STUDY DESIGN: A single-center, prospective study. OBJECTIVE: To investigate the effect of rib anomaly on surgical curve correction outcome in congenital scoliosis. SUMMARY OF BACKGROUND DATA: The presence of rib anomalies may complicate surgical correction of congenital scoliosis. The outcome of surgical correction, however, has not been documented in scoliotic patients with and without rib deformity. METHODS: Percent Cobb angle decrease (CAD) after operation was calculated in 94 patients with congenital scoliosis...

BACKGROUND: The spectral analysis of the heart rate variability (HRV) shows a decrease in the power of the high frequency (HF) component in preeclamptic pregnancy compared with normal pregnancy; such a decrease is associated with an increase in the low frequency (LF) and the very low frequency (VLF) power. The physiological interpretation is that preeclamptic pregnancy is associated with a facilitation of sympathetic regulation and an attenuation of parasympathetic influence of HR compared with non-pregnancy and normal pregnancy...

BACKGROUND: Primary immunodeficiency diseases (PID) are heterogeneous group of inherited disorders mainly characterized by recurrent infections leading to several times hospital admissions. The economic impact of PID is a challenging issue; therefore, this study was designed to determine the medical costs of hospitalizations in this group of patients as an indicator of the direct cost of these diseases. METHODS: One hundred and ten children with PID hospitalized in the Children's Medical Center Hospital, Tehran, Iran were included in this study during Jan 2011 and Jan 2012...

BACKGROUND: Schizophrenia is a typical N-methyl-d-aspartate receptor (NMDA-R) hypofunction disorder. Decreased d-serine (d-Ser) levels in the periphery occur in schizophrenia and may reflect decreased availability of d-Ser to activate NMDA-R in the brain. OBJECTIVE: The objective of this study was to investigate the role of d-Ser metabolism in the pathogenesis of schizophrenia via biochemical assays and correlates, the serum level of d-Ser, d-serine racemase (SR) (responsible for its formation from l-serine [l-Ser]) and d-amino acid oxidase (DAAO) (responsible for its catabolism), among different clinical types of schizophrenia patients...

Translocator protein (TSPO) is involved in modulating mitochondrial permeability transition pore (mPTP) opening/closure leading to either apoptotic cell death via opening of mPTP or cell protection mediated by mPTP blocking and hence intercepting mPTP induced apoptosis. Herein, 2-(2-aryloxyphenyl)-1,4-dihydroisoquinolin-3(2H)-one derivatives have been designed and synthesized as new modulators for amyloid-β-induced mPTP opening. Among all, compound 7c remarkably enhanced mPTP opening while compound 7e showed the highest mPTP blocking activity...

We analyzed phytolith and diatom remains preserved at 45 Miocene and Pliocene localities dated between 8 and 1 Ma in northern Chad (16-17°N). Some of these localities yielded cranial remains, lower jaws, and teeth of the hominin species Australopithecus bahrelghazali (∼3.6 Ma) and Sahelanthropus tchadensis (∼7 Ma). Of the 111 sediment samples analyzed, 41 yielded phytoliths, 20 yielded diatoms, and seven yielded both phytoliths and diatoms. Freshwater planktonic and tychoplanktonic diatom species, indicative of lacustrine conditions, are dominant (>91%) in the samples...

This study aimed to investigate factors affecting fruit and vegetables (FAVs) intake among Bangladeshi adults. Dietary data of 9275 adults from the Bangladesh Noncommunicable Disease Risk Factor Survey 2010 were analyzed. The mean age of the respondents was 42.4 (±13.5) years. Multistage cluster sampling was applied to identify samples. Demographics, personal habits, physical activity, diet, and anthropometric data were collected using the WHO-STEPs questionnaire. Average daily intake of <5 servings of FAVs combined was considered to be low FAV consumption, and its prevalence was 82...

INTRODUCTION: Amyand hernia (AH) is a rare type of hernia characterized by the presence of appendix vermiformis in the inguinal hernial sac. It is rarely reported in women. PRESENTATION OF CASE: We presented a case of a 60- year old woman who was admitted initially with an abdominal wall abscess and found to have perforated appendix in the right inguinal hernia. The patient underwent standard open appendectomy and the post-operative course was uneventful. DISCUSSION: The initial presentation of our case as an abdominal wall abscess is rare in the contemporary literature...

PURPOSE: With an increasing demand for more accurate preoperative staging methods for colon cancer, we aimed to compare preoperative tumour (T)- and nodal (N)-stage in patients with left-sided colon cancer by endoscopic ultrasonography (EUS) and computed tomography (CT) with post-operative histology as gold standard. METHODS: A total of 44 patients were prospectively recruited at Herlev and Roskilde University Hospitals during November 2014-January 2016. Thirty-five patients were included in the final analysis and underwent EUS, CT and surgery within 2 weeks...

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the relationship between major dietary patterns and the risk of insulin resistance (IR) among an urban Iranian population. METHODS AND STUDY DESIGN: In this longitudinal study, 802 adult men and women were studied within the framework of Tehran Lipid and Glucose Study. Fasting serum insulin and glucose were measured at baseline and again after a 3-year of followup. The usual dietary intakes were assessed using a validated 168 item semi-quantitative food frequency questionnaire and major dietary patterns were obtained using principal component analysis...

BACKGROUND: In patients with primary hyperparathyroidism (PHPT) and preoperative imaging suggesting a solitary parathyroid adenoma (SPA), focused parathyroidectomy is most often curative. Even so, large studies show up to 3% of patients experience persistent or recurrent PHPT. Unilateral neck exploration (UNE) aiming to identify the SPA and the other ipsilateral parathyroid may reduce this failure rate. We hypothesized that: (i) minimally invasive video-assisted (MIVA) approach would facilitate UNE and (ii) this would be a clinically relevant strategy...

Carboplatin is a chemotherapeutic agent used against various malignancies such as ovarian carcinoma. The aim of this study is to improve the therapeutic efficacy of carboplatin using pegylated liposomal nanocarriers. Nanoparticles were synthesized using thin film hydration technique and characterized for shape morphology, particle size, zeta potential and drug-release properties. In the next step, A2780S and A2780CP ovarian cancer cell lines were used to determine the efficacy of nanodrug by MTT assay. The particle size and zeta potential of nanodrug were measured 244...

Network models of healthcare systems can be used to examine how providers collaborate, communicate, refer patients to each other, and to map how patients traverse the network of providers. Most healthcare service network models have been constructed from patient claims data, using billing claims to link a patient with a specific provider in time. The data sets can be quite large (106-108 individual claims per year), making standard methods for network construction computationally challenging and thus requiring the use of alternate construction algorithms...
