Surgery after sonidegib treatment achieves complete response in locally advanced basal cell carcinoma of the face.

Basal cell carcinoma accounts for 75% of skin cancers worldwide and is the most common malignancy in Caucasians. Since chronic ultraviolet exposure is the major risk factor for its development, sun-exposed areas such as the face are frequently affected. The gold-standard treatment is surgical excision. Radiotherapy may be considered in selected cases such as unresectable primary tumors. In some patients, when the risk of a significant functional/cosmetic deficit advises against both surgery and radiotherapy, target therapy (hedgehog pathway inhibitors) can be administered alone or in a neoadjuvant setting, to reduce the tumor size and make it eligible for surgery. Vismodegib as a neoadjuvant treatment before surgery has been investigated in a single, multicentre, open-label, phase II trial (VISMONEO); however, sonidegib has not yet been evaluated in this setting. We report the cases of two patients with locally advanced basal cell carcinoma of the face who achieved complete remission with sonidegib followed by a more limited surgical excision than would have been needed without target therapy.

"Test-To-PrEP": Assessing Reach and Adoption of a New Approach to Increase HIV Testing and PrEP Knowledge Using HIV Self-Test Kit Distribution Through PrEP Clients' Social Networks.

BACKGROUND: HIV self-testing (HIVST) can increase the reach of HIV testing. Preexposure prophylaxis (PrEP) clients may be ideal distributors of HIVST kits and PrEP information within their social networks. This study uses the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework to evaluate the distribution of HIVST bundled with PrEP information ("Test-to-PrEP" kits) among egocentric friendship networks of PrEP users. METHODS: The study was conducted in Miami from November 2021 to March 2022. Enrolled PrEP clients (egos; n = 100) were offered Test-to-PrEP kits for distribution. Egos and Test-to-PrEP kit users completed brief online surveys. Descriptive statistics are reported for participants, their reported network members, and users of the Test-to-PrEP kits. Logistic and Poisson regression assessed the relationship between characteristics of egos, alters, and the distribution of Test-to-PrEP kits. RESULTS: The 100 enrolled egos reported a total of 414 alters. Participants received 293 Test-to-PrEP kits for distribution with 47 of the 100 participants distributing at least 1 kit. Of those who scanned the quick-response code and responded to the survey, 16.2% reported no previous HIV test and 38.5% reported no prior knowledge of PrEP; 32.5% reported interest in distributing Test-to-PrEP kits, 3 successfully distributed kits, and 2 initiated PrEP. CONCLUSIONS: An approach using PrEP clients' social networks can disseminate HIVST bundled with PrEP information to critical populations including individuals lacking knowledge of PrEP or who have never been tested for HIV. Future studies will assess whether this use of network effects can increase reach and efficiency of HIV testing and PrEP information distribution.

Addressing disparities in Pre-exposure Prophylaxis (PrEP) access: implementing a community-centered mobile PrEP program in South Florida.

BACKGROUND: Pre-exposure prophylaxis (PrEP) for HIV prevention is highly effective, but disparities in PrEP access remain considerable, particularly among Black and Latino men who have sex with men (MSM). To address this, the University of Miami Mobile PrEP Program was created, offering mobile HIV prevention/PrEP services in areas throughout South Florida where HIV incidence is high and PrEP access is geographically limited. Using a community-centered participatory approach, the program strategized and executed expansion into the Liberty City neighborhood of Miami. This study qualitatively assessed factors affecting Mobile PrEP implementation as perceived by community stakeholders, clients, and program staff. METHODS: Forty-one in-depth interviews were conducted with 21 Mobile PrEP clients, 10 key informants from local health organizations, and 10 program staff. Interview questions queried perceived organizational and positional barriers and facilitators to mobile clinic implementation. Service satisfaction, setting preferences, social factors, and likelihood of recommending Mobile PrEP were also assessed. A thematic content analysis was performed using the Consolidated Framework for Implementation Research (CFIR) taxonomy as the guiding constructs for the analysis. RESULTS: Participant statements indicated that providing no-cost services, convenient location, program-covered rideshares, individualized patient navigation, and a community-centric approach to patient care, which included staff members with shared lived experiences to increase positive interactions and renewed trust among poorly served communities, were facilitators of PrEP access and intervention uptake. The importance of program familiarization with the community before implementation, particularly for Black and African American communities, who may experience unique barriers to accessing sexual healthcare was strongly emphasized by participants. CONCLUSIONS: The Mobile PrEP intervention was found to be an acceptable and accessible mode of HIV/STI preventive care. The importance of pre-implementation community engagement and preparation is emphasized. Future research is needed to refine understanding of the intervention's components and evaluate implementation determinants in other highly impacted neighborhoods.

A Mediterranean-Style Diet Improves the Parameters for the Management and Prevention of Type 2 Diabetes Mellitus.

Background and Objectives: Type 2 diabetes mellitus (T2DM) is a chronic condition recognized as the inability to maintain glucose homeostasis, typically presenting with insulin resistance and systemic inflammation. With the prevalence of T2DM and major risk factors, such as prediabetes and obesity, increasing each year, the need to address risk factor reduction strategies is crucial. Materials and Methods: Twenty-two men and women, overweight-to-obese adults (BMI mean: 26.1-31.6) (age range mean: 44.6-51.8) with T2DM, indicators of prediabetes, or who were metabolically healthy, participated in Cal Poly's Nutrition and Exercise in Type 2 Diabetes (CPNET) study. There were no significant differences in terms of age, BMI, or sex distribution among the groups at the baseline. This study's protocol included following a Mediterranean-style diet, the daily consumption of a high-quality whey protein supplement, and physical activity recommendations for 16 weeks. Body composition data, via dual-energy X-ray absorptiometry (DXA), and fasting blood samples were collected at the baseline and following the intervention. Due to restrictions associated with the outbreak of the COVID-19 pandemic, only 13 of the 22 participants who started this study were able to return for the second data collection to complete this study following the 16-week intervention. Results: The prediabetic and T2DM groups exhibited reductions in their fasting plasma glucose (12.0 mg/dL reduction in the prediabetic group; 19.6 mg/dL reduction in the T2DM group) to that of normal and prediabetic levels, respectively, while the T2DM group also demonstrated improvement in their hemoglobin A1c (reduced from 6.8% to 6.0%) to prediabetic levels. Additionally, the metabolically healthy, overweight group exhibited significant improvements in adiposity, while the obese prediabetic and T2DM groups showed non-significant improvements in all the measured metrics of body composition. No significant changes were observed in the inflammatory biomarkers (p-values ranged from 0.395 to 0.877). Conclusions: Collectively, our results suggest that adherence to a well-balanced, nutritious diet and activity may improve the parameters of glycemic control and provide benefits to body composition that help to manage and prevent the development of T2DM. Our study was able to yield significant findings signifying that the effects of a Mediterranean-style diet are observed even for a more conservative sample size.

Iatrogenic air embolism: pathoanatomy, thromboinflammation, endotheliopathy, and therapies.

Iatrogenic vascular air embolism is a relatively infrequent event but is associated with significant morbidity and mortality. These emboli can arise in many clinical settings such as neurosurgery, cardiac surgery, and liver transplantation, but more recently, endoscopy, hemodialysis, thoracentesis, tissue biopsy, angiography, and central and peripheral venous access and removal have overtaken surgery and trauma as significant causes of vascular air embolism. The true incidence may be greater since many of these air emboli are asymptomatic and frequently go undiagnosed or unreported. Due to the rarity of vascular air embolism and because of the many manifestations, diagnoses can be difficult and require immediate therapeutic intervention. An iatrogenic air embolism can result in both venous and arterial emboli whose anatomic locations dictate the clinical course. Most clinically significant iatrogenic air emboli are caused by arterial obstruction of small vessels because the pulmonary gas exchange filters the more frequent, smaller volume bubbles that gain access to the venous circulation. However, there is a subset of patients with venous air emboli caused by larger volumes of air who present with more protean manifestations. There have been significant gains in the understanding of the interactions of fluid dynamics, hemostasis, and inflammation caused by air emboli due to in vitro and in vivo studies on flow dynamics of bubbles in small vessels. Intensive research regarding the thromboinflammatory changes at the level of the endothelium has been described recently. The obstruction of vessels by air emboli causes immediate pathoanatomic and immunologic and thromboinflammatory responses at the level of the endothelium. In this review, we describe those immunologic and thromboinflammatory responses at the level of the endothelium as well as evaluate traditional and novel forms of therapy for this rare and often unrecognized clinical condition.

Inheritance and inequality among nomads of South Siberia.

At the headwaters of the Yenisei River in Tuva and northern Mongolia, nomadic pastoralists move between camps in a seasonal rotation that facilitates their animals' access to high-quality grasses and shelter. The use and informal ownership of these camps depending on season helps illustrate evolutionary and ecological principles underlying variation in property relations. Given relatively stable patterns of precipitation and returns to capital improvement, families generally benefit from reusing the same camps year after year. We show that locations with higher economic defensibility and capital investment-winter camps and camps located in mountain/river valleys-are claimed and inherited more frequently than summer camps and camps located in open steppe. Camps are inherited patrilineally and matrilineally at a ratio of 2 : 1. Despite its practical importance, camp inheritance is not associated with livestock wealth today, which is better predicted by education and wealth outside the pastoral economy. The relationship between the livestock wealth of parents and their adult children is significantly positive, but relatively low compared to other pastoralists. The degree of inequality in livestock wealth, however, is very close to that of other pastoralists. This is understandable considering the durability and defensibility of animal wealth and economies of scale common across pastoralists. This article is part of the theme issue 'Evolutionary ecology of inequality'.

Line-field confocal optical coherence tomography of cutaneous vascular lesions: Morphological assessment and histopathological correlations.

BACKGROUND: Cutaneous vascular lesions (VLs) are benign or malignant processes involving blood and/or lymphatic vessels, usually readily diagnosed with dermoscopy. However, cases showing unclear clinical/dermoscopic findings may require further investigations. Line-field confocal optical coherence tomography (LC-OCT) is a new, non-invasive imaging technique displaying high resolution and deep penetration. The aim of this study was to describe the LC-OCT features of the most common benign and malignant VLs and to correlate them with histopathological substrates. METHODS: Clinical, dermoscopic, LC-OCT and histopathological images of VLs were retrospectively collected. Detailed LC-OCT description and histopathological correlations were produced for different types of VLs. RESULTS: The study included 71 VLs belonging to 50 caucasian patients [31 (62%) females; median age 56.8 (30-83) years] study lesions included 25 cherry haemangiomas, 15 angiokeratomas, 10 thrombosed haemangiomas, six pyogenic granulomas, five venous lakes, four targetoid haemosiderotic haemangiomas, four Kaposi's sarcomas and two extraungual glomus tumours. LC-OCT detected increased dermal vascularity, assuming different size and shape according to the particular type of VLs. LC-OCT criteria correlated well to established histopathologic findings. CONCLUSION: The results of our preliminary observations indicate that in vivo evaluation with LC-OCT may provide practical clues for the identification of the vascular nature of a lesion and its differential diagnosis.

Major adverse cardiac events and cardiovascular toxicity with PARP inhibitors-based therapy for solid tumors: a systematic review and safety meta-analysis.

BACKGROUND: Poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi) provided significant antitumor activity in various tumors, mainly carrying deleterious mutations of BRCA1/BRCA2 genes. Only few data are available regarding the cardiac and vascular safety profile of this drug class. We carried out a meta-analysis for assessing the incidence and relative risk (RR) of major adverse cardiovascular events (MACEs), hypertension, and thromboembolic events in patients with solid tumors treated with PARPi-based therapy. METHODS: Prospective studies were identified by searching the Medline/PubMed, Cochrane Library, and ASCO Meeting abstracts. Data extraction was conducted according to the Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) statement. Combined odds ratios (ORs), RRs, and 95% confidence intervals (CIs) were calculated using fixed- or random-effects methods, depending on studies heterogeneity. RevMan software for meta-analysis (v.5.2.3) was used to carry out statistical analyses. RESULTS: Thirty-two studies were selected for the final analysis. The incidence of PARPi-related MACEs of any and high grade was 5.0% and 0.9%, respectively, compared with 3.6% and 0.9% in the control arms, corresponding to a significant increased risk of MACEs of any grade (Peto OR 1.62; P = 0.0009) but not of high grade (P = 0.49). The incidence of hypertension of any grade and high grade was 17.5% and 6.0% with PARPi, respectively, compared with 12.6% and 4.4% in the controls. Treatment with PARPi significantly increased the risk of hypertension of any grade (random-effects, RR = 1.53; P = 0.03) but not of high grade (random-effects, RR = 1.47; P = 0.09) compared with controls. Finally, PARPi-based therapies significantly increased the risk of thromboembolic events of any grade (Peto OR = 1.49, P = 0.004) and not of high grade (Peto OR = 1.31; P = 0.13) compared with controls. CONCLUSIONS: PARPi-based therapy is associated with a significantly increased risk of MACEs, hypertension, and thromboembolic events of any grade compared with controls. The lack of a significant increased risk of high-grade events together with the absolute low incidence of these adverse events led not to consider routine cardiovascular monitoring as recommended in asymptomatic patients.

Analysis of sleep and symptoms related to OSAS in a group of paediatric patients with Down syndrome.

AIM: Good sleep is fundamental for development, particularly in children. Sleep can be fragmented by obstructive sleep apnoea syndrome (OSAS). Children with Down syndrome (DS) are more likely to have obstructive sleep apnoea, due to their craniofacial characteristics. The diagnosis can be made through the administration of specific questionnaires. The purpose of the study is to analyse the results obtained from the administration of a questionnaire for the screening of OSAS in the paediatric population with DS. MATERIALS: The questionnaire chosen is a questionnaire validated in Italian and administered to 139 parents of children with DS. This questionnaire investigates the diurnal and nocturnal symptoms related to OSAS and their frequency. CONCLUSION: This study wants to state the importance of the administration of questionnaires for the screening of OSAS in children with Down syndrome and the role of the dentist in the early diagnosis.

Linguistic validation of a questionnaire for the screening of OSAS in a paediatric population with Down Syndrome.

AIM: Obstructive sleep apnoea syndrome (OSAS) is a common clinical condition in which the throat narrows or collapses repeatedly during sleep, causing obstructive sleep apnoea events. This disorder is present in the paediatric population with a prevalence estimated between 1.2% and 5.8%. Down Syndrome (DS) is the most common chromosomal alteration associated with mental disability and characterised by other clinical manifestations, and its incidence is estimated at 1/800 births worldwide. Most of the craniofacial features typical of DS represent a risk factor for the development of OSAS. Routine screening has been recommended in some countries but it is still not a standard practice. The aim of this study is the Italian linguistic validation of a questionnaire for the diagnosis of OSAS in children with Down Syndrome. METHODS: After careful review of the existing scientific literature, a specific questionnaire was selected for the diagnosis of OSAS in children with DS. The questionnaire was then translated into Italian and administered to 111 parents of children with Down syndrome, for online completion. The last part of the questionnaire was dedicated to the comprehension of the questionnaire itself, with a specific focus on its clarity, accuracy and difficulty in completing it. CONCLUSION: The positive feedback registered in the comprehension part of the questionnaire, certified the good quality of the Italian translation and confirmed the questionnaire as a useful screening method to identify the comorbidity of OSAS and DS.

Towards a science of archaeoecology.

We propose defining a field of research called 'archaeoecology' that examines the past ~60 000 years of interactions between humans and ecosystems to better understand the human place within them. Archaeoecology explicitly integrates questions, data, and approaches from archaeology and ecology, and coalesces recent and future studies that demonstrate the usefulness of integrating archaeological, environmental, and ecological data for understanding the past. Defining a subfield of archaeoecology, much as the related fields of environmental archaeology and palaeoecology have emerged as distinct areas of research, provides a clear intellectual context for helping us to understand the trajectory of human-ecosystem interactions in the past, during the present, and into the future.

Incidental findings of the nose and paranasal sinuses in orthodontic patients in the age of development: a retrospective study on CBCTs.

AIM: Nowadays, the use of CBCT in orthodontics and paediatric dentistry is constantly increasing. Since it allows a precise 3D visualisation of the entire head, CBCT can be used to identify alterations and pathologies of the jaws, but also of the sinonasal complex. Despite that, literature lacks studies focusing on the sinonasal complex of healthy orthodontic paediatric patients. Therefore, the aim of this cross-sectional retrospective study is to analyse the prevalence of incidental findings and anatomic variations of the nose and paranasal sinuses in orthodontic patients in the age of development. METHODS: The 61 CBCTs that respected all inclusion criteria (patient's age under 15 years old and CBCT scans showing the entire sinonasal complex, data in DICOM format) were searched for: nasal septum deviation, Onodi cells, Haller cells, concha bullosa, sinus underdevelopment, sinus mucosal thickening, sinus cysts or polypoid formations. CBCTs were evaluated by two different orthodontists and their findings were then compared and statistically analysed. CONCLUSION: Considered the high prevalence of incidental findings, prescription of a CBCT to paediatric patiens seems crucial in order to to detect conditions that would require referral to a specialist.

Understanding the coevolution of mask wearing and epidemics: A network perspective.

Nonpharmaceutical interventions (NPIs) such as mask wearing can be effective in mitigating the spread of infectious diseases. Therefore, understanding the behavioral dynamics of NPIs is critical for characterizing the dynamics of disease spread. Nevertheless, standard infection models tend to focus only on disease states, overlooking the dynamics of "beneficial contagions," e.g., compliance with NPIs. In this work, we investigate the concurrent spread of disease and mask-wearing behavior over multiplex networks. Our proposed framework captures both the competing and complementary relationships between the dueling contagion processes. Further, the model accounts for various behavioral mechanisms that influence mask wearing, such as peer pressure and fear of infection. Our results reveal that under the coupled disease-behavior dynamics, the attack rate of a disease-as a function of transition probability-exhibits a critical transition. Specifically, as the transmission probability exceeds a critical threshold, the attack rate decreases abruptly due to sustained mask-wearing responses. We empirically explore the causes of the critical transition and demonstrate the robustness of the observed phenomena. Our results highlight that without proper enforcement of NPIs, reductions in the disease transmission probability via other interventions may not be sufficient to reduce the final epidemic size.

Circadian disruption of hippocampus in an early senescence male mouse model.

Age-related cognitive decline and disruptions in circadian rhythms are growing problems as the average human life span increases. Multiple strains of the senescence-accelerated mouse (SAM) show reduced life span, and the SAMP8 strain in particular has been well documented to show cognitive deficits in behavior as well as a bimodal pattern of circadian locomotor activity. However, little is known about circadian regulation within the hippocampus of these strains of mice. Here we test the hypothesis that in this early senescence model, disruption of the molecular circadian clock in SAMP8 animals drives disrupted behavior and physiology. We found normal rhythms in PER2 protein expression in the SCN of SAMP8 animals at 4 months, despite the presence of disrupted wheel-running activity rhythms at this age. Interestingly, a significant rhythm in PER2 expression was not observed in the hippocampus of SAMP8 animals, despite a significant 24-h rhythm in SAMR1 controls. We also examined time-restricted feeding as a potential strategy to rescue disrupted hippocampal plasticity. Time-restricted feeding increased long-term potentiation at Schaffer collateral-CA1 synapses in SAMP8 mice (compared to SAMR1 controls). Overall, we confirm disrupted circadian locomotor rhythms in this early senescence model (as early as 4 months) and discovered that this disruption is not due to arrhythmic PER2 levels in the SCN; however, other extra-SCN circadian oscillators (i.e., hippocampus) are likely impaired with accelerated aging.

The role of postoperative radiotherapy in eccrine porocarcinoma: a multidisciplinary systematic review.

OBJECTIVE: Eccrine porocarcinoma (EPC) is a malignant adnexal tumor accounting for about 0.005% of skin tumors. The standard treatment of EPC is the complete surgical excision of the primary lesion and of the clinically involved lymph nodes. There is limited evidence regarding the role of radiotherapy (RT) in managing EPC after surgery. Therefore, the aim of this multidisciplinary systematic review is to analyze the available evidence about postoperative RT in the curative treatment of EPC. MATERIALS AND METHODS: A systematic search strategy was launched trough the main scientific databases including PubMed, Scopus and Cochrane. An additional manual search and a chain citation were performed about potentially relevant papers. The key words used for the search included "eccrine porocarcinoma", "porocarcinoma", "radiotherapy", "radiation therapy", "adjuvant radiotherapy" and "postoperative radiotherapy". RESULTS: A total of 104 publications were identified and 14 papers were included in the final analysis. The only articles found on adjuvant RT in EPC were case reports published between 1996 and 2019. There was a slight female prevalence (57% female/43% male) with a mean age of 65 years (range 37-85). Head-and-neck region was the most frequently involved anatomical site followed by legs. CONCLUSIONS: Adjuvant radiotherapy after surgical removal of EPC could be considered in cases with positive or close margins and in cases with unfavorable histological features. In view of limited literature data and the rarity of EPC the best treatment sequence should always be discussed within the frame of a multidisciplinary setting. ADVANCES IN KNOWLEDGE: adjuvant radiotherapy after surgical removal of EPC could be considered in cases with positive or close margins and in cases with unfavorable histological features.
