Depression is associated with poor self-reported adherence to antiretroviral therapy among people living with HIV attending an HIV clinic in the UK: results from a cross-sectional study.

Contemporary evidence is needed to assess whether the prevalence of depression remains high among people living with HIV in the United Kingdom despite recent efforts to improve patients' mental health, and if depression is negatively associated with individuals' adherence to antiretroviral therapy. In a secondary analysis of a cross-sectional clinic-based survey of alcohol consumption and associated health behaviour among people living with HIV in London, of the 221 respondents, 106 (48%) had poor self-reported adherence to antiretroviral therapy (CASE Index) and 69 (31%) screened positive for depression (PHQ-9). Poor self-reported adherence to ART was 72% higher among participants who screened positive for depression in comparison with participants who screened negative. Respondents who were younger, unemployed, and reported problematic drug use were more likely to screen positive for depression. Screening and management of depression as a part of routine HIV care may support adherence to antiretroviral therapy.

Tuberculosis Knowledge among Persons Living with HIV Attending a Tertiary Hospital in Lima, Peru.

Tuberculosis (TB) is the leading cause of death among people living with HIV (PLWH). Limited TB knowledge has been associated with delayed TB diagnosis and low adherence to TB treatment. A cross-sectional study was conducted among PLWH at the largest HIV-referral center in Lima, Peru, to describe TB knowledge among PLWH and potential associated sociodemographic factors. Participants answered a self-administered survey on TB knowledge, which consisted of five questions about TB cure, transmission, treatment, symptoms, and prevention. Of 179 PLWH enrolled, most participants did not know that isoniazid (85%) and antiretrovirals (78%) are preventive measures for TB, and 56 (31.3%) knew that TB can be asymptomatic in PLWH. We did not find statistical differences in TB knowledge based on gender, education, marital status, and time on HIV care. We identified important gaps in TB knowledge among PLWH. Addressing these gaps could empower PLWH to reduce their TB risk.

Cryptosporidium infection and associated risk factors among children from rural areas in Peru: a nested case-control study.

This study aimed to detect the frequency of Cryptosporidium infection and associated risk factors among children from rural areas in Peru. A case-control study was conducted, nested in a cohort in two rural communities that included children between 6 and 13 months who were followed for 6 months. Cases were children whose fecal samples tested positive for Cryptosporidium infection using an immunochromatography test. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) to analyze risk factors associated with Cryptosporidium infection. Among 72 children, 13 (18%) were cases. Cryptosporidium infection was associated with below secondary education of the mother (OR 7.62, 95% CI 1.50-36.72) and with having more siblings living at home (OR 1.71, 95% CI 1.04-2.82). An important frequency of Cryptosporidium infection among children from rural areas in Peru was reported, more research is needed to understand its true burden and risk factors among children in Peru.

Bovine lactoferrin for the prevention of COVID-19 infection in health care personnel: a double-blinded randomized clinical trial (LF-COVID).

Lactoferrin (LF) has in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aimed to determine the effect of bovine lactoferrin (bLF) in the prevention of SARS-CoV-2 infection in health care personnel. A randomized, double-blinded, placebo-controlled clinical trial was conducted in two tertiary hospitals that provide care to patients with SARS-CoV-2 infection in Lima, Peru. Daily supplementation with 600 mg of enteral bLF versus placebo for 90 days was compared. Participants were weekly screened for symptoms suggestive of SARS-CoV-2 infection and molecular testing was performed on suspected episodes. A serological test was obtained from all participants at the end of the intervention. The main outcome included symptomatic and asymptomatic cases. A sub-analysis explored the time to symptomatic infection. Secondary outcomes were the severity, frequency, and duration of symptomatic infection. The study was prematurely cancelled due to the availability of vaccines against SARS-CoV-2 in Peru. 209 participants were enrolled and randomized, 104 received bLF and 105 placebo. SARS-CoV-2 infection occurred in 11 (10.6%) participants assigned to bLF and in 9 (8.6%) participants assigned to placebo without significant differences (Incidence Rate Ratio = 1.23, 95%CI 0.51-3.06, p-value = 0.64). There was no significant effect of bLF on time to symptomatic infection (Hazard Ratio = 1.61, 95%CI 0.62-4.19, p-value = 0.3). There were no significant differences in secondary outcomes. A significant effect of bLF in preventing SARS-CoV-2 infection was not proven. Further studies are needed to assess the effect of bLF supplementation on SARS-CoV-2 infection.Clinical trial registration ClinicalTrials.gov Identifier: NCT04526821, https://clinicaltrials.gov/ct2/show/NCT04526821?term=LACTOFERRIN&cond=COVID-19&cntry=PE&city=Lima&draw=2&rank=1 .

Knowledge, attitudes, and perception of the role of the media regarding COVID-19 in medical students from a peruvian university. / Conocimientos, actitudes y percepción sobre el rol de los medios de comunicación respecto a la COVID-19 en estudiantes de Medicina de una universidad peruana.

A cross-sectional study was carried out on medical students from a private Peruvian university. The aim was to describe knowledge and attitudes towards COVID-19 as well as the student's perception of the role of media outlets and social media. Of the students, 32% did not know that during the first five days of illness, serological tests are preferred for diagnosing COVID-19 over molecular tests; 73% reported being willing to work as a volunteer during the pandemic, and 94% received false information regarding COVID-19 on social media. This study demonstrated that information regarding diagnostic tests should be reinforced and that the high percentage of students willing to volunteer during the COVID-19 pandemic should not be overlooked.

Se realizó un estudio transversal en estudiantes de Medicina de una universidad privada de Lima. El objetivo fue describir el nivel de conocimientos y las actitudes sobre la COVID-19, además de su percepción sobre el rol de los medios de comunicación y de las redes sociales. El 32% no sabía que en los primeros cinco días de la enfermedad, las pruebas serológicas son preferibles para diagnosticar la COVID-19, comparadas con las pruebas moleculares; el 73% reportó estar dispuesto a trabajar como voluntario durante la pandemia y el 94% recibió información falsa sobre la COVID-19 en las redes sociales. Este estudio demuestra que la información sobre el uso de pruebas diagnósticas debe ser reforzada y que se debe tomar en cuenta el alto porcentaje de estudiantes dispuestos a ser voluntarios durante la pandemia de la COVID-19.

Knowledge, attitudes and practices of parents towards antibiotic use in rural communities in Peru: a cross-sectional multicentre study.

BACKGROUND: The inappropriate use of antibiotics significantly contributes to the development of antibiotic resistance. There is limited information about the use of antibiotics among parents from rural areas in Peru. This study aimed to describe the knowledge, attitudes and practices towards antibiotics among parents of children < 5 years of age from rural communities in Peru; to explore the association between knowledge and attitudes towards antibiotics and to explore determinants of low knowledge and self-medicating his/her child with antibiotics. METHODS: Cross-sectional study in six rural primary health centres in Peru using a self-administered survey. Crude and adjusted Prevalence Ratios (PR), and 95% Confidence Intervals (95% CI) were calculated to explore determinants of low knowledge and of having self-medicated his/her child with antibiotics. Linear regression was used to explore the association between knowledge and attitudes. RESULTS: A total of 231 parents were included. The largest gap in knowledge was among 183 parents (79%) who did not know that antibiotics cannot cure viral infections. The largest gap in attitudes was among 185 participants (80%) that did not disagree with "If I want my child to receive antibiotics, I would not be satisfied if the doctor refuses to prescribe them". More than half of parents (n = 120, 52%) reported having self-medicated his/her child with antibiotics. A positive correlation was found between knowledge and attitudes (Coefficient 0.53, 95% CI 0.38-0.68) after adjusting for the age and the education of the parent. Parents who were < 20 years old were more likely to have low knowledge about antibiotics (crude PR 2.39, 95% CI 1.32-4.34) compared to those aged > 40 years. Parents who had self-medicated his/her child with antibiotics (n = 120, 52%) were more likely to have purchased antibiotics without prescription (aPR 2.70, 95% CI 1.74-4.19) and to have received antibiotics after the recommendation of a pharmacist (aPR 1.79, 95% CI 1.13-2.82). CONCLUSIONS: Knowledge about antibiotics among parents from rural settings in Peru is limited and highlights the need for educational interventions. Public health policies to limit the acquisition of antibiotics without prescription should be implemented.

HIV and antiretroviral treatment knowledge gaps and psychosocial burden among persons living with HIV in Lima, Peru.

This study aims to describe knowledge on HIV and antiretroviral (ARV) treatment and psychosocial factors among people living with HIV (PLWH) in Lima, Perú, to explore characteristics associated to this knowledge, and determine its impact on sustained viral suppression. A cross-sectional survey was conducted among 171 PLWH at the largest referral health care center in Lima. The psychosocial factors measured were depression, risk of alcoholism, use of illegal drugs and disclosure. A participant had "poor knowledge" when less than 80% of replies were correct. Sustained viral suppression was defined as two consecutive viral loads under 50 copies/mL. A total of 49% and 43% had poor HIV and ARV knowledge respectively; 48% of the study population screened positive for depression and 27% reported feeling unsupported by the person they disclosed to. The largest gaps in HIV and ARV knowledge were among 98 (57%) that did not recognize that HIV increased the risk of cancer and among 57 (33%) participants that did not disagree with the statement that taking a double dose of ARV if they missed one. Moderate depression was significantly associated to poor HIV and ARV knowledge. Non-disclosure and being on ARVs for less than 6 months were associated with not achieving sustained viral suppression. Our findings highlight important HIV and ARV knowledge gaps of PLWH and a high burden of psychosocial problems, especially of depression, among PLWH in Lima, Peru. Increasing knowledge and addressing depression and disclosure could improve care of PLWH.

Killing of Cryptosporidium sporozoites by Lactoferrin.

Intestinal infection caused by Cryptosporidium is a major contributor to diarrhea morbidity and mortality in young children around the world. Current treatments for children suffering from cryptosporidiosis are suboptimal. Lactoferrin is a glycoprotein found in breast milk. It has showed bacteriostatic and antimicrobial activity in the intestine. However, the effects of lactoferrin on the intestinal parasite Cryptosporidium have not been reported. In this study, we investigated the anticryptosporidial activity of human lactoferrin on different stages of Cryptosporidium. Physiologic concentrations of lactoferrin killed Cryptosporidium parvum sporozoites, but had no significant effect on oocysts viability or parasite intracellular development. Since sporozoites are essential for the infection process, our data reinforce the importance of breastfeeding and point to the potential of lactoferrin as a novel therapeutic agent for cryptosporidiosis.

Study on the microflora and biochemistry of cocoa fermentation in the Dominican Republic.

Cocoa fermentation was monitored at the IDIAF (Instituto Dominicano de Investigaciones Agropecuarias y Forestales) "Mata Larga" experimental station, in San Francisco de Macoris, Dominican Republic. The maximum average fermentation temperature reached 51 degrees C after 48 h and the pH reached 4.5 after 144 h of fermentation. A significant decrease in glucose, fructose and citric acid was seen in the pulp over the first 48 h. There was a delay of 24 h between maximum microbial growth and maximum concentrations of the respective metabolites, which occurred after 48 h for ethanol and after 72 h for acetic acid. A maximum concentration in lactic acid was found after around 120 h of fermentation. The aerobic mesophilic flora increased from 6.1x10(6) to a maximum of 4.2x10(7) CFU g(-1) of dry matter after 48 h of fermentation. Yeasts displayed maximum development after 24 h (6.1x10(7) CFU g(-1) of dry matter), whilst for lactic and acetic acid bacteria it occurred after 48 h (7.3x10(7) and 1.5x10(8) CFU g(-1) of dry matter respectively). The yeasts isolated belonged to the genera Hanseniaspora and Candida, the lactic acid bacteria to the genus Lactobacillus, and the acetic acid bacteria to the genus Acetobacter. The differences compared to other fermentation trials concerned the micropopulation from a qualitative point of view.
