RESUMO

OBJECTIVE: Multiple strategies have been utilised to reduce the incidence of HIV, including PrEP and rapid antiretroviral therapy initiation. The study objectives were to evaluate the efficacy, safety, satisfaction, treatment adherence, and system retention obtained with rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in naïve patients. METHODS: This phase IV, multicenter, open-label, single-arm, 48-week clinical trial enrolled patients between January 2020 and June 2022. Adherence to treatment was evaluated with the SMAQ questionnaire and patient satisfaction with the EQ-5D. RESULTS: Two hundred eight participants were enrolled with mean age of 35.6 years; 87.6% were males; mean CD4 count was 393.5 cells/uL (<200 cells/uL in 22.1%); viral load log was 5.6 (VL>100 000 cop/mL in 43.3%); 22.6% had AIDS, and 4.3% were coinfected with HBV. BIC/FTC/TAF was initiated on the day of their first visit to the HIV specialist in 98.6% of participants, and 9.6% were lost to follow-up. The efficacy at week 48 was 84.1 % by intention-to- treat (ITT), 94.6% by modified ITT, and 98.3% by per protocol analysis. The regimen was discontinued in two subjects (0.9%) during week 1 for grade 3 adverse events. Treatment adherence (weeks 4 [90%, IQR: 80-99%] vs. 48 [90%, IQR: 80-95%; P = 0.49]) and patient satisfaction (weeks 4 [90%, IQR: 80-99%] vs. 48 [90%, IQR: 80-95 P = 0.49]) rates were very high over the 48- week study period. CONCLUSIONS: BIC/FTC/TAF is an appropriate option for rapid ART initiation in naïve HIV patients, offering high efficacy, safety, durability, treatment adherence, retention in the healthcare system, and patient satisfaction. Number Clinical Trial registration: NCT06177574.

RESUMO

To date, former research about the impact of HIV infection on mpox poor outcomes is still limited and controversial. Therefore, the aim of this study was to assess the impact of HIV on the clinical course of mpox, in a large population of patients from Spain. Nationwide case-series study. Patients from 18 Spanish hospitals, with PCR-confirmed mpox from April 27, 2022 to June 30, 2023 were included in this study. The main outcome was the development of long or complicated (LC) mpox, defined as: (i) duration of the clinical course ≥ 28 days, or; (ii) disseminated disease, or: (iii) emergence of severe complications. One thousand eight hundred twenty-three individuals were included. Seven hundred eighty-six (43%) were people living with HIV (PLWH), of whom 11 (1%) had a CD4 cell count < 200 cells/mm3 and 33 (3%) <350 cells/mm3 . HIV viral load ≥ 1000 cp/mL was found in 27 (3%) PLWH, none of them were on effective ART. Fifteen (60%) PLWH with HIV-RNA ≥ 1000 cp/mL showed LC versus 182 (29%) PLWH with plasma HIV-RNA load < 1000 copies/mL and 192 (24%) individuals without HIV infection (p < 0.001). In multivariate analysis, adjusted by age, sex, CD4 cell counts and HIV viral load at the time of mpox, only plasma HIV-RNA ≥ 1000 cp/mL was associated with a greater risk of developing LC mpox [adjusted OR = 4.06 (95% confidence interval 1.57-10.51), p = 0.004]. PLWH with uncontrolled HIV infection, due to lack of ART, are at a greater risk of developing LC mpox. Efforts should be made to ensure HIV testing is carried out in patients with mpox and to start ART without delay in those tested positive.

RESUMO

Background: Vitamin D receptor (VDR) is a nuclear hormone receptor widely expressed in the substantia nigra. Its association with an increased risk of Parkinson's disease (PD) is based on vitamin D deficiency and/or different polymorphisms in its gene receptor. This fact has been demonstrated by several case-control studies. Materials and Methods: Consequently, we investigated the association between VDR ApaI, BsmI, FokI, and TaqI gene polymorphisms and PD in a Spanish cohort that included 54 cases and 17 healthy controls. The detection of single nucleotide polymorphisms (SNPs) was performed using a polymerase chain reaction-restriction fragment length polymorphism. Results: Our data indicate that the SNPs were not associated with the age of onset of PD, nor with the occurrence of motor symptoms. However, only BsmI polymorphism was significantly associated with PD in this Spanish cohort. In fact, BsmI genotype was five times higher among PD patients than among controls, and the A allele was considered as a genetic risk for PD. Additionally, the combination of FokI and BsmI polymorphisms was significantly associated with PD and could represent a risk factor. Conclusion: We conclude that ApaI, TaqI, and FokI polymorphisms were not associated with PD, but BsmI could be a risk factor for PD in this randomized population.

RESUMO

BACKGROUND: Switching strategy with bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) has become a gold standard for people living with HIV (PLWH), achieving high efficacy and safety rates. However, data regarding immune status in long-term real-life cohorts of pretreated patients are needed. METHODS: We performed a multicentre, non-controlled, retrospective study in virologically suppressed PLWH switching to B/F/TAF. We evaluated CD4+, CD8+ and CD4+/CD8+ ratio, efficacy and safety at weeks 48 and 96. RESULTS: The study comprised 1966 PLWH from 12 hospitals in Spain, of whom 80% were men, and the median age was 51.0 [42.0-57.0] years. The median time of HIV infection was 18.0 [10.0-27.0] years. No significant changes in CD4+, CD8+ T cells, or CD4+/CD8+ were observed after 96 weeks. Nevertheless, in women at weeks 48 and 96, we found a significant increase of CD4+ T cells and a significant decrease in CD8+ T cells. In patients ≥60 years at week 96, CD4 T cells significantly increased and CD8+ T cells significantly decreased at week 48. The on-treatment analysis revealed HIV-RNA <50 copies/mL in 95.6% (1700/1779) and 96.7% (1312/1356) of patients at weeks 48 and 96, respectively. The rates increased to 99.2% (1765/1779) and 99.7% (1352/1356) when considering HIV-RNA <200 copies/mL. No resistance mutations were detected in virologic failures. B/F/TAF discontinuations accounted for 10.2% (200). Simplification was the most common reason for discontinuation in 3.8% (74) of patients. CONCLUSION: In long-term virologically controlled PLWH, B/F/TAF achieved high efficacy rates and slightly improved immune status in women and individuals aged 60 and over after 48 and 96 of switching.

RESUMO

El objetivo del estudio fue describir los niveles de resistencia transmitida de VIH-1 en adultos atendidos en Unidades de Atención Integral de Guatemala. El estudio incluyó registros de 185 pacientes adultos VIH-1 positivo, de reciente diagnóstico sin antecedente de uso de TAR, de noviembre del 2019 a noviembre del 2020. El análisis se realizó en el software DeepChek® v2.0, para la clasificación de la resistencia se siguió el algoritmo de Stanford HIVdb (v9.4 - 07/12/2022). Se encontró 18.4% (IC 95% 13.1 - 24.7%) de resistencia general a alguna familia de ARVs. Se evidenció 15.1% (IC 95% 10.3 - 21.1%) de resistencia individual a la familia de INNTR afectando principalmente a NVP y EFV; 2.2% (IC 95% 0.6 - 5.4%) de resistencia a INTR, mayormente a FTC/3TC; y 2.7% (IC 95% 0.9 - 6.2%) de resistencia intermedia y baja los IP NFV y LPV/r. Tres casos presentaron resistencia múltiple a los INTR + INNTR. Las mutaciones más frecuentemente encontradas fueron K103N (41.2%), M184V/I (8.8%) y M46I (5.9%). La elevada resistencia transmitida del VIH-1 en pacientes atendidos en distintas Unidades de Atención Integral del VIH, demuestra la importancia de analizar periódicamente la tendencia de la resistencia en personas que no han estado expuestas a ARVs, lo cual a su vez es un marcador indirecto de presencia de resistencia adquirida en el país, datos que evidencian la necesidad de acciones e intervenciones prontas y efectivas dado su impacto en la salud pública.


The objective of this study was to describe the levels of transmitted HIV-1 resistance in patients with a recent HIV diagnosis before starting ART, treated in Comprehensive Care Units in Guatemala during the years 2019 and 2020. The study included records of 185 HIV-positive adult patients, recently diagnosed with HIV without a history of ART use. The analysis was carried out in the DeepChek® v2.0 software, the Stanford HIVdb algorithm (v9.4 - 07/12/2022) was followed to classify resistance. 18.4% (95% CI 13.1 - 24.7%) of general resistance to some family of ARVs was found. There was evidence of 15.1% (95% CI 10.3 - 21.1%) of individual resistance to the NNRTI family, mainly affecting NVP and EFV; 2.2% (95% CI 0.6 - 5.4%) resistance to INTR, mostly to FTC/3TC; and 2.7% (95% CI 0.9 - 6.2%) of intermediate and low resistance IP NFV and LPV/r. Three cases presented multiple resistance to NRTIs + NNRTIs. The most frequently found mutations were K103N (41.2%), M184V/I (8.8%) and M46I (5.9%). The high transmitted resistance of HIV-1 in patients treated in different Comprehensive HIV Care Units demonstrates the importance of periodically analyzing the trend of resistance in people who have not been exposed to ARVs, which in turn is an indirect marker. of the presence of acquired resistance in the country, data that demonstrate the need for prompt and effective actions and interventions given its impact on public health.

RESUMO

Sporadic Parkinson's disease, characterised by a decline in dopamine, usually manifests in people over 65 years of age. Although 10% of cases have a genetic (familial) basis, most PD is sporadic. Genome sequencing studies have associated several genetic variants with sporadic PD. Our aim was to analyse the promoter region of the ATG16L1 and ATG5 genes in sporadic PD patients and ethnically matched controls. Genotypes were obtained by using the Sanger method with primers designed by us. The number of haplotypes was estimated with DnaSP software, phylogeny was reconstructed in Network, and genetic divergence was explored with Fst. Seven and two haplotypes were obtained for ATG16L1 and ATG5, respectively. However, only ATG16L1 showed a significant contribution to PD and a significant excess of accumulated mutations that could influence sporadic PD disease. Of a total of seven haplotypes found, only four were unique to patients sharing the T allele (rs77820970). Recent studies using MAPT genes support the notion that the architecture of haplotypes is worthy of being considered genetically risky, as shown in our study, confirming that large-scale assessment in different populations could be relevant to understanding the role of population-specific heterogeneity. Finally, our data suggest that the architecture of certain haplotypes and ethnicity determine the risk of PD, linking haplotype variation and neurodegenerative processes.

RESUMO

Renal involvement in systemic lupus erythematosus (SLE) represents one of the most frequent organ manifestations, often leading to end-stage kidney disease (ESKD). Several therapies have been tested in patients with lupus nephritis (LN) to prevent further organ damage. The effectiveness of immunosuppressive therapy as a treatment for LN is abundant, supported by multiple clinical trials that have shown its efficacy in preventing the development of chronic kidney disease (CKD). In addition to immunosuppressive therapy, several traditional and recent therapies aimed at nephroprotection in patients with proteinuric chronic kidney disease are gaining importance in the setting of LN. Thus, immunosuppressive therapy should be accompanied by nephro- and cardioprotective measures to control cardiovascular risk factors and proteinuria to ensure a better renal prognosis. Despite this, the literature on these specific measures is relatively scarce, with recommendations focused on the blockade of the renin-angiotensin-aldosterone system (RAAS). This review explores the pharmacological options available for cardiovascular and renal protection outside the usual treatment schemes.

RESUMO

Objetivo: Identificar percepciones en cuanto a sesgos de género en la reumatología española y cuantificar la implicación de ambos sexos en todos los ámbitos de la especialidad. Métodos: Se envió una encuesta a todos los miembros de la SER, sobre participación y percepción de sesgos y de la propia capacitación y se revisaron los datos reales de participación en órganos directivos, congresos, comités y de los servicios de reumatología españoles en los últimos cinco años. Resultados: La encuesta fue respondida por 95 personas, 4,8% de los miembros de la SER (14 hombres y 81 mujeres). No se detectaron diferencias por sexo en edad, nivel académico, puesto, centro de trabajo, reparto de tareas laborales y del ámbito familiar; tampoco en las invitaciones a puestos de poder en los cinco últimos años, ni en la percepción de capacidad para ocupar los distintos puestos de poder. Los hombres encuestados consideran con mayor frecuencia que actividades como la participación en un comité científico o dar una ponencia no dan poder. Un tercio de los participantes de ambos sexos considera que la SER debería revisar sus procesos con perspectiva de género y menos de un tercio cree que debe hacerse por cuotas. Tras revisar los datos de 2015 a 2020, los ratios hombre a mujer en las principales actividades de liderazgo en reumatología en España son: 1) juntas directivas de la SER 3:2 sin presidenta ni tesorera; 2) comités científicos de los congresos 2:1; 3) ponentes y moderadores: simposios satélites, 4:1; 4) editores jefes de revistas científicas 9:1; 5) puestos académicos global 1,7:1, catedráticos 9:1, profesores titulares 100% hombres y 6) jefes de servicio: 75% son hombres a pesar de representar 40% de reumatólogos en España. Conclusión: A pesar de un creciente número de mujeres en la reumatología española, estas no están suficientemente representadas en puestos de liderazgo, existiendo un sesgo de género no percibido.(AU)


Objective: To identify perceptions of gender bias in Spanish rheumatology and to quantify the involvement of both sexes in all areas of the specialty. Methods: A survey was sent to all members of the SER on participation and perception of biases and of their own competencies, and actual data on participation in governing bodies, congresses, committees, and Spanish rheumatology departments in the last 5 years were reviewed. Results: The survey was answered by 95 rheumatologist, 4.8% of SER members (14 men and 81 women), both groups being similar in terms of age, academic level, and position and work centre. No differences were detected in the distribution of work and non-work tasks between sexes, nor in invitations to positions of power in the last five years, nor in the perception of capacity to occupy the different positions of power, which was high for both sexes. Male respondents more frequently consider that activities such as participating in a scientific committee or giving a conference are not empowering. A third of both sexes consider that the SER should review its processes with a gender perspective but less than a third believe that this should be done by quotas. The reality of the last 5 years is that 1) there is a male to female ratio of 3:2 on SER boards of directors and in this period there has been no female president or treasurer; 2) in the scientific committees of the congresses men predominate (2:1) although slightly less in the local organizing committee; 3) there are more male speakers and moderators than women (very striking in satellite symposia, 4: 1); 4) 9 out of 10 editors-in-chief are men; 5) in academic positions there are 3 men for every 2 women, 9 to 1 in professorships or emeritus positions; although more women supervise residents; and 6) there are more women (60%) than men (40%) in Spanish rheumatology departments, although 75% of department chiefs are men. Conclusion: Although not perceived by either the men or the women...(AU)

RESUMO

The present work revisits how artificial intelligence, as technology and ideology, is based on the rational choice theory and the techno-liberal discourse, supported by large corporations and investment funds. Those that promote using different algorithmic processes (such as filter bubbles or echo chambers) create homogeneous and polarized spaces that reinforces people's ethical, ideological, and political narratives. These mechanisms validate bubbles of choices as statements of fact and contravene the prerequisites for exercising deliberation in pluralistic societies, such as the distinction between data and values, the affirmation of reasonable dissent, and the relevance of diversity as a condition indispensable for democratic deliberation.

RESUMO

Since its emergence, HIV has been linked to metabolic alterations with an impact on the distribution of fat and the weight of people living with HIV. While extreme weight loss and processes such as lipodystrophy were of concern at first, in recent years, and with the appearance of increasingly effective and better tolerated drugs, an abnormal weight gain is paradoxically taking place among people living with HIV. Although this weight gain is a multifactorial process in which lifestyle habits, physical exercise or diet have a great impact, antiretroviral treatment has been recently considered as one of the key causes of this increase according to different clinical trials and real-life cohorts. The use of integrase inhibitors, specifically dolutegravir or bictegravir, and being female and/or from African/American origin appear to contribute to weight gain. In contrast, drugs such as tenofovir disoproxil fumarate would be protective factors. Even though different mechanisms of action have been proposed by which these agents would cause weight gain, the exact processes remain unclarified. Efforts are currently focused on knowing not only these mechanisms, but, more importantly, on finding the clinical relevance that this abnormal weight gain could have in other pathologies such as diabetes or cardiovascular events.

RESUMO

BACKGROUND: Schizophrenia (SCZ) is caused by an interplay of polygenic risk and environmental factors, which may alter regulators of gene expression leading to pathogenic misexpression of SCZ risk genes. The CPEB family of RNA-binding proteins (CPEB1-4) regulates translation of target RNAs (approximately 40% of overall genes). We previously identified CPEB4 as a key dysregulated translational regulator in autism spectrum disorder (ASD) because its neuronal-specific microexon (exon 4) is mis-spliced in ASD brains, causing underexpression of numerous ASD risk genes. The genetic factors and pathogenic mechanisms shared between SCZ and ASD led us to hypothesize CPEB4 mis-splicing in SCZ leading to underexpression of multiple SCZ-related genes. METHODS: We performed MAGMA-enrichment analysis on Psychiatric Genomics Consortium genome-wide association study data and analyzed RNA sequencing data from the PsychENCODE Consortium. Reverse transcriptase polymerase chain reaction and Western blot were performed on postmortem brain tissue, and the presence/absence of antipsychotics was assessed through toxicological analysis. Finally, mice with mild overexpression of exon 4-lacking CPEB4 (CPEB4Δ4) were generated and analyzed biochemically and behaviorally. RESULTS: First, we found enrichment of SCZ-associated genes for CPEB4-binder transcripts. We also found decreased usage of CPEB4 microexon in SCZ probands, which was correlated with decreased protein levels of CPEB4-target SCZ-associated genes only in antipsychotic-free individuals. Interestingly, differentially expressed genes fit those reported for SCZ, specifically in the SCZ probands with decreased CPEB4-microexon inclusion. Finally, we demonstrated that mice with mild overexpression of CPEB4Δ4 showed decreased protein levels of CPEB4-target SCZ genes and SCZ-linked behaviors. CONCLUSIONS: We identified aberrant CPEB4 splicing and downstream misexpression of SCZ risk genes as a novel etiological mechanism in SCZ.

RESUMO

OBJECTIVE: In this review, we examined if there is a deficit in facial recognition of emotion (FER) in children, adolescents, and adults with attention deficit hyperactivity disorder (ADHD). BACKGROUND: Emotional regulation is impaired in ADHD. Although a facial emotion recognition deficit has been described in this condition, the underlying causal mechanisms remain unclear. METHODS: The search was performed in six databases in September 2022. Studies assessing children, adolescents, or adults with isolated or comorbid ADHD that evaluated participants using a FER task were included. RESULTS: Twelve studies out of 385 were selected, with participants ranging in age from 6 to 37.1 years. A deficit in FER specific to ADHD, or secondary to comorbid autism spectrum disorder, anxiety, and oppositional symptoms, was found. CONCLUSIONS: There is a FER deficit in patients with ADHD. Adults showed improved recognition accuracy, reflecting partial compensation. ADHD symptoms and comorbidities appear to influence FER deficits.

RESUMO

BACKGROUND: To understand the effects of frailty, geriatric syndromes, and comorbidity on quality of life and mortality in older adults with HIV (OAWH). METHODS: Cross-sectional study of the FUNCFRAIL multicenter cohort. The setting was outpatient HIV-Clinic. OAWH, 50 year or over were included. We recorded sociodemographic data, HIV infection-related data, comorbidity, frailty, geriatric syndromes (depression, cognitive impairment, falls and malnutrition), quality of life (QOL) and the estimated risk of all-cause 5-year mortality by VACS Index. Association of frailty with geriatric syndromes and comorbidity was evaluated using the Cochran-Mantel-Haenszel test. RESULTS: Seven hundred ninety six patients were included. 24.7% were women, mean age was 58.2 (6.3). 14.7% were 65 or over. 517 (65%) patients had ≥3 comorbidities, ≥ 1 geriatric syndrome and/or frailty. There were significant differences in the estimated risk of mortality [(frailty 10.8%) vs. (≥ 3 comorbidities 8.2%) vs. (≥ 1 geriatric syndrome 8.2%) vs. (nothing 6.2%); p = 0.01] and in the prevalence of fair or poor QOL [(frailty 71.7%) vs. (≥ 3 comorbidities 52%) vs. (≥ 1 geriatric syndrome 58.4%) vs. (nothing 51%); p = 0.01]. Cognitive impairment was significantly associated to mortality (8.7% vs. 6.2%; p = 0.02) and depression to poor QOL [76.5% vs. 50%; p = 0.01]. CONCLUSIONS: Frailty, geriatric syndromes, and comorbidity had negative effects on mortality and QOL, but frailty had the greatest negative effect out of the three factors. Our results should be a wake-up call to standardize the screening for frailty and geriatric syndromes in OAWH in the clinical practice. TRIAL REGISTRATION: NCT03558438.

RESUMO

INTRODUCTION: This post hoc analysis evaluated influenza adverse events (AEs) across rheumatoid arthritis (RA), ulcerative colitis (UC), and psoriatic arthritis (PsA) tofacitinib clinical programs. METHODS: Available data from phase 1, randomized phase 2/3/3b/4 clinical trials (completed by 2018), and long-term extension (LTE) studies (up to May 2019) in patients with RA, UC, and PsA were included [randomized or Overall (phase 1-3b/4 and LTE studies) tofacitinib cohorts]. Incidence rates (IRs; events per 100 patient-years) of combined influenza AEs (seasons 2004/2005 to 2018/2019) were analyzed, including by tofacitinib dose [5 or 10 mg twice daily (BID)] and age (< 65 versus ≥ 65 years). Logistic regression models evaluated risk factors for influenza AEs in the RA Overall tofacitinib cohort. RESULTS: In randomized cohorts, combined influenza AE IRs were generally similar across tofacitinib, adalimumab, methotrexate, and placebo groups, across indications. Among Overall tofacitinib cohorts, combined influenza AE IRs with tofacitinib 5/10 mg BID, respectively, were higher in the UC (3.66/5.09) versus RA (2.38/2.19) and PsA (1.74/1.29) cohorts. IRs were generally similar across tofacitinib dose and age groups. Most influenza AEs were nonserious and did not require changes to tofacitinib treatment. Significant risk factors for influenza AEs in patients with RA were geographic region, baseline oral corticosteroid and methotrexate use, and tofacitinib dose. CONCLUSIONS: In the RA, UC, and PsA clinical programs, combined influenza AE IRs were highest in UC, while in each indication they were generally similar across tofacitinib, placebo, and comparator groups. Influenza AEs were predominantly nonserious and not associated with changes to tofacitinib treatment.

RESUMO

OBJECTIVES: To apply the lupus low disease activity state (LLDAS) definition within a large cohort of patients and to assess the agreement between the LLDAS and the physician's subjective evaluation of lupus activity. METHODS: We conducted a cross-sectional analysis of a prospective multicentre study of SLE patients. We applied the LLDAS and assessed whether there was agreement with the clinical status according to the physician's opinion. RESULTS: A total of 508 patients [92% women; mean age 50.4 years (s.d. 3.7)] were recruited and 304 (62.7%) patients were in the LLDAS. According to physician assessment, 430 (86.1%) patients were classified as remission or low activity. Overall agreement between both evaluations was 71.4% (95% CI: 70.1, 70.5) with a Cohen's κ of 0.3 [interquartile range (IQR) 0.22-0.37]. Most cases (96.1%) in the LLDAS were classified as remission or low activity by the expert. Of the patients who did not fulfil the LLDAS, 126 (70.4%) were classified as having remission/low disease activity. The main reasons for these discrepancies were the presence of new manifestations compared with the previous visit and a SLEDAI 2K score >4, mainly based on serological activity. CONCLUSIONS: Almost two-thirds of SLE patients were in the LLDAS. There was a fair correlation between the LLDAS and the physician's evaluation. This agreement improves for patients fulfilling the LLDAS criteria. The discordance between both at defining lupus low activity, the demonstrated association of the LLDAS with better outcomes and the fact that the LLDAS is more stringent than the physician's opinion imply that we should use the LLDAS as a treat-to-target goal.

RESUMO

The objectives of this study were to evaluate and compare the prevalence of health-related quality of life and depressive symptomatology in high school students during the lockdown period due to the SARS-CoV-2 pandemic. A cross-sectional survey was conducted with students attending the High School Education System of the University of Guadalajara, Jalisco, México. Through a Google Forms survey, students answered their perceptions of health-related quality of life and depressive symptomatology. The outcome variable was the presence of depressive symptoms, assessed using the Children's Depression Inventory (CDI). Cronbach's alpha coefficient was 0.8 in both surveys. A total of 1446 students participated (women, 64.9%; mean age of 16.1 ± 0.9 years). Among the students, 22% manifested clinical depressive symptoms (24.4 ± 5.0), and males showed lower scores on health-related quality of life and depressive symptoms (44.9 ± 11.9, p = 0.005) (12 ± 7.7, p = <0.001) compared to their female peers (45.2 ± 10.6, p = 0.005) (13.7 ± 7.5, p = <0.001), respectively. During the lockdown due to the SARS-CoV-2 pandemic, a high prevalence of depressive symptomatology was identified in our students with in addition to a low perception of health-related quality of life in dimensions, mood and emotions, and peers and social support.
