Predictors of self-medication with herbal remedies during pregnancy based on the theory of planned behavior in Kashan, Iran.

BACKGROUND: The incidence of application of medicinal herbs during pregnancy has increased significantly among women over the past years; however, the safety and efficacy of medicinal herbs during pregnancy are still unclear. The aim of the present study was to categorize the predictors of self-medication with herbal remedies during pregnancy based on the theory of planned behavior (TPB). METHODS: The present descriptive-analytical study was conducted on 300 pregnant women referred to Kashan health center to receive prenatal care services in 2020. The study participants were randomly selected using stratified random sampling with proportional allocation. The data collection tool was a two-part researcher made questionnaire. The first part of the questionnaire included demographic information, midwifery information, and questions related to women's awareness about herbal medicine. The second part of the questionnaire was designed based on the theory of planned behavior including attitudes, perceived behavioral control, subjective norms, intention, and behavior performance. Data were analyzed using descriptive statistics, regression analysis, and SPSS version 18.0. RESULTS: The mean age of participants was 28. 7±5.4 years (range, 15-45 years), the majority were housewives (88.3%) and had secondary education (39.3%). A total of 164 women (57. 1%) used medicinal herbs during pregnancy. The individual's attitude towards herbal medicines consumption, subjective norm, and perceived behavioral control was correlated with behavioral intention (P < 0.05). Similarly, subjective norms were the most predictor of using herbal medicine among pregnant women (P < 0.05). CONCLUSION: The findings revealed that more than 50 % of pregnant women used medicinal herbs during pregnancy. The present study showed that the individual's attitude towards herbal medicines consumption, subjective norm, and perceived behavioral control was correlated with intention of herbal medicine use among pregnant women. Likewise, subjective norms were the most predictor of herbal medicine use among pregnant women. The TPB should be addressed in planning health education programs and modifying health behaviors, including self-medication, especially during pregnancy.

Examination of Recreational and Spiritual Peyote Use Among American Indian Youth.

OBJECTIVE: Some American Indians legally use hallucinogenic substances as part of religious and spiritual ceremonies. Research to date has either failed to differentiate spiritual versus recreational use or has categorized hallucinogen use in an "other drug" or "illegal drug" category. This approach could contribute to ineffectual models of prevention and treatment intervention and limit understanding of hallucinogen use in American Indian cultures. METHOD: This study is a secondary data analysis of an ongoing epidemiologic and etiologic investigation of substance use among American Indian youth (N = 3,861). Two Firth logistic regression models were run with (a) spiritual peyote use and (b) recreational peyote use as the dependent variables, and grade, sex, 30-day alcohol use, 30-day marijuana use, religiosity, religious affiliation, and cultural identity as predictors, as well as a grade by sex interaction term. RESULTS: Grade, sex, religious affiliation, and the interaction term did not predict either recreational or spiritual peyote use. Thirty-day alcohol and marijuana use predicted both spiritual and recreational peyote use, but the effects were stronger for predicting recreational use. Religiosity and cultural identity predicted spiritual but not recreational use, such that American Indian youth who identified as more religious and identified more strongly with their culture were more likely to report using peyote for spiritual purposes. CONCLUSIONS: Our results suggest that current self-reported use of alcohol and/or marijuana by American Indian youth indicates an increased likelihood of using peyote. In addition, use of Firth logistic regression models proved feasible for analyzing rare events like peyote use.

Self-medication among the elderly in Iran: a content analysis study.

BACKGROUND: Self-medication is described as the use of drugs without a physician's prescription to treat self-recognized illness or symptoms, and an important health issue among the elderly. Despite the wide range of different definitions, recognizing all forms of self-medication among older adults, particularly, in developing countries, help healthcare professionals and providers to reduce harmful effects of self-medication. The purpose of this study is to describe the practice of self-medication and its related factors among elderly people in Iran based on the experiences of people who are involved in this phenomenon. METHODS: This qualitative study was conducted using content analysis. Purposive sampling was used to select the participants and continued until saturation. The participants were the elderly, their care-givers, physicians, and pharmacists. Data was collected using semi-structured interviews, and analysis was done using an inductive approach. The theory of planned behavior was used as a framework to explain the role of the emerged factors in the occurrence of self-medication behavior. RESULTS: Based on the expressed experiences of the participants, factors related to the practice of self- medication among the elderly in Iran fit in these 5 categories: "patient's attitudes towards disease, treatment, and physicians", "living with disease", "unfriendly environments", "enabling health system", and "influential others". CONCLUSIONS: Based on the results of this study, self-medication of the elderly in Iran has commonalities with many countries in regard to over-the-counter medications and complementary and alternative medicine; however, self-medication is also seen with drugs that require a prescription but can easily be obtained from pharmacies. Contributing factors, apart from the elderly themselves, include their families, caregivers, and social circle, the physical environment where they live, and the health system from which they receive services.

St John's wort (Hypericum perforatum)-induced psychosis: a case report.

BACKGROUND: St John's wort (Hypericum perforatum) has been known for centuries for its therapeutic properties and its efficacy as an antidepressant has been confirmed by a growing body of evidence. During the last two decades it has also come to prominence with a wider public, due to advertising efforts across Europe and United States of America. However, its availability without prescription, as an over-the-counter medication, raises some concern regarding its clinical management and unsupervised administration to individuals with psychopathological risks. To date, the evidence available regarding the administration of Hypericum in people with severe mental health problems is still meager and refers mainly to affective disorder spectrum or psychotic relapse in people with established diagnoses. To the best of our knowledge, this is the first report regarding the onset of psychotic features in a patient presenting with psychotic diathesis. CASE PRESENTATION: The case discussed in this report is a 25-year-old white man, not known to the psychiatric services, with a history of brief and self-remitting drug-induced psychosis and a positive family history of psychotic depression. He was admitted to hospital due to the onset of florid psychotic symptoms concomitant with self-administration of Hypericum perforatum. CONCLUSIONS: The aim of this report is to promote further systematic research, draw the attention of clinicians to the potential risks of Hypericum precipitating psychosis, and raise awareness among health professionals to investigate and caution their patients on the haphazard use of phytotherapeutics such as Hypericum.

Pharmaceutical Cognitive Enhancement in Greek University Students: Differences Between Users and Non-Users in Social Cognitive Variables, Burnout, and Engagement.

Pharmaceutical cognitive enhancement (PCE) represents the non-medical use of prescribed medication for the improvement of cognitive functioning and academic performance. Although there are some studies about PCE prevalence, it is less clear how users and non-users of PCE substances differ with respect to their positive and negative student experiences (e.g. academic burnout and engagement with studies) and in social cognitive variables that relate to decision-making and self-regulation of PCE use. The present study assessed whether students with different experiences of PCE substance use displayed differences in academic burnout, study engagement, and social cognitive variables relevant to PCE use. Three hundred and forty-seven university students (mean age (M) = 22.15 years, SD = 1.69; 54% females) completed a battery of anonymous questionnaires on academic burnout, engagement with studies, social cognitive variables relevant to PCE use, and self-reported use of PCE substances and non-prescribed nutritional supplements. Three user groups emerged, namely non-users (51.9%, n = 180), single users of non-prescribed dietary supplements (25.4%, n = 88), and dual users of both non-prescribed dietary supplements and PCE (22.8%, n = 79). Multivariate analysis of variance indicated significant differences among the three user groups in intentions, attitudes, social norms, and anticipated regret toward PCE use. No significant differences were observed with respect to academic burnout and work engagement. The findings show that university students may engage in PCE use independent of their student experiences. Rather, a chemically assisted performance enhancement mindset seems to differentiate users from non-users of PCE substances.

Patients' webs of relations in the medical landscapes of Central Ukraine.

Village dwellers in Central Ukraine have access to various types of therapy that comprise diverse medical landscapes. Patients' movements within these landscapes are possible thanks to each person's web of relations. Medical landscapes are not fixed, but vary and dynamically change for each person, depending on their fluid and interchanging, hierarchical webs of mutual relations with other people, personal bodies, institutions, discourses, political powers, other non-human organisms, or objects such as medicines. This paper was inspired by the medicoscape concept (Hörbst and Krause 2004 ) as well as Ingold's idea of meshwork analyses of relations between various actors: in this case, patients, healers, a weak state, official healthcare providers, pharmacists and medicinal plants, in the context of patients' therapeutic choices. Self-medication based on herbal remedies is a very important feature of people's medical landscapes in Central Ukraine and usually the first therapy choice for most interlocutors. That is why this paper is focused on the presentation of the means through which people acquire knowledge about medicinal plants, and the ways they interact with plants and plants interact with them. In this way, showing the complexity of villagers' webs of relations is possible. The analysis is based on ethnographic research conducted between 2009 and 2013 in the Vinnytsia region (Central Ukraine).

Self-Care Strategies among Chinese Adolescent Girls with Dysmenorrhea: A Qualitative Study.

Little is known about how Chinese adolescent girls manage dysmenorrhea. This study aims to explore self-care strategies among Chinese adolescent girls with dysmenorrhea. The study uses a mixed methods design with two phases: a cross-sectional survey in phase I and semistructured interviews in phase II. This paper reports phase II. In line with the phase I findings, 28 adolescent girls with different characteristics (high or low levels of self-care behavior and pain intensity, who did or did not self-medicate, and who had or had not received menstrual education) were recruited for interviews. Content analysis was used for data analysis. Four categories emerged from the data: lifestyle changes, symptom management, communicating dysmenorrhea with others, and seeking medical advice. Girls selected their diets carefully and reduced physical activity during menstruation to avoid aggravating symptoms. Heat therapy commonly was employed for symptom management. A few girls self-medicated to obtain immediate relief from pain, but the majority expressed reservations about using medication because they worried about dependence and side effects. Some girls communicated dysmenorrhea with their family and friends, but the majority did not seek medical advice. The present study showed that girls employed various self-care strategies for dysmenorrhea, including some strategies stemming from traditional Chinese medicine. The findings revealed menstrual etiquette among Chinese adolescent girls with dysmenorrhea, and demonstrated that self-medication was not part of most girls' self-care. Understanding the self-care strategies of these girls is important, as it can help nurses develop a culturally-specific intervention to promote self-care among adolescent girls with dysmenorrhea.

Self-medication practices among undergraduate nursing and midwifery students in Australia: a cross-sectional study.

BACKGROUND: Self-medication is a global phenomenon and a major form of self-care. OBJECTIVES: To explore the self-medication practices of Australian nursing and midwifery students. METHODS: An online questionnaire that examined the prevalence of self-medication, reasons for self-medication, medications consumed and medication knowledge was distributed to student nurses and midwives at one university in Victoria, Australia. Data were collected between February and May 2014. RESULTS: Self-medication practices were reported in 91.7% (n = 110) of students. Students reported the main reason for self-medication was to play an active role in their health. The incidence of stress was high (n = 82, 74.5%), along with back pain (n = 84, 76.4%) and nearly half the students (n = 46, 42.2%) reported using antibiotics that were prescribed for a previous health problem. CONCLUSION: Self-medication practices were common in this student cohort and some results give rise to concern for the general wellbeing of our future nursing and midwifery workforce.

Longitudinal analysis of associations between women's consultations with complementary and alternative medicine practitioners/use of self-prescribed complementary and alternative medicine and menopause-related symptoms, 2007-2010.

OBJECTIVE: This study aims to determine associations between consultations with complementary and alternative medicine (CAM) practitioners/use of self-prescribed CAM and menopause-related symptoms. METHODS: Data were obtained from the Australian Longitudinal Study on Women's Health. Generalized estimating equations were used to conduct longitudinal data analyses, which were restricted to women born in 1946-1951 who were surveyed in 2007 (survey 5; n = 10,638) and 2010 (survey 6; n = 10,011). RESULTS: Women with menopause-related symptoms were more likely to use self-prescribed CAM but were not more likely to consult a CAM practitioner. Overall, CAM use was lower among women who had undergone hysterectomy or women who had undergone oophorectomy, compared with naturally postmenopausal women, and decreased with increasing age of postmenopausal women. Weak associations between CAM use and hot flashes were observed. Women experiencing hot flashes were more likely to consult a massage therapist (odds ratio, 1.09; 95% CI, 1.00-1.20) and/or use self-prescribed herbal medicines (odds ratio, 1.13; 95% CI, 1.03-1.23) than women not experiencing hot flashes. CONCLUSIONS: Consultations with CAM practitioners and use of self-prescribed CAM among naturally or surgically postmenopausal women are associated with menopause-related symptoms. Our study findings should prompt healthcare providers, in particular family medicine practitioners, to be cognizant of clinical evidence for CAM typically used for the management of common menopause-related symptoms in their aim to provide safe, effective, and coordinated care for women.

"Just Advil": Harm reduction and identity construction in the consumption of over-the-counter medication for chronic pain.

Direct-to-consumer marketing has sparked ongoing debate concerning whether ads empower consumers to be agents of their own care or shift greater control to the pharmaceutical industry. Ads for over-the-counter (OTC) medications in particular portend to offer simple, harmless solutions for meeting the demands of social life. Rather than join the longstanding debate between consumer agency and social control in pharmaceutical advertising, I approach self-medication with over-the-counter (OTC) analgesics using Harm Reduction as a framework. From this perspective, consumption of OTC analgesics by chronic pain sufferers is a means of seeking some level of relief while also avoiding the stigma associated with prescription pain medication. Qualitative methods are used to analyze data from two sources: (1) semi-structured qualitative interviews with 95 participants in a trial examining the effectiveness of Traditional Chinese Medicine for Temporomandibular Disorders (TMD) from 2006 to 2011 in Tucson, AZ and Portland, OR; and (2) print, online, and television advertisements for three major brands of OTC pain medication. Participants described their use of OTC medications as minimal, responsible, and justified by the severity of their pain. OTC medication advertising, while ostensibly ambiguous and targeting all forms of pain, effectively lends support to the consumption of these medications as part of the self-projects of chronic pain sufferers, allowing them to reconcile conflicting demands for pain relief while being stoic and maintaining a positive moral identity. Describing OTC medication as "just over-the-counter" or "not real pain medication," sufferers engage in ideological harm reduction, distinguishing themselves from "those people who like taking pain medication" while still seeking relief. Justifying one's use of OTC medication as minimal and "normal," regardless of intake, avoids association with the addictive potential of prescription pain medications and aligns the identity of the chronic pain sufferer with a culturally sanctioned identity as stoic bearer of pain.

Factors associated with self medication practice among pregnant mothers attending antenatal care at governmental health centers in Bahir Dar city administration, Northwest Ethiopia, a cross sectional study.

INTRODUCTION: Studies in different parts of the world indicate that there is high level use of self medication among pregnant women. But there are no scientific evidences on it and factors associated with it in Bahir Dar city administration. The aim of this study was therefore to assess level of self medication and identify factors associated with it among pregnant women attending ANC service at governmental health centers in Bahir Dar city administration. METHODS: Institution based cross-sectional study was conducted from June 20-July 10, 2013. Data were collected using structured questionnaire and analyzed using SPSS version 16.0. Back ward logistic regression model was used to assess level of association with self medication practice. RESULTS: A total of 510 pregnant women were included in the study. Of these, 25.1% reported self-medication during the current pregnancy. Self medication during pregnancy was significantly associated with gravida (AOR = 2.1, 95% CI: 1.3-3.4), maternal illness on the date of interview (AOR = 4.8, 95% CI: 2.9-8.0) and location of health facility (AOR = 4.6; 95% CI: 2.9-7.4). CONCLUSION: A considerable proportion of pregnant women practiced self-medication during their pregnancy with modern medications or traditional herbs. Mothers who were multi gravida, who had maternal illness on the date of interview and who were attending antenatal care were more likely to practice self medication.

Low dispositional mindfulness predicts self-medication of negative emotion with prescription opioids.

OBJECTIVES: Although evidence is mounting that opioids are abused to self-medicate negative emotions, little is known about the traits and factors linked to opioid self-medication. One potentially crucial psychological correlate is dispositional mindfulness. Thus, the purpose of this study was to describe the prevalence of opioid self-medication among a treatment-seeking sample of prescription opioid-dependent individuals and specifically examine the relationship between dispositional mindfulness and opioid self-medication. METHODS: Participants in acute detoxification or intensive outpatient treatment for prescription opioid dependence (n = 79) were recruited from a regional hospital's addictions treatment unit for this cross-sectional study. Sociodemographic data were collected along with surveys of opioid self-medication, pain level, and dispositional mindfulness. RESULTS: Self-medication of negative affective states with opioids was quite common, with 94.9% of individuals sampled reporting self-medication behaviors. In adjusted analyses, individuals engaging in more frequent opioid use tended to self-medicate negative emotions with opioids more often than those engaging in more intermittent opioid use (ß = 0.33; P < 0.05). Importantly, irrespective of opioid use frequency and other clinical and sociodemographic covariates, dispositional mindfulness was inversely associated with opioid self-medication (ß = -0.42; P < 0.001), such that less mindful individuals reported using opioids more frequently to self-medicate negative emotions. CONCLUSIONS: Self-medication of negative emotions with opioids was prevalent in this sample and related to low dispositional mindfulness. Plausibly, increasing mindfulness may decrease opioid self-medication. Addictive automaticity and emotion regulation are discussed as potential mechanisms linking low dispositional mindfulness and self-medication.

Social, cultural and economic factors associated with self-medication.

INTRODUCTION: Self-medication is an increasingly frequent phenomenon worldwide; some studies suggest that there is a relationship with socio-economic and cultural factors. OBJECTIVE: To determine the prevalence of self-medication and its related factors in a Colombian city. MATERIALS AND METHODS: Cross-sectional descriptive study, in Pereira, Colombia. We selected 414 adults using simple randomization sampling with houses used as the observational unit. The IRIS-AM instrument was used to collect the information required. RESULTS: Four hundred and fourteen (414) people were interviewed, 62.6% were females, and mean age was 44 years; 77.5% of the sample had self-medicated at least once in their life and 31.9% during the last month. The most commonly used medications were: analgesics and antipyretics (44.3%), non-steroidal anti-inflammatory drugs and anti-rheumatic medication (36.4%), and anti-histamine medication (8.5%). The most commonly self-medicated symptoms were: headache (55.7%), cold (16.2%) and muscular pain (13.2%). Multivariate analysis revealed an association between self-medication throughout life and storing medications at home, and between a high level of education and having a favorable opinion of self-medication. Storing medications at home and recommending them to others were associated with self-medication during the previous 30 days. CONCLUSION: Self-medication rates were found to be similar to those reported globally, but there is not an established pattern for this practice. Associations were found between social and demographic variables and self-medication, which require further characterization. Intention to self-medicate has not been well-described in other studies, and may be an important indicator which will contribute to future understanding of this phenomenon.

Social, cultural and economic factors associated with self-medication / Factores económicos, sociales y culturales asociados con la automedicación

Introducción. La automedicación es un fenómeno cada vez más frecuente a nivel mundial. Los estudios en este campo sugieren que hay una relación entre la automedicación y diversos factores sociodemográficos y económicos. Objetivo. Determinar la prevalencia de la automedicación y los factores relacionados en Pereira, Colombia. Materiales y métodos. Estudio descriptivo de corte transversal llevado a cabo en la población de Pereira. Se hizo un muestreo aleatorio por afijación proporcional en 414 adultos, y se desarrolló y aplicó la encuesta IRIS-AM ( Instrument for Systematic Data Collection of Self-Medication ). Resultados. Se encuestaron 414 personas, 62,6 % de las cuales eran mujeres; el promedio de edad fue de 44 años. La prevalencia de la automedicación fue de 77,5 % a lo largo de la vida y de 31,9 % en los 30 días previos. Los medicamentos más comúnmente utilizados fueron los analgésicos y antipiréticos (44,3 %), los antiinflamatorios no esteroideos (36,4 %), y los antihistamínicos (8,5 %). Los síntomas que llevaron a la automedicación con mayor frecuencia fueron la cefalea (55,7 %), el resfriado (16,2 %) y el dolor muscular (13,2 %). Los análisis multivariados mostraron asociación entre la automedicación a lo largo de la vida y guardar medicamentos en casa, así como entre tener un nivel superior de escolaridad y estar a favor de la automedicación. Los factores referentes a almacenar medicamentos y recomendarlos a otros se asociaron con la automedicación en los 30 días previos. Conclusiones. La prevalencia de la automedicación hallada en este estudio fue similar a la reportada previamente a nivel mundial; aun así, no existe un patrón establecido para esta práctica. Se evidenciaron las variables sociodemográficas asociadas con la automedicación, las cuales requieren una mejor caracterización. La intención de recurrir a la automedicación ha sido poco estudiada y podría ser un indicador importante para la medición y comprensión de este fenómeno.

Multivitamin and protein supplement use is associated with positive mood states and health behaviors in US Military and Coast Guard personnel.

Approximately 60% of Armed Forces personnel regularly consume dietary supplements (DSs). We investigated the association of mood and health behaviors with multiple classes of DSs in military and Coast Guard personnel (N = 5536). Participants completed a survey of DS use and the Quick Mood Scale to assess mood domains of wakeful-drowsiness, relaxed-anxious, cheerful-depressed, friendly-aggression, clearheaded-confused, and well coordinated-clumsy. Supplements were categorized as multivitamin/minerals (MVM), individual vitamin/minerals, protein/amino acid supplements (PS), combination products (C), herbals (H), purported steroid analogs, (S) and other (O). One-way analyses of covariance assessed associations of DSs and perceived health behavior with mood controlling for age. Logistic regression determined associations between DS use and health behavior. Users of MVM and PS reported feeling significantly (P < 0.05) more awake, relaxed, cheerful, clearheaded, and coordinated. Participants using PS and S reported feeling less friendly (more aggressive, P < 0.02). Users of MVM and PS were more likely to report their general health, eating habits, and fitness level as excellent/good (P < 0.05). Participants reporting health behaviors as excellent/good were more (P < 0.01) awake, relaxed, cheerful, friendly, clearheaded, and coordinated. As no known biological mechanisms can explain such diverse effects of MVM and PS use on multiple mood states, health, eating habits, and fitness, we hypothesize these associations are not causal, and DS intake does not alter these parameters per se. Preexisting differences in mood and other health-related behaviors and outcomes between users versus nonusers of DSs could be a confounding factor in studies of DSs.

Older adults' use of complementary and alternative medical therapies to resist biomedicalization of aging.

Taking its cue from Estes and Binney's (1989) assertion that individual and subjective views of aging often reflect a hegemony characteristic of biomedicalization, this study assesses the subjective views that a group of older adult users of CAM therapies have of aging, health, healing, and self care. Reflexive sociological interviews with 24 men and women over the age of 55 are used to show how participants use CAM as an embodied means to resist biomedicalization of aging. Four themes emerge as in part explaining the appeal of CAM therapies for older adults: "intergenerational angst"; "iatrogenesis"; "aging as deterioration"; and "optimistic alternatives". In a cultural context in which aging has been transformed into a medical matter, older adults who seek out CAM do so as part of an effort to gain individual control over their aging bodies and health. These findings provide further evidence that older adults have adopted discourses of individual responsibility for health through self care behavior and that the growing trend towards therapeutic pluralism entails both elements of medicalization and demedicalization.

Reduced self-control leads to disregard of an unfamiliar behavioral option: an experimental approach to the study of neuroenhancement.

BACKGROUND: Neuroenhancement (NE), the use of psychoactive substances in order to enhance a healthy individual's cognitive functioning from a proficient to an even higher level, is prevalent in student populations. According to the strength model of self-control, people fail to self-regulate and fall back on their dominant behavioral response when finite self-control resources are depleted. An experiment was conducted to test the hypothesis that ego-depletion will prevent students who are unfamiliar with NE from trying it. FINDINGS: 130 undergraduates, who denied having tried NE before (43% female, mean age = 22.76 ± 4.15 years old), were randomly assigned to either an ego-depletion or a control condition. The dependent variable was taking an "energy-stick" (a legal nutritional supplement, containing low doses of caffeine, taurine and vitamin B), offered as a potential means of enhancing performance on the bogus concentration task that followed. Logistic regression analysis showed that ego-depleted participants were three times less likely to take the substance, OR = 0.37, p = .01. CONCLUSION: This experiment found that trying NE for the first time was more likely if an individual's cognitive capacities were not depleted. This means that mental exhaustion is not predictive for NE in students for whom NE is not the dominant response. Trying NE for the first time is therefore more likely to occur as a thoughtful attempt at self-regulation than as an automatic behavioral response in stressful situations. We therefore recommend targeting interventions at this inter-individual difference. Students without previous reinforcing NE experience should be provided with information about the possible negative health outcomes of NE. Reconfiguring structural aspects in the academic environment (e.g. lessening workloads) might help to deter current users.

Caffeinated-beverage consumption and its association with socio-demographic characteristics and self-perceived academic stress in first and second year students at the University of Puerto Rico Medical Sciences Campus (UPR-MSC).

OBJECTIVE: To determine the association between caffeinated-beverage consumption, self-perceived academic load, and self-perceived stress levels in first and second year students at UPR-MSC. METHODS: A descriptive epidemiological study was performed using a self-administered anonymous questionnaire given to a representative stratified sample of 275 students. Questions included information regarding socio-demographic characteristics, academic load and stress indicators, and caffeinated-beverage consumption. Chi2 was used to assess the associations between these variables. RESULTS: Most participants were women (68%), aged 21-30 years (88%), with low annual household incomes (43%). Most perceived their academic loads as being heavy (68%), and most perceived their academic stress levels as being moderate (37%). Academic load was significantly correlated with stress level (p<0.001). About 88% of the participants reported consuming caffeinated beverages; of those, 87% drank soft drinks, 83% drank coffee, 56% drank hot chocolate, 40% drank tea, and 29% drank energy drinks, all of which were--according to the participants (54%)--used mainly to stay awake. Soft drinks and coffee intake increased in periods of high stress, and many (49%) reported that these beverages were useful for coping with stress. Energy drinks, in particular, were consumed more often by men compared to women (p<0.05). None of these beverages were significantly associated with academic stress or load. CONCLUSION: Consuming caffeinated beverages is a popular practice among participants in this sample, with soft drinks and coffee being the ones that are the most frequently consumed. No associations were found between the consumption of caffeinated beverages and academic stress or load.

Knowledge, attitude and practice of herbal remedies in a group of infertile couples.

The aim of this study was to evaluate knowledge, attitude and practice of herbal remedies (HRs) in infertile patients. This was a cross sectional study in a referral infertility care center. Three hundred and six outpatients, both women and men, presenting for the first time with complaint of infertility at Arash hospital, were recruited. Verbal consent for participation was received. A self administered questionnaire was used. Main outcome measure was knowledge, attitude and practice of patients toward herbal medications. 47.3% of participants were knowledgeable of HRs with female gender and lower educational background being the associated factors in knowledge. 43.4% of patients with significant female dominancy had positive attitude toward HRs. 31% of participants were using HRs. Only 3.2% of those using HRs informed their physician. The most common health condition promoting herbal use was psychological (33.3%) and gastrointestinal (30.8%) disorders. 3.5% of participants used HRs as fertility treatment which was significantly observed in women and those with lower levels of formal education. A considerable proportion of our population had used HRs without sufficient knowledge and had positive attitude toward HRs. More importantly, patients did not disclose their use of HRs to physicians. Therefore, physicians should inquire about the use of alternative remedies and provide patients with appropriate information.

From Kratom to mitragynine and its derivatives: physiological and behavioural effects related to use, abuse, and addiction.

Kratom (or Ketum) is a psychoactive plant preparation used in Southeast Asia. It is derived from the plant Mitragyna speciosa Korth. Kratom as well as its main alkaloid, mitragynine, currently spreads around the world. Thus, addiction potential and adverse health consequences are becoming an important issue for health authorities. Here we reviewed the available evidence and identified future research needs. It was found that mitragynine and M. speciosa preparations are systematically consumed with rather well defined instrumentalization goals, e.g. to enhance tolerance for hard work or as a substitute in the self-treatment of opiate addiction. There is also evidence from experimental animal models supporting analgesic, muscle relaxant, anti-inflammatory as well as strong anorectic effects. In humans, regular consumption may escalate, lead to tolerance and may yield aversive withdrawal effects. Mitragynine and its derivatives actions in the central nervous system involve µ-opioid receptors, neuronal Ca²âº channels and descending monoaminergic projections. Altogether, available data currently suggest both, a therapeutic as well as an abuse potential.
