No full textPresent and future of HIV pre-exposure prophylaxis: a narrative review
No full textIntroduction: Pre-exposure prophylaxis (PrEP) has revolutionized HIV prevention, reducing the risk of transmission among at-risk populations. However, challenges remain in ensuring accessibility and adherence. Recent innovations, including long-acting injectable and implantable formulations, offer promising alternatives to daily oral regimens. Areas Covered: This narrative review examines the evolution of PrEP, covering tenofovir-based oral regimens, long-acting cabotegravir, lenacapavir, and dapivirine ring, as well as alternative delivery methods, including microneedle patches, rectal douches, and subdermal implants. We conducted a comprehensive literature search of clinical trials, real-world studies, and guidelines from major health organizations to assess the efficacy, safety, and implementation strategies of the intervention. Expert Opinion: While PrEP innovations enhance HIV prevention, their impact depends on accessibility, adherence support, and integration into public health programs. Long-acting formulations reduce adherence burdens but require strategic implementation and a robust organizational structure. Expanding provider involvement and addressing social and structural barriers will be crucial to optimizing PrEP uptake. Future research should prioritize equitable access, real-world effectiveness, and combined prevention strategies to accelerate progress toward the elimination of HIV
Tuberculosis-Induced Immune-Mediated Necrotizing Myopathy: A Challenging Case Scenario in a Non-Endemic Country
No full textBackground and Clinical Significance: Tuberculosis (TB) poses a significant global health challenge; although low–middle income countries carry the heaviest burden, its diagnosis and treatment can be challenging in any country. The clinical picture can be complex and vary from person to person, with autoimmune complications that can hinder TB diagnosis and treatment. Case Presentation: We report the case of a 38-year-old man from Bangladesh who had recently arrived in Italy through the Balkan route. He presented with TB in the cervical lymph nodes and long-standing chronic myalgias. While a wide range of TB-triggered autoimmune entities can be found in the literature, this case is the first to describe immune-mediated necrotizing myopathy (IMNM) triggered by active TB. Conclusions: IMNM has been previously associated only with other infections like SARS-CoV-2 and Dengue. The successful diagnosis and management of TB-induced IMNM was achieved through a collaborative, multidisciplinary approach involving rheumatologists, immunologists, and infectious diseases specialists, showcasing an innovative treatment strategy and adding new insights into the complexities of TB and IMNM
Sexually Transmitted Infections Prevalence and Cascade of Care among Undocumented Sex Workers: A Twenty-Year-Long Experience
Full text linkUndocumented migrant sex-workers (SW) are vulnerable to Sexually Transmitted Infections (STIs). However, data regarding prevalence and linkage-to-care are lacking. Defining epidemiology is crucial to implement preventive measures. We report data from SW attending a facility for migrants in Piacenza, Italy. We collected medical records from 1999 until 2021. Quantitative variables were summarized as mean and standard deviation (SD), and qualitative ones by absolute and relative frequencies. Logistic regression analysis was performed to assess the relationship between sociodemographic, clinical variables, positive testing, and loss to follow-up (LFU). Overall, 1035 STI episodes were collected, 917 in cisgender-females (CF), and 118 in transgender-females (TF). Overall, 474 diagnoses were made. Three-hundred-ninety-two/474 (82.7%) started therapy, and 264/474 (55.7%) complied with a follow-up. Only 51.5% of HBV and 30.8% of HIV were linked to care. Having symptoms (OR 1.70 (95% CI 1.06–2.73), p = 0.028) and previous STIs (OR 1.36 (95% CI 1.04–1.77), p = 0.022) were associated with a higher chance of STIs, while at-risk intercourse to lower risk (OR 0.19 (95% CI 0.07–0.49), p = 0.001). TF had higher odds of bloodborne infections and syphilis (OR 2.61 (95% CI 1.17–5.80), p = 0.019). Regarding follow-up, the older the patient, the higher the LFU (OR 1.05 (95% CI 1.01–1.10), p = 0.021). Our data showed a high prevalence of STIs and LFU among undocumented SW. TF are even more vulnerable. Further efforts should be put into targeted interventions
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
