RESUMO
OBJECTIVE: To evaluate neuromotor repertoires and developmental milestones in infants exposed to antenatal COVID-19. DESIGN: Longitudinal cohort study. SETTING: Hospital-based study in Los Angeles, USA and Rio de Janeiro, Brazil between March 2020 and December 2021. PARTICIPANTS: Infants born to mothers with COVID-19 during pregnancy and prepandemic control infants from the Graz University Database. INTERVENTIONS: General movement assessment (GMA) videos between 3 and 5 months post-term age were collected and clinical assessments/developmental milestones evaluated at 6-8 months of age. Cases were matched by gestational age, gender and post-term age to prepandemic neurotypical unexposed controls from the database. MAIN OUTCOME MEASURES: Motor Optimality Scores Revised (MOS-R) at 3-5 months. Presence of developmental delay (DD) at 6-8 months. RESULTS: 239 infants were enrolled; 124 cases (83 in the USA/41 in Brazil) and 115 controls. GMA was assessed in 115 cases and 115 controls; 25% were preterm. Median MOS-R in cases was 23 (IQR 21-24, range 9-28) vs 25 (IQR 24-26, range 20-28) in controls, p<0.001. Sixteen infants (14%) had MOS-R scores <20 vs zero controls, p<0.001. At 6-8 months, 13 of 109 case infants (12%) failed to attain developmental milestones; all 115 control infants had normal development. The timing of maternal infection in pregnancy (first, second or third trimester) or COVID-19 disease severity (NIH categories asymptomatic, mild/moderate or severe/critical) was not associated with suboptimal MOS-R or DD. Maternal fever in pregnancy was associated with DD (OR 3.7; 95% CI 1.12 to 12.60) but not suboptimal MOS-R (OR 0.25; 95% CI 0.04 to 0.96). CONCLUSIONS: Compared with prepandemic controls, infants exposed to antenatal COVID-19 more frequently had suboptimal neuromotor development.

OBJECTIVE: To assess the comparative effectiveness and ranking of minimally invasive treatments (MITs) for lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: We searched multiple databases up to 24 February 2021. We included randomized controlled trials assessing the following treatments: convective radiofrequency water vapour thermal therapy (WVTT; or Rezum); prostatic arterial embolization (PAE); prostatic urethral lift (PUL; or Urolift); temporary implantable nitinol device (TIND); and transurethral microwave thermotherapy (TUMT) compared to transurethral resection of the prostate (TURP) or sham surgery. We performed a frequentist network meta-analysis. RESULTS: We included 27 trials involving 3017 men. The overall certainty of the evidence of most outcomes according to GRADE was low to very low. Compared to TURP, we found that PUL and PAE may result in little to no difference in urological symptoms, while WVTT, TUMT and TIND may result in worse urological symptoms. MITs may result in little to no difference in quality of life, compared to TURP. MITs may result in a large reduction in major adverse events compared to TURP. We were uncertain about the effects of PAE and PUL on retreatment compared to TURP, however, TUMT may result in higher retreatment rates. We were very uncertain of the effects of MITs on erectile function and ejaculatory function. Among MITs, PUL and PAE had the highest likelihood of being the most efficacious for urinary symptoms and quality of life, TUMT for major adverse events, WVTT and TIND for erectile function and PUL for ejaculatory function. Excluding WVTT and TIND, for which there were only studies with short-term (3-month) follow-up, PUL had the highest likelihood of being the most efficacious for retreatment. CONCLUSIONS: Minimally invasive treatments may result in similar or worse effects concerning urinary symptoms and quality of life compared to TURP at short-term follow-up.

BACKGROUND: A variety of minimally invasive treatments are available as an alternative to transurethral resection of the prostate (TURP) for management of lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). However, it is unclear which treatments provide better results. OBJECTIVES: Our primary objective was to assess the comparative effectiveness of minimally invasive treatments for lower urinary tract symptoms in men with BPH through a network meta-analysis. Our secondary objective was to obtain an estimate of relative ranking of these minimally invasive treatments, according to their effects. SEARCH METHODS: We performed a comprehensive search of multiple databases (CENTRAL, MEDLINE, Embase, Scopus, Web of Science and LILACS), trials registries, other sources of grey literature, and conference proceedings, up to 24 February 2021. We had no restrictions on language of publication or publication status. SELECTION CRITERIA: We included parallel-group randomized controlled trials assessing the effects of the following minimally invasive treatments, compared to TURP or sham treatment, on men with moderate to severe LUTS due to BPH: convective radiofrequency water vapor therapy (CRFWVT); prostatic arterial embolization (PAE); prostatic urethral lift (PUL); temporary implantable nitinol device (TIND); and transurethral microwave thermotherapy (TUMT). DATA COLLECTION AND ANALYSIS: Two review authors independently screened the literature, extracted data, and assessed risk of bias. We performed statistical analyses using a random-effects model for pair-wise comparisons and a frequentist network meta-analysis for combined estimates. We interpreted them according to Cochrane methods. We planned subgroup analyses by age, prostate volume, and severity of baseline symptoms. We used risk ratios (RRs) with 95% confidence intervals (CIs) to express dichotomous data and mean differences (MDs) with 95% CIs to express continuous data. We used the GRADE approach to rate the certainty of evidence. MAIN RESULTS: We included 27 trials involving 3017 men, mostly over age 50, with severe LUTS due to BPH. The overall certainty of evidence was low to very low due to concerns regarding bias, imprecision, inconsistency (heterogeneity), and incoherence. Based on the network meta-analysis, results for our main outcomes were as follows. Urologic symptoms (19 studies, 1847 participants): PUL and PAE may result in little to no difference in urologic symptoms scores (MD of International Prostate Symptoms Score [IPSS]) compared to TURP (3 to 12 months; MD range 0 to 35; higher scores indicate worse symptoms; PUL: 1.47, 95% CI -4.00 to 6.93; PAE: 1.55, 95% CI -1.23 to 4.33; low-certainty evidence). CRFWVT, TUMT, and TIND may result in worse urologic symptoms scores compared to TURP at short-term follow-up, but the CIs include little to no difference (CRFWVT: 3.6, 95% CI -4.25 to 11.46; TUMT: 3.98, 95% CI 0.85 to 7.10; TIND: 7.5, 95% CI -0.68 to 15.69; low-certainty evidence). Quality of life (QoL) (13 studies, 1459 participants): All interventions may result in little to no difference in the QoL scores, compared to TURP (3 to 12 months; MD of IPSS-QoL score; MD range 0 to 6; higher scores indicate worse symptoms; PUL: 0.06, 95% CI -1.17 to 1.30; PAE: 0.09, 95% CI -0.57 to 0.75; CRFWVT: 0.37, 95% CI -1.45 to 2.20; TUMT: 0.65, 95% CI -0.48 to 1.78; TIND: 0.87, 95% CI -1.04 to 2.79; low-certainty evidence). Major adverse events (15 studies, 1573 participants): TUMT probably results in a large reduction of major adverse events compared to TURP (RR 0.20, 95% CI 0.09 to 0.43; moderate-certainty evidence). PUL, CRFWVT, TIND and PAE may also result in a large reduction in major adverse events, but CIs include substantial benefits and harms at three months to 36 months; PUL: RR 0.30, 95% CI 0.04 to 2.22; CRFWVT: RR 0.37, 95% CI 0.01 to 18.62; TIND: RR 0.52, 95% CI 0.01 to 24.46; PAE: RR 0.65, 95% CI 0.25 to 1.68; low-certainty evidence). Retreatment (10 studies, 799 participants): We are uncertain about the effects of PAE and PUL on retreatment compared to TURP (12 to 60 months; PUL: RR 2.39, 95% CI 0.51 to 11.1; PAE: RR 4.39, 95% CI 1.25 to 15.44; very low-certainty evidence). TUMT may result in higher retreatment rates (RR 9.71, 95% CI 2.35 to 40.13; low-certainty evidence). Erectile function (six studies, 640 participants): We are very uncertain of the effects of minimally invasive treatments on erectile function (MD of International Index of Erectile Function [IIEF-5]; range 5 to 25; higher scores indicates better function; CRFWVT: 6.49, 95% CI -8.13 to 21.12; TIND: 5.19, 95% CI -9.36 to 19.74; PUL: 3.00, 95% CI -5.45 to 11.44; PAE: -0.03, 95% CI -6.38, 6.32; very low-certainty evidence). Ejaculatory dysfunction (eight studies, 461 participants): We are uncertain of the effects of PUL, PAE and TUMT on ejaculatory dysfunction compared to TURP (3 to 12 months; PUL: RR 0.05, 95 % CI 0.00 to 1.06; PAE: RR 0.35, 95% CI 0.13 to 0.92; TUMT: RR 0.34, 95% CI 0.17 to 0.68; low-certainty evidence). TURP is the reference treatment with the highest likelihood of being the most efficacious for urinary symptoms, QoL and retreatment, but the least favorable in terms of major adverse events, erectile function and ejaculatory function. Among minimally invasive procedures, PUL and PAE have the highest likelihood of being the most efficacious for urinary symptoms and QoL, TUMT for major adverse events, PUL for retreatment, CRFWVT and TIND for erectile function and PUL for ejaculatory function. AUTHORS' CONCLUSIONS: Minimally invasive treatments may result in similar or worse effects concerning urinary symptoms and QoL compared to TURP at short-term follow-up. They may result in fewer major adverse events, especially in the case of PUL and PAE; resulting in better rankings for symptoms scores. PUL may result in fewer retreatments compared to other interventions, especially TUMT, which had the highest retreatment rates at long-term follow-up. We are very uncertain about the effects of these interventions on erectile function. There was limited long-term data, especially for CRFWVT and TIND. Future high-quality studies with more extended follow-up, comparing different, active treatment modalities, and adequately reporting critical outcomes relevant to patients, including those related to sexual function, could provide more information on the relative effectiveness of these interventions.

PURPOSE: To assess the effects of Serenoa repens alone or in combination with other phytotherapy compared to placebo in men with LUTS due to benign prostatic enlargement. MATERIALS AND METHODS: Following a registered protocol (CRD42021226655), we searched (December 2020) MEDLINE, CENTRAL, Embase, ClinicalTrials.gov, WHO-ICTRP trials platform and other sources with no restrictions on language, publication date or status. We included randomized controlled trials, and we critically appraised them using the Cochrane Tool for Risk of Bias Assessment (RoB 2). We conducted random-effects meta-analysis when appropriate. The primary outcomes included urinary symptoms score, quality of life, and adverse events. The certainty of the evidence was rated using GRADE. RESULTS: We included 27 trials with 4,853 participants. S. repens results in little to no difference in urinary symptoms, quality of life, and adverse events at short- and long-term follow-up. S. repens combined with other phytotherapy may slightly reduce urinary symptoms at short-term follow-up, but the results are uncertain. The results on quality of life and adverse events are also very uncertain. CONCLUSIONS: S. repens alone may result in no clinical benefits for men with LUTS. There is greater uncertainty in the effects of S. repens in combination with other phytotherapy.

We report Zika virus (ZIKV) vertical transmission in 130 infants born to PCR+ mothers at the time of the Rio de Janeiro epidemic of 2015-2016. Serum and urine collected from birth through the first year of life were tested by quantitative reverse transcriptase polymerase chain reaction (PCR) and/or IgM Zika MAC-ELISA. Four hundred and seven specimens are evaluated; 161 sera tested by PCR and IgM assays, 85 urines by PCR. Sixty-five percent of children (N = 84) are positive in at least one assay. Of 94 children tested within 3 months of age, 70% are positive. Positivity declines to 33% after 3 months. Five children are PCR+ beyond 200 days of life. Concordance between IgM and PCR results is 52%, sensitivity 65%, specificity 40% (positive PCR results as gold standard). IgM and serum PCR are 61% concordant; serum and urine PCR 55%. Most children (65%) are clinically normal. Equal numbers of children with abnormal findings (29 of 45, 64%) and normal findings (55 of 85, 65%) have positive results, p = 0.98. Earlier maternal trimester of infection is associated with positive results (p = 0.04) but not clinical disease (p = 0.98). ZIKV vertical transmission is frequent but laboratory confirmed infection is not necessarily associated with infant abnormalities.

OBJECTIVE: To assess the effects of pharmacological therapies for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). PATIENTS AND METHODS: We performed a comprehensive search using multiple databases, trial registries, grey literature and conference proceedings with no restrictions on the language of publication or publication status. The date of the latest search of all databases was July 2019. We included randomised controlled trials. Inclusion criteria were men with a diagnosis of CP/CPPS. We included all available pharmacological interventions. Two review authors independently classified studies and abstracted data from the included studies, performed statistical analyses and rated quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. The primary outcomes were prostatitis symptoms and adverse events. The secondary outcomes were sexual dysfunction, urinary symptoms, quality of life, anxiety and depression. RESULTS: We included 99 unique studies in 9119 men with CP/CPPS, with assessments of 16 types of pharmacological interventions. Most of our comparisons included short-term follow-up information. The median age of the participants was 38 years. Most studies did not specify their funding sources; 21 studies reported funding from pharmaceutical companies. We found low- to very low-quality evidence that α-blockers may reduce prostatitis symptoms based on a reduction in National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) scores of >2 (but <8) with an increased incidence of minor adverse events such as dizziness and hypotension. Moderate- to low-quality evidence indicates that 5α-reductase inhibitors, antibiotics, anti-inflammatories, and phytotherapy probably cause a small decrease in prostatitis symptoms and may not be associated with a greater incidence of adverse events. Intraprostatic botulinum toxin A (BTA) injection may cause a large reduction in prostatitis symptoms with procedure-related adverse events (haematuria), but pelvic floor muscle BTA injection may not have the same effects (low-quality evidence). Allopurinol may also be ineffective for reducing prostatitis symptoms (low-quality evidence). We assessed a wide range of interventions involving traditional Chinese medicine; low-quality evidence showed they may reduce prostatitis symptoms without an increased incidence in adverse events. Moderate- to high-quality evidence indicates that the following interventions may be ineffective for the reduction of prostatitis symptoms: anticholinergics, Escherichia coli lysate (OM-89), pentosan, and pregabalin. Low- to very low-quality evidence indicates that antidepressants and tanezumab may be ineffective for the reduction of prostatitis symptoms. Low-quality evidence indicates that mepartricin and phosphodiesterase inhibitors may reduce prostatitis symptoms, without an increased incidence in adverse events. CONCLUSIONS: Based on the findings of low- to very low-quality evidence, this review found that some pharmacological interventions such as α-blockers may reduce prostatitis symptoms with an increased incidence of minor adverse events such as dizziness and hypotension. Other interventions may cause a reduction in prostatitis symptoms without an increased incidence of adverse events while others were found to be ineffective.

Importance: Congenital Zika virus (ZIKV) infection may present with a spectrum of clinical and neuroradiographic findings. Objective: To determine whether neuroimaging findings for infants with a history of ZIKV exposure are associated with infant clinical outcomes and gestational age at antenatal ZIKV infection. Design, Setting, and Participants: This cohort study retrospectively reviewed neuroimaging results (computed tomography and/or magnetic resonance imaging scans) of 110 ZIKV-exposed infants from a maternity and children's hospital in Rio de Janeiro, Brazil, following the 2015 to 2016 ZIKV epidemic. Neuroimaging from March 1, 2016, to June 30, 2017, was evaluated to determine whether findings were associated with clinical outcomes and the timing of maternal ZIKV infection. Data were analyzed from July 1, 2017, to August 30, 2018. Exposures: Neuroimaging (computed tomography and/or magnetic resonance imaging) was performed on ZIKV-exposed infants after birth. Blood and/or urine specimens from mothers and infants were tested for ZIKV by polymerase chain reaction assay. Main Outcomes and Measures: Neuroimaging studies were evaluated for structural abnormalities and other forms of brain injury. Results: A total of 110 infants with a mean (SD) gestational age of 38.4 (2.1) weeks had neuroimaging and clinical outcome data reviewed. Of these, 71 (65%) had abnormal neuroimaging findings, with the majority (96%) classified as having severe ZIKV infection at birth. The most common neuroimaging abnormalities were structural abnormalities including brain calcifications, especially at the cortico-subcortical white matter junction, cortex malformations, ventriculomegaly, and reduced brain volumes, followed by brainstem hypoplasia, cerebellar hypoplasia, and corpus callosum abnormalities. Frequency of abnormal imaging was higher in infants with specific clinical findings as opposed to those without them; these findings included fetal brain disruption sequence (100% vs 35%), microcephaly (100% vs 30%), congenital contractures (100% vs 58%), ophthalmologic abnormalities (95% vs 44%), hearing abnormalities (100% vs 58%), and neurologic symptoms (94% vs 10%). Four of 39 infants (10%) without initial evidence of severe ZIKV infection and normal findings on neurologic evaluation at birth had abnormal neuroimaging findings. Neuroimaging abnormalities differed by trimester of maternal ZIKV infection, with 63% of infants born to mothers infected in the first trimester, 13% of infants born to mothers infected in the second trimester, and 1% of infants born to mothers infected in the third trimester exhibiting neuroimaging abnormalities. The odds of abnormal neuroimaging were 7.9 times greater for infants with first trimester ZIKV exposure compared with other trimesters combined (odds ratio, 7.9; 95% CI, 3.0-20.4; P < .001). Conclusions and Relevance: Neuroimaging abnormalities of computed tomography and/or magnetic resonance imaging scans were common in ZIKV-exposed infants. While neuroimaging abnormalities were seen in 10% of infants without clinically severe ZIKV, most occurred almost exclusively among those with clinically severe ZIKV, especially among those with a history of ZIKV exposure in the first trimester.

OBJECTIVE: To assess the effects of non-pharmacological therapies for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). PATIENTS AND METHODS: We performed a comprehensive search using multiple databases, trial registries, grey literature and conference proceedings with no restrictions on the language of publication or publication status. The date of the latest search of all databases was August 2017. We included randomized controlled trials in men with a diagnosis of CP/CPPS. We included all available non-pharmacological interventions. Two review authors independently classified studies and abstracted data from the included studies, performed statistical analyses and rated quality of evidence (QoE) according to the Grading of Recommendations Assessment, Development and Evaluation methods. The primary outcomes were prostatitis symptoms and adverse events. The secondary outcomes were sexual dysfunction, urinary symptoms, quality of life, anxiety and depression. RESULTS: We included 38 unique studies in 3290 men with CP/CPPS across 23 comparisons, reporting outcomes mostly at short-term follow-up. Our analysis showed that acupuncture probably leads to clinically meaningful reduction in prostatitis symptoms compared with a sham procedure (mean difference [MD] in total National Institutes of Health - Chronic Prostatitis Symptom Index [NIH-CPSI] score -5.79, 95% confidence interval [CI] -7.32 to -4.26, moderate QoE). Acupuncture may result in little or no difference in adverse events (low QoE). Acupuncture may also lead to a clinically meaningful reduction in prostatitis symptoms compared with standard medical therapy (MD -6.05, 95% CI -7.87 to -4.24, two studies, 78 participants, low QoE). Lifestyle modifications may be associated with a reduction in prostatitis symptoms compared with control (risk ratio for improvement in NIH-CPSI scores 3.90, 95% CI 2.20 to 6.92, very low QoE), but we found no information regarding adverse events. A physical activity programme may cause a small reduction in prostatitis symptoms compared with control (NIH-CPSI score MD -2.50, 95% CI -4.69 to -0.31, low QoE), but we found no information regarding adverse events. It was uncertain whether prostatic massage reduces or increases prostatitis symptoms compared with control (very low QoE) and we found no information regarding adverse events. Extracorporeal shockwave therapy reduces prostatitis symptoms compared with control (NIH-CPSI score MD -6.18, 95% CI -7.46 to -4.89, high QoE), but these results may not be sustained at medium-term follow-up (low QoE). This treatment may not be associated with a greater incidence of adverse events (low QoE). Transrectal thermotherapy, alone or in combination with medical therapy, may decrease prostatitis symptoms slightly when compared with medical therapy alone (NIH-CPSI score MD -2.50, 95% CI -3.82 to -1.18, low QoE). One included study reported that participants may experience transient adverse events. CONCLUSIONS: Based on the findings with moderate to high QoE, this review found that some non-pharmacological interventions, such as acupuncture and extracorporeal shockwave therapy, are likely to result in a decrease in prostatitis symptoms and may not be associated with a greater incidence of adverse events. The QoE for most other comparisons was predominantly low. Future clinical trials should include a full report of their methods, including adequate masking, consistent assessment of all patient-important outcomes including potential treatment-related adverse events and appropriate sample sizes.

Abstract Background: Rheumatoid arthritis (RA) is known to be associated with coronary artery diseases (CAD). Previous studies of the association between RA and CAD were reported mainly in non-Asian groups. We aimed to examine the prevalence of RA and the relationship between RA and CAD in South Korea. Methods: We conducted a nationwide cross-sectional study by using the Korea National Health and Nutrition Examination Survey, which collected data for four years between 2008 and 2012. A total of 25,828 eligible participants were included. To balance the distribution of baseline characteristics, we used propensity scorematching. A multivariable logistic regression model was employed and we calculated the odds ratios (ORs) and 95% confidence intervals (CI) for the odds of the participants with RA on CAD prevalence. Results: The prevalence of RA in Korea from 2008 to 2012 was 0.6% and RA was predominant among elderly women. The prevalence of CAD in patients with RA was significantly higher than in general population. After propensity score-matching to balance the confounding factors, RA was significantly associated with CAD (OR 2.97, 95% CI 1.15-7.68, P= 0.02). Conclusions: The prevalence of RA in South Korea was comparable to the worldwide data, and the presence of CAD in RA patients was more than two-fold.

BACKGROUND: An intricate fetal-maternal immune crosstalk during pregnancy is essential for a healthy birth. Hence, the infection-induced alterations of maternal immunity often lead to adverse outcomes for mother and/or child. The emergence of Zika virus (ZIKV) infection in pregnant women has been associated with more than 3,000 cases of microcephaly and nervous system malformations. METHODS: To explore the potential correlation of ZIKV-induced alteration of maternal immunity with fetal abnormalities, we performed extensive sera immunoprofiling of 74 pregnant women: 30 symptomatic ZIKV+ pregnant patients and 30 healthy pregnant controls in ZIKV-endemic Rio de Janeiro, along with 14 healthy pregnant controls in non-endemic Los Angeles. RESULTS: Extensive multiplexing analysis of 69 cytokines revealed that CXCL10, CCL2, and CCL8 chemokines were specifically associated with symptomatic ZIKV+ infection during pregnancy, and distinct immunoprofiles were detected at different trimesters in ZIKV-infected pregnant women. Intriguingly, the high CCL2 level and its inverse correlation with CD163, TNFRSF1A, and CCL22 levels was apparently associated with ZIKV-induced abnormal birth. CONCLUSION: Our findings provide insights into the alteration of ZIKV-elicited maternal immunity, serving as a potential clinical biomarker platform.

Kaposi's sarcoma-associated herpesvirus (KSHV) is detected consistently in Kaposi's sarcoma (KS). Because of its dramatic sequence variation, the K1 gene has been used to classify KSHV. We found a diverse array of KSHV subtypes A1, A2, A3, A5, B1, B2, and C3 in 23 Cuban KS samples containing several novel sporadic insertions/deletions in subtypes A and C. The molecular epidemiology of the KSHV subtypes seems to reflect the unique mixed ethnic background of the Cuban population.
