Exploring the Impact of Iron Deficiency Anaemia on Glycated Haemoglobin A1c Levels in Pregnant and Non-Pregnant Women: A Systematic Review.

Haemoglobin A1C (HbA1c) is fundamental in monitoring glycaemic control during pregnancy. However, several conditions could affect this test's accuracy, including iron deficiency anaemia (IDA). Hence, this systematic review delves into the underexplored connection between IDA, iron replacement therapy (IRT), and haemoglobin A1C (HbA1c) during pregnancy. An electronic search of the Cochrane, MEDLINE, and Embase databases was conducted by six authors. From a comprehensive search strategy, 968 records were obtained. After applying the inclusion and exclusion criteria, seven studies were included, comprising 365 women selected for analysis. Six studies indicated a positive correlation between IDA and HbA1c levels, while one found no correlation. The average HbA1c level of the included studies in pregnant women was 5.64%. In comparison, it was found that non-pregnant women had lower HbA1c levels. Among the included studies, the mean HbA1c levels decreased from 5.1% to 4.89% after treating pregnant women with IRT. The review emphasises the complexity of interpreting HbA1c levels in pregnant women with IDA, highlighting the influence of pregnancy-induced physiological changes. In addition, this suggests that HbA1c should not be the sole criterion for diabetes management in pregnant women with IDA. Future research should focus on alternative glycaemic monitoring methods unaffected by IDA.

Diagnostic accuracy of intrathecal fluorescein versus other radiological modalities in evaluating non-congenital skull base defects: a systematic review and meta-analysis.

PURPOSE: The intraoperative detection of cerebrospinal fluid (CSF) leaks during endoscopic skull base surgery is critical to ensure watertight sealed defects. Intrathecal fluorescein (ITF) is a valuable adjunct to intraoperative investigation. Hence, our aim is to summarize the evidence of the efficacy of ITF as an accurate diagnostic modality and reconstruction guide for non-congenital skull base defects. METHODS: Using the Cochrane Central, MEDLINE, and Embase databases, we identified studies involving the use of ITF in non-congenital CSF leaks which were published until November 2023. The STATA 18 software was used for meta-analysis. RESULTS: Fourteen studies met the inclusion criteria, in which seven studies were included in the meta-analysis. ITF was used in 1898 (90.3%) of patients, with a detection rate of 88.1%. The overall detection rate of non-congenital CSF leaks among ITF concentrations of 5% and 10% had a statistically significant pooled effect size of 2.6 (95% CI = 2.25, 2.95), while when comparing the ITF to other alternative radiological tests, it was not statistically significant with a mean difference of 0.88 (95% CI = - 0.4, 2.16). Moreover, the pooled prevalence was statistically significant in regards of the complications associated with ITF with an effect size of 0.6 (95% CI = 0.39, 0.82), indicating that 60% of patients who underwent ITF would experience at least one of the measured complications. CONCLUSION: ITF is considered as an efficient tool in localizing skull base defects. However, there was no significant results when comparing the ITF to other alternative radiological tests. Accordingly, if the ITF intervention is indicated, patients should be carefully selected based on their clinical need.

The Effect of Iron Replacement Therapy on HbA1c Levels in Diabetic and Nondiabetic Patients: A Systematic Review and Meta-Analysis.

BACKGROUND: Several studies have reported that iron-deficiency anemia (IDA) and its treatment might lead to a distorted reading of glycated hemoglobin (HbA1c) value. Hence, this review aims to systematically investigate the effect of iron replacement therapy (IRT) on HbA1c levels, as the literature is deficient in assessing this clinical phenomenon. METHODS: An electronic search of the Cochrane, MEDLINE, and Embase databases was conducted by four independent authors. RESULTS: Among the 8332 articles identified using the search strategy, 10 records (with a total of 2113 participants) met the inclusion criteria and were analyzed. In nine of the studies, IRT was found to decrease HbA1c levels; in the remaining study, IRT was found to increase HbA1c levels. The effect size of the pooled standardized mean difference in HbA1c levels between the treatment and control groups with IDA was 1.8 (95% CI = -0.5, 2.31). Heterogeneity was assessed using the I2 and χ2 tests, and the resultant values were 98.46% and p = 0.09, respectively. Additionally, the mean difference between the HbA1c levels (pre-IRT and post-IRT) showed a drop in the HbA1c levels which ranged from 1.20 to 0.43 mg/dL. CONCLUSIONS: The results suggest that IRT decreases HbA1c levels, and it is helpful in treating IDA patients with poor glycemic control. Accordingly, the results provide an added perspective on antidiabetic medication dosing and physicians' interpretation of initially elevated HbA1c values.

Non-obstetric Acute Abdomen in Pregnancy: a Review of Literature.

Background: Acute abdomen in pregnancy (AAP) is defined as intensive abdominal pain lasting less than 24 hours that may require urgent surgery. It is a challenging situation to diagnose and manage, as it is associated with pain due to the normal anatomical and physiological changes that occur during pregnancy. Objective: Therefore, understanding these changes and their effect on almost every system, will help us appreciate the upcoming causes of AAP, mainly the non-obstetric surgical emergencies (e.g., appendicitis, cholecystitis). Methods: This article highlights the importance of the well-rounded care that should be offered to every pregnant patient presenting to any center with a Non-obstetric Acute Abdomen. The causes are discussed separately (for surgical pearls), laparoscopic approach and radiologic modality decision-making in pregnancy, which is an academic and a practice-based helpful summary. Results and Discussion: This article highlights the importance of the well-rounded care that should be offered to every pregnant patient presenting to any center with a Non-obstetric Acute Abdomen. The causes are discussed separately (for surgical pearls), laparoscopic approach and radiologic modality decision-making in pregnancy, which is an academic and a practice-based helpful summary. Results and Discussion: In addition, the sequence of ideas and language used in the article was based to help the reader understand the topic, rather than inform them about it. In addition, the utility of laparoscopy in pregnancy remains a concern due to the possible risk of injury to the fetus and fetal acidosis. Although, trials showed that laparoscopy was associated with less blood loss and a shorter hospital stay. Moreover, in some cases radiographic imaging is necessary, posing a diagnostic dilemma. Conclusion: AAP is a major concern that requires early interventions to pinpoint the cause and manage the patient, properly.
