Cáncer de mama en el hombre. Reporte de caso / Breast cancer in men. Case repor

Introducción: El cáncer de mama masculino es una patología infrecuente que re-presenta menos del 1% de la patología mamaria maligna, con una edad media de diagnóstico de 67 años. Tiene un peor pronóstico que el cáncer de mama femenino debido a su alto origen genético y baja sospecha, desencadenando diagnósticos inadecuados y tardíos, y disminuyendo la supervivencia a mediano y largo plazo.Objetivo: Describir el caso clínico de un paciente masculino con diagnóstico de cáncer de mama, abordando la presentación clínica, los métodos diagnósticos, el tratamiento oncoespecífico, y la evolución clínica y quirúrgica. Presentación del caso: Se presenta un paciente masculino de 52 años, con evi-dencia de lesión exofítica en mama derecha más ganglio axilar ipsilateral, con diag-nóstico confirmado de patología de cáncer de mama estadio clínico cT4bN1Mx. Se plantea un manejo multidisciplinario: quimioterapia neoadyuvante y mastecto-mía radical derecha. Finalmente recibe tratamiento oncoespecífico y radioterapia con evolución favorable.Discusión: El cáncer de mama masculino tiene una baja incidencia respecto a la mujer, por lo que su sospecha diagnóstica se ve limitada. En etapas iniciales el diagnóstico es inespecífico debido a las pocas manifestaciones clínicas, pero deberá respaldarse en métodos imagenológicos, análisis anatomopatológico e in-munohistoquímico para guiar el tratamiento oncoespecífico.Conclusión: El cáncer de mama masculino posee una sospecha diagnóstica limi-tada que requiere un manejo multidisciplinario específico. La correcta estadifica-ción de la patología depende del seguimiento clínico y un análisis inmunohistoquí-mico oportuno, para un tratamiento adecuado con mejores resultados clínicos y altas tasas de supervivencia.

Introduction: Male breast cancer is an infrequent pathology; it represents less than 1% of malignant breast pathology, with an average age of diagnosis of 67 years. It has a worse prognosis than female breast cancer, due to its high genetic origin and low suspicion, which leads to inadequate and late diagnosis, becoming evident in advanced stages, decreasing survival in the medium and long term.Objective: To describe the clinical case of a patient diagnosed with breast cancer, addressing the clinical presentation, diagnostic methods, oncospecific treatment, as well as the corresponding clinical and surgical evolution.Case presentation: We present a 52-year-old male patient, with evidence of exophytic lesion in right breast plus ipsilateral axillary node, with diagnosis confir-med by pathology report of breast cancer, clinical stage: cT4bN1Mx. A multidisci-plinary management is proposed, initially the patient receives neoadjuvant chemo-therapy, then undergoes a surgical procedure: radical right mastectomy. Finally, she receives oncospecific treatment in the specialties of clinical oncology and radiothe-rapy, with favorable evolution.Discussion: Male breast cancer has a low incidence compared to women, so its diagnostic suspicion is limited. In initial stages the diagnosis is unspecific due to the few clinical manifestations, but should be supported by imaging methods and confirmatory methods, an anatomopathological and immunohistochemical analy-sis, to guide oncospecific treatment. Conclusions: Male breast cancer, is an infrequent pathology with limited diagnos-tic suspicion, which requires specific multidisciplinary management. It is important to have a continuous medical follow-up of the patient, to achieve at the time of diagnosis a correct clinical and immunohistochemical staging, which allows to fo-cus on the appropriate management and treatment, with better clinical outcomes and better survival rates.

El laboratorio de fertilidad masculina, su evolución en los últimos 20 años / The male fertility laboratory, its evolution over the last 20 years / O laboratório de fertilidade masculina, sua evolução ao longo dos últimos 20 anos

Resumen La mayor accesibilidad a los tratamientos de reproducción asistida (RA) y los avances de la criobiología produjeron cambios en los laboratorios de andrología. El objetivo de este trabajo fue analizar la demanda y evolución de las variables seminales en las últimas dos décadas, caracterizar el laboratorio andrológico actual, evaluar el impacto de la incorporación del aseguramiento de la calidad y la inclusión de los sistemas computarizados (CASA). Se utilizaron datos de las medias mensuales del control de calidad interno (n=22 528) y encuestas a profesionales de laboratorios andrológicos (n=65) y a médicos especialistas en fertilidad (n=33). La demanda global se redujo significativamente con el aumento de las solicitudes de primera vez. El volumen y recuento, variables dependientes de andrógenos, disminuyeron con los años. El criterio estricto en morfología disminuyó el porcentaje de normales; la mitad de los médicos encuestados recibieron resultados entre 0 y 10% y el 40% consideró que ponía en riesgo el valor clínico de la variable. El sistema CASA permitió objetivar la cinética espermática e incrementar el porcentaje de progresivos rápidos, pero pocos laboratorios lo incorporaron. El 66% de los médicos resuelven el factor andrológico severo por tratamientos clínicos y el 95% utiliza técnicas de RA. El análisis de semen es ejecutado fundamentalmente por bioquímicos especializados, con baja adhesión a la automatización y acreditación del laboratorio, pero con participación en programas de evaluación externa de calidad. La demanda disminuyó como consecuencia del aumento del tratamiento por RA. La reducción del porcentaje de formas normales compromete su utilidad clínica.

Abstract Increasing availability to assisted reproduction (AR) treatments in Argentina and advances in cryobiology resulted in changes in andrology laboratories. The aim of this study was to evaluate the demand and evolution of seminal variables in the last two decades, characterise the current andrology laboratory, evaluate the impact of the incorporation of quality assurance and the introduction of computer assisted semen analysis (CASA). Data were taken from internal quality control (IQC) monthly means (n=22 528) and professionals in charge of laboratories (n=65) and fertility physicians' (n=33) surveys. Overall demand decreased significantly while first-time orders increased. Sperm volume and sperm count -androgen dependent parameters- decreased over the years. Strict morphology criteria reduced the percentage of normal results; half of the physicians received results between 0 and 10% and 40% considered that it compromised the clinical value of the variable. The CASA system made it possible to objectify sperm kinetic, increasing the percentage of fast progressives, but few laboratories have incorporated it. Sixty-six percent of physicians resolve severe andrological factor by clinical treatments and 95% use AR techniques in those cases. Semen analysis is mainly performed by specialised biochemists, with low adherence to laboratory automatisation and accreditation, but with participation in external quality assessment programmes. The demand decreased because of the increase in AR treatment. The lower percentage of normal forms compromises their clinical utility.

Cáncer de mama en coraza en hombre: un caso poco frecuente

El cáncer de mama en coraza constituye una de las formas clínicas de presentación de las metástasis cutáneas del cáncer mamario. Es de aparición poco frecuente, sobre todo, en el sexo masculino. Se presenta el caso de un paciente de sexo masculino, de 74 años de edad, de color de piel negra, con antecedente de diabetes e hipertensión arterial que acudió a consulta de mastología provincial por presentar desde hacía algunos meses dolor discreto y unas lesiones pruriginosas en la mama derecha. Además de otros exámenes se le realizó biopsia escisional de pequeño fragmento de la lesión con estudio por parafina que informó metástasis cutánea de un carcinoma mamario en coraza según su forma de presentación clínica. Se muestra el caso porque no se localizó ninguna publicación en la provincia Cienfuegos ni en el país de un caso en el sexo masculino, por lo cual se considera de interés para el personal médico la publicación de este reporte.

Shell breast cancer is one of the clinical forms of presentation of cutaneous metastases of breast cancer. It is rare, especially in males. The case of a 74-year-old male patient with black skin color, with a history of diabetes and high blood pressure, who attended a provincial mastology consultation for a few months of mild pain and pruritic lesions on his neck, is presented the right breast. In addition to other examinations, an excisional biopsy of a small fragment of the lesion was performed with a paraffin study, which reported cutaneous metastasis of a shell breast carcinoma according to its clinical presentation. The case is shown because no publication was found in the province of Cienfuegos or in the country of a male case, which is why the publication of this report is considered of interest to medical personnel.

The essential role of adenine nucleotide translocase 4 on male reproductive function in mice

Adenine nucleotide translocator 4 (Ant4), an ATP/ADP transporter expressed in the early phases of spermatogenesis, plays a crucial role in male fertility. While Ant4 loss causes early arrest of meiosis and increased apoptosis of spermatogenic cells in male mice, its other potential functions in male fertility remain unexplored. Here, we utilized Ant4 knockout mice to delineate the effects of Ant4-deficiency on male reproduction. Our observations demonstrated that Ant4-deficiency led to infertility and impaired testicular development, which was further investigated by evaluating testicular oxidative stress, autophagy, and inflammation. Specifically, the loss of Ant4 led to an imbalance of oxidation and antioxidants. Significant ultrastructural alterations were identified in the testicular tissues of Ant4-deficient mice, including swelling of mitochondria, loss of cristae, and accumulation of autophagosomes. Our results also showed that autophagic flux and AKT-AMPK-mTOR signaling pathway were affected in Ant4-deficient mice. Moreover, Ant4 loss increased the expression of pro-inflammatory factors. Overall, our findings underscored the importance of Ant4 in regulating oxidative stress, autophagy, and inflammation in testicular tissues. Taken together, these insights provided a nuanced understanding of the significance of Ant4 in testicular development.

Characteristics of resting energy expenditure and evaluation of prediction formulas in young men with different body mass indexes / 北京大学学报(医学版)

Objective:To compare the resting energy expenditure(REE)characteristics among young men with different body mass indexes(BMI).Methods:Thirty young men[average age was(26.93± 4.16)years]were enrolled in this study.They underwent resting metabolism tests in the Department of Sports Medicine of Peking University Third Hospital from December 2017 to June 2021.The resting meta-bolic rate(RMR)was measured by indirect calorimetry,the body composition was measured by bioresis-tance antibody component analyzer.The REE characteristics were analyzed,and 11 predictive equations were used to estimate RMR and compared with the measured value.The differences were analyzed by paired t-test and intra-class correlation coefficient(ICC).Results:The RMR of the overall 30 young men was(1 960.17±463.11)kcal/d(1 kcal=4.186 8 kJ).Including(1 744.33±249.62)kcal/d in those with normal BMI,which was significantly lower than that in those who were overweight or obese[(2 104.06±520.32)kcal/d,P＜0.01],but the weight-corrected RMR in those with normal BMI was significantly higher than that in those who were overweight or obese[(24.02±2.61)kcal/(kg·d)vs.(19.98±4.38)kcal/(kg·d),P＜0.01].The RMR was significantly and positively correlated with body weight,adiposity,lean body mass,body surface area,and extracellular fluid in the subjects with diffe-rent BMI(all P＜0.05).The predicted values of the 11 prediction equations were not in good agreement with the measured values(all ICC＜0.75),with relatively high agreement between the pre-dicted and measured values of the World Health Organization(WHO)equation in overweight obese young men(ICC=0.547,P＜0.01).Conclusion:There were significant differences in RMR among young men with different BMI,and the RMR after weight correction should be considered for those who were overweight or obese.The consistency between the predicted values of different prediction equations and the actual measured values of RMR was relatively poor,and it is recommended to accurately measure RMR by indirect calorimetry.For overweight or obese young men,the WHO prediction equation can be considered to calculate RMR,but it is necessary to establish an RMR prediction equation applicable to different BMI populations.

Association of agression and angry expression category perception under social exclusion among male students in reform school / 中国学校卫生

Objective@#To explore the relationship between aggression and category perception of angry expression in reform school students under social exclusion, so as to provide reference for the reform school students mental health promotion.@*Methods@#In May 2023, 144 students were randomly selected from a reform school in Guizhou Province, and were divided into high and low aggression groups(77 and 67 students) by Aggression Questionnaire. Cyberball game was used to induce social exclusion and acceptance, subjects were divided into high aggressive exclusion group ( n =42), high aggressive acceptance group ( n =35), low aggressive exclusion group ( n =37) and low aggressive acceptance group ( n =30). All the participants completed the discrimination and identification tasks of category perception paradigm, and the relationship between aggression and category perception of angry expression of reform school students under social exclusion was analyzed by using category turning point, identification curve and analysis of variance.@*Results@#The total score of aggression(97.34±8.00) and four dimensions (physical aggression: 29.75± 4.61, verbal aggression:17.19±2.58, anger:22.29±3.66, hostility:28.10±3.54) in the high aggression group were higher than those in the low aggression group(74.10±9.02，21.09±4.98，14.30±2.66，17.16±3.83，21.55±3.88), and the differences were statistically significant ( t =16.38, 10.85, 6.62, 8.20, 10.59, P <0.01). For identifying the turning point of the fear anger continuum, the social exclusion group（2.58±0.07）was significantly smaller than the social acceptance group（2.79±0.07）( F =4.85, η 2=0.07, P < 0.05 ）, and the social exclusion group had a tendency to shift the category boundary to the fear side. For identifying the slope at the angry happiness continuum category boundary curve, the high aggression group (0.63±0.03) was significantly higher than the low aggression group (0.53±0.03)( F =5.38, η 2=0.08, P <0.05). In the fear anger continuum,the high aggression group[(694.86± 78.29 )ms] reacted more quickly than the low aggression group[(660.70±79.86)ms]( F =5.08, η 2=0.05， P <0.05) In the angry happiness continuum, there was no statistical significance of social exclusion and aggression( P >0.05).@*Conclusions@#The suggests that social exclusion can lead to hostility attribution bias in individuals, while aggression can make individuals more sensitive to angry expression. The mechanisms by which social exclusion and aggression affect expression category perception are independent rather than interactive. The society should give tolerance and acceptance to reform school students, reduce exclusion and discrimination, and the reform education department should correct the aggressive behavior of reform school students and promote their mental health.

Efficacy of aripiprazole combined with olanzapine for hospitalized male patients with schizophrenia and its effect on metabolic syndrome / 四川精神卫生

BackgroundSchizophrenia and the use of antipsychotic medications are identified to be the likely contributors to the development of metabolic syndrome （MS） and cardiovascular disease， and jeopardize the prognosis of schizophrenia. Therefore， effectively preventing or reducing the risk of developing MS in patients with schizophrenia is critical. ObjectiveTo explore the efficacy of aripiprazole combined with olanzapine for male schizophrenia patients and its effect on MS， so as to provide a certain reference for the selection of antipsychotic drugs for schizophrenia patients. MethodsMale patients （n=80） who were hospitalized in The Third People's Hospital of Meizhou from February to June 2023 and fulfilling the International Classification of Diseases， tenth edition （ICD-10） diagnostic criteria for the schizophrenia were enrolled， and grouped using random number table method， each with 40 cases. Study group was treated with aripiprazole combined with olanzapine， while control group was given aripiprazole monotherapy. The treatment lasted for 6 continuous weeks in both groups. At the baseline， Positive and Negative Symptom Scale （PANSS） score， MS-related indices ［fasting plasma glucose （FPG）， hemoglobin A1c （HbA1c）， body mass index （BMI）， waist-to-hip ratio （WHR）， lipid profile］， S100 calcium-binding protein B （S100B） and high sensitivity C-reactive protein （hs-CRP） were recorded. Then the PANSS scores at the end of the 2nd， 4th and 6th week of treatment， the Clinical Global Impression （CGI） scores at the end of the 2nd and 6th week of treatment， as well as the MS-related indices， S100B， hs-CRP， Treatment Emergent Symptom Scale （TESS） score and Rating Scale for Extrapyramidal Side Effects （RSESE） score at the end of the 6th week of treatment were recorded in all participants. ResultsAnalysis on PANSS score revealed a significant group effect， time effect and group×time interaction effect （F=18.092， 634.780， 2.917， P<0.05 or 0.01）. Analysis on CGI score revealed a significant group effect and time effect （F=20.492， 99.190， P<0.01）. At the end of the 6th week of treatment， study group detected lower serum concentrations of HbA1c and triglyceride （TG） compared with control group （t=-3.495， -3.293， P<0.05）. The post-treatment hs-CRP level was lower in study group than that in control group （t=-3.916， P<0.05）. Study group scored lower on TESS compared with control group （t=-4.684， P<0.01）. ConclusionAripiprazole combined with olanzapine can effectively alleviate psychotic states in male schizophrenia patients， and the combination therapy yields less impact on MS-related indices than olanzapine monotherapy. ［Funded by Meizhou Science and Technology Plan Project （number， 2022B116）］

The penile vibrating perception threshold assay can help diagnose the severity of erectile dysfunction / 现代泌尿外科杂志

【Objective】 To analyze the application value of penile vibrating perception threshold measurement in the diagnosis of erectile dysfunction (ED) and provide reference for the seversity of ED patients. 【Methods】 The clinical data, Erectile Hardness Scale (EHS) score, International Index of Erectile Function Questionnaire-5 (IIEF-5) score, and the vibrating perception threshold (VPT) of the penis of 257 patients with decreased erectile function as the main complaint or accompanying symptoms treated during Jan. and Dec.2021 were retrospectively collected and analyzed.Patients with EHS=4 and IIEF-5≥22 were classified into the normal group, and the rest into the ED group.The differences in VPT in patients with different EHS scores were compared, and the correlation between IIEF-5 and VPT was analyzed.The diagnostic value of VPT for ED was evaluated with receiver operating characteristic (ROC) curve. 【Results】 The difference in penile VPT among patients with different EHS scores was statistically significant (P<0.05).With the decrease of EHS score, VPT showed an increasing trend.Glans VPT was negatively correlated with IIEF-5 score (ρ=-0.22, P<0.001), and penile shaft VPT was also negatively correlated with IIEF-5 score (ρ=-0.26, P<0.001).The VPT of glans penis [(4.17±1.37) V vs.(3.47±1.24) V, P=0.009] and the VPT of penis body [(3.73±1.41) V vs.(2.99±1.14)V, P=0.003] in the ED group were both higher than those in the normal group.The area under the ROC curve (AUC) of the glans VPT was 0.642.When the cut-off value was 3.537 V, the sensitivity was 63.4%, and the specificity was 63.6%.The AUC of the penile shaft VPT was 0.659.When the cut-off value was 2.775 V, the sensitivity was 72.3%, with a specificity of 54.5%. 【Conclusion】 The penile VPT of ED patients is higher than that of normal ones, and there is a correlation between VPT and the severity of ED.Severe ED is associated with higher VPT.The measurement of penile VPT is helpful for the clinical diagnosis of ED patients.

Introducción: Un bocio se considera intratorácico cuando más de un 50 por ciento de la glándula tiroides está en el mediastino, o sea, por debajo del nivel del estrecho torácico superior. Se trata de una enfermedad poco frecuente que padece aproximadamente el 3 por ciento de los pobladores del mundo. La incidencia del bocio nodular ha disminuido debido a la ingestión en algunos países de sal yodada y alimentos ricos en yodo. Esta enfermedad alcanza alrededor del 10 por ciento de las masas mediastínicas. Objetivo: Presentar el caso de un paciente masculino, operado de bocio endotorácico en la provincia de Cienfuegos. Presentación de caso: Se presenta un paciente masculino, de 48 años de edad, que acude a consulta y refiere aumento de volumen del cuello en la región anterior, que se acompaña de decaimiento y en ocasiones disfagia tanto a los alimentos líquidos como a los sólidos. Además, refiere ligera disnea que tolera adecuadamente cuando realiza las actividades de la vida diaria. Por tratarse de una enfermedad poco frecuente, se considera de interés científico publicar el caso para conocimiento de los profesionales dedicados al estudio y tratamiento de las afecciones tiroideas. Conclusiones: El bocio endotorácico es una entidad poco frecuente y en todos los casos requiere de intervención quirúrgica(AU)

Introduction: A goiter is considered intrathoracic when more than 50 percent of the thyroid gland is in the mediastinum; in other words, below the level of the superior thoracic outlet. It is a rare disease that affects approximately 3 percent of the world's population. The incidence of nodular goiter has decreased due to the ingestion of iodized salt and iodine-rich foods in some countries. This disease accounts for about 10 percent of mediastinal masses. Objective: To present the case of a male patient operated on for endothoracic goiter in the province of Cienfuegos. Case presentation: The case is presented of a 48-year-old male patient who comes for consultation referring a volume increase in the anterior neck region, accompanied by decay and sometimes dysphagia to both liquid and solid food. In addition, he reports slight dyspnea that he tolerates adequately when performing daily living activities. Since this is a rare disease, it is considered of scientific interest to publish the case for the knowledge of professionals dedicated to studying and treating thyroid disorders. Conclusions: Endothoracic goiter is a rare entity and, in all cases, requires surgical intervention(AU)

Parentalidade homoafetiva masculina e seus desafios: uma revisão integrativa da literatura / Male homoparenting and its challenges: an integrative literature review

Resumo Este estudo visa elucidar os desafios enfrentados no exercício da parentalidade homoafetiva masculina por meio de uma revisão integrativa da literatura. Seguindo as recomendações PRISMA, foram analisados estudos empíricos dos últimos 22 anos, extraídos das bases de dados PubMed e APA PsychNet. Os descritores "Homosexuality, Male" e "Father" foram empregados para a seleção de artigos relevantes, processo realizado independentemente por dois pesquisadores. Os resultados indicam uma complexidade nas experiências parentais de homens homossexuais, variando entre desafios significativos, como estigmas e preconceitos sociais, e situações sem dificuldades notáveis. A decisão de assumir a paternidade nesse grupo é fortemente influenciada por fatores específicos à realidade homoafetiva, inserida em um contexto social frequentemente não acolhedor. Os achados destacam a importância de compreender as interações entre aspectos individuais, sociais e culturais na formação da homoparentalidade masculina. Este estudo sublinha a necessidade de políticas e práticas inclusivas e sensíveis à diversidade, visando o apoio ao bem-estar familiar em contextos homoafetivos.

Abstract This study aims to elucidate the challenges faced in the exercise of male homoparenting, through an integrative literature review. Following PRISMA guidelines, empirical studies from the last 22 years were analyzed, independently collected by four researchers using the PubMed and APA PsychNet databases, with the descriptors "Homosexuality, Male" and "Father". The results reveal the unique and complex reality faced by homosexual men in the parental context. While some studies highlight significant challenges, such as stigmas and social prejudices, others do not observe such difficulties. The decision to become a father among homosexual men is influenced by factors specific to their reality, in a context where parenthood is not widely accepted. The findings of this study emphasize the need to understand the complex interactions among individual, social, and cultural factors in male homoparenting. In summary, this study highlights the need for inclusive and diversity-sensitive approaches to support family well-being.

Ativismo digital sobre paternidade gay no Instagram: a homoparentalidade masculina em cena / Digital activism about gay fatherhood on Instagram: male homoparenting in the picture

Resumo No Brasil contemporâneo tem sido expressivo tanto o número de homens-pais assumindo o cuidado de seus filhos e filhas, quanto das iniciativas de produção de conteúdo sobre paternidades no Instagram. Este artigo visa analisar as concepções que sustentam o ativismo digital da homoparentalidade no Instagram, a partir dos estudos de gênero com homens. Para tal, realizou-se um estudo qualitativo em ambiência digital, utilizando o método das narrativas de vida. Os resultados foram analisados e divididos nas seguintes seções: projeto de parentalidade; experiência pessoal de paternidade; articulação de agenda política LGBT; quando a paternidade vira um "negócio"; e haters, críticas e reações negativas. Conclui-se que a reflexão sobre a própria experiência de paternidade/masculinidade, atravessada pelo marcador social da diferença orientação sexual e o ativismo por direitos que sustentam a produção de conteúdo. Assim, ressalta-se a singularidade de cada paternidade, pois o fato de ser gay constrói a experiência de paternidade particular para cada homem. Apesar das iniciativas expostas, mudanças ainda são incipientes, visto que o ativismo por direitos coexiste com o avanço de forças conservadoras, que limitam as expressões das alteridades sexuais e de gênero.

Abstract In contemporary Brazil, the number of male fathers taking care of their sons and daughters and the initiatives to produce content about fatherhood on Instagram have been significant. This article aims to analyze the concepts that support the digital activism of homoparenting on Instagram, based on gender studies with men. To this end, a qualitative study was conducted using the life narrative method in a digital environment. The results were analyzed and divided into the following sections: parenting project, personal experience of fatherhood, articulation with LGBT political agenda when parenthood becomes a "business", and haters, criticism, and adverse reactions. It was concluded that the reflection on the experience of fatherhood/masculinity itself is crossed by the social marker of the difference in sexual orientation and the activism for rights that sustain content production. Thus, the uniqueness of each fatherhood is highlighted since the fact of being gay constructs the fatherhood experience for each man. Despite the initiatives brought forth in this study, changes are still in progress, as rights activism coexists with the advancement of conservative forces, which limit the expressions of sexual and gender otherness.

Association between nonalcoholic steatohepatitis and high serum ferritin levels in type 2 diabetes mellitus

SUMMARY OBJECTIVE: The aim of this study was to assess the role of elevated serum ferritin levels in the onset, pathological progression and prognosis of nonalcoholic fatty liver disease. Nonalcoholic fatty liver disease has been rapidly increasing worldwide. Despite extensive research on the pathogenesis of nonalcoholic fatty liver disease, a lack of sufficient clinical research on the relationship between nonalcoholic fatty liver disease and serum ferritin levels remains. METHODS: We analysed 968 patients with type 2 diabetes mellitus who underwent liver ultrasound examination and had their serum ferritin levels measured. The presence of nonalcoholic fatty liver disease and advanced liver fibrosis was determined through abdominal ultrasound examination and the nonalcoholic fatty liver disease fibrosis score. RESULTS: Compared to that in the non-nonalcoholic fatty liver disease group, the presence of hyperferritinemia was significantly more common in the nonalcoholic fatty liver disease group (83.3 vs. 56.3%, p=0.005). When patients with nonalcoholic fatty liver disease were stratified by the nonalcoholic fatty liver disease fibrosis score, those with advanced liver fibrosis exhibited a higher prevalence of hyperferritinemia (56.3, 78.9, and 88.9% for none, simple steatosis, and advanced fibrosis, respectively; p for trend=0.002). In multivariate logistic regression, liver fibrosis was independently associated with hyperferritinemia (odds ratio [OR] 1.45; 95% confidence interval [CI] 1.18-2.02; p=0.014), and this association remained significant in male patients after adjusting for other risk factors (OR 2.66; 95% CI 1.43-5.48; p=0.026). CONCLUSION: Identifying nonalcoholic fatty liver disease patients at a risk of developing nonalcoholic steatohepatitis and advanced fibrosis is crucial for implementing timely interventions and improving patient outcomes. This study highlights the potential utility of serum ferritin levels as a serum biomarker for identifying nonalcoholic steatohepatitis patients and those at a risk of late-stage fibrosis, particularly in male patients with nonalcoholic fatty liver disease.

Analysis of pre-exposure prophylaxis awareness, willingness, uptake patterns, barriers and needs among MSM students and its influencing factors / 中国学校卫生

Objective@#To explore the pre-exposure prophylaxis (PrEP) awareness, willingness, uptake patterns, barriers and needs among Chinese student men who have sex with men (MSM), so as to provide relevant evidence for targeted interventions with PrEP.@*Methods@#A proportional sampling method was used to conduct a cross sectional survey of MSM aged 16 years and older residing in 21 provinces, municipalities, and autonomous regions in mainland China between October 20 and December 20, 2021, to collect information on demographic and sexual behavioral characteristics, and 923 students of them were selected as the subjects of this study. The chi-square test and Fisher s test were used for univariate analysis, followed by multivariate Logistic regression to analyze the influencing factors of PrEP awareness and uptake.@*Results@#According to the cascade analysis method, the awareness, willingness, uptake and adherence rates of PrEP among the student MSM were obtained as 88.95%, 67.36%, 13.20% and 45.21 %, respectively. HIV testing more than once in the last 3 months, and all of them were aware of the HIV test results of their sexual partners, and those with high frequency of condom use had a higher rate of awareness ( OR =2.32, 1.79, 1.69, P <0.05). Willingness rates were higher for those from the pilot city, using substances, and HIV testing more than once in the last 3 months ( OR =2.13, 1.65, 1.69, P <0.05). Higher rates of uptake were found among those from high risk and pilot areas, presence of commercial sex, substance use, and high literacy ( OR =5.60, 3.54,2.81, 1.92, 4.54, P <0.05). Adherence rates were higher among those who used one pill per day or both ( OR =12.77, 13.26, P <0.05). The barriers and needs faced by student MSM were primarily personal concerns about medication side effects, preventative effects, and confidence in sexual behavioral styles, and the high cost of medication and related service costs.@*Conclusions@#The student MSM population in China is characterized by high awareness, low willingness, low uptake, and low adherence to PrEP. Targeted interventions should be considered and tailored by the departments to facilitate PrEP promotion among student MSM.

Transcriptomic Analysis of Wuzi Yanzongwan on Testicular Spermatogenic Function in Semi-castrated Male Mice / 中国实验方剂学杂志

ObjectiveTo screen out the transcriptomes related to the intervention of Wuzi Yanzongwan on the spermatogenic function of semi-castrated male mice， and to explore its potential mechanism in the intervention of the progress of low spermatogenic function. MethodBalb/c mice were randomly divided into sham-operated group， model group， testosterone propionate group（0.2 mg·kg-1·d-1， intramuscular injection） and Wuzi Yanzongwan group（1.56 g·kg-1·d-1， intragastric administration） according to body weight， with 12 mice in each group. The right testicle and epididymis were extracted from the model group and the drug administration group to construct the semi-castrated model of low spermatogenic function， while the fur and the right scrotum of the sham-operated group were only cut and immediately sterilized and sutured. At the end of the intervention， hematoxylin-eosin（HE） staining was used to observe the histopathology of testis， enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of serum testosterone（T）， luteinizing hormone（LH） and follicle stimulating hormone（FSH）. The sperm count and motility of epididymis were measured by automatic sperm detector of small animal. Transcriptomic microarray technology was used to detect the mRNA expression level of testicular tissue in each group， the transcriptome of genes related to the regulation of Wuzi Yanzongwan was screened， and three mRNAs were selected for Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） to verify the transcriptome data. Through the annotation analysis of Gene Ontology（GO） and the signaling pathway analysis of Kyoto Encyclopedia of Genes and Genomes（KEGG）， the related functions of drugs regulating transcriptome were analyzed. ResultCompared with the sham-operated group， the testicular tissue of mice in the model group showed spermatogenic injury， contraction and vacuolization of the seminiferous tubules， reduction of spermatogenic cells at all levels， widening of the interstitial space， obstruction of spermatogonial cell development and other morphological abnormalities， and serum T significantly decreased， LH significantly increased（P<0.01）， and FSH elevated but no statistically significant difference， the count and vitality of epididymal sperm significantly decreased（P<0.01）. There were 882 differentially expressed mRNAs in the testicular tissues， of which 565 were up-regulated and 317 were down-regulated. Cluster analysis showed that these differentially expressed mRNA could effectively distinguish between the sham-operated group and the model group. Compared with the model group， the damage to testicular tissue in the Wuzi Yanzongwan group was reduced， the structure of the seminiferous tubules was intact， vacuolization was reduced， and the number of spermatogenic cells at all levels was significantly increased and arranged tightly. The serum T significantly increased， LH significantly decreased（P<0.01）， and FSH decreased but the difference was not statistically significant. The count and vitality of sperm in the epididymis were significantly increased（P<0.01）. Moreover， Wuzi Yanzongwan could regulate 159 mRNA levels in the testes of semi-castrated mice， of which 32 were up-regulated and 127 were down-regulated， and the data of the transcriptome assay was verified to be reliable by Real-time PCR. GO and KEGG analysis showed that the transcriptome functions regulated by Wuzi Yanzongwan were involved in the whole cell cycle process of sperm development such as sex hormone production of interstitial cells in testis， renewal， differentiation， metabolism， apoptosis and signal transduction of spermatogenic cells， and were closely related to the biological behaviors of signaling pathways such as spermatogenic stem cell function， endoplasmic reticulum protein processing and metabolic program. ConclusionWuzi Yanzongwan can effectively improve the low spermatogenic function of semi-castrated male mice， and its mechanism may be related to the regulation of testicular transcriptional regulatory network， the synthesis of sex hormones in testicular interstitial cells， the function of spermatogenic stem cells， the whole cell cycle process of spermatogenesis， as well as the expression of endoplasmic reticulum protein processing and metabolic program related genes transcription.

Molecular differentiation of coagulase-positive staphylococcal isolates carrying mecA- and PVL-encoding genes among healthy males

Aims@#This study was aimed to monitor the asymptomatic carriage of coagulase-positive staphylococcal bacteria among university male students and detect the prevalence of virulence marker genes that encode methicillin resistance (mecA) and Panton-Valentine leukocidin (PVL) toxin among the isolates.@*Methodology and results@#Single nasal swaps were collected from 144 participating students who resided at four different locations within Al-Madinah city. A total of 112 Gram-positive staphylococcal isolates were recovered from the 144 participants (carriage rate of 77.8%). Coagulase-positive staphylococci were differentiated using duplex PCR amplification of the 16S rRNA and nuc genes and accounted for 30 isolates (carriage rate of 20.8%). These isolates were most prevalent in the northern and southern parts of Al-Madinah city, while the lowest numbers of isolates were detected in students of the eastern part. Coagulase-positive isolates were further phenotypically characterized for methicillin resistance by the disc diffusion method. Uniplex PCR assays were conducted to screen for mecA- and PVL toxin-encoding genes. The mecA gene was amplified from all 15 (50%) methicillin-resistant coagulase-positive isolates, while the PVL toxin-encoding gene was detected in 19 isolates (63.3%), 10 (33.3%) of which contained the mecA gene. Lastly, PCR amplification of the NRPS gene from coagulase-positive isolates revealed the absence of Staphylococcus argenteus, the recently discovered genetically divergent lineage of Staphylococcus aureus.@*Conclusion, significance and impact of study@#An elevated prevalence of coagulase-positive isolates harboring mecA and PVL virulence genes was observed compared with previous investigations. This poses a potential threat if they spread among the population, resulting in outbreaks of community-acquired infections.

Exploration of Thoughts and Possible Therapeutic Mechanism of Treating Male Infertility from the Perspective of Spleen and Kidney by Regulating Intestinal Flora / 广州中医药大学学报

Based on the literature study,the thoughts and possible therapeutic mechanism in treating male infertility from the perspective of spleen and kidney by regulating intestinal flora were explored.Disturbance of intestinal flora is one of the important factors leading to the development of male infertility,and the spleen and kidney have certain similarities to intestinal flora in the physiological function and pathological changes.Moreover,tonifying the kidney and strengthening the spleen can regulate the intestinal flora by fostering the growth of beneficial bacteria,inhibiting the reproduction of pathogenic bacteria,and protecting the barrier of the intestinal mucosa.Therefore,the possible therapeutic mechanisms in treating male infertility with the prescriptions for tonifying the kidney and strengthening the spleen to regulate intestinal flora are as follows:inhibiting the expression of inflammatory factors to reduce the inflammatory reaction of testicular tissues;improving the antioxidant capacity to alleviate the damage of spermatozoa caused by oxidative stress,and improving the bad mood to alleviate the impact of psychological stress on the reproductive system.The exploration of the thoughts for treating male infertility from the perspective of spleen and kidney by regulating intestinal flora may provide a new entry point for modern Chinese medicine clinical treatment of male infertility.
