Biochemical markers and physiological parameters as indices for identifying patients at risk of developing pre-eclampsia

Migraine: Advances in the Pathogenesis and Treatment

This article presents a comprehensive review on migraine, a prevalent neurological disorder characterized by chronic headaches, by focusing on their pathogenesis and treatment advances. By examining molecular markers and leveraging imaging techniques, the research identifies key mechanisms and triggers in migraine pathology, thereby improving our understanding of its pathophysiology. Special emphasis is given to the role of calcitonin gene-related peptide (CGRP) in migraine development. CGRP not only contributes to symptoms but also represents a promising therapeutic target, with inhibitors showing effectiveness in migraine management. The article further explores traditional medical treatments, scrutinizing the mechanisms, benefits, and limitations of commonly prescribed medications. This provides a segue into an analysis of emerging therapeutic strategies and their potential to enhance migraine management. Finally, the paper delves into neuromodulation as an innovative treatment modality. Clinical studies indicating its effectiveness in migraine management are reviewed, and the advantages and limitations of this technique are discussed. In summary, the article aims to enhance the understanding of migraine pathogenesis and present novel therapeutic possibilities that could revolutionize patient care.

Sensitivity of uterine artery Doppler pulsatility index in screening for adverse pregnancy outcome in first and second trimesters

PURPOSE

In a poor resource country where screening for adverse pregnancy outcomes using maternal biomarkers seems unattainable, there is a need to search for credible alternatives. This study is, therefore, aimed at determining the sensitivity of uterine artery Doppler pulsatility index (UtAD-PI) in predicting pregnancy outcomes in the first and second trimesters and to establish any statistical difference in mean UtAD-PI in first and second trimesters screening of women with normal and abnormal pregnancy outcomes respectively.

METHODS

This clinical-based, longitudinal, and unpaired cohort study involved 500 pregnant women, who were screened for adverse outcomes using UtAD-PI and delivered in the hospital. These were divided into two groups, each having a training set and a test set. The training set was used to generate the receiver operator characteristic curve and cut-off point while the test set was used to test for sensitivity and specificity of the Ut-ADI in each trimester.

RESULTS

The sensitivity and specificity of UtAD-PI in first-trimester screening are 97% and 76.5% while second-trimester gave sensitivity and specificity of 57.5% and 63.3% respectively. The uterine artery Doppler pulsatility index shows statistically significant differences between normal pregnancy and pregnancy with adverse outcomes (p-value = 0.000).

CONCLUSION

The uterine artery Doppler pulsatility index is a good screening tool for adverse pregnancy outcomes. First-trimester screening of patients for adverse outcomes is more sensitive than the second-trimester screening using UtAD-PI. There is also a statistically significant difference between mean UtAD-PI between normal pregnancy and pregnancy with adverse pregnancy outcomes.

Spectrum of Factors Triggering Endothelial Dysfunction in PIH

INTRODUCTION

Pre-eclampsia (PE) is a major cause of maternal and fetal/neonatal mortality and morbidity. The aetiology and pathogenesis of PE is yet to be completely understood. Evidence shows that, Endothelial Dysfunction (ED) plays a pivotal role in the genesis of this multi-system disorder that develops in PE and eclampsia.

AIM

To determine the circulating levels of factors Malondialdehyde (MDA), Ferric Reducing Ability of Plasma-α (FRAP), Tumour Necrosis Factor (TNF-α), sFlt-1, VEGF, PlGF, Nitric Oxide (NO) that influence the ED.

MATERIALS AND METHODS

Study groups consisted of Normotensive pregnant women (N), preeclamptic women (PE) and eclamptic women (E) with 100 subjects in each group in the 3^rd trimester of pregnancy. They were investigated for MDA, FRAP, TNF-α, sFlt-1, VEGF, PlGF, NO. Statistical analysis was done using Analysis of Variance (ANOVA).

RESULTS

When compared to controls MDA, TNF-α, sFlt-1 levels were found to be significantly high and FRAP, VEGF, PIGF and NO levels were significantly low in PE and E group. E showed a significantly high level of MDA, TNF-α, sFlt-1 and low levels of FRAP, VEGF, PIGF, NO when compared to PE group.

CONCLUSION

Our study substantiated the fact, that oxidative stress, imbalance between anti-angiogenic factors and pro- angiogenic factors exists in Pregnancy Induced Hypertension (PIH) condition. This imbalance is directly related to the ED, the hallmark of PE. So oxidative stress, VEGF, PlGF and sFlt-1 can be used as markers to analyze the onset and progression of the disease.

PLATELET COUNT IN WOMEN WITH PREGNANCY INDUCED HYPERTENSION IN UNIVERSITY HOSPITAL CENTER OF MOTHER AND CHILD HEALTHCARE "KOçO GLIOZHENI", TIRANA, ALBANIA

INTRODUCTION

One of the most common and potential life threatening complications of pregnancy is pregnancy induced hypertension. This cross-sectional study aimed to investigate the relationship between platelet count and pregnancy induced hypertension.

MATERIAL AND METHODS

Twenty (20) patients (subjects) and twenty (20) healthy pregnant women (control) visiting the Obstetrics and Gynecology Hospital University of "Koço Gliozheni" Tirana Albania were registered in the study and followed during their pregnancy. Both, subjects and control participants were subject to platelet count manually performed using standard methods on.

RESULTS

The mean platelet count of the control group (38448±235500) was significantly higher than that of the subject group (217050±50780.7) (p<0.03). In the first and second trimester was more prevalent low platelet counting with the mean platelet count (107 ±57.3) and (101 ±63.4), respectively. The mean age at marriage in subjects with PIH was found to be with low platelet count. Regular monitoring of platelet counts in women with Pregnancy Induced Hypertension must be subject of the management protocols.

Community perceptions of pre-eclampsia and eclampsia in Ogun State, Nigeria: a qualitative study

BACKGROUND

Pre-eclampsia is a complication of pregnancy responsible for high rates of morbidity and mortality, particularly in sub-Saharan Africa. When undetected or poorly managed, it may progress to eclampsia which further worsens the prognosis. While most studies examining pre-eclampsia have used a bio-medical model, this study recognizes the role of the socio-cultural environment, in order to understand perceptions of pre-eclampsia within the community.

METHODS

The study was conducted in Ogun State, Nigeria in 2011-2012. Data were obtained through twenty-eight focus group discussions; seven with pregnant women (N = 80), eight with new mothers (N = 95), three with male decision-makers (N = 35), six with community leaders (N = 68), and three with traditional birth attendants (N = 36). Interviews were also conducted with the heads of the local traditional birth attendants (N = 4) and with community leaders (N = 5). Data were transcribed verbatim and analysed in NVivo 10 software.

RESULTS

There was no terminology reportedly used for pre-eclampsia in the native language - Yoruba; however, hypertension has several terms independent of pregnancy status. Generally, 'gìrì âlábôyún' describes seizures specific to pregnancy. The cause of hypertension in pregnancy was thought to be due to depressive thoughts as a result of marital conflict and financial worries, while seizures in pregnancy were perceived to result from prolonged exposure to cold. There seemed to be no traditional treatment for hypertension. However for seizures the use of herbs, concoctions, incisions, and topical application of black soap were widespread.

CONCLUSION

This study illustrates that knowledge of pre-eclampsia and eclampsia are limited amongst communities of Ogun State, Nigeria. Findings reveal that pre-eclampsia was perceived as a stress-induced condition, while eclampsia was perceived as a product of prolonged exposure to cold. Thus, heat-related local medicines and herbal concoctions were the treatment options. Perceptions anchored on cultural values and lack of adequate and focused public health awareness is a major constraint to knowledge of the aetiology and treatment of the conditions. A holistic approach is recommended for sensitization at the community level and the need to change the community perceptions of pre-eclampsia remains a challenge.

Public health perspectives of preeclampsia in developing countries: implication for health system strengthening

OBJECTIVES

Review of public health perspectives of preeclampsia in developing countries and implications for health system strengthening.

METHODS

Literature from Pubmed (MEDLINE), AJOL, Google Scholar, and Cochrane database were reviewed.

RESULTS

The prevalence of preeclampsia in developing countries ranges from 1.8% to 16.7%. Many challenges exist in the prediction, prevention, and management of preeclampsia. Promising prophylactic measures like low-dose aspirin and calcium supplementation need further evidence before recommendation for use in developing countries. Treatment remains prenatal care, timely diagnosis, proper management, and timely delivery. Prevailing household, community, and health system factors limiting effective control of preeclampsia in these countries were identified, and strategies to strengthen health systems were highlighted.

CONCLUSION

Overcoming the prevailing challenges in the control of preeclampsia in developing countries hinges on the ability of health care systems to identify and manage women at high risk.

Biomarkers in migraine: their promise, problems, and practical applications

Biomarkers are physical signs or laboratory measurements that "occur in association with a pathological process and have putative diagnostic and/or prognostic utility." Biomarkers hold considerable promise for understanding and intervening in the disease process of migraine. They may permit recognition of individuals at risk of developing migraine, improve the timing, accuracy, and precision of migraine diagnosis, and serve as indicators of treatment response and disease progression. Furthermore, they hold great promise for research. At the same time, there are important limitations to the use of biomarkers in migraine, including problems with validity, reliability, accuracy, and precision. Legal, ethical, and cost considerations are also important. This review describes the potential uses and limitations of biomarkers in migraine diagnosis, treatment, and research.

Metabolic fingerprinting in disease diagnosis: biomedical applications of infrared and Raman spectroscopy

The ability to diagnose the early onset of disease, rapidly, non-invasively and unequivocally has multiple benefits. These include the early intervention of therapeutic strategies leading to a reduction in morbidity and mortality, and the releasing of economic resources within overburdened health care systems. Some of the routine clinical tests currently in use are known to be unsuitable or unreliable. In addition, these often rely on single disease markers which are inappropriate when multiple factors are involved. Many diseases are a result of metabolic disorders, therefore it is logical to measure metabolism directly. One of the strategies employed by the emergent science of metabolomics is metabolic fingerprinting; which involves rapid, high-throughput global analysis to discriminate between samples of different biological status or origin. This review focuses on a selective number of recent studies where metabolic fingerprinting has been forwarded as a potential tool for disease diagnosis using infrared and Raman spectroscopies.
