High rates of mood disorders in patients with chronic idiopathic eosinopenia

BackgroundMood disorders (MD) are multifactorial disorders. Identifying new biomarkers for the early diagnosis of MD and predicting response to treatment is currently a significant research topic. Both eosinopenia and MD are associated with increased activity of the hypothalamic-pituitary-adrenal axis. The present study, therefore, used a clear definition of chronic idiopathic eosinopenia (CIE) to determine the rate of MD in a large cohort of individuals with CIE. MethodsThis retrospective population-based, case-control study uses data of seven consecutive years from the database of Leumit Health Services (LHS) - a nationwide health maintenance organization in Israel. ResultsParticipants were 13928 LHS members with CIE and 27858 negative controls. The CIE group exhibited significantly higher rates of MD than the control group throughout the whole study period, except for atypical depressive disorder at baseline. ConclusionsCIE might be associated with a higher prevalence of MD. Further basic research should elucidate the pathophysiologic mechanisms linking CIE and MD.

Anti-Ro and anti-La seropositivity is associated with increased rates of ischemic heart disease in adults: Results from a large population-based study

Background and aimsEmerging evidence suggests an arrhythmogenic effect of Anti-Ro/SSA (anti-Ro) and anti-La/SSB (anti-La) antibodies in adults, potentially involving a subclinical intracardiac inflammatory process. Despite the established association between inflammation and ischemic heart disease (IHD), it is noteworthy that as of now no study has delved into the potential link between these antibodies and IHD. This population-based study aimed to examine the association between anti-Ro/La seropositivity and IHD in the general adult population. MethodsWe conducted a retrospective study using electronic medical records from the largest health maintenance organization in Israel. Patients with positive serology for either or both anti-Ro and anti-La antibodies were included, along with matched controls. Multivariate logistic regression models were utilized to assess the odds of IHD in seropositive patients compared to controls. ResultsAmong 17,231 seropositive patients and 84,368 controls, the rate of IHD was significantly higher in the seropositive group (9.7 % vs. 8.1 %,OR = 1.23; 95%CI 1.14–1.31; p<0.001). The association was more pronounced in younger patients [<40 years old (OR = 3.36; 95%CI 1.66–6.82; p<0.001), 40–49 years old (OR = 1.85; 95%CI 1.26–2.73; p<0.01), 50–59 years old (OR = 1.87; 95%CI 1.55–2.26; p<0.001), 60–69 years old (OR = 1.26; 95%CI 1.11–1.42; p<0.001), ≥70 years old (OR = 1.11; 95%CI 1.03–1.20; p<0.01)], as well as in patients with fewer traditional cardiovascular risk-factors (none:OR = 1.29; 95 % CI 1.09 to 1.77; p<0.01, 1–2:OR = 1.30; 95 % CI 1.19 to 1.41; p<0.001, ≥3:OR = 1.09; 95 % CI 0.99 to 1.21; p=0.076). ConclusionsOur study demonstrates for the first time a positive association between anti-Ro/La seropositivity and IHD in the general adult population, especially among younger individuals with fewer traditional cardiovascular risk factors.

Implementation of AZD7442 (Tixagevimab/Cilgavimab) COVID-19 Pre-exposure Prophylaxis (PrEP) in the Largest Health Maintenance Organization in Israel: Real-world Uptake and Sociodemographic and Clinical Characteristics Across Immunocompromised Patient Groups.

AZD7442 is a combination of two neutralizing antibodies (tixagevimab/cilgavimab) with demonstrated efficacy in reducing the risk of symptomatic coronavirus disease 2019 (COVID-19) among individuals at high risk of severe COVID-19 ≤ 6months after administration. On February 15, 2022, the Israeli Ministry of Health (IMoH) authorized the administration of 300mg AZD7442 as pre-exposure prophylaxis (PrEP) against severe acute respiratory syndrome coronavirus 2infection among immunocompromised individuals aged ≥ 12years. This study describes the real-world uptake of AZD7442 in Israel. This descriptive, observational study analyzed data from Israel's largest health maintenance organization, Clalit Health Services (CHS). Individuals were assessed for AZD7442 eligibility between February 13 and December 11, 2022, and were included if they were aged ≥ 12years, had ≥ 1year of continuous CHS membership, had≥ 1 moderate or severe immunocompromising condition, and were eligible for AZD7442 per IMoH recommendations during this time frame. Overall, 19,161 AZD7442-eligible individuals with immunocompromising conditions were identified during the study period; 2829 (14.8%) received AZD7442. A higher proportion of individuals receiving AZD7442 were older (aged ≥ 65years), male, not current smokers and residents in large cities; required more physician visits (> 50 visits); and had ≥ 1 COVID-19 hospitalization over 12months, while uptake was lowest among ultra-orthodox Jewish individuals. AZD7442 uptake was also higher among individuals with multiple comorbidities (Charlson Comorbidity Index ≥ 5), including hypertension, diabetes and chronic kidney disease. In specific immunocompromised types, AZD7442 uptake was highest among individuals with lung transplantation (41%), primary immunodeficiency (32%), bone marrow transplantation (29%) and multiple myeloma (25%) or those receiving anti-CD20 therapy (26%) and was lowest in individuals with lymphoma (8%). These results show AZD7442 uptake among the eligible population of Israel in 2022 was relatively low, at 14.8%. Uptake was generally higher among immunocompromised individuals who may be perceived to be frail or at highest risk of COVID-19 infection and complications, although at 25-41%, further improvements in uptake would be more impactful. These results also indicate there is opportunity to expand AZD7442 uptake across immunocompromised groups and ensure more equitable uptake among some other sociodemographic groups. Overall, this study will help inform and reassess future implementation strategies for vulnerable populations.

Adherence to diabetes quality indicators in primary care and all-cause mortality: A nationwide population-based historical cohort study

Background In the last three decades, much effort has been invested in measuring and improving the quality of diabetes care. We assessed the association between adherence to diabetes quality indicators and all-cause mortality in the primary care setting. Methods A nationwide, population-based, historical cohort study of all people aged 45–80 with pharmacologically-treated diabetes in 2005 (n = 222,235). Data on annual performance of quality indicators (including indicators for metabolic risk factor management and glycemic control) and vital status were retrieved from electronic medical records of the four Israeli health maintenance organizations. Cox proportional hazards and time-dependent models were used to estimate hazard ratios (HRs) for mortality by degree of adherence to quality indicators. Results During 2,000,052 person-years of follow-up, 35.8% of participants died. An inverse dose–response association between the degree of adherence and mortality was shown for most of the quality indicators. Participants who were not tested for proteinuria or did not visit an ophthalmologist during the first-5-years of follow-up had HRs of 2.60 (95%CI:2.49–2.69) and 2.09 (95%CI:2.01–2.16), respectively, compared with those who were fully adherent. In time-dependent analyses, not measuring LDL-cholesterol, blood pressure, HbA1c, or HbA1c&gt;9% were similarly associated with mortality (HRs ≈1.5). The association of uncontrolled blood pressure with mortality was modified by age, with increased mortality shown for those with controlled blood pressure at older ages (≥65 years). Conclusions Longitudinal adherence to diabetes quality indicators is associated with reduced all-cause mortality. Primary care professionals need to be supported by health care systems to perform quality indicators.

Real-world effectiveness of sodium-glucose cotransporter-2 inhibitors on the progression of chronic kidney disease in patients without diabetes, with and without albuminuria.

To examine the renal effects of sodium-glucose cotransporter-2 (SGLT2) inhibition among non-diabetic individuals with chronic kidney disease (CKD) in a real-world setting. We collected de-identified data on adults without diabetes and with an estimated glomerular filtration rate (eGFR) of 25-60 mL/min/1.73 m2, who initiated the SGLT2 inhibitors dapagliflozin or empagliflozin between September 2020 and November 2022 at Maccabi Healthcare Services, an Israeli health maintenance organization. We assessed the effects of SGLT2 inhibitors on renal function (changes in eGFR slope/time). Index date was defined as the date of the first dispensing of SGLT2 inhibitors. Annual baseline slope was calculated using all eGFR measurements during the 2 years prior to index date (median = 7 measurements), while annual follow-up slope was calculated from all evaluations during 90-900 days post index date, along with baseline measurement at index date (median = 6 measurements). Paired t tests were used to compare differences between baseline and follow-up annual slopes. Of a total of 354 participants with CKD, without diabetes, who received SGLT2 inhibitors and were followed for a median of 527 days, the mean age was 72.8 ± 11.8 years, 26% were female, and 91% used renin-angiotensin system blockade. The mean eGFR was 45.4 ± 9.5 mL/min/1.73 m2. The mean body mass index was 29.1 ± 5.4 kg/m2. During the year before index date, 146 participants (41%) had a urinary albumin to creatinine ratio (UACR) <30 mg/g, 81 (23%) had a UACR of 30-300 mg/g, 74 (21%) had a UACR >300 mg/g, and 53 (15%) had no UACR evaluation. The mean eGFR slope over time was -5.6 ± 7.7 mL/min/1.73 m2 per year at baseline, which improved to -1.7 ± 6.8 mL/min/1.73 m2 per year after SGLT2 inhibitor administration (p <0.001). This effect was independent of UACR. In a real-world study of primarily older non-diabetic adults with CKD, SGLT2 inhibition was associated with a slower rate of kidney function decline, regardless of baseline UACR level.

Is infertility more common among patients with multiple sclerosis? Implications for utilization of assisted reproductive techniques

Research questionIs fertility affected in women with multiple sclerosis (MS), and what is their usage of assisted reproductive technology (ART)? DesignData regarding multiple sclerosis and ART usage among patients with multiple sclerosis were extracted from the Israeli health maintenance organization Clalit Health Service database. Data regarding the diagnosis and treatment of multiple sclerosis, cause of infertility and use of fertility treatments were collected for all female multiple sclerosis patients aged 18–45 years between 2005 and 2021. Each patient was matched by age in a 1:10 ratio with reference women from the general population. The prevalence of infertility was compared between the two groups. Univariate and multivariate statistical tests were used to analyse the association between multiple sclerosis and fertility treatments including IVF and ovarian stimulation. ResultsDuring the study period, 1309 multiple sclerosis patients were compared with 13,090 controls from the general population matched for age. The mean age was 29 ± 7.8 years. The overall prevalence of infertility was 15.4% (202/1309) among the multiple sclerosis patients, similar to the general population (16.3%; 2129/13090) (P = 0.436). The prevalence of IVF and ovarian stimulation was similar among multiple sclerosis patients and matched controls from the general population (8.1% versus 7.2%, P = 0.240; 13.8% versus 14.3%; P = 0.624, respectively). ConclusionsThe results show similar rates of infertility and fertility treatments among multiple sclerosis patients and the general population. This provides reassurance that fertility among women with multiple sclerosis does not differ from that of women in the general population, and indicates there is no excessive usage of ART.

The Effect of Accreditation in Health Care Services: Case Study at HMO- Health Maintenance Organization in Israel

The healthcare sector is a critical component of a well-functioning society that formed any society, we can depend on it and is responsible for maintaining the health of the people, and to offer them the services they need. The nature of healthcare is such that it is a service on which the health of human beings depends and helps them to live a healthy life without suffering. Quality is something that is universally desired by individuals in every kind of product or service. However, there is no aspect of society in which quality is as essential as in healthcare because if the person has a good health he will do his best to serve his society and he will be a benefit citizen to his society and country. Poor quality of services in healthcare can be the cause of physical harm or even death for a patient. As such, the ramifications of quality are nowhere as serious as in the particular domain of medicine and healthcare.

"When everyone is responsible, no one takes responsibility": exploring pediatric physiotherapy services in Israel.

According to Israel's National Health Insurance Law (1994), the Ministry of Health is responsible for the provision of health services in the country including physiotherapy services; moreover, the Special Education Law (1988), stipulates that physiotherapy services for children with motor disabilities, as well as other allied health services, are provided by the Ministry of Education in educational settings. Thus, children with motor disabilities are entitled PT services under two different laws by two different ministries. To describe the physiotherapy services for children with motor disabilities and examine how policymakers view these services, we conducted a qualitative study including in-depth semi-structured interviews with 10 policymakers from the Ministry of Health and the Ministry of Education, and the national directors of physiotherapy services from three of the four health maintenance organizations in Israel. Study results indicate that there is an array of physiotherapy services and providers. Despite the regulation of these services for children with motor disabilities, uncertainty and lack of knowledge were found about various issues. Therefore, the thematic analysis was structured around four descriptive questions: Where do the children receive physiotherapy? Who is eligible for physiotherapy treatment and who receives treatment? What interventions do children with motor disabilities receive? Who provides therapy for children with motor disabilities? Policymakers are dubious regarding the provision of these services, questioning whether children with motor disabilities receive physiotherapy services according to their needs. In addition, the abundance of suppliers does not necessarily improve the quality of services provided to children with motor disabilities, which may ultimately harm their developmental potential.

Risk factors for recurrent acute mastoiditis in pediatric patients: a registry-based cohort study.

To describe characteristics of pediatric patients with recurrent acute mastoiditis, and to identify risk factors for this condition. A retrospective cohort study. Data based on electronic medical records of the largest Health Maintenance Organization in Israel. Children hospitalized due to acute mastoiditis during the years 2008-2018 were identified, and their diagnosis was verified. Patients with recurrent acute mastoiditis were identified and grouped, and their characteristics were outlined and compared to those of the original group to identify risk factors for recurrence. During the 11-year period, a total of 1115 cases of children hospitalized due to acute mastoiditis were identified with a weighted incidence rate of 7.8/100,000. Of this group, 57 patients were diagnosed with recurrence following a full clinical recovery. The incidence proportion of recurrent acute mastoiditis was 5.1% (57/1115), male-to-female ratio was 27:30, 73.4% were younger than 24 months, the median period from the first episode was 3.4 months (IQR 2.0;10.0), and 82.5% of the patients (n = 47) had a single recurrence, whereas 18.5% (n = 10) had two recurrences or more. Mastoidectomy and swelling over the mastoid area during the first episode were identified as the main risk factors for recurrent mastoiditis HR = 4.7 [(2.7-8.2), p < 0.001] and HR = 2.55 [(1.4-4.8), p = 0.003], respectively. Mastoidectomy was the only independent significant risk factor for recurrence in a multivariate analysis. Mastoidectomy and swelling over the mastoid area during the first episode of acute mastoiditis were found strongly related independent risk factor for future recurrent episodes of acute mastoiditis.

Short- and Long-Term Mortality of Hospitalized Patients With Autoimmune Rheumatic Diseases and Serious Infections: A National Cohort Study.

Infectious conditions are a significant cause of mortality in autoimmune rheumatic diseases (ARD). Among patients hospitalized with an infection, we compared in-hospital and long-term (3-year) mortality between those with and without ARD. This retrospective analysis included members of the largest health maintenance organization in Israel, aged > 18 years at the first episode of infection, who required hospitalization during 2003-2019. We compared in-hospital mortality and the results of a 3-year landmark analysis of those who survived the index hospitalization between patients with ARD, according to disease subgroups, and patients without ARD. Additionally, we compared mortality outcomes among patients with ARD, according to subgroup diagnosis, matched in a 1:3 ratio by age, sex, and ethnicity to patients without ARD. Included were 365,247 patients who were admitted for the first time with the diagnosis of a serious infection. Of these, we identified 9755 with rheumatoid arthritis (RA), 1351 with systemic lupus erythematosus, 2120 with spondyloarthritis (SpA), 584 with systemic sclerosis, and 3214 with vasculitis. In a matched multivariate analysis, the risk for in-hospital mortality was lower among patients with RA (odds ratio [OR] 0.89, 95% CI 0.81-0.97) and SpA (OR 0.77, 95% CI 0.63-0.94). In a similar analysis, the risk of 3-year mortality was lower among patients with RA (hazard ratio [HR] 0.82, 95% CI 0.78-0.86) and vasculitis (HR 0.86, 95% CI 0.80-0.93). Among patients hospitalized for an infection, the risk of in-hospital and 3-year mortality was not increased among those with ARD compared to those without ARD.

Large increase in ASD prevalence in Israel between 2017 and 2021.

Accurate estimation of annual changes in autism spectrum disorders (ASD) prevalence is critical for planning the expansion of diagnostic, education, and intervention services at an adequate rate. Previous studies from Israel have reported that ASD prevalence among 8-year-old children has increased from estimates of 0.3% in 2008 to 0.65% in 2015 and 1.3% in 2018. Here, we analyzed data acquired from the National Insurance Institute of Israeli (NII), a governmental organization that approves and monitors all ASD children who receive welfare services in Israel, and Clalit Health Services (CHS), the largest Health Maintenance Organization in Israel that provides health services to ~52% of the population. Data from both sources included annual data files from 2017 to 2021 containing the number of ASD cases per year of birth for 1-17-year-old children. This allowed us to estimate annual ASD prevalence among 3.5 million children born between 2000 and 2020 in Israel. Both data sources revealed a nearly two-fold increase in ASD prevalence among 1-17-year-old children from 2017 to 2021. Estimated prevalence rates differed across age groups with 2-3-year-old (day-care) children increasing from 0.27% to 1.19% (>4 fold change), 4-6-year-old (pre-school) children increasing from 0.8% to 1.83%, and 8-year-old children increasing from 0.82% to 1.56% in NII data. These results demonstrate that autism prevalence continues to increase in Israel with a shift towards diagnosis at earlier ages. These findings highlight the challenge facing health and education service providers in meeting the needs of a rapidly growing autism population.

Future diabetes risk can be predicted by the number of abnormal oral glucose tolerance test values during pregnancy.

To quantify the future risk of type 2 diabetes (T2D) in women with gestational diabetes (GD) based on baseline metabolic characteristics and the number of abnormal values during a 3-hour 100-g oral glucose tolerance test (OGTT). We conducted a population-based retrospective cohort study of 10 023 pregnant women who underwent testing for GD in a large health maintenance organization in Israel using a 100-g OGTT. Glucose values were obtained at four time points, 0, 60, 120 and 180 minutes. We identified 9939 women who met the study criteria. Median follow-up was 3.25 (interquartile range 1.5-5.1; maximum 10.1) years. Using women without GD as reference, women with GD were at an increased risk of future T2D (hazard ratio [HR] 5.33 [95% confidence interval {CI} 3.86-7.34]). This risk increased with a greater number of abnormal OGTT values, with the highest risk seen in women with four abnormal values (HR 16.67 [95% CI 7.94-35.01]). In a multivariate model, a higher number of abnormal values, Arab ethnicity, higher body mass index, triglycerides and prepregnancy glucose were significantly associated with increased risk. Future T2D risk was also affected by the type of OGTT abnormality; an abnormal fasting value had the greatest risk, whereas an abnormal 3-hour value had the lowest risk (HR 3.61 [95% CI 2.42-5.38] vs. 1.50 [95% CI 0.93-2.43], respectively). GD isa heterogenous disease, with varying degrees of glucose intolerance and subsequent T2D risk. Targeting interventions to womenat the highest risk may help to improve postpartum adherence and effective long-term follow-up strategies.

The use of digital health services and its predicting factors among health maintenance organizations

Abstract Background In line with insights whereby digital health services (DHS) can increase the accessibility and availability of health services, health maintenance organizations (HMO) have developed various DHS, with the aim of improving services and reducing disparities in health. Specifically, the COVID-19 crisis forced HMO to accelerate the use of DHS, to allow for remote health services. Yet, the implementation of technology-based services in healthcare is complex, due to a range of obstacles related to technological, ethical, and human aspects. This study aimed at identifying and comparing the predicting factors of DHS use, including digital health literacy and attitudes towards DHS, to understand its implementation among the four HMO in Israel. Methods The study included a correlative cross-sectional design. Data was gathered via a closed-end questionnaire, distributed through an online panel to 609 Israeli respondents, aged ≥20, regarding demographics and attitudes towards DHS, digital health literacy, and the extent of DHS use. Hierarchical regression was performed to examine whether the research variables predict DHS use. One-way ANOVA was conducted to compare between HMO. Results Higher use of DHS was found to be predicted by ethnicity (Jews), income (average and above), belonging to a certain HMO (Maccabi and Leumit Health Services), positive attitudes towards DHS, and higher digital health literacy (R2=.26). In addition, significant differences were seen between HMO in the degree of use (moderate effect) and attitudes towards DHS (weak effect): members of Maccabi and Leumit Health Services held more positive attitudes towards DHS, and made greater use of them, compared to members of Clalit and Meuhedet Health Services. Conclusions As use of DHS differs across HMO, the latter should act to adapt DHS to meet the characteristics and needs of certain target groups among their members, as a means for increasing the use of digital services. Key messages • HMO should adapt their DHS to meet members’ demographic characteristics and needs. • Adjusting DHS may improve members’ attitudes towards such services and increase their involvement in using them.

Adult Attention-Deficit/Hyperactivity Disorder and the Risk of Dementia

Evidence that adult attention-deficit/hyperactivity disorder (ADHD) is associated with an increased risk of dementia is scarce and inconsistent, and potential sources of bias are untested. To examine the association between adult ADHD and the risk of dementia. This prospective national cohort study consisted of 109 218 members of a nonprofit Israeli health maintenance organization born between 1933 and 1952 who entered the cohort on January 1, 2003, without an ADHD or dementia diagnosis and were followed up to February 28, 2020. Participants were aged 51 to 70 years in 2003. Statistical analysis was conducted from December 2022 to August 2023. Adult ADHD was a time-varying covariate, classified as present from the age of the first diagnosis (using the International Classification of Diseases, Ninth Revision, and the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision); otherwise, absent. Cox regression models were fitted to quantify the association between adult ADHD and the risk of incident dementia with hazard ratios (HRs) and their 95% CIs unadjusted and in the primary analysis, using inverse probability weights, adjusted for 18 sources of potential confounding. In 14 complementary analyses, subgroup and sensitivity analyses were implemented. At the beginning of the follow-up, the sample of 109 218 participants had a mean (SD) age of 57.7 (5.5) years, 56 474 participants (51.7%) were female, and 52 744 (48.3%) were male. During follow-up, 730 participants (0.7%) received a diagnosis of adult ADHD, and 7726 (7.1%) received a diagnosis of dementia. Dementia occurred among 96 of 730 participants (13.2%) with adult ADHD and 7630 of 108 488 participants (7.0%) without adult ADHD. In the primary analysis, compared with the absence of adult ADHD, the presence of adult ADHD was statistically significantly (P < .001) associated with an increased dementia risk (unadjusted HR, 3.62 [95% CI, 2.92-4.49; P < .001]; adjusted HR, 2.77 [95% CI, 2.11-3.63; P < .001]). Twelve of the 14 complementary analyses did not attenuate the conclusions based on the results of the primary analysis. There was, however, no clear increase in the risk of dementia associated with adult ADHD among those who received psychostimulant medication, and evidence of reverse causation was mild. In this cohort study of individuals born between 1933 and 1952 and followed up in old age, adult ADHD was associated with an increased risk of dementia. Policy makers, caregivers, patients, and clinicians may wish to monitor reliably for ADHD in old age.

Opioid consumption by cancer patients in an Israeli Health Maintenance Organization from 2007-2018.

Opioids are the cornerstone of therapy for cancer patients with moderate to severe pain. The objective was to characterize opioid purchases by cancer patients in Clalit Health Services (CHS), the largest Health Maintenance Organization in Israel, over the years 2007-2018. Data for all CHS cancer patients aged 18 years old and above who purchased an opioid at least once during the 12-year study period were obtained from computerized databases. The amount of opioids was converted into oral morphine equivalents (OME). 108,543 cancer patients who purchased opioids at least once were enrolled. They comprised 30.5% of the CHS purchasers of opioids in the study period. The total number of cancer patients who purchased an opioid at least once increased gradually from 13,057 in 2007 to 20,675 (58% increase) in 2018, while the annual number of CHS cancer patients increased by only 39%. The annual OME per capita increased from 753 mg in 2007 to 1,432 mg in 2018 (91% increase). In 2007 8.1% of the cancer patients purchased opioids and 9.2% in 2018. Two thirds of all cancer patients purchased opioids for three months or less, 11.9% continued for more than one year, and 5.8% for more than two years. There is a clinically non-significant increase in the rate of cancer patients purchasing opioids. About two thirds of the cancer patients purchased opioids for only three months, and 94% for up to two years. Under-treatment of cancer pain should still be of concern. While patients are prescribed higher doses, under-prescription may still be a problem..

Prevalence of neurological diseases among patients with selective IgA deficiency.

Background: There are no published epidemiologic studies with regard to the prevalence of neurologic diseases among subjects with selective immunoglobulin A (IgA) deficiency (sIgAD). Objective: To investigate the prevalence of neurologic diseases among the Israeli population with sIgAD. Methods: A population-based case-control study among members of a large nationwide health maintenance organization in Israel providing services to > 700,000 members. The sIgAD group included individuals ≥4 years of age with a serum IgA level of <0.07 g/L and with a diagnosis of sIgAD. The control group was randomly sampled from the entire study population with a case-control ratio of five controls for each case (1:5), with exact matching for age, gender, ethnic group, and socioeconomic status category. Results: A total of 796 subjects ages 20.58 ± 15.46 years; 391 female subjects (49.1%) were identified as having sIgAD. The control group was constituted of 3980 matched subjects. The sIgAD group was characterized by a higher prevalence of autism spectrum disorder and tic disorders. Migraine was less prevalent in the sIgAD group (19 [2.39%]) than in the control group (168 [4.22%]), odds ratio (OR) 0.55 (95% confidence interval {CI}, 0.34-0.90); p = 0.016]. More cases of subjects with epilepsy were observed in the sIgAD group (14 [1.76%]) than in the control group (31 [0.80%]), OR 2.28 (95% CI, 1.12 - 4.44; p = 0.015). Conclusion: Our observation raises the question of the role of IgA in noninfectious diseases of the central nervous system. Further basic studies are needed to explain our observation.

A Nationwide Digital Multidisciplinary Intervention Aimed at Promoting Pneumococcal Vaccination in Immunocompromised Patients.

Immunocompromised patients (IPs) are at high risk for infections, some of which are vaccine-preventable. The Israeli Ministry of Health recommends pneumococcal conjugate vaccine 13 (PCV13) and pneumococcal polysaccharide vaccine 23 (PPSV23) for IP, but vaccine coverage is suboptimal. We assessed the project's effectiveness in improving the pneumococcal vaccination rate among IP. An automated population-based registry of IP was developed and validated at Maccabi Healthcare Services, an Israeli health maintenance organization serving over 2.6 million members. Included were transplant recipients, patients with asplenia, HIV or advanced kidney disease; or those receiving immunosuppressive therapy. A personalized electronic medical record alert was activated reminding clinicians to consider vaccination during IP encounters. Later, IP were invited to get vaccinated via their electronic patient health record. Pre- and post-intervention vaccination rates were compared. Between October 2019 and October 2021, overall PCV13 vaccination rates among 32,637 IP went up from 11.9% (n = 3882) to 52% (n = 16,955) (p < 0.0001). The PPSV23 vaccination rate went up from 39.4% (12,857) to 57.1% (18,652) (p < 0.0001). In conclusion, implementation of targeted automated patient- and clinician-facing alerts, a remarkable increase in pneumococcal vaccine uptake was observed among IP. The outlined approach may be applied to increase vaccination uptake in large health organizations.

Real-World Data of Adherence and Drug Survival of Biologics in Treatment-Naïve and Treatment-experienced Adult Patients with Rheumatoid Arthritis.

Biologic disease-modifying anti-rheumatics drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) are important treatments for rheumatoid arthritis (RA). As more of these drugs become available, there is a greater need to assess their real-world adherence and drug survival. Treatment-naïve and treatment-experienced patients with RA who initiated treatment with bDMARDs and tofactinib during 2015-2018 in a large Israeli health maintenance organization were included. Adherence and time to treatment suspension were recorded. Odds for adherence were estimated using a multivariable logistic regression model. Risk for treatment suspension was estimated using a mixed-effect Cox proportional hazard model. The analysis included 753 eligible patients (61.8% treatment-naïve) treated with 1287 treatment episodes (tofacitinib 24.2%, tocilizumab 17.5%, etanercept 16.0%, adalimumab 10.4%, abatacept 9.9%, rituximab 9.0%, golimumab 6.9%, certolizumab pegol 3.6%, infliximab 1.9%, and sarilumab 0.5%). Good adherence was measured for almost all drugs, yet over 50% of all treatment episodes were suspended. Older age was associated with reduced risk for treatment suspension while higher number of primary care visits and higher Charlson's comorbidity score were associated with increased risk. Compared to etanercept, treatment with adalimumab, certolizumab, or rituximab was associated with increased risk for treatment suspension (HR 1.68 95% CI 1.27-2.22, HR 1.62 95% CI 1.00-2.60, and HR 2.72 95% CI 2.02-3.67, respectively). Treatment choice primarily depends on disease activity and prognosis. Real-world data, showing differences in drug survival of bDMARDs and tsDMARD, can also be used in the variety of considerations when choosing treatment. Future studies could separate patients with RA into subgroups, which would also account for potential drug survival differences and enable personalized therapy.

Colorectal cancer among inflammatory bowel disease patients: risk factors and prevalence compared to the general population.

Colorectal cancer (CRC) is a feared complication of inflammatory bowel disease (IBD). We aimed to investigate the prevalence and risk factors of CRC among a large cohort of IBD patients. Data on IBD patients free of CRC at baseline was extracted using the MDClone platform of the Clalit health maintenance organization in Israel. We investigated the frequency rate of CRC among IBD patients compared to a control group without IBD. Possible risk factors, including comorbidities and IBD-related medications, were investigated in a multivariate analysis. During a follow-up of 139,448 years among Crohn's disease (CD) patients and 139,533 years among ulcerative colitis (UC) patients, a frequency rate of CRC was 1.5% (191) among 12,888 CD patients and 2.1% (261) among 12,381 UC patients compared to 1.2% among 57,334 controls. In a multivariate analysis of UC patients, age at diagnosis (OR 1.030, p < 0.001), primary sclerosing cholangitis (OR 2.487, p = 0.005), diabetes mellitus (OR 2.01, p < 0.001), and glucocorticoids treatment (OR 1.465, p = 0.008) were found to be predictors of CRC. For CD patients, age at diagnosis (OR 1.035, p < 0.001), primary sclerosing cholangitis (OR 2.25, p = 0.029), and glucocorticoids treatment (OR 2.07, p < 0.001) were found to be predictors for CRC, but not diabetes mellitus. Despite the continuously decreasing rates of CRC among IBD patients, these are still higher in IBD patients compared to the general population. IBD patients, particularly those with risk factors, require special consideration in follow-up for CRC.

Different effects of chronic omeprazole use on osteoporotic fractures rate in the elderly.

To investigate the potential association of chronic use of omeprazole with the occurrence of osteoporotic fractures (OF) in community-dwelling elderly subjects. The cohort consisted of community-dwelling residents aged >65 years registered with a large health maintenance organization in Israel between January 2002 and December 2016. Data were retrospectively collected from the electronic medical files on demographics, parameters known to be associated with OF, diagnoses of osteoporotic hip, wrist, and vertebral fractures, and chronic use of omeprazole (>11 prescriptions/year). Time to OF/death/end of study was calculated from the beginning of the study (2002). The risk of fractures in the chronic users of omeprazole was analyzed by multivariate Cox proportional hazard regression model. In total, 46 805 subjects were included (41% men), mean age 83.4±6.4 years, of whom 10 272 (21.9%) were chronic users of omeprazole. During 14 years of follow-up, OF were diagnosed in 414 (4.0%) omeprazole users and 1007 (2.8%) omeprazole nonusers (p < 0.001). In a Cox regression model adjusted for age and gender only, chronic use of omeprazole was associated with a 16% excess of OF. However, when parameters known to be associated with OF were entered into the multivariate Cox regression model, chronic use of omeprazole was not found to be an independent risk factor for OF, either overall (adjusted hazard ratio = 0.965, 95% confidence interval 0.86-1.08, P = .55) or specifically, in the ≥85 years age group (adjusted hazard ration = 0.780, 95% confidence interval 0.635-0.958, P < .05) in which an inverse correlation between omeprazole use and OF, was demonstrated. Chronic use of omeprazole was not associated with the occurrence of OF in elders.
