Levels of prolactin, progesterone, estradiol, luteinizing hormone and follicle stimulating hormone in infertile women in Calabar, Nigeria
Background: Infertility is defined as the inability of a couple to achieve conception despite frequent unprotected, well timed sexual intercourse for one year duration. Therefore the aim of our study was to estimate the levels of progesterone, estradiol, luteinizing hormone, follicle stimulating hormone in infertile women.Methods: One hundred and two (102) volunteers infertile women; aged 20-45 years were recruited from the University of Calabar Teaching Hospital. They were further divided into three groups based on their prolactin levels; namely those with normal ovarian hormones value (normal); (n=32), those with prolactin values between 25 â 60ng/ml (moderate) (n=46) and those with prolactin values >60ng/ml (high); (n=24). Sixty (60) apparently healthy, age matched women were also selected to serve as the control group. Sera samples were obtained from the subjects and the following parameters were measured using DRG Enzyme Linked Immunosorbent Assay; prolactin, progesterone, estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH).Results: In this study, the prolactin and E2 values were significantly (p0.05). There was a positive correlation between E2 and prolactin, progesterone and FSH (r=0.239; 0.368 and 0.217 respectively, pË0.05) and a strong positive correlation between FSH and LH (r=0.677) in the infertile women.Conclusions: There was a positive correlation between E2 and progesterone with reduced concentration of FSH in women with normal, moderate and high prolactin concentrations. Therefore, there is need for anti-oxidant therapy or supplements for these subjects
Abnormal ECG Findings in Athletes: Clinical Evaluation and Considerations.
PURPOSE OF REVIEW: Pre-participation cardiovascular evaluation with electrocardiography is normal practice for most sporting bodies. Awareness about sudden cardiac death in athletes and recognizing how screening can help identify vulnerable athletes have empowered different sporting disciplines to invest in the wellbeing of their athletes. RECENT FINDINGS: Discerning physiological electrical alterations due to athletic training from those representing cardiac pathology may be challenging. The mode of investigation of affected athletes is dependent on the electrical anomaly and the disease(s) in question. This review will highlight specific pathological ECG patterns that warrant assessment and surveillance, together with an in-depth review of the recommended algorithm for evaluation
Assessing Communities of Practice in health policy : A conceptual framework as a first step towards empirical research
Peer reviewe
A scoping review examining the integration of exercise services in clinical oncology settings
Background
Addressing questions surrounding the feasibility of embedding exercise service units in clinical oncology settings is imperative for developing a sustainable exercise-oncology clinical pathway. We examined available literature and offered practical recommendations to support evidence-based practice, policymaking, and further investigations.
Methods
Four thousand eight hundred sixty-three unique records identified in Embase, CINAHL, MEDLINE, Web of Science Core Collection, and ProQuest (Health and Medicine) were screened for studies that recruited cancer patients, assessed the co-location of exercise service and cancer treatment units, and reported findings on service implementation. Evidence from six studies providing data from over 30 programs was integrated using narrative synthesis.
Results
Service implementation was relatively modest across the included studies. Exercise services were delivered by physiotherapists, exercise physiologists, and kinesiologists and funded mainly through grants and private donations, with staff salaries accruing as the major expense. Service penetration, adoption, and acceptability were generally low. However, studies recorded high clinician/patient satisfaction. Major barriers to service integration were limited funding, lack of detailed implementation plan, and low organizational buy-in. Common reasons for non-utilization, missed sessions, and dropouts were lack of interest, unwellness, hospital readmission, disease progression, and adverse skeletal events.
Conclusion
Implementing exercise services in clinical oncology settings seems an effective approach for increasing access to exercise-based rehabilitation for individuals on cancer treatment. While this model appears feasible for patients/clinicians, efforts are required to optimize service integration both in the short and long term. Key priorities include seeking [local] actions to address issues relating to funding and organizational buy-in. Important considerations may include developing an implementation plan to guide the implementation process, expanding the patient core management team to include staff from the exercise rehabilitation unit, and exploring the role of patient feedback in increasing clinician participation (e.g., treating oncologists and nurses) in the referral process. Future research should consider effective strategies to promote patientsâ sense of self-efficacy and behavioral control and, further, the place of audit and feedback in improving exercise service delivery and overall service implementation
52 Genetic Loci Influencing Myocardial Mass.
BACKGROUND: Myocardial mass is a key determinant of cardiac muscle function and hypertrophy. Myocardial depolarization leading to cardiac muscle contraction is reflected by the amplitude and duration of the QRS complex on the electrocardiogram (ECG). Abnormal QRS amplitude or duration reflect changes in myocardial mass and conduction, and are associated with increased risk of heart failure and death. OBJECTIVES: This meta-analysis sought to gain insights into the genetic determinants of myocardial mass. METHODS: We carried out a genome-wide association meta-analysis of 4 QRS traits in up to 73,518 individuals of European ancestry, followed by extensive biological and functional assessment. RESULTS: We identified 52 genomic loci, of which 32 are novel, that are reliably associated with 1 or more QRS phenotypes at p < 1 à 10(-8). These loci are enriched in regions of open chromatin, histone modifications, and transcription factor binding, suggesting that they represent regions of the genome that are actively transcribed in the human heart. Pathway analyses provided evidence that these loci play a role in cardiac hypertrophy. We further highlighted 67 candidate genes at the identified loci that are preferentially expressed in cardiac tissue and associated with cardiac abnormalities in Drosophila melanogaster and Mus musculus. We validated the regulatory function of a novel variant in the SCN5A/SCN10A locus in vitro and in vivo. CONCLUSIONS: Taken together, our findings provide new insights into genes and biological pathways controlling myocardial mass and may help identify novel therapeutic targets
Impact of internet of things (IoT) in disaster management: a task-technology fit perspective
YesDisaster management aims to mitigate the potential damage from the disasters, ensure immediate and suitable assistance to the victims, and attain effective and rapid recovery. These objectives require a planned and effective rescue operation post such disasters. Different types of information about the impact of the disaster are, hence, required for planning an effective and immediate relief operation. The IoT technology available today is quite mature and has the potential to be very useful in disaster situations. This paper analyzes the requirements for planning rescue operation for such natural disasters and proposes an IoT based solution to cater the identified requirements. The proposed solution is further validated using the task-technology fit (TTF) approach for analyzing the significance of the adoption of IoT technology for disaster management. Results from the exploratory study established the core dimensions of the task requirements and the TTF constructs. Results from the confirmatory factor analysis using PLS path modelling, further, suggest that both task requirements and IoT technology have significant impact on the IoT TTF in the disaster management scenario. This paper makes significant contributions in the development of appropriate constructs for modeling TTF for IoT Technology in the context of disaster management
