Association of urinary phthalate metabolite concentrations with body mass index and waist circumference: a cross-sectional study of NHANES data, 1999–2002

BACKGROUND: Although diet and activity are key factors in the obesity epidemic, laboratory studies suggest that endocrine disrupting chemicals may also affect obesity. METHODS: We analyzed associations between six phthalate metabolites measured in urine and body mass index (BMI) and waist circumference (WC) in National Health and Nutrition Examination Survey (NHANES) participants aged 6–80. We included 4369 participants from NHANES 1999–2002, with data on mono-ethyl (MEP), mono-2-ethylhexyl (MEHP), mono-n-butyl (MBP), and mono-benzyl (MBzP) phthalate; 2286 also had data on mono-2-ethyl-5-hydroxyhexyl (MEHHP) and mono-2-ethyl-5-oxohexyl (MEOHP) phthalate (2001–2002). Using multiple regression, we computed mean BMI and WC within phthalate quartiles in eight age/gender specific models. RESULTS: The most consistent associations were in males aged 20–59; BMI and WC increased across quartiles of MBzP (adjusted mean BMI = 26.7, 27.2, 28.4, 29.0, p-trend = 0.0002), and positive associations were also found for MEOHP, MEHHP, MEP, and MBP. In females, BMI and WC increased with MEP quartile in adolescent girls (adjusted mean BMI = 22.9, 23.8, 24.1, 24.7, p-trend = 0.03), and a similar but less strong pattern was seen in 20–59 year olds. In contrast, MEHP was inversely related to BMI in adolescent girls (adjusted mean BMI = 25.4, 23.8, 23.4, 22.9, p-trend = 0.02) and females aged 20–59 (adjusted mean BMI = 29.9, 29.9, 27.9, 27.6, p-trend = 0.02). There were no important associations among children, but several inverse associations among 60–80 year olds. CONCLUSION: This exploratory, cross-sectional analysis revealed a number of interesting associations with different phthalate metabolites and obesity outcomes, including notable differences by gender and age subgroups. Effects of endocrine disruptors, such as phthalates, may depend upon endogenous hormone levels, which vary dramatically by age and gender. Individual phthalates also have different biologic and hormonal effects. Although our study has limitations, both of these factors could explain some of the variation in the observed associations. These preliminary data support the need for prospective studies in populations at risk for obesity.National Institutes of Environmental Health Sciences (R21ES013724

East meets west: when the Islamic and Gregorian calendars coincide

Recent research has documented that at the time of religious celebrations in Muslim countries, such as Ramadan, there is a “festival” effect in share returns. In the Gregorian calendar, December is also a time of celebration and festivities which may be associated with patterns in the behaviour of security prices. Further, the first month of the year in the Islamic calendar, Muharram, is a time of sadness and mourning for some believers, and there may be an effect when the Islamic first month of the year overlaps with the first month of the Gregorian year - January. Over a 33-year cycle, each Islamic month falls in a Gregorian month for about 5–6 consecutive years; when this happens, an Islamic (Eastern) calendar effect may interact with a Gregorian (Western) calendar effect. The current paper addresses this issue by examining the behaviour of share returns and volatility for individual companies listed in Muslim countries’ stock exchanges when the two calendars coincide for: (i) religious festival effects; (ii) first-month-of-the-year effects; and (iii) the two most common effects reported in the Islamic and Gregorian calendars (Ramadan and January). The results show that the Western and Eastern effects interact more prominently in larger companies and in larger or more developed markets

Possible predictive markers in surgical decision making in patients with degenerative or isthmic lumbar spondylolisthesis

Background: Although age, comorbidity, duration and severity of symptoms, slippage degree, and flexion-extension slipping stability during X-ray imaging are effective in making a surgical decision in patients with spondylolisthesis, these factors are rarely based on definitive evidence. The aim of this study was to determine the efficacy of clinical, radiological and biochemical findings in surgical decision making in these patients. Materials and Methods: Patients’ data including age, gender, degree and type (i.e. degenerative or isthmic) of the spondylolisthesis, urinary incontinence, neurogenic claudication were recorded. Radiological imaging studies (lumbar dynamic X-ray, computed tomography, magnetic resonance imaging), serum glucose, C-reactive protein and erythrocyte sedimentation rate values of the patients obtained during hospital admissions were evaluated. Results: Forty patients were followed conservatively and 12 patients were treated surgically. Degenerative spondylolisthesis was seen in 22 patients. Nine patients had neurogenic urinary incontinence and 19 patients had neurogenic claudication. When the patients were divided into two groups with and without surgical treatment, the presence of the pars defect, slipping distance in a neutral position and slipping distance in flexion position was significantly different between groups. A positive correlation was found between pars defect and surgical treatment. Likelihood ratio test results revealed that the presence of pars defect, neurogenic claudication and neurogenic urinary incontinence could be the best parameters in decision making the surgical treatment. Conclusion: The presence of pars defect, neurogenic claudication and urinary incontinence could be the best parameters that may help the surgeon to make the surgical treatment decision

Performing the screw fixation from C3 to odontoid process in a patient with Klippel-Feil syndrome and type II odontoid fracture

A 56-year-old female patient was admitted with a history of pain during neck movements after cervical injury. Computerized tomography scan revealed type II odontoid fracture and fusion anomaly between C2 and C3 vertebrae. At surgery, the anteroinferior part of C2 vertebra corpus could not be reached; therefore, transodontoid screw was advanced from C3 vertebra toward odontoid process. At follow-up examination, the complaints of the patient had recovered, and fracture line was completely fused. Advancing screw from C3 to odontoid process via anterior cervical approach could be thought an alternative treatment option in the patient with short neck caused from vertebra fusion anomaly and/or obesity

BILATERAL SUBDURAL HEMATOMA AFTER VENTRICULOPERITONEAL SHUNT SURGERY

WOS: 000500774900009Background: Bilateral subdural hematoma (SDH) following ventriculoperitoneal (V/P) shunt application was discussed in present case. Case Report: 8-year-old girl was operated due to thoracolumbar meningomyelocele immediately after birth. V/P shunt was inserted in right posterior parietal region due to hydrocephalus when she was 3 month-old. At age of 3 years, V/P shunt dysfunction was considered, and second V/P shunt was inserted in left posterior parietal region. One year after, patient was reevaluated, and CT images showed bilateral subacute SDH. Hematoma evacuation was not considered, but right ventricular catheter was ligated. At four years follow-up, no additional neurological impairment was observed in patient and CT scan revealed that SDHs were retracted greatly. Concusion: It should be kept in mind that SDH could develop after V/P shunt surgery. Additionally, it could be said that one of most important factor in determination of treatment of this complication was primarily neurological examination findings of patient

Can Routine Blood Biochemistry Parameters be Predictive Prognostic Marker(s) in Operated Patients with Meningioma WHO Grade 1?

Background Today, there is a need for new and independent additional advanced markers that can predict the prognosis of meningioma patients, postoperatively. The present study aimed to find out postoperative short-term prognostic markers in patients with meningioma using their demographic data and routine blood biochemistry findings evaluated preoperatively. Methods The Glasgow Coma Scale (GCS), and Glasgow Outcome Scale (GOS) scores of the patients were recorded. Additionally, preoperatively obtained serum glucose, C-reactive protein (CRP), sodium, potassium, creatinine, blood urea nitrogen, aspartate aminotransferase (AST), alanine aminotransferase, and hemoglobin level values, platelet, leukocyte, neutrophil, lymphocyte, eosinophil, basophil, and monocyte count results, erythrocyte sedimentation rate (ESR), neutrophil-lymphocyte ratio, platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) values were evaluated. Results In the present study, 23 operated patients with meningioma World Health Organization (WHO) grade 1 (17 females, 6 males) were included. Correlation test results revealed that the GCS score, platelet count, and serum potassium level values could directly predict the short-term prognosis of these patients. Additionally, these test results suggested that the lymphocyte, monocyte, and eosinophil count values, PLR, LMR, ESR, serum glucose, CRP, and AST level values could be indirect markers in predicting the short-term prognosis. However, likelihood ratio test results revealed that only monocyte count value, LMR value, and serum CRP level value could be the markers for prediction of the short-term prognosis. Conclusion At the end of the present study, it was concluded that the monocyte count value, LMR value, and serum CRP level value could be the best markers in predicting the short-term prognosis of the operated meningioma patients

Analysis of biochemical laboratory values to determine etiology and prognosis in patients with subarachnoid hemorrhage: a clinical study

KISA, Ucler/0000-0002-8131-6810; BAKAR, BULENT/0000-0002-6236-7647WOS: 000459561000008PubMed: 30417744Objectives: The aim of this study was to establish prognostic and predictive markers in patients with subarachnoid hemorrhage (SAH) using simple laboratory methods. Methods: A retrospective examination was made of patients with SAH diagnosed secondary to isolated head trauma, isolated anterior communicating artery aneurysm rupture, and angiography-negative SAH. Age, gender, Glasgow Coma Scale (GCS) scores, and Fisher's grade scores, Glasgow Outcome Scale (GOS) scores, leukocyte count, neutrophil count, lymphocyte count, platelet count, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio results (PLR) were evaluated. Results: NLR and PLR values, which were similar in patients with spontaneous SAH, were significantly high in patients with traumatic SAH. NLR and PLR values could be 80% sensitive and 75% specific for distinguishing traumatic SAH from spontaneous SAH. Eosinophil count was lower in patients with angiography-negative SAH and patients with aneurysmal SAH than in patients with traumatic SAH. Initially measured GCS score, Fisher's grade score, eosinophil, neutrophil and lymphocyte counts could be prognostic in all patients with SAH. Moreover, it was concluded that the initially measured number of eosinophils might be directly related to patient prognosis. The eosinophil count was generally found to be high in traumatic SAM patients and it was observed that this parameter could be predictive for these patients. Lymphocyte count and NLR values could be prognostic markers in patients with angiography-negative SAH. Conclusion: NLR, PLR and eosinophil count values could be predictive for etiological factors (traumatic SAH or spontaneous SAH) of patients who were admitted unconscious to the emergency room with SAH detected on radiological imaging
