Background A key-population approach to sexually transmitted disease prevention does not fully take into account the multidimensional nature of sexual risk behavior. Visits to sexual health centers for HIV/STI screening provide an opportunity to spread prevention messages and tools, but few data are available on patients’ sexual and prevention behaviors. This study aimed to identify the profile of patients consulting for HIV/STI testing in a Parisian sexual health center. Methods This observational study included 5,130 patients who attended the center for HIV/STI testing from August 2017 through January 2020 and completed a self-administered electronic questionnaire. Data were obtained from the consultation database and the questionnaire. The data included STI results, sociodemographic characteristics, sexual and prevention behaviors, as well as HIV knowledge. To identify homogeneous groups of patients regarding sexual risky behavior, we conducted a mixed approach including both a priori classification and agglomerative hierarchical clustering (AHC) based on multiple correspondence analysis (MCA). Sexual behaviors and substance use were included in the MCA. Results Median age of patients was 26 years [Q1–Q3:23–32]. Seven clusters of patients were identified. Two clusters had a high HIV/STI positivity rate (15–19%) with very different profiles: cluster 1 included socially disadvantaged patients who had no health insurance and cluster 5 included 89% of men who have sex with men. Two clusters had an HIV/STI positivity rate corresponding to that observed in the overall study population (10–11%) but exhibited risky behaviors (cluster 7 with a high frequency of unprotected sexual intercourse, substance use, cannabis use and weekly binge drinking) or lack of knowledge on HIV (cluster 6 including 100% of patients having transactional sex). Conclusions The multidimensional approach demonstrated that both key populations and lower-risk populations visit a sexual health center. While several groups could benefit from tailored interventions, knowledge of HIV and its treatment should be enhanced for every patient visiting a sexual health center. To provide a complete offer in sexual health, patients’ profiles and expectations need to be taken into account.

In patients with heart failure, some organizational and modifiable factors could be prognostic factors. We aimed to assess the association between the in-hospital care pathways during hospitalization for acute heart failure and the risk of readmission. This retrospective study included all elderly patients who were hospitalized for acute heart failure at the Universitary Hospital Lariboisière (Paris) during 2013. We collected the wards attended, length of stay, admission and discharge types, diagnostic procedures, and heart failure discharge treatment. The clinical factors were the specific medical conditions, left ventricular ejection fraction, type of heart failure syndrome, sex, smoking status, and age. Consistent groups of in-hospital care pathways were built using an ascending hierarchical clustering method based on a primary components analysis. The association between the groups and the risk of readmission at 1 month and 1 year (for heart failure or for any cause) were measured via a count data model that was adjusted for clinical factors. This study included 223 patients. Associations between the in-hospital care pathway and the 1 year-readmission status were studied in 207 patients. Five consistent groups were defined: 3 described expected in-hospital care pathways in intensive care units, cardiology and gerontology wards, 1 described deceased patients, and 1 described chaotic pathways. The chaotic pathway strongly increased the risk (p = 0.0054) of 1 year readmission for acute heart failure. The chaotic in-hospital care pathway, occurring in specialized wards, was associated with the risk of readmission. This could promote specific quality improvement actions in these wards. Follow-up research projects should aim to describe the processes causing the generation of chaotic pathways and their consequences.

Background Screening, condom use and post-exposure prophylaxis (PEP) are among existing HIV prevention strategies. However, efficient use of these strategies requires that patients have an adequate knowledge of HIV transmission routes and awareness of risk behaviors. This study aimed to assess knowledge about HIV transmission among patients who attended a free HIV and sexually transmitted infection (STI) screening center in Paris, France, and to explore the patient profiles associated with HIV-related knowledge. Methods This observational cross-sectional study included 2002 patients who attended for STI testing from August 2017 through August 2018 and completed a self-administered electronic questionnaire. Based on incorrect answers regarding HIV transmission, two outcomes were assessed: lack of knowledge and false beliefs. Factors associated with these two outcomes were explored using univariate and multivariate logistic regressions. Results Only 3.6% of patients did not know about HIV transmission through unprotected sexual intercourse and/or by sharing needles. More than one third of patients (36.4%) had at least one false belief, believing that HIV could be transmitted by sharing a drink (9.7%), kissing (17.6%) or using public toilets (27.5%). A low educational level and no previous HIV testing were associated in multivariate analyses with both lack of knowledge and false beliefs. Age and sexual orientation were also associated with false beliefs. Furthermore, 55.6% of patients did not know that post-exposure prophylaxis consists of taking emergency treatment as soon as possible after risky intercourse. Conclusions Although the main HIV transmission routes are well known, false beliefs persist and knowledge regarding PEP needs to be improved. Prevention campaigns must focus on these themes which appear as a complementary strategy to pre-exposure prophylaxis to reduce HIV infection.

Spinal cord injury and traumatic brain injury are major causes of long-term disability and are often complicated by spasticity, a motor disorder characterized by increased muscle tone and exaggerated reflexes that significantly impair quality of life. Current diagnostic methods lack the sensitivity needed to accurately predict the severity of injury or the onset and progression of spasticity. Trauma-induced calcium dysregulation activates calpains, a family of proteases that cleave sodium channels, disrupting their inactivation and increasing persistent sodium currents. This cascade drives the overexcitability of motoneurons, contributing to the development of spasticity. Consequently, sodium channel fragments have emerged as promising biomarkers that link injury mechanisms to clinical outcomes. The present SpasT-SCI-T clinical trial protocol aims to evaluate sodium channel fragments as blood biomarkers for assessing the severity of spinal cord and traumatic brain injuries, as well as their potential to predict clinical outcomes, including the development of spasticity. This prospective, multicenter, case-control and cohort study involves 40 participants: 20 individuals with spinal cord injury, 10 individuals with traumatic brain injury, and 10 healthy controls. Blood samples are collected within six hours of injury and at follow-up points over six months. Clinical outcomes, including spasticity (assessed using the Modified Ashworth Scale), neurological recovery (measured by the American Spinal Injury Association Impairment Scale and Glasgow Coma Scale), and quality of life (evaluated using the Short Form-36 Health Survey), are analyzed in correlation with biomarker levels. We anticipate that calpain-mediated sodium channel fragments will transform the management of central nervous system injuries by enabling early diagnosis, improving prognostic accuracy, and guiding personalized therapeutic strategies. The clinical trial is registered on ClinicalTrials.gov (NCT06532760, January 10, 2024), with Assistance Publique–Hôpitaux de Marseille as the sponsor.

HIV pre-exposure prophylaxis (PrEP) is highly effective but depends on patients’ care engagement, which is often mediocre and poorly measured in real-world settings. This study aimed to assess the effectiveness of a PrEP program in a sexual health center that included accompanying measures to improve engagement. A retrospective observational study was conducted. All men who have sex with men (MSM) who initiated PrEP for the first time between 1 August 2018 and 30 June 2019 in the Fernand-Widal sexual health center, Paris, France, were included. Among the 125 MSM who initiated PrEP, the median age was 33 and most had only male partners. At initiation, 58% were considered at very high risk of HIV infection, mainly due to a history of post-exposure prophylaxis. During the first year, patients attended a median of three visits (Q1–Q3, 2–4). At 12 months, 96% (95% CI, 92.6 to 99.4) had a successful PrEP course, assessed by a novel metric. These results highlight the possibility of achieving a high PrEP success ratio among MSM in a real-world setting. The accompanying measures and one-on-one counseling by a trained counselor could explain the effectiveness of this PrEP program.

BACKGROUNDText messaging after sexually transmitted infection (STI)/HIV screening may be a cost-effective means of improving patient care, but it may not be appropriate for all patients. This study aimed to explore the profiles of patients who did not participate in a short message service (SMS) program after STI/HIV testing. METHODSIn October 2016, 396 patients in Paris were screened for STI/HIV and were invited to complete an anonymous self-administered questionnaire. Patients were offered the possibility of being notified by SMS after testing, 68% accepted (SMS group) and 32% did not (no-SMS group). Each of the 100 patients from the no-SMS group who had completed the questionnaire was matched with the next patient from the SMS group. Factors associated with nonparticipation in the SMS program were studied using conditional logistic regression models. RESULTSParticipation in the SMS program was not related to STI screening characteristics (screening results and seriousness of the diseases screened) but seemed to be related to patient characteristics. In multivariate analysis, compared with patients in the SMS group, those in the no-SMS group were more often older, socially less favored (born in Africa or Asia, no university diploma, living outside Paris). They also more often declined to answer sexual questions, which could reflect a need for privacy and discretion. CONCLUSIONSAlthough SMS after STI/HIV screening is well accepted, it does not suit all patients. Several contact options should be proposed to comply with patientsʼ preferences and to reduce the risk of nondelivery of STI screening results.

BackgroundThe traditional retrosigmoid (RS) approach provides limited exposure of the inferior compartment of the CPA, while radical skull base approaches are demanding and associated with significant morbidity.MethodsThis study outlines the relevant surgical anatomy and the different surgical steps of a modified retrosigmoid (MRS) approach.ResultsThe MRS provides enhanced exposure of the CPA and deep vascular structures resulting from a modified RS craniotomy and limited exposure of the sigmoid sinus.ConclusionIn selected posterior fossa lesions, this cisternal approach is a straightforward corridor that can be routinely performed as a safe alternative to radical cranial base approaches.

Background Some patients who test positive for sexually transmitted infections (STIs) fail to return for results and treatment. To target improvement actions, we need to find out who these patients are. This study aimed to explore factors associated with failure to return within 30 days (FTR30) after testing among patients with positive results in a free STI testing centre in Paris. Methods All patients with at least one positive result between October 2016 and May 2017 and who completed a self-administered questionnaire were included in this cross-sectional study ( n  = 214). The questionnaire included sociodemographic factors, sexual behaviour and history of testing. Factors associated with FTR30 were assessed using logistic regression models. Results More than two-thirds of patients were men (72%), and the median age of patients was 27 years. Most patients were born in metropolitan France (56%) or in sub-Saharan Africa (22%). Men who had sex with men represented 36% of the study population. The FTR30 rate was 14% (95% CI [10–19%]). In multivariate analysis, previous HIV testing in younger persons (aOR: 3.36, 95% CI [1.27–8.84]), being accompanied by another person at the pretest consultation (aOR: 3.45, 95% CI [1.36–8.91]), and lower self-perceived risk of HIV infection (aOR: 2.79, 95% CI [1.07–7.30]) were associated with a higher FTR30. Testing for chlamydia/gonorrhoea without presumptive treatment was associated with a lower FTR30 (aOR: 0.21, 95% CI [0.07–0.59]). Conclusions These factors that affect failure to return are related to the patient’s representations and involvement in the STI screening process. Increasing health literacy and patient empowerment could help to decrease failure to return after being tested positive for HIV/STI. Trial registration Not applicable.

BackgroundPetroclival meningiomas are one of the most challenging tumors to be operated in the realm of neurosurgery. Many approaches have been developed over the years.MethodThe authors describe the Half & Half (H&H) approach whose main indication is petroclival meningiomas with suprasellar extension. The part of the tumor located above CN III and in the retrochiasmatic space is addressed through a trans-sylvian, while the petroclival portion is through an extradural anterior petrosectomy approach. The wide surgical corridor given by this approach allows extensive tumor resection while avoiding the risk associated with the manipulation of intracavernous neurovascular structures.ConclusionThe H&H approach is an effective strategy to maximize the safe resection of petroclival meningiomas.

Background Extradural disconnection of the cavernous sinus (CS) with preservation of the internal carotid artery (ICA) is indicated for aggressive and recurrent tumors, in patients presenting loss of oculomotor function and non-functional circle of Willis. Method Extradural resection of the anterior clinoid process disconnects the CS anteriorly. The ICA is dissected in the foramen lacerum via extradural subtemporal approach. The intracavernous tumor is split and removed following the ICA. Bleeding control of the inferior and superior petrosal and intercavernous sinuses completes posterior CS disconnection. Conclusion This technique can be proposed for recurrent CS tumors and need of ICA preservation.
