RESUMO
BACKGROUND: Collection of detailed dietary data is labor intensive and expensive, harmonization of existing data sets has been proposed as an effective tool for research questions in which individual studies are underpowered. METHODS: In this paper, we describe the methodology used to retrospectively harmonize nutritional data from multiple sources, based on the individual participant data of all available studies, which collected nutritional data in Israel between 1963 and 2014. This collaboration was established in order to study the association of red and processed meat with colorectal cancer. Two types of nutritional questionnaires, the Food Frequency Questionnaires (FFQ) and the 24-h dietary recall (24HR recall), and different food composition tables, were used by the participating studies. The main exposure of interest included type of meat (total meat, red meat, and poultry) and level of processing. RESULTS: A total of 29,560 Israeli men and women were enrolled. In studies using FFQ,the weighted mean intakes of total, red, processed meat, and poultry were 95, 27, 37 and 58 gr/day and 92, 25, 10, and 66 gr/day in studies using 24HR recall, respectively.. Despite several methodological challenges, we successfully harmonized nutritional data from the different studies. CONCLUSIONS: This paper emphasizes the significance and feasibility of harmonization of previously collected nutritional data, offering an opportunity to examine associations between a range of dietary exposures and the outcome of interest, while minimizing costs and time in epidemiological studies.

AIM: The management of type 2 diabetes mellitus has advanced in the last two decades since the introduction of glucagon-like peptide-1 receptor agonists (GLP-1RAs). However, multiple factors may interfere with achieving better glycaemic control. This study evaluated the differences between various GLP-1RAs in efficacy, adherence and persistence. MATERIALS AND METHODS: We conducted a retrospective cohort study using the electronic medical database from Clalit Health Services. Adults with type 2 diabetes mellitus who purchased any GLP-1RA between 2009 and 2021 were included. The Index Date was defined as the date of the first purchase of any GLP-1RA. We evaluated the adherence, persistence and glycaemic control after GLP-1RAs initiation. Baseline glycaemic and post-treatment glycaemic controls were analysed. RESULTS: In total, 70 654 patients were included. The mean age was 11.7 ± 60.4, and 51% were females. A significant reduction in glycated haemoglobin (HbA1c) was observed in all patients who received GLP-1RAs. However, the percentage of changes in the HbA1c was higher among weekly GLP-1RA than daily initiators (14.6% vs. 10.2%, p < 0.001). The proportion of subjects with any decrease in HbA1c was higher among the once-weekly compared with the daily dose (82.4% vs. 74.7%) and mainly patients initiated semaglutide or dulaglutide, with 16.0% and 14.7% reduction. The frequency of good adherence (the proportion of days covered ≥80%) was significantly higher among the weekly group odds ratio = 1.25 (95% confidence interval 1.21-1.28). Good adherence was reported in older age, female gender, Jewish ethnicity and high socio-economic status (p < 0.001). CONCLUSIONS: Weekly GLP-1RAs initiators were more adherent, persistent to therapy and achieved better glycaemic control. Epidemiological variables might play a role in achieving this goal.
RESUMO
In order to explore the association between meat consumption and gastrointestinal/colorectal cancer (CRC) risk and to estimate the Israeli population attributable fraction (PAF), we conducted a collaborative historical cohort study using the individual participant data of seven nutritional studies from the past 6 decades. We included healthy adult men and women who underwent a nutritional interview. Dietary assessment data, using food-frequency or 24-h recall questionnaires, were harmonized. The study file was linked to the National Cancer and death registries. Among 27,754 participants, 1216 (4.4%) were diagnosed with gastrointestinal cancers and 839 (3.0%) with CRC by the end of 2016. Using meta-analysis methods applied to Cox proportional hazard models (adjusted for daily energy intake, sex, age, ethnic origin, education and smoking),100 g/day increments in beef, red meat and poultry consumption, and 50 g/day increment in processed meat consumption were associated with hazard ratios (HRs) and 95% confidence intervals of 1.46 (1.06-2.02), 1.15 (0.87-1.52), 1.06 (0.89-1.26), and 0.93 (0.76-1.12), respectively, for CRC. Similar results were obtained for gastrointestinal cancer, although red meat consumption reached statistical significance (HR = 1.27; 95%CI: 1.02-1.58). The PAFs associated with a reduction to a maximum of 50 g/day in the consumption of red meat were 2.7% (95%CI: -1.9 to 12.0) and 5.2% (0.3-13.9) for CRC and gastrointestinal cancers, respectively. Reduction of beef consumption to a maximum of 50 g/day will result in a CRC PAF reduction of 7.5% (0.7%-24.3%). While beef consumption was associated with gastrointestinal/CRC excess risk, poultry consumption was not. A substantial part of processed meat consumption in Israel is processed poultry, perhaps explaining the lack of association with CRC.
RESUMO
BACKGROUND: Risk for ventricular arrhythmias (VA) following cardiac resynchronization therapy (CRT) has been associated with ischemic disease/scar, sex, and possibly left ventricular mass (LVM). OBJECTIVE: To evaluate sex differences and baseline/post-implant change [Δ] of LVM on VA risk after CRT implant among patients with non-ischemic cardiomyopathy (NICM) and left bundle branch block. METHODS: Among patients meeting the criteria, baseline and follow-up echocardiographic images were obtained for LVM assessment. VA events were reported from device diagnostics and therapies. VA risk was stratified by ROC (Youden-index cut-point) for baseline LVM and ΔLVM, and baseline patient characteristics using a multivariable Cox regression model. RESULTS: 118 patients (71[60.2%] female, age 60.5 ±11.3 years, LVEF 19.2 ±7.0%, QRS 165.6 ±20 ms, LVM 313.9 ±108.8 g) were enrolled and followed for median 90 (IQR 44-158) months. Thirty-five (29.6%) patients received appropriate shocks or anti-tachycardia pacing at a median of 73.5 (IQR 25-130) months post-implant. Males had a higher VA incidence (male 18/47 [38.3%] vs. female 17/71 [23.9%], P=0.02). Baseline LVM >308.9g separated patients with higher VA risk (P=0.001). Less than a 20% decrease in LVM increased VA risk (P<0.001). Baseline LVM was the only baseline characteristic predicting VA events in the Cox regression model (Hazard ratio 1.01 [95%CI, 1.001-1.009], Log-rank P=0.003). Sex differences in VA risk were eliminated by the baseline LVM parameters. CONCLUSION: VA risk after CRT in NICM was associated with baseline LV >308.9g and a decrease in LVM ≤ 20%, without sex differences.
RESUMO
BACKGROUND AND OBJECTIVES: Incidental diffuse-weighted imaging (DWI)-positive subcortical and cortical lesions, or acute incidental cerebral microinfarcts (CMIs), are a common type of brain ischemia, which can be detected on magnetic resonance DWI for approximately 2 weeks after occurrence. Acute incidental CMI was found to be more common in patients with cancer. Whether acute incidental CMI predicts future ischemic stroke is still unknown. We aimed to examine the association between acute incidental CMI in patients with cancer and subsequent ischemic stroke or transient ischemic attack (TIA). METHODS: This is a retrospective cohort study. We used Clalit Health Services records, representing over half of the Israeli population, to identify adults with lung, breast, pancreatic, or colon cancer who underwent brain MRI between January 2014 and April 2020. We included patients who underwent scan between 1 year before cancer diagnosis and 1 year after diagnosis. Primary outcome was ischemic stroke or TIA using International Classification of Diseases, Ninth Revision codes. Secondary outcomes were intracranial hemorrhage (ICH) and mortality. Records were followed from first MRI until primary outcome, death, or end of follow-up (January 2023). Cox proportional hazards models were used to calculate hazard ratio (HR) for patients with and without acute incidental CMI, as a time-dependent covariate. RESULTS: The study cohort included 1,618 patients with cancer, among whom, 59 (3.6%) had acute incidental CMI on at least 1 brain MRI. The median (interquartile range) time from acute incidental CMI to stroke or TIA was 26 days (14-84). On multivariable analysis, patients with acute incidental CMI had a higher stroke or TIA risk (HR 2.97, 95% CI 1.08-8.18, p = 0.035) compared with their non-CMI counterparts. Acute incidental CMIs were also associated with mortality after multivariable analysis (HR 2.76, 95% CI 2.06-3.71, p < 0.001); no association with ICH was found. DISCUSSION: Acute incidental CMI on brain MRI in patients with active cancer is associated with an increased risk of near-future ischemic stroke or TIA and mortality. This finding might suggest that randomly detected acute incidental CMI in patients with cancer may guide primary cerebrovascular risk prevention and etiologic workup.

AIMS: Ventricular tachycardia (VT) non-inducibility in response to programmed ventricular stimulation (PVS) is a widely used procedural endpoint for VT ablation despite inconclusive evidence with respect to clinical outcomes in high-risk patients. The aim is to determine the utility of acute post-ablation VT inducibility as a predictor of VT recurrence, mortality, or mortality equivalent in high-risk patients. METHODS AND RESULTS: We conducted a retrospective analysis of high-risk patients (defined as PAINESD > 17) who underwent scar-related VT ablation at our institution between July 2010 and July 2022. Patients' response to PVS (post-procedure) was categorized into three groups: Group A, no clinical VT or VT with cycle length > 240 ms inducible; Group B, only non-clinical VT with cycle length > 240 ms induced; and Group C, all other outcomes (including cases where no PVS was performed). The combined primary endpoint included death, durable left ventricular assist device placement, and cardiac transplant (Cox analysis). Ventricular tachycardia recurrence was considered a secondary endpoint (competing risk analysis). Of the 1677 VT ablation cases, 123 cases met the inclusion criteria for analysis. During a 19-month median follow-up time (interquartile range 4-43 months), 82 (66.7%) patients experienced the composite primary endpoint. There was no difference between Groups A and C with respect to the primary [hazard ratio (HR) = 1.21 (0.94-1.57), P = 0.145] or secondary [HR = 1.18 (0.91-1.54), P = 0.210] outcomes. These findings persisted after multivariate adjustments. The size of Group B (n = 13) did not permit meaningful statistical analysis. CONCLUSION: The results of post-ablation PVS do not significantly correlate with long-term outcomes in high-risk (PAINESD > 17) VT ablation patients.

BACKGROUND: During pulsed field ablation (PFA), relationships between ablation parameters (contact force [CF], number of burst pulses, impedance decrease, and electrode temperature) and lesion size in beating hearts have not been well validated. METHODS: A 7.5F-catheter with a 3.5-mm ablation electrode and CF sensor (ThermoCool SmartTouch SF-Dual-Energy, Biosense Webster, Inc, Irwindale, CA) was connected to a PFA system (TRUPULSE2, Biosense Webster, Inc). In 11 closed-chest swine, biphasic PFA current was delivered between the ablation electrode and the skin patch at 219 sites in left ventricle and right ventricle using 12, 18, and 24 burst pulses with 4 different levels of CF: (1) low (n=57; CF, 4-15g; median, 10g); (2) moderate (n=60; CF, 16-30g; median, 22.5g); (3) high (n=68; CF, 32-65g; median, 40g); and (4) no electrode contact (n=34), 2 mm away from the endocardium. Swine were euthanized 2 hours after ablation, and lesion size was measured using triphenyl tetrazolium chloride staining. RESULTS: All PFA lesions with electrode-myocardium contact were well demarcated with triphenyl tetrazolium chloride staining, demonstrating (1) pale central zone (contraction band necrosis with minimal coagulation necrosis), (2) dark brown zone (contraction band necrosis with hemorrhage), and (3) hyperstained red zone by triphenyl tetrazolium chloride (unaffected normal myocardium with preserved mitochondrial activity, consistent with reversible zone). Lesion depth increased significantly with increasing CF and the number of PFA burst pulses. An exponential/logarithmic formula combined with CF and the number of PFA burst pulses correlated lesion depth with high accuracy: R=0.809, P<0.0001, ±1.0-mm accuracy in 128 of 163 (79%) lesions, and ±1.5-mm accuracy in 153 of 163 (94%) lesions. Impedance decrease and electrode temperature were poor predictors of lesion size. There were no detectable lesions resulting from ablation without electrode contact. CONCLUSIONS: Acute PFA ventricular lesions demonstrate irreversible and reversible lesion boundaries. Electrode-tissue contact is required for effective lesion formation. Lesion depth increases significantly with increasing CF and PFA burst pulses. A new exponential/logarithmic formula combined with CF and the number of PFA burst pulses correlates lesion depth with high accuracy.

INTRODUCTION: Biological and scarce epidemiological evidence suggested that phosphodiesterase-5 inhibitors (PDE5i) might reduce dementia risk. We aimed to examine the association between PDE5i and dementia using real-world data. METHODS: Two retrospective cohorts within the database of Clalit, the largest healthcare provider in Israel (2005-2023), were studied. The first cohort included new daily users, older than 50 years of age, of low-dose tadalafil, prescribed for benign prostatic hypertrophy (BPH), propensity-score matched to new-users of alpha-1 blockers, and analyzed using 2-year lag time. The second cohort included patients with erectile dysfunction, with/without any PDE5i treatment, using time-dependent analysis. Individuals in the cohorts were followed through May 2023 for the occurrence of dementia. RESULTS: The first cohort included 5,204 tadalafil initiators propensity-score matched to 18,565 alpha-1 blockers initiators. There was no association between tadalafil use and dementia risk, HR = 0.99 (95% CI: 0.88-1.12), p = 0.927. Similar results were obtained in a competing risk analysis, and in a sensitivity analysis in which we restricted the cohort to patients older than 60 years at cohort entry. The second cohort of 133,336 patients with erectile dysfunction included new users and nonusers of any PDE5i. In a mean follow-up of 7.9 years, 8,631 patients were newly diagnosed with dementia. In a time-dependent multivariable analysis, PDE5i use was not associated with reduced dementia risk, HR = 0.95 (95% CI: 0.86-1.04). Results were not changed in sensitivity analyses (patients older than 60 years or stratification by PDE5i type). CONCLUSION: This study suggests that the use of PDE5 inhibitors is not associated with decreased risk of dementia.
RESUMO
BACKGROUND: Comparative efficacy and safety data on radiofrequency ablation (RFA) versus pulsed field ablation (PFA) for common idiopathic left ventricular arrhythmia (LV-VAs) locations are lacking. OBJECTIVES: This study sough to compare RFA with PFA of common idiopathic LV-VAs locations. METHODS: Ten swine were randomized to PFA or RFA of LV interventricular septum, papillary muscle, LV summit via distal coronary sinus, and LV epicardium via subxiphoid approach. Ablations were delivered using an investigational dual-energy (RFA/PFA) contact force (CF) and local impedance-sensing catheter. After 1-week survival, animals were euthanized for lesion assessment. RESULTS: A total of 55 PFA (4 applications/site of 2.0 KV, target CF ≥10 g) and 36 RFA (CF ≥10 g, 25-50 W targeting ≥50 Ω local impedance drop, 60-second duration) were performed. LV interventricular septum: average PFA depth 7.8 mm vs RFA 7.9 mm (P = 0.78) and no adverse events. Papillary muscle: average PFA depth 8.1 mm vs RFA 4.5 mm (P < 0.01). Left ventricular summit: average PFA depth 5.6 mm vs RFA 2.7 mm (P < 0.01). Steam-pop and/or ventricular fibrillation in 4 of 12 RFA vs 0 of 12 PFA (P < 0.01), no ST-segment changes observed. Epicardium: average PFA depth 6.4 mm vs RFA 3.3 mm (P < 0.01). Transient ST-segment elevations/depressions occurred in 4 of 5 swine in the PFA arm vs 0 of 5 in the RFA arm (P < 0.01). Angiography acutely and at 7 days showed normal coronaries in all cases. CONCLUSIONS: In this swine study, compared with RFA, PFA of common idiopathic LV-VAs locations produced deeper lesions with fewer steam pops. However, PFA was associated with higher rates of transient ST-segment elevations and depressions with direct epicardium ablation.
RESUMO
Many drug labels contain precautions of use in G6PD-deficient patients due to hemolytic concerns, but much of this is based on scarce clinical, epidemiological, or structural data. In this real-world study, we aimed to examine if the administration of presumably risky medications for G6PD-deficient patients was followed by hemolysis. The study is based on data from Clalit Health Services database that provides inclusive health care for more than half of the Israeli population (~ 4.7 million). Within the database, we identified all G6PD-deficient patients by G6PD <6 U/g Hb. Within the G6PD-deficient cohort, we identified all hospitalizations with a discharge diagnosis of hemolysis (January 1, 2010 to December 31, 2022), validated the cases, and identified the culprit event. For the rest of the G6PD-deficient patients with no-hemolysis, we recorded filled prescriptions of medications listed as presumably risky. We identified 31,962 G6PD-deficient patients. Within the cohort, there were 71 cases of major hemolysis requiring hospitalization (0.2% of the cohort), of whom 51 (71.8%) had been caused by ingestion of fava beans, six (8.5%) were associated with an infection, and three (4.2%) suggested to be associated with medications (nitrofurantoin, phenazopyridine, and a "pain killer"). Within the 31,875 patients with no major hemolysis, nitrofurantoin has been prescribed safely to 1,366 G6PD-deficient males and females; hundreds/thousands of G6PD-deficient patients had been prescribed safely ciprofloxacin, glibenclamide, ofloxacin, phenazopyridine, sulfamethoxazole/cotrimoxazole, sulfasalazine, hydroxychloroquine, glimepiride, mesalazine, and sulfacetamide. In this real-world study, we are showing that a list of medications, suspected previously as carrying risks for hemolysis in G6PD-deficient patients, have been prescribed safely to G6PD-deficient patients, providing reassurance to patients, prescribers, and regulators.
RESUMO
BACKGROUND: Inclisiran, a small-interfering RNA enabling long-term inhibition of PCSK9 synthesis, demonstrates good safety and efficacy profile in clinical trials. Real-world data on the potential to attain lipid-goals and reduce treatment gaps is lacking. OBJECTIVES: To investigate the implementation of inclisiran in real-world clinical setting. METHODS: Data from a nationwide healthcare organization on patients initiating inclisiran between 3/2022-11/2023. Patients' characteristics, lipid-lowering therapies, post-treatment reduction in low-density lipoprotein cholesterol (LDL-C), and attainment of treatment goals, were evaluated. RESULTS: Inclisiran was initiated by 503 patients (57 % women; mean age 66±11 years). Cardiovascular disease was present in 54 %, and peak LDL-C levels >190 mg/dL documented in 64 %. Prior exposure to PCSK9 monoclonal antibodies was evident in 28 %. Lipid profile >2 months after filling first prescription, was available in 397 patients (347 with ≥2 injections). In patients treated by inclisiran only (n = 254), median LDL-C reduction from peak levels was 57 % (IQR, 48 %-67 %), and from pre-injection levels 40 % (19 %-54 %). In those with concomitant lipid-lowering therapies (n = 143), median LDL-C reduction from peak levels was 66 % (IQR, 55 %-73 %), and from pre-injection levels 46 % (23 %-59 %). LDL-C < 70 mg/dL was attained by 39 % and LDL-C < 55 mg/dL by 21.9 %. Of those treated with concomitant statin therapy, 38 % attained LDL-C < 55 mg/dL. Overall, 6.5 % discontinued inclisiran therapy after initial injection. CONCLUSIONS: In real-world practice, inclisiran showed good efficacy in reducing LDL-C with high interindividual variability. However, attainment rates of lipid-goals were suboptimal due to limited use of combination lipid-lowering therapy and high-rates of severe hypercholesterolemia in our patient population cohort.
RESUMO
OBJECTIVES: Recurrent Clostridioides difficile infection (CDI) poses healthcare challenges and morbidity. Preventing recurrence with prophylactic oral CDI antibiotics lack consensus. METHODS: We used data from the largest healthcare provider in Israel to identify all adults aged 18 years or older diagnosed with a first episode of CDI (Index CDI) between February 2018 and December 2022 and subsequently received a non-CDI antibiotic within 2-8 weeks. Patients who received a concurrent prophylactic CDI antibiotic constituted the CDI prophylaxis group. Multivariable Cox proportional hazard regression models were used to examine the association of secondary CDI prophylaxis with CDI recurrence according to the severity of the index CDI (primary objective) and with 4- and 8-week all-cause mortality (secondary objective). RESULTS: A total of 434 eligible patients were included. Among them, 327 did not receive CDI antibiotic prophylaxis, while 107 did. CDI antibiotic prophylaxis was associated with a significant risk reduction of CDI recurrence with an adjusted HR of 0.51 (95% CI, 0.27-0.97). The magnitude of the association was modified by the severity of the index CDI episode (P for interaction 0.0182). Specifically, the HR for recurrence was 0.163 (95% CI 0.045-0.593) for non-severe CDI, and 1.242 (95% CI 0.524-2.946) for severe CDI. No significant association was found between CDI antibiotic prophylaxis and 4-8 weeks mortality. CONCLUSION: Secondary prophylaxis with CDI antibiotics appears to be associated with a reduced risk of recurrence in patients with previous non-severe CDI episode. Further studies are needed to confirm this finding.

OBJECTIVE: COVID-19 infection and immunizations have been implicated in developing a range of thyroid diseases, including subacute thyroiditis (SAT). This study aimed to evaluate the association between COVID-19 infection and/or COVID-19 vaccination with SAT. METHODS: A population of 3 million adults insured by Clalit Health Services was evaluated from March 2020 to September 2022. Patients with a new diagnosis of SAT were identified and matched in a 1:10 ratio to a control group. Each control was assigned an index date that was identical to that of their matched case, defined as the date of SAT diagnosis. Multivariate conditional logistic regression models were used to evaluate the association between COVID-19 infection, vaccine, and thyroiditis. RESULTS: A total of 3221 patients with SAT were matched with 32 210 controls. Rates of COVID-19 vaccination (first, second, or third dose) and COVID-19 infection were evaluated prior to the date of SAT diagnosis (disease group) or index date (control group) to detect a possible association. No difference was detected between the groups in relation to vaccinations at the 30 days, 60 days, and 90 days of time points (P = .880/0.335/0.174, respectively). No difference was found between groups in relation to COVID-19 infection at these time points (P = .735/0.362/0.956, respectively). There was higher use of medications for the treatment of thyroiditis, including nonsteroidal anti-inflammatory drugs (28.6% vs 7.9%, P < .01), steroids (10.3% vs 1.8%, P < .01), and beta-blockers (18.3% vs 5.4%, P < .01). CONCLUSION: Based on this large population study, no association was found between COVID-19 infection and/or the COVID-19 vaccine and SAT.

Limited information is available on the effectiveness of COVID-19 vaccination in patients with psoriasis and psoriatic arthritis (psoriatic disease (PsD)). The objective of our research was to assess the effectiveness of mRNA COVID-19 vaccination in preventing SARS-CoV-2 positivity and severe infection in a cohort of patients with PsD and the association of immunosuppressants on SARS-CoV-2 infection-related outcomes from December 2020 to December 2021. Vaccine effectiveness was assessed in a matched nested case control study using conditional logistic regression adjusted for demographics, comorbidities and immunosuppressant use. Study outcomes included SARS-CoV-2 positivity and severe COVID-19 (moderate-to-severe COVID-19-related hospitalizations or death). At least one dose of mRNA COVID-19 vaccine was associated with reduced risk of SARS-CoV-2 positivity and severe COVID-19 (OR = 0.41 (95% CI, 0.38-0.43) and OR = 0.15 (95% CI, 0.11-0.20), respectively). A more significant effect was found among patients who received three vaccines doses compared with those who did not receive any (OR (for positive SARS-CoV-2) = 0.13 (95% CI, 0.12-0.15) and OR (for severe disease) = 0.02 (0.01-0.05)). Etanercept and methotrexate were associated with higher risk of SARS-CoV-2 positivity (1.58 (1.19-2.10), p = 0.001 and 1.25 (1.03-1.51), p = 0.03, respectively). In conclusion, our results show that mRNA COVID-19 vaccines are effective in reducing both infection and severe COVID-19-related outcomes.
RESUMO
BACKGROUND: Psoriatic arthritis (PsA) is a chronic, potentially debilitating inflammatory arthritis often associated with psoriasis. Understanding the epidemiology of PsA across diverse populations can provide valuable insights into its global burden and the role of genetic and environmental factors. This study aimed to estimate PsA's temporal trends, prevalence, and incidence, while assessing variations in age, gender, and ethnicity in Israel from 2016 to 2022. METHODS: Data were sourced from the Clalit Health Services (CHS) database, covering over half of the Israeli population. Algorithm-based definitions for PsA and psoriasis cases were used. Demographic factors, including age, gender, socioeconomic status (SES), ethnicity, urban/rural residence, BMI, and smoking status, were analyzed. Standardized prevalence and incidence rates were calculated. Logistic regression analyses examined associations of sociodemographic variables with PsA. RESULTS: In 2022, the prevalence of PsA was 0.221%, with an incidence rate of 13.54 per 100,000 population. This prevalence has tripled since 2006, reflecting a rising trend in PsA over time. Females exhibited a higher prevalence (1.15; 95%CI 1.09-1.21), and PsA was more common in Jewish individuals (1.58; 95%CI 1.45-1.71) those with higher SES (1.4; 95% CI 1.31, 1.5), and those with obesity (2.17; 95%CI 2.04-2.31). CONCLUSIONS: This comprehensive population-based study pointed to an increase prevalence of PsA, emphasizing the rising healthcare demands and economic burden faced by this patient population. Further research is essential to delve into the factors driving these trends.

BACKGROUND: Conventional focal radiofrequency catheters may be modified to enable multiple energy modalities (radiofrequency or pulsed field [PF]) with the benefit of contact force (CF) feedback, providing greater flexibility in the treatment of arrhythmias. Information on the impact of CF on lesion formation in PF ablations remains limited. METHODS: An in vivo study was performed with 8 swine using an investigational dual-energy CF focal catheter with local impedance. Experiment I: To evaluate atrial lesion formation, contiguity, and width, a point-by-point approach was used to create an intercaval line. The distance between the points was prespecified at 4±1 mm. Half of the line was created with radiofrequency energy, whereas the other half utilized PF (single 2.0 kV application with a proprietary waveform). Experiment II: To evaluate single application lesion dimensions with a proprietary waveform, discrete ventricular lesions were performed with PFA (single 2.0 kV application) with targeted levels of CF: low, 5 to 15 g; medium, 20 to 30 g; and high, 35 to 45 g. Following 1 week of survival, animals underwent endocardial/epicardial remapping, and euthanasia to enable histopathologic examination. RESULTS: Experiment I: Both energy modalities resulted in a complete intercaval line of transmural ablation. PF resulted in significantly wider lines than radiofrequency: minimum width, 14.9±2.3 versus 5.0±1.6 mm; maximum width, 21.8±3.4 versus 7.3±2.1 mm, respectively; P<0.01 for each. Histology confirmed transmural lesions with both modalities. Experiment II: With PF, lesion depth, width, and volume were larger with higher degrees of CF (depth: r=0.82, P<0.001; width: r=0.26, P=0.052; and volume: r=0.55, P<0.001), with depth increasing at a faster rate than width. The mean depths were as follows: low (n=17), 4.3±1.0 mm; medium (n=26), 6.4±1.2 mm; and high (n=14), 9.1±1.4 mm. CONCLUSIONS: Using the same focal point CF-sensing catheter, a novel PF ablation waveform with a single application resulted in transmural atrial lesions that were significantly wider than radiofrequency. Lesion depth showed a significant positive correlation with CF with depths of 6.4 mm at moderate CF.

PURPOSE: To identify potential factors associated with keratoconus. METHODS: This cross-sectional study included data from Israel's largest healthcare provider for the years 2005-2020. Keratoconus patients and age-matched controls were identified. Demographic factors and comorbid conditions, including smoking, diabetes mellitus, asthma, myalgia, mental retardation, Down syndrome, atopic dermatitis and allergy/allergic rhinitis, were compared between the two cohorts. The independent risk factors associated with keratoconus were determined using a multivariable conditional logistic regression model. RESULTS: Overall, 145 508 subjects were reviewed of which 13 228 were keratoconus patients. A ten-fold group (n = 132 280) of age-matched control subjects served as controls for comparisons. In multivariable analysis, several factors were found to be significantly associated with keratoconus. Male gender (OR = 1.27, p < 0.001), Arab ethnicity (OR = 1.50, p < 0.001), diabetes (OR = 1.19, p < 0.001), asthma (OR = 1.50, p < 0.001), myalgia (OR = 1.09, p = 0.02), mental retardation (OR = 2.63, p < 0.001), atopic dermatitis (OR = 1.35, p < 0.001) and allergic rhinitis (OR = 1.21, p < 0.001) were significantly associated with keratoconus. Smoking was significantly protective of keratoconus (OR = 0.66, p < 0.001). CONCLUSIONS: This population-based study reports male gender, Arab ethnicity, diabetes, asthma, myalgia, mental retardation/Down syndrome, atopic dermatitis and allergic rhinitis as factors associated with keratoconus while smoking demonstrates a protective effect. The results of this study could guide enhanced screening strategies and early interventions, particularly for high-risk groups.
RESUMO
BACKGROUND AND OBJECTIVES: Acute mastoiditis (AM) is a severe infection in the young population, with possible life-threatening complications. This study aimed to characterize AM presentation, symptoms and signs, complications, and management, over a period of 10 years. METHODS: This large-scale population-based cohort studied "Clalit Health Care" records, to include patients <18 years diagnosed with AM, hospitalized between the years 2008-2018. After validation, we investigated clinical symptoms and signs, pneumococcal vaccination status, complications, laboratory and microbiological parameters, imaging, antibiotic treatment and surgical interventions. RESULTS: AM was diagnosed in 1189 patients, mean age of 2.71 years and 591 (49.71%) were female. Most presented with protrusion of pinna (83.1%), retro auricular redness (73.5%) and fever (71.8%). Patients <2 years of age had more symptoms (3.8 ± 1.4, opposed to 3.6 ± 1.5, P = 0.006) and showed higher white blood cell count and C-reactive protein values. Local and intracranial complications occurred in 233 (20.8%) and 75 (6.5%) patients, respectively. Complications were associated with increased white blood cell count and C-reactive protein and related to bacterial type, specifically Fusobacterium necrophorum ( P < 0.0001), for which 50% had an intracranial complication. Between the years 2008-2018, Streptococcus pneumoniae -positive cultures decreased (30.9% to 10.3%, P > 0.0001) as opposed to group-A Streptococcus (10.9% to 30.9%, P = 0.002). CONCLUSIONS: This study shows a difference in AM appearance in the <2 years population and the association between white blood cell count, C-reactive protein and microbiology results with the occurrence of a complication. This may play a role in the management process, such as imaging and intervention needs. Although performed during the pneumococcal vaccine era, the disease microbiology was shown to change significantly throughout the study.
