Three-Dimensional Anorectal Manometry Enhances Diagnostic Gain by Detecting Sphincter Defects and Puborectalis Pressure

Digestive Diseases and Sciences - Constipation and fecal incontinence (FI) are common and are often evaluated with anorectal manometry. Three-dimensional high-resolution anorectal manometry (HRAM)...     

The Window Matters: A Systematic Review of Time Restricted Eating Strategies in Relation to Cortisol and Melatonin Secretion

Time-Restricted Eating is an eating pattern based on the circadian rhythm which limits daily food intake (usually to ≤12 h/day), unique in that no overt restriction is imposed on the quality, nor quantity, of food intake. This paper aimed to examine the effects of two patterns of TRE, traditional TRE, and Ramadan fasting, on two markers of circadian rhythm, cortisol and melatonin. PubMed and Web of Science were searched up to December 2020 for studies examining the effects of time restricted eating on cortisol and melatonin. Fourteen studies met our inclusion criteria. All Ramadan papers found statistically significant decrease in melatonin (p < 0.05) during Ramadan. Two out of the three Ramadan papers noted an abolishing of the circadian rhythm of cortisol (p < 0.05). The non-Ramadan TRE papers did not examine melatonin, and cortisol changes were mixed. In studies comparing TRE to control diets, Stratton et al. found increased cortisol levels in the non-TRE fasting group (p = 0.0018) and McAllister et al. noted no difference. Dinner-skipping resulted in significantly reduced evening cortisol and non-significantly raised morning cortisol. Conversely, breakfast skipping resulted in significantly reduced morning cortisol. This blunting indicates a dysfunctional HPA axis, and may be associated with poor cardio-metabolic outcomes. There is a paucity of research examining the effects of TRE on cortisol and melatonin. The contrasting effect of dinner and breakfast-skipping should be further examined to ascertain whether timing the feeding window indeed has an impact on circadian rhythmicity.     

Elevated level of prostate specific antigen among prostate cancer patients and high prevalence in the Gangetic zone of Bihar, India

Prostate cancer (CaP) is a common reproductive cancer among men. This study was conducted to correlate the cancer incidence with Gangetic zone and to correlate the tumor marker prostate specific antigen (PSA) level in serum with different age groups and stage of malignancy. Patients suffering from CaP in the pathology unit of Mahavir Cancer Sansthan (Hospital and Research Centre), Patna, Bihar, India were studied from June 2009 to May 2010. PSA level in the serum of CaP patients was estimated by ELISA method. CaP incidence was highly recorded in Gangetic zone than the non-Gangetic zone. Maximum patients were in the 56 - 75 years age group with a marked predominance. Results of PSA examination showed that serum PSA level was not correlating with the age of patient and stage of malignancy. Significantly, elevated level of more than 10 ng/ml of PSA was recorded among the studied cancer patients. In this study, it is concluded that Gangetic zone habitat have high risk of CaP and elevated level of PSA was marked in Bihar, India.

A Feasibility Study on Recruiting Fathers of Young Children to Examine the Impact of Paternal Depression on Child Development

Fathers are underrepresented in research on mental health and child outcome.We tested a range of methods of recruitment of fathers to establish feasibility and recruitment rates to obtain a sample for a study on paternal depression and child development. The study took place in North London. Fathers of children aged 6 years and under were approached via: general practice surgeries by post and by face-to-face contact with attendees; child health surveillance clinics face-to-face or via their partners and via hospital postnatal wards face-to-face or by post. Researcher time and associated costs were monitored for each method, and symptoms of depression and anxiety measured using the Hospital Anxiety and Depression Scale (HADS). Face-to-face recruitment of fathers on the postnatal ward generated the highest return rate of HADS (28/37; 76%), followed by postal recruitment through general practice (41%;124/303). Lower response rates were observed with postal recruitment via postnatal wards (31%), recruitment in child health surveillance clinics (20%) and approaching attendees in general practice (16%). Twelve percent (23/194) and 30% (58/194) of fathers respectively reported depression and anxiety above the cut-off for case-definition. Costs were calculated on pro-rata researcher time. Costs of recruiting one participant ranged from £ 3 (general practice postal) to £ 11.75 (child health surveillance clinics), however the general practice attender method was disproportionately expensive (£ 52.50). This feasibility study shows that it is possible to recruit fathers to mental health studies and provides clear guidance on planning, costing and the expected levels of recruitment for future studies on fathers of young children.     

Analysis of phytochemical profile of Terminalia arjuna bark extract with antioxidative and antimicrobial properties

Objective

To investigate phytochemical screening, antimicrobial activity and qualitative thin layer chromatographic separation of flavonoid components, antioxidant activity and total flavonoid compound of Terminalia arjuna.

Methods

For phytochemical screening, some common and available standard tests were done. Antimicrobial bioassay was done through agar well diffusion method. Detection of antioxidant activity and flavonoid compounds were done through thin layer chromatography. Total antioxidant activity was measured by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) in colorimetric method. Aluminum chloride colorimetric method was used for total flavonoid determination.

Results

Phytochemical screening showed the active compounds presence in high concentration, such as phytosterol, lactones, flavonoids, phenolic compounds and tannins and glycosides. The antimicrobial activity of extract showed that greater inhibition zone against Gram negative bacteria than Gram positive bacteria. This methanolic extract showed a promising antioxidant activity, as absorption of DPPH redicles decreased in DPPH free radical scavenging assay. Flavonoids components having antioxidant property present in the methanol extract at a level of 199.00 mg quercetin equivalent/g of dried methanol extract in colorimetric method.

Conclusions

The Terminalia arjuna bark extract revealed the presence of bio-active constituents which are known to exhibit medicinal as well as physiological activities.
