RESUMO

Introduction Pressure ulcers, also known as bedsores, are a significant concern for bedridden individuals, presenting both physical and socioeconomic challenges. Factors such as prolonged immobility, chronic medical conditions, and poor nutrition contribute to their development. Despite extensive research in some regions, studies comparing diabetic and non-diabetic populations remain limited, particularly in low-income settings. This study aimed to investigate the risk factors and frequency of pressure ulcers among bedridden patients, addressing this gap in understanding and guiding targeted interventions. Materials and methods A cross-sectional study was conducted across four government hospitals in Peshawar, Pakistan. A total of 388 bedridden patients with pressure ulcers were included, and data were collected through a questionnaire. The questionnaire covered demographics, comorbidities, duration of bedbound status, BMI, and caregivers' awareness of pressure ulcer care. Data analysis was performed using SPSS version 22.0 (Armonk, NY: IBM Corp.), with qualitative data presented as frequencies and percentages and quantitative data as mean and standard deviation. Chi-square tests were utilized for significance, with p<0.05 considered significant. Results Of the 388 patients analyzed, 230 (59.3%) were diabetic, highlighting the prevalence of diabetes among pressure ulcer cases. The majority of diabetic patients with ulcers were over 41 years old, and 293 (75.5%) had comorbidities. Surgical intervention was the primary cause of ulcers in 213 (54.8%) cases, followed by stroke in 77 (19.8%) cases. Notably, 252 (65%) of caregivers exhibited inadequate knowledge regarding ulcer care. Stage II ulcers were prevalent in both diabetic and non-diabetic cohorts. Conclusions Pressure ulcers are poorly controlled complications observed in bedridden individuals, highlighting a critical need for comprehensive preventive measures and caregiver education to alleviate the burden of pressure ulcers, especially in diabetic patients. Factors such as prolonged immobility, surgical interventions, and insufficient caregiver knowledge contribute to the development of pressure ulcers. Understanding these complexities is essential for implementing effective care approaches and mitigating the impact of pressure ulcers.

RESUMO

The increasing prevalence of diabetes mellitus (DM) leads to the differentiation of the registration of diabetics in individual specialties. Objective of this paper was the evaluation of changes in the representation of expertise providing care for patients with DM (pDM) in the Czech Republic, based on data analysis from the National Register of Paid Health Services (NRHZS) 2010-2021. In the entire pDM group, the number of patients treated by a diabetologist (DIA) increased from 491,490 (57.0 %) to 537,430 (50.4 %), with a general practitioner (GP) from 27,719 (3.2 %) to 181,330 (17.0 %) and by internist (INT) from 172,918 (20.0 %) to 161,291 (15.1 %). In 2021, 57.9 % DIA, 17 % GP, 12.2 % INT were treated from the group treated with antidiabetics (813,873). In 2021, 84,345 were treated with insulin alone (87.2 % DIA), 129,127 were treated with a combination of insulin and non-insulin antidiabetics; 115,604 (91.6 %) in DIA, 322 (0.3 %) in GP and 7,983 (6.3 %) in INT. 603,331 treated only with non-insulin antidiabetic drugs, of which 281,929 (46.7 %) DIA, 137,744 (22.8 %) GP and 85,273 (14.1 %) INT. For other specialties, 98,385 (16.3 %) persons. 185,838 patients without reported DIA/GP/INT control, of which 80,144 without therapy. The increasing prevalence of DM and changes in reimbursement conditions are reflected in the dynamic development of the distribution of diabetes care by individual specialties.

RESUMO

The incidence of cataracts is significantly higher in diabetic individuals, particularly in younger age groups, with rates quadrupled in those under 65 and doubled in those over 65 compared to non-diabetics. Cataract surgery in diabetic patients poses many challenges: Poor epithelial healing, decreased corneal sensitivity, increased central corneal thickness, decreased endothelial cell count, variable topography, poor pupillary dilatation, anterior capsular phimosis, posterior capsular opacification (PCO), chances of progression of diabetic retinopathy (DR), zonular weakness, and vitreous prolapse and diabetic macular edema. Selection of an appropriate intraocular lens (IOL) is crucial for visual rehabilitation and monitoring DR. The choice of IOL in diabetic cataract patients is a challenging scenario. Square-edge IOLs are favored for their capacity to mitigate PCO, whereas hydrophilic counterparts may incur calcification in the setting of proliferative DR. The advisability of premium IOLs for achieving spectacle independence warrants judicious evaluation, particularly in the presence of advanced retinopathy. Optimal IOL placement within the capsular bag is advocated to minimize postoperative complications. Rigorous preoperative assessment and informed patient counseling regarding IOL options are indispensable for optimizing surgical outcomes. This review article covers various aspects regarding the choice of IOLs in different case scenarios and complications in the diabetic population.

RESUMO

Objective: To find the correlation of serum uric acid with microalbuminuria in Type-2 diabetic patients with normal creatinine. Methods: This cross-sectional study was conducted in the Department of Diabetes, Endocrinology and Metabolic diseases, Hayatabad Medical Complex, Peshawar, Pakistan from 1st April, 2022 to 30th September, 2022. Total 160 diabetic patients between the age of 30 and 65 years were enrolled in the study. Type-2 diabetic patients with microalbuminuria between 2.5 and 30 mg/mmol were included. The demographic details of patients were recorded in the questionnaire after taking consent. Fasting Uric acid, lipid profile and glucose along with creatinine and HbA1C were estimated from patient's venous blood samples. Ratio of albumin to creatinine (ACR) in the random spot urine sample was used to detect microalbuminuria. Results: Out of 160 participants enrolled in the study there were 86 (54%) males and 74 (46%) females with the mean age of 50.15 ± 11.1 years and BMI of 20.93 kg/m2. Ninety six (60%) of the patients had Type-2 DM for less than five years, while remaining 64 (40%) were more than five years diabetic. Mean serum uric acid calculated was 6.85±2.06(mg/dl), while microalbuminuria was calculated as 8.02±0.78 (mg/mmol). The Pearson correlation of serum uric acid and microalbuminuria based on sex and age was statistically significant(p<0.05). Conclusion: We found that uric acid level was significantly associated with microalbuminuria in people with Type-2 diabetes with normal serum creatinine. Uric acid level can be a potential screening tool for early detection of DKD.

RESUMO

Collagen, a naturally occurring fibrous protein, is a potential resource of biological materials for tissue engineering and regenerative medicine because it is structurally biocompatible, has low immunogenicity, is biodegradable, and is biomimetic. Numerous studies have documented in the literature how Collagen nanofibers exhibit limited cell adhesion, poor viscosity, and no interior fibril structure. The biomedical industry is using Poly Glycerol Sebacate prepolymer(PGSp), a biodegradable and biocompatible polyester with high adhesion and very viscous appearance, more often. Here, unique electrospun Collagen/PGSp/ZnO/NPs blend nanofibers for skin tissue application were developed and described with varied PGSp percent. Additionally, when ternary blends of Collagen, PGSp, and Zink Oxide Nanoparticles (ZnO NPs) are used, the antibacterial properties of the scaffolds are improved. The bead-free electrospun nanofibers were produced by raising the PGSp concentration to 30%w/w. SEM, EDS, tensile, MTT, FTIR, SDS-page, swelling test, contact-angle, antimicrobial, biodegradation, XRD, and cell attachment procedures were used to characterize the crosslinked nanofibers. The ternary blend nanofibers with a weight ratio of Collagen/PGSp 30%/ZnONPs 1% had higher stress/strain strength (0.25 mm/mm), porosity (563), cell survival, and degradation time. Moreover, after applying for wound healing in diabetic rats, Collagen/PGSp 30%/could be show improving wound healing significantly compared to other groups.

RESUMO

Diabetic ureteral injury (DUI) is a condition characterized by damage to the ureter, causing functional and morphological changes in the urinary system, which have a significant impact on a quality of life and requires appropriate medical treatment. The present study describes to novel design of luteolin (LT), a type of natural flavonoid, encapsulated selenium nanoparticles (Se NPs) to attain therapeutic potential for DUI. The physico-chemical characterizations of prepared Se NPs have benefitted zeta potential (-18 mV) and particle size (10-50 nm). In vitro assays were demonstrated the potential of LT-SeNPs by HEK 293 cells stimulated by STZ for DUI. Cytotoxicity assays on HEK 293 and NIH-3T3 showed >90% cell viability, which demonstrates the suitability of the nanoformulation for DUI treatment. The LT-SeNPs significantly inhibits the NLRP3 inflammasome through Nrf2/ARE pathway, which benefits for DUI treatment. The developed LT-SeNPs could be an effective formulation for the DUI therapy.

RESUMO

Background: Hemoglobin A1c (HbA1c) serves as a pivotal marker for long-term glycemic control. The Diabetes Control and Complications Trial (DCCT) established its relevance, yet gaps exist in understanding potential seasonal variations in HbA1c levels among diabetic patients. The study highlights the need to explore potential seasonal variations in HbA1c levels and their impact on diabetic patients. Materials and methods: This is an observational study conducted in a tertiary care hospital from January to December 2019, the study analyzed HbA1c levels in 8138 patients. Blood samples were collected using Potassium EDTA-containing vials and processed with an automated analyzer. Seasonal variations were explored using time series analysis. Results: Mean HbA1c levels peaked during the monsoon (June to September) and were lowest in autumn (October to November). Subgroup analysis revealed differences in patients with HbA1c values below and above 6.5 %. Those with controlled blood sugar showed higher levels in winter (December to February) and monsoon (June to September), while patients with HbA1c values ≥ 6.5 % exhibited significantly lower levels in monsoon (June to September) and autumn (October to November) compared to summer (March to May). Conclusion: In contrast to global trends, Indian patients demonstrated distinct seasonal variations in HbA1c levels. The highest levels during the monsoon (June to September) may be linked to reduced outdoor activity and dietary changes. The study emphasizes the need for tailored diabetes management considering seasonal influences. Further extensive, longitudinal studies across diverse Indian regions are recommended to comprehensively grasp the impact of seasonal changes on diabetes outcomes.

RESUMO

Aims and Objectives: Dry eye disease (DED) is a common condition that affects the quality of life of may individuals. This study aims to estimate the prevalence of DED and identify potential risk factors in adult patients seeking care at Lagos State University Teaching Hospital., Nigeria. Materials and Methods: This was a cross-sectional, hospital-based study that aimed to determine the prevalence of DED in type 2 diabetic and non-diabetic patients. A total of 200 adult participants-100 with type 2 diabetes and 100 non-diabetic patients, were recruited into the study. A symptom screening standard patient evaluation for dryness questionnaire was administered and a fluorescein break-up time test was done to diagnose DED. Results: The mean age was 61.4 years (±11.7 SD) and most were females (146, 72.86%). Using the standard patient evaluation for dryness questionnaire, 87.31% of the study participants had symptom(s) of DED. The proportion of DED in diabetics was 63.95% while in the non-diabetics was 68.37%, and this was significantly higher in the non-diabetic group (proportion difference of 16.47%, P = 0.006).The prevalence of DED as measured by the fluorescein break-up time was 55.81% (95% CI: 48.39-63.24). There was no significant difference in prevalence between diabetic and non-diabetic participants. Logistic regression analysis showed that increased duration of diabetes and age were significant predictors of DED in diabetic and non-diabetic groups, respectively. Conclusion: The prevalence of DED was high in our study population with increasing duration of diabetes in diabetics and older age in non-diabetics significantly associated with DED.

RESUMO

Introduction: Diabetes is a widespread chronic metabolic condition that has a significant negative influence on a person's sociopsychological, physical, and economic well-being. This study was designed to (1) measure the impact of oral health on quality of life (QoL) using the Oral Health Impact Profile-14 (OHIP-14) in association with other factors (age, gender, years of diabetes, level of education, smoking, presence of other conditions, oral complaints, and glycemic control) and (2) validate the Arabic version of the OHIP-14. Materials and Methods: Diabetic and healthy participants completed a two-part survey including demographic characteristics OHIP-14 questionnaire. Results: The sample consisted of 121 patients with type 2 diabetes mellitus and 146 healthy controls. Sociodemographic data, OHIP-14 questionnaires, and glycemic control data were collected. The data were statistically analyzed. The results showed that OHIP-14 was found to have sufficient reliability and validity in measuring life quality. Our study documented the effects of oral health complications on QoL among diabetics compared to controls. The type of diabetes had no effect on life quality. The highest OHIP-14 domain affected was functional limitation, while the lowest one was social handicap. Conclusion: It was concluded that diabetes has a negative effect on life quality. Diabetic patients have unsatisfactory oral health, which affects their QoL. The OHIP-14 is a reliable and valuable instrument to measure life quality.

RESUMO

Nerves in patients with diabetic neuropathy (DN) show increased susceptibility to local anesthetics, potentially requiring a decreased dose. We investigated whether the minimum effective anesthetic concentration (MEAC) of mepivacaine for successful axillary block is lower in patients with DN than in those without. This prospective observational study included patients with DN (n = 22) and without diabetes (n = 22) at a tertiary care center. Patients received an ultrasound-guided axillary block with 30 mL of mepivacaine for anesthesia. The mepivacaine concentration used in each patient was calculated using Dixon's up-and-down method. A block was considered successful if all four sensory nerves had a score of 1 or 2 within 30 min with no pain during surgery. The primary outcome was the MEAC of mepivacaine, and the secondary outcomes included the minimal nerve stimulation intensity for the musculocutaneous nerve and the occurrence of adverse events. The MEAC50 was 0.55% (95% CI 0.33-0.77%) in patients without diabetes and 0.58% (95% CI 0.39-0.77%) in patients with DN (p = 0.837). The MEAC90 was 0.98% (95% CI 0.54-1.42%) in patients without diabetes and 0.96% (95% CI 0.57-1.35%) in patients with DN (p = 0.949). The stimulation threshold for the musculocutaneous nerve was significantly different between groups (0.49 mA vs. 0.19 mA for patients with vs. without diabetes; p = 0.002). In conclusion, the MEAC of mepivacaine for a successful axillary block is not lower in patients with DN.

RESUMO

Continuous glucose monitoring (CGM) device adoption in non- and pre-diabetics for preventive healthcare has uncovered a paucity of benchmarking data on glycemic control and insulin resistance for the high-risk Indian/South Asian demographic. Furthermore, the correlational efficacy between digital applications-derived health scores and glycemic indices lacks clear supportive evidence. In this study, we acquired glycemic variability (GV) using the Ultrahuman (UH) M1 CGM, and activity metrics via the Fitbit wearable for Indians/South Asians with normal glucose control (non-diabetics) and those with pre-diabetes (N = 53 non-diabetics, 52 pre-diabetics) for 14 days. We examined whether CGM metrics could differentiate between the two groups, assessed the relationship of the UH metabolic score (MetSc) with clinical biomarkers of dysglycemia (OGTT, HbA1c) and insulin resistance (HOMA-IR); and tested which GV metrics maximally correlated with inflammation (Hs-CRP), stress (cortisol), sleep, step count and heart rate. We found significant inter-group differences for mean glucose levels, restricted time in range (70-110 mg/dL), and GV-by-SD, all of which improved across days. Inflammation was strongly linked with specific GV metrics in pre-diabetics, while sleep and activity correlated modestly in non-diabetics. Finally, MetSc displayed strong inverse relationships with insulin resistance and dysglycemia markers. These findings present initial guidance GV data of non- and pre-diabetic Indians and indicate that digitally-derived metabolic scores can positively influence glucose management.

RESUMO

Metabolic memory refers to the long-term effects of achieving early glycemic control and the adverse implications of high blood glucose levels, including the development and progression of diabetes complications. Our study aimed to investigate whether the phenomenon of metabolic memory plays a role in the immune profile of young patients with uncomplicated type 1 diabetes (T1D). The study group included 67 patients with uncomplicated type 1 diabetes with a mean age of 15.1 ± 2.3 years and a minimum disease duration of 1.2 years. The control group consisted of 27 healthy children and adolescents with a mean age of 15.1 ± 2.3 years. Patients were divided into three groups according to their HbA1c levels at the onset of T1D, and the average HbA1c levels after one and two years of disease duration. The subgroup A1 had the lowest initial HbA1c values, while the subgroup C had the highest initial HbA1c values. Cytokine levels (including TNF-α, IL-35, IL-4, IL-10, IL-18, and IL-12) were measured in all study participants. Our data analysis showed that subgroup A1 was characterized by significantly higher levels of IL-35 and IL-10 compared to all other groups, and significantly higher levels of IL-4 compared to group B. Additionally, a comparative analysis of cytokine levels between the groups of diabetic patients and healthy controls demonstrated that subgroup A1 had significantly higher levels of anti-inflammatory cytokines. The lipid profile was also significantly better in subgroup A1 compared to all other patient groups. Based on our findings, it appears that an inflammatory process, characterized by an imbalance between the pro- and anti-inflammatory cytokines, is associated with poor glycemic control at the onset of diabetes and during the first year of disease duration. These findings also suggest that both metabolic memory and inflammation contribute to the abnormal lipid profile in patients with type 1 diabetes.

RESUMO

INTRODUCTION: Parkinson's disease (PD) and type-2 diabetes (T2D) arguably share pathophysiologic mechanisms, resulting in a more severe phenotype and progression and diabetes is currently considered a risk factor of PD. Besides, research suggests antidiabetic therapies as potential disease-modifying strategies. The main aim was to assess the impact of a metformin-inclusive antidiabetic treatment on patient all-cause mortality. METHODS: A nested case-control prospective study including newly diagnosed PD patients reporting the onset of T2D within ±2 years from the onset of PD (n = 159) and matched (1:5; gender, year of PD onset and age at PD onset) non-diabetic cases (n = 795) followed until death or censoring. Patients on a metformin-inclusive treatment regimen were compared to those receiving other oral anti-diabetics (OADs). RESULTS: Among patients with T2D, 123 were treated with a drug regimen containing metformin (alone [65.0%] or in combination with other drugs [35.0%]) and 36 were prescribed other OADs. During a median PD duration of 96 months [IQR, 60-144], 171 patients died. Diabetes was not associated with reduced survival: fully-adjusted HR = 1.19 [95%CI, 0.81-1.76] (P = 0.37). After stratifying for T2D treatment, a metformin-inclusive regimen was not associated with increased risk of death (HR = 1.06 [95%CI, 0.61-1.84]; P = 0.83), while patients receiving other OADs had reduced survival (HR = 1.83 [95%CI, 1.01-3.32]; P = 0.034). CONCLUSIONS: Metformin use was not associated with increased risk of death in diabetic patients with PD reporting concomitant onset of the two diseases. Metformin appears to be a promising disease-modifying therapy given also the preclinical background, low cost and satisfactory safety and tolerability. Further studies are warranted to investigate its impact on disease progression.

RESUMO

BACKGROUND: Diabetes Mellitus (DM) is considered a chronic disease with numerous secondary complications that negatively affect the quality of life of patients. However, the specific, known and validated instruments for Brazilian Portuguese are too extensive, which often makes their use infeasible. OBJECTIVE: To validate the internal structure of the Brazilian version of the Diabetes Quality of Life (DQOL) measure. METHODOLOGY: Patients with DM type 1 or 2, between the ages of 18 and 76, were evaluated between April 2022 and May 2022. The survey was conducted online using the Google Forms platform. The original DQOL contains 46 multiple-choice questions organized into four domains. For structural validity, confirmatory factor analysis (CFA) was performed using RStudio software (Boston, MA, USA) with the packages lavaan and semPlot. RESULTS: A total of 354 subjects were evaluated. The 3-domain, 24-item version of the DQOL was the most adequate, with acceptable values for all fit indices (chi-square/GL < 3, TLI and CFI > 0.90, and RMSEA and SRMR < 0.08). CONCLUSION: The structure with three domains and 24 items is the most appropriate based on factor analysis. The Brazilian version of the DQOL with a structure of 3 domains and 24 items has adequate measurement properties that support its use in the clinical and scientific context in patients with DM.

RESUMO

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are currently available for the management of type 2 diabetes mellitus. SGLT2i acts by inhibiting renal SGLT2, thereby increasing glucosuria and lowering serum glucose. Recent trials are emerging supporting a role for SGLT2i irrespective of the diabetic status pointing towards that SGLT2i have other mechanisms of actions beyond blood sugar control. In this review, we will shed light on the role of this group of medications that act as SGLT2i in non-diabetics focusing on pre-clinical and clinical data highlighting the mechanism of renoprotection and effects of SGLT2i in the non-diabetic kidneys.

RESUMO

The molecular events of protein misfolding and self-aggregation of tau and amylin are associated with the progression of Alzheimer's and diabetes, respectively. Recent studies suggest that tau and amylin can form hetero-tau-amylin oligomers. Those hetero-oligomers are more neurotoxic than homo-tau oligomers. So far, the detailed interactions between the hetero-oligomers and the neuronal membrane are unknown. Using multiscale MD simulations, the lipid binding and protein folding behaviors of hetero-oligomers on asymmetric lipid nanodomains or raft membranes were examined. Our raft membranes contain phase-separated phosphatidylcholine (PC), cholesterol, and anionic phosphatidylserine (PS) or ganglioside (GM1) in one leaflet of the lipid bilayer. The hetero-oligomers bound more strongly to the PS and GM1 than other lipids via the hydrophobic and hydrophilic interactions, respectively, in the raft membranes. The hetero-tetramer disrupted the acyl chain orders of both PC and PS in the PS-containing raft membrane, but only the GM1 in the GM1-containing raft membrane as effectively as the homo-tau-tetramer. We discovered that the alpha-helical content in the heterodimer was greater than the sum of alpha-helical contents from isolated tau and amylin monomers on both raft membranes, indicative of a synergetic effect of tau-amylin interactions in surface-induced protein folding. Our results provide new molecular insights into understanding the cross-talk between Alzheimer's and diabetes.

RESUMO

BACKGROUND: Diabetes and hypertension are some of the most prevalent and costly chronic conditions in the United States. However, outcomes continue to lag behind targets, creating further risk of long-term complications, morbidity, and mortality for people living with these conditions. Furthermore, racial and ethnic disparities in glycemic and hypertension control persist. Flexible telehealth programs leveraging asynchronous care allow for increased provider access and more convenient follow-up, ultimately improving critical health outcomes across demographic groups. OBJECTIVE: We aim to evaluate the 12-month clinical outcomes of participants in the 9amHealth web-based clinic for diabetes and hypertension. We hypothesized that participation in the 9amHealth program would be associated with significant improvements in glycemic and blood pressure (BP) control across a diverse group of individuals. METHODS: We enrolled 95 patients in a completely web-based care clinic for diabetes and hypertension who received nutrition counseling, health coaching, and asynchronous physician consultations for medication prescribing. Patients received standard or cellular-connected glucose meters and BP cuffs in order to share data. Laboratory tests were completed either with at-home phlebotomy draws or a self-administered test kit. Patients' first and last hemoglobin A1c (HbA1c) and BP results over the 12-month period were compared, and analyses were repeated across race and ethnicity groups. RESULTS: Among all 95 patients, the average HbA1c decreased by -1.0 (from 8.2% to 7.2%; P<.001) over 12 months of program participation. In those with a baseline HbA1c >8%, the average HbA1c decreased by -2.1 (from 10.2% to 8.1%; P<.001), and in those with a baseline HbA1c >9%, the average HbA1c decreased by -2.8 (from 11% to 8.2%; P<.001). Among participants who identified as a race or ethnicity other than White, the HbA1c decreased by -1.2 (from 8.6% to 7.4%, P=.001). Further examination of subgroups confirmed HbA1c lowering within each race or ethnicity group. In the overall population, the average systolic BP decreased by 17.7 mm Hg (P=.006) and the average diastolic BP decreased by 14.3 mm Hg (P=.002). Among participants self-identifying as a race or ethnicity other than White, the results similarly showed a decrease in BP (average reduction in systolic BP of 10 mm Hg and in diastolic BP of 9 mm Hg). CONCLUSIONS: A fully web-based model leveraging all-asynchronous physician review and prescribing, combined with synchronous and asynchronous coaching and nutrition support, was associated with clinically meaningful improvement in HbA1c and BP control over a 12-month period among a diverse group of individuals. Further studies should prospectively evaluate the effectiveness of such models among larger populations, assess the longer-term sustainability of these outcomes, and explore financial models to make these types of programs broadly accessible.

RESUMO

A pandemia do novo coronavírus (covid-19) é um grave problema de saúde pública. Adicionalmente, a hiperglicemia na gestação (diabetes preexistente, diabetes diagnosticado pela primeira vez na gestação e diabetes mellitus gestacional) é uma das complicações maternas mais frequentes na população obstétrica. A sobreposição desses problemas pode refletir na saúde materna e fetal. Desse modo, o objetivo deste estudo é reunir evidências acerca da saúde materna de mulheres com hiperglicemia na gestação durante a pandemia de covid-19 no Brasil. Trata-se de uma revisão narrativa, em que a fonte de dados compreendeu artigos publicados até maio de 2023 nas bases de dados Medline, via PubMed, Lilacs e WHO COVID-19 Research Database. Foram listados 167 artigos e, após a aplicação dos critérios de elegibilidade, cinco estudos foram incluídos, compreendendo 1.469 gestantes e puérperas com diabetes mellitus gestacional ou diabetes preexistente. Quanto à saúde materna, os principais desfechos foram relacionados à infecção por covid-19, como gravidade da doença e risco de morte. Além disso, foi observada maior prevalência de transtornos mentais comuns, como ansiedade e depressão. Portanto, a saúde materna de mulheres com hiperglicemia na gestação foi impactada negativamente durante a pandemia de covid-19 no país.


The new coronavirus (COVID-19) pandemic is a major public health issue. Hyperglycemia during pregnancy (pre-existing diabetes, diabetes first diagnosed in pregnancy and gestational diabetes mellitus) is a frequent maternal complication in the obstetric population. Their overlap may impact maternal and fetal health. Thus, this narrative review gathered evidence on the maternal health of women with gestational hyperglycemia during the COVID-19 pandemic in Brazil. Articles published until May 2023 in the Medline (via PubMed), Lilacs and WHO COVID-19 Research Database online databases were eligible. Bibliographic search retrieved a total of 167 articles, of which five remained after applying the inclusion criteria, resulting in a sample of 1,469 pregnant and postpartum women with gestational diabetes or pre-existing diabetes. Regarding maternal health, the main outcomes were related to COVID-19 infection, such as disease severity and risk of death. Additionally, results showed a higher prevalence of common mental disorders such as anxiety and depression. In conclusion, the maternal health of women with gestational hyperglycemia was negatively impacted during the COVID-19 pandemic.

La superposición de estos problemas puede afectar la salud materna y fetal. Por lo tanto, el objetivo de este estudio es recopilar evidencia sobre la salud materna de las mujeres con hiperglucemia en el embarazo durante la pandemia de la COVID-19 en Brasil. Se trata de una revisión narrativa, y la fuente de datos comprendió artículos publicados hasta mayo de 2023 en las bases de datos MEDLINE vía PubMed, LILACS y WHO COVID-19 Research Database. Se enumeró un total de 167 artículos y, después de aplicar los criterios de elegibilidad, se incluyeron cinco estudios con 1.469 mujeres embarazadas y puérperas con diabetes gestacional o diabetes preexistente. En cuanto a la salud materna, los principales resultados se relacionaron con el contagio por COVID-19, como la gravedad de la enfermedad y el riesgo de muerte. Además, se observó una mayor prevalencia de trastornos mentales comunes, como la ansiedad y la depresión. Por lo tanto, la salud materna de las mujeres con hiperglucemia durante el embarazo se ha visto afectada negativamente durante la pandemia de la COVID-19 en Brasil.
