Prostate cancer risk stratification using magnetic resonance imaging-ultrasound fusion vs systematic prostate biopsy.

BACKGROUND: Image-guided approaches improve the diagnostic yield of prostate biopsy and frequently modify estimates of clinical risk. To better understand the impact of magnetic resonance imaging-ultrasound fusion targeted biopsy (MRF-TB) on risk assessment, we compared the distribution of National Comprehensive Cancer Network (NCCN) risk groupings, as calculated from MRF-TB vs systematic biopsy alone. METHODS: We performed a retrospective analysis of 713 patients who underwent MRF-TB from January 2017 to July 2021. The primary study objective was to compare the distribution of National Comprehensive Cancer Network risk groupings obtained using MRF-TB (systematic + targeted) vs systematic biopsy. RESULTS: Systematic biopsy alone classified 10% of samples as very low risk and 18.7% of samples as low risk, while MRF-TB classified 10.5% of samples as very low risk and 16.1% of samples as low risk. Among patients with benign findings, low-risk disease, and favorable/intermediate-risk disease on systematic biopsy alone, 4.6% of biopsies were reclassified as high risk or very high risk on MRF-TB. Of 207 patients choosing active surveillance, 64 (31%), 91 (44%), 42 (20.2%), and 10 (4.8%) patients were classified as having very low-risk, low-risk, and favorable/intermediate-risk and unfavorable/intermediate-risk criteria, respectively. When using systematic biopsy alone, 204 patients (28.7%) were classified as having either very low-risk and low-risk disease per NCCN guidelines, while 190 men (26.6%) received this classification when using MRF-TB. CONCLUSION: The addition of MRF-TB to systematic biopsy may change eligibility for active surveillance in only a small proportion of patients with prostate cancer. Our findings support the need for routine use of quantitative risk assessment over risk groupings to promote more nuanced decision making for localized cancer.

Hearing the voices of adolescents: Evaluating the quality of care for young adults with chronic illnesses in the UAE.

BACKGROUND: Quality care for adolescents and young adults with chronic illnesses has been under-explored in the United Arab Emirates (UAE) and internationally, especially from patients' perspectives. Most available international studies focused on quality of life and the transition to adulthood rather than service quality. AIM: This research assesses care quality for adolescents with chronic illnesses in the UAE, aiming to understand their perspectives, appraise current practices, and identify service gaps. METHODS: A cross-sectional survey employed a validated questionnaire examining 33 essential care components. Participants comprised 576 adolescents and young adults with chronic conditions from five UAE Emirates. RESULTS: Participant's reports indicated that none of the 33 care elements were received consistently. Most participants (80.6%) reported crucial care aspects were absent, and across most investigated items, 19.4%-46.5% of participants reported receiving the services they were supposed to receive only some or many of the times, indicating significant areas for improvement. CONCLUSIONS: Findings demonstrate significant care quality gaps for UAE's adolescents and young adults with chronic illnesses. These may critically affect their ability to manage their conditions and ensure holistic growth. These insights can guide healthcare enhancements tailored to this demographic. PRACTICE IMPLICATIONS: There is an urgency for enhanced patient-centered care in UAE healthcare, emphasizing clinicians' roles in supporting adolescents with chronic illnesses, especially during transitions. Healthcare managers should prioritize standardized care policies, improved communication, and training that emphasizes consistent patient feedback and transition readiness. Further research into care gaps and tailored interventions within the region's distinct sociocultural setting is essential.

The impact of cultural healthcare practices on Children's health in the United Arab Emirates: a qualitative study of traditional remedies and implications.

Aim: This qualitative study investigates the impact of cultural practices on children's health in the United Arab Emirates (UAE) by examining the use of traditional remedies and home treatments by mothers. Methods: Twenty-five participants, all mothers who had employed traditional treatments or home remedies for their children during periods of illness, were included in the study. The participants represented a diverse range of educational backgrounds, from school diploma holders to university degree graduates, with ages spanning from 20 to 50 years. Hailing from different Arabic countries and cultural subgroups, the majority of participating mothers were from the UAE. Results: Through in-depth interviews, three major themes emerged from the participants' experiences. Firstly, a strong connection between culture, religion, and healthcare practices was evident. Many mothers opted for cultural remedies as their first line of defense against illnesses due to the practices' strong foundations in their cultural heritage. Herbal remedies, Quranic healing, and other traditional methods were perceived to be both effective and spiritually comforting, reinforcing participants' sense of cultural identity. Secondly, participants highlighted unintended consequences of relying solely on traditional treatments. Some instances were reported where the use of ineffective remedies resulted in delays in seeking appropriate medical care for their children, potentially compromising their health. Additionally, certain misconceptions regarding the safety and efficacy of traditional remedies were identified, emphasizing the need for evidence-based healthcare education. Conclusion: This qualitative study sheds light on the intricate interplay between culture, traditional remedies, and children's health in the UAE. The incorporation of diverse participants from various Arabic countries and cultural subgroups enriches the study's applicability to broader Arabic cultures. By recognizing the significance of cultural healthcare practices and striking a balance with evidence-based care, healthcare providers can create a more inclusive and effective healthcare environment for children in the UAE. Future research should explore diverse samples and develop targeted interventions to further advance cultural awareness and understanding in healthcare practices.

Habit-reversal training: a psychotherapeutic approach in treating body-focused repetitive behaviour disorders.

Body-focused repetitive behaviours (BFRBs) are recurrent, compulsive, destructive behaviours directed towards the body. Although studies have demonstrated a 12-14% prevalence rate, researchers found that dermatologists and psychiatrists show a lack of knowledge regarding psychodermatology resources and information about BFRB disorders (BFRBDs) such as trichotillomania (TTM). There is limited research about treatments including ones investigating the clinical applications of various self-help training such as decoupling (DC) and DC in sensu (DC-is) as well as about habit-reversal training (HRT). HRT is a five-component behavioural intervention that aims to develop a competing response to a specific unwanted behaviour. Studies have found substantial support for HRT's efficacy in treating a variety of maladaptive repetitive behaviours including onychotillomania, TTM, skin-picking disorder and chronic cheek biting. Additionally, many psychotherapies can augmented HRT. Psychotherapies include acceptance and commitment therapy, dialectical behaviour therapy, psychodynamic psychotherapy, mindfulness mediation and the cognitive psychophysiological model. A recently investigated variant of HRT, DC-is, resulted in consistently satisfactory objective and subjective improvement for treating BFRBDs, and HRT showed good subjective but poor objective improvement compared with standard DC. HRT and HRT variants are effective therapeutic treatments for BFRBDs; however, further randomized double-blinded and placebo-controlled trials are required to examine HRT's therapeutic profile.

Ejaculatory Preserving Holmium Laser Enucleation of the Median Lobe: Preserving Sexual Function While Improving Urinary Outcomes.

OBJECTIVE: To evaluate perioperative outcomes related to sexual and urinary function in patients who underwent a holmium laser enucleation of the prostate (HoLEP) with selective laser enucleation of the median lobe. MATERIALS AND METHODS: We retrospectively reviewed the first 450 HoLEP cases by a single surgeon from April 2019 to March 2022. Fifty-five patients with intravesical-prostatic protrusion or high bladder neck without obstructing lateral lobes underwent selective enucleation of the median lobe of the prostate. Patients were asked to comment on whether they had retrograde ejaculation during their follow-up appointment. Urinary function was assessed using the American Urological Association Symptom Score and subjective evaluation of urinary incontinence. RESULTS: Median age of the cohort was 65 years (range: 44-91). Compared to preoperative, there was significant improvement in mean postoperative American Urological Association Symptom Score (22.5 vs 6.9, P < .001), mean postoperative quality of life scores (4 vs 1.2, P < .001), and mean postoperative post void residual volumes (244.1 vs 69.3 cc, P < .001). No patients reported stress urinary incontinence. Of the 55 patients who underwent selective enucleation of the median lobe, 40 were sexually active. Of those men, 35 reported normal ejaculation, 3 had retrograde ejaculation that was unchanged from pre-op, and 2 had new ejaculatory dysfunction. CONCLUSION: In this case series of selective laser enucleation of the median lobe, urinary function significantly improved in short-term follow-up with preservation of ejaculation in approximately 90% of men.

Gestational and childhood urinary iodine concentrations and children's cognitive function in a longitudinal mother-child cohort in rural Bangladesh.

BACKGROUND: Severe iodine deficiency adversely affects neurodevelopment; however, evidence regarding the association of non-severe deficiency and child cognitive functioning is inconclusive. METHODS: This prospective mother-child cohort study was nested in a population-based nutritional supplementation trial in Bangladesh (Maternal and Infant Nutrition Interventions in Matlab [MINIMat]). Participants with data on cognitive abilities at 5 and 10 years of age (n = 1530) and at least one measurement of urinary iodine concentration (UIC) (gestational week 8, 5, and 10 years) were selected. Cognitive abilities were assessed using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III) and Wechsler Intelligence Scale for Children (WISC-IV). UICs were measured with inductively coupled plasma mass spectrometry and thereafter adjusted for specific gravity. RESULTS: Median UICs in our population: (282 µg/L [pregnancy]; 406 µg/L [5 years]; 294 µg/L [10 years]) indicated that iodine intake corresponded to above 'adequate' or even 'excessive', according to the WHO classification. Maternal 'UIC <150 µg/L' was associated with lower full-scale and verbal scores at 5 and 10 years, although the associations were weakened in the fully adjusted models. A tendency of decreased verbal scores was also observed for maternal 'UIC ≥500 µg/L' but not for the corresponding child iodine category (≥300 µg/L). Child 'UIC <100 µg/L' was associated with lower processing speed (B=-3.1, 95% CI [-6.2, -0.1]; P-value = 0.041) compared with the reference group (100 µg/L≤ UIC <300 µg/L). CONCLUSIONS: Current findings add to the growing evidence of a causal association of early-life iodine intake with cognitive development, indicating that low iodine intake during childhood is associated with reduced processing speed and non-optimal gestational iodine intake is weakly associated with slightly poorer verbal development outcomes.

Traditional, religious, and cultural perspectives on mental illness: a qualitative study on causal beliefs and treatment use.

PURPOSE: Limited information is known from studies regarding traditional, religious, and cultural perspectives on mental illness and the use of traditional and alternative therapies by mentally ill people in Indonesia. This study explored traditional, religious, and cultural beliefs about causes of mental illness and the use of traditional/alternative treatments for mentally ill patients. METHOD: We adopted a qualitative content analysis method as proposed by Schreier. This study was conducted at a mental Hospital in Indonesia. We interviewed 15 nurses and 15 patients. Data were analysed using qualitative content analysis method. RESULTS: Five discrete but interrelated themes emerged: 1) Possessed illness and belief in supernatural forces; 2) Sinful or cursed illness; 3) Witchcraft or human-made illness; 4) traditional/alternative treatments; and 5) Barriers to treatment of mental illness. CONCLUSION: Traditional/alternative treatments play an important role in meeting the need for mental health treatment. The findings are relevant for mental health nurses who provide direct to their patients, and for other areas of mental health practice. We also found a lack of knowledge about the causes of mental illness among patients and families. Education should be at the heart of mental health promotion to raise the level of mental health literacy in Indonesia.

Ancient wisdom of ayurveda vis-à-vis contemporary aspect of materiovigilance.

Materiovigilance is regulatory system to study and follow incidents that might result from using medical devices. To trail the occurrence of untoward effects associated with medical devices as well as to document and prevent their recurrence; the Indian Pharmacopeia Commission initiated Materiovigilance program in India (MvPI) in 2015. Classical texts of Ayurveda include substantial description of devices intended for various therapeutic purposes such as Panchakarm (penta-bio purification procedures), Surgeries and for management of gynecological conditions etc. The implemented program of Materiovigilance does not include Ayurveda devices and thus there is need for documentation, systematic classification of Ayurveda devices and development of Ayurveda Materiovigilance (AMv). In this review, relevant information from classical texts of Ayurveda, latest published information related to Materiovigilance and information of medical devices from classical texts of Ayurveda has been scrutinized along with systematic correlation and applied interpretation of the collected data. It is observed that Materiovigilance has been well documented in Ayurveda in context of twenty six surgical and diagnostic devices; eleven mostly utilized pharmaceutical instruments five Panchakarma instruments and five home devices. For regulation of quality of Ayurveda medical devices, their manufacturing, standard utilization, reporting and prevention of medical device associated errors; it is the need of hour to create and implement regulation in the form of AMv. The Ayurveda literature highlights that the ancient seers of Ayurveda were well aware regarding Materiovigilance in their own way. However in view of modern era and mainstreaming of Ayurveda heritage, critical revision, updating, systematically categorization of Ayurveda devices, development and implementation of AMv regulation is the need of hour.

Association between maternal plasma ferritin level and infants' size at birth: a prospective cohort study in rural Bangladesh.

Background: Iron supplementation in pregnancy is recommended by the WHO to prevent a major public health problem, namely, maternal iron deficiency and its consequences. There are gaps in the existing evidence regarding maternal and neonatal benefits and harms of universal iron supplementation. Objective: To evaluate the association between maternal iron status during pregnancy and infant size at birth (birth weight and length). Method: This present prospective cohort study was nested in a food and micronutrient supplementation trial conducted in Matlab (MINIMat study), rural Bangladesh. We randomly selected 573 women recruited into the MINIMat study from January - December 2002 who delivered singletons with available birth anthropometric information. The plasma ferritin of each mother was measured at gestational week 14 (GW14; before the start of micronutrient supplementation) and at week 30 (GW30). Results: Multivariable linear regression revealed no association between plasma ferritin at GW14 and birth weight. However, newborns of women in the highest tertile of plasma ferritin at GW30 (median = 29 µg/L) had on average a 93-gm lower birth weight (95% CI: -172, - 14; p = 0.021) than the newborns of womehemoglobin (Hb) synthesisn in the lowest tertile (median = 8 µg/L). Logistic regression showed that odds of low birth weight were approximately two times higher [odds ratio (OR) = 2.27; 95% CI: 1.40, 3.67] among those with mothers in the highest ferritin tertile than in the lowest tertile at GW30. No association was found between maternal plasma ferritin and birth length. Conclusion: We observed an inverse association between high plasma ferritin in the last trimester (GW30) and birth weight but not birth length. The results suggested that elevated plasma ferritin in pregnancy could have an untoward effect on birth weight.

Lead and cadmium exposure induces male reproductive dysfunction by modulating the expression profiles of apoptotic and survival signal proteins in tea-garden workers.

The aim of this study was to evaluate the impact of Lead (Pb) and Cadmium (Cd) exposure at the molecular level on the reproductive status of tea garden workers in North-East India. Using semen samples, we experimentally determined sperm analysis as well as oxidative stress parameters in all samples and evaluated the expression levels of apoptotic and cell survival proteins [p53, phospho-Akt, nuclear factor-κB (NF-κB, p50 subunit) and B cell lymphoma 2 (Bcl2)]. Our data revealed significant differences in the average heavy metal concentrations and various semen analysis profile between the infertile and normal groups. Increasing Pb and Cd concentrations in semen samples of patients showed positive associations with increasing number of multiple defects in sperm and the level of seminal oxidative stress markers in the high Pb and Cd concentration groups. These groups also exhibited positive correlations between high metal concentrations and the average p53 expression levels, but negative correlations with the mean p-Akt cascade protein levels in sperm cells. In the low Pb and Cd concentrations groups, we also observed reverse mean range and correlation patterns. Therefore, our findings may suggest that graded levels of metal exposure significantly influence the relative fluctuation in the levels of p53 and Akt cascade proteins in the sperm cells of infertile subjects. Furthermore, this may be a regulating factor of sperm cell fate, in turn, determining the fertility outcome of the men working in the tea gardens.

Influence of fermentation on antioxidant and hypolipidemic properties of maifanite mineral water-cultured common buckwheat sprouts.

Buckwheat sprouts (BS) becomes popular due to its' health-promoting properties as food product. The effects of fermentation with Saccharomyces cerevisiae and Lactobacillus plantarum on antioxidant and hypolipidemic activities as well as functional composition in common BS cultivated in maifanite mineral water were investigated here. DPPH and ·OH results showed higher antioxidant potential in fermented BS compared to unfermented BS, due to the higher rutin, orientin, isoorientin, vitexin, isovitexin, and total phenolic and flavonoid contents. The S. cerevisiae-fermented BS also exhibited 113% and 110% higher DPPH and ·OH scavenging activities than the L. plantarum-fermented BS, respectively. In hyperlipidemic mice, blood lipid parameters were improved as dose-dependent manner when supplemented the food with S. cerevisiae-fermented BS. Fermented BS also restored liver antioxidant levels significantly. The fermented BS had greater effect on different parameters than those of unfermented BS. Therefore, fermentation is a valuable method to enhance the bioactive potential of BS.

[The MINIMat study in Bangladesh: International research collaboration and research training with a perspective from foetus to future health]. / Från foster till framtida hälsa - MINIMat-studien i Bangladesh har halverat dödligheten hos spädbarn och gett bättre tillväxt och metabola markörer.

In South Asia, maternal and child undernutrition is common with consequences for short- and long-term health. In the MINIMat trial (Maternal and Infant Nutrition Interventions in Matlab) in Bangladesh 4436 pregnant women were allocated to early or later start of food supplements and different micronutrient alternatives. Children of mothers who received food supplementation from week 9 combined with multiple micronutrients showed a halved infant mortality rate. The early initiation of prenatal food supplementation reduced the risk of stunting up to five years and was associated with more favourable metabolic markers. The MINIMat study is run by icddr,b in Bangladesh and Uppsala University in collaboration with seven other universities. Twenty Ph.D. students have so far defended their theses and more than 100 scientific papers have been published.

Dual direction CRISPR transcriptional regulation screening uncovers gene networks driving drug resistance.

Pooled CRISPR-Cas9 knock out screens provide a valuable addition to the methods available for novel drug target identification and validation. However, where gene editing is targeted to amplified loci, the resulting multiple DNA cleavage events can be a cause of false positive hit identification. The generation of nuclease deficient versions of Cas9 has enabled the development of two additional techniques - CRISPR interference (CRISPRi) and CRISPR activation (CRISPRa) - that enable the repression or overexpression, respectively, of target genes. Here we report the first direct combination of all three approaches (CRISPRko, CRISPRi and CRISPRa) in the context of genome-wide screens to identify components that influence resistance and sensitivity to the BRAF inhibitor, vemurafenib. The pairing of both loss- and gain-of-function datasets reveals complex gene networks which control drug response and illustrates how such data can add substantial confidence to target identification and validation analyses.

Vitamin B12 supplementation during pregnancy and postpartum improves B12 status of both mothers and infants but vaccine response in mothers only: a randomized clinical trial in Bangladesh.

PURPOSE: Poor vitamin B12 (B12) status is associated with adverse outcomes in pregnancy and infancy. Little is known about effects of B12 supplementation on immune function. The present study aimed to evaluate effects of pre- and postnatal B12 supplementation on biomarkers of B12 status and vaccine-specific responses in mothers and infants. METHOD: In a blinded, placebo-controlled trial, Bangladeshi women (n = 68, age 18-35 years, hemoglobin <110 g/L, 11-14 weeks pregnant) were randomized to receive 250 µg/day B12 or a placebo throughout pregnancy and 3-month postpartum along with 60 mg iron + 400 µg folate. Women were immunized with pandemic influenza A (H1N1) vaccine at 26- to 28-week gestation. Blood from mothers (baseline, 72-h post-delivery, 3-month postpartum), newborns and infants (3-month) was analyzed for hemoglobin, B12, methylmalonic acid (MMA), total homocysteine (tHcy), ferritin and serum transferrin receptor, C-reactive protein (CRP) and alpha-1-acid glycoprotein (AGP). Vitamin B12 was also assessed in breast milk. H1N1-specific antibodies were determined in plasma and colostrum/breast milk. RESULTS: At baseline, 26% women were B12 deficient (<150 pmol/L), 40% had marginal status (150-220 pmol/L), 43% had elevated MMA (>271 nmol/L), and 31% had elevated tHcy (>10 µmol/L). Supplementation increased B12 in plasma, colostrums and breast milk (p < 0.05) and lowered MMA in neonates, mothers and infants at 3 months (p < 0.05). B12 supplementation significantly increased H1N1-specific IgA responses in plasma and colostrums in mothers and reduced proportion of infants with elevated AGP and CRP compared with placebo. CONCLUSION: Supplementation with 250 µg/day B12 during pregnancy and lactation substantially improved maternal, infant and breast milk B12 status. Maternal supplementation improved H1N1 vaccine-specific responses in mothers only and may alleviate inflammatory responses in infants.

Determinants and pattern of care seeking for preterm newborns in a rural Bangladeshi cohort.

BACKGROUND: Despite the increased burden of preterm birth and its complications, the dearth of care seeking data for preterm newborns remains a significant knowledge gap. Among preterm babies in rural Bangladesh, we examined: 1) determinants and patterns of care seeking, and 2) risk analysis for care-seeking from qualified and unqualified providers. METHOD: Trained community health workers collected data prospectively from 27,460 mother-liveborn baby pairs, including 6,090 preterm babies, between June 2007 and September 2009. Statistical analyses included binomial and multinomial logistic regressions. RESULTS: Only one-fifth (19.7%) of preterm newborns were taken to seek either preventive or curative health care. Among care-seeker preterm newborns, preferred providers included homeopathic practitioners (50.0%), and less than a third (30.9%) sought care from qualified providers. Care-seeking from either unqualified or qualified providers was significantly lower for female preterm babies, compared to male babies [Relative Risk Ratio (RRR) for unqualified care: 0.68; 95% Confidence Interval (CI): 0.58, 0.80; RRR for qualified care: 0.52; 95% CI: 0.41, 0.66]. Among preterm babies, care-seeking was significantly higher among caregivers who recognized symptoms of illness [RR: 2.14; 95% CI: 1.93, 2.38] or signs of local infection (RR: 2.53; 95% CI: 2.23, 2.87), had a history of child death [RR: 1.21; 95% CI: 1.07, 1.37], any antenatal care (ANC) visit [RR: 1.41; 95% CI: 1.25, 1.59]. Birth preparedness (RRR: 1.24; 95% CI: 1.09, 1.68) and any ANC visit (RRR: 1.73; 95% CI: 1.50, 2.49) were also associated with increased likelihood of care seeking for preterm babies from qualified providers. CONCLUSION: To improve care seeking practices for preterm babies and referral of sick newborns to qualified providers/facilities, we recommend: 1) involving community-preferred health care providers in community-based health education and awareness raising programs; 2) integrating postnatal care seeking messages into antenatal counselling; and 3) further research on care seeking practices for preterm babies.

Incidence and risk factors of preterm birth in a rural Bangladeshi cohort.

BACKGROUND: Globally, about 15 million neonates are born preterm and about 85% of global preterm birth occurs in Asia and Africa regions. We aimed to estimate the incidence and risk factors for preterm birth in a rural Bangladeshi cohort. METHODS: Between June 2007 and September 2009, community health workers prospectively collected data from 32,126 mother-live-born baby pairs on household socio-demographic status, pregnancy history, antenatal care seeking and newborn gestational age determined by recall of date of last menstrual period. RESULTS: Among all live births, 22.3% were delivered prior to 37 weeks of gestation (i.e. preterm); of which 12.3% were born at 35-36 weeks of gestation (late preterm), 7.1% were born at 32-34 weeks (moderate preterm), and 2.9% were born at 28-31 weeks of gestation (very preterm). Overall, the majority of preterm births (55.1%) were late preterm. Risk of preterm birth was lower among women with primary or higher level of education (RR: 0.92; 95% CI: 0.88, 0.97), women who sought antenatal care at least once during the index pregnancy (RR: 0.86; 95% CI: 0.83, 0.90), and women who had completed all birth preparedness steps (RR: 0.32; 95% CI: 0.30, 0.34). In contrast, risk of preterm birth was higher among women with a history of child death (RR: 1.05; 95% CI: 1.01, 1.10), who had mid-upper arm circumference (MUAC) ≤250 mm, indicative of under nutrition (for women having MUAC <214 mm the risk was higher; RR: 1.26; 95% CI: 1.17, 1.35), who reported an antenatal complication (RR: 1.32; 95% CI: 1.14, 1.53), and who received iron-folic acid supplementation for 2-6 months during the index pregnancy (RR: 1.33; 95% CI: 1.24, 1.44). CONCLUSIONS: In resource poor settings with high burden of preterm birth, alike Bangladesh, preterm birth risk could be reduced by close monitoring and/or frequent follow-up of women with history of child death and antenatal complications, by encouraging women to seek antenatal care from qualified providers, to adopt birth preparedness planning and to maintain good nutritional status. Additional research is needed to further explore the associations of antenatal iron supplementation and maternal nutritional status on preterm birth.

Use of serotonergic antidepressants and St John's wort in older Australians: a population-based cohort study.

OBJECTIVE: The study investigated the use of serotonergic antidepressants (SSRIs: selective serotonin reuptake inhibitors; SNRIs: serotonin-norepinephrine reuptake inhibitors) and St John's wort in a large NSW-based community sample, and sought to identify a potentially dangerous concomitant use of these medications. METHODS: Cross-sectional data from 266,848 participants from the '45 and Up' study were used. The questionnaire captures self-reported treatment for depression or anxiety and antidepressant medications in the last four weeks. RESULTS: 5.8% of participants received treatment for depression or anxiety, with 4.7% taking an SSRI and 1.3% an SNRI. St John's wort was taken by 0.3% of the participants. Use of SSRIs and SNRIs was reported more frequently by females than males (respectively, 64.1% vs 35.9%, 66.9% vs 33.1%). The gender difference was even more pronounced for St John's wort (75.6% vs. 24.4%). Use of antidepressants decreased after the age of 65 years. One hundred and forty people reported concurrent use of an SSRI and an SNRI, and 11 people of an SSRI with St John's wort. CONCLUSIONS: Around 7% of the study population aged 45-65 years reported the use of SSRIs or SNRIs, decreasing to 5% above 70 years of age. It is of concern that some individuals used an SSRI concurrently with St John's wort.

Healthcare-seeking behaviour among the tribal people of Bangladesh: Can the current health system really meet their needs?

Despite the wealth of studies on health and healthcare-seeking behaviour among the Bengali population in Bangladesh, relatively few studies have focused specifically on the tribal groups in the country. This study aimed at exploring the context, reasons, and choices in patterns of healthcare-seeking behaviour of the hill tribal population of Bangladesh to present the obstacles and challenges faced in accessing healthcare provision in the tribal areas. Participatory tools and techniques, including focus-group discussions, in-depth interviews, and participant-observations, were used involving 218 men, women, adolescent boys, and girls belonging to nine different tribal communities in six districts. Data were transcribed and analyzed using the narrative analysis approach. The following four main findings emerged from the study, suggesting that the tribal communities may differ from the predominant Bengali population in their health needs and priorities: (a) Traditional healers are still very popular among the tribal population in Bangladesh; (b) Perceptions of the quality and manner of treatment and communication can override costs when it comes to provider-preference; (c) Gender and age play a role in making decisions in households in relation to health matters and treatment-seeking; and (d) Distinct differences exist among the tribal people concerning their knowledge on health, awareness, and treatment-seeking behaviour. The findings challenge the present service-delivery system that has largely been based on the needs and priorities of the plainland population. The present system needs to be reviewed carefully to include a broader approach that takes the sociocultural factors into account, if meaningful improvements are to be made in the health of the tribal people of Bangladesh.

Phytochemical analysis, cytotoxic activity and constituents-activity relationships of the leaves of Cinnamomum iners (Reinw. ex Blume-Lauraceae).

The leaves of Cinnamomum iners (Reinw. ex Blume-Lauraceae) have been refluxed successively with chloroform and alcohol to get chloroform extract and alcoholic extract. Both the extracts have been assayed for cytotoxicity against human colorectal tumour cells. The chloroform extract exhibited significant cytotoxicity with IC(50) 31 µg mL(-1) (p < 0.01). However, ethanol extract was found to be much less cytotoxic with IC(50) > 200 µg mL(-1). The chloroform extract has been further proceeded for chemical analysis by GC-TOFMS and 178 components were identified including acids, amines, amides, aldehydes, alcohols, esters, benzene derivatives, bicyclic compounds, terpenes, hydrocarbons, naphthalene derivatives, furan derivatives, azulenes, etc. Nine components representing 51.73% of the total chloroform extract were detected as major components. Caryophyllene (14.41%) and Eicosanoic acid ethyl ester (12.17%) are the most prominent components of the chloroform extract. ß-Caryophyllene (14.41%) as most abundant compound supports potent cytotoxicity as shown by chloroform extract.

A novel lupene-type triterpenic glucoside from the leaves of Clerodendrum inerme.

A new triterpenic glucoside, lup-1,5,20(29)-trien-3-O-beta-D-glucopyranoside (4), along with three known phytoconstituents: n-octacosane, friedelin and beta-amyrin, has been isolated from the leaves of Clerodendrum inerme (L.) Gaertn. (Verbenaceae). Structure elucidation was carried out on the basis of chemical and physical evidence (IR, 1H-NMR, 13C-NMR, DEPT and MS spectra). The alcoholic and aqueous extracts of the leaves of C. inerme showed significant antinociceptive activity in analgaesiometer tests.
