Meta-Analysis Review
Monkeypox (mpox) is a significant health concern affecting children and adolescents globally. This systematic review and meta-analysis aims to synthesise the available evidence on the proportion of children and adolescents affected by the mpox virus. A comprehensive search was conducted in seven electronic databases (PubMed, Scopus, Web of Science, EMBASE, ProQuest, EBSCOHost, and Cochrane) to identify the original reports on mpox cases in children and adolescents till 15 January 2023. Descriptive reports on probable or laboratory-confirmed mpox in children and adolescents (0-17 years old) were considered eligible. Studies not providing separate data for the above age group and case-control studies were excluded. The primary outcome was pooled proportion of mpox cases among children and adolescents. Proportion meta-analysis and heterogeneity between studies were determined using a restricted maximum likelihood estimator, and a random-effects model was fitted to the data. Sensitivity analysis and subgroup analysis were also conducted. A drapery plot was also provided as a complementary figure to the forest plot. The protocol was prospectively registered with PROSPERO (CRD42023392475). A total of 440 studies were identified, of which 37 were included in the review and 25 in the meta-analysis (62,701 participants with 3306 children and adolescents). The pooled proportion of children and adolescents was 0.46 (95% CI: 0.30-0.63, I :100%). The proportion of children and adolescents was significantly lower (p < 0.001) in the ongoing pandemic 0.04 (95% CI: 0.00-0.32) than before 2022 0.62 (95% CI: 0.49-0.74). The meta-regression showed that the higher the study's sample size, the lower the proportion of children among the mpox cases. Both overall and subgroup heterogeneity were high. Adolescents and children below 5 years are commonly affected by the ongoing pandemic. In conclusion, the high proportion of children affected by the mpox virus highlights the need for increased research and targeted interventions to prevent and control the spread of the virus in this population.

Meta-Analysis
PURPOSE
MPOX has numerous otolaryngologic presentations that have been recognized as clinically important, especially with the onset of the 2022 outbreak. However, how these features vary across region and outbreak have yet to be elucidated or supported by meta-analysis. The objective of this study is to identify the otolaryngologic manifestations of MPOX across previous and current outbreaks and among endemic and non-endemic regions.
BASIC PROCEDURES
Data sources of MEDLINE (PubMed), the Cochrane Library, Scopus, Embase, Web of Science, Google Scholar, and OpenGrey were searched through August 2022. All observational studies reporting data on laboratory-confirmed MPOX patients with otolaryngologic symptoms were included. Two authors independently performed the screening process while a third resolved disagreements. Data were extracted into a structured form by two authors independently. We performed a meta-analysis of the prevalence of otorhinolaryngologic symptoms using MetaXL software (version 5.3) under a random-effects model.
MAIN FINDINGS
38 studies with 5952 patients were included. The four most prevalent manifestations were headache at 31 % (95 % CI [0.16-0.49], I = 99 %), sore throat at 22 % (95 % CI [0.09-0.37], I = 99 %), cough at 16 % (95 % CI [0.05-0.30], I = 99 %), and cervical lymphadenopathy at 10 % (95 % CI [0.01-0.26], I = 100 %). Otolaryngologic features were more prevalent in previous outbreaks as compared to the 2022 outbreak including 37 % prevalence of headache (95 % CI [0.11-0.66], I = 100 %), 33 % prevalence of cough (95 % CI [0.21-0.47], I = 98 %), 27 % prevalence of sore throat (95 % CI [0.07-0.53], I = 99 %), 15 % prevalence of cervical lymphadenopathy (95 % CI [0.00-0.428], I = 100 %), 13 % prevalence of oral ulcers (95 % CI [0.02-0.30], I = 99 %), 6 % prevalence of oral exanthem (95 % CI [0.00-0.17], I = 99 %), 5 % prevalence of dysphagia (95 % CI [0.00-0.18], I = 99 %), and 5 % prevalence of tonsillar signs (95 % CI [0.00-0.13], I = 99 %). Features that were more prevalent in endemic areas versus non-endemic areas include 27 % prevalence of cough (95 % CI [0.14-0.41], I = 99 %), 15 % prevalence of oral ulcers (95 % CI [0.02-0.36], I = 99 %), 6 % prevalence of tonsillar signs (95 % CI [0.00-0.18], I = 99 %), and 19 % prevalence of cervical lymphadenopathy (95 % CI [0.00-0.48], I = 100 %), while the only feature more prevalent in non-endemic areas was headache with a prevalence of 36 % (95 % CI [0.24-0.47], I = 96 %).
PRINCIPAL CONCLUSIONS
In this systematic review and meta-analysis, four symptoms - headache, sore throat, cough, and cervical lymphadenopathy - were found to be the most prevalent otolaryngologic features of MPOX. Otolaryngologic manifestations of MPOX were more pronounced in prior outbreaks and in endemic areas as compared to the 2022 outbreak and non-endemic areas. These findings may aid MPOX recognition in an otolaryngology setting.

Meta-Analysis
BACKGROUND
Human monkeypox (mpox) disease is a multicountry outbreak driven by human-human transmission which has resulted in an international public health emergency. However, there is limited evidence on the positivity rate of skin lesions for mpox viral DNA. We aim to fill this gap by estimating the pooled positivity rate of skin samples with mpox viral DNA from mpox patients globally.
METHODS
In this systematic review and meta-analysis, seven databases and several preprint servers have been extensively searched until 17 January 2023 according to a prospectively registered protocol (PROSPERO: CRD42023392505). Articles including the positivity rate of skin samples with mpox viral DNA in mpox-confirmed patients were considered eligible. After a quality assessment, a random-effect meta-analysis was used for pooled prevalence. To explore and resolve heterogeneity, we used statistical methods for outlier detection, influence analysis, and sensitivity analysis.
FINDINGS
Among the 331 articles retrieved after deduplication, 14 studies were finally included. The pooled positivity rate of the skin samples was 98.77% (95% CI: 94.74%-99.72%). After the removal of an influential outlier, for heterogeneity dropped from 92.5% to 10.8%. Meta-regression did not reveal any significant moderator.
CONCLUSION/INTERPRETATION
The present findings reinforce that skin lesions act as a reservoir of mpox viral DNA and contribute to a high infectivity risk. This may be a prevailing basis of prompt transmission during the current multicountry outbreak and also needs further investigation. The present imperative outcome may benefit in producing valuable preventive and management procedures in an appropriate health strategy.

BACKGROUND
There is an increasing number of cases being reported of neurological manifestations of Coronavirus disease 2019 (COVID-19) infection and Monkeypox (Mpox), both during the course of the infection and as a presenting symptom. We aim to review the neurological manifestations of COVID-19 and monkeypox in pediatric patients and their management.
METHODS
We conducted a systematic review that included cohort studies and case series or reports involving a pediatric population of patients with a confirmed COVID-19 or Mpox infection and their neurological manifestations. We searched the following electronic databases: PubMed, EMBASE, and Scopus.
RESULTS
From 1136 articles identified, 127 studies were included. Headache, stroke, Guillain-Barré syndrome, seizure, nerve palsies, and multisystem inflammatory syndrome in children were the most common neurological symptoms caused by COVID-19, whereas encephalitis was commonly seen in patients with Mpox. Rare neurological manifestations of COVID-19 included cerebral venous sinus thrombosis, plexopathies, demyelinating disorders, encephalitis, etc., and rare neurological manifestations of Mpox included headache.
CONCLUSIONS
Our review highlights the importance of investigating possible neurological manifestations and closely monitoring these patients to develop a better understanding of the treatment strategies that can be adopted.

PURPOSE OF REVIEW
The risk of nosocomial transmission of mpox during the 2022 global outbreak is not well described. We evaluated reports of exposures to healthcare personnel (HCP) and patients in healthcare settings and risk of transmission.
RECENT FINDINGS
Reported nosocomial transmission of mpox has been rare and associated primarily with sharps injuries and breaches in transmission-based precautions.
SUMMARY
Currently recommended infection control practices, including the use of standard and transmission-based precautions in the care of patients with known or suspected mpox are highly effective. Diagnostic sampling should not involve the use of needles or other sharp instruments.

Review
Since May 2022, there has been a global increase in the number of Mpox virus (MPXV) cases in countries that were previously considered non-endemic. In July 2022, the World Health Organization (WHO) declared this outbreak a public health emergency of international concern. The objective of this systematic review is to examine the novel clinical features of Mpox and to assess the available treatment options for managing the disease in patients who are afflicted with it. We conducted a systematic search in several databases, including PubMed, Google Scholar, Cochrane Library, and the grey literature, from May 2022 to February 2023. We identified 21 eligible studies, which included 18,275 Mpox cases, for final qualitative analysis. The majority of cases were reported in men who have sex with men (MSM) and immunocompromised individuals with HIV (36.1%). The median incubation period was 7 days (IQR: 3-21). The novel clinical manifestations include severe skin lesions on the palms, oral and anogenital regions, as well as proctitis, penile edema, tonsillitis, ocular disease, myalgia, lethargy, and sore throat, without any preceding prodromal symptoms or systemic illness. In addition, fully asymptomatic cases were documented, and various complications, including encephalomyelitis and angina, were noted. Clinicians must be familiar with these novel clinical characteristics, as they can aid in testing and tracing such patients, as well as asymptomatic high-risk populations such as heterosexuals and MSM. In addition to supportive care, currently, there are several effective prophylactic and treatment strategies available to combat Mpox, including the vaccines ACAM2000 and MVA-BN7, as well as the immunoglobulin VIGIV and the antivirals tecovirimat, brincidofovir, and cidofovir against severe Mpox infection.

BACKGROUND
Monkeypox is a zoonotic viral infection first reported in May 2022. Monkeypox cases present with prodromal symptoms, rash, and/or systemic complications. This study systematically reviews the monkeypox cases presented with any cardiac complications.
METHODS
A systematic literature search was done to locate papers that discuss any cardiac complications associated with monkeypox; then, data were analyzed qualitatively.
RESULTS
Nine articles, including the 13 cases that reported cardiac complications of the disease, were included in the review. Five cases previously had sex with men, and two cases had unprotected intercourse, which reveals the importance of the sexual route in disease transmission. All cases have a wide spectrum of cardiac complications, such as acute myocarditis, pericarditis, pericardial effusion, and myopericarditis.
CONCLUSION
This study clarifies the potential for cardiac complications in monkeypox cases and provides avenues for future research to determine the underlying mechanism. Also, we found that the cases with pericarditis were treated with colchicine, and those with myocarditis were treated with supportive care or cardioprotective treatment (Bisoprolol and Ramipril). Furthermore, Tecovirimat is used as an antiviral drug for 14 days.

Meta-Analysis Review
Despite monkeypox (mpox) being a public health emergency, there is limited knowledge about the risk of infectivity from skin viral loads during mpox infection. Thus, the aim of this study was to estimate cutaneous viral loads among mpox patients globally. Several databases, including Cochrane, EBSCOHost, EMBASE, ProQuest, PubMed, Scopus, and Web of Science, and preprint servers were searched concerning skin mpox viral loads in confirmed mpox subjects. In this systematic review and meta-analysis, a total of 331 articles were initially screened after the removal of duplicate entries. A total of nine articles were included in the systematic review and meta-analysis for the overall estimation of viral loads (Ct) using a random-effect model. The pooled cutaneous mpox viral load (lower Ct) was 21.71 (95% CI: 20.68-22.75) with a majority of positivity rates being 100%, highlighting a higher infectivity risk from skin lesions. The current results strongly support that skin mpox viral loads may be a dominant source of rapid transmission during current multi-national outbreaks. This important finding can help in constructing useful measures in relevant health policy.

Meta-Analysis
PURPOSE
The purpose of this study was to pool the prevalence rate of monkeypox-associated eye manifestations and/or complications during the current and previous outbreaks.
DESIGN
A systematic review and meta-analysis.
MATERIALS AND METHODS
On August 7, 2022, PubMed, Scopus, Web of Science, EMBASE, and Google Scholar were searched for relevant articles. We included all studies that reported the involvement of the eye (either as a manifestation or a complication) among patients with monkeypox. The primary outcome included pooling the effect size (ES) of reported manifestations and complications, and the secondary outcome included the conduct of a subgroup analysis based on the timing of the monkeypox outbreak (before vs. during 2022).
RESULTS
Eleven studies reporting 3179 monkeypox-confirmed cases were included. Eye manifestations included conjunctivitis, corneal, conjunctival, and eyelid lesions, photophobia, and eye pain. Compared with previous monkeypox outbreaks, the current outbreak revealed much lower rates of ocular involvement in terms of conjunctivitis (ES=1%; 95% CI: 0%-1% vs. ES=17%; 95% CI: 11%-22%), corneal and conjunctival lesions (ES=1%; 95% CI: 0%-2% vs. ES=13%; 95% CI: 4%-22%), and eyelid lesions (ES=1%; 95% CI: 0%-4% vs. ES=13%; 95% CI: 5%-28%). Monkeypox-associated eye complications were reported only in the previous outbreaks which included keratitis (ES=4%; 95% CI: 3%-6%), corneal ulceration (ES=4%; 95% CI: 2%-5%), unilateral (ES=3%; 95% CI: 1%-4%) and bilateral blindness (ES=0%; 95% CI: 0%-2%), and impaired vision (ES=4%; 95% CI: 1%-8%).
CONCLUSIONS
Ophthalmic manifestations and complications are common among monkeypox-confirmed cases. Although these data are mainly related to previous outbreaks, health care workers should familiarize themselves with these signs to provide better care for monkeypox patients.

Review
The recent multi-country outbreak of Mpox (Monkeypox disease) constituted a public health emergency. Although animal-to-human transmission is known to be the primary way of transmission, an increasing number of cases transmitted by person-to-person contact have been reported. During the recent Mpox outbreak sexual or intimate contact has been considered the most important way of transmission. However, other routes of transmission must not be ignored. The knowledge of how the Monkeypox Virus (MPXV) spreads is crucial to implement adequate measures to contain the spread of the disease. Therefore, this systematic review aimed to collect scientific data published concerning other implicated sources of infection beyond sexual interaction, such as the involvement of respiratory particles, contact with contaminated surfaces and skin-to-skin contact. The current study was performed using the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Publications analyzing contacts of Mpox index cases and their outcome after contact were included. A total of 7319 person-to-person contacts were surveyed and 273 of them became positive cases. Positive secondary transmission of MPXV was verified after contact with people cohabiting in the same household, with family members, with healthcare workers, or within healthcare facilities, and sexual contact or contact with contaminated surfaces. Using the same cup, sharing the same dishes, and sleeping in the same room or bed were also positively associated with transmission. Five studies showed no evidence of transmission despite contact with surfaces, skin-to-skin contact, or through airway particles within healthcare facilities where containment measures were taken. These records support the case for person-to-person transmission and suggest that other types of contact beyond sexual contact pose a significant risk of acquiring the infection. Further investigation is crucial to elucidate MPXV transmission dynamics, and to implement adequate measures to contain the spread of the infection.
