    Abstract: This study aimed to compare the clinical features, damage accrual, and survival of patients with familial and sporadic systemic lupus erythematosus (SLE). Methods A multi-ethnic, multinational Latin American SLE cohort was studied. Familial lupus was defined as patients with a first-degree SLE relative; these relatives were interviewed in person or by telephone. Clinical variables, disease activity, damage, and mortality were compared. Odds ratios (OR) and 95% confidence intervals (CI) were estimated. Hazard ratios (HR) were calculated using Cox proportional hazard adjusted for potential confounders for time to damage and mortality. Results A total of 66 (5.6%) patients had familial lupus, and 1110 (94.4%) had sporadic lupus. Both groups were predominantly female, of comparable age, and of similar ethnic distribution. Discoid lupus (OR = 1.97; 95% CI 1.08–3.60) and neurologic disorder (OR = 1.65; 95% CI 1.00–2.73) were significantly associated with familial SLE; pericarditis was negatively associated (OR = 0.35; 95% CI 0.14–0.87). The SLE Disease Activity Index and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) were similar in both groups, although the neuropsychiatric (45.4% vs. 33.5%; p = 0.04) and musculoskeletal (6.1% vs. 1.9%; p = 0.02) domains of the SDI were more frequent in familial lupus. They were not retained in the Cox models (by domains). Familial lupus was not significantly associated with damage accrual (HR = 0.69; 95% CI 0.30–1.55) or mortality (HR = 1.23; 95% CI 0.26–4.81). Conclusion Familial SLE is not characterized by a more severe form of disease than sporadic lupus. We also observed that familial SLE has a higher frequency of discoid lupus and neurologic manifestations and a lower frequency of pericarditis.

    Abstract: At the time of our study, occupational health evidence specific for long-term care employees was mostly lacking. The purpose of this study was to determine the proportion of positive cases in employees after the first COVID-19 wave in May 2020. We also determined the prevalence of asymptomatic cases. Method: The study population included all health care workers (HCW) employed at one mid-size long-term hospital in Spain (May 2020). A cross-sectional study design included an interviewer-administered self-reported questionnaire (including sociodemographic questions, risk factors for COVID-19 complications such as hypertension or diabetes, and previous polymerase chain reaction [PCR] results) and antibody determination (Biozek rapid test). Data were analyzed using Student’s t, Fisher, and chi-square tests. Two multivariate logistic models were created to evaluate exposure factors and symptoms separately on the outcome of having had COVID-19. Findings: Of the 97% of workers who participated (580/596), 300 (51.7%) suffered symptoms of COVID-19, 161 (27.8%) of the rapid antibody tests were positive for IgM and/or IgG, 160 (27.6%) workers had at least one risk factor, and 32 (19.0%) of the 168 SARS-CoV-2-positive cases were asymptomatic. The proportion of negative or unavailable PCRs, with positive antibody, was 11.7% (56/477). Casual contact without protection (odds ratio [OR]: 1.9, 95% confidence interval [CI] : 1.1–3.4), doctor occupation (OR 3.3, 95% CI: 1.1–10.2), and nursing assistant occupation (OR 2.5, 95% CI: 1.2–5.8) were independently associated with SARS-CoV-2 infection. Conclusion: Physicians and nursing assistants in a long-term care setting were at a higher risk of SARS-COV-2 infection over other occupations in the first wave of the pandemic, especially when in contact with patients without protection. Almost one-fifth of the workers with a positive PCR test for SARS-COV-2 were asymptomatic and seroprevalence (27.8%) was well below the approximated herd immunity cutoff (60–70%). Essential workers in long-term care must be monitored frequently by Employee Health Service and should be required to wear personal protective equipment including a fit-tested N-95 while in close contact with patients and coworkers.

    In: European Journal of Ophthalmology, SAGE Publications
    Abstract: To compare cross-linking (CXL) plus topography-guided photorefractive keratectomy (t-PRK) and intrastromal corneal ring segments (ICRS) in keratoconus patients, at 12 months of follow-up. Methods This was a longitudinal, retrospective multi-center study. We included a referred sample of 154 eyes from 149 patients with grade I-III Amsler-Krümeich keratoconus with insufficient corrected-distance visual acuity (CDVA). In group 1 (CXL plus t-PRK, 87 eyes), another possible indication for surgery was evidence of progression. Group 2 (ICRS, 67 eyes) included only eyes with paracentral keratoconus (thinnest point at the inferotemporal quadrant) with coincident axes, and evidence of stabilization was required. A subgroup analysis was performed regarding the disease topographic phenotype. At 12 months postoperatively, visual, refractive, and topographic outcomes were evaluated. Results Comparison of the outcomes between CXL plus t-PRK (group 1) and ICRS (group 2) showed similar improvements in CDVA (in group 1, CDVA improved 0.18 logMAR, and in group 2 0.12 logMAR, P = .18) and K2 (−2,45 [6.46] D in group 1 and −2.13 [1.67] D in group 2, P = .34) The improvement in cylinder power was greater in group 2 (−2.37 [2.07] D in group 2 versus −1.18 [2.63] D in group 1, P = .003); group 1 had a higher decrease in Kmax (- 3.26 [3.64] versus—1.74 [2.67] , P = .001). Conclusions Both CXL plus t-PRK and ICRS were equally effective in improving CDVA and topographic parameters in a similar group of keratoconus patients at 12 months.

    The influence of personality on the quality of vision after multifocal intraocular lens implantation
    SAGE Publications ; 2023
    In:  European Journal of Ophthalmology
    Details
    In: European Journal of Ophthalmology, SAGE Publications
    Abstract: To assess the possible correlation between patients’ personality traits and subjective perception of quality of vision (QoV), after multifocal intraocular lens (mIOL) implantation. Methods patients who had bilateral implantation of a non-diffractive X-WAVE or a trifocal lens were assessed 6 months postoperatively. Patients answered the NEO-Five Factor Inventory (NEO-FFI-20) questionnaire (“Big Five five-factor personality model”) to examine their personality. Six months following surgery, patients were asked to fill a QoV questionnaire where they graded the frequency of 10 common visual symptoms. Primary outcomes were to evaluate the correlation between personality scores and the reported frequency of visual disturbances. Results The study comprised 20 patients submitted to bilateral cataract surgery, 10 with a non-diffractive X-WAVE lens (AcrySof® IQ Vivity) and 10 with a trifocal lens (AcrySof® IQ PanOptix). Mean age was 60.23 (7.06) years. Six months following surgery, patients with lower scores of conscientiousness and extroversion reported a higher frequency of visual disturbances (blurred vision, P  =  .015 and P  =  .009, seeing double images P  =  .018 and P  =  .006, and having difficulties focusing, P  =  .027 and P  =  .022, respectively). In addition, patients with high neuroticism scores had more difficulty focusing ( P  =  .033). Conclusions In this study, personality traits such as low conscientiousness and extroversion and high neuroticism significantly influenced QoV perception 6 months after bilateral multifocal lens implantation. Patients’ personality questionnaires could be a useful preoperative assessment test to a mIOL.

    Abstract: High-pressure sodium lamps are currently the main lamps used in public lighting. However, the possibility of using high-power light emitting diode (LEDs) for street lighting is growing continuously due to their greater energy efficiency, robustness, long life and light control. The aim of this paper is to study the power quality of high-power lighting networks based on LED and high-pressure sodium lamps. Both electromagnetic and dimmable electronic ballasts, which can dim the lamp output smoothly and uniformly, have been used connected to high-pressure sodium lamps. High-pressure sodium lamps connected to electronic equipment have been tested with different arc power levels using dimming on a 230 V power supply. The study presented in this paper is completely based on measurements, including harmonic currents in the frequency range up to 150 kHz for all the technologies. The main results show a broadband spectrum in LED lamps which confirms other research in fluorescent lamps powered by high-frequency ballasts. Results also indicate a decrease in the harmonic value with increasing harmonic order, and a decrease in the harmonic value at half load (60%) compared with full load (100%). Although total harmonic distortion of the current is lower with high-pressure sodium lamps connected to electronic rather than electromagnetic ballasts, LED lamps achieved the lowest total harmonic distortion of current.

    Abstract: The aim of the study was to evaluate the relationship between sedentary behavior, bone mass, and bone geometry among young male basketball and volleyball players. This cross-sectional study included 55 adolescent basketball ( n = 21) and volleyball ( n = 34) players (14–17 years). Body composition (body mass index, fat mass, and lean mass) was measured by dual-energy X-ray absorptiometry, comprising bone mineral density, bone mineral content at the lumbar spine, and femoral neck. Bone geometry considered the femur strength index, section modulus, cross-sectional moment of inertia, and cross-sectional area. Dietary intake was obtained through a semiquantitative questionnaire, and the sedentary behavior, by the Adolescent Sedentary Activity Questionnaire. Linear regression models, fitted by Bayesian methods, explored the variation of the variables by sport. Body composition and bone mass values were high for both sports, but there was no variation for body composition. Adjusting for age, there was no association of sedentary behavior on bone parameters. For femoral strength index, age had a moderate to large association with all bone indicators. Lastly, there was influence of sport (level-2 unit) on the estimates of the association between sedentary behavior and age with bone indicators, as uncertainty estimates for group-level effects were high. There is no association between sedentary behavior and bone parameters, showing that accumulated training loads (15+ h/wk) among young basketball and volleyball players are critical; producing a positive stimulus on bone parameters development.

    Abstract: Life is Precious (LIP) was developed to help reduce suicidal behavior in Latina adolescents. As part of an external evaluation of the LIP program, we conducted focus groups with adolescent participants and mothers to learn whether participants and families believe that the activities of LIP address risks for suicidal behavior. Four focus groups were conducted: three with Latina adolescent LIP participants ( n = 31) and one with mothers ( n = 8). Transcripts were analyzed using ATLAS.ti. A grounded theory approach was used to identify themes and subthemes. The following themes emerged: (1) challenges contributing to suicidal behavior and self-harm among Latina adolescents, (2) how respondents believe that LIP is helping to reduce suicidal behavior, and 3) ongoing challenges. Participants say that the LIP program helps adolescents feel better and improve social relationships, academic performance, and relationships with their family. School nurses may wish to identify community-based programs offering similar services.

    Abstract: Less advantaged social classes usually have unhealthier lifestyles and have more difficult access to health resources. In this work we study the possible association between poverty and the prevalence of obesity and oophorectomy in a population of postmenopausal women. Design Cross-sectional observational study. Objective To study in a population of postmenopausal women in poverty the possible differences in the prevalence of obesity and oophorectomy, and to compare some other gynaecological data: age at menarche, age at menopause, fertile years, number of pregnancies, breastfeeding and the use of hormonal replacement therapy (HRT). Method All patients were interviewed personally. A questionnaire was used to find out about their lifestyles and the medication they were taking. Their medical records were reviewed to confirm the existence of some diseases. A complete physical examination was performed with every patient. Weight and height were measured with the patient dressed in light clothes. Blood was obtained in a fasting state in order to carry out some analyses. Poverty was defined according to the Spanish National Institute of Statistics criteria. Results We enrolled 1225 postmenopausal women; 449 (36.6%) were under the threshold of poverty, defined by the Spanish National Institute of Statistics. Postmenopausal women in poverty had higher body mass index (29.2 ± 4.8 versus 27.0 ± 4.7 kg/m 2 P 〈 0.001), and a higher prevalence of obesity than postmenopausal women not in poverty (44.2% versus 24.3%, P = 0.001). The prevalence of oophorectomy was also higher in women in poverty (32.7% versus 27.2%, P 〈 0.04). Women in poverty had had a greater number of pregnancies (3 versus 2, P = 0.001). They also showed a higher rate of breastfeeding than women in medium and high social classes (65% versus 59%, P = 0.037). There were no statistically significant differences between the groups in either the age of menopause or fertile years, nor in the use of HRT. Conclusions Postmenopausal women in poverty have higher levels of obesity, and also a greater prevalence of oophorectomy than women of medium and high social classes. They also presented a higher rate of breastfeeding and a greater number of pregnancies than those women not in poverty.

    Abstract: Enteric peritonitis (EP) is an infrequent complication of peritoneal dialysis (PD), with severe consequences for peritoneal membrane viability and patient outcome. Factors such as diverticular disease and gastric acid inhibitors have been implicated in its appearance. We investigated several risk factors, including those mentioned below, that can influence the development of EP. Design Retrospective cross-sectional study. Setting Tertiary-care public university hospital. Patients Fifty-seven PD patients treated in our PD unit during August 1998. Main Outcome Measures A barium enema was performed on 50 of the 57 patients (the remaining 7 patients refused it) in order to exclude the presence of diverticulosis. All episodes of peritonitis occurring in those patients, including EP, were registered. Enteric peritonitis was defined as that caused by gram-positive, gram-negative, or fungus micro-organisms that colonized the intestinal tract, excluding episodes secondary to genitourinary tract or peritoneal catheter exit-site infections. Results Twenty-four patients showed diverticular disease in the barium enema, but only 5 of them (21%) had any EP episode. Five of the 26 patients with no diverticula (19%) had EP. Fifty-five episodes of peritonitis were reported in 21 patients; 15 episodes of EP (27.3% of all) developed in 11 patients. Seven of the 11 patients (64%) required peritoneal catheter removal and 3 of them (27%) finally were transferred to hemodialysis due to consequences of the EP episode. Logistic regression analysis did not find any of the independent variables analyzed (age, sex, time on PD, type of PD, peritoneal transport parameters, presence of polycystic kidney disease, constipation or diverticulosis, or treatment with gastric acid inhibitors, or phosphate-binding agents) to be risk factors for developing EP. Conclusions Neither diverticulosis nor treatment with gastric acid inhibitors seem to be risk factors for developing peritonitis of enteric origin in PD patients. This type of peritonitis has to be promptly identified and treated in order to diminish the high frequency of peritoneal catheter removal and PD dropout due to such episodes.

    Abstract: Nest placement affects the risk of predation and determines the microclimate for incubation. We have analysed the nest placement of the blackbird nests and the temperatures at which they are exposed in an orange plantation from Eastern Spain. The data come from a 16.9 ha of an orange plantation. In this plot, nest searching techniques were applied. Nest placement and the temperatures at midday were recorded from a sample of 84 nests. Furthermore, a sample of 16 nests was used to determine the daily variation between 8:00 and 20:00 hours. We measured the nest height, tree height, and distance from the tree centre to the nest, and the length of the longest branch. The temperatures inside the nest cup and of the surrounding air temperatures were also obtained. The range of the orange tree height was 82-425 cm (mean = 234.0 cm). The length range of the longest branch was 11-311 cm (mean = 136.4). The nests were placed at heights between 41 and 223 cm (mean = 134.4) and the distance from the centre of the tree varied from 8 to 233 (mean = 126.5). There was no variation in the nest heights and distances from the trunk to the nest place as the breeding season progresses. The air temperature (T at ) and the nest temperature (T ict ) at midday increases as the breeding season progresses but the difference between T at and T ict did not vary according to the time in the breeding season. The daily difference between the air and the nest temperatures increased from 08:00h to 12:00h and then decreased. Only three nests out of the 100 nests sampled were successful inbreeding.
