Epidemiological data suggest 9-15% of ankle joint osteoarthritis (AOA) in the general population. One of the methods of delaying radical intervention is ankle joint distraction arthroplasty of the ankle joint (ADA), including a combination of various techniques. The lack of publications summarizing the maximum possible clinical data on ADA for more than 50 years of the method's history justifies the need for a review. A systematic review of ankle distraction arthroplasty followed the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) protocol guidelines. The inclusion criteria were articles with clinical data in full text in English, available on the Internet for the maximum possible period, including the treatment of diseases of the ankle joint using distraction arthroplasty. At the search stage, 4640 publications from 3 sources were identified. 33 articles were selected for analysis of the full texts of the articles. Additionally, 1 article was excluded, as it contains duplicate information from an identical study. The analysis of the full texts of 32 publications was made, according to the parameters indicated earlier. A total of 927 patients underwent ADA. The mean age of the patients was 44.9 ± 12.7 years. Among the causes, post-traumatic AOA was indicated in 26 (81.3%) publications, osteochondral defects (n=2, 6.3%), consequences of poliomyelitis (n=4, 12.5%), congenital deformities (n=4, 12.5%), hemophilia (n= 2, 6.25%), idiopathic juvenile osteoarthritis (n=1, 3.1%), rheumatoid OA (n=1, 3.1%). Despite the more than 50-year history of ADA, there is still no sufficient understanding of this methodology. The goal of future research is to understand the exact indications for ADA depending on the stage, etiology, and type of AOA. ADA is a promising effective method of treatment that allows achieving an improvement in function and a reduction in pain in the medium and long term while preserving the patient's joint.

Review
BACKGROUND
Conflict situations, armed or not, have been associated with emergence and transmission of infectious diseases. This review aims to identify the pathways through which infectious diseases emerge within conflict situations and to outline appropriate infectious disease preparedness and response strategies.
METHODS
A systematic review was performed representing published evidence from January 2000 to October 2023. Ovid Medline and Embase were utilised to obtain literature on infectious diseases in any conflict settings. The systematic review adhered to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis). No geographical restrictions were imposed.
FINDINGS
Our review identified 51 studies covering AIDS, Hepatitis B, Tuberculosis, Cholera, Coronavirus 2, Ebola, Poliomyelitis, Malaria, Leishmaniasis, Measles, Diphtheria, Dengue and Acute Bacterial Meningitis within conflict settings in Europe, Middle East, Asia, and Africa since October 2023. Key factors contributing to disease emergence and transmission in conflict situations included population displacement, destruction of vital infrastructure, reduction in functioning healthcare systems and healthcare personnel, disruption of disease control programmes (including reduced surveillance, diagnostic delays, and interrupted vaccinations), reduced access by healthcare providers to populations within areas of active conflict, increased population vulnerability due to limited access to healthcare services, and disruptions in the supply chain of safe water, food, and medication. To mitigate these infectious disease risks reported preparedness and response strategies included both disease-specific intervention strategies as well as broader concepts such as the education of conflict-affected populations through infectious disease awareness programmes, investing in and enabling health care in locations with displaced populations, intensifying immunisation campaigns, and ensuring political commitment and intersectoral collaborations between governments and international organisations.
CONCLUSION
Conflict plays a direct and indirect role in the transmission and propagation of infectious diseases. The findings from this review can assist decision-makers in the development of evidence-based preparedness and response strategies for the timely and effective containment of infectious disease outbreaks in conflict zones and amongst conflict-driven displaced populations.

Review
OBJECTIVES
To assess the accumulated knowledge of the effects of public health emergencies of international concern on disease control and local health systems, and contribute to a better understanding of their effects on health programs and systems.
METHODS
This was a systematic review of published and gray literature (in English, Portuguese, or Spanish). Electronic databases (BVS/LILACS, PubMed, and SciELO) and Google Scholar were searched. Search terms were: COVID-19 OR H1N1 OR Ebola OR Zika OR poliomyelitis AND (outbreaks OR epidemics) AND (public health systems OR public health surveillance).
RESULTS
A total of 3 508 studies were retrieved, of which 31 met the inclusion criteria. The studies addressed the effects of the emergencies on: communicable diseases notification systems; malaria, HIV/AIDS, tuberculosis, poliomyelitis, and malaria surveillance, control, and treatment; microcephaly; dengue; and vaccinations. The populations affected by the emergencies experienced reduced health services, which included fewer health visits, failures in the diagnostic chain, decrease in vaccination, and increased incidence or underreporting of notifiable diseases.
CONCLUSIONS
Socioeconomic inequity is a determinant of the effects of public health emergencies of international concern within affected populations. The diversion of resources and attention from health authorities disproportionately affects vulnerable populations and can lead, over time, to a weakening of health systems. The analysis of the effects of public health emergencies is important for the development of new protocols that can better respond to future crises.

Meta-Analysis
OBJECTIVE
To evaluate and assess the effectiveness of muscle strengthening and cardiovascular interventions in improving outcomes in poliomyelitis (polio) survivors.
DATA SOURCES
A systematic literature search was conducted in Medline, PubMed, CINAHL, PsychINFO, Web of Science, and Google Scholar for experimental and observational studies. Study selection and extraction: Screening, data-extraction, risk of bias and quality assessment were carried out independently by the authors. The quality appraisal and risk of bias were assessed using the Downs and Black Checklist. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed to increase clarity of reporting.
DATA SYNTHESIS
A total of 21 studies that met all the inclusion criteria were subjected to statistical analyses according to intervention (muscle strengthening or cardiovascular fitness). A random-effects meta-analysis showed a statistically significant effect for the exercise interventions favouring improvement in outcomes according to the International Classification of Functioning, Disability and Health (ICF).
CONCLUSION
This review provides further insight into the effects associated with muscle strengthening and cardiovascular interventions among polio survivors, and helps to further identify the current state of research in this area. Future research is needed, focusing on individualized approaches to exercise with polio survivors and specific exercise prescription recommendations, based on established frameworks, such as the ICF.

Expert Opinion on Drug Safety May 2024Vaccine-associated paralytic poliomyelitis (VAPP) is a rare adverse event of oral poliovirus vaccines (OPV), particularly affecting immunodeficient individuals.
BACKGROUND
Vaccine-associated paralytic poliomyelitis (VAPP) is a rare adverse event of oral poliovirus vaccines (OPV), particularly affecting immunodeficient individuals.
RESEARCH DESIGN AND METHODS
This study aimed to (1) Assess the association between OPV and VAPP using Vaccine Adverse Event Reporting System (VAERS) database (2) Outline patient characteristics and risk factors associated with the occurrence of VAPP in OPV recipients through a systematic review of case reports and case series. A disproportionality analysis was conducted using the data from VAERS, encompassing adverse events reported from 1990 till February 2023. Additionally, we conducted a systematic review of case reports and case series using PubMed, Scopus, and Embase databases.
RESULTS
The VAERS data revealed 130 VAPP reports among 1,739,903 OPV linked adverse events, with year 2010 reporting the strongest association. The systematic review of 37 studies highlighted VAPP occurrence within 2 months to 4 years post-vaccination, typically with acute flaccid paralysis. Immunodeficiency and perianal abscess emerged as major risk factors. Out of the 37 included studies, 27 showed consistent causal association of VAPP with OPV using WHO-AEFI causality assessment tool.
CONCLUSION
The study emphasized the seriousness of VAPP and highlights its association with OPV, identifying immunodeficiency as a prominent contributor to VAPP manifestation.

BACKGROUND
Sleep disturbances, especially sleep disordered breathing and sleep movement disorders, seem to be highly prevalent among aging polio survivors. They could contribute to late functional deterioration, fatigue, poor quality of life and negative health outcomes, thereby increasing cardiovascular risk.
OBJECTIVES
This review focused on current knowledge of the prevalence of sleep disorders in polio survivors, their features, predictive factors and management.
DATA SOURCES
Articles were searched in PubMed and the Cochrane Library up to March 2018.
STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS
Articles needed to 1) be written in English; 2) include only participants with previous poliomyelitis or post-polio syndrome diagnosis; and 3) involve any form of sleep disorders. Articles about isolated fatigue or non-specific sleep complaints as well as non-polio specific articles (neuromuscular disorders) were not included in the qualitative analysis.
RESULTS
Among 166 studies identified, 41 were included in this review. The prevalence of sleep apnea syndrome, nocturnal alveolar hypoventilation and restless legs syndrome seemed higher than in the general population (from 7.3% to 65%, 15% to 20% and 28% to 63%, respectively). This review highlights the lack of randomised studies assessing sleep disorder management in this specific population.
LIMITATIONS
Because of the small number of eligible publications, none was excluded for methodological limitations, and only a qualitative analysis was provided.
CONCLUSIONS AND IMPLICATIONS
Follow-up of polio survivors should include systematic screening for sleep disorders because they are associated with adverse consequences. Sleep disorder evaluation and management should improve the long-term survival and quality of life of polio survivors. Methodologically robust clinical trials are needed, but the decreasing prevalence and large clinical spectrum of the disease may complicate the creation of comparable groups.

: Established in 1994, Pakistan's polio program demonstrated early success. However, despite over 120 supplementary immunization activities in the last decade, polio eradication efforts in Pakistan have been unable to achieve their objective of halting polio transmission. Variable governance, and inconsistent leadership and accountability have hindered the success of the polio program and the quality of the campaigns. Insecurity and terrorism has interrupted polio activities, and community fears and misbeliefs about polio vaccinations continue to persist.: The article consists of a systematic review of the barriers and facilitators associated with the delivery of polio eradication activities in Pakistan. We also provide a comprehensive review of the policy and programmatic decisions made by the Pakistan Polio Programme since 1994. Searches were conducted on Embase and Medline databases and 25 gray literature sources.: Polio eradication efforts must be integrated with other preventive health services, particularly immunization services. Addressing the underlying causes of polio refusals including underdevelopment and social exclusion will help counteract resistance to polio vaccination. Achieving polio eradication will require building health systems that provide comprehensive community-centered care, and improving governance and systems of accountability.

Meta-Analysis
Pertussis, diphtheria, and tetanus (DTP)-containing vaccines combined with polio vaccines are recommended by the World Health Organization as part of routine immunization programs. The decline of immunity after vaccination has been considered as a possible reason for the reemergence of vaccine-preventable diseases worldwide. In this study, we evaluated the potential duration of protective immunity of pertussis, diphtheria, tetanus, and polio through a systematic review and meta-analysis. We examined data on immunological and clinical outcomes. We observed evidence of waning postvaccination immunity for pertussis and diphtheria, whereas tetanus and polio vaccines provided sustained protection. Further research on the risk factors of waning immunity after vaccination and the optimal timing of booster doses for pertussis and diphtheria is needed.

Comparative Study Meta-Analysis
BACKGROUND
The eradication of wild and vaccine-derived poliovirus requires the global withdrawal of oral poliovirus vaccines (OPVs) and replacement with inactivated poliovirus vaccines (IPVs). The first phase of this effort was the withdrawal of the serotype 2 vaccine in April 2016, with a switch from trivalent OPVs to bivalent OPVs. The aim of our study was to produce comparative estimates of humoral and intestinal mucosal immunity associated with different routine immunisation schedules.
METHODS
We did a random-effect meta-analysis with single proportions and a network meta-analysis in a Bayesian framework to synthesise direct and indirect data. We searched MEDLINE and the Cochrane Library Central Register of Controlled Trials for randomised controlled trials published from Jan 1, 1980, to Nov 1, 2018, comparing poliovirus immunisation schedules in a primary series. Only trials done outside western Europe or North America and without variation in age schedules (ie, age at administration of the vaccine) between study groups were included in the analyses, because trials in high-income settings differ in vaccine immunogenicity and schedules from other settings and to ensure consistency within the network of trials. Data were extracted directly from the published reports. We assessed seroconversion against poliovirus serotypes 1, 2, and 3, and intestinal immunity against serotype 2, measured by absence of shedding poliovirus after a challenge OPV dose.
FINDINGS
We identified 437 unique studies; of them, 17 studies with a maximum of 8279 evaluable infants were eligible for assessment of humoral immunity, and eight studies with 4254 infants were eligible for intestinal immunity. For serotype 2, there was low between-trial heterogeneity in the data (τ=0·05, 95% credible interval [CrI] 0·009-0·15) and the risk ratio (RR) of seroconversion after three doses of bivalent OPVs was 0·14 (95% CrI 0·11-0·17) compared with three doses of trivalent OPVs. The addition of one or two full doses of an IPV after a bivalent OPV schedule increased the RR to 0·85 (0·75-1·0) and 1·1 (0·98-1·4). However, the addition of an IPV to bivalent OPV schedules did not significantly increase intestinal immunity (0·33, 0·18-0·61), compared with trivalent OPVs alone. For serotypes 1 and 3, there was susbstantial inconsistency and between-trial heterogeneity between direct and indirect effects, so we only present pooled estmates on seroconversion, which were at least 80% for serotype 1 and at least 88% for serotype 3 for all vaccine schedules.
INTERPRETATION
For WHO's polio eradication programme, the addition of one IPV dose for all birth cohorts should be prioritised to protect against paralysis caused by type 2 poliovirus; however, this inclusion will not prevent transmission or circulation in areas with faecal-oral transmission.

BACKGROUND
As operative techniques and implant design have evolved over time, total hip arthroplasty (THA) is increasingly being carried out for patients with neurological impairment. This patient group places unique surgical challenges to the arthroplasty surgeon, which may include contractures, instability, and altered muscular tone. The purpose of this systematic review is to report the patient outcomes, complications, and implant survival following THA for patients with neurological conditions affecting the hip. Thus, we aim to support orthopaedic surgeon decision-making when considering and planning THA for these patients.
METHODS
A systematic review was performed as per Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using the PubMed/Medline OVID, Cochrane, and Embase databases. All studies reporting the outcomes of THA in the neurological population which met defined inclusion criteria were included.
RESULTS
From an initial screen of 1820 studies, 45 studies with a total of 36,251 THAs were included in the final selection. All 45 studies reported complication rates, with controls included in 16 for comparison. High complication rates were observed following THA in the neurologically impaired population, most notably dislocation with observed rates up to 10.6%. An improvement was noted in all 36 studies (1811 THAs) which reported upon patient-reported outcomes.
CONCLUSIONS
THA may be beneficial in the selected patients with neurological conditions, to reduce pain and improve function. There is an increased risk of complications which require careful consideration when planning the operation and open discussion with prospective patients and caregivers before proceeding with surgery.
