Meta-Analysis Review
BACKGROUND
Osteoarthritis (OA) affecting the first metatarsophalangeal joint (hallux rigidus) is common and painful. Several non-surgical treatments have been proposed; however, few have been adequately evaluated. Since the original 2010 review, several studies have been published necessitating this update.
OBJECTIVES
To determine the benefits and harms of non-surgical treatments for big toe OA.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search was February 2023.
SELECTION CRITERIA
We included randomised trials that compared any type of non-surgical treatment versus placebo (or sham), no treatment (such as wait-and-see) or other treatment.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. The major outcomes were pain, function, quality of life, radiographic joint structure, adverse events and withdrawals due to adverse events. The primary time point was 12 weeks. We used GRADE to assess the certainty of evidence.
MAIN RESULTS
This update includes six trials (547 participants). The mean age of participants ranged from 32 to 62 years. Trial durations ranged from 4 to 52 weeks. Treatments were compared in single trials as follows: arch-contouring foot orthoses versus sham inserts; shoe-stiffening inserts versus sham inserts; intra-articular injection of hyaluronic acid versus saline (placebo) injection; arch-contouring foot orthoses versus rocker-sole footwear; peloid therapy versus paraffin therapy; and sesamoid mobilisation, flexor hallucis longus strengthening and gait training plus physical therapy versus physical therapy alone. Certainty of the evidence was limited by the risk of bias and imprecision. Meta-analysis was not performed due to the heterogeneity of interventions. We reported numerical data for the 12-week time point for the three trials that used a placebo/sham control group. Arch-contouring foot orthoses versus sham inserts One trial (88 participants) showed that arch-contouring foot orthoses probably lead to little or no difference in pain, function, or quality of life compared to sham inserts (moderate certainty). Mean pain (0-10 scale, 0 no pain) with sham inserts was 3.9 points compared to 3.5 points with arch-contouring foot orthoses; a difference of 0.4 points better (95% (CI) 0.5 worse to 1.3 better). Mean function (0-100 scale, 100 best function) with sham inserts was 73.3 points compared to 65.5 points with arch-contouring foot orthoses; a difference of 7.8 points worse (95% CI 17.8 worse to 2.2 better). Mean quality of life (-0.04-100 scale, 100 best score) with sham inserts was 0.8 points compared to 0.8 points with arch-contouring foot orthoses group (95% CI 0.1 worse to 0.1 better). Arch-contouring foot orthoses may show little or no difference in adverse events and withdrawal due to adverse events compared to sham inserts (low certainty). Adverse events (mostly foot pain) were reported in 6 out of 41 people with sham inserts and 4 out of 47 people with arch-contouring foot orthoses (RR 0.58, 95% CI 0.18 to 1.92). Withdrawals due to adverse events were reported in 0 out of 41 people with sham inserts and 1 out of 47 people with arch-contouring foot orthoses (Peto OR 6.58, 95% CI 0.13 to 331). Shoe-stiffening inserts versus sham inserts One trial (100 participants) showed that shoe-stiffening inserts probably lead to little or no difference in pain, function, or quality of life when compared to sham inserts (moderate certainty). Mean pain (0-100 scale, 0 no pain) with sham inserts was 63.8 points compared to 70.1 points with shoe-stiffening inserts; a difference of 6.3 points better (95% CI 0.5 worse to 13.1 better). Mean function (0-100 scale, 100 best function) with sham inserts was 81.0 points compared to 84.9 points with shoe-stiffening inserts; a difference of 3.9 points better (95% CI 3.3 worse to 11.1 better). Mean quality of life (0-100 scale, 100 best score) with sham inserts was 53.2 points compared to 53.3 points with shoe-stiffening inserts; a difference of 0.1 points better (95% CI 3.7 worse to 3.9 better). Shoe-stiffening inserts may show little or no difference in adverse events and withdrawal due to adverse events, compared to sham inserts (low certainty). Adverse events (mostly foot pain, blisters, and spine/hip pain) were reported in 31 out of 51 people with sham inserts and 29 out of 49 people with shoe-stiffening inserts (RR 0.94, 95% CI 0.42 to 2.08). Withdrawals due to adverse events were reported in 1 out of 51 people with sham inserts and 2 out of 49 people with shoe-stiffening inserts (Peto OR 2.08, 95% CI 0.19 to 22.23). Hyaluronic acid versus placebo One trial (151 participants) showed that a single intra-articular injection of hyaluronic acid probably leads to little or no difference in pain or function compared to placebo (moderate certainty). Mean pain (0-100 scale, 0 no pain) with placebo was 72.5 points compared to 68.2 points with hyaluronic acid; a difference of 4.3 points better (95% CI 2.1 worse to 10.7 better). Mean function (0-100 scale, 100 best function) was 83.4 points with placebo compared to 85.0 points with hyaluronic acid; a difference of 1.6 points better (95% CI 4.6 worse to 7.8 better). Hyaluronic acid may provide little or no difference in quality of life (0-100 scale, 100 best score) which was 79.9 points with placebo compared to 82.9 points with hyaluronic acid; a difference of 3.0 better (95% CI 1.4 worse to 7.4 better; low certainty). There may be fewer adverse events with hyaluronic acid compared to placebo. Adverse events (mostly pain at the injection site) were reported in 43 out of 76 people with placebo compared with 27 out of 75 people with hyaluronic acid (RR 0.64, 95% CI 0.44 to 0.91; low certainty). No participants withdrew from either group due to adverse events. The effects on radiographic joint structure were not reported in any study.
AUTHORS' CONCLUSIONS
The existing evidence regarding the benefits and harms of non-surgical treatments for big toe OA is limited. There is moderate-certainty evidence, based upon three single placebo/sham-controlled trials, that there are no clinically important benefits of arch-contouring foot orthoses, shoe-stiffening inserts, or a single intra-articular injection of hyaluronic acid. Further placebo-controlled trials are needed to evaluate the effectiveness of non-surgical treatments for big toe OA.

Review
BACKGROUND
This review aims to determine the potential role of Merkel Cell Polyomavirus (MCPyV) in the pathogenesis of cervical squamous cell carcinomas and adenocarcinomas.
METHODS
A PRISMA systematic search appraisal was conducted. The Scopus, Web of Science, PubMed, EMBASE, Google Scholar, and MEDLINE databases for publications in English were searched up to September 2022 for all relevant articles. All articles that have outlined the contributions of the MCPyV to cervical squamous cell carcinomas and adenocarcinomas were included.
RESULTS
The six databases produced 6806 articles. Only six articles met the inclusion criteria and were included. The protocol of this review was submitted and registered with the PROSPERO (Code no. CRD42022369197). The total sample size across the articles was 1135; the age of the participants ranged between 18 and 75 years. In addition, the included articles were conducted between 2012 to 2016. All included articles have a cross-sectional design.Furthermore, different kinds of samples were collected in the reviewed articles, namely cervical tissue biopsies, cervical smears, formalin-fixed paraffin-embedded resection specimens, and cervical adenocarcinomas. Moreover, five articles showed no statistically significant association between the MCPyV and cervical squamous cell carcinomas and adenocarcinomas. In contrast, one article revealed a positive association between MCPyV and cervical squamous cell carcinomas and adenocarcinomas.
CONCLUSIONS
MCPyV could not be associated with the pathogenesis of cervical squamous cell carcinomas and adenocarcinomas. Further attention should be given to examining this association, and further studies with a large sample size are recommended to confirm these findings.

Meta-Analysis Review
Some studies suggested that gastrointestinal (GIT) decontamination with oil may improve the prognosis of patients who ingested aluminum phosphide (AlP). The aim of this study is to compare the efficacy and safety of gastric lavage with oil-based solutions to any method of gastric decontamination not using oils in patients presenting with acute AlP poisoning. The literature was searched for English-published randomized controlled trials (RCTs) from inception to 16 September 2023. The searched electronic databases included MEDLINE/PubMed, Cochrane Library, Web of Science, Egyptian Knowledge Bank, Scopus, and Google Scholar. Data were extracted and pooled by calculating the risk ratio (RR) for categorical outcomes and standardized mean difference (SMD) for numerical outcomes, with 95% confidence intervals (CI). Seven RCTs were included. Paraffin oil was significantly associated with a lower risk of mortality (RR = 0.59 [95% CI: 0.45, 0.76], < .001), intubation (RR = 0.59 [95% CI: 0.46, 0.76], < .001) and vasopressor need (RR = 0.71 [95% CI: 0.56, 0.91], = .006). Survival time was significantly prolonged with paraffin oil (SMD = 0.72 [95% CI: 0.32, 1.13], < .001). Coconut oil was significantly associated with prolonged survival time (SMD = 0.83 [95% CI: 0.06, 1.59], = .03) as well as decreased risk of requiring intubation (RR = 0.78 [95% CI: 0.62, 0.99], = .04). Oil-based GIT decontamination using paraffin oil showed benefits over conventional lavage regarding the incidence of in-hospital mortality and endotracheal intubation, and survival time. Coconut oil showed some benefits in terms of the intubation incidence and survival time. Decontamination using paraffin oil is recommended. Future clinical trials are warranted with larger sample sizes and focusing on cost-benefit and safety.

Review
INTRODUCTION
Aluminum Phosphide (AlP) poisoning constituted the most common cause of poisoning death in some low- and middle-income countries (LMICs). This study aimed to evaluate the safety and efficacy of oil-based gastric lavage (GL) compared with standard therapy for the treatment of AlP poisoning. Materials and methods. This systematic review complied with "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) Protocols. A comprehensive search was carried out, identifying randomized controlled trials (RCTs), including anyone presenting within 6 h of exposure to AlP, and the administration of GL with oils, including liquid paraffin or coconut oil.
RESULTS
We identified 7 RCTs. The evidence from 4 RCTs indicates that GL with paraffin oil is an effective treatment for acute AlP poisoning, decreasing the mortality rate (RR = 0.62; 95% CI = 0.48 to 0.81; participants = 226; I = 10%; ). We estimate the Number Needed to Treat of 4. Likewise, this intervention reduces the need for intubation and mechanical ventilation (RR = 0.62; 95% CI = 0.40 to 0.79; I = 0%; ). Regarding GL with coconut oil, the evidence from 4 RCTs, indicates a slight reduction in mortality (RR = 0.82; 95% CI = 0.69 to 0.98; participants = 112; I = 0%; ).
CONCLUSIONS
Limited evidence suggests that GL with paraffin oil is effective in reducing the mortality rate. Likewise, limited evidence showed in favor of paraffin oil concerning the need for intubation and mechanical ventilation. Very limited evidence suggests that GL with coconut oil could reduce mortality. Both interventions would have a benign safety profile.

The infiltration of substances into the buttocks for esthetic purposes can cause local or systemic damage. These infiltrated substances, known as adjuvants, foreign substances, and polymers, often lack sufficient and frequently controversial evidence. To identify the systemic complications associated with substances locally infiltrated in the buttocks for treatment, we conducted a systematic review following the PRISMA criteria. Of 275 publications, 29 met the eligibility criteria: 3 systematic reviews, 6 case series, and 20 case reports. The study comprises 463 cases, mainly women (87%), with an average age of 39.94 years. The average time between infiltrations was 7.65 years. Infiltrated substances included silicone, oils, methyl methacrylate, guaiacol, sodium gadolinium, collagen, paraffin, and other unknown substances. The complications fell into three categories: local, systemic with inflammatory-immune response, and renal damage due to hypercalcemia induced by the granulomatosis caused by the substance. Treatment lacked uniformity, mainly focusing on the main effect. Surgical resection of affected tissue resulted in local and systemic improvement (renal, hypercalcemia, or inflammatory-immune) for most patients. Patients who received comprehensive treatment based on inflammatory-immune control, control of renal involvement, and resection of the tissue area that contained large amounts of the infiltrated substance had a better prognosis than those with diffuse infiltration and delayed treatment.

Review
The purpose of this systematic review is to summarize all existing evidence, regarding the immunohistochemical expression of REV-7 in different human cancer pathology specimens. Moreover, the association of REV-7 expression with disease severity (clinical course), patients' survival, prognosis, and response to various treatments, such as chemotherapy and irradiation, was investigated. Three databases (PubMed, Scopus, and Cochrane) were systematically screened, from inception to September 2, 2023, as suggested by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Only studies using immunohistochemical staining for REV-7 in paraffin-embedded cancer tissues were included. Nine studies met the inclusion criteria and were included in the final qualitative synthesis. All nine studies were retrospective and non-comparative ones. Selected studies reported immunohistochemical expression of REV-7 in different types of cancer, including testicular cancer, ovarian cancer, esophagus squamous cell carcinoma, prostate cancer, colorectal cancer, diffuse large B-cell lymphoma, breast cancer, lung cancer, and skin cancer. High REV-7 expression was associated with faster disease progression, resistance to available treatment options, and worse prognosis in the majority of included studies. These results indicate that immunohistochemical staining of REV-7 protein could potentially be used as a predictive tissue marker in certain cases. Promising results, arising from REV-7 inactivation experiments, render REV-7 targeting a potential therapeutic strategy for future cancer management, especially in the cases of chemoresistant or radioresistant disease.

Review
PURPOSE
Human papilloma virus (HPV)-positive head and neck squamous cell carcinoma (HNSCC) displays distinct epidemiological, clinical, and molecular characteristics compared to the negative counterpart. Alterations in autophagy play an important role in cancer, and emerging evidence indicates an interplay of autophagy in HNSCC carcinogenesis and tumor promotion. However, the influence of HPV infection on autophagy in HNSCC has received less attention and has not been previously reviewed. Therefore, we here aimed to systematically review the role of autophagy explicitly in HPV HNSCC.
METHODS
Studies accessible in PubMed, Embase, Scopus, and Web of Science investigating HNSCC, highlighting the molecular biological differences between HPV and HPV HNSCC and its influences on autophagy in HNSCC were analyzed according to the PRISMA statement. A total of 10 articles were identified, included, and summarized.
RESULTS
The HPV16 E7 oncoprotein was reported to be involved in the degradation of AMBRA1 and STING, and to enhance chemotherapy-induced cell death via lethal mitophagy in HNSCC cells. Autophagy-associated gene signatures correlated with HPV-subtype and overall survival. Additionally, immunohistochemical (IHC) analyses indicate that high LC3B expression correlates with poor overall survival in oropharyngeal HNSCC patients.
CONCLUSION
HPV may dampen general bulk autophagic flux via degradation of AMBRA1 but may promote selective autophagic degradation of STING and mitochondria. Interpretations of correlations between autophagy-associated gene expressions or IHC analyses of autophagy-related (ATG) proteins in paraffin embedded tissue with clinicopathological features without biological validation need to be taken with caution.

Management of Uremic Xerosis and Chronic Kidney Disease (CKD)-Associated Pruritus (CKD-ap) With Topical Preparations: A Systematic Review and Implications in the Indian Context.
Uremic xerosis and chronic kidney disease (CKD)-associated pruritus (CKD-ap) are the most commonly occurring dermatological problems faced by most of the CKD patients on hemodialysis which are not only annoying and draining to the patients but also have an intense effect on patients' quality of life. The PubMed, Scopus, Google Scholar, and Web of Science databases were searched for the literature with the following search terms: uremic xerosis OR CKD-ap OR uremic pruritus AND topical therapy OR topical ointment OR natural oil from the year 2002 -2022, and finally, 22 articles were chosen to write this review. Out of 22 studies, six used pharmacological preparations and remaining 16 studies used natural oils and components. All the articles were experimental studies (Pre/Quazi/RCT/True experimental) focusing on managing itch and xerosis associated with CKD and hemodialysis by topical application. The topical agents tried in various research studies are effective in managing itch and xerosis associated with CKD. They are safe, easy to use, and without allergic reactions. Natural oils like almond, chia seed, clove, glycerin, paraffin, and virgin coconut oil are readily available in home-care settings and can be used as a nurse-led intervention. Topical preparations for uremic xerosis and pruritus are effective, safe, and easy to apply on large body surface areas without systematic side effects. Natural oil-based topical preparations are cost-effective, safe, and easy to use.

Review
Salivary myeloperoxidase (MPO) is a key mediator of the oral immune system, acting as an enzyme that utilises HO to generate molecules with high bactericidal activity. While MPO determination in plasma is quite common, the use of saliva is still rare. Our systematic review was designed to answer the question "Are salivary levels of myeloperoxidase altered in patients with systemic diseases?". Following the inclusion and exclusion criteria, we included twenty-six studies. Altered MPO levels in saliva were most commonly found in patients with cardiovascular and gastrointestinal diseases. Most studies concerned unstimulated whole saliva, and only a few of them stimulated, mainly by chewing paraffin. Enzyme-linked immunosorbent assay (ELISA) was the most common method for determination of MPO concentrations in saliva. Increased salivary MPO levels were more often observed for inflammatory diseases, except patients with inflammatory bowel diseases who were eligible for biologic therapy. In conclusion, MPO could be altered in the saliva of patients with systematic diseases, especially cardiovascular or gastrointestinal diseases. However, further investigations are recommended to validate these outcomes.

Meta-Analysis
To review the available studies on the frequency of detection of the bovine leukemia virus in human samples, a systematic review with meta-analysis of the scientific literature was carried out, including papers published in English, Spanish, and Portuguese in 5 multidisciplinary databases. We collected information from different populations following a detailed and reproducible search protocol in which two researchers verified the inclusion and exclusion criteria. We identified 759 articles, of which only 33 met the inclusion criteria. Analyzed studies reported that the presence of the virus was measured in human samples, such as paraffin-embedded breast tissue and peripheral blood from 10,398 individuals, through serological and molecular techniques. An overall virus frequency of 27% (Ranging between 17 and 37%) was observed, with a high-frequency data heterogeneity between studies. The presence of this virus in different human biological samples suggests the need to investigate further its transmission route to humans and its potential role in developing and progressing diseases.
