Review
BACKGROUND
One of the most important steps in increasing the nurses' professional competence and consequently improving the quality of nursing care is to evaluate nurses' clinical competency and then take effective actions to enhance it. This study aimed at exploring the clinical competence of Iranian nurses and factors related to it.
MATERIALS AND METHODS
In this systematic review and meta-analysis, PubMed, Scopus, Web of Science, Scientific Information Database, and Iranmedex databases and Google Scholar search engine were searched to February 14, 2020.
RESULTS
After screening, a total of 25 articles were included. In general, the level of clinical competence of Iranian nurses was at a desirable level. After meta-analysis of the mean score of nurses' clinical competence, the combined mean was 161.13 (95% confidence interval [CI]: 137.78-184.48; < 0.001; = 99.8%; P value for heterogeneity = < 0.001) by the Competency Inventory for Registered Nurses (CIRN) questionnaire. The summarized mean of clinical competency measured by the Nurse Competence Scale (NCS) questionnaire was 70.75 (95% CI: 60.80-80.70; < 0.001; = 99.9%; value for heterogeneity = < 0.001). Factors affecting nurses' clinical competence were age ≥33 years, nursing work experience ≥9 years, and a master's degree in nursing. However, the clinical competence of nurses had a significant negative relationship with job stress.
CONCLUSION
The level of clinical competence of Iranian nurses was desirable. Studies that used the CIRN, reported the highest and lowest clinical competence in clinical care and professional development dimensions, respectively. Studies that used the NCS, reported the highest and lowest clinical competence in dimensions of work role and ensuring quality, respectively.

Meta-Analysis
Digital clubbing and hypertrophic osteoarthropathy (HOA) are long-standing clinical entities, but their prevalence have not been synthesized. We aimed to estimate the prevalence of digital clubbing and HOA in people with existing medical conditions.We comprehensively searched PubMed, Embase, and Web of Science to select studies addressing HOA or digital clubbing and published through March 23, 2021. Summary estimates of the prevalence were derived through random-effects meta-analysis and narrative synthesis. The review protocol has been registered with PROSPERO, CRD42021243934.Of 3973 records, we included 142 studies. In adults, the pooled prevalence of digital clubbing was 33.4% (95% confidence interval [CI], 16.6-52.8), 31.3% (95% CI, 22.4-41.1), 27% (95% CI, 9.4-49.5), and 22.8% (95% CI, 10.8-37.6) in subjects with intestinal diseases, interstitial lung diseases, infective endocarditis, and hepatic diseases, respectively. In children and adolescents, the pooled prevalence of digital clubbing was 29.1% (95% CI, 19.4-39.9), 23% (95% CI, 9.0-41.1), 19.5% (95% CI, 4.1-42.4), and 17.1% (95% CI, 9.5-26.5) in subjects with human immunodeficiency virus infection, hemoglobinopathies, cystic fibrosis, and tuberculosis. The pooled prevalence of HOA was 10.1% (95% CI, 2.0-23.1) in adults with cancers, and 5% (95% CI, 2.5-8.2) in children and adolescents with cystic fibrosis.In conclusion, the prevalence of digital clubbing varied across disease groups in both adults and children. Full-spectrum HOA was mostly reported in adults with liver disease and cancers, and in children and adolescents with cystic fibrosis.

Review
BACKGROUND
Thalassaemia is a quantitative abnormality of haemoglobin caused by mutations in genes controlling production of alpha or beta globins. Abnormally unpaired globin chains cause membrane damage and cell death within organ systems and destruction of erythroid precursors in the bone marrow, leading to haemolytic anaemia. The life-long management of the general health effects of thalassaemia is highly challenging, and failure to deal with dental and orthodontic complications exacerbates the public health, financial and personal burden of the condition. There is a lack of evidence-based guidelines to help care seekers and providers manage such dental and orthodontic complications. This review aimed to evaluate the available evidence on methods for treating dental and orthodontic complications in people with thalassaemia to inform future recommendations. This is an update of a Cochrane Review first published in 2019.
OBJECTIVES
To assess different methods for treating dental and orthodontic complications in people with thalassaemia.
SEARCH METHODS
We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register in September 2022, and we searched nine online databases and trials registries in January 2022. We searched the reference lists of relevant articles and reviews and contacted haematologists, experts in fields of dentistry, organisations, pharmaceutical companies and researchers working in this field.
SELECTION CRITERIA
We searched for published or unpublished randomised controlled trials (RCTs) that evaluated treatment of dental and orthodontic complications in individuals diagnosed with thalassaemia, irrespective of phenotype, severity, age, sex and ethnic origin.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the 37,242 titles retrieved by the search. After deduplication, we identified two potentially relevant RCTs. On assessing their eligibility against our inclusion and exclusion criteria, we excluded one and included the other.
MAIN RESULTS
We included one parallel-design RCT conducted in Saudi Arabia and involving 29 participants (19 males, 10 females) with thalassaemia. It aimed to assess the effectiveness of photodynamic therapy as an adjuvant to conventional full-mouth ultrasonic scaling for the treatment of gingivitis. The average age of participants was around 23 years. There is very low-certainty evidence from this trial that full-mouth ultrasonic scaling plus photodynamic therapy compared to full-mouth ultrasonic scaling alone may improve gingival index score and bleeding on probing after 12 weeks in people with thalassaemia. We found no studies that assessed other interventions for the various dental or orthodontic complications of thalassaemia.
AUTHORS' CONCLUSIONS
Although the included study showed greater reduction in gingivitis in the group treated with full-mouth ultrasonic scaling plus photodynamic therapy, the evidence is of very low certainty. The study had unclear risk of bias, a short follow-up period and no data on safety or adverse effects. We cannot make definitive recommendations for clinical practice based on the limited evidence of a single trial. Future studies will very likely affect the conclusions of this review. This review highlights the need for high-quality RCTs that investigate the effectiveness of various treatment modalities for dental and orthodontic complications in people with thalassaemia. It is crucial that future trials assess adverse effects of interventions.

Review
OBJECT
Arsenic as a chemical is found in rock, soil, air and used in various industries and their products, such as colors, hairs, and fertilizers. Humans may be exposed to arsenic mainly through food and drinking water. Due to its adverse health effects, its presence in drinking water has become a public health concern.
METHODS
In this systematic review, we investigated the relationship between arsenic concentration in drinking water and the risk of kidney cancer in humans. For this reason, various electronic databases were searched from 1992 February to November 2021. In this review, three ecological studies, two case-control studies, and four cohort studies were investigated.
RESULTS
High levels of arsenic (100 μg/L) have been reported in many countries such as southwest Taiwan, Niigata, Argentine, and northern Chile. A significant relationship was observed between kidney cancer incidence and its mortality rate with high arsenic levels in drinking water.
CONCLUSIONS
Despite the limitations in some previous studies, reviewing and comparing the data of different regions indicates a scientific relationship between kidney cancer incidence and high concentrations of arsenic in drinking water.

Meta-Analysis
Advancements in orally bioavailable iron chelators and MRI methods have improved life expectancy and reproductive potential in thalassemia major (TM) and thalassemia intermedia (TI). Pregnancy is associated with adverse maternal and neonatal outcomes, frequency of which has not been well delineated. This systematic review aims to provide risk estimates of maternal and fetal outcomes in TM and TI and explore pregnancy's impact on iron homeostasis. Fifteen studies (429 participants, 684 pregnancies) were included. Meta-analysis revealed a higher thrombosis risk in TI (3.7%) compared to TM (0.92%), unchanged from prepregnancy. Heart failure risks in the earlier years appeared similar (TM 1.6% vs TI 1.1%), and maternal mortality in TM was 3.7%, but with current management, these risks are rare. Gestational diabetes and pre-eclampsia occurred in 3.9% and 11.3% of TM pregnancies, respectively. Caesarean section rates were 83.9% in TM and 67% in TI. No significant difference in stillbirth, small for gestational age neonates, or preterm birth incidence between TM and TI was observed. In TM pregnancies, red cell requirements significantly increased (from 102 to 139 ml/kg/year, P = 0.001), and 70% of TI pregnancies required blood transfusions. As expected, increased transfusion alongside chelation cessation led to a significant increase in serum ferritin during pregnancy (TM by 1005 ng/mL; TI by 332 ng/mL, P < 0.0001). Deterioration in iron status was further reflected by an increase in liver iron concentration (from 4.6 to 11.9 mg/g dry weight, P < 0.0001), and myocardial T2-star (T2∗) magnetic resonance imaging decreased (from 36.2 ± 2.5 ms to 31.1 ms) during pregnancy. These findings emphasize the elevated maternal risk of iron-related cardiomyopathy during pregnancy and labor, stressing the importance of cardiac monitoring and postpartum chelation therapy resumption.

BACKGROUND AIMS
Amidst the success of cell therapy for the treatment of onco-hematological diseases, the first recently Food and Drug Administration-approved gene therapy product for patients with transfusion-dependent β-thalassemia (TDT) indicates the feasibility of gene therapy as curative for genetic hematologic disorders. This work analyzed the current-world scenario of clinical trials involving gene therapy for β-hemoglobinopathies.
METHODS
Eighteen trials for patients with sickle cell disease (SCD) and 24 for patients with TDT were analyzed.
RESULTS
Most are phase 1 and 2 trials, funded by the industry and are currently recruiting volunteers. Treatment strategies for both diseases are fetal hemoglobin induction (52.4%); addition of wild-type or therapeutic β-globin gene (38.1%) and correction of mutations (9,5%). Gene editing (52.4%) and gene addition (40.5%) are the two most used techniques. The United States and France are the countries with the greatest number of clinical trials centers for SCD, with 83.1% and 4.2%, respectively. The United States (41.1%), China (26%) and Italy (6.8%) lead TDT trials centers.
CONCLUSIONS
Geographic trial concentration indicates the high costs of this technology, logistical issues and social challenges that need to be overcome for gene therapy to reach low- and middle-income countries where SCD and TDT are prevalent and where they most impact the patient's health.

Meta-Analysis Review
During the coronavirus-19 disease (COVID-19) pandemic, several studies were performed to determine the mortality and incidence rates of coronavirus infection among patients with hemoglobinopathies. However, there has been no systematic approach or meta-analysis to evaluate the results worldwide. This meta-analysis summarized the existing evidence of incidence and mortality rates of COVID-19 and related risk factors among patients with hemoglobinopathies with a focus on β-thalassemia (β-thal) and sickle cell disease. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Two authors independently screened the articles, extracted eligible ones, and assessed the quality of studies using the Joanna Briggs Institute (JBI) checklist. The collected data were analyzed by the Stata software. The amount of heterogeneity was demonstrated by the I test. The incidence of COVID-19 among patients with a hemoglobinopathy, β-thal and sickle cell disease was 4.44, 1.34, and 17.22 per 100,000 person-day, respectively, to June 15 2020. The mortality rate of COVID-19 in patients with hemoglobin (Hb) disorders was calculated as 1.07 per 1000 person-day in the same period. Our findings showed a higher incidence rate of COVID-19 in sickle cell disease patients compared to the general population. A slightly higher mortality rate was also observed in patients with hemoglobinopathies compared to the general population, possibly due to the associated risk factors and comorbidities in this vulnerable group, which underscore special care, timely diagnosis and management along with current immunization, were crucial in decreasing the frequency, disease severity and mortality of these patients.

Meta-Analysis Review
Numerous studies have linked coronavirus disease 2019 (COVID-19) with endothelial dysfunction and reported elevated levels of endothelial biomarkers in this disease. We conducted a systematic review and meta-analysis of the published evidence in this respect. A systematic literature search of PubMed and Scopus databases was performed to find studies investigating biomarkers of endothelial dysfunction in COVID-19 patients. Pooled standardized mean differences and their 95% confidence intervals were calculated for each biomarker using random effect model. 74 studies with 7668 patients were included. In comparison to patients with good outcome, those with poor outcome had higher levels of von Willebrand factor (vWF) (SMD: 0.83, 95% CI: 0.59-1.07, p < 0.00001), vWF:ADAMTS13 (1.23, (0.77-1.7), p < 0.00001), angiopoietin-2 (Ang-2) (1.06 (0.6-1.51), p < 0.0001), E-selectin (1.09 (0.55-1.63), p < 0.0001), P-selectin (0.59 (0.24-0.94), p = 0.001), syndecan-1 (0.99 (0.6-1.37), p < 0.00001), mid-regional pro-adrenomedullin (MR-proADM) (1.52 (1.35-1.68), p < 0.00001), vascular endothelial growth factor (0.27 (0.02-0.53), p = 0.03), soluble fms-like tyrosine kinase-1 (sFLT-1) (1.93 (0.65-3.21), p = 0.03) and lower levels of ADAMTS13 antigen (-0.69 (-0.9 to -0.47) p < 0.00001) and activity (-0.84 (-1.06 to -0.61) p < 0.0000). Plasminogen activator inhibitor-1 and tissue plasminogen activator levels were not different between the two groups (p < 0.05). There were elevated levels of endothelial dysfunction biomarkers in COVID-19 patients with poor outcome, indicating their possible role in disease severity and prognosis. In particular, MR-proADM, vWF, syndecan-1 and sFLT-1 showed a significant association with poor outcome in these patients.

Meta-Analysis Review
OBJECTIVE
The aim of this study was to identify the prevalence of orofacial alterations in sickle-cell disease (SCD) and to compare it with the general population.
STUDY DESIGN
This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The search was conducted on PubMed, Embase, Scientific Electronic Library Online, Web of Science, Cochrane Library, gray literature, and references of the included articles.
RESULTS
A total of 770 records were found, and 28 studies were selected. In SCD, the prevalence of decreased bone density was 57% (95% CI: 35%-80%), with Q: P < .01 and I = 95%; for stepladder pattern was 30% (IC: 13%-47%), Q: P < .01 and I²: 93%; for delayed eruption was 20% (95% CI: 6%-34%), with Q: P < .01 and I = 86, Q: P < .01 and I = 99%; and for malocclusion, 66% (95% CI: 39%-92%), Q: P < .01 and I = 98%. A high risk of bias was observed in relation to the sample size of the studies. A limited number of articles compared the prevalence of orofacial alterations in patients with SCD and healthy individuals.
CONCLUSIONS
Decreased bone density, malocclusion, orofacial pain, tooth necrosis, eruption delay, periodontal disease, and neuropathies may be present in patients with SCD with variable prevalence.

Review
BACKGROUND
Sickle cell disease (SCD), one of the commonest severe monogenic disorders, is caused by the inheritance of two abnormal haemoglobin (beta-globin) genes. SCD can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Kidney disease is a frequent and potentially severe complication in people with SCD. Chronic kidney disease (CKD) is defined as abnormalities of kidney structure or function present for more than three months. Sickle cell nephropathy refers to the spectrum of kidney complications in SCD. Glomerular damage is a cause of microalbuminuria and can develop at an early age in children with SCD, with increased prevalence in adulthood. In people with sickle cell nephropathy, outcomes are poor as a result of the progression to proteinuria and chronic kidney insufficiency. Up to 12% of people who develop sickle cell nephropathy will develop end-stage renal disease. This is an update of a review first published in 2017.
OBJECTIVES
To assess the effectiveness of any intervention for preventing or reducing kidney complications or chronic kidney disease in people with sickle cell disease. Possible interventions include red blood cell transfusions, hydroxyurea, and angiotensin-converting enzyme inhibitors (ACEIs), either alone or in combination.
SEARCH METHODS
We searched for relevant trials in the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, CENTRAL, MEDLINE, Embase, seven other databases, and two other trials registers.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing interventions to prevent or reduce kidney complications or CKD in people with SCD. We applied no restrictions related to outcomes examined, language, or publication status.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial eligibility, extracted data, assessed the risk of bias, and assessed the certainty of the evidence (GRADE).
MAIN RESULTS
We included three RCTs with 385 participants. We rated the certainty of the evidence as low to very low across different outcomes according to GRADE methodology, downgrading for risk of bias concerns, indirectness, and imprecision. Hydroxyurea versus placebo One RCT published in 2011 compared hydroxyurea to placebo in 193 children aged nine to 18 months. We are unsure if hydroxyurea compared to placebo reduces or prevents progression of kidney disease assessed by change in glomerular filtration rate (mean difference (MD) 0.58 mL/min /1.73 m, 95% confidence interval (CI) -14.60 to 15.76; 142 participants; very low certainty). Hydroxyurea compared to placebo may improve the ability to concentrate urine (MD 42.23 mOsm/kg, 95% CI 12.14 to 72.32; 178 participants; low certainty), and may make little or no difference to SCD-related serious adverse events, including acute chest syndrome (risk ratio (RR) 0.39, 99% CI 0.13 to 1.16; 193 participants; low certainty), painful crisis (RR 0.68, 99% CI 0.45 to 1.02; 193 participants; low certainty); and hospitalisations (RR 0.83, 99% CI 0.68 to 1.01; 193 participants; low certainty). No deaths occurred in either trial arm and the RCT did not report quality of life. Angiotensin-converting enzyme inhibitors versus placebo One RCT published in 1998 compared an ACEI (captopril) to placebo in 22 adults with normal blood pressure and microalbuminuria. We are unsure if captopril compared to placebo reduces proteinuria (MD -49.00 mg/day, 95% CI -124.10 to 26.10; 22 participants; very low certainty). We are unsure if captopril reduces or prevents kidney disease as measured by creatinine clearance; the trial authors stated that creatinine clearance remained constant over six months in both groups, but provided no comparative data (very low certainty). The RCT did not report serious adverse events, all-cause mortality, or quality of life. Angiotensin-converting enzyme inhibitors versus vitamin C One RCT published in 2020 compared an ACEI (lisinopril) with vitamin C in 170 children aged one to 18 years with normal blood pressure and microalbuminuria. It reported no data we could analyse. We are unsure if lisinopril compared to vitamin C reduces proteinuria in this population: the large drop in microalbuminuria in both arms of the trial after only one month on treatment may have been due to an overestimation of microalbuminuria at baseline rather than a true effect. The RCT did not report serious adverse events, all-cause mortality, or quality of life.
AUTHORS' CONCLUSIONS
We are unsure if hydroxyurea improves glomerular filtration rate or reduces hyperfiltration in children aged nine to 18 months, but it may improve their ability to concentrate urine and may make little or no difference to the incidence of acute chest syndrome, painful crises, and hospitalisations. We are unsure if ACEI compared to placebo has any effect on preventing or reducing kidney complications in adults with normal blood pressure and microalbuminuria. We are unsure if ACEI compared to vitamin C has any effect on preventing or reducing kidney complications in children with normal blood pressure and microalbuminuria. No RCTs assessed red blood cell transfusions or any combined interventions to prevent or reduce kidney complications. Due to lack of evidence, we cannot comment on the management of children aged over 18 months or adults with any known genotype of SCD. We have identified a lack of adequately designed and powered studies, although we found four ongoing trials since the last version of this review. Only one ongoing trial addresses renal function as a primary outcome in the short term, but such interventions have long-term effects. Trials of hydroxyurea, ACEIs or red blood cell transfusion in older children and adults are urgently needed to determine any effect on prevention or reduction of kidney complications in people with SCD.
