Blepharoptosis and cognitive performance: a population-based study of 1.4 million adolescents.

The purpose of this study is to examine the association between blepharoptosis and cognitive performance in late adolescence. This population-based, retrospective, cross-sectional study included 1,411,570 Israeli-born adolescents (620,107 women, 43.9%) aged 16-19 years who were medically examined before compulsory military service between 1993 and 2017. The diagnosis of blepharoptosis was verified by an ophthalmologist. Cognitive performance was assessed by a validated intelligence-quotient-equivalent test, comprising four domains (problem-solving, verbal abstraction and categorization, verbal comprehension, and mathematical abilities). Cognitive Z-scores were calculated and categorized as high (≥ 1 standard deviation (SD)), medium (- 1 to < 1 SD), and low (less than - 1 SD). Relationships were analyzed using regression models adjusted for sociodemographic variables including sex, year of birth, residential socioeconomic status, education level, body mass index, and familial country of origin. A total of 577 (41 per 100,000, 32.2% women) adolescents were diagnosed with blepharoptosis. The proportions of unilateral and bilateral visual impairment among adolescents with blepharoptosis were 13.0% and 3.5%, respectively. In a multivariable analysis, blepharoptosis was associated with a 0.18 SD reduction in cognitive Z-score (p < 0.001). The adjusted odds ratios for low and high cognitive Z-scores in adolescents with blepharoptosis were 1.54 (1.25-1.89) and 0.80 (0.62-1.04), respectively. This relationship persisted when adolescents with normal best-corrected visual acuity or unimpaired health status were analyzed separately.  Conclusions: Blepharoptosis is associated with reduced cognitive performance determined in late adolescence. Future prospective studies should investigate the causes of this link and their underlying mechanisms. What is Known: • While earlier investigations have examined the effects of blepharoptosis on vision and quality of life, the association between blepharoptosis and cognitive outcomes in youth has remained unexplored. What is New: • This nationwide study involving 1.4 million Israeli adolescents found a correlation between blepharoptosis and reduced cognitive performance. • Our findings suggest a potential interplay between blepharoptosis and cognitive development in the pediatric population, calling for increased focus on the educational needs of affected individuals.

Racial/ethnic and socioeconomic disparities in colorectal cancer screening in a large organization with universal insurance before and during the coronavirus disease 2019 pandemic.

OBJECTIVES: Israel is regarded as a country with a developed economy and a moderate income inequality index. In this population-based study, we aimed to measure the inequalities in colorectal cancer screening within Clalit Health, an organization with universal insurance, before and during the coronavirus disease 2019 pandemic. SETTING: Retrospective analysis within Clalit Health Services, Israel. METHODS: We evaluated the rate of being up to date with screening (having a colonoscopy within 10 years or a fecal occult blood test within 1 year) and the colonoscopy completion rate (having a colonoscopy within 6 months of a positive fecal occult blood test) among subjects aged 50-75 in 2019-2021. RESULTS: In 2019, out of 918,135 subjects, 61.3% were up to date with screening; high socioeconomic status: 65.9% (referent), medium-socioeconomic status: 60.1% (odds ratio 0.81, 95% confidence interval 0.80-0.82), low-socioeconomic status: 59.0% (odds ratio 0.75, 95% confidence interval 0.74-0.75); Jews: 61.9% (referent), Arabs: 59.7% (odds ratio 0.91, 95% confidence interval 0.90-0.92), Ultraorthodox-Jews: 51.7% (odds ratio 0.77, 95% confidence interval 0.75-0.78). Out of 21,308 with a positive fecal occult blood test, the colonoscopy completion rate was 51.8%; high-socioeconomic status: 59.8% (referent), medium-socioeconomic status: 54.1% (odds ratio 0.79, 95% confidence interval 0.73-0.86), low-socioeconomic status: 45.5% (odds ratio 0.60, 95% confidence interval 0.56-0.65); Jews: 54.7% (referent), Ultraorthodox-Jews: 51.4% (odds ratio 0.91, 95% confidence interval 0.90-0.92), Arabs: 44.7% (odds ratio 0.77, 95% confidence interval 0.75-0.78). In 2020-2021, there was a slight drop in the rate of being up to date with screening, while most of the discrepancies were kept or slightly increased with time. CONCLUSIONS: We report significant inequalities in colorectal cancer screening before and during the coronavirus disease 2019 pandemic in Israel, despite a declared policy of equality and universal insurance.

A history of asthma is associated with susceptibility to hidradenitis suppurativa: a population-based longitudinal study.

The association of hidradenitis suppurativa (HS) and asthma remains to be investigated. To assess the bidirectional association between HS and asthma. A population-based study was conducted to compare HS patients (n = 6779) with age-, sex-, and ethnicity-matched control subjects (n = 33,259) with regard to the incidence of new onset and the prevalence of preexisting asthma. Adjusted hazard ratios (HRs) and adjusted odds ratios (ORs) were calculated. The prevalence of preexisting asthma was higher in patients with HS relative to controls (9.6% vs. 6.9%, respectively; P < 0.001). The odds of HS were 1.4-fold greater in patients with a history of asthma (fully adjusted OR 1.41; 95% CI 1.27-1.55; P < 0.001). The incidence rate of new-onset asthma was estimated at 9.0 (95% CI 6.3-12.7) and 6.2 (95% CI 5.1-7.5) cases per 10,000 person-years among patients with HS and controls, respectively. The risk of asthma was not statistically different in patients with HS and controls (fully adjusted HR 1.53; 95% CI 0.98-2.38; P = 0.062). Relative to other patients with HS, those with HS and comorbid asthma were younger at the onset of HS (30.7 [14.7] vs. 33.3 [15.1], respectively; P < 0.001) and had a comparable risk of all-cause mortality (adjusted HR 0.86; 95% CI 0.44-1.68; P = 0.660). A history of asthma confers susceptibility to subsequent development of HS. This observation is of importance for clinicians managing both patients with HS and asthma. Further research is warranted to elucidate the pathomechanism underlying this finding.

Correlates of protection for booster doses of the SARS-CoV-2 vaccine BNT162b2.

Vaccination, especially with multiple doses, provides substantial population-level protection against COVID-19, but emerging variants of concern (VOC) and waning immunity represent significant risks at the individual level. Here we identify correlates of protection (COP) in a multicenter prospective study following 607 healthy individuals who received three doses of the Pfizer-BNT162b2 vaccine approximately six months prior to enrollment. We compared 242 individuals who received a fourth dose to 365 who did not. Within 90 days of enrollment, 239 individuals contracted COVID-19, 45% of the 3-dose group and 30% of the four-dose group. The fourth dose elicited a significant rise in antibody binding and neutralizing titers against multiple VOCs reducing the risk of symptomatic infection by 37% [95%CI, 15%-54%]. However, a group of individuals, characterized by low baseline titers of binding antibodies, remained susceptible to infection despite significantly increased neutralizing antibody titers upon boosting. A combination of reduced IgG levels to RBD mutants and reduced VOC-recognizing IgA antibodies represented the strongest COP in both the 3-dose group (HR = 6.34, p = 0.008) and four-dose group (HR = 8.14, p = 0.018). We validated our findings in an independent second cohort. In summary combination IgA and IgG baseline binding antibody levels may identify individuals most at risk from future infections.

The risk of retinal vein occlusion among patients with neovascular age related macular degeneration: a large-scale cohort study.

PURPOSE: To examine the risk for retinal-vein-occlusion (RVO) in patients with neovascular age-related-macular-degeneration (AMD) as compared to age- and sex-matched controls. METHOD: This is a population-based, cohort study. The study encompassed 24,578 consecutive patients with neovascular AMD and 66,129 control subjects. Multivariate cox regression analysis was utilized to detect the risk of RVO among patients with neovascular AMD. Predictors of RVO in patients with neovascular AMD were identified using multivariate logistic regression analysis. Mortality of patients was assessed using Kaplan-Meier method. RESULTS: The incidence rate of RVO was estimated at 1.25 (95% CI, 1.06-1.45) per 1000 person-years among patients with neovascular AMD and 0.25 (95% CI, 0.20-0.31) per 1000 person-years among controls. Patients with neovascular AMD were associated with an increased risk of RVO (adjusted HR, 4.35; 95% CI, 3.34-5.66; P < 0.001). Among patients with neovascular AMD, older age (≥79.0 years) was associated with a decreased risk of RVO (adjusted OR, 0.50; 95% CI, 0.37-0.70; P < 0.001), whilst a history of glaucoma increased the likelihood of RVO (adjusted OR, 2.66; 95% CI, 1.94-3.65; P < 0.001). Patients with neovascular AMD and comorbid RVO had a comparable risk of all-cause mortality relative to other patients with neovascular AMD (HR, 0.90; 95% CI, 0.67-1.22; P = 0.500) CONCLUSIONS: An increased risk of RVO was found among patients with neovascular AMD. Younger age and glaucoma predicted the development of RVO in patients with neovascular AMD. Awareness of this comorbidity is of benefit for clinicians as patients with neovascular AMD might be carefully examined for RVO signs and complications.

COVID-19 Morbidity Among Individuals with Autistic Spectrum Disorder: A Matched Controlled Population-Based Study.

In this study we aimed to assess whether individuals with ASD are prone to higher infection rates, or to severe COVID-19 illness. Individuals with ASD and age- and gender-matched controlled counterparts (total n = 32,812) were assessed for COVID-19 infection rates and hospitalizations. Results indicated higher infection rates among individuals with ASD, with the largest effect among individuals aged 40-60 (OR = 2.05, 95%CI 1.33-3.15, p < .001), as well as higher odds for hospitalizations, evident primarily in men (OR = 2.40, 95%CI 1.14-5.02, p = 0.02) but not women. Medical and environmental risk factors may associate ASD with higher infection and morbidity rates. Healthcare policy providers should consider proactive steps to protect this population from the associated risks.

Anxiety in Patients with Neovascular Age-related Macular Degeneration.

PURPOSE: The main objective of the study is to investigate the prevalence of anxiety in patients with neovascular age-related macular degeneration (nAMD). METHODS: A retrospective cross-sectional study of 3 304 nAMD patients and 16 515 age- and gender-matched controls. The proportions of patients with anxiety were compared between the groups using univariate analyses and a multivariate logistic regression model. Proportion of anxiety in patients with nAMD was compared with the proportion of anxiety in controls, matched for age and gender. Data was obtained from the largest health maintenance organization in Israel (Clalit Health Services) with 4 200 000 members. RESULTS: The mean age of patients was 79.7 years; 54.8% were females; Anxiety was more common in patients with nAMD (13.2%) compared to the control group (10.2%) (OR 1.3; 95%CI 1.2-1.5). Multivariate logistic regression analysis revealed a significant association between anxiety and nAMD (OR 1.3; 95% CI: 1.2-1.5), adjusted for age, gender, and socio-economic status. CONCLUSION: Our study demonstrated that anxiety is more common in patients with nAMD compared to a control group. Physicians treating patients with nAMD should be aware of this association, in order to provide appropriate care for the anxiety associated with nAMD.

Dipeptidyl-peptidase IV inhibitor (DPP4i) confers increased odds of bullous pemphigoid even years after drug initiation.

The timing pattern in which dipeptidyl-peptidase IV inhibitors (DPP4i) confer the risk of bullous pemphigoid (BP) is unknown. To investigate the odds of BP following exposure to DPP4i and to perform a duration-response analysis evaluating the risk of BP in relation to the duration of exposure to the culprit drug. A population-based nested case-control study was performed comparing diabetic patients with BP (n = 1458) with age-, sex- and ethnicity-matched diabetic control subjects (n = 6051) with respect to the prevalence of exposure to DPP4i. Adjusted odds ratios (ORs) were estimated by logistic regression. Overall exposure to DPP4i was associated with an 80% increase in the odds of subsequent BP (OR, 1.81; 95% CI, 1.46-2.08; P < 0.001). In an intraclass analysis, the odds of BP were increased in association with vildagliptin (OR, 3.40; 95% CI, 2.69-4.29; P < 0.001) and sitagliptin (OR, 1.56; 95% CI, 1.33-1.84; P < 0.001). In a duration-response analysis, the highest likelihood of BP was found 1-2 years after commencing the drug (OR, 2.66; 95% CI, 1.97-3.59; P < 0.001). The odds of BP were increased across all time periods and retained its statistical significance even ≥ 6 years after the drug initiation (OR, 1.44; 95% CI, 1.09-1.91; P = 0.011). Relative to other diabetic patients with BP, patients with DPP4i-associated BP were more likely to be admitted to inpatient dermatologic wards (OR, 1.66; 95% CI, 1.30-2.13; P < 0.001) and had higher mean(SD) numbers of outpatient dermatologist visits (14.7[14.8] vs. 12.3[13.2], respectively; P = 0.006). DPP4i should be suspected as a predisposing factor for BP even numerous years after the drug initiation.

Investigating the epidemiological relationship between vitiligo and psoriasis: a population-based study.

BACKGROUND: The association of vitiligo with psoriasis is inconsistent in the current literature. OBJECTIVE: To assess the bidirectional association between vitiligo and psoriasis. METHODS: A population-based study was performed to compare vitiligo patients (n = 20,851) with age-, sex- and ethnicity-matched control subjects (n = 102,475) regarding the incidence of new-onset and the prevalence of preexisting psoriasis. Adjusted hazard ratios (HRs) and adjusted odds ratios (ORs) were calculated by cox regression and logistic regression, respectively. RESULTS: The incidence rate of new-onset psoriasis was estimated at 7.9 (95% CI 6.4-9.7) and 4.7 (95% CI 4.1-5.3) cases per 10,000 person-years among patients with vitiligo and controls, respectively. Patients with vitiligo experienced an increased risk of psoriasis (fully-adjusted HR 1.71; 95% CI 1.35-2.17; P < 0.001). On the other hand, the odds of vitiligo were only marginally elevated among patients with preexisting psoriasis (fully-adjusted OR 1.19; 95% CI 1.01-1.40; P = 0.051). Compared to other patients with vitiligo, those with vitiligo and comorbid psoriasis were older at the onset of the disease and had a greater prevalence of metabolic and cardiovascular comorbidities. CONCLUSIONS: A diagnosis of vitiligo predisposes individuals to develop subsequent psoriasis. Clinicians managing dermatologic patients ought to be aware of this comorbidity. Further research is required to explicate the pathomechanism underlying this epidemiological observation.

The association of uveitis with hepatitis B and hepatitis C viruses: a large-scale population-based study.

PURPOSE: To examine the association of uveitis with hepatitis B (HBV) and hepatitis C (HCV) chronic infections METHOD: This is a population-based cross-sectional study. The study encompassed 13,183 consecutive patients with uveitis and 65,331control subjects. The prevalence of chronic HBV and HCV infections was compared between patients diagnosed with uveitis and age-, sex-, and ethnicity-matched controls. Lifetime prevalence rates of HBV and HCV were calculated for patients with uveitis and control individuals. Odds ratio (OR) for HBV and HCV was evaluated across different strata. RESULTS: The lifetime prevalence rate of chronic HBV infection was greater in patients with uveitis than in controls (1.2% vs. 0.8%, respectively; P < 0.001). The association of HBV with uveitis was statistically significant among individuals older than 40 years of age, both sexes, and individuals of Jewish ethnicity. The lifetime prevalence of HCV was comparable between patients with uveitis and controls (0.8% vs. 0.7%, respectively; P = 0.189). Thus, no independently significant association was found between uveitis and HCV (fully-adjusted OR, 1.15; 95% CI, 0.93-1.42; P = 0.211). CONCLUSIONS: Uveitis is associated with HBV. The association was more prominent among older and Jewish patients. Patients with uveitis may benefit from screening for HBV. An association between uveitis and HCV has not been found.

Nineteen months into the pandemic, what have we learned about COVID-19-related outcomes in patients with psoriasis?

BACKGROUND: The impact of psoriasis on the outcomes of Coronavirus disease 2019 (COVID-19) is yet to be precisely delineated. OBJECTIVES: To assess the risk of COVID-19, COVID-19-associated hospitalization, and mortality among patients with psoriasis as compared with age-, sex-, and ethnicity-matched control subjects. In addition, we aim to delineate determinants of COVID-19-associated hospitalization and mortality in patients with psoriasis. METHODS: A population-based retrospective cohort study was performed to longitudinally follow patients with psoriasis and their matched controls with regard to COVID-19-related outcomes. The risk of COVID-19 infection, COVID-19-associated hospitalization, and mortality were assessed using uni- and multi-variable Cox regression analyses. Determinants of COVID-19-associated hospitalization and mortality were evaluated using multivariable logistic regression analysis. RESULTS: The study population included 144 304 patients with psoriasis and 144 304 age- and sex-matched control individuals. Patients with psoriasis displayed a slightly elevated risk of SARS-CoV-2 infection (fully-adjusted HR, 1.05; 95% CI, 1.03-1.08; p < 0.001). Relative to controls, patients with psoriasis had comparable multivariate risk of COVID-19-associated hospitalization (fully-adjusted HR, 1.08; 95% CI, 0.99-1.18; p = 0.065) and COVID-19-associated mortality (fully-adjusted HR, 0.88; 95% CI, 0.73-1.05; p = 0.162). When evaluating individuals hospitalized due to COVID-19, patients with psoriasis were more likely to have type-2 diabetes mellitus (adjusted OR, 1.24; 95% CI, 1.03-1.50; p = 0.027) and obesity (adjusted OR, 1.37; 95% CI, 1.13-1.65; p = 0.001) relative to controls. CONCLUSIONS: While patients with psoriasis are at a higher risk of contracting SARS-CoV-2 infection, they are not more susceptible to the complications of COVID-19.

COVID-19 Booster Vaccination Among Individuals With Schizophrenia in Israel.

Importance: Individuals with schizophrenia are at higher risk for severe COVID-19 illness and mortality. Previous reports have demonstrated vaccination gaps among this high-risk population; however, it is unclear whether these gaps have continued to manifest with the booster dose. Objective: To assess gaps in first, second, and booster vaccinations among individuals with schizophrenia. Design, Setting, and Participants: This was a matched, controlled, retrospective cohort study conducted in November 2021, and included follow-up data from March 2020, to November 2021. The study used the databases of Clalit Health Services, the largest health care management organization in Israel. Individuals with a diagnosis of schizophrenia at the onset of the pandemic and matched controls were included in the analysis. Main Outcomes and Measures: Rates of first, second, and booster vaccinations and time to reach vaccination. Results: The study included 34 797 individuals (mean [SD] age, 50.8 [16.4] years; 20 851 men [59.9%]) with schizophrenia and 34 797 matched controls (mean [SD] age, 50.7 [16.4] years; 20 851 men [59.9]) for a total of 69 594 individuals. A total of 6845 of 33 045 individuals (20.7%) with schizophrenia were completely unvaccinated, compared with 4986 of 34 366 (14.5%) in the control group (odds ratio [OR], 0.65; 95% CI, 0.62-0.67, P < .001). Once vaccinated, no significant differences were observed in the uptake of the second vaccine. Gaps emerged again with the booster vaccine, with 18 469 individuals (74.7%) with schizophrenia completing the booster, compared with 21 563 (77.9%) in the control group (OR, 0.83; 95% CI, 0.80-0.87, P < .001). Kaplan-Meier analyses indicated significant differences in time to reach vaccination, although gaps were lower compared with those reported in the first vaccination (log-rank test, 601.99 days; P < .001 for the first vaccination, compared with log-rank test, 81.48 days, P < .001 for the booster). Multivariate Cox regression analyses indicated that gaps in the first and booster vaccine were sustained even after controlling for demographic and clinical variables (first vaccine: hazard ratio [HR], 0.80; 95% CI, 0.78-0.81; P < .001 and booster: HR, 0.88; 95% CI, 0.87-0.90; P < .001) but were not significant for the second vaccine. Conclusions and Relevance: Results of this cohort study of Israeli adults found lower rates of COVID-19 vaccination among individuals with schizophrenia compared with a control group without schizophrenia, especially during the vaccine initiation phase. Countries worldwide should adopt strategies to mitigate the persistence of vaccination gaps to improve health care for this vulnerable population.

Determinants and Effectiveness of BNT162b2 mRNA Vaccination Among Patients with Atopic Dermatitis: A Population-Based Study.

BACKGROUND: The effectiveness of messenger RNA coronavirus disease 2019 (COVID-19) vaccines in patients with atopic dermatitis (AD) is yet to be delineated. It remains largely unknown how AD-related immunosuppressive medications affect the development of vaccine-induced immunity. OBJECTIVE: We aimed to evaluate the prevalence of the BNT162b2 messenger RNA vaccine among patients with AD and to assess its effectiveness in protecting against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, COVID-19-associated hospitalization, and mortality. A specific analysis additionally examined whether AD-related immunosuppressive drugs influenced the effectiveness of the vaccine. METHODS: A population-based cohort study was performed using the database of Clalit Heath Services, Israel, to follow adult patients with AD. Multivariate Cox and logistic regression analyses were utilized to calculate the adjusted hazard ratio (HR) and odds ratio (OR) of the incident outcomes. RESULTS: As of 26 June, 2021, 58,582 (75.4%) out of 77,682 adult patients with AD completed two BNT162b2 vaccine doses in Israel. Adulthood-onset AD (adjusted OR, 1.34; 95% CI 1.28-1.40; p < 0.001) and moderate-to-severe AD (adjusted OR, 1.13; 95% CI 1.05-1.21; p = 0.001) predicted an increased vaccination rate. Vaccinated patients with AD demonstrated a significantly decreased risk of SARS-CoV-2 infection (adjusted HR, 0.20; 95% CI 0.16-0.26; p < 0.001), COVID-19-associated hospitalization (adjusted HR, 0.08; 95% CI 0.04-0.18; p < 0.001), and COVID-19-associated mortality (adjusted HR, 0.04; 95% CI 0.01-0.20; p < 0.001). Exposure to immunosuppressive drugs (n = 597; 0.8% of patients) did not impair the protection against SARS-CoV-2 infection after vaccination (adjusted HR, 0.95; 95% CI 0.13-6.81; p = 0.958). CONCLUSIONS: In patients with AD, COVID-19 vaccination is highly effective for a wide range of COVID-19-related outcomes. Immunosuppressive drugs did not impair the effectiveness of the vaccine in preventing SARS-CoV-2 infection in this retrospective analysis.

Risk of COVID-19 and its complications in patients with atopic dermatitis undergoing dupilumab treatment-a population-based cohort study.

The risk of coronavirus disease (COVID-19) infection and its complications among patients with atopic dermatitis (AD) treated by dupilumab is yet to be determined. We aimed to assess the risk of SARS-CoV-2 infection, COVID-19-associated hospitalization, and mortality among patients with AD treated by dupilumab. A population-based cohort study was conducted to compare AD patients treated by dupilumab (n = 238) with those treated by prolonged systemic corticosteroids (≥ 3 months; n = 1,023), phototherapy (n = 461), and azathioprine or mycophenolate mofetil (MMF; n = 194) regarding the incidence of COVID-19 and its complications. The incidence rate of COVID-19, COVID-19-associated hospitalization, and mortality among patients treated by dupilumab was 70.1 (95% CI, 40.5-116.4), 5.0 (95% CI, 0.3-24.7), and 0.0 per 1,000 person-year, respectively. The use of dupilumab was not associated with an increased risk of SARS-CoV-2 infection [adjusted HR for dupilumab vs. prolonged systemic corticosteroids: 1.13 (95% CI, 0.61-2.09); dupilumab vs. phototherapy: 0.80 (95% CI, 0.42-1.53); dupilumab vs. azathioprine/MMF: 1.10 (95% CI, 0.45-2.65)]. Dupilumab was associated with a comparable risk of COVID-19-associated hospitalization [adjusted HR for dupilumab vs. prolonged systemic corticosteroids: 0.35 (95% CI, 0.05-2.71); dupilumab vs. phototherapy: 0.43 (95% CI, 0.05-3.98); dupilumab vs. azathioprine/MMF: 0.25 (95% CI, 0.02-2.74)]. When applicable, the risk of mortality was not elevated in patients with AD treated by dupilumab [HR for dupilumab vs. prolonged systemic corticosteroids: 0.04 (95% CI, 0.00-225.20)]. To conclude, dupilumab does not impose an increased risk of SARS-CoV-2 infection or COVID-19 complications in patients with AD. Dupilumab should be continued and considered as a safe drug for moderate-to-severe AD during the pandemic.

The Association of Bullous Pemphigoid With Atopic Dermatitis and Allergic Rhinitis-A Population-Based Study.

BACKGROUND: Although bullous pemphigoid (BP), atopic dermatitis (AD), and allergic rhinitis (AR) are associated with shared pathogenic mechanisms the epidemiological relationship between these conditions remains to be investigated. OBJECTIVE: To evaluate the bidirectional association of BP with AD and AR. METHODS: A population-based retrospective cohort study was performed comparing BP patients (n = 3924) with age-, sex-, and ethnicity-matched control subjects (n = 19,280), with respect to incident cases of AD and AR. A case-control design was additionally adopted to assess the odds of BP in individuals with a preexisting diagnosis of AD and AR. RESULTS: The odds of BP was increased after a preexisting diagnosis of AD (fully adjusted odds ratio, 1.76; 95% confidence interval [CI], 1.44-2.15; P < 0.001) and AR (fully adjusted odds ratio, 1.13; 95% CI, 1.01-1.28; P = 0.047). Patients with BP were at an increased risk of subsequent AD (fully adjusted hazard ratio, 2.00; 95% CI, 1.60-2.51; P < 0.001) but not AR (fully adjusted hazard ratio, 1.00; 95% CI, 0.83-1.20; P = 0.997). Compared with other patients with BP, those with BP and comorbid AD and AR were more frequently managed by adjuvant drugs and long-term systemic and topical corticosteroids and had decreased all-cause mortality. CONCLUSIONS: A history of AD and AR confers susceptibility to the development of BP. Awareness of this association may be of help for physicians managing patients with these diseases.

Risk of COVID-19 infection, hospitalization, and mortality in patients with psoriasis treated by interleukin-17 inhibitors.

BACKGROUND: The risk of the infection and its complications under this drug class remains to be determined. OBJECTIVE: To evaluate the risk of COVID-19, COVID-19-associated hospitalization, and mortality among patients with psoriasis treated by IL-17I. METHODS: A population-based cohort study was performed to compare psoriasis patients treated by IL-17I (n = 680) with those treated by methotrexate (n = 2153) and non-systemic/non-immunomodulatory treatments (n = 138,750) regarding the incidence of COVID-19 and its complications. RESULTS: The use of IL-17I was not associated with an increased risk of COVID-19 infection [adjusted HR for IL-17I vs. methotrexate: 0.91 (95% CI, 0.48-1.72); IL-17I vs. non-systemic/non-immunomodulatory treatments: 0.92 (95% CI, 0.54-1.59)]. IL-17I was associated with comparable risk of COVID-19-associated hospitalization [adjusted HR for IL-17I vs. methotrexate: 0.42 (95% CI, 0.05-3.39); IL-17I vs. non-systemic/non-immunomodulatory treatments: 0.65 (95% CI, 0.09-4.59)] and COVID-19-associated mortality [adjusted HR for IL-17I vs. methotrexate: 7.57 (95% CI, 0.36-157.36); IL-17I vs. non-systemic/non-immunomodulatory treatments: 7.05 (95% CI, 0.96-51.98)]. In a sensitivity analysis, neither secukinumab nor ixekizumab imposed an elevated risk of any of the outcomes of interests. CONCLUSIONS: IL-17I treatment does not confer an increased risk of COVID-19 infection or its complications in patients with psoriasis.

Adapting to change: Clalit's response to the COVID-19 pandemic.

The COVID-19 pandemic is the most significant global health event of the past century. The profound and unexpected changes that it brought about have forced healthcare organizations to make far-reaching adjustments to accommodate the new reality. With the outbreak of the pandemic in Israel and the understanding of its consequences, Clalit Health Services (Clalit), the largest healthcare organization in Israel, rapidly mobilized in order to provide the best response possible from the perspective of both its patients and its employees. In the short term, four designated workgroups were established just days into the pandemic. Their task was to prepare operational work plans to achieve the following goals: providing the best possible treatment for COVID patients; maintaining the level of care for non-COVID patients; protecting healthcare personnel without compromising their competence and level of functioning; and beginning the process of post-crisis planning. In the context of the long term, and with the understanding that the changes in healthcare brought about by the COVID-19 pandemic would be long-lasting and irreversible, and would act as a catalyst in Clalit's preparations for the future, Clalit has carried out the called-for modifications in its organizational strategy. This was based on the need to shift service and treatment foci from the hospitals to the community and the patient's home and his cellular device, by means of strengthening Clalit's strategic abilities to become more proactive, more digital and more home-based. In this article, we present a survey of Clalit's preparations for the new reality in the short and medium terms, as well as the leveraging of insights gained during the first wave of the pandemic, with goal of revising Clalit's long-term strategic plan. We conclude and point out the organizational abilities required for optimal response to future large-scale emergencies: The ability to quickly identify the need for change, respond quickly while harnessing the various parts of the organization in order to provide an agile and adaptive response, and facilitate long-term planning activity in parallel to providing an operational response in the short and medium terms.
