomy is not necessary. The determination of the regional lymph nodes' pathological status may limit the extent of the surgical treatment. The sentinel node detection rate is relatively high and depends on the applied technique. This technique may play an important role in the treatment of vulvar and cervical cancer. This paper describes the details of sentinel node identification and reviews the literature.     

Transcranial Magnetic Stimulation: Use of Motor Evoked Potentials in the Evaluation of Surgically Induced Spinal Cord Ischemia

Abstract

We evaluated transcranial magnetic stimulation producing motor evoked potentials (TMS MEP) as a method to detect spinal cord ischemia during surgery for thoracoabdominal aneurysms. Four groups of swine were subjected to different types of surgically-induced ischemia. TMS MEP and neurological function were assessed at baseline, immediately after the ischemic insult and after four hours of reperfusion/post-ligation. Cross-clamping of the aorta in groups A & B resulted in the disappearance and subsequent reappearance of TMS MEP with significantly prolonged latencies in most animals and variable neurological function. Ligation of intercostal arteries produced no changes in TMS MEP or neurological function (group C). However, after ligation of intercostal and lumbar arteries, group D demonstrated no reappearance of TMS MEP and severe neurological deficits. TMS MEP can provide rapid detection of global spinal cord ischemia and can also predict local devascularization injury. (J Spinal Cord Med 1997; 20:395-401)     

Steroid withdrawal at 3 months after kidney transplantation: a comparison of two tacrolimus-based regimens

The 6 month prospective, randomized study compared the steroid-sparing potential of two tacrolimus-based regimens after renal transplantation. A total of 489 patients were randomized (1:1) to receive tacrolimus/mycophenolate mofetil (MMF)/steroids (n = 243; group Tac/MMF/S) or tacrolimus/azathioprine/steroids (n = 246; group Tac/Aza/S). At 3 months, steroids were tapered off in 267 (54.6%) patients free from steroid-resistant acute rejection and with serum creatinine concentrations <160 micromol/l. The incidence of biopsy-confirmed acute rejection at month 3 was lower in group Tac/MMF/S compared with group Tac/Aza/S (18.1% vs. 26.0%,P = 0.035). Moreover, more patients in the Tac/MMF/S group met the criteria for steroid withdrawal than in the Tac/Aza/S group (60.5% vs. 48.8%; P < 0.01). The incidence of acute rejection during months 4-6 was low in all groups, both for patients on steroid-free dual therapy (Tac/MMF: 2.7%, Tac/Aza: 0.8%) and for patients who continued steroid maintenance therapy (Tac/MMF/S: 3.5%, Tac/Aza/S: 7.1%). Moreover, kidney function was well preserved in steroid-free patients with month 6 median serum creatinine levels of 119.5 micromol/l (Tac/MMF), and 115.1 micromol/l (Tac/Aza). For patients who continued to receive steroids, month 6 median creatinine levels were 130.5 micromol/l (Tac/MMF/S) and 132.8 micromol/l (Tac/Aza/S). The criteria for the selection of patients to discontinue steroids were adequate. Both tacrolimus-based regimens allowed the safe discontinuation of steroids in low-risk patients at month 3. The Tac/MMF combination was superior in the prevention of acute rejections and more patients met the chosen criteria for steroid withdrawal.     

Prednisone dosing per body weight or body surface area in children with nephrotic syndrome—is it equivalent?

The current guidelines recommend a dosage of prednisone of 60 mg/m² body surface area per day (BSA PRED) for the initial therapy of nephrotic syndrome (NS). Alternatively, a dosage of 2 mg/kg body weight per day (W PRED) can be used. We hypothesized that the BSA PRED and W PRED are not equivalent and analyzed the differences between BSA PRED calculated with various formulas for body surface area (BSA), W PRED and the dose of prednisone prescribed for our patients. We performed a retrospective chart review of the patients at their initial presentation of NS. Thirty-three children were included, of median age 3.34 years at presentation. The W PRED was significantly lower than BSA PRED (P < 0.05), with a median W PRED:BSA PRED ratio of 0.85 [interquartile range (IQR) 0.8 to 0.9]. The difference between W PRED and BSA PRED decreased proportionally to patients’ weights up to 30 kg. No differences were noted between the various BSA formulas using both weight and height for the calculation of BSA. The Bland–Altman analysis showed a proportional error between W PRED and BSA PRED up to the average daily dose of 60 mg, with a mean bias of 0.86 (95% limits of agreement = 0.68 to 1.05). Ten out of the 33 patients (30%) were given a lower than recommended BSA PRED dose by more than 5 mg/day. In conclusion, the dosage of prednisone at 2 mg/kg per day versus 60 mg/m² per day is not equivalent for patients with weights <30 kg and/or dose <60 mg/day.
