RESUMEN
AIM: To conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the effectiveness of real-time continuous glucose monitoring (rtCGM) versus intermittently scanned continuous glucose monitoring (isCGM) on key glycaemic metrics (co-primary outcomes HbA1c and time-in-range [TIR] 70-180 mg/dL, 3.9-10.0 mmol/L) among people with type 1 diabetes (T1D). METHODS: Medline, PubMed, Scopus, Web of Science and Cochrane Central Register of clinical trials were searched. Inclusion criteria were RCTs; T1D populations of any age and insulin regimen; comparing any type of rtCGM with isCGM (only the first generation had been compared to date); and reporting the glycaemic outcomes. Glycaemic outcomes were extracted post-intervention and expressed as mean differences and 95% CIs between the two comparators. Results were pooled using a random-effect meta-analysis. The risk of bias was assessed using the Cochrane RoB2 tool. The quality of evidence was assessed by the GRADE approach. RESULTS: Five RCTs met the inclusion criteria (4 parallel and 1 crossover design; 4 with CGM use <8 weeks), involving 446 participants (354 adults; 92 children and adolescents). Overall, meta-analysis showed rtCGM compared to isCGM improved absolute TIR by +7.0% (95% CI: 5.8%-8.3%, I2 = 0%, p < 0.01) accompanied by a favorable effect on time-below-range <70 mg/dL (3.9 mmol/L) - 1.7% (95%CI: -3.0% to -0.4%; p = 0.03). No differences were seen regarding HbA1c. CONCLUSIONS: This meta-analysis highlights that for people with T1D, rtCGM confers benefits over isCGM primarily related to increased TIR, with improvements in hypo- and hyperglycaemia.

BACKGROUND: Syphilis, a disease once in decline, has made a resurgence worldwide. New Zealand has had increasing syphilis rates since enhanced syphilis surveillance was initiated in 2013. This study reports epidemiologic, descriptive and treatment data on management of infants prenatally exposed or vertically infected with syphilis across New Zealand as reported by pediatricians. METHODS: Over a 26-month period from April 2018 to May 2020 (inclusive), pediatricians throughout New Zealand notified potential, probable and confirmed cases of congenital syphilis to the New Zealand Pediatric Surveillance Unit. National reporting numbers were concurrently ascertained to demonstrate reporting accuracy. RESULTS: Thirty-two cases were notified, comprised of 25 infants born to women with positive antenatal syphilis serology (5 whom developed congenital syphilis), and 7 infants diagnosed with congenital syphilis after birth where syphilis was not diagnosed in pregnancy. There were 12 cases of congenital syphilis; an incidence rate of 9.4 cases per 100,000 live births. Nine of the 12 infants had clinical features of congenital syphilis. One-third of maternal infections were early syphilis, and the women who gave birth to infected infants were less likely to have received antenatal care, adequate treatment and follow-up monitoring of treatment for syphilis during pregnancy. CONCLUSIONS: This study quantifies an important burden of disease from congenital syphilis in our population. Case finding and treatment of syphilis in pregnancy are critical to prevent this. Our findings support the urgent need for measures such as repeat maternal syphilis screening in early third trimester; whether by affected region or instituted for all, in the context of rising cases.
