Cluster headache: an update on clinical features, epidemiology, pathophysiology, diagnosis, and treatment.

Cluster headache (CH) is one of the worst primary headaches that remain underdiagnosed and inappropriately treated. There are recent advances in the understanding of this disease and available treatments. This paper aims to review CH's recent clinical and pathophysiological findings, diagnosis, and treatment. We performed a narrative literature review on the socio-demographics, clinical presentations, pathophysiological findings, and diagnosis and treatment of CH. CH affects 0.1% of the population with an incidence of 2.07-9.8/100,00 person-years-habitants, a mean prevalence of 53/100,000 inhabitants (3-150/100,000 inhabitants). The male-to-female ratio remains inconclusive, as the ratio of 4.3:1 has recently been modified to 1.3-2.6, possibly due to previous misdiagnosis in women. Episodic presentation is the most frequent (80%). It is a polygenetic and multifactorial entity that involves dysfunction of the trigeminovascular system, the trigeminal autonomic reflex, and the hypothalamic networks. An MRI of the brain is mandatory to exclude secondary etiologies. There are effective and safe pharmacological treatments oxygen, sphenopalatine, and great occipital nerve block, with the heterogeneity of clinical trial designs for patients with CH divided into acute, transitional, or bridge treatment (prednisone) and preventive interventions. In conclusion, CH remains underdiagnosed, mainly due to a lack of awareness within the medical community, frequently causing a long delay in reaching a final diagnosis. Recent advances in understanding the principal risk factors and underlying pathophysiology exist. There are new therapeutic possibilities that are effective for CH. Indeed, a better understanding of this challenging pathology will continue to be a subject of research, study, and discoveries in its diagnostic and therapeutic approach.

Cluster headache: state of the art in treatment.

Cluster headache (CH) is the most common and devastating autonomic headache with multiple and recent advances in treatment. However, it usually goes unrecognized and is found to have a delayed and inappropriate treatment. This paper aims to review the current therapeutic options for patients with CH. We conducted a narrative literature review on the treatments available for this condition using the American Academy of Neurology (AAN) classification of therapeutic evidence. We found effective and safe pharmacological and non-pharmacological therapies with heterogeneity of clinical trial designs for patients with CH, and they are divided into three phases, namely, transitional, acute, and preventive interventions. Prednisone (A) is the most studied treatment in the transitional phase; acute attacks are treated using triptans (A), oxygen (A), and non-invasive transcutaneous vagal nerve stimulation (A). Verapamil (A) and monoclonal antibodies (possible A) are considered the first options in preventive treatments, followed by multiple pharmacological and non-pharmacological options in prophylactic treatments. In conclusion, numerous effective and safe treatments are available in treating patients with episodic, chronic, and pharmacoresistant CH according to the clinical profile of each patient.

FEEDBACK trial - A randomised control trial to investigate the effect of personalised feedback and financial incentives on reducing the incidence of road crashes.

BACKGROUND: Road crashes continue to pose a significant threat to global health. Young drivers aged between 18 and 25 are over-represented in road injury and fatality statistics, especially the first six months after obtaining their license. This study is the first multi-centre two-arm parallel-group individually randomised controlled trial (the FEEDBACK Trial) that will examine whether the delivery of personalised driver feedback plus financial incentives is superior to no feedback and no financial incentives in reducing motor vehicle crashes among young drivers (18 to 20 years) during the first year of provisional licensing. METHODS: A total of 3,610 young drivers on their provisional licence (P1, the first-year provisional licensing) will participate in the trial over 28 weeks, including a 4-week baseline, 20-week intervention and 4-week post-intervention period. The primary outcome of the study will be police-reported crashes over the 20-week intervention period and the 4-week post-intervention period. Secondary outcomes include driving behaviours such as speeding and harsh braking that contribute to road crashes, which will be attained weekly from mobile telematics delivered to a smartphone app. DISCUSSION: Assuming a positive finding associated with personalised driver feedback and financial incentives in reducing road crashes among young drivers, the study will provide important evidence to support policymakers in introducing the intervention(s) as a key strategy to mitigate the risks associated with the burden of road injury among this vulnerable population.

Clinical outcomes and complications of single anastomosis duodenal-ileal bypass with sleeve gastrectomy: A 2-year follow-up study in Bogotá, Colombia.

BACKGROUND: The global prevalence of obesity has increased over the past 40 years, and bariatric surgery has proven to be the most effective therapy for long-term weight loss. Its principles are based on modifying the brain-gut axis by altering the gastrointestinal anatomy and affecting the function of gastrointestinal hormones, thereby modifying satiety signals. Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) combines both techniques and has become an alternative to gastric bypass and biliopancreatic diversion procedures for treating severe obesity and associated metabolic diseases in selected patients. AIM: To describe the outcomes and complications of SADI-S. METHODS: We retrospectively analyzed the data of patients who underwent SADI-S laparoscopically at the Clínica Reina Sofía in Bogotá, Colombia. This study assessed the therapeutic effectiveness of SADI-S in terms of short-term preoperative clinical characteristics, postoperative complications, comorbidities, nutritional defi-ciencies, and intraoperative complications during a 2-year follow-up. RESULTS: Sixty-one patients with a mean body mass index (BMI) of 50 ± 7.1 kg/m2 underwent laparoscopic SADI-S. The mean operative time and hospital stays were 143.8 ± 42 min and 2.3 ± 0.8 d, respectively. The mean follow-up period was 18 mo, and the mean BMI decreased to 28.5 ± 12.2 kg/m2. The excess BMI loss was 41.8% ± 13.5%, and the weight loss percentage was 81.1% ± 17.0%. Resolution of obesity-related comorbidities, including type 2 diabetes mellitus, hypertension, dyslipidemia, and obstructive sleep apnea, was achieved and defined as complete or partial remission. No intraoperative complications were observed. Short-term complications were observed in four (6.8%) patients. However, larger studies with longer follow-up periods are required to draw definitive conclusions. CONCLUSION: SADI-S has a low intraoperative and postoperative complication rate and is effective for weight loss and improving obesity-related comorbidities, including hypertension, type 2 diabetes mellitus, dyslipidemia, and sleep apnea syndrome.

Evaluation of Acute Toxicity and Antioxidant Response of Earthworm Exposed to a Lignin-Modified Crosslinked Hydrogel.

Hydrogels are polymers of great importance due to their multiple applications, which have led to an exponential increase in their production. However, once they have fulfilled their function, they become waste and their ecotoxicological effects are unknown. The aim of the present study was to evaluate the acute toxicity and total antioxidant capacity of the earthworm (Eisenia fetida) exposed to a terpolymeric hydrogel (acrylic acid, acrylamide, and 2-acrylamido-2-methyl-1-propane-sulfonic acid) crosslinked with modified kraft lignin. Four different amounts of hydrogel per unit area were evaluated (0.0924, 0.1848, 0.9242, and 1.848 mg hydrogel/cm2) plus a control, and three replicates were performed for each group. Starting from the amount of 0.1848 mg hydrogel/cm2, the earthworms showed physiological and behavioral alterations; at higher amounts, 0.9242 and 1.848 mg hydrogel/cm2, more acute signs were observed with mortality rates of 51.7% and 100%, respectively. On the other hand, the antioxidant activity assay showed that the higher the hydrogel exposure amount, the higher the oxidative stress, as evidenced by lower antioxidant activity (67.09% inhibition of the ABTS●+ radical). Therefore, we concluded that the lignin-modified hydrogel generated oxidative stress and acute lethal toxic effects in Eisenia fetida.

Prevalence of Comorbidities and Polypharmacy in a Historically Minoritized Community and Their Impact on Virologic Suppression in Persons with HIV.

Improved life expectancy from advances in antiretroviral therapy (ART) has been followed by a rise in comorbidities and polypharmacy in this aging population. Historically, polypharmacy has been associated with suboptimal virologic outcomes in persons with HIV, although data in the current ART era and among historically marginalized populations in the United States are limited. We measured the prevalence of comorbidities and polypharmacy, evaluating their impact on virologic suppression. This retrospective IRB-approved cross-sectional study reviewed health records of adults with HIV on ART and receiving care (≥2 visits) in 2019 at a single center in a historically minoritized community. Virologic suppression (HIV RNA <200 copies/mL) based on polypharmacy (≥5 non-HIV medications) or multimorbidity (≥2 chronic conditions) was evaluated. Logistic regression analyses were performed to identify factors associated with virologic suppression, with age, race/ethnicity, and CD4 < 200 cells/mm3 as covariates. Of the 963 individuals that met the criteria, 67%, 47%, and 34% had ≥1 comorbidity, multimorbidity, and polypharmacy, respectively. The cohort demographics were: mean of 49 years (range, 18-81), 40% cisgender women, 46% Latinx individuals, 45% Black individuals, 8% White individuals. Virologic suppression rates were 95% among patients with polypharmacy compared with 86% in those with a lower pill burden (p = 0.0001). The odds of virologic success were higher for individuals with polypharmacy [adjusted odds ratio, aOR = 2.3 (95% confidence interval, CI: 1.2-4.4)] and Latinx identity [aOR = 2.4 (95% CI: 1.5-3.8)], but lower if a CD4 count <200 cells/mm3 [aOR = 0.07 (95% CI: 0.04-0.1)]. The comorbidity burden was higher than previously described, which are driving polypharmacy rates. In the current ART era, polypharmacy is not inherently associated with worse virologic outcomes.

Evaluation of Statin Prescribing Practices and Predictors of Statin Underutilization in Persons With HIV.

BACKGROUND: Persons with HIV (PWH) have an increased risk of cardiovascular disease (CVD) compared with those without HIV. Despite the increased risk, PWH are less likely to be prescribed statin therapy compared with the general population. The purpose of this study is to describe the statin prescribing practices of an outpatient HIV clinic and identify potential predictors of statin underutilization. METHODS: This study was a retrospective, single-center chart review of PWH ages 40-79 years receiving care at an HIV clinic. Statin eligibility, statin prescribing practices, and appropriateness of statin therapy were evaluated. Logistical regression analyses were conducted to assess for predictors of underutilization of statin therapy. RESULTS: Of the 606 patients, statin therapy was indicated in 362 patients (60%). Among those with a statin indication, 60.2% were prescribed appropriate statin therapy, 11.6% were prescribed statin therapy but not at the indicated intensity, and 28.2% were not prescribed statin therapy. Tobacco use ( P = 0.0023) was identified as a predictor of statin underutilization. The odds of statin prescribing were higher for those with clinical atherosclerotic CVD ( P = 0.004) and hypertension ( P = 0.017). CONCLUSION: Statin underutilization was significantly higher in PWH smoking tobacco and PWH without atherosclerotic CVD or low-density lipoprotein-cholesterol 190 mg/dL or higher. In addition, this study highlights the need for more robust CVD prevention efforts in PWH. Identifying predictors of statin underutilization may aid in elucidating where gaps in cardiovascular prevention care may exist.

Readmission Rates of Patients Discharged on Antipsychotic Polypharmacy Compared to Antipsychotic Monotherapy.

Antipsychotic medications are used to treat many psychiatric conditions and are paramount for relapse prevention in patients with mental illnesses. Antipsychotic monotherapy (APM) is a commonly recommended approach, however there is no clear consensus on the use of antipsychotic polypharmacy (APP). A single-center retrospective review was conducted comparing readmission rates of behavioral health patients discharged on APP or APM between August 1st 2019 and July 31st 2021. The primary outcome was the one-year psychiatric readmission rate. Secondary outcomes included further readmission time frame stratification, olanzapine equivalent doses, and use of anticholinergic medications. The total readmission rate was 24.5% (24/98) in the APP group compared to 19.1% (107/560) in the APM group (p = 0.22). Patients discharged on APM were not found to have a statistically significant increase in readmission rate compared to patients discharged on APP. Further research is needed to assess the risks and benefits of APP.

The Racial Divide: A Follow Up Study on Racial Disparity Amongst COVID-19 Survivors in an Urban Community.

Background: Studies have shown that COVID-19 has had a disproportionate effect on minority groups in both the clinical and social settings in America. We conducted a follow up study on patients previously diagnosed with COVID-19 one year ago in an urban community in New Jersey. The purpose of the study was to evaluate the socioeconomic impact of COVID-19 as well as assess for receptiveness towards COVID-19 vaccination amongst various ethnic groups. Methods: This was a prospective cohort study consisting of patients who had recovered from COVID-19 one year prior. The patients included in the study had a confirmed COVID-19 diagnosis in the months of March and April of 2020. This was a single institutional study conducted at St. Joseph's University Medical Center in Paterson, NJ from the months of March to April of 2021. Patients included in the study were either male or female aged 18 years or older. Patients who met criteria for inclusion were contacted by telephone to participate in a telephone survey. After informed consent was obtained, the patients completed a survey which obtained sociodemographic information pertaining to their diagnosis with COVID-19. Statistical analysis was performed using chi-square testing and multivariable logistic regression analysis. Results: Of the 170 patients enrolled in the study, the most common ethnicity was Hispanic (79/170 [46.47%]), followed by African American (46/170 [27.05%]). The gender distribution was 83 male (83/170 [48.82%]) and 87 female (87/170 [51.18%]) with a mean age of 51.5. Caucasians were the most willing to receive a COVID-19 vaccine (28/30 [93.3%]), followed by Asians (13/14 [92.8%]), Hispanics (63/78 [80.7%]) and African Americans (29/46 [63.0%]). Hispanics had the highest rate of job loss (31/79 [39.24%]), followed by of African Americans (16/46 [34.7%]). Hispanics were found to be in the most financial distress (31/79 [39.2%]), followed by African Americans (17/46 [36.9%]). Chi square analysis revealed Hispanics and African Americans were more likely to lose their jobs after being diagnosed with COVID-19 (p: 0.04). Hispanics and African Americans were also more likely to refuse vaccination with any of the available COVID-19 vaccines (p: 0.02). Multivariable Logistic regression analysis was then performed comparing both Hispanics and African Americans to Caucasians. Hispanics were more likely to lose their jobs compared to Caucasians (odds ratio, 4.456; 95% CI, 1.387 to 14.312; p: 0.0121). African Americans were also more likely to lose their jobs when compared to Caucasians (odds ratio, 4.465; 95% CI, 1.266 to 15.747; p: 0.0200). Discussion: Overall Hispanics reported the highest rates of financial distress after their diagnosis with COVID-19. Nearly 40% of the Hispanic lost their jobs following their diagnosis with COVID-19 which was the highest in our study group. African Americans were similarly affected with about 37% of all patients experiencing job loss and financial distress following diagnosis with COVID-19. Hispanics and african americans were the two ethnic groups who were least willing to receive COVID-19 vaccination. Only 63% of African Americans were willing to receive the vaccine, with 80.7% of Hispanics willing to become vaccinated. The most common reason for not receiving any of the COVID-19 vaccines was due to lack of trust in the vaccine. Both Hispanics and African Americans were more statistically likely to lose their jobs as well as refuse COVID-19 vaccination following diagnosis with COVID-19.

Unveiling the relevance of traffic enforcement cameras on the severity of vehicle-pedestrian collisions in an urban environment with machine learning models.

PURPOSE: One of the leading causes of violent fatalities around the world is road traffic collisions, and pedestrians are among the most vulnerable road users with respect to such incidents. Since walking is highly promoted in urban areas to alleviate motor-vehicle externalities, it is paramount to understand the causes associated with vehicle-pedestrian collisions and their severity to provide safe environments. Although traffic enforcement cameras can address vehicle-vehicle collisions, little is known about their effectiveness with respect to vehicle-pedestrian incidents. METHODOLOGY: In this study, we trained a set of machine learning models to forecast if a vehicle-pedestrian collision will turn into an injury or fatality, and the most suitable model was used to investigate the contributing features associated with such events with emphasis on the impact of traffic enforcement cameras. In addition to traffic enforcement camera proximity, features associated with the collision, weather, vehicle, victim, and infrastructure are included in the model to reduce unobserved heterogeneity. RESULTS: Results show that a Linear Discriminant Analysis model surpasses other machine learning models considering the evaluation metrics. Results reveal that the age and gender of the victim, the involvement of larger vehicles in the collision, and the quality of the illumination are the causes associated with pedestrian fatalities. On the other hand, involvement of motorcycles and collisions that occurred in densely populated locations are the causes associated with pedestrian injuries. CONCLUSIONS: This investigation demonstrates how to articulate machine learning into a vehicle-pedestrian crash analysis to understand the direction and magnitude of covariates in the corresponding severity outcome. Furthermore, it highlights the remarkable effect that traffic enforcement cameras and other features have on vehicle-pedestrian crash severity. These results provide actionable guidance for educational campaigns, enhanced traffic engineering, and infrastructure improvements that could be implemented in the analyzed region to provide safer transportation.

Hepatitis C virus micro-elimination within a clinic for people with HIV: challenges in the home stretch.

OBJECTIVES: To describe a pharmacist-led campaign aimed at reducing the proportion of people with HIV with ongoing chronic hepatitis C virus (HCV) infection and delineating barriers to HCV care in this patient population. METHODS: An electronic report and retrospective chart review were used to identify patients who remained with HCV infections after a previous treatment initiative. A clinical pharmacist and pharmacy resident approached the remaining HCV patients during their routine visits for HIV care to offer and coordinate direct-acting antiviral (DAA) treatment. The primary end-point was to compare the prevalence of chronic HCV before and after the intervention period. Barriers to care were also evaluated, with logistic regression performed to identify predictors of sustained virologic response (SVR) attainment. RESULTS: Forty-six patients were included in the analysis (4.2% of clinic population), with HCV prevalence falling to 0.6% (six patients) by the end of the study (p < 0.0001). The HCV care cascade in the cohort was as follows: 70% agreed to and received DAA therapy, 63% initiated therapy, and 50% achieved SVR. The top barriers to care at baseline included recreational drug use (67%), poor engagement in care (61%), and mental health disorders (28%). Poor engagement in care and active recreational drug use were associated with decreased odds of achieving SVR in bivariate analysis. CONCLUSIONS: A coordinated effort can make strides towards reducing the overall burden of HCV in this challenging population. The HCV care cascade remains tied to the HIV continuum of care, with poor engagement in care remaining an important rate-limiting step impeding micro-elimination.

Clinical differentiation of inflammatory bowel disease (IBD) in Latin America and the Caribbean.

ABSTRACT: The aim of the present study was to describe the epidemiological and clinical characteristics of inflammatory bowel disease (IBD), including medical and surgical treatments, in several countries in Latin America and the Caribbean.IBD is recognized as a global health problem because its incidence and prevalence have increased significantly over the last few years.This multicenter retrospective cohort study included 4714 patients with IBD diagnosed from 9 countries in Latin America and the Caribbean: Colombia, Cuba, Dominican Republic, Ecuador, Mexico, Peru, Puerto Rico, Uruguay, and Venezuela.Crohn disease (CD) was more frequent in Puerto Rico (71.9%), the Dominican Republic (61.0%), and Peru (53.1%). Ulcerative colitis was more frequent in Colombia (78.6%), Venezuela (78.2%), Mexico (75.5%), Cuba (69.9%), Ecuador (64.1%), and Uruguay (60.9%). The following clinical characteristics were more frequent in the Caribbean: penetrating behavior in CD, steroid dependence, steroid resistance, intolerance to thiopurines, extraintestinal manifestations, surgeries, hospitalizations due to IBD, and family history of IBD. The factors associated with the use of biological therapy were pancolitis in ulcerative colitis, penetrating behavior in CD, steroid resistance and dependence, presence of extraintestinal manifestations, and the need for surgery.This study from Latin America and the Caribbean demonstrated the different epidemiological and clinical characteristics of IBD.

When Coadministration Cannot Be Avoided: Real World Experience of Direct Acting Antivirals for the Treatment of Hepatitis C Virus Infection in Patients on First Generation Anticonvulsants.

BACKGROUND: Coadministration of direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection and first generation anticonvulsants is currently not recommended due to a drug-drug interaction that could potentially lead to subtherapeutic DAA levels and subsequent treatment failure. Currently, there is limited data evaluating this interaction and timely treatment of HCV infection with DAAs is imperative to prevent liver-related morbidity and mortality. METHODS: A retrospective case series evaluating clinical cure of chronic HCV infection, defined as sustained virologic response (SVR) 12 weeks after completion of DAA therapy, in patients from three inner-city clinics who remained on first generation anticonvulsants during the treatment course. RESULTS: A total of five patients received standard dose DAAs for treatment of chronic HCV infection while being maintained on first generation anticonvulsants. The most common HCV genotype was 1a (80%), followed by 1b (20%). The majority of patients were treated with glecaprevir/pibrentasvir (80%) for eight weeks and one patient was treated with ledipasvir/sofosbuvir for 12 weeks. Anticonvulsant regimens consisted of carbamazepine, phenytoin, phenytoin plus phenobarbital, phenytoin plus levetiracetam, and phenobarbital plus lacosamide. All five patients achieved sustained virologic response (SVR) despite this drug-drug interaction. CONCLUSION: Although every effort to prevent concomitant use of DAAs and potent inducers should be made, clinical cure may still be achieved in patients whom cannot avoid this coadministration.

Pharmacists' Perceptions and Drivers of Immunization Practices for COVID-19 Vaccines: Results of a Nationwide Survey Prior to COVID-19 Vaccine Emergency Use Authorization.

BACKGROUND: Pharmacists play a vital role in recommending and providing vaccines to improve public health and are on the front line of mass immunization efforts. AIM: The objective of this study is to evaluate pharmacists' perceptions on COVID-19 vaccines prior to emergency use authorization (EUA) amid a global pandemic. METHODS: A voluntary, anonymous, cross-sectional survey was conducted between September and November 2020. Survey respondents included a convenience sample of licensed pharmacists in the United States. The primary outcomes were pharmacists' willingness to receive and recommend hypothetical COVID-19 vaccines. Covariates assessed in the survey included COVID-19 exposure or personal experience, primary pharmacy practice setting, background in training, geographic region, and prioritization of clinical data. The data were analyzed using descriptive and inferential statistics. RESULTS: This study surveyed 763 pharmacists and results from 632 participants were included in final analysis. Overall, 67.1% of the pharmacists were willing to receive a COVID-19 vaccine and 63.4% of the pharmacists were willing to recommend a COVID-19 vaccine at ≤1 year from the time of vaccine approval. At >1 year after vaccine approval, 78% of the pharmacists were willing to receive a COVID-19 vaccine and 81.2% of the pharmacists were willing to recommend a COVID-19 vaccine. CONCLUSIONS: Survey findings suggest that, while a majority of pharmacists surveyed indicate acceptance of hypothetical COVID-19 vaccines, there remains to be hesitancy among pharmacists to receive or recommend vaccination.

P015 Impact of IBD on Daily Lives: A Descriptive Insight to Patient's Experience in the Work and Study Settings.

BACKGROUND: Persons with inflammatory bowel diseases (IBD) endure the uncomfortable symptomatology of the disease, while trying to carry out daily activities. Given that IBD is not physically distinctive, it may be overlooked and lead to discrimination in the workplace and school. We aim to describe work and study experiences from patients with IBD. METHODS: A questionnaire containing sociodemographic, psychological, and medical inquiries was administered to patients with IBD in a tertiary care clinic. The survey captured past and present employment and scholarly status. Productivity was established by the number of early leaves or absences patients experienced due to disease symptomatology. Qualitative and quantitative data were analyzed using descriptive statistics. The study is approved by the UPR-MSC IRB. RESULTS: A total of 120 patients, 59 males and 61 females, with a mean age of 27.00 ± 9.71 were recruited. 91 participants had CD, while 29 had UC. 94% of subjects had some form of income. At the time of interview, 83 patients were working. 19% did not tell the employer of their IBD, while 19% felt discriminated at work due to their condition. 38% said the disease has limited their work goals. Of those working, 74 had to leave early or absent themselves due to disease manifestation. In the last year, 39% of patients had absented themselves for 1-2 days, 27% for 3-4 days, 9% for 5-6 days, 4% for 7-8 days, 3% for 9-10 days and 18% for more than 10 days. The mean of absences from work was 4.4 days. Patients with UC were significantly more prone to work absences than patients with CD (P = 0.0243). 69 patients were studying while having the condition. 67% achieved a college or higher degree, while 33% had high school or less. 34% had to drop a course during their school years. Of the 23 patients who experienced withdrawals, 74% had a total withdrawal from school, while 26% had a partial withdrawal at some point. 14% did not inform of their IBD at school, 12% felt discriminated because of their condition and 32% said the disease has limited their educational goals. 87% of those studying had to miss or leave school early due to disease manifestation. In the last year, 24% of patients had absented themselves for 1-2 days, 29% for 3-4 days, 7% for 5-6 days, 7% for 7-8 days, 3% for 9-10 days and 30% for more than 10 days. The mean of absences was 5.6 days. School absences were not significantly different between subjects with CD and UC (P = 0.384). 22% of participants deemed themselves as a person with a disability given their condition, while 8% did not know whether they should consider themselves as such. Perception of disability was not significantly different between patients with CD and UC (P = 0.870). CONCLUSION: Absenteeism is a significant factor affecting productivity in patients with IBD. Perception of disability may also impact work and study experiences. Raising awareness is essential for patient support in these settings.

Drug interaction after ritonavir discontinuation: considerations for antiretroviral therapy changes in renal transplant recipients.

Organ transplantation among people living with human immunodeficiency virus (PLHIV) is increasing. Guidelines recommend any changes in antiretroviral therapy (ART) prior to transplantation, but there are limited data regarding ART changes post transplantation. We report a case where an ART switch from a protease inhibitor-based regimen to dolutegravir plus emtricitabine/tenofovir alafenamide in a renal transplant recipient led to subtherapeutic tacrolimus concentrations and an increased serum creatinine (SCr). A workup for graft rejection was performed (including kidney biopsy and cytomegalovirus and BK virus polymerase chain reaction) following the rise in SCr, which was higher than expected from dolutegravir initiation (via organ cation transporter 2 inhibition). This case highlights the potential challenges of switching ART regimens in PLHIV post transplantation.

Evaluating the impact of an international short-term medical mission through diabetic glycemic control.

BACKGROUND: This prospective observational study evaluated the impact of a primary care-based, international, short-term medical mission's (STMM) impact on diabetes disease burden as represented through reductions in hemoglobin A1C (HbA1c). METHODS: From November 2016 to May 2017, we tracked the HbA1c's of diabetic individuals in Dajabon, Dominican Republic through care provided by Waves of Health (WOH). Participants were provided counseling, glucose monitoring equipment, a 6-month supply of anti-diabetic medications, and received a 'check-in' phone call at 3 months. HbA1c's were re-measured at 6-month follow up. We hypothesized WOH diabetic care would have a modest impact of reducing mean HbA1c by 0.5%. RESULTS: In total, 75% (n = 76) of 101 participants presented for follow-up care. Mean and median HbA1c decreased from 8.71 (SD 2.0) and 8.5% to 8.36 (SD 2.1) and 7.7%, respectively (P = 0.07). The percentage of individuals with HbA1c ≤7.5 increased by 10.4% at follow-up. The mean HbA1c decrease was 1.1%. CONCLUSIONS: Though limited by sample size, our results suggest that medical STMM's may have a clinically meaningful impact in chronic disease management when utilizing a systematic combination of education, medical therapy, clearly documented medication instructions and regular trip intervals.
