Carrageenan, an extract from red algae, was identified over a decade ago as a potent inhibitor of human papillomavirus (HPV) infection in vitro. After this discovery, several studies evaluated carrageenan's anti-HPV activity in cells, experimental animals, and humans. We reviewed the evidence for carrageenan's anti-HPV activity. Studies had to be in vitro, in vivo, or in humans and report on carrageenan's anti-HPV activity. Of the 39 records identified in PubMed and 29 records in Clinicaltrials.gov, 22 records were included after screening 8 in vitro (including 2 ex vivo), 3 in vivo, 5 in vitro and in vivo, 3 clinical studies, and 3 trial protocols. A total of 12 studies evaluated carrageenan exclusively, whereas 7 considered carrageenan combined with additional antiviral or other agents. One study protocol will evaluate carrageenan exclusively, and 2 others will evaluate carrageenan-combination products. Most clinical studies evaluated carrageenan's ability to prevent HPV acquisition (n = 4), whereas one sor in combination with other antiviral agents, might be a potential prevention strategy complementary to HPV vaccination for women.

A pilot program was implemented to assess the feasibility of emergency department (ED) preexposure prophylaxis (PrEP) referral. Of 119 eligible patients approached and assessed, 39 (33%) expressed interest and were referred to peer navigators. Of these, 16 (41%) scheduled for appointments; four (10%) initiated PrEP, which demonstrated ED-based PrEP referral was feasible.

Antiretroviral therapy (ART) efficacy for HIV prevention among discordant couples has been demonstrated in clinical trials. Effectiveness outside of research settings is less well understood.

HIV-discordant couples were enrolled in couples' testing and follow-up at 20 government clinics in Kigali from 2010 to 2014. We performed viral linkage analysis on seroconverting couples to determine infection sources (intracouple vs. extracouple). Antiretroviral therapy use in index partners was collected at baseline and during follow-up by self-report with verification of government medical records.

A total of 3777 HIV-discordant couples were identified and followed up at government health clinics. Fifty-four incident HIV infections were identified, of which 36 were confirmed linked to the index partner, 4 were unlinked, and 14 were unknown. Among the 50 linked or unknown transmission pairs, 38% occurred among couples in which the index partner was on ART (HIV incidence rate of 0.63/100 person-years), whereas 62%dant couples identified via couples' voluntary counseling and testing, with increased efforts to improve uptake, adherence, and viral load monitoring.

Rectal and oral Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) infections are common among people with HIV, especially men who have sex with men (MSM); however, GC/CT testing rates remain low in many HIV clinics. We evaluated the real-world implementation and results of extragenital nucleic acid amplification testing for GC/CT in an urban HIV clinic.

Electronic health records were reviewed for all patients 18 years or older with ≥1 outpatient visit to an HIV clinic in Dallas, TX, from February 2016 to May 2019. Extragenital nucleic acid amplification testing became available in February 2017, which was followed by active interventions to increase testing.

Overall, 5564 individual patients were included in the preintervention period (February 2016-January 2017), 5067 in the intervention period (February 2017-August 2017), and 7030 in the postintervention period (September 2017-May 2018). Tailored education was provided to patients, and nursing and medical providers, and a self-collection protocol was implemented beginning in spring 2017. A sustained increase in extragenital GC/CT testing among MSM patients, from 70% to 87% (P < 0.01), was observed. Among MSM, overall GC positivity increased from 3.2% to 8.5% and CT positivity increased from 3.9% to 8.3%. N. gonorrhoeae/C. trachomatis infections were highest among young (<35 years) MSM, and approximately 50% of GC/CT infections diagnosed were detected by oral and rectal tests.

Clinic-wide education and self-collection of extragenital specimens were associated with increased GC/CT testing and detection in a large HIV clinic.

It is still not clear what influences hemoglobin has on the outcomes of patients with sepsis. The intention of this research is to investigate the impact of early hemoglobin levels on clinical outcomes for sepsis.

In this single-center, cohort study, each patient was put into one of four groups dependent on hemoglobin levels of 70 g/L, 80 g/L, or 90 g/L in the first 48 h of being admitted to intensive care unit (ICU). Adjustments for baseline/confounding factors were made using the multiple Cox regression model.

In all, 235 septic patients were examined in this research. The non-survivors exhibited significantly higher levels for early hemoglobin status at or below 80 g/L (33.7% vs. 19.4%, P = 0.016) than survivors. Survival curve demonstrated that septic patients with early hemoglobin levels at or below 80 g/L survived at significantly lower rates than those with hemoglobin above 80 g/L. Multivariate Cox analysis demonstrated that levels of 1-year mortality rose as early hemoglobin levels fell in the first 48 h after ICU admission, with relative risks for 80 g/L to 90 g/L, 70 g/L to 80 g/L, and at or below 70 g/L being respectively 1.11 (95% CI 0.654-1.882), 1.742 (95% CI 0.969-3.133), 1.981 (95% CI 1.124-3.492) times higher than those for hemoglobin levels above 90 g/L.

Hemoglobin levels at or below 80 g/L in the first 48 h after ICU admission are an alternative indicator for predicting long-term mortality of sepsis. Awareness should be encouraged of the importance of targeting early hemoglobin levels when treating sepsis to improve prognosis.

We present 2 cases in infants of disseminated tuberculosis complicated by pneumatoceles with different evolution. This complication should be considered if worsening of respiratory symptoms occurs after initiating anti-tuberculous treatment. Treatment of pneumatoceles is usually conservative and surgical treatment should be used in patients with giant cysts which cause respiratory distress.Infection by SARS-CoV-2 has led to disease referred to as coronavirus disease 2019 which, in children has been described as of multisystem inflammatory syndrome in children. Our experience demonstrates 2 distinct presentations of this syndrome which have different clinical courses and may have differing long-term outcomes.The complement system is essential for protection against infections in oncologic patients because of the chemotherapy-induced immunosuppression. One of the key elements in the activation of the complement system via the lectin pathway is the appropriate functioning of mannose-binding lectin (MBL) and mannose-binding lectin-associated serine protease 2 (MASP2) complex. The objective of our study was to find an association between polymorphisms resulting in low MBL level and activation of the MBL-MASP2 complex. Also, we aimed at finding a connection between these abnormalities and the frequency and severity of febrile neutropenic episodes in children suffering from hemato-oncologic diseases. Ninety-seven patients had been enrolled and followed from the beginning of the therapy for 8 months, and several characteristics of febrile neutropenic episodes were recorded. Genotypes of 4 MBL2 polymorphisms (-221C/G, R52C, G54D, G57E) were determined by real-time polymerase chain reaction. Activation of the MBL-MASP2 complex was evaluated by enzyme-linked immunosorbent assay at the time of diagnosis and during an infection. The number of febrile neutropenic episodes was lower, and the time until the first episode was longer in patients with normal MBL level than in patients with low MBL level coding genotypes. The MBL-MASP2 complex activation level correlated with the MBL genotype and decreased significantly during infections in patients with low MBL level. Our results suggest that infections after immunosuppression therapy in children suffering from hemato-oncologic diseases are associated with the MBL2 genotype. Our results may contribute to the estimation of risk for infections in the future, which may modify therapeutic options for individuals.

Age-dependent differences in clinical presentation and viral loads in infants and young children with respiratory syncytial virus (RSV) infection, and their correlation with disease severity are poorly defined.

Previously healthy children <2 years old with mild (outpatients) and severe (inpatients) RSV infection were enrolled and viral loads measured by polymerase chain reaction in nasopharyngeal swabs. Patients were stratified by age in 0-<3, 3-6 and >6-24 months, and multivariable analyses were performed to identify clinical and viral factors associated with severe disease.

From 2014 to 2018, we enrolled 534 children with RSV infection, 130 outpatients with mild RSV infection and 404 inpatients with severe RSV disease. Median duration of illness was 4 days for both groups, yet viral loads were higher in outpatients than in inpatients (P < 0.001). In bivariate analyses, wheezing was more frequent in outpatients of older age (>3 months) than in inpatients (P < 0.01), while fever was more common in inpatients than outpatients (P < 0.01) and its frequency increased with age. Adjusted analyses confirmed that increased work of breathing and fever were consistently associated with hospitalization irrespective of age, while wheezing in infants >3 months, and higher RSV loads in children >6-24 months were independently associated with reduced disease severity.

Age had a significant impact defining the interactions among viral loads, specific clinical manifestations and disease severity in children with RSV infection. These observations highlight the importance of patient stratification when evaluating interventions against RSV.

Clinical knowledge of human adenovirus type 7 (HAdV-7) pneumonia in children remains limited. Moreover, predictors for disease severity are largely unknown.

This is a retrospective study of children hospitalized at Liuzhou Maternal and Child Health Hospital, China, with HAdV-7 pneumonia in 2018-2019. Demographics, clinical characteristics, laboratory results, and imaging data were collected. HAdV-7 was identified in plasma using whole genome sequencing, which yielded quantitative HAdV-7 sequence numbers.

There were 204 children; 145 (71%) were <2 years of age. There were 68 children with severe pneumonia (SP) and 136 with nonsevere pneumonia (NSP). Up to 43% in SP group with respiratory failure (SP-RF) were <12 months of age. Median duration of fever before hospitalization was shorter in NSP group than SP groups (P < 0.01). Fourteen (6.9%) underwent mechanical ventilation. There was a significant difference in mean plasma HAdV-7 sequence numbers among SP-RF, SP without respiratory failure (SP-NRF), and NSP groups (2485 ± 165, 2034 ± 124, and 286 ± 35, respectively) (P < 0.
