Reference ranges of anti-Müllerian hormone and interaction with placental biomarkers in early pregnancy: the Generation R Study, a population-based prospective cohort study.

Objective: The primary objective of this study is to establish maternal reference values of anti-Müllerian hormone (AMH) in a fertile multi-ethnic urban pregnant population and to evaluate the effect of gestational age. The secondary objective of this study is to explore the association between AMH and placental biomarkers. Design: This study was embedded in the Generation R Study, an ongoing population-based prospective cohort study from early pregnancy onwards. Setting: City of Rotterdam, the Netherlands, out of hospital setting. Patients: In 5806 women, serum AMH levels were determined in early pregnancy (median 13.5 weeks; 95% range 10.5-17.2). Intervention(s): None. Main outcome measures: Maternal AMH levels in early pregnancy and its association with placental biomarkers, including human chorionic gonadotrophin (hCG), soluble fms-like tyrosine kinase-1 (sFLT), and placental growth factor (PLGF). Results: A nomogram of AMH in early pregnancy was developed. Serum AMH levels showed a decline with advancing gestational age. Higher AMH levels were associated with a higher level of the placental biomarkers hCG and sFLT in early pregnancy. This last association was predominantly mediated by hCG. AMH levels were negatively associated with PLGF levels. Conclusion: In this large study, we show that AMH levels in early pregnancy decrease with advancing gestational age. The association between AMH and the placental biomarkers hCG, sFLT, and PLGF suggests a better placental development with lower vascular resistance in mothers with higher AMH levels. Hence, AMH might be useful in predicting adverse pregnancy outcomes due to impaired placental development.

Prevalence of active HCV infection and genotypic distribution among the general population of district Mardan, Pakistan / Prevalência de infecção HCV ativa a distribuição genotípica entre a população geral do distrito de Mardan, Paquistão

Hepatitis C virus (HCV) is the serious global public health burden of liver disease. Approximately 170 million people in the world are infected with (HCV). In Pakistan, where the disease has high occurrence rate. The present study envisages an up-to-date prevalence of HCV and genotypic distribution in the general population of Mardan District, Khyber Pakhtunkhwa (KP), Pakistan. The blood samples from 6,538 individuals including 3,263 males and 3,275 females were analyzed for hepatitis C surface antigen by Immuno-chromatographic test (ICT), Enzyme-linked immunosorbent assay (ELISA), and reverse transcription-polymerase chain reaction (PCR). It was found that 396 (12.13%) out of 3263 individuals contained antibodies in their blood against HCV, while among the different age groups, the highest incidences of HCV antibodies were found in the 31-40 age group (11.01%). The ICT positive samples were further screened by nested PCR to determine the existence of active HCV-RNA. It was identified that 7.11% (3263) of the total population (6538) tested was positive, among which the 461 (14.07%) females possessed antibodies in their blood against HCV. Our data showed total HCV infection in the investigated population was 5.78%. Higher percentage of HCV prevalence was detected in males than females in the age group 31-40 and 41-50. To compare the prevalence of HCV genotypes age-wise in male and female genotype 3a was found most prevalent genotype followed by 1a, 2a and 3b, respectively.

Cancer Pain, Anxiety, and Depression in Admitted Patients at a Tertiary Care Hospital: A Prospective Observational Study.

CONTEXT: Pain is the most common symptom in admitted cancer patients. The association between the severity of cancer pain and distress symptoms such as depression and anxiety is a subject of research. AIMS: The aim is to study the prevalence of pain, anxiety, and depression in admitted cancer patients and determine the association between pain and anxiety and depression at a tertiary cancer care institute. SETTINGS AND DESIGN: This was prospective observational study. SUBJECTS AND METHODS: We enrolled 393 cancer inpatients prospectively after written informed consent. Their disease details, presence, severity, and character of pain were recorded. Numerical Pain Scale was used for pain scores, self-reporting Hospital Anxiety and Depression Scale for anxiety and depression. STATISTICAL ANALYSIS USED: Normal data were analyzed with parametric, nonnormal with nonparametric methods, and categorical with the Chi-square test. RESULTS: The prevalence of moderate-to-severe pain was 41.5%, anxiety 20.3%, and depression 24.8%. Proportion of patients with anxiety and depression was 9.2% and 17.7% in patients with no pain; about 32.8% and 36.7% with severe pain, respectively (P < 0.000). In patients with no depression 6% had anxiety; with depression 44.9% had anxiety (P < 0.000). Odd's ratio to have anxiety and depression was 4.44 (95% confidence interval [CI] 2.0318-9.7024) and 2.92 (95% CI 1.5739-5.4186), respectively, in patients with pain as compared to no pain (P < 0.00). There was a positive correlation between pain, anxiety, and depression scores. CONCLUSIONS: There is strong association between the presence and severity of pain and distress symptoms such as anxiety and depression in admitted cancer patients.

Inhibin-A and inhibin-B in cyclic and pregnant mares, and mares with granulosa-theca cell tumors: Physiological and diagnostic implications.

Studies in mares have examined serum inhibin concentrations using immuno-assays unable to distinguish dimeric inhibin-A from inhibin-B isoforms. Inhibin-A and inhibin-B immuno-assays were used to investigate concentrations in cyclic mares, young and old (6 vs 19 years old, respectively) mares following hemi-ovariectomy, mares during pregnancy and in mares with confirmed granulosa cell tumors (GCTs). Mares with inter-ovulatory intervals of 26 days had ovulatory peaks of inhibin-A averaging 80 pg/mL with a mid-cycle nadir of 5 pg/mL. Inhibin-A and inhibin-B concentrations were highly correlated (r = + 0.79, P < 0.01) though peak and nadir concentrations of inhibin-B were not significantly different. However, the ratio of inhibin-A to inhibin-B (A/B) changed significantly through the cycle, highest at ovulation and <1 (more inhibin-B than -A) at mid-cycle. Two mares with grossly extended inter-ovulatory intervals demonstrated mid-cycle inhibin-A (and inhibin-B) excursions suggestive of follicular waves. Follicle-stimulating hormone was negatively correlated with inhibin-A and -B concentrations in all 6 mares. Hemi-ovariectomy in young mares resulted in a significant decrease in inhibin-A and inhibin-B concentrations one day later (P < 0.05) but older mares did not, suggesting a possible extra-ovarian source(s) of these hormones. Both inhibin isoforms dropped to very low levels during pregnancy (P < 0.0001), inhibin-A (P < 0.0001) more rapidly than -B (P < 0.05), so that inhibin-B became the predominant measured form throughout most of gestation (P < 0.05). Mares with confirmed GCTs had elevated inhibin-B concentrations more reliably than inhibin-A but neither inhibin-A or -B was correlated with anti-Müllerian hormone concentrations. Collectively, concentrations of inhibin-A and -B were aligned with physiological events in healthy mares, though more pronounced cyclic changes were seen with inhibin-A. Inhibin-B concentrations were significantly associated with GCTs (P < 0.01), inhibin-A concentrations were not. While both inhibin-A and -B concentrations track physiological events such as cyclic follicular activity, only inhibin-B concentrations effectively signal ovarian neoplasia in mares.

Augmentation of Water Resources Potential and Cropping Intensification Through Watershed Programs.

This paper presents the biophysical impact of various interventions made under watershed development programs, in terms of the creation of additional water resources, and resultant changes in land use and cropping patterns in the Bundelkhand region of Madhya Pradesh State, India. Both primary and secondary data gathered from randomly selected watersheds and their corresponding control villages were used in this study. Analysis revealed that emphasis was given primarily to the creation of water resources potential during implementation of the programs, which led to augmentation of surface and groundwater availability for both irrigation and non-agricultural purposes. In addition, other land based interventions for soil and moisture conservation, plantation activities, and so forth, were taken up on both arable and nonarable land, which helped to improve land slope and land use, cropping pattern, agricultural productivity, and vegetation cover.

A dosimetric comparison between three-dimensional conformal radiation therapy and intensity-modulated radiation therapy in the treatment of posterior fossa boost in medulloblastoma.

AIMS: To compare three-dimensional conformal radiation therapy (3DCRT) and intensity-modulated radiation therapy (IMRT) in posterior fossa (PF) boost in children with medulloblastoma (MB); dosimetrically evaluating and comparing both techniques with regard to target coverage and doses to organs at risk. SETTINGS AND DESIGN: Structured. SUBJECTS AND METHODS: Seven previously irradiated patients of MB were retrieved and re-planned with both 3DCRT and IMRT techniques. Dosimetric comparison was done by performing two plans for the PF boost for the same patient. Prescription dose and normal tissue constraints were identical for both plans. STATISTICAL ANALYSIS USED: SPSS, version 19, statistical software package was used. For quantitative data, paired t-test was applied to calculate the difference between two means. RESULTS: Mean values of planning target volume (PTV); PTV95% and PTV5% in IMRT were 97.19% and 106.07% and for 3DCRT were 96.57% and 106.33%, respectively. The dose homogeneity was better in IMRT (1.091) as compared to 3DCRT (1.100), but was not statistically significant (P = 0.341). Conformity index was comparable in both the plans, i.e., 3DCRT (0.979) and IMRT (0.976) with P = 0.819. IMRT plan provided reduced mean dose to cochlea relative to the 3DCRT plans with P = 0.032 for the right cochlea and 0.020 for the left cochlea. IMRT showed no advantage over 3DCRT in sparing the anterior cranial structures where mean doses to the right and left lens were 0.61 Gy and 0.56 Gy for IMRT and 0.16 Gy and 0.09 Gy for 3DCRT, respectively. CONCLUSIONS: IMRT technique was able to improve homogeneity index, spare the cochleae, but 3DCRT plans were superior in sparing anterior cranial structures without compromising the dose to PF.

Proteolytic processing of anti-Müllerian hormone differs between human fetal testes and adult ovaries.

From early embryonic life, anti-Müllerian hormone (AMH) is produced by Sertoli cells and is essential for male sex differentiation. In females, AMH is produced by immature granulosa cells (GCs) but a definitive function in females is uncertain. We have assessed the cellular localization and specificity of a panel of five novel high-affinity AMH monoclonal antibodies. Two recognize the mature C-terminal form of AMH, whereas three recognize the active pro-mature form of AMH in human tissue. The antibodies were tested on fetal male testicular and mesonephric tissue aged 8-19 weeks post conception (pc), fetal male serum aged 16-26 weeks pc and human immature GCs by immunofluorescence, immunohistochemistry, ELISA and western blotting. The active pro-mature forms of AMH were expressed in both Sertoli cells from human fetal testis and human immature GCs. In contrast, the mature C-terminal form of AMH was hardly detected in Sertoli cells, but was readily detected in GCs. This particular form was also located to the nucleus in GCs, whereas the other investigated AMH forms remained in the cytoplasm. Interestingly, the distribution of the AMH forms in the fetal serum of boys showed that the fraction of inactive precursor AMH only accounted for 4.5% ± 0.6 (mean ± SD) of the total AMH measured, and the remaining AMH was the active pro-mature form. Furthermore, western blot analysis demonstrated a number of previously unrecognized molecular forms of AMH. The present findings suggest that processing of AMH is a tightly regulated process, which is likely to be important for the function of AMH and which differs between the two sexes.

Trade-off of ovarian lipids and total body lipids for fecundity and starvation resistance in tropical populations of Drosophila melanogaster.

In Drosophila melanogaster, clines of starvation resistance along a latitudinal gradient (south to north) have been reported in India, which matched with their cline for total body lipids (TL ). Nevertheless, producing too many reserves is likely to be costly and a trade-off might exist with life-history traits. Previous studies on starvation resistance and life-history traits of D. melanogaster have mainly focused on quantification of total body lipids, instead of separating ovarian lipids from total body lipids. In the present study, we have quantified absolute ovarian lipids (OL ) versus absolute body lipids excluding ovarian lipids (BL ) and examined associations with fecundity as well as starvation resistance in two latitudinal populations (8.34 vs. 32.43°N) of D. melanogaster. Firstly, we observed a trade-off between BL and OL that matched the trade-off of starvation resistance, longevity versus fecundity and development time in latitudinal populations of D. melanogaster. Southern populations had higher starvation resistance, more BL and lesser OL, whereas northern populations had enhanced fecundity, OL and lesser BL . Secondly, within population, starvation resistance also correlated with BL , and fecundity with OL . However, there was no correlation between starvation resistance and OL . Moreover, there was utilization of BL and nonutilization of OL under starvation stress. Therefore, resources invested for fecundity in the form of OL were independent of evolved starvation resistance in D. melanogaster. Our results suggest that a common pool of energy storage compounds (lipids) are allocated differentially between fecundity and starvation resistance and are consistent with Y-model of resource allocation.

Effect of parental training in managing the behavioral problems of early childhood.

OBJECTIVE: To examine the effect of parental training on disturbed behavior of early childhood cases presented to the pediatricians. METHODS: The patients who reported in pediatric OPD of the Himalayan Institute of Medical Sciences, Dehradun, with complaints of low learning, poor memory, vertigo, speech problem, stress, headache, depression, adjustment problems, aggression, and hostile behavior were included in the study. Children aged 3 through 6 (N = 60), were screened through PBQ (Preschool Behavior Questionnaire), DST (developmental screening Test), and Vineland Social Maturity Scale (VSMS). Children included in the study had an average range of developmental quotient 85-90 (mean DQ = 87.5). Range of social quotient was 40-45 (mean SQ = 42.5). Twenty four fortnightly sessions of 'parental training' using the model of 'Mindful Parenting' were conducted. Single group t test method was applied in order to see the difference in mean of pre and post assessment of PBQ. RESULTS: After concluding parental training (after 24 sessions), mean difference of total disturbed behavior was found to be significant (t value: 5.31 > .05) Similarly, the mean difference of hostile/aggressive behavior (t value: 10.2 > .05), anxious behavior (t value: 18.5 > .05), and hyperactive/distractible behavior (t value: 1.97 > .05) were found to be significant. CONCLUSIONS: These results provide some evidence in favor of parental training in managing behavioral problems occurring in early childhood. Instead of putting the child immediately on medication, parents can get training and prepare a plan to understand and make a change in child's behavior leading to better health.

Febrile seizures.

Febrile seizures are the most common form of childhood seizures occurring in 2 to 5% of children in the United States. Most febrile seizures are considered simple, although those with focal onset, prolonged duration or that occur more than once within the same febrile illness are considered complex. Risk factors for a first febrile seizure, recurrence of febrile seizures and development of future epilepsy are identifiable and varied. Children with febrile seizures encounter little risk of mortality and morbidity and have no association with any detectable brain damage. Recurrence is possible, but only a small minority will go on to develop epilepsy. Although anti-epileptic drugs can prevent recurrent febrile seizures, they do not alter the risk of subsequent epilepsy. This has led to a changing view of how we approach the treatment of these common and largely benign seizures.
