PURPOSE OF REVIEW
Tracheostomized patients are medically complex and vulnerable. International attention is now focused on improving the safety and quality of their care. This review summarizes recent evidence in hot-topic areas pertinent to speech and language therapy (SLT) intervention for dysphagia management in tracheostomized patients.
RECENT FINDINGS
The management of tracheostomized patients requires a truly multidisciplinary team (MDT) approach. Without this, patients remain tracheostomized and hospitalized for longer and have slower access to MDT members. Patterns of SLT intervention are variable across the United Kingdom, and further work to achieve consensus on best practice is required. Instrumental evaluation of swallowing provides vital information and can facilitate well tolerated oral feeding even prior to cuff deflation. A systematic review suggests that sensitivity of blue-dye testing is poor, but studies are methodologically flawed. The need for tracheostomy-specific quality of life measures is being addressed by the development of a questionnaire.
SUMMARY
In this review, the main research themes relevant to speech and language therapists (SLTs) working with tracheostomized patients are discussed. This patient group poses significant challenges to robust study design. However, recent advances in uniting MDT members globally to improve standards of care are encouraging.

Meta-Analysis Review
PURPOSE
Endoscopic biopsy is recommended for diagnosis of nasopharyngeal carcinoma (NPC). A proportion of lesions are hidden from endoscopic view but detected with magnetic resonance imaging (MRI). This systematic review and meta-analysis investigated the diagnostic performance of MRI for detection of NPC.
METHODS
An electronic search of twelve databases and registries was performed. Studies were included if they compared the diagnostic accuracy of MRI to a reference standard (histopathology) in patients suspected of having NPC. The primary outcome was accuracy for detection of NPC. Random-effects models were used to pool outcomes for sensitivity, specificity, and positive and negative likelihood ratio (LR). Bias and applicability were assessed using the modified QUADAS-2 tool.
RESULTS
Nine studies were included involving 1736 patients of whom 337 were diagnosed with NPC. MRI demonstrated a pooled sensitivity of 98.1% (95% CI 95.2-99.3%), specificity of 91.7% (95% CI 88.3-94.2%), negative LR of 0.02 (95% CI 0.01-0.05), and positive LR of 11.9 (95% CI 8.35-16.81) for detection of NPC. Most studies were performed in regions where NPC is endemic, and there was a risk of selection bias due to inclusion of retrospective studies and one case-control study. There was limited reporting of study randomization strategy.
CONCLUSION
This study demonstrates that MRI has a high pooled sensitivity, specificity, and negative predictive value for detection of NPC. MRI may be useful for lesion detection prior to endoscopic biopsy and aid the decision to avoid biopsy in patients with a low post-test probability of disease.

Meta-Analysis Review
Several studies have reported the value of neutrophil-to-lymphocyte ratio (NLR) for the prognosis of hypopharyngeal cancer. However, contradictory findings have also been published. We aimed to clarify the effect of NLR on the prognosis of hypopharyngeal cancer through meta-analysis. Systematic search of PubMed and other database with study selection and data extraction. The combined hazard ratio (HR) and 95% confidence intervals (CI) were calculated using STATA, applying either a fixed-effects or random-effects model. Meta-regression, subgroup analysis, and sensitivity analysis were used to analyze sources of heterogeneity. Publication bias were also assessed. This meta-analysis included 2232 patients with hypopharyngeal cancer from seven studies. The combined HR (OS, HR = 1.80, 95CI%, 1.14-2.82; PFS, HR = 1.88, 95CI%, 1.26-2.79) suggested that high NLR was associated with poor overall survival (OS) and progression-free survival (PFS). Pretreatment NLR can be used as an effective serological indicator to assess the prognosis of patients with hypopharyngeal cancer.

Review
Infection with HPV virus and exposure to extrinsic carcinogens are the main causative factors for oropharyngeal squamous cell carcinoma (OPSCC). While HPV-related OPSCC typically shows a better prognosis and may be a candidate for de-intensification therapy, there is a subset of HPV-related cancers that show aggressive phenotype with frequent metastatic spread. The identification and refinement of molecular markers can better serve for prediction of prognosis and thus improve treatment decisions and outcome. We conducted a systematic review according to the PRISMA guidelines of all relevant studies addressing novel biomarkers in publications prior to July 2021. We identified studies that evaluated the association between molecular markers and prognosis in HPV-positive OPSCC. Full-text publications were entirely reviewed, classified, and selected if a clear predictive/prognostic value was seen in patients with HPV-positive OPSCC. Furthermore, a functional analysis of the target genes was conducted to understand biological processes and molecular pathways impacting on HPV-positive OPSCC outcomes. The systematic review yielded a total of 14 studies that matched the inclusion and exclusion criteria. Differential expression was identified for 31 different biomarkers. The first common pattern identified was the association of HPV-related circulating antibodies to activated immune function. Second, gene-gene interaction analysis further identified interacting gene networks tightly implicated in hypoxia tumor metabolism including the Warburg effect. Survival in HPV-positive OPSCC can be predicted by distinct selective biomarkers mainly indicative of immune host response and oxidative metabolism. Among these markers, some were identified to be unsuitable for HPV-positive de-escalation trials aimed at improving patients' quality of life.

Review
BACKGROUND
Gastrostomy has been established as the standard procedure for administering long-term enteral nutrition in individuals with swallowing disturbances. Percutaneous gastrostomy is a less-invasive approach than open surgical gastrostomy, and can be accomplished via endoscopy (percutaneous endoscopic gastrostomy or PEG) or sonographic or fluoroscopic guidance (percutaneous radiological gastrostomy or PRG). Both techniques have different limitations, advantages, and contraindications. In order to determine the optimal technique for long-term nutritional supplementation many studies have been conducted to compare the outcomes of these two techniques; however, it remains unclear as to which method is superior to the other with respect to both efficacy and safety.
OBJECTIVES
To compare the safety and efficacy of PEG and PRG in the treatment of individuals with swallowing disturbances.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, January 2016); MEDLINE (1946 to 22 January 2016); EMBASE (1980 to 22 January 2016); the reference lists of identified articles; databases of ongoing trials, including the Chinese Cochrane Centre Controlled Trials Register; and PubMed. We applied no language restrictions.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing PEG with PRG in individuals with swallowing disturbances, regardless of the underlying disease.
DATA COLLECTION AND ANALYSIS
Two authors independently evaluated the search results and assessed the quality of the studies. Data analyses could not be performed as no RCTs were identified for inclusion in this review.
MAIN RESULTS
We identified no RCTs comparing PEG and PRG for percutaneous gastrostomy in individuals with swallowing disturbances. The large body of evidence in this field comes from retrospective and non-randomised controlled studies and case series. Based on this evidence, both PEG and PRG can be safely performed in selected individuals, although both are associated with major and minor complications. A definitive RCT has yet to be conducted to identify the preferred percutaneous gastrostomy technique.
AUTHORS' CONCLUSIONS
Both PEG and PRG are effective for long-term enteral nutritional support in selected individuals, though current evidence is insufficient to recommend one technique over the other. Choice of technique should be based on indications and contraindications, operator experience and the facilities available. Large-scale RCTs are required to compare the two techniques and to determine the optimal approach for percutaneous gastrostomy.

Meta-Analysis Review
OBJECTIVE
To evaluate outcomes of injection laryngoplasty (IL) and endoscopic surgical repair for the treatment of type 1 laryngeal clefts (LC1) and to determine the most common presentations of LC1.
METHODS
Primary studies were searched for in PubMed, Scopus, OVID, and Cochrane Library using search terms laryngeal cleft and laryngotracheoesophageal cleft for articles published from database inception through August 2019. The search identified all articles pertaining to the symptomatology and management of LC1. Meta-analysis was performed on presenting symptoms and improvement of clinical symptoms and swallow function.
RESULTS
Twenty-four studies, comprising 713 patients with a mean age of 33.7 months (range 0-168 months), were included. The most common presenting symptoms were aspiration (80%, CI [55%-96%]), dysphagia (61%, CI [47%-74%]), and choking (57%, CI [37%-76%]). Gastroesophageal reflux disease (GERD) was the most common comorbidity (68%, CI [51%-83%]) and premature birth comprised 27% [21%-32%] of the patients. Overall, 38% of patients received IL as a primary therapy. Prior to injection, 91% [87%-94%] of patients aspirated on swallow evaluations, and 62% [55%-68%] aspirated post-injection. At an average follow-up time of 6.8 months, 90% [70%-100%] of parents reported symptom improvement. An additional 54% of patients underwent endoscopic surgical repair as primary treatment. The rate of aspiration decreased from 73% [43%-94%] to 28% [13%-46%] after repair. At a mean follow-up of 14.2 months, 80% [67%-91%] reported symptom improvement.
CONCLUSION
A high level of clinical suspicion is necessary to detect LC1 since its most common presenting symptoms overlap with other diseases commonly found in this patient population. Both IL and formal surgical repair were effective in managing LC1.

Review
INTRODUCTION
Arcanobacterium haemolyticum causes pharyngotonsillitis in children and young adults. It is rarely isolated in pharyngeal swabs as testing for it is not routine. Data on complications, management, and antibiotic susceptibility testing is limited. We sought to review the available literature on the presentation and management of A. haemolyticum pharyngotonsillitis in this age group.
METHODS
A systematic review of eligible studies reporting pharyngotonsillitis and related complications in children and young adults caused by A. haemolyticum was conducted. Literature from case reports, case series, and available cohorts was compiled. Data were analyzed using descriptive statistics.
RESULTS
The initial database search yielded 63 articles, after applying exclusion criteria 17 studies were included. 191 patients were identified with a median age of 16.5 years. The most common presentation was throat pain reported in 93.7% of patients. Tonsillar exudates, fever at presentation and rash were present in more than half of the reviewed cases. The diagnosis was established by a positive culture on a pharyngeal swab in 98.8% of swabs collected. Complications described included peritonsillar abscesses, Lemierre's syndrome, pneumonia, and sepsis. Penicillin was the first line antibiotic in 81% of patients followed by macrolides in 19 patients (18%).
CONCLUSIONS
A. haemolyticum occurs in children and young adults and may result in complications. Our review supports its susceptibility to penicillin. We suggest a diagnostic and management algorithm to guide clinicians in targeted testing and aid with decision making regarding timely and appropriate antibiotic therapy, in an effort to reduce the burden of its complications.

Meta-Analysis
Time to negative throat culture following initiation of antibiotics for pharyngeal group A : a systematic review and meta-analysis up to October 2021 to inform public health control measures.
BackgroundPublic health guidance recommending isolation of individuals with group A streptococcal (GAS) infection or carriage for 12-24 h from antibiotic initiation to prevent onward transmission requires a strong evidence base.AimTo estimate the pooled proportion of individuals who remain GAS culture-positive at set intervals after initiation of antibiotics through a systematic literature review (PROSPERO CRD42021290364) and meta-analysis.MethodsWe searched Ovid MEDLINE (1946-), EMBASE (1974-) and Cochrane library. We included interventional or observational studies with ≥ 10 participants reporting rates of GAS throat culture positivity during antibiotic treatment for culture-confirmed GAS pharyngitis, scarlet fever and asymptomatic pharyngeal GAS carriage. We did not apply age, language or geographical restrictions.ResultsOf 5,058 unique records, 43 were included (37 randomised controlled studies, three non-randomised controlled trials and three before-and-after studies). The proportion of individuals remaining culture-positive on day 1, day 2 and days 3-9 were 6.9% (95% CI: 2.7-16.8%), 5.4% (95% CI: 2.1-13.3%) and 2.6% (95% CI: 1.6-4.2%). For penicillins and cephalosporins, day 1 positivity was 6.5% (95% CI: 2.5-16.1%) and 1.6% (95% CI: 0.04-42.9%), respectively. Overall, for 9.1% (95% CI: 7.3-11.3), throat swabs collected after completion of therapy were GAS culture-positive. Only six studies had low risk of bias.ConclusionsOur review provides evidence that antibiotics for pharyngeal GAS achieve a high rate of culture conversion within 24 h but highlights the need for further research given methodological limitations of published studies and imprecision of pooled estimates. Further evidence is needed for non-beta-lactam antibiotics and asymptomatic individuals.

Review
Dysphagia is associated with aspiration, pneumonia, and malnutrition, but remains challenging to identify at the bedside. A variety of exam protocols and maneuvers are commonly used, but the efficacy of these maneuvers is highly variable. We conducted a comprehensive search of 7 databases, including MEDLINE, Embase, and Scopus, from each database's earliest inception through June 9, 2014. Studies reporting diagnostic performance of a bedside examination maneuver compared to a reference gold standard (videofluoroscopic swallow study or flexible endoscopic evaluation of swallowing with sensory testing) were included for analysis. From each study, data were abstracted based on the type of diagnostic method and reference standard study population and inclusion/exclusion characteristics, design, and prediction of aspiration. The search strategy identified 38 articles meeting inclusion criteria. Overall, most bedside examinations lacked sufficient sensitivity to be used for screening purposes across all patient populations examined. Individual studies found dysphonia assessments, abnormal pharyngeal sensation assessments, dual axis accelerometry, and 1 description of water swallow testing to be sensitive tools, but none were reported as consistently sensitive. A preponderance of identified studies was in poststroke adults, limiting the generalizability of results. No bedside screening protocol has been shown to provide adequate predictive value for presence of aspiration. Several individual exam maneuvers demonstrated reasonable sensitivity, but reproducibility and consistency of these protocols was not established. More research is needed to design an optimal protocol for dysphagia detection.

INTRODUCTION
allergy may be an important risk factor for adenotonsillar disease in children, although conflicting results have been reported in the literature. In previous articles, authors often failed in distinguishing between adeno-tonsillar hypertrophy and recurrent tonsillitis and in not discriminating between isolated or combined adenoid and tonsillar hypertrophy.
AIM
to evaluate clinical evidence and biomarkers linking allergy to different phenotypes of adeno-tonsillar disease. Furthermore, we questioned whether anti-allergy treatment might prevent occurrence of adeno-tonsillar disease or improve its specific management.
METHODS
our systematic review, in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process, yielded 1010 articles finally screened. This resulted in 21 full texts that were included in a qualitative analysis.
RESULTS
literature data support the association between allergy and combined adeno-tonsillar hypertrophy and isolated adenoid hypertrophy, whereas describe a mainly negative correlation between allergy and isolated tonsillar hypertrophy. The results of this review suggest that local allergic inflammation may play a role in adeno-tonsillar hypertrophy. Data correlating bacterial recurrent tonsillitis and allergy are few, although evidence from the lab revealed that allergy might suppress innate immunity in tonsillar tissue by reducing levels of anti-microbial proteins.
CONCLUSION
basing on our qualitative analyses allergy should not be misdiagnosed in children with combined adenotonsillar hypertrophy or isolated adenoid hypertrophy, whereas evidence do not support a link between allergy and isolated tonsil hypertrophy. Finally, some data support a link between allergy and recurrent adeno-tonsillar infection although future studies are required to confirm this data. We summarized our conclusions in a practical algorithm.
