Money, chores and emotional support: Kenyan and Zambian fathers' perceptions of male partner involvement in maternal and infant health within the context of HIV. CULTURE, HEALTH & SEXUALITY 2023:1-16. [PMID: 37694847 DOI: 10.1080/13691058.2023.2249078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Accepted: 08/10/2023] [Indexed: 09/12/2023]
Abstract
In sub-Saharan Africa, involving male partners in the prevention of mother-to-child transmission of HIV improves maternal and infant outcomes. Male involvement is typically conceptualised as male partners attending antenatal care, which is difficult for many men. Little is known about how men view their involvement in family health within the context of HIV, particularly outside of clinic attendance. Through interviews with 35 male partners of pregnant or postpartum women living with HIV in Kenya and Zambia, this study elicited perceptions of male involvement in maternal and infant health in families affected by HIV. Men supported the importance of clinic attendance but reported conflicts with the need to work and fulfil their role as the family's financial provider. Providing money for necessities was deemed more critical for their family's health than clinic attendance. Men's involvement was conveyed through various other supportive actions, including helping with household chores and providing emotional support (showing love and reducing women's stress). Future strategies to promote male partner involvement in the prevention of mother-to-child transmission of HIV and maternal and child health should build upon the actions men view as most meaningful to promote their family's health within their real-world life circumstances and cultural context, particularly their role as financial providers.

Abstract
BACKGROUND Angiosarcoma (AS) of the breast is very rare, accounting for 1% of all soft tissue breast tumors. AS may present as primary tumors of the breast or as secondary lesions usually associated with previous radiotherapy. Commonly, secondary AS affects older women (median age 67-71 years) with a clinical history of breast cancer. The preferred site of onset of RIAS is the edge of radiation fields, where radiation doses and tumor necrosis may be heterogeneous, resulting in a DNA damage and instability. Radical surgery is the treatment of choice, but no clear consensus exists on surgical management of breast AS. CASE REPORT We describe an atypical case of relapsed RIAS after radical mastectomy, treated with new surgery and, considering the higher risk of recurrence, subsequent adjuvant chemotherapy with weekly paclitaxel. CONCLUSIONS The frequency of radiation-induced angiosarcomas (RIAS) after breast-conserving surgery and radiotherapy has been increased to 0.14-0.5% among long survivors. Nevertheless, even if RIAS continues to be prognostically an extremely unfavorable cancer due to a high rate of recurrence, distant spread, and median overall survival (OS) of about 60 months, the benefits of loco-regional breast radiotherapy are clearly higher than the risk in developing angiosarcoma.

Abstract
In recent years, the advanced knowledge of clinical, biological and molecular features of prostate cancer have led to the introduction of new drugs and have allowed the relocation of old drugs in different settings. In this way, the new concepts of systemic disease arise: high risk or high volume vs. low risk and low volume disease castration sensitive prostate cancer (CSPC), diversifying the use of previously approved drugs (CRPC) and opening new scenarios for sequence therapy. The aim of this review is to integrate new developments into the medical management of systemic prostate cancer.

Abstract
Background Phthalates are known endocrine disruptors used in a wide range of industrial and household products. With globalization and interdependency of the supply chain, the control of toxic substances in daily use products has become more challenging. Many countries have implemented laws and policies to limit their use, although these regulations are neither unified nor seem adequate, as studies suggest that more vulnerable populations (children, pregnant women) are exposed to phthalates that should be restricted. Methods For seven of the most used phthalates - bis(2-Ethylhexyl) phthalate (DEHP), Butylbenzyl phthalate (BBP), Dibutyl phthalate (DBP), Diisobutyl phthalate (DIBP), diisononyl phthalate (DINP), diisodecyl phthalate (DIDP), Di-n-octyl phthalate (DNOP) - we performed an online research on institutional sites and dedicated Agencies of the three largest world economies (European Union (EU), United States of America (USA), China) to analyze their uses and bans, focusing on Food Contacts Materials (FCM), cosmetics, toys and childcare articles. Results In the EU area DEHP, BBP, DBP and DIBP are not allowed in toys and childcare articles above 0,1% by weight. All the seven phthalates are also severely restricted in FCM, and mostly banned as cosmetic components. In the USA, there is no formal prohibition to their use in cosmetics but phthalates are mostly limited in FCM. In China, the limit for DBP, BBP, DEHP, DNOP, DINP, DIDP in plastic toys is 0,1% of the material composition; regarding cosmetics DEHP, BBP and DBP are prohibited. Conclusions We found substantial differences in the international legislation. Though there is essential agreement on toys and childcare articles legislation, there are many discrepancies about FCM and cosmetics. Further research is needed to compare the regulation with data about concentrations of these ubiquitous elements, to underline the real exposure and risk in different populations and to improve knowledge and safety on this matter. Key messages • Phthalates, known endocrine disruptors, in daily use products are a matter of concern. • Coordinated international laws to prevent exposure, especially in vulnerable populations, are needed.

Abstract
Background Using explanatory mixed methods, we characterize the education that patients with breast cancer received about potential sexual health effects of treatment and explore preferences in format, content, and timing of education. Patients and Methods Adult patients with stage 0–IV breast cancer seen at an academic breast center during December 2020 were emailed questionnaires assessing sexual health symptoms experienced during treatment. Patients interested in further study involvement were invited to participate in semistructured interviews. These interviews explored sexual health education provided by the oncology team and patient preferences in content, format, and timing of education delivery. Results Eighty-seven (32%) patients completed the questionnaire. Most patients reported decreased sexual desire (69%), vaginal dryness (63%), and less energy for sexual activity (62%) during/after treatment. Sixteen patients participated in interviews. Few women reported receiving information about potential sexual effects of breast cancer treatment; patients who did reported a focus on menopausal symptoms or fertility rather than sexual function. Regarding preferences in format, patients were in favor of multiple options being offered rather than a one-size-fits-all approach, with particular emphasis on in-person options and support groups. Patients desired education early and often throughout breast cancer treatment, not only about sexual side effects but also on mitigation strategies, sexual function, dating and partner intimacy, and body image changes. Conclusion Few patients received information about the sexual health effects of breast cancer treatment, though many experienced symptoms. Potential adverse effects should be discussed early and addressed often throughout treatment, with attention to strategies to prevent and alleviate symptoms and improve overall sexual health.

Abstract
Introduction The Covid-19 pandemic and statewide stay-at-home orders abruptly impacted clinic operations necessitating the incorporation of telehealth. Uptake of telehealth is multifaceted. Clinician acceptance is critical for success. The aim of this study is to understand maternity care providers’ acceptance of and barriers to providing virtual maternity care. Methods Providers completed a baseline and 3-month follow up survey incorporating the validated implementation outcome measures, feasibility of intervention measure (FIM), intervention appropriateness measure (IAM), and acceptability of intervention measure (AIM).Statistical analyses evaluated differences between groups in this small convenience sample to understand trends in perceptions and barriers to telehealth. While not intended to be a qualitative study, a code tree was used to evaluate open-ended responses. Results Baseline response rate 50.4% (n = 56). Follow-up retention/response-rate 68% (n = 38). Most reported no prior telehealth experience. 94% agreed with the FIM, decreasing to 92% at follow-up. 80% (prenatal) and 84% (postpartum) agreed with the IAM. Agreement with the AIM increased to 83%.Differences in the FIM and AIM found by division (p < 0.01) and years in practice (p < 0.01). Identified barriers included patient lack of essential tools, inadequate clinic support, and patients prefer in person visits. Themes that emerged included barriers, needs, and areas of success. Discussion Telehealth was found to be feasible, appropriate, and acceptable across provider types and divisions. Improving patient/provider access to quality equipment is imperative. Future research must address how and when to incorporate telehealth.

Abstract
The diagnosis of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection relies on the detection of viral RNA by real-time reverse transcription polymerase chain reaction (rRT-PCR) performed with respiratory specimens, especially nasopharyngeal swabs. However, this procedure requires specialized medical personnel, centralized laboratory facilities, and time to provide results (from several hours up to 1 d). In addition, there is a non-negligible risk of viral transmission for the operator who performs the procedure. For these reasons, several studies have suggested the use of other body fluids, including saliva, for the detection of SARS-CoV-2. The use of saliva as a diagnostic specimen has numerous advantages: it is easily self-collected by the patient with almost no discomfort, it does not require specialized health care personnel for its management, and it reduces the risks for the operator. In the past few months, several scientific papers, media, and companies have announced the development of new salivary tests to detect SARS-CoV-2 infection. Posterior oropharyngeal saliva should be distinguished from oral saliva, since the former is a part of respiratory secretions, while the latter is produced by the salivary glands, which are outside the respiratory tract. Saliva can be analyzed through standard (rRT-PCR) or rapid molecular biology tests (direct rRT-PCR without extraction), although, in a hospital setting, these procedures may be performed only in addition to nasopharyngeal swabs to minimize the incidence of false-negative results. Conversely, the promising role of saliva in the diagnosis of SARS-CoV-2 infection is highlighted by the emergence of point-of-care technologies and, most important, point-of-need devices. Indeed, these devices can be directly used in workplaces, airports, schools, cinemas, and shopping centers. An example is the recently described Rapid Salivary Test, an antigen test based on the lateral flow assay, which detects the presence of the virus by identifying the spike protein in the saliva within a few minutes.

Abstract
An important requirement for a state-of-the-art hepatitis B surface antigen (HBsAg) screening assay is reliable detection of mutated HBsAg. Currently, there is a striking shortage of data regarding the detection rates of in vivo HBsAg mutations for these clinically important assays. Therefore, we compared the detection rates of four commercial HBsAg screening assays using a global cohort of 1553 patients from four continents with known HBV genotypes. These samples, which represent the broadest spectrum of known and novel HBsAg major hydrophilic region (MHR) mutations to date, were analyzed for the presence of HBsAg using the Roche Elecsys® HBsAg II Qualitative, Siemens ADVIA Centaur XP HBsAg II, Abbott Architect HBsAg Qualitative II and DiaSorin Liaison® HBsAg Qualitative assays, respectively. Of the 1553 samples, 1391 samples could be sequenced; of these, 1013 (72.8%) carried at least one of the 345 currently known amino acid substitutions (distinct HBsAg mutation) in the HBsAg MHR. All 1553 patient samples were positive for HBsAg using the Elecsys® HBsAg II Qual assay, with a sensitivity (95% confidence interval) of 99.94% (99.64%-100%), followed by the Abbott Architect 99.81% (99.44%-99.96%), Siemens ADVIA 99.81% (99.44%-99.96%) and DiaSorin Liaison® 99.36% (98.82%-99.69%) assays, respectively. Our results indicate that the Elecsys® HBsAg II Qual assay exhibits the highest sensitivity among the commercial HBsAg screening assays, and demonstrate that its capacity to detect HBV infection is not compromised by HBsAg MHR mutants.

Abstract
BACKGROUND Therapy of chronic hepatitis D with Interferon is successful when testing for HDV-RNA turns negative. This end-point is disputed. AIM To assess the role of serum hepatitis B surface antigen (HBsAg) in the clearance of HDV-RNA in pegylated interferon (Peg-IFN)-treated chronic hepatitis D (CHD). METHODS Sixty-two patients with CHD, treated with Peg-IFN, were considered. The patients belonged to three groups: 14 patients cleared the HBsAg and HDV-RNA (responders, R), 12 cleared the HDV-RNA remaining positive for HBsAg (partial responders, PR) and 36 cleared neither the HBsAg nor the HDV-RNA (nonresponders, NR). RESULTS In responders, at baseline the median value (mv) of HBsAg and HDV-RNA was 1187 and 188 663 IU/mL. By month 6 of therapy, HBsAg declined to less than 1000 IU/mL and HDV-RNA was undetectable in 12 patients. In NR, the pre-therapy median value of HBsAg and HDV viremia was 6577 and 676 319 IU/mL. There was no significant reduction of antigen at month 6; after a decline, HDV-RNA rebounded to baseline levels. In PR, the median value of baseline HBsAg was 7031 IU/mL; it declined at month 6 in the majority. HDV-RNA progressively declined from an initial median value of 171 405 IU/mL. HBsAg <1000 IU/mL at month 6 discriminated responders and PR from NR (P < 0.001). By ROC curve, the threshold of 0.105 log reduction of HBsAg associated with 1.610 log reduction of HDV-RNA from baseline to month 6 predicted the clearance of this marker. CONCLUSIONS A reduction of serum HBsAg is mandatory for the definitive clearance of the HDV-RNA. Quantitative HBsAg may predict the long-term response to Peg-IFN therapy and provide a guide to prolong or stop treatment.

Abstract
Human serum albumin (HSA): (i) controls the plasma oncotic pressure, (ii) modulates fluid distribution between the body compartments, (iii) represents the depot and carrier of endogenous and exogenous compounds, (iv) increases the apparent solubility and lifetime of hydrophobic compounds, (v) affects pharmacokinetics of many drugs, (vi) inactivates toxic compounds, (vii) induces chemical modifications of some ligands, (viii) displays antioxidant properties, and (ix) shows enzymatic properties. Under physiological and pathological conditions, HSA has a pivotal role in heme scavenging transferring the metal-macrocycle from high- and low-density lipoproteins to hemopexin, thus acquiring globin-like reactivity. Here, the heme-based catalytic properties of HSA are reviewed and the structural bases of drug-dependent allosteric regulation are highlighted.

Abstract
AIM To evaluate similarities and differences in HCV-1 subtypes 1a and 1b in the presenting clinical features and the response to peg-interferon and ribavirin (Peg/RIBA). PATIENTS AND METHODS A total of 1,233 naïve patients with HCV genotype-1 infection, 159 (13%) with subtype 1a and 1,074 (87%) with subtype 1b were treated with Peg-IFN/RIBA at 12 Italian centers. Covariates included in the logistic model were age, gender, BMI, serum alanine aminotransferase, serum gamma-glutamiltranspeptidase (γGT), platelets counts, liver fibrosis, the occurrence of type 2 diabetes, baseline viremia, and IL28B genotype. RESULTS At multivariate analysis, baseline characteristics differentiating patients with HCV-1a versus HCV-1b were young age, male gender, no F4 fibrosis, and no diabetes. SVR was achieved by 37% of patients with subtype 1b and 45% of those with subtype 1a, a nonsignificant difference of 8% (p = 0.069). In patients with subtype 1a, predictors of SVR were IL28B CC (OR 5.78, CI 1.98-16.83), RVR (OR 4.18, CI 1.66-10.55), female gender (OR 2.83, CI 1.83-6.78), and HCVRNA (OR 0.55, CI 0.32-0.96). In patients with subtype 1b, the ranking of predictors was levels RVR (OR 6.49, CI 4.32-9.73), IL28B CC (OR 3.32, CI 2.15-4.58), γGT (OR 1.59, CI 0.14-2.22), HCVRNA (OR 0.61, CI 0.47-0.79), and age (OR 0.01, CI 0.02-0.42). CONCLUSION In Italy HCV-1 subtype 1a prevails in young male patients with less advanced liver damage, findings that imply a more recent spreading of the infection with this viral strain. The two HCV-1 subtypes appear equally responsive to Peg-IFN/RIBA, with IL28B genotyping and monitoring of RVR mostly influencing the therapeutic response.

Abstract
BACKGROUND The continuing migration of individuals from geographic areas with high/medium endemicity has determined the arrival of new chronic hepatitis B virus (HBV) carriers in Italy. The magnitude of this phenomenon and clinical/virological features of HBsAg-positive migrants remain not very well defined. AIMS To evaluate the proportion of HBsAg-positive immigrants enrolled in this multicenter Società Italiana di Malattie Infettive e Tropicali (SIMIT) cross-sectional study and to compare the characteristics of chronic hepatitis B infection in migrants to those of Italian carriers. METHODS From February 1 to July 31 2008, anonymous data were obtained from all HBsAg-positive patients aged ≥ 18 years observed at 74 Italian centers of infectious diseases. RESULTS Of the 3,760 HBsAg-positive subjects enrolled, 932 (24.8 %) were immigrants, with a prevalent distribution in central to northern Italy. The areas of origin were: Far East (37.1 %), Eastern Europe (35.4 %), Sub-Saharan Africa (17.5 %), North Africa (5.5 %), and 4.5 % from various other sites. Compared to Italian carriers, migrants were significantly younger (median age 34 vs. 52 years), predominantly female (57.5 vs. 31 %), and most often at first observation (incident cases 34.2 vs. 13.3 %). HBeAg-positives were more frequent among migrants (27.5 vs. 14 %). Genotype D, found in 87.8 % of Italian carriers, was present in only 40 % of migrants, who were more frequently inactive HBV carriers, with a lower prevalence of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Only 27.1 % of migrants received antiviral treatment compared to 50.3 % of Italians. CONCLUSIONS Twenty-five percent of all HBV carriers examined at Italian centers was composed of immigrants with demographic, serological, and virological characteristics that differed from those of natives and appeared to have an inferior access to treatment.

Abstract
BACKGROUND Sorafenib is a small-molecule multitargeted kinase inhibitor that blocks the activation of C-RAF, B-RAF, c-KIT, FLT-3, RET, vascular endothelial growth factor receptor 2 (VEGFR-2), VEGFR-3 and platelet-derived growth factor receptor β. The aim of this multicenter, randomized phase II study was to evaluate clinical activity and safety of sorafenib in combination with erlotinib or gemcitabine in unselected untreated elderly patients with non-small-cell lung cancer (NSCLC). METHODS The trial was designed to select the most promising sorafenib-containing combination in previously untreated elderly (≥70 years) stage IIIB or IV NSCLC patients, with performance status of zero to two. Patients were randomly assigned to one of the following combinations: gemcitabine, 1200 mg/m(2) days 1 and 8, every 21 days, for a maximum of six cycles, plus sorafenib, 800 mg/day, until disease progression or unacceptable toxicity (arm 1); or erlotinib, 150 mg/day, plus sorafenib, 800 mg/day, until disease progression or unacceptable toxicity (arm 2). A selection design was applied with 1-year survival rate as the primary end point of the study, requiring 58 patients. RESULTS Sixty patients were randomly allocated to the study (31 patients in arm 1 and 29 patients in arm 2). After a median follow-up of 15 months, 10 patients [32%, 95% confidence interval (CI) 16% to 49%] in arm 1 and 13 patients (45%, 95% CI 27% to 63%) in arm 2 were alive at 1 year. Median overall survival was 6.6 and 12.6 months in arm 1 and arm 2, respectively. Observed toxic effects were consistent with the expected drug profiles. CONCLUSIONS The combination of erlotinib and sorafenib was feasible in elderly patients with advanced NSCLC and was associated with a higher 1-year survival rate than the other arm. According to the selection design, this combination warrants further investigation in phase III trials.

Abstract
Lymphoepithelial carcinoma is an undifferentiated nasopharyngeal carcinoma with lymphoid stroma and non-keratinizing squamous cells with distinctive clinical, epidemiological and etiological features. Conversely, lymphoepithelioma-like carcinomas (LELCs) are carcinomas that arise outside the nasopharynx but resemble a lymphoepithelioma histologically. In this case study, LELC presentation in connective tissue (left sternocleidomastoid muscle) is peculiar and unusual, but its diagnosis is supported by histological findings and clinical history, especially long disease free survival and no primary lesions in nasopharynx and lung district. We also discuss the pathogenesis, hypothesizing an embryological theory. To our knowledge, it could be the first reported case of a primary connective tissue LELC to the neck.

Abstract
In the Milan area (Northern Italy), we identified a family characterized by a high prevalence of ovarian and breast cancer cases (5 out of 6 subjects, over 3 generations), and a predominant prevalence of ovarian lesions (4 out of 5 patients). Analysis of BRCA1 and BRCA2 genes allowed the identification of the missense c.190T>C mutation in codon 64 (Cys64Arg) of BRCA1. The aims of the present investigation were to characterize the functional implications of the c.190T>C mutation at the molecular level, and to search whether additional polymorphisms might be linked to the peculiar phenotypic features observed in the Italian pedigree. Molecular modelling studies suggested that substitution of the cysteine 64 with an arginine likely disrupts the architecture of the BRCA1 RING finger domain, responsible for the interaction with BARD1, essential for the tumor-suppressor activity of the BRCA1-BARD1 complex. By splicing site information analysis, exonic splicing enhancer site characterization, and analysis of transcript fragment length and sequence, we showed that the c.190T>C mutation was able to modulate the splicing of exon 5 in a fashion opposite to the c.190T>G transversion, responsible for the functionally-related Cys64Gly amino acid substitution. Genotyping of BRCA1 and BRCA2 in the Italian family revealed the presence of two significant polymorphisms: the cancer-associated c.2612C>T SNP in BRCA1, and the c.-26G>A SNP in the BRCA2 gene, acting as an ovarian cancer risk modifier in carriers of deleterious BRCA1 mutations. Analysis of these SNPs in a genotypically-unrelated Polish family, characterized by prevalent breast neoplasms in carriers of the c.190T>C mutation, revealed a genetic profile consistent with the hypothetic role of both polymorphisms.

Abstract
Historically, radiotherapy has been occasionally used in the treatment of gastric cancer. More recently, the results of INT-0116 trial have shown an improvement of disease-free and overall survival by chemoradiation with a significant impact on the management of this tumor. Based on these data, there has been an increasing interest in radiotherapy and its association with chemotherapy for patients with locoregional disease as a part of an adjuvant treatment after surgery in high-risk patients. However, many questions remain to evaluate; first of all the toxicity of this approach and its efficacy after adequate surgery.

Abstract
Human mesencephalic neuromelanin (NM) is characterized by an irregular, undefined structure, making its characterization by usual physico-chemical methodologies quite difficult. NM isolated from controls and from Parkinson's Disease (PD) patients was compared by high-resolution solid-state nuclear magnetic resonance (NMR). The pigment from PD patients appeared to be mainly composed of highly cross-linked, protease-resistant lipo-proteic material, with disappearance of melanin NMR resonances, suggesting melanin breakout due to oxidative stress conditions. Moreover, alpha-synuclein was detected in NM of PD patients and controls after cleavage of the melanin backbone under solubilizing conditions. NM stores iron ions as oxyhydroxide iron clusters containing thousands of iron atoms. Electron Paramagnetic Resonance (EPR) investigations and magnetic susceptibility measurements confirmed the occurrence of magnetic coupling among iron atoms, whereas in synthetic melanin the occurrence of isolated Fe(3+) ions was evident. NM from PD patients showed a lower total magnetization, possibly suggesting a progressive Fe migration from its storage environment (i.e., NM) to the cytosol.
