Levothyroxine Administration during Ramadan: A Prospective Randomized Controlled Trial.

BACKGROUND AND AIM: We have previously shown in a retrospective analysis that the plasma thyroid-stimulating hormone (TSH) rises significantly post-Ramadan in levothyroxine-treated hypothyroid patients, possibly as a result of lifestyle alterations and time restrictions during the nonfasting period from dusk until dawn. The aim of this study is to determine the best time to instruct patients to take levothyroxine during Ramadan so as to minimize changes in thyroid function tests during this period. METHODS: In a randomized prospective design, hypothyroid patients taking levothyroxine were randomized to receive instructions to take levothyroxine at one of the following 3 times during Ramadan: (group 1) at dusk 30-min before Iftar meal, (group 2) 3 or more hours after Iftar meal, or (group 3) at dawn 30-min before Suhur meal. Thyroid function tests were performed within 3 months before Ramadan and within 6 weeks post-Ramadan. Data from patients with at least 1 blood test before or after Ramadan were analyzed using mixed-effects regression models. RESULTS: Plasma TSH levels were available at one or more time points for 148 patients, group 1 (n = 50), group 2 (n = 46), and group 3 (n = 52). A statistically significant within-patient increase in plasma TSH was seen in patients at the 25th percentile pre-Ramadan in groups 2 and 3 (p values <0.001), but not in group 1. A statistically significant within-patient decrease in plasma TSH was found in patients at the 75th percentile in group 1 only. For patients at the 50th percentile pre-Ramadan, no statically significant within-patient changes were found, though descriptively, increases in plasma TSH were observed for groups 2 and 3, while a decrease was observed in group 1. CONCLUSIONS: Our data suggest that instructing patients to take levothyroxine at the time of breaking the fast 30 min before the Iftar meal minimizes unfavorable changes in plasma TSH post-Ramadan. In contrast, instructing patients to take levothyroxine 3 h post-Iftar or 30 min before Suhur led to a greater rise in post-Ramadan TSH.

Lipid Control Post Coronary Artery Bypass Graft: One Year Follow-Up of a Middle-Eastern Cohort.

Background: Data on patient characteristics and provider practices in the management of lipids per the new guidelines in specific secondary prevention patients in the Middle East is limited. Objective: To explore patient characteristics and lipid management practices according to the new cholesterol guidelines in secondary prevention patients, up to one year following discharge for coronary artery bypass graft surgery (CABG). Methods: A retrospective chart review of patients discharged post CABG between February 2017 and February 2018 at a quaternary care centre in the Middle East. Patients were characterized by baseline demographics, comorbidities, and use of lipid lowering medications. Results: 189 patients were included in the analysis. Most were diabetic (70.9%) and classified as very high risk per the ACC/AHA guidelines (84.1%) and as extremely high risk per the AACE guidelines (85.2%). Most patients (93.1%) were discharged on high intensity statin. About one third (28.6%) were never seen or only followed once within the first 2 weeks post discharge. Of those who continued to follow up beyond 3 months and within 1 year of discharge (44.4%), about half (51.2%) had follow-up lipid panels performed. Patients who followed up and were seen by a cardiologist were five times more likely to have lipid panels ordered than those seen solely by a CT surgeon. Of those with follow-up lipid panels beyond 3 months: 59.3% achieved LDL goal of <70 mg/dL and 29% achieved LDL <55 mg/dL based on their respective goals. Conclusions: Most patients undergoing CABG in a quaternary care centre in the Middle East are high risk ASCVD. Nonetheless, lipid goals are not commonly achieved nor routinely monitored. Providers will need to transition from the previous risk stratification and statin-only focused approach to adopt the most recent guidelines.

Role of nephrology pharmacists in the management of anemia in outpatient dialysis units: A Canadian model
.

INTRODUCTION: Hemodialysis patients frequently suffer from anemia. Proper utilization of therapies such as iron and erythropoiesis-stimulating agents (ESAs) is crucial to attain symptom management and established hemoglobin targets. The purpose of this study was to evaluate the clinical and financial impact of nephrology-trained pharmacists on anemia management in these patients. MATERIALS AND METHODS: A retrospective study of outpatient hemodialysis patients observed between January 2010 and December 2011. In December 2010, pharmacists were tasked to manage anemia under a medical directive. Primary endpoints were compared across years using a mixed-effects model strategy. An unstructured random effects correlation matrix was utilized to capture patient-level variation in 2010 and 2011, separately. RESULTS: Of 202 patients identified, 163 contributed in both years, 57% were males, aged 65.18 ± 16.3 years. Hemoglobin levels were 10.95 ± 0.95 and 10.83 ± 0.94 g/dL in 2010 vs. 2011, respectively (p = 0.158), while the transfusion rate was 1.3% and 1.8%, respectively (p = 0.196). Ferritin levels of 273.5 ± 22 and 317.1 ± 12 ng/mL (p = 0.0019), iron saturation 0.30 ± 0.11 and 0.30 ± 0.05 (p = 0.838), and parenteral iron dose of 215.4 ± 100.2 and 317.1 ± 123.7 mg, respectively (p = 0.996), were identified. Finally, the average weekly ESA dose in 2010 was higher and trending up as compared to 2011 where it significantly trended down. The amount of intravenous erythropoietin alfa was 12,315.6 ± 76 vs. 11,364.1 ± 52 units/week, respectively (p = 0.0556) with expenditure of 2.8 million Canadian dollars in 2010 vs. 2.3 million Canadian dollars in 2011. CONCLUSION: The participation of a nephrology pharmacist resulted in favorable outcomes in dose optimization, decreased expenditure, and positive trends in therapeutic goal achievement.

Impact of Lifestyle Changes During Ramadan on Thyroid Function Tests in Hypothyroid Patients Taking Levothyroxine.

OBJECTIVE: The holy month of Ramadan poses a challenge for levothyroxine-treated patients due to altered eating habits and time restrictions. The aim of this study was to examine the impact of lifestyle changes during Ramadan on thyroid function tests in hypothyroid patients taking levothyroxine in the United Arab Emirates. METHODS: Retrospective design whereby levothyroxine-treated hypothyroid patients who had thyroid function tests within 3 months pre-Ramadan and within 2 months post-Ramadan were included. We looked at adherence to levothyroxine, eating pattern, and levothyroxine administration in relation to meal times during Ramadan. Pre- and post-Ramadan thyroid function tests and the potential impact of independent variables using a random-intercept mixed effects linear model were examined. RESULTS: A total of 112 patients (89 females) were recruited in the study, with a mean age ± standard error (SE) of 44.70±1.36 years (range, 19.0 to 79.0 years). The mean thyroid-stimulating hormone (TSH) within 3 months before Ramadan was 1.809±0.094 mIU/L (median, 41.5 days; interquartile range [IQR], 25.0 to 73.0 days), while the mean TSH within 2 months post-Ramadan was higher at 3.072±0.312 mIU/L (median, 27.5 days; IQR, 14.0 to 42.0 days). Post-Ramadan, 36 out of 112 patients had a plasma TSH outside of the normal reference range. The independent variable outcomes model showed that older patients and males were more likely to have an increased plasma TSH post-Ramadan. There was no relationship between the time of levothyroxine administration and change in TSH level. CONCLUSION: Levothyroxine-treated hypothyroid patients showed a significant increase in plasma TSH post-Ramadan, amounting to 2.525 standard deviations, with older patients and males more likely to be affected. ABBREVIATIONS: IQR = interquartile range; T4 = thyroxine; TSH = thyroid-stimulating hormone.

Forced Sex and Sexual Consent Among College Women.

INTRODUCTION: Female college students, aged 18-25 years, are at high risk for sexual violence compared with women of other age groups. Lack of clear consent is a preceding and defining component of forced sex and sexual violence. This study explored the association between sexual consent awareness, attitudes, and beliefs and a history of forced sex among a sample of college women. In addition, the level of alcohol use among this group was examined. METHODS: A cross-sectional electronic survey was sent to approximately 5900 female students enrolled at a large public university in the northeastern United States. Sexual consent was measured with the Sexual Consent Scale-Revised, and alcohol use was measured with the Alcohol Use Disorders Identification Test-Consumption Items. Logistic regression models were used to examine the differences in sexual consent scores based on a history of forced sex. RESULTS: The final sample included 925 students. Twenty-two percent of participants reported a history of forced sex; more than half (59%) reported alcohol use before sexual activity. Women with greater awareness of sexual consent were significantly more likely to have a history of forced sex. Women who utilize more nonverbal, indirect approaches to communicating sexual consent were significantly less likely to have a history of forced sex compared with women with no history of forced sex. DISCUSSION: These findings highlight high rates of forced sex and alcohol use in a sample of college women and explicate sexual consent awareness and communication behaviors associated with a history of forced sex.

The effects of intimate partner violence duration on individual and partner-related sexual risk factors among women.

INTRODUCTION: Intimate partner violence (IPV) is associated with risk of sexually transmitted infections (STIs) and HIV among women, but less is known about mechanisms of this association and if length of relationship violence is a factor. The purpose of this study was to explore the relationship between the duration of IPV and both individual and partner-related sexual risk factors that may increase women's risk for STIs and HIV. METHODS: This was a secondary analysis of data collected from the medical records of 2000 women. Four distinct categories defined the duration of partner violence: violence in the past year only, past year and during the past 5 years, past year plus extending for greater than 5 years, and no past year violence but a history of partner violence. Logistic regression models were used to examine the associations between the duration of partner violence and individual sexual risk behaviors (eg, number of sexual partners, drug and/or alcohol use, anal sex) and partner-related sexual risk factors (eg, nonmonogamy, STI risk, condom nonuse). RESULTS: Nearly 30% of the women in the study reported a history of partner violence during their lifetime. All of the individual risk factors, as well as partner-related risk factors, were significantly associated (P < .05) with partner violence and duration of violence. DISCUSSION: The study findings extend the knowledge related to partner violence as a risk factor for STIs/HIV, highlighting the effects of partner violence duration on the health of women. Assessing for lifetime experiences of partner violence may improve outcomes for women and their families.

Chronicity of partner violence, contraceptive patterns and pregnancy risk.

BACKGROUND: Partner violence may interfere with a woman's ability to maintain continuous contraception and therefore contribute to increased risk of pregnancy among childbearing women. STUDY DESIGN: A retrospective review of medical records (N=2000) was conducted from four family planning clinics in the northeast United States. Eligibility criteria for inclusion were as follows: (1) female, (2) reproductive age (menarche through menopause), (3) seeking reproductive services and (4) clinic visit for annual gynecologic exam between 2006 and 2011. RESULTS: Partner violence was documented in 28.5% (n=569) of medical records. Chronicity of violence influenced contraceptive patterns and pregnancy risk. Women reporting past year partner violence only [odds ratio (OR)=10.2] and violence during the last 5 years (OR=10.6) had the highest odds of not using a current method of contraception. Women reporting recent exposure to violence were most likely to change birth control methods and use emergency contraception (OR=6.5). Women experiencing any history of violence reported more frequent contraceptive method changes during the previous year. CONCLUSIONS: A history of partner violence was common among women utilizing family planning services. The chronicity of violence appeared to play a significant role in contraceptive method changes, types of methods used and pregnancy risk. These results may be one explanation for increased pregnancies among women who experience partner violence.
