[PartnerREC network: Result from a process of coconstruction with patient partners and researchers]. / Réseau PartnerREC.

The PartnerREC network at the Geneva University Hospitals aims to facilitate the collaboration between researchers and patient partners in any type of clinical research, mainly those led at the HUG. It is the result of a coconstruction process initiated in 2019 by physicians, research professionals, cantonal research ethics committee members, a lawyer, and patient partners. The network implemented four initiatives: a) a website providing information to researchers and patients participating to research projects; b) personalized counseling for researchers to explore partnership opportunities in their own research projects; c) a training program related to patient partnership in research developed together with different partners in French-speaking Switzerland and d) its own research program on partnership in clinical research.

Le réseau PartnerREC des Hôpitaux universitaires de Genève a vu le jour afin de faciliter la collaboration entre les chercheur-ses et les patient-es partenaires dans tous les types de projets en recherche clinique, principalement ceux menés aux HUG. Il est le fruit d'une démarche de coconstruction débutée en 2019 par un groupe de médecins, chercheur-ses, membres de la Commission cantonale d'éthique de la recherche, une avocate et des patientes partenaires. Le réseau a mis en place 4 actions : a) la création d'un site internet destiné aux chercheur-ses et aux patient-es participant à des projets de recherche ; b) des conseils personnalisés pour accompagner les chercheur-ses dans leur démarche de partenariat ; c) une formation au partenariat en recherche, en collaboration avec des acteur-rices du partenariat en suisse romande et d) le développement de projets de recherche propres sur le partenariat patient-e en recherche.

[Sex and gender issues in the organisation of tomorrow's medicine]. / Enjeux de sexe et de genre dans l'organisation de la médecine de demain.

Medicine is evolving with increasing feminization and the rise of part-time work. Women now outnumber men among graduates but are underrepresented in leadership roles and in the highest-paid specialties. To meet these economic and organisational challenges, this article proposes a number of courses of action. In addition to an overall increase in the number of medical training places to compensate for retirement and the development of interprofessional integrated care structures, support for academic promotion and management positions for women, as well as an increase in the financial value of professional and non-remunerated activities, are all solutions to be considered. These changes will ensure that medicine is inclusive, efficient and of high quality.

La médecine évolue avec une féminisation croissante et l'émergence de nouveaux modes de travail. Les femmes sont majoritaires parmi les diplômé-es mais sous-représentées aux postes de cadres et dans les spécialités à plus haut revenus. Pour répondre à ces défis économiques et organisationnels, cet article propose des pistes d'actions. En plus d'une augmentation globale des places de formation médicale pour pallier les départs en retraite et du développement de structures interprofessionnelles de soins intégrés, un soutien aux promotions académiques et aux positions de cadres pour les femmes ainsi qu'une revalorisation financière des activités professionnelles et non rémunérées sont autant de solutions à envisager. Ces changements assureront une médecine inclusive, de plus grande efficience et de qualité.

The Maternal Psychic Impact of Infection by SARS-CoV-2 during Pregnancy: Results from a Preliminary Prospective Study.

Due to a higher risk of maternal complications during pregnancy, as well as pregnancy complications such as stillbirth, SARS-CoV-2 contamination during pregnancy is a putative stress factor that could increase the risk of perinatal maternal mental health issues. We included women older than 18 years, who delivered a living baby at the Geneva University Hospitals' maternity wards after 29 weeks of amenorrhea (w.a.) and excluded women who did not read or speak fluent French. We compared women who declared having had COVID-19, confirmed by a positive PCR test for SARS-CoV-2, during pregnancy with women who did not, both at delivery and at one month postpartum. We collected clinical data by auto-questionnaires between time of childbirth and the third day postpartum regarding the occurrence of perinatal depression, peritraumatic dissociation, and peritraumatic distress during childbirth, measured, respectively, by the EPDS (depression is score > 11), PDI (peritraumatic distress is score > 15), and PDEQ (scales). At one month postpartum, we compared the proportion of women with a diagnosis of postpartum depression (PPD) and birth-related posttraumatic stress disorder (CB-PTSD), using PCL-5 for CB-PTSD and using diagnosis criteria according DSM-5 for both PPD and CB-PTSD, in the context of a semi-structured interview, conducted by a clinician psychologist. Off the 257 women included, who delivered at the University Hospitals of Geneva between 25 January 2021 and 10 March 2022, 41 (16.1%) declared they had a positive PCR test for SARS-CoV-2 during their pregnancy. Regarding mental outcomes, except birth-related PTSD, all scores provided higher mean values in the group of women who declared having been infected by SARS-CoV-2, at delivery and at one month postpartum, without reaching any statistical significance: respectively, 7.8 (±5.2, 8:4-10.5) versus 6.5 (±4.7, 6:3-9), p = 0.139 ***, for continuous EPDS scores; 10 (25.0) versus 45 (21.1), p = 0.586 *, for dichotomous EPDS scores (≥11); 118 (55.7) versus 26 (63.4), p = 0.359 *, for continuous PDI scores; 18.3 (±6.8, 16:14-21) versus 21.1 (±10.7, 17:15-22), 0.231 ***, for dichotomous PDI scores (≥15); 14.7 (±5.9, 13:10-16) versus 15.7 (±7.1, 14:10-18), p = 0.636 ***, for continuous PDEQ scores; 64 (30.0) versus 17 (41.5), p = 0.151 *, for dichotomous PDEQ scores (≥15); and 2 (8.0) versus 5 (3.6), p = 0.289 *, for postpartum depression diagnosis, according DSM-5. We performed Chi-squared or Fisher's exact tests, depending on applicability for the comparison of categorical variables and Mann-Whitney nonparametric tests for continuous variables; p < 0.05 was considered as statistically significant. Surprisingly, we did not find more birth-related PTSD as noted by the PCL-5 score at one month postpartum in women who declared a positive PCR test for SARS-CoV-2:15 (10.6) versus no case of birth related PTSD in women who were infected during pregnancy (p = 0.131 *). Our study showed that mental outcomes were differently distributed between women who declared having been infected by SARS-CoV-2 compared to women who were not infected. However, our study was underpowered to explore all the factors associated with psychiatric issues during pregnancy, postpartum, depending on the exposure to SARS-CoV-2 infection during pregnancy. Future longitudinal studies on bigger samples and more diverse populations over a longer period are needed to explore the long-term psychic impact on women who had COVID-19 during pregnancy.

Multicentric evaluation of a specific intrathecal anti-Treponema pallidum IgG index as a diagnostic biomarker of neurosyphilis: results from a retro-prospective case-control study.

BACKGROUND AND OBJECTIVES: The diagnosis of neurosyphilis (NS) lacks a true 'gold standard', making the diagnosis challenging while consequences of a misdiagnosis are potentially severe. The aim of this study was to evaluate the diagnostic performance of measuring an antibody index (AI) for the intrathecal synthesis of specific anti-Treponema pallidum (T. pallidum) IgG for the diagnosis of NS. METHODS: Specific anti-T. pallidum IgG were measured simultaneously in paired cerebrospinal fluid (CSF)-serum samples collected retrospectively and prospectively between 2007 and 2022, from patients suspected of NS, in Switzerland. An AI was calculated to account for blood-brain barrier integrity. Area under the receiver operating characteristic curve, sensitivity/specificity and positive/negative predictive values of AI test were estimated. Two NS definitions were used: NS1 included patients with NS suspicion presenting with neurological symptoms and/or acute neurosensory signs, and positive T. Pallidum Hemagglutinations Assay (TPHA)/T. pallidum particle agglutination assay (TPPA) serology and CSF-TPHA/TPPA ≥320, and either CSF-leucocytes >5 cells/mm3 and/or CSF-protein >0.45 g/L and/or a reactive CSF-venereal disease research laboratory (VDRL)/rapid plasma reagin (RPR) test. NS2 included patients with suspected NS presenting with acute ocular and/or otologic symptoms, and positive TPHA/TPPA serology, and a favourable response to NS treatment. Controls were patients diagnosed with any other central nervous system (CNS) pathologies and with positive TPHA/TPPA serology. RESULTS: The study included 71 NS (43 NS1 and 28 NS2) and 110 controls. With a threshold of ≥1.7, sensitivity and specificity of the specific AI test were 90.7% (CI 77.7 to 97.4) and 100% (CI 96.7 to 100.0), respectively, for NS1 and 14.3% (CI 4 to 32.7) and 100% (CI 96.7 to 100.0) for NS2. In patients suspected of NS with a CNS involvement (NS1 group), NS could be confirmed by the positivity of this specific AI. CONCLUSIONS: Measurement of an intrathecal synthesis index of specific anti-T. pallidum IgG in patients with CSF inflammatory signs appears to be a valuable diagnostic test. However, in otic or ocular syphilis, presenting few CSF abnormalities, AI is not sufficient alone to confirm NS diagnosis.

In health research publications, the number of authors is strongly associated with collective self-citations but less so with citations by others.

OBJECTIVE: . This study investigated the associations between the number of authors and collective self-citations versus citations by others. STUDY DESIGN AND SETTING: . We analyzed 88,594 health science articles published in 2015 and citations they received until 2020. The main variables were the number of authors, the number of citations by co-authors (collective self-citations), and the number of citations by others. RESULTS: . The number of authors correlated more strongly with the number of citations by co-authors than with citations by others (Spearman r 0.31 vs. 0.23; mutually adjusted r 0.26 vs. 0.12). The percentage of self-citations among all citations was 10.6% for single-authored articles, and increased gradually with the number of authors to 34.8% for ≥ 50 authors. Collective self-citations increased the proportion of articles reaching or exceeding 30 total citations by 0.7% for single-authored articles, but by 11.6% for articles written by ≥ 50 authors. CONCLUSIONS: . If citations by others reflect scientific utility, then another mechanism must explain the excess of collective self-citations observed for multi-authored articles. The results support the hypothesis that the authors' own motivations explain this excess. The evaluation of scientific utility should also be based on citations by others, excluding collective self-citations.

Evidence of Lack of Treatment Efficacy Derived From Statistically Nonsignificant Results of Randomized Clinical Trials.

Importance: Many randomized clinical trials yield statistically nonsignificant results. Such results are difficult to interpret within the dominant statistical framework. Objective: To estimate the strength of evidence in favor of the null hypothesis of no effect vs the prespecified effectiveness hypothesis among nonsignificant primary outcome results of randomized clinical trials by application of the likelihood ratio. Design, Setting, and Participants: Cross-sectional study of statistically nonsignificant results for primary outcomes of randomized clinical trials published in 6 leading general medical journals in 2021. Outcome measures: The likelihood ratio for the null hypothesis of no effect vs the effectiveness hypothesis stated in the trial protocol (alternate hypothesis). The likelihood ratio quantifies the support that the data provide to one hypothesis vs the other. Results: In 130 articles that reported 169 statistically nonsignificant results for primary outcomes, 15 results (8.9%) favored the alternate hypothesis (likelihood ratio, <1), and 154 (91.1%) favored the null hypothesis of no effect (likelihood ratio, >1). For 117 (69.2%), the likelihood ratio exceeded 10; for 88 (52.1%), it exceeded 100; and for 50 (29.6%), it exceeded 1000. Likelihood ratios were only weakly correlated with P values (Spearman r, 0.16; P = .045). Conclusions: A large proportion of statistically nonsignificant primary outcome results of randomized clinical trials provided strong support for the hypothesis of no effect vs the alternate hypothesis of clinical efficacy stated a priori. Reporting the likelihood ratio may improve the interpretation of clinical trials, particularly when observed differences in the primary outcome are statistically nonsignificant.

Analysis of peer reviewers' response to invitations by gender and geographical region: cohort study of manuscripts reviewed at 21 biomedical journals before and during covid-19 pandemic.

OBJECTIVES: To describe gender and geographical inequalities in invitations to review and the response to these invitations and to assess whether inequalities increased during the covid-19 pandemic. DESIGN: Retrospective cohort study. SETTING: 19 specialist medical journals and two large general medical journals from BMJ Publishing Group. POPULATION: Reviewers invited to review manuscripts submitted between 1 January 2018 and 31 May 2021. The cohort was followed up to 28 February 2022. MAIN OUTCOME MEASURES: Reviewer's agreement to review. RESULTS: A total of 257 025 reviewers were invited (38.6% (88 454/228 869) women), and 90 467 (35.2%) agreed to review. Invited reviewers were mainly (217 682; 84.7%) affiliated with high income countries: Europe (122 414; 47.6%), North America (66 931; 26.0%), Africa (25 735; 10.0%), Asia (22 693; 8.8%), Oceania (16 175; 6.3%), and South America (3076; 1.2%). Independent factors associated with agreement to review were gender (odds ratio 0.89, 95% confidence interval 0.87 to 0.92, for women compared with men), geographical affiliation (2.89, 2.73 to 3.06, for Asia; 3.32, 2.94 to 3.75 for South America; 1.35, 1.27 to 1.43, for Oceania; and 0.35, 0.33 to 0.37, for Africa compared with Europe), and country income (0.47, 0.45 to 0.49, for upper middle income; 5.12, 4.67 to 5.61, for lower middle income; and 4.66, 3.79 to 5.73, for low income compared with high income country). Agreement was also independently associated with editor's gender (0.96, 0.93 to 0.99, for women compared with men), last author's geographical affiliation (0.80, 0.78 to 0.83, for Asia; 0.89, 0.85 to 0.94, for Oceania compared with Europe), impact factor (1.78, 1.27 to 2.50, for >10 compared with <5), and type of peer review process (0.52, 0.35 to 0.77, for open compared with anonymised). During the first and second phases of the pandemic, agreement was lower than in the pre-pandemic period (P<0.001). The interaction between time periods and covid-19 related topic and reviewer's gender was non-significant. However, significant interaction was found between time periods and covid-19 related topic and reviewer's geographical affiliation. CONCLUSIONS: To reduce bias and improve diversity, editors need to identify and implement effective strategies and continually evaluate progress against these to ensure that more women and researchers from upper middle income and low income countries are involved in review.

Trends in management and outcomes of COVID patients admitted to a Swiss tertiary care hospital.

Two successive COVID-19 flares occurred in Switzerland in spring and autumn 2020. During these periods, therapeutic strategies have been constantly adapted based on emerging evidence. We aimed to describe these adaptations and evaluate their association with patient outcomes in a cohort of COVID-19 patients admitted to the hospital. Consecutive patients admitted to the Geneva Hospitals during two successive COVID-19 flares were included. Characteristics of patients admitted during these two periods were compared as well as therapeutic management including medications, respiratory support strategies and admission to the ICU and intermediate care unit (IMCU). A mutivariable model was computed to compare outcomes across the two successive waves adjusted for demographic characteristics, co-morbidities and severity at baseline. The main outcome was in-hospital mortality. Secondary outcomes included ICU admission, Intermediate care (IMCU) admission, and length of hospital stay. A total of 2'983 patients were included. Of these, 165 patients (16.3%, n = 1014) died during the first wave and 314 (16.0%, n = 1969) during the second (p = 0.819). The proportion of patients admitted to the ICU was lower in second wave compared to first (7.4 vs. 13.9%, p < 0.001) but their mortality was increased (33.6% vs. 25.5%, p < 0.001). Conversely, a greater proportion of patients was admitted to the IMCU in second wave compared to first (26.6% vs. 22.3%, p = 0.011). A third of patients received lopinavir (30.7%) or hydroxychloroquine (33.1%) during the first wave and none during second wave, while corticosteroids were mainly prescribed during second wave (58.1% vs. 9.1%, p < 0.001). In the multivariable analysis, a 25% reduction of mortality was observed during the second wave (HR 0.75; 95% confidence interval 0.59 to 0.96). Among deceased patients, 82.3% (78.2% during first wave and 84.4% during second wave) died without beeing admitted to the ICU. The proportion of patients with therapeutic limitations regarding ICU admission increased during the second wave (48.6% vs. 38.7%, p < 0.001). Adaptation of therapeutic strategies including corticosteroids therapy and higher admission to the IMCU to receive non-invasive respiratory support was associated with a reduction of hospital mortality in multivariable analysis, ICU admission and LOS during the second wave of COVID-19 despite an increased number of admitted patients. More patients had medical decisions restraining ICU admission during the second wave which may reflect better patient selection or implicit triaging.

Clinicians' views regarding caesarean section rates in Switzerland: A cross-sectional web-based survey.

Objective: The caesarean section (CS) rate in Switzerland is currently 32 %, well above the WHO recommended rate of 15 %. The study aims were three-fold: to explore the perception of this high rate among Swiss obstetrics-gynecology (Ob-Gyn) professionals; to assess the factors associated with a perception of a too high national CS rate; and to describe professionals' opinions on measures to reduce this rate. Study design: A cross-sectional study was conducted between 1 May and 30 June 2021 using an online questionnaire sent to Ob/Gyn physicians and midwives at a university hospital and members of the Swiss Conference of Heads of Ob/Gyn Divisions. Survey participation was voluntary. The main outcome was the belief that CS was high. Associations were explored between different factors and the main outcome with logistic regression. Results were presented as odds ratios (OR) with 95 % confidence intervals (CIs). Multivariate logistic regression included adjustments for age, gender, place of work and profession. Results: Of 226 health professionals invited, 188 completed the questionnaire (83.2 % participation rate). Among respondents, 50.3 % (n = 94) were Ob/Gyn physicians and 49.7 % were midwives (n = 93); 77.1 % were women (n = 145). Most participants (74.7 % [n = 139]) considered the Swiss CS rate as too high and that it should be reduced (79 % [n = 147]) but, notably, they considered their own CS rate as correct (71.9 % [n = 123]). Improving patient education (57.5 % [n = 108]) and professional training (54.8 % [n = 103]) were considered as strategies to reduce this rate. In multivariate analysis, only length of professional experience was significantly associated with a higher likelihood of considering the CS rate as too high (OR 3.07, 95 % CI 1.01-9.30; p = 0.047). When specialty was added in the model, the length of professional experience disappeared and the perception of having a too high CS rate was associated with being a midwife and obstetrician rather than a gynecologist (OR 3.62, 95 % CI 1.72-7.63; p = 0.001). Conclusions: Clinicians, particularly obstetricians, believed that the current rate of CS in Switzerland was too high and that actions were needed to reduce this rate. Improving patient education and professional training were considered as the main strategies to be explored.

Epidemiology of high-energy blunt pelvic ring injuries: A three-year retrospective case series in a level-I trauma center.

BACKGROUND: High-energy pelvic ring injuries (PRI) represent a heavy burden for institutions treating severely injured patients. Epidemiological data knowledge may help to provide them appropriate management. Only two epidemiologic studies about high-energy PRI were published during last decade. This study aimed to determine the gender-specific and global incidences of high-energy blunt AO/OTA type B or C PRI and their frequency among high-energy blunt trauma. It further reports the spectrum of these injuries and compares their characteristics and outcomes to high-energy blunt trauma without type B or C PRI. HYPOTHESIS: Type B or C PRI incidence isn't gender specific and approximates 5/100,000/year. PATIENTS AND METHODS: A prospective database of a level-I trauma center serving approximately 500,000 inhabitants was retrospectively queried for all high-energy trauma patients injured between 01.01.2014 and 12.31.2016. Inclusion criteria were: alive emergency department delivery; entire acute treatment at the authors' institution; age >16. Exclusion criteria were: penetrating, blast, burn and electrical injuries; drownings; low-energy trauma; patients living outside the institution's catchment area. Three authors performed PRI classifications. Clinical data were extracted from the database. RESULTS: We analyzed 434 patients. High-energy blunt type B or C PRI incidence was 3.8/100,000/year without gender disparity (p=0.6697). High-energy blunt trauma incidence was lower in women than in men (20.5 vs. 51.6/100,000/year, p<0.001). Type B or C PRI frequency during high-energy blunt trauma was higher in women than in men (17.6% vs. 7.9%, p=0.003). Type B or C PRI patients were more severely injured and needed more treatment resources than other high-energy blunt trauma patients but didn't present higher complication or death rates. DISCUSSION: The incidence of high-energy blunt type B or C PRI was comparable to previously published data. Women were less likely to sustain a high-energy blunt trauma, but when they sustained one, they were more likely to have a type B or C PRI. Despite higher injury severity score and resource requirements, complication and death rates weren't different between type B or C PRI patients and other high-energy blunt trauma patients. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Traumatic Childbirth and Birth-Related Post-Traumatic Stress Disorder in the Time of the COVID-19 Pandemic: A Prospective Cohort Study.

BACKGROUND: Birth-related post-traumatic stress disorder occurs in 4.7% of mothers. No previous study focusing precisely on the stress factors related to the COVID-19 pandemic regarding this important public mental health issue has been conducted. However, the stress load brought about by the COVID-19 pandemic could have influenced this risk. METHODS: We aimed to estimate the prevalence of traumatic childbirth and birth-related PTSD and to analyze the risk and protective factors involved, including the risk factors related to the COVID-19 pandemic. We conducted a prospective cohort study of women who delivered at the University Hospitals of Geneva between 25 January 2021 and 10 March 2022 with an assessment within 3 days of delivery and a clinical interview at one month post-partum. RESULTS: Among the 254 participants included, 35 (21.1%, 95% CI: 15.1-28.1%) experienced a traumatic childbirth and 15 (9.1%, 95% CI: 5.2-14.6%) developed a birth-related PTSD at one month post-partum according to DSM-5. Known risk factors of birth-related PTSD such as antenatal depression, previous traumatic events, neonatal complications, peritraumatic distress and peritraumatic dissociation were confirmed. Among the factors related to COVID-19, only limited access to prenatal care increased the risk of birth-related PTSD. CONCLUSIONS: This study highlights the challenges of early mental health screening during the maternity stay when seeking to provide an early intervention and reduce the risk of developing birth-related PTSD. We found a modest influence of stress factors directly related to the COVID-19 pandemic on this risk.

Attitudes of university hospital staff towards in-house assisted suicide.

OBJECTIVE: To investigate staff attitudes toward assisted suicide in the hospital setting in Switzerland. DESIGN: Cross-sectional study. SETTING: Two University Hospitals in French speaking regions of Switzerland. PARTICIPANTS: 13'834 health care professionals, including all personnel caring for patients, were invited to participate. MAIN OUTCOME MEASURES AND OTHER VARIABLES: Attitudes towards the participation of hospital health care professionals in assisted suicide were investigated with an online questionnaire. RESULTS: Among all invited professionals, 5'127 responded by filling in the survey at least partially (response rate 37.0%), and 3'683 completed the entire survey (26.6%). 73.0% of participants approved that this practice should be authorized in their hospital and saw more positive than negative effects. 57.6% would consider assisted suicide for themselves. Non-medical professionals were 1.28 to 5.25 times more likely to approve assisted suicide than physicians (p<0.001). 70.7% of respondents indicated that each professional should have the choice of whether to assist in suicide. CONCLUSIONS: This multiprofessional survey sheds light on hospital staff perceptions of assisted suicide happening within hospital walls, which may inform the development of rules considering their wishes but also their reluctances. Further research using a mixed-methods approach could help reach an in-depth understanding of staff's attitudes and considerations towards assisted suicide practices.

Effectiveness of rib fixation compared to pain medication alone on pain control in patients with uncomplicated rib fractures: study protocol of a pragmatic multicenter randomized controlled trial-the PAROS study (Pain After Rib OSteosynthesis).

BACKGROUND: Persistent pain and disability following rib fractures result in a large psycho-socio-economic impact for health-care system. Benefits of rib osteosynthesis are well documented in patients with flail chest that necessitates invasive ventilation. In patients with uncomplicated and simple rib fractures, indication for rib osteosynthesis is not clear. The aim of this trial is to compare pain at 2 months after rib osteosynthesis versus medical therapy. METHODS: This trial is a pragmatic multicenter, randomized, superiority, controlled, two-arm, not-blinded, trial that compares pain evolution between rib fixation and standard pain medication versus standard pain medication alone in patients with uncomplicated rib fractures. The study takes place in three hospitals of Thoracic Surgery of Western Switzerland. Primary outcome is pain measured by the brief pain inventory (BPI) questionnaire at 2 months post-surgery. The study includes follow-up assessments at 1, 2, 3, 6, and 12 months after discharge. To be able to detect at least 2 point-difference on the BPI between both groups (standard deviation 2) with 90% power and two-sided 5% type I error, 46 patients per group are required. Adjusting for 10% drop-outs leads to 51 patients per group. DISCUSSION: Uncomplicated rib fractures have a significant medico-economic impact. Surgical treatment with rib fixation could result in better clinical recovery of patients with uncomplicated rib fractures. These improved outcomes could include less acute and chronic pain, improved pulmonary function and quality of life, and shorter return to work. Finally, surgical treatment could then result in less financial costs. TRIAL REGISTRATION: ClinicalTrials.gov NCT04745520 . Registered on 8 February 2021.

Comparison of prognostic scores for inpatients with COVID-19: a retrospective monocentric cohort study.

BACKGROUND: The SARS-CoV-2 pandemic led to a steep increase in hospital and intensive care unit (ICU) admissions for acute respiratory failure worldwide. Early identification of patients at risk of clinical deterioration is crucial in terms of appropriate care delivery and resource allocation. We aimed to evaluate and compare the prognostic performance of Sequential Organ Failure Assessment (SOFA), Quick Sequential Organ Failure Assessment (qSOFA), Confusion, Uraemia, Respiratory Rate, Blood Pressure and Age ≥65 (CURB-65), Respiratory Rate and Oxygenation (ROX) index and Coronavirus Clinical Characterisation Consortium (4C) score to predict death and ICU admission among patients admitted to the hospital for acute COVID-19 infection. METHODS AND ANALYSIS: Consecutive adult patients admitted to the Geneva University Hospitals during two successive COVID-19 flares in spring and autumn 2020 were included. Discriminative performance of these prediction rules, obtained during the first 24 hours of hospital admission, were computed to predict death or ICU admission. We further exluded patients with therapeutic limitations and reported areas under the curve (AUCs) for 30-day mortality and ICU admission in sensitivity analyses. RESULTS: A total of 2122 patients were included. 216 patients (10.2%) required ICU admission and 303 (14.3%) died within 30 days post admission. 4C score had the best discriminatory performance to predict 30-day mortality (AUC 0.82, 95% CI 0.80 to 0.85), compared with SOFA (AUC 0.75, 95% CI 0.72 to 0.78), qSOFA (AUC 0.59, 95% CI 0.56 to 0.62), CURB-65 (AUC 0.75, 95% CI 0.72 to 0.78) and ROX index (AUC 0.68, 95% CI 0.65 to 0.72). ROX index had the greatest discriminatory performance (AUC 0.79, 95% CI 0.76 to 0.83) to predict ICU admission compared with 4C score (AUC 0.62, 95% CI 0.59 to 0.66), CURB-65 (AUC 0.60, 95% CI 0.56 to 0.64), SOFA (AUC 0.74, 95% CI 0.71 to 0.77) and qSOFA (AUC 0.59, 95% CI 0.55 to 0.62). CONCLUSION: Scores including age and/or comorbidities (4C and CURB-65) have the best discriminatory performance to predict mortality among inpatients with COVID-19, while scores including quantitative assessment of hypoxaemia (SOFA and ROX index) perform best to predict ICU admission. Exclusion of patients with therapeutic limitations improved the discriminatory performance of prognostic scores relying on age and/or comorbidities to predict ICU admission.

Long-term follow-up for childhood cancer survivors: the Geneva experience.

AIMS OF THE STUDY: Although the 5-year survival for pediatric cancer in Switzerland today is over 85%, two thirds of the survivors will develop chronic health conditions due to the disease or to the toxicity of treatments. In this context, a long-term personalized follow-up program (LTFU program), was set up at the University Hospitals of Geneva (HUG) since 2015. We aimed to describe this program, more particularly the specialized follow-ups set up, the cumulative burden of the chronic health conditions, and finally assess the satisfaction of patients and/or their parents with it. METHODS: A monocentric retrospective study was performed where data on follow-ups and chronic health conditions were collected from medical charts of people who had childhood cancer and who participated in the LTFU program. Chronic health conditions were classified and graded in severity with the Common Terminology Criteria of Adverse Events (CTCAE) classification, version 5.0. This study was completed by a satisfaction survey among patients and/or their parents. RESULTS: Out of 83 eligible patients, 51 (61.4%) accepted to participate, with an average age of 17.4 years (range, 10 to 35) at the time of study. Mean delay since end of treatment was 9.8 years (range: 4.5-31). The prevalence of any chronic health condition is 82.3%, 43.1% for having 1 or 2 chronic health conditions and 39.2% for having more than 3 chronic health conditions. The total number of Grade CTCAE 1-4 chronic health conditions was 118 for the 51 participants, with a mean of 2.3 (range, 0 to 7) disorders per patient. The most frequently affected systems were neurological (14.4%), musculoskeletal (13.6%), endocrine (9.3%) and renal (9.3%) systems. Sarcoma, central nervous system tumors and neuroblastoma were the diagnoses associated with the highest average number of chronic health conditions. Among the 118 questionnaires sent to patients and/or parents, we received 82 (69.5%) responses. The level of satisfaction was good to excellent for more than 90% of the participants, for all the items evaluated. CONCLUSIONS: Childhood cancer survivors present a significant number of chronic health conditions, confirming the need for appropriate long-term, multidisciplinary and patient-specific medical follow-up based on the primary diagnosis and therapies received. Moreover, the LTFU program at the HUG was highly appreciated by patients and/or their parents and this motivates its permanent conduct.

Intrathecal Synthesis Index of Specific Anti-Treponema IgG: a New Tool for the Diagnosis of Neurosyphilis.

Neurosyphilis (NS) diagnosis is challenging because clinical signs are diverse and unspecific, and a sensitive and specific laboratory test is lacking. We tested the performance of an antibody index (AI) for intrathecal synthesis of specific anti-Treponema IgG by enzyme-linked immunosorbent assay (ELISA) for NS diagnosis. We conducted a retroprospective monocentric study including adults with neurological symptoms who had serum and cerebral spinal fluid (CSF) samples collected between 2006 and 2021. Two NS definitions were used. NS1 included patients with neurological symptoms, positive Treponema pallidum particle agglutination (TPPA) serology, and CSF-TPPA of ≥320, as well as CSF-leukocytes of >5 cells/mm3 and/or CSF-protein of >0.45 g/L and/or a reactive CSF-VDRL/RPR test. NS2 included patients with acute ocular and/or otologic symptoms, positive TPPA serology, and a response to NS treatment. Controls were patients with central nervous system disorders other than neurosyphilis. Anti-Treponema pallidum IgG were measured simultaneously in serum and CSF, and AI was calculated according to Reiber diagram. We assessed the AI test area under the curve (AUC), sensitivity/specificity, and estimated positive and negative predictive values. In total, 16 NS1 patients, 11 NS2 patients, and 71 controls were included. With an AI of ≥1.7 as a positive test for NS diagnostic, specificity was 98.6% (95% confidence interval [CI 95%] of 92.4 to 100.0) and sensitivity was 81.3% (CI 95% of 54.4 to 96.0) for NS1 and 98.6% (CI 95% 92.4 to 100.0) and 27.3% (CI 95% 6.0 to 61.0), respectively, for NS2. Positive and negative predictive values were >95% for NS1 and >85% for NS2, for prevalence above and below 20%. Measuring an AI for intrathecal synthesis of specific anti-Treponema pallidum IgG is a new promising tool highly specific for NS diagnosis. IMPORTANCE In the context of a lack of a gold standard for the diagnosis of neurosyphilis due to either nonspecific or nonsensitive tests, we present in this article a new promising tool highly specific for NS diagnosis. This new test involves measuring an intrathecal synthesis index of specific anti-Treponema IgG by ELISA.
