Review
Poly-L-lactic acid (PLLA) implants have been used for bone fixation for decades. However, upon insertion, they can cause a foreign body reaction (FBR) that may lead to complications. On 15 December 2023, a systematic review was conducted to search for articles on the PubMed, MeSH term, and Scopus databases using the keywords 'PLLA' and 'foreign body reaction'. The articles were reviewed not only for the question of FBR, its severity, and the manifestation of symptoms but also for the type of implant and its location in the body, the species, and the number of individuals included. A total of 71 original articles were identified. Of these, two-thirds reported on in vivo trials, and one-third reported on clinical applications. The overall majority of the reactions were mild in more than half of the investigations. Symptoms of extreme and extensive FBR mainly include osteolysis, ganglion cysts, and swelling. The localization of PLLA implants in bone can often result in osteolysis due to local acidosis. This issue can be mitigated by adding hydroxyapatite. There should be no strong FBR when PLLA is fragmented to 0.5-4 µm by extracorporeal shock wave.

INTRODUCTION
Uterine contractions during labour constrict maternal blood flow and oxygen delivery to the developing baby, causing transient hypoxia. While most babies are physiologically adapted to withstand such intrapartum hypoxia, those exposed to severe hypoxia or with poor physiological reserves may experience neurological injury or death during labour. Cardiotocography (CTG) monitoring was developed to identify babies at risk of hypoxia by detecting changes in fetal heart rate (FHR) patterns. CTG monitoring is in widespread use in intrapartum care for the detection of fetal hypoxia, but the clinical utility is limited by a relatively poor positive predictive value (PPV) of an abnormal CTG and significant inter and intra observer variability in CTG interpretation. Clinical risk and human factors may impact the quality of CTG interpretation. Misclassification of CTG traces may lead to both under-treatment (with the risk of fetal injury or death) or over-treatment (which may include unnecessary operative interventions that put both mother and baby at risk of complications). Machine learning (ML) has been applied to this problem since early 2000 and has shown potential to predict fetal hypoxia more accurately than visual interpretation of CTG alone. To consider how these tools might be translated for clinical practice, we conducted a review of ML techniques already applied to CTG classification and identified research gaps requiring investigation in order to progress towards clinical implementation.
MATERIALS AND METHOD
We used identified keywords to search databases for relevant publications on PubMed, EMBASE and IEEE Xplore. We used Preferred Reporting Items for Systematic Review and Meta-Analysis for Scoping Reviews (PRISMA-ScR). Title, abstract and full text were screened according to the inclusion criteria.
RESULTS
We included 36 studies that used signal processing and ML techniques to classify CTG. Most studies used an open-access CTG database and predominantly used fetal metabolic acidosis as the benchmark for hypoxia with varying pH levels. Various methods were used to process and extract CTG signals and several ML algorithms were used to classify CTG. We identified significant concerns over the practicality of using varying pH levels as the CTG classification benchmark. Furthermore, studies needed to be more generalised as most used the same database with a low number of subjects for an ML study.
CONCLUSION
ML studies demonstrate potential in predicting fetal hypoxia from CTG. However, more diverse datasets, standardisation of hypoxia benchmarks and enhancement of algorithms and features are needed for future clinical implementation.

Review
Why do patients with urinary diversions have an increased risk of bone fracture? A systematic review on risk factors for osteoporosis and bone mineral density loss in this group of patients.
INTRODUCTION
Patients undergoing radical cystectomy with urinary diversions (UD) are at increased risk of bone fractures compared to the general population. Although a loss of bone mineral density (BMD) has been described in patients with UD, we still do not know with certainty why these patients follow this tendency.
OBJECTIVE
We performed a systematic review of the available literature to analyze the prevalence of osteoporosis and bone alterations in patients with ileal UD and the possible associated risk factors.
EVIDENCE ACQUISITION
We systematically searched PubMed® and Cochrane Library for original articles published before December 2022 according to PRISMA guidelines.
EVIDENCE SYNTHESIS
A total of 394 publications were identified. We selected 12 studies that met the inclusion criteria with 496 patients included. Six of the twelve studies showed decreased BMD values. Prevalence of osteoporosis was specified in three articles, with values ranging from 0% to 36%. Risk factors such as age, sex, body mass index, metabolic acidosis and renal function appear to have an impact on bone tissue reduction, while type of UD, follow-up, 25-hydroxyvitamin D and parathormone had less evidence or contradictory data. The heterogeneity of the studies analyzed could led to interpretation bias.
CONCLUSIONS
UD are associated with multiple risk factors for osteoporosis and bone fractures. Identifying patients at highest risk and establishing diagnostic protocols in routine clinical practice are essential to reduce the risk of fractures and the resulting complications.

Meta-Analysis Review
AIMS
Studies suggested a higher prevalence of Attention-deficit/hyperactivity disorder (ADHD) in individuals with Type 1 Diabetes Mellitus (T1D). However, it is unclear how ADHD impacts glycemia and diabetes-related complications. This systematic review and meta-analysis aimed to investigate the effect of ADHD and ADHD medications on HbA1c and acute complications in T1D.
METHODS
A literature search was conducted in PubMed, EMBASE, CINAHL, Scopus, PsycINFO, CENTRAL, and Web of Science collections up to November 22, 2023. Seventeen studies were selected for the systematic review by independent reviewers, with twelve included in the meta-analysis.
RESULTS
Mean HbA1c levels were significantly higher in T1D individuals with ADHD compared to those without ADHD (MD = 0.60; 95 % CI: 0.41, 0.79; I = 90.1 %; p-value < 0.001). The rates of suboptimal HbA1c levels, hospitalization, diabetic ketoacidosis, and hypoglycemia were all substantially higher in T1D individuals with ADHD than those without ADHD. No difference was found in mean HbA1c between those who received ADHD treatment and those who did not (mean difference = -0.52; 95 % confidence interval: -1.16, 0.13; I = 78.6 %; p-value = 0.12).
CONCLUSIONS
ADHD is associated with higher HbA1c and increased acute diabetes-related complications. More research is needed to assess the effects of ADHD treatments on T1D management.

ST waveform analysis (STAN) was introduced to improve the interpretation of cardiotocography (CTG) resulting in reduction of unnecessary interventions and metabolic acidosis. A systematic review was conducted with the aim to evaluate the effect of STAN method compared with isolated CTG on perinatal and neonatal outcomes. A search of electronic databases (PubMed, Cochrane, Scopus) was conducted to identify randomized controlled trials (RCTs) in English language. Outcomes considered operative deliveries, fetal blood sampling (FBS), metabolic acidosis, perinatal and neonatal death, neonatal seizures, neonatal encephalopathy, transfer to the neonatal intensive care unit (NICU) and Apgar score. Seven RCTs were included in the present review. The first two RCTs showed that the combination of STAN and CTG was a better option than using CTG alone, because there was a documented reduction in the rate of operative deliveries due to fetal distress and metabolic acidosis. The following studies showed no statistically significant changes with the combination of methods, except from a reduction in FBS. The findings from the RCTs were inconclusive. Most studies did not demonstrate a superiority of the combination regarding operative deliveries and neonatal outcomes but there were many methodological differences between the trials.

Meta-Analysis
OBJECTIVES
This systematic review and meta-analysis aimed to assess the magnitude and determinants of diabetic ketoacidosis (DKA) among patients with diabetes mellitus (DM) in Ethiopia.
DESIGN
Systematic review and meta-analysis.
PARTICIPANTS
Age 15 and above all patients with diabetes with the diagnosis of DKA in Ethiopia DATA SOURCE: PubMed/MEDLINE, Cochrane Library, Science Direct, HINARI, Google Scholar and grey literatures were accessed to find relevant articles. Studies that have been conducted and reported in English language, articles with an available full-text, and observational studies were included. The task of searching sources was carried out from all stated electronic databases performed during 15 April-29 April 2023.
PRIMARY AND SECONDARY OUTCOME MEASURES
Eligible studies were critically appraised by three independent reviewers for methodological quality in the review using standardised critical appraisal instruments from Joanna Briggs Institute (JBI) for observational studies. After the finally extracted studies were exported, systematic review and meta-analysis were conducted using Unified Management, Assessment and Review of Information (JBI SUMARI) (JBI, Adelaide, Australia) and STATA V.17 software. Sensitivity tests were done, and funnel plot inspections with Egger's test were used to check for publication bias.
RESULT
From a total of 19 studies with 6498 study participants, the pooled prevalence of DKA among patients with DM in Ethiopia was 30.92% (95% CI 29.96 to 31.89) with a significant statistical heterogeneity (I=99.2, p=<0.001). Sensitivity analysis suggested that three studies showed deviations from the estimated pooled prevalence. A funnel plot inspection and Egger's test indicated the absence of a publication bias.
CONCLUSION
This systematic review and meta-analysis revealed that the prevalence of DKA among patients with DM in Ethiopia was 30.92%. Besides, different behavioural and clinical determinants of DKA among patients with DM were identified. However, further studies should be conducted, particularly on the possible determinants of DKA, and different stakeholders should be engaged to minimise its burden.

Meta-Analysis
AIMS
Chronic metabolic acidosis has been shown to be associated with cardiometabolic risk factors. The aim of the currently updated meta-analysis was to explore the association between Potential Renal Acid Load (PRAL) and Net Endogenous Acid Production (NEAP) with these risk factors.
DATA SYNTHESIS
Databases were searched up to May 2023. The mean of waist circumference (WC), body mass index (BMI), high- and low-density lipoprotein-cholesterol (HDL-C and LDL-C), triglyceride (TG), total cholesterol (TC), fasting blood sugar (FBS), and systolic- and diastolic blood pressure (SBP and DBP) in highest category vs lowest categories of NEAP and PRAL were recorded. Effect sizes were generated as weighted mean difference (WMD). Results showed that SBP, DBP, and WC had a significant difference in the upper and lower categories of PRAL (WMD: 1.466 mmHg; 95% CI: 2.121, -0.811; P<0.001, WMD: 0.710 mmHg; 95 % CI: 1.170, -0.249; P=0.003, and WMD: 0.819 cm; 95% CI: 1.446, -0.192; P=0.010) or NEAP (WMD: 1.690 mmHg; 95% CI: 2.789, -0.591; P=0.003, WMD: 1.076 mmHg, and WMD: 1.325 cm; 95% CI: 1.901, -0.749; P<0.001; 95% CI: 1.938, -0.214; P =0.014). The lowest versus highest categories of dietary PRAL were associated with lower BMI (WMD: 0.297 kg/m2; 95 % CI: 0.440, -0.154; P<0.001) and TG (WMD: 2.280 mg/dl; 95%CI: 3.828, -0.732; P=0.004; I=99.4 %; P<0.001).
CONCLUSIONS
High DAL can be considered as an independent risk factor for increasing anthropometric indices, blood pressure, and TG. This study registered in the PROSPERO database (Registration No. CRD42023402985).

Meta-Analysis
OBJECTIVE
Sodium-glucose cotransporter-2 inhibitors (SGLT2Is) reduce cardio-metabolic and renal outcomes in patients with type 2 diabetes (T2D) but their efficacy and safety in older or frail individuals remains unclear.
METHODS
We searched PubMed, Scopus, Web of Science, Cochrane CENTRA and Google Scholar and selected randomised controlled trials and observational studies comparing SGLT2Is versus placebo/other glucose-lowering agent for people with frailty or older individuals (>65 years) with T2D and heart failure (HF). Extracted data on the change in HbA1c % and safety outcomes were pooled in a random-effects meta-analysis model.
RESULTS
We included data from 20 studies (22 reports; N = 77,083 patients). SGLT2Is did not significantly reduce HbA1c level (mean difference -0.13, 95%CI: -0.41 to 0.14). SGLT2Is were associated with a significant reduction in the risk of all-cause mortality (risk ratio (RR) 0.81, 95%CI: -0.69 to 0.95), cardiac death (RR 0.80, 95%CI: -0.94 to 0.69) and hospitalisation for heart failure (HHF) (RR 0.69, 95%CI: 0.59-0.81). However, SGLT2Is did not demonstrate significant effect in reducing in the risk of macrovascular events (acute coronary syndrome or cerebral vascular occlusion), renal progression/composite renal endpoint, acute kidney injury, worsening HF, atrial fibrillation or diabetic ketoacidosis.
CONCLUSIONS
In older or frail patients with T2D and HF, SGLT2Is are consistently linked with a decrease in total mortality and the overall burden of cardiovascular (CV) events, including HHF events and cardiac death, but not protective for macrovascular death or renal events. Adverse events were more difficult to quantify but the risk of diabetic ketoacidosis or acute kidney injury was not significantly increase.

Review
The occurrence of mucormycosis has been observed in individuals with COVID-19. However, there is limited information on the epidemiological factors, presentation, diagnostic certainty, and outcome of this infection in children. PubMed, MEDLINE, Scopus, Embase, Web of Science, LitCovid, and back-references of the identified manuscripts were systematically searched from December 2019 to March 2023. We have identified 14 cases of pediatric mucormycosis in patients with COVID-19. The median age of patients was 10.7 years. Among these cases, 10 were associated with active COVID-19. In 7 cases, the patients had pre-existing diabetes mellitus and concomitant diabetic ketoacidosis. Corticosteroids were administered to treat COVID-19 in 7 of the patients. The most common clinical presentation of the disease was rhino-orbital cerebral mucormycosis. Seven patients died (50%). Given the high mortality rate, clinicians should maintain a high level of clinical suspicion of mucormycosis in pediatric patients with COVID-19.

BACKGROUND
Type B lactic acidosis and hypoglycemia can occur in various pediatric conditions. In young children with a history of fasting preceding these metabolic derangements, inborn errors of metabolism should be primarily considered. However, the Warburg effect, a rare metabolic complication, can also manifest in children with hematologic malignancies. Only a few reports of this condition in children have been published in the literature.
AIM
To identify the clinical course, treatment strategies, and outcomes of childhood hematologic malignancies with type B lactic acidosis.
METHODS
We performed a comprehensive search of the PubMed, Scopus, and Cochrane databases without any time restriction but limited to English language articles. The databases were last accessed on July 1, 2023.
RESULTS
A total of 20 publications were included in the analysis, all of which were case reports or case series. No higher quality evidence was available. Among children with hematologic malignancies and Warburg effect, there were 14 cases of acute lymphoblastic leukemia and 6 cases of non-Hodgkin's lymphoma including our illustrative case. Lactic acidosis occurred in 55% of newly diagnosed cases and 45% of relapsed cases. The mean age was 10.3 ± 4.5 years, and 80% of cases were male. The mean serum lactate was 16.9 ± 12.6 mmol/L, and 43.8% of the cases had concomitant hypoglycemia. Lactic acidosis initially subsided in 80% of patients receiving chemotherapy compared to 60% in the contrast group. The mortality rate of newly diagnosed cases was 45.5%, while the relapsed cases represented a 100% mortality rate. All 8 patients reported before 2001 died from disease-related complications. However, patients described in reports published between 2003 and 2023 had a 54.5% rate of complete remission.
CONCLUSION
This complication has historically led to fatal outcome; however, patients who received chemotherapy showed a more favorable response. Therefore, it is crucial to promptly initiate specific treatment in this context.
