Zika virus infection in pregnant women and their children: A review.

Zika virus (ZIKV) is an arthropod-borne virus (arbovirus) transmitted primarily by Aedes mosquitoes. ZIKV can be transmitted to humans by non-vector borne mechanisms such as sexual intercourse, maternal-foetal transmission or blood transfusion. In 2015, ZIKV emerged in the Americas, and spread to 87 countries and territories with autochthonous transmission, distributed across four of the six WHO regions. Most ZIKV infections in pregnancy are asymptomatic, but mother to child transmission of the virus can occur in 20 to 30% of cases and cause severe foetal and child defects. Children exposed to ZIKV while in utero might develop a pattern of structural anomalies and functional disabilities secondary to central nervous system damage, known as congenital Zika syndrome, and whose most common clinical feature is microcephaly. Normocephalic children born to mothers with ZIKV infection in pregnancy, and with no observable Zika-associated birth defects, may also present with later neurodevelopmental delay or post-natal microcephaly. Screening and detection of ZIKV infection in pregnancy is essential, because most women with ZIKV infection are asymptomatic and clinical manifestations are non-specific. However, the diagnosis of ZIKV infection poses multiple challenges due to limited resources and scarce laboratory capabilities in most affected areas, the narrow window of time that the virus persists in the bloodstream, the large proportion of asymptomatic infections, and the cross-reactivity with other flaviviruses such as Dengue virus (DENV). Molecular methods (RT-PCR) are the most reliable tool to confirm ZIKV infection, as serodiagnosis requires confirmation with neutralization tests in case of inconclusive or positive serology results. Prenatal ultrasound assessment is essential for monitoring foetal development and early detection of possible severe anomalies. A mid- and long-term follow-up of children exposed to ZIKV while in utero is necessary to promptly detect clinical manifestations of possible neurological impairment. Tweetable abstract: Zika virus infection during pregnancy is a cause of pregnancy loss and disability in children. Protection against mosquito bites, access to sexual and reproductive health services, prompt screening and detection of ZIKV infection in pregnancy, and prenatal ultrasound monitoring are key control strategies whilst a vaccine is not available.

Brain-derived neurotrophic factor among patients with alcoholism.

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is involved in neurogenesis and in the protection against oxidative damage and neuronal apoptosis. After exercise, there is an increased expression of this myokine, especially in skeletal muscle and brain. Low BDNF levels have been described in neurodegenerative diseases. Alcoholics show both muscle atrophy and brain atrophy. Thus, this study was performed in order to analyze serum BDNF levels among alcoholics and their associations with brain atrophy and muscle strength. METHODS: Serum BDNF values were determined to 82 male alcoholics and 27 age-matched controls, and compared with handgrip strength, with the presence of brain atrophy, assessed by computed tomography, and with the intensity of alcoholism and liver function derangement. RESULTS: BDNF levels and handgrip strength were significantly lower among patients. Handgrip strength was correlated with BDNF values, both in the whole population and in alcoholics, especially in patients over 59 years of age. BDNF was poorly related to liver dysfunction but showed no relationship with brain atrophy or age. CONCLUSION: Chronic alcoholics show decreased BDNF serum levels that are related to muscle function impairment rather than to age, brain atrophy, liver dysfunction, or the amount of ethanol consumed.

High-risk human papillomavirus infection and associated factors in the anal canal of HIV-positive patients in Medellín, 2017-2018.

OBJECTIVE: To estimate the prevalence of high-risk human papillomavirus (HR-HPV) anal infection and associated factors in human immunodeficiency virus (HIV) positive patients in Medellín. METHODS: Descriptive cross-sectional study in 300 HIV-positive patients, adults, with history of anal intercourse, treated in two health care services of Medellín 2017-2018. We conducted a structured survey on sociodemographics, sexual behavior and medical history. HPV was detected in anal swabs tested by the COBAS 4800 system. Exploratory data analysis of risk factors associated with HR-HPV was conducted by chi-square test of independence and both raw and adjusted prevalence ratios used the Poisson regression model, at a 95% confidence interval. RESULTS: The high-risk HPV had a prevalence of 82.7%; HPV16 had a prevalence of 32.7%, HPV18 a prevalence of 21.7% and other HPV types scored 78.3%. The high-risk HPV prevalence in women was of 68.2% and 83.8% in men. The risk factors associated with high-risk HPV after adjustment were age under 30 years, elementary education, casual sex partners, and first sexual activity before 18 years old. CONCLUSIONS: The high incidence of high-risk HPV, along with the occurrence of coinfections by multiple types in the study population shows their susceptibility to develop some type of anal intra-epithelial neoplasia. It is important to establish sexual health programs focused on primary health care.

Handgrip strength and lean mass are independently related to brain atrophy among alcoholics.

BACKGROUND: In neurodegenerative disorders or in normal aging humans a relationship between muscle mass and/or performance and brain volume was observed, that is not dependent on age or other confounding factors. The aim of the present study is to analyse the relationship between lean mass and handgrip strength in alcoholics, who frequently show brain and muscle atrophy. METHODS: It was included 101 male patients aged 58.35 ± 11.59 years, and 44 controls, all of them workers of our hospital, drinkers of less than 20 g ethanol/day, of similar age. Patients and controls underwent dominant handgrip assessment with a Collins' dynamometer, whole body composition analysis by densitometry, and brain computed tomography (CT) examination, with further calculation of several indices indicative of brain atrophy. MAIN RESULTS: 1) Brain atrophy is a very common finding among alcoholics, both among cirrhotics and non-cirrhotics. 2) Alcoholics show a marked reduction in handgrip strength, and also in lean mass, especially at the arms and legs -but not in the trunk, even if patients with ascites were excluded.3) There is a relationship between reduced lean mass and brain atrophy, and a close correlation between handgrip strength and brain atrophy, that is independent of age and liver function. 4) Total fat amount is not different among alcoholics and controls, but there are marked differences in fat distribution: alcoholics show less fat in arms, but more fat in trunk, so that if we calculate the peripheral fat/trunk fat index, marked differences were observed among alcoholics and controls. Neither total fat nor fat distribution were related to brain atrophy. CONCLUSION: among alcoholics, as in other neurodegenerative conditions, there is a relationship between reduced lean mass and brain atrophy, and a close correlation between handgrip strength and brain atrophy, that is independent of age, duration of ethanol consumption and liver function.

Equine Chorionic Gonadotropin (eCG) improves bucks' semen quality during the nonbreeding season.

In most goat breeds, testosterone serum concentration and semen quality decrease during the nonbreeding season. However, bucks reproductive activity may be stimulated with the administration of equine chorionic gonadotropin (eCG). Therefore, the aim of this study was to determine whether the repeated administration of eCG stimulates the reproductive status of bucks during the nonbreeding season. The study was performed with 19 bucks that were assigned to a group that was treated with eCG (GeCG) and an untreated control group (GCon). The GeCG bucks received an initial dose of 800 IU of eCG (Day 0), followed by four doses of 500 IU administered every 5 days beginning on Day 5. Serum testosterone and anti-eCG antibody concentrations, testicular and seminal traits were determined until Day 60. Testosterone concentration (from Day 3 to 21: p < 0.0001), anti-eCG titre (from Day 12 to 44: p ≤ 0.01), percentage of motile spermatozoa (Day 6: p = 0.006 and 14: p = 0.001) and of spermatozoa with progressive motility (Day 6: p = 0.01 and 14: p = 0.002) and the percentage of spermatozoa with functional membrane (Day 6: p = 0.02 and 22: p = 0.008) were higher in GeCG than in GCon bucks. Also in frozen-thawed samples, the percentage of motile spermatozoa tended to be higher in GeCG than that of GCon bucks (p = 0.07). In conclusion, the administration of eCG during the nonbreeding season stimulated the secretion of testosterone and improved fresh and possibly frozen-thawed semen quality. However, it also resulted in an increase in anti-eCG antibody titre.

Soluble Klotho and Brain Atrophy in Alcoholism.

AIM: Fibroblast growth factor (FGF-23) and α-Klotho (Klotho) levels may be altered in inflammatory conditions, possibly as compensatory mechanisms. Klotho exerts a protective effect on neurodegeneration and improves learning and cognition. No data exist about the association of Klotho and FGF-23 levels with brain atrophy observed in alcoholics. The aim of this study is to explore these relationships. SHORT SUMMARY: FGF-23 and Klotho levels are altered in inflammation, possibly as compensatory mechanisms. Klotho enhances learning, but its role in ethanol-mediated brain atrophy is unknown. We found higher FGF-23 and lower Klotho levels in 131 alcoholics compared with 41 controls. Among cirrhotics, Klotho was higher and inversely related to brain atrophy. METHODS: The study was performed on 131 alcoholic patients (54 cirrhotics) and 41 age- and sex-matched controls, in whom a brain computed tomography (CT) was performed and several indices were calculated. RESULTS: Marked brain atrophy was observed among patients when compared with controls. Patients also showed higher FGF-23 and lower Klotho values. However, among cirrhotics, Klotho values were higher. Klotho was inversely related to brain atrophy (for instance, ventricular index (ρ = -0.23, P = 0.008)), especially in cirrhotics. Klotho was also directly related to tumor necrosis factor (TNF) alpha (ρ = 0.22; P = 0.026) and inversely to transforming growth factor (TGF)-ß (ρ = -0.34; P = 0.002), but not to C-reactive protein (CRP) or malondialdehyde levels. FGF-23 was also higher among cirrhotics but showed no association with CT indices. CONCLUSIONS: Klotho showed higher values among cirrhotics, and was inversely related to brain atrophy. FGF-23, although high among patients, especially cirrhotics, did not show any association with brain atrophy. Some inflammatory markers or cytokines, such as CRP or TGF-ß were related to brain atrophy.

Lipid profile and bone mineral density in heavy alcoholics.

BACKGROUND & AIMS: Some studies have illustrated the association between serum lipid profile and bone mineral density (BMD) or fractures. None of these studies was performed among alcoholics, despite the fact that alcoholism may affect both bone mass and lipid metabolism. We here analyse the relationship of serum lipid profile with bone mass among a population of 280 heavy alcoholics (29 women). METHODS: patients underwent a densitometric assessment of BMD and determination of a serum lipid panel. Castelli index (Total cholesterol/HDL cholesterol) and the LDL/HDL cholesterol index were calculated. RESULTS: There was a direct correlation between both total cholesterol and LDL-cholesterol and femoral neck (r = 0.17 and r = 0.20, respectively) and lumbar spine (r = 0.16 and r = 0.20) T score, total BMD (r = 0.14 and r = 0.18) or pelvis BMD (r = 0.16 and r = 0.23; p < 0.025 in all cases). HDL-cholesterol showed no relationship with BMD. Serum triglycerides were also directly related to T score at the lumbar spine (ρ = 0.13; p = 0.032) and pelvis BMD (ρ = 0.13; p = 0.037). Pelvis BMD was significantly related to Castelli index (ρ = 0.15) and LDL/HDL index (ρ = 0.18; p < 0.015 in both cases). Multivariate analysis showed that the association between the serum lipid panel and BMD was independent of liver function and body mass index. CONCLUSIONS: Therefore, BMD was directly related to total cholesterol and LDL cholesterol in heavy alcoholism. This counter intuitive observation adds to others derived from several similar studies conducted in different population groups but not in alcoholics as of yet. The mechanisms that explain the association between serum lipids and bone metabolism need further investigation.

Alpha Klotho and Fibroblast Growth Factor-23 Among Alcoholics.

AIMS: Alcoholism may be a cardiovascular risk factor. Osteocyte derived molecules such as fibroblast growth factor 23 (FGF-23) and soluble α Klotho have recently been associated with cardiovascular disease, but their role in alcoholics is unknown. We here analyze the behavior of FGF23 and α Klotho in alcoholics. METHODS: Ninety-seven alcoholic patients were assessed for liver function, presence of hypertension, diabetes, atrial fibrillation, left ventricular hypertrophy (LVH), vascular calcifications (assessed by chest X-ray) and nutritional status (lean and fat mass measured by densitometry). We measured plasma levels of FGF-23 and serum soluble α Klotho, using ELISA in 97 patients and 20 age- and sex-matched controls. RESULTS: FGF-23 levels were higher in patients than in controls (Z = 3.50; P < 0.001). FGF-23 (Z = 5.03; P < 0.001) and soluble α Klotho (Z = 5.61; P < 0.001) were higher in cirrhotics, and both were related to liver function, independently of serum creatinine FGF-23 levels were higher among alcoholics with diabetes (Z = 2.55; P = 0.011) or hypertension (Z = 2.56; P = 0.01), and increased body fat (ρ = 0.28; P = 0.022 for trunk fat), whereas α Klotho levels were higher in patients with LVH (Z = 2.17; P = 0.03) or atrial fibrillation (Z = 2.34; P = 0.019). CONCLUSIONS: FGF-23 was higher in alcoholics than in controls, especially among cirrhotics, and soluble α Klotho levels were also higher among cirrhotics. Both were related to liver function impairment, independently of serum creatinine levels, and also showed significant associations with vascular risk factors, such as hypertension, diabetes or trunk fat amount in the case of FGF-23, or LVH or atrial fibrillation in the case of α Klotho. SHORT SUMMARY: We report increased values of fibroblast growth factor 23 (FGF-23) and soluble α Klotho in cirrhotic alcoholics. Both molecules are associated with liver function impairment, and with some cardiovascular risk factors such as diabetes, hypertension, increased body fat, left ventricular hypertrophy and atrial fibrillation independently of serum creatinine.

Atrophy of the corpus callosum in heavy alcoholic patients

Atrophy of the corpus callosum among alcoholics was classically restricted to patients affected by Marchiafava-Bignami (MB) disease. It was further observed in patients with thiamine and/or niacin deficiency, or in alcoholics who had consumed alcoholic beverages for a long period. A 42-year-old alcoholic patient was admitted with a full-blown alcohol withdrawal syndrome. After recovery, unstable gait and marked pyramidal signs were observed. A brain magnetic resonance was performed, which revealed corpus callosum atrophy. At discharge the patient was placed under ambulatory care. Nevertheless, he never attended his appointments and he was readmitted several times with withdrawal syndrome. Repeated MRI studies showed no remarkable changes besides progressive atrophy of the corpus callosum. Indeed, the area of corpus callosum was markedly reduced when compared with that of 20 alcoholics and 5 further patients with Wernicke´s encephalopathy. Therefore, the clinical picture is consistent with classic MB disease, and the more severe atrophy than that observed in the remaining alcoholics suggests that additional mechanisms may play a role in MB disease

Pulmonary thromboembolism in a patient with May-Thurner syndrome: a case report

A 41-year-old woman was admitted to the emergency room with symptoms compatible with deep vein thrombosis affecting the left lower extremity and pulmonary thromboembolism. A CT scan was consistent with pulmonary emboli and thrombosis of the iliac veins extending to the inferior vena cava, which persisted even after correct systemic fibrinolytic therapy. For this reason, a venography was performed and local thrombolysis was administered. Venography revealed a compression of the left common iliac vein caused by the right common iliac artery, so that the patient was diagnosed with May-Thurner syndrome. The clinical features of this anatomical condition and sometimes lethal clinical syndrome are discussed

Homocysteine, Liver Function Derangement and Brain Atrophy in Alcoholics.

AIMS: Hyperhomocysteinemia may be involved in the development of brain atrophy in alcoholics. Its pathogenesis is multifactorial. In the present study, we analyse the relationship between homocysteine levels and brain atrophy, and the relative weight of co-existing factors such as liver function impairment, the amount of ethanol consumed, serum vitamin B12, B6, and folic acid levels on homocysteine levels and brain alterations in alcoholic patients. METHODS: We included 59 patients admitted to this hospital for major withdrawal symptoms and 24 controls. The mini-mental state examination test and a brain computed tomography (CT) scan were performed and several indices were calculated. Serum levels of homocysteine, folic acid, vitamin B6 and vitamin B12 were determined. Liver function was assessed by Child-Pugh score. The daily consumption of ethanol in grams per day and years of addiction were recorded. RESULTS: A total of 83.6% and 80% of the patients showed cerebellar or frontal atrophy, respectively. Patients showed altered values of brain indices, higher levels of homocysteine and vitamin B12, but lower levels of folic acid, compared with controls. Homocysteine, B12 and liver function variables showed significant correlations with brain CT indices. Multivariate analyses disclosed that Pugh's score, albumin and bilirubin were independently related to cerebellar atrophy, frontal atrophy, cella index or ventricular index. Serum vitamin B12 was the only factor independently related to Evans index. It was also related to cella index, but after bilirubin. Homocysteine levels were independently related to ventricular index, but after bilirubin. CONCLUSION: Vitamin B12 and homocysteine levels are higher among alcoholics. Liver function derangement, vitamin B12 and homocysteine are all independently related to brain atrophy, although not to cognitive alterations. SHORT SUMMARY: Hyperhomocysteinemia has been described in alcoholics and may be related to brain atrophy, a reversible condition with an obscure pathogenesis. We studied 59 patients and found that liver function derangement, vitamin B12 and homocysteine levels are all independently related to brain atrophy assessed by computed tomography, although we found no association between these parameters and cognitive alterations.

Thrombin activation and liver inflammation in advanced hepatitis C virus infection.

Hepatitis C virus (HCV) infection is associated with increased thrombotic risk. Several mechanisms are involved including direct endothelial damage by the HCV virus, with activation of tissue factor, altered fibrinolysis and increased platelet aggregation and activation. In advanced stages, chronic HCV infection may evolve to liver cirrhosis, a condition in which alterations in the portal microcirculation may also ultimately lead to thrombin activation, platelet aggregation, and clot formation. Therefore in advanced HCV liver disease there is an increased prevalence of thrombotic phenomena in portal vein radicles. Increased thrombin formation may activate hepatic stellate cells and promote liver fibrosis. In addition, ischemic changes derived from vascular occlusion by microthrombi favor the so called parenchymal extinction, a process that promotes collapse of hepatocytes and the formation of gross fibrous tracts. These reasons may explain why advanced HCV infection may evolve more rapidly to end-stage liver disease than other forms of cirrhosis.

Objetivo: determinar la prevalencia de ITS en adolescentes y conocer los factores de riesgo más frecuentes para adquirirlas. Materiales y métodos: estudio de corte, entre 2010-2013, en 569 estudiantes de Medellín. Se hicieron una encuesta y tamización para VHB, sífilis, VIH, VPH, infección gonocócica, Chlamydia trachomatis, vaginosis bacteriana, candidiasis y uretritis masculina no gonocócica. Resultados: las frecuencias en mujeres fueron las siguientes: VPH 28,1 %; C. trachomatis 11,4 %; vaginosis bacteriana 42,7 % y candidiasis 14,1 %. En 6,2 % de los hombres se halló uretritis no gonocócica. Ni en hombres ni en mujeres se hallaron VHB, sífilis, VIH o infección gonocócica. Los siguientes fueron los factores de riesgo más frecuentes: comenzar las relaciones sexuales antes de los 15 años (59,9 %), no utilizar condón (58,2 %) o no haberlo utilizado en la última relación sexual (41,7 %), no tener conocimientos adecuados sobre salud sexual (39,1 %), tener historia de 3 o más parejas sexuales (30,6 %), tener parejas sexuales diez o más años mayores que ellos (20,4 %), tener relaciones sexuales con personas diferentes a la pareja formal (18,8 %). Conclusiones: la alta prevalencia de ITS en adolescentes que apenas inician su vida sexual debe ser un llamado de atención para poner en práctica programas de salud sexual de alto impacto.

Objective: To determine the prevalence of sexually transmitted infections in a group of adolescents in Medellín, Colombia, and the most frequent risk factors for acquiring them. Materials and methods: Cross-sectional study, between 2010 and 2013, in 569 students who had started sexual intercourse. A questionnaire was applied, and screening was done for the following infections: hepatitis B, syphilis, HIV, HPV, gonorrhea, Chlamydia trachomatis, bacterial vaginosis, candidiasis, and nongonococcal urethritis in men. Results: Women had the following frequencies of infections: HPV 28.1 %; Chlamydia trachomatis 11.4 %; bacterial vaginosis 42.7 %; candidiasis 14.1 %. Nongonococcal urethritis was found in 6.2 % of men. Hepatitis B, syphilis, HIV, and gonococcal infections were not found. The most frequent risk factors were as follows: to have started sexual relations before the age of 15 (59.9 %); not to use condom (58.2 %); not to have utilized condom in the last sexual intercourse (41.7 %); to lack adequate knowledge on sexual health (39.1 %); to have had three or more sexual partners (30.6 %); to have had sexual partners 10 or more years older than themselves (20.4 %), and to have sexual relations with persons different from the formal partner (18.8 %). Conclusions: The high prevalence of STIs in teenagers that are just starting sexual life must be an alert to implement high impact sexual health programs.

Conclusões: a alta prevalência de ITS em adolescentes que mal iniciam sua vida sexual deve ser um chamado de atendimento para pôr em prática programas de saúde sexual de alto impacto.

Lo que no se ve, no existe: percepciones sobre cáncer y papilomavirus humano en jóvenes universitarios, Medellín, Colombia, 2014 / What You Can't See Does Not Exist: What College Students Think about Cancer and the Human Papillomavirus. Medellín, Colombia, 2014 / O que não se vê não existe: percepçóes sobre o câncer e papilomavírus humano em jovens universitários. Medellín (Colômbia), 2014

Objetivo: comprender las percepciones de los estudiantes de pregrado de la Universidad de Antioquia, Colombia, sobre los cánceres de cuello uterino, canal anal, orofaringe y pene, y cómo los relacionan con la infección por PVH. Materiales y métodos: estudio etnográfico, realizado de marzo del 2013 a abril del 2014, participaron 23 mujeres y 14 hombres en ocho grupos de discusión. Sus discursos fueron grabados, transcritos y analizados con el método argumentativo. Resultados: en general, los/as jóvenes relacionaron el cáncer cervicouterino con el PVH, pero no con los tipos de cáncer en canal anal, orofaringe y pene, sobre los cuales tenían poco conocimiento o desconocían. El pensar que las mujeres son las que contraen el cáncer cervical y contagian a los hombres con el PVH no les permitió imaginar que existieran otros cánceres asociados al PVH. Conclusión: las percepciones y la falta de claridad en la relación PVH y otros cánceres, pueden incrementar el riesgo de infección por las prácticas sexuales y en el tiempo aumentar la prevalencia de estos cánceres.

Objective: Understand what undergraduate students at the University of Antioquia think about cervical, anal, oropharyngeal and penile cancer, and how they associate these types of cancer with human papillomavirus (HPV) infection. Materials and Methods: This is an ethnographic study conducted during the period from March 2013 to April 2014. It included 23 women and 14 men who were divided into eight discussion groups. What they had to say was recorded, transcribed and analyzed using the argumentative method. Findings: Overall, the young people who took part in the study associate HPV with cervical cancer, but not with anal, oropharyngeal and penile cancer. In fact, they had little knowledge or knew nothing about those types of cancer. Thinking that women are the ones who contract cervical cancer and infect men with HPV prevented them from imagining there might be other types of cancer associated with HPV infection. Conclusion: Ignorance among women about other types of cancer associated with HPV infection might cause them to neglect preventive measures and increase the risk of infection through sexual practices. The study ratifies the need to develop programs to promote health and to prevent infection with this virus.

Objetivo: compreender as percepçóes dos estudantes de graduação da Universidad de Antioquia sobre os cánceres de colo uterino, canal anal, orofaringe, pênis e como os relacionam com a infecção por papilomavírus humano (HPV). Materiais e métodos: estudo etnográfico realizado de março de 2013 a abril de 2014; participaram 23 mulheres e 14 homens em oito grupos de discussão. Seus discursos foram gravados, transcritos e analisados com o método argumentativo. Resultados: em geral os(as) jovens relacionaram o cáncer cérvico-uterino com o HPV, mas não com os tipos de cáncer em canal anal, orofaringe e pênis, sobre os quais tinham pouco conhecimento ou desconheciam. O fato de pensar que as mulheres são as que contraem o cáncer cervical e contagiam os homens com o HPV não lhes permitiu imaginar que existissem outros cánceres associados com o HPV. Conclusão: o desconhecimento das mulheres sobre a associação do HPV com o risco de padecer de outros cánceres podem ocasionar descuido nas medidas preventivas e aumentar o risco de infecção por práticas sexuais e ratifica-se a necessidade de desenvolver programas encaminhados à promoção da saúde e à prevenção da infecção por esse vírus.
