ABSTRACT

BACKGROUND: Some preliminary studies indicate that components in coffee may have anticarcinogenic effects. However, the association between coffee-drinking habits and the risk of NHL remain controversial.

OBJECTIVE: To examine the relationship between coffee intake and non-Hodgkin’s lymphoma (NHL) incidence in a large prospective study of postmenopausal US women.

DESIGN AND PARTICIPANTS/SETTING: The participants included 74,935 women from the Women’s Health Initiative Observational Study (WHI-OS) who were recruited from 1993 through 1998. Information about coffee-drinking habits was collected at baseline via self-administered questionnaires.

MAIN OUTCOME MEASURES: Newly diagnosed NHL was validated by medical records and pathology records. Separate analyses were performed for the following three subtypes of NHL: diffuse large B-cell lymphoma (DLBCL (n=244)), follicular lymphoma (FL (n=166)), and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL (n=64)).

STATISTICAL ANALYSES PERFORMED: Age-adjusted and multivariable-adjusted Cox proportional hazards models were used to determine associations of coffee intake (specifically, the total amount of coffee consumed daily, coffee types, and coffee preparation methods) with risk of NHL.

RESULTS: A total of 851 women developed NHL during a median 18.34 years of follow-up (range, 0.01 to 24.30 years; SD ± 6.63 years). Overall, no associations were observed between coffee intake and risk of NHL regardless of the total amount of daily coffee intake (P-value for trend test = 0.90), caffeinated (P-value=0.55) or decaffeinated coffee intake (P-value=0.78), and filtered or unfiltered coffee intake (P-value=0.91) after controlling for sociodemographic factors, lifestyle risk factors, and clinical risk factors/current medical conditions. No significant associations were observed between coffee intake with specific subtypes of NHL. A statistically significant interaction was found between alcohol intake, coffee intake, and incident NHL (P-value for interaction=0.02) based on the adjusted analysis. Specifically, among women who frequently consumed alcohol (>7 drinks/week), those who had moderate coffee intake (2-3 cups coffee/day) had a significantly reduced risk of developing NHL (HR:0.61, 95%CI: 0.36-0.98), compared to those who did not drink coffee.

CONCLUSION: The findings from this study do not support an association between coffee consumption and NHL risk, irrespective of the total amount of daily coffee intake, coffee types, or coffee preparation methods.

ABSTRACT

PURPOSE: To compare the optical coherence tomography angiography (OCT-A) of the macula, and optic disc in primary open-angle glaucoma (POAG), pseudoexfoliation glaucoma (PXG), and normal eyes.

METHODS: In this observational, cross-sectional study, Sixty-five eyes with POAG, 61 eyes of age, and mean deviation (MD) from standard automated perimetry matched PXG patients, and 45 normal control eyes underwent OCT-A using AngioVue, and optic disc-associated vessel density (VD), macular-associated VD, Foveal avascular zone (FAZ) area, FAZ perimeter (PERIM), and vessel density within a 300 μm wide region of the FAZ (FD) were compared between groups.

RESULTS: Peripapillary OCT-A parameters were significantly different among normal, and glaucomatous eyes with the highest values in the control eyes, but none of the peripapillary OCT-A parameters except inside disc VD was statistically significantly different between the PXG eyes, and POAG eyes. Correlation analysis revealed significant correlation between mean retinal nerve fiber layer (RNFL) and peripapillary VD in control (r=0.427, P=0.006), PXG (r=0.82, P<0.001), and POAG (r=0.79, P<0.001) eyes. PXG eyes exhibited significantly lower superficial, and deep macular vessel densities in parafoveal and perifoveal regions compared with POAG eyes after adjustment (p<= 0.05). Overall, moderate /severe PXG eyes had lower superficial, and deep vessel densities in parafoveal and perifoveal regions compared to mild PXG.

CONCLUSION: Peripapillary VD (inside disc), and macular vessel densities (parafovea and perifovea) demonstrate a significant difference in age and glaucoma severity-matched POAG and PXG eyes. Moderate/advance glaucomatous eyes, exhibit significant damage to the superficial and deep macular vascular structures.

ABSTRACT

BACKGROUND: The prevalence of sesame allergy is increasing; strict avoidance is the mainstay of therapy. Lately, sesame oral immunotherapy was presented as an alternative treatment, with a high rate of success. Therefore, data about the natural history and the clinical characteristics of patients with persistent sesame allergy are important for the management of sesame allergic patients.

OBJECTIVE: To describe the natural history of sesame allergic patients and the clinical characteristics of patients with spontaneous resolution of sesame allergy compared to patients with persistent sesame allergy.

METHODS: In our retrospective study, electronic health records of patients with sesame allergy diagnosis were reviewed for demographic and clinical data. Statistical analysis of clinical characteristics of patients with spontaneous resolution compared to persistent sesame allergy was performed.

RESULTS: One hundred and ninety patients with sesame allergy were followed for 3.86±4.43 years. Sixty one (32.1%) of them had spontaneous resolution of sesame allergy. Patients with mild, early (before the age of 10 months) first sesame allergic reaction, with smaller than 7 mm skin prick test and without concomitant tree nuts allergy had better resolution rate (56.1%).

CONCLUSION: Sesame allergy spontaneously resolved in about one third of our patients and in more than half of the patients with mild first reaction (grade 1) at a young age (<10 months), with small skin prick test (<7mm) and no concomitant tree nuts allergy. Larger prospective studies, with longer follow up period are needed to better characterize the sesame allergic patients with persistent allergy, who may need oral immunotherapy.

ABSTRACT

AIM: To evaluate the shear bond strength (SBS) of caries affected dentin (CAD) bonded to resin-modified glass ionomer cement (RMGIC) after being disinfected with different methods of disinfection and their effect on microleakage scores.

MATERIAL AND METHODS: Based on criteria of ICDAS seventy-five teeth were selected and disinfected. All samples were grounded and a cavity prepared followed by random allocation of samples into different disinfection groups i.e., methylene blue photosensitizer (MBP), Silver diamine fluoride (SDF), Ozone (O₃); curcumin photosensitizer (CP) and chlorhexidine (CHX) (n=15). All samples were restored with resin modified glass ionomer (RMGIC) incrementally. Ten specimens from each group were placed in universal testing machine (UTM) to calculate bond failure and failure type. Five samples from each group were evaluated for microleakage scores. SBS and microleakage scores was examined using analysis of variance (ANOVA) with a Post-hoc test. For all tests p-value, less than 0.5 was considered statistically significant.

RESULTS: The highest SBS was observed in CAD disinfected with CP bonded to RMGIC (16.42 ±1.10 MPa). Similarly, the lowest bond values were demonstrated by CAD disinfected with MBP (9.21 ± 0.22 MPa) bonded to RMGIC respectively. CAD disinfected with CHX (Control) bonded to RMGIC demonstrated the lowest microleakage scores and showed a significant difference compared to other experimental groups (p< 0.05).

CONCLUSION: Curcumin along with O₃ has the potential to be used as a disinfectant in CAD as it improves SBS to RMGIC. CHX demonstrates low microleakage scores with decrease bond integrity.

ABSTRACT

This cross-sectional study estimated associations of eating contexts (including regularity of meals, places where they occur, and if they take place with attention and in company) with food consumption by degree of industrial processing and overweight indicators in a sample of Brazilian adolescents (14-19 years old) enrolled in 29 public schools in Juiz de Fora, MG (n = 805). We used an exploratory questionnaire, which was submitted to cluster analysis. Three clusters were identified: cluster 1 (n = 572), “appropriate eating contexts at breakfast, lunch, and dinner”; cluster 2 (n = 139), “inappropriate eating context at breakfast”; and cluster 3 (n = 94) “inappropriate eating context at dinner”. The evaluation of food consumption involved two 24-h dietary recalls, whose items were analyzed according to the NOVA classification system. Linear regression models were performed, using cluster 1 as reference. Clusters 2 and 3 were associated with an increase in the energy fraction from ultra-processed foods [respectively, β = 2.55% (IC 95%: 0.50; 5.05) and β = 4.18% (IC 95%: 1.21; 7.14)]; and cluster 2 was associated with a reduction in the energy fraction from unprocessed or minimally processed foods and culinary preparations [β = -3.61% (IC 95%: -6.40; -0.82)]. Additionally, clusters 2 and 3 were associated with an increase of body mass index for age [respectively, β = 0.23 z-score (IC 95%: 0.01; 0.46) and β = 0.27 z-score (IC 95%: 0.02; 0.54)]; and cluster 2 was associated with an increase of body fat [β = 1.21% (IC 95%: 0.23; 2.64)]. In conclusion, inappropriate eating contexts at breakfast and dinner were associated with higher ultra-processed food intake, higher body mass index and higher body fat percentage.

ABSTRACT

Registries are essential for health infrastructure planning, benchmarking, continuous quality improvement, hypothesis generation and real world trials. To date, data from these registries have predominantly been analysed in isolated “silos”, hampering efforts to analyse “big data” at the international level, with wide-ranging benefits including enhanced statistical power, an ability to conduct international comparisons, and greater capacity to study rare diseases. This review serves as a valuable resource to clinicians, researchers, and policymakers by comprehensively describing kidney failure registries active in 2021, before proposing approaches for inter-registry research under current conditions and solutions to enhance global capacity for data collaboration. We identified 79 kidney failure registries spanning 77 countries worldwide. International Society of Nephrology exemplar initiatives, including the “Global Kidney Health Atlas” and “Sharing Expertise to support the set-up of Renal Registries (SharE-RR)” continue to raise awareness regarding international healthcare disparities and support the development of universal kidney disease registries. Current barriers to inter-registry collaboration include under-representation of lower income countries, poor syntactic and semantic interoperability, absence of clear consensus guidelines for healthcare data sharing, and limited researcher incentives. This review represents a call to action for international stakeholders to enact systemic change that will harmonise the current fragmented approaches to kidney failure registry data collection and research.

ABSTRACT

BACKGROUND: Cardiac sarcoidosis (CS) is clinically diagnosed in 5% of patients with sarcoidosis but imaging studies suggest higher prevalence. We evaluated the prevalence, clinical manifestations, and cardiovascular outcomes of CS, diagnosed through ¹⁸F-Fluorodeoxyglucose positron emission tomography ([¹⁸F]FDG-PET), in a southern European population.

METHODS: Retrospective single-centre study of patients screened for sarcoidosis with [¹⁸F]FDG-PET. Subjects with histological confirmation were divided in two groups, CS or extracardiac sarcoidosis, according to Heart Rhythm Society’s criteria. Primary endpoint was defined as the composite of heart failure hospitalizations, uncontrolled arrythmias, pacemaker implantation, and cardiovascular (CV) mortality. Secondary outcomes included each component and all-cause mortality.

RESULTS: From 128 patients with biopsy-proven extracardiac sarcoidosis, 10.2% had probable CS, 54% without symptoms of cardiac involvement. Ten patients had suggestive [¹⁸F]FDG uptake patterns, three subjects had an indicative cardiac magnetic resonance (CMR). Patients with probable CS had significantly higher prevalence of coronary and valvular disease, heart failure, and atrial fibrillation compared with those without cardiac involvement. During a mean follow-up of 4.0 SD2.7 years, the primary outcome occurred more frequently in patients with probable CS (53.8% vs. 3.5%; HR 25.45; 95% CI 5.27-122.9; p < 0.01) as well as heart failure hospitalizations (46.2% vs. 0.9%), uncontrolled arrhythmias (23.1% vs. 1.7%) and pacemaker implantation (23.1% vs. 0.9%) (p < 0.01 for all). All-cause mortality was three-fold higher in probable CS, despite the absence of statistical significance (15% vs. 5%, p = 0.15).

CONCLUSIONS: Among patients with biopsy-proven sarcoidosis, cardiac involvement detected by [¹⁸F]FDG-PET or CMR is associated with a higher risk of CV events, irrespective of symptoms.

ABSTRACT

BACKGROUND AND AIMS: With the increasing incidence of small gastrointestinal stromal tumors (GISTs), endoscopic full-thickness resection (EFR) and cap-assisted EFR (EFR-C) have been suggested as 2 effective resection methods. We aimed to compare the outcomes of EFR and EFR-C for the treatment of small (≤ 1.5 cm) gastric GISTs.

METHODS: This retrospective study included 67 patients who underwent EFR and 46 patients who underwent EFR-C at Nanjing Drum Tower Hospital. Clinicopathological features, adverse events and outcomes were compared between the 2 groups. Univariate and multivariate linear and logistic regressions were used to analyze the effects of the procedure on the therapeutic outcomes of patients and adjusted for covariates in multivariate analysis.

RESULTS: The tumor size in the EFR group tended to be larger (P = 0.005). The resection time in the EFR-C group was shorter than that in the EFR group (38.3 ± 20.7 min vs 15.0 ± 11.8 min, P < 0.001), which retained statistical significance with adjustment for the covariates (adjusted mean difference: 22.2; 95% CI, 15.0-29.4, P < 0.001). The R0 resection rate of the EFR group was 94.0%, and for the EFR-C group, it was 97.8% (P = 0.355). The EFR-C group was superior to the EFR group in terms of perioperative therapeutic outcomes, adverse events and postoperative recovery. No recurrence occurred in the EFR and EFR-C groups.

CONCLUSION: EFR-C was found to be the preferable technique for small (≤1.5 cm) gastric GISTs with shorter operation times, lower adverse events, faster postoperative recovery, and shorter hospitalization times as compared with those with EFR.

ABSTRACT

This response aims to expand on some of the issues raised by Keith Baverstock’s The Gene: An Appraisal, especially on the evolution and nature of knowledge in living things. In contrast to the simple associationism envisaged in “genetic information”, it emphasises the dynamic complexity and changeability of most natural environments, and, therefore, predictability based on underlying statistical structures. That seems to be the basis of the “cognitive” functions increasingly being reported about cellular, as well as more evolved, functions, and of the autonomous agency of organisms thriving creatively in complex environments.

ABSTRACT

BACKGROUND: The Maastricht University Medical Center+ (MUMC+) is a Dutch center of expertise, appointed by the Netherlands Federation of University Medical Centres (NFU), for the treatment of thymomas. The aim of this study was to investigate the long-term oncological-, surgical-, and neurological outcomes of all patients who underwent a robotic thymectomy for a thymoma at the MUMC+.

METHODS: We retrospectively analyzed the clinical-pathological data of all consecutive patients with a thymoma who underwent robotic thymectomy using the DaVinci® Robotic System at the MUMC+ between April 2004 and December 2018. Follow-up data were collected from 60 referring Dutch hospitals.

RESULTS: In total, 398 robotic thymectomies were performed and 130 thymomas (32.7%) were found. Median follow-up time, procedure time and hospitalization were 46 months, 116 minutes and 3 days, respectively. In 8.4% of the patients a conversion was performed and in 20.8% a complication was registered. The majority of myasthenic patients with a thymoma went into remission, mostly within 12 to 24 months after thymectomy (81.0%). No statistical difference was found in the number of complications, conversions, incomplete resections or deaths between patients with myasthenia gravis and nonmyasthenic patients. Thirty-six patients (27.7%) underwent postoperative radiotherapy. The recurrence rate was 9.1% and the five-year thymoma-related survival rate was 96.6% .

CONCLUSIONS: Robotic thymectomy was found to be safe and feasible in early-stage thymomas, most advanced-stage thymomas and thymomatous myasthenia gravis. A national guideline could contribute to the improvement of the oncological follow-up of thymic epithelial tumors in the Netherlands.
