COPD and low plasma vitamin D levels: Correlation or causality?

Published on: 27th October, 2018

OCLC Number/Unique Identifier: 7905962979

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death and its prevalence and incidence is also related to smoking behavior [1]. COPD is still a chronic inflammatory and progressive disease caused by multifactorial agents including environmental pollutants [2]. Besides that, it is emerging that endogenous epigenetic factors induced by lifestyle and environment [3] could play a role in the etiopathogenesis of the disease [4]. In the last years, several authors suggested that low vitamin D levels seem to be related with the increase of COPD manifestations [5]. Moreover, a multicentre, double-blind, randomised controlled trial documented that vitamin D supplementation protects against moderate or severe exacerbation of the disease, but not by upper respiratory infections [6]. However, low levels of vitamin D can be extended to many other diseases, including multiple sclerosis, diabetes, colon rectal cancer, headache or drug use [7-11]. Moreover, it is also important to remember that Vitamin D deficiency is common in high latitude regions, such as northern Europe, New Zealand, northern USA, and Canada where weaker ultraviolet B rays is not able to produce enough vitamin D. Finally, methodological factors (using low sensitivity methods) could contribute to misleading evaluation of circulating vitamin D levels. In any case, here we shall remind that vitamin D has a fundamental role in immunity [12]. In particular, it has been reported that vitamin D is able to shift the pro-inflammatory T-helper cell 1 to anti-inflammatory T-helper cell 2 [13]. Therefore, benefits of vitamin D supplementation in chronic diseases which directly or indirectly affect immune system are obvious. Today, the burden of COPD in never smokers is higher than previously believed. Therefore, more research is needed to unravel the characteristics of non-smokers COPD [1]. Notably, vitamin D levels are reported to be significantly lower in smoker’ssubjects than in non-smokers ones [14]. Therefore, low plasma vitamin D levels in COPD seems to be more a causality than a correlation.

Natural color performance from nine species origins of lowland wood wastes

Published on: 15th March, 2023

In the past, natural pigments derived from plant-biomass wastes had been widely used for coloring purposes (e.g. fabrics/batik), before finally getting pushed aside by the imported synthetic/inorganic pigments. Thorough attempts to revive the use of such natural pigments then deserve carrying out. Relevantly, conducting storage of liquid/wet or dry natural coloring pigments, extracted from wood wastes; and use of fixatives for batik fabrics intended to impart fabric-color variations. Wood wastes (i.e. leaves and barks) were obtained from nine plant species (Acacia mangium Willd, Avicenia marina L, Caesalpinia sappan L, Ceriop tagal Perr. CB. Rob, Pelthophorum ferruginum Benth, Rhyzophora mucronata Lamk, Tectona grandis Linn.f., Terminalia catappa L and Xylocarpus granatum KD Koenig.), prevalently growing on plain/lowland areas; and their wood portions commonly utilized by wood industries, which generate similar wastes enormously. The pigments in liquid/wet and then in dry forms were produced from those wastes. The production process of pigments adopted traditions by local batik crafters in Bogor. Variations occurring in fabric colors could be due to fixatives, i.e. lime (CaCO3), ferrous sulphate/tunjung (FeSO4); and various wastes. Six-month storage insignificantly changed the coloring qualities of natural coloring pigments applied to fabrics, compared to those of corresponding initially produced pigments. Leaf wastes always contained green-colored compounds, while bark wastes appeared aptly brownish in color. Color performances of bark extracts at fabrics with ferro-sulfat fixative brought about strong grey colors, and with lime fixative produced brown colors. Coloring of fabrics using leaf waste extracts with ferro-sulfat fixative aptly exhibited greenish grey; while with lime fixative became reddish brown. Testing results on the leaching resistance of pigment-colored and fixative-treated fabrics against rubbing and exposure to sunlight revealed a very good category (4-5), but against detergent, washing was very low (2-3).

Hypo-glycaemia and Associated Factors among Type 1 Diabetes Mellitus Patients Attending the Outpatient Clinics of Debre-tabor Compressive and Specialized Hospital, South Gondar Zone, North West Ethiopia: A Cross-sectional Study

Published on: 15th April, 2024

Introduction: Hypoglycemia affects patient safety and glycemic control during insulin treatment of both type 1 (T1DM) and type 2 diabetes mellitus (T2DM). It is still a major clinical problem in the treatment of type 1 diabetes that impairs metabolic control. This study aimed to assess hypoglycemia and associated factors among type 1 diabetes mellitus patients attending the outpatient clinics of Debra–Tabor Comprehensive and Specialized Hospital, in 2021.Method: institutional-based cross-sectional study design was conducted among 204 selected type I DM, from June 1/2021 to August 30/2021. The study participants were selected by systematic sampling method from monthly follow-up lists and lists of registration. Data were cleaned and entered into Epi Data and then exported into SPSS version 20 for analysis. Data were presented with texts, graphs, diagrams, and tables but an analytic form of findings will be presented by text form of the odds ratio. Bivariable and multivariable binary logistic regression models were fitted to identify factors associated with hypoglycemia p – value < 0.05 was considered statistically significant and reported as a 95% confidence interval (CI).Results: A total of 204 participants participated with a response rate of 100%, and prevalence of self-reported hypoglycemia was 88.7% (95%, CI: 83.8-92.6) and the prevalence of hypoglycemia was significantly associated with occupation [AOR: 4.01 (95% CI:1.86-9.35)], higher educational status [AOR: 2.13 (95% CI:1.92-13.15)], diabetic duration < 1 [AOR: 3.80 (95% CI:1.32-9.28)], poor knowledge [AOR: 4.91 (95% CI:1.09-11.06)] and favorable attitude [AOR: 5.86 (1.10-6.07)]. The current study revealed that the knowledge, attitude, and practice of respondents were 81.9% (95%, CI, 76-86.8), 73% (95% CI, 66.7-78.9), and 91.2% (95% CI, 86.8-94.6) respectively.Conclusion and recommendation: Hypoglycemia was highly prevalent among diabetic patients treated at Debra-Tabor Comprehensive and Specialized Referral Hospital. To reduce the higher prevalence of hypoglycemia the health professionals working in the hospital had better provide appropriate patient advice about, BGL monitoring, medication adherence, self-injection as well as oral hypoglycemic agent administrations.

Published on: 20th January, 2017

OCLC Number/Unique Identifier: 7286426157

Micronodular thymoma is a rare subtype of thymoma with less than 20 cases published in the English literature. These tumours have been reported with thymoma or thymic cyst. The authors describe a new case of micronodular thymoma in a 68-year-old-patient which is well documented and particular by its cystic degeneration which hasn’t been described yet. Micronodular thymoma is a rare variant of thymoma with a challenging diagnosis. Clinicians must be aware of this entity in order not to confuse it with a thymic cyst.

Tumours of the Uterine Corpus: A Histopathological and Prognostic Evaluation Preliminary of 429 Patients

Published on: 30th January, 2017

OCLC Number/Unique Identifier: 7286353787

A histopathological review preliminary of 429 patients diagnosed with tumours of the uterine corpus (TUC) cancer between 1984- 2010 in the Vigo University Hospital Complex (Spain) were evaluated prospectively for over 5 years. Of these 403 (93.9%) were epithelial tumours: 355 (82.7%) were adenocarcinomas of the endometrioid type, 5 (1.1%) mucinous adenocarcinoma, 10 (2.3%) serous adenocarcinoma, 17 (3.9%) clear cell carcinomas, 11 (2.5%) mixed adenocarcinoma, 4 (0.9%) undifferentiated carcinomas and 1 (0.2%) squamous cell carcinomas. A total 20 (4, 6%) were mesenchymal tumours: 4 (0.9%) endometrial stromal sarcoma, 7 (1.6%) Leiomyosarcoma, 9 (2%) Mixed endometrial stromal and smooth muscle tumour. A total 1 (0.2%) were mixed epithelial and mesenchymal tumours: (0.2%) Adenosarcoma 1. And 5 (1.1%) were Metastases from extragenital primary tumour (3 carcinomas of the breast, 1 stomach and 1 colon). The mean age at diagnosis from total series were 65, 4 years (range 28-101 years). Age was clearly related to histologic type: Endometrial stromal sarcoma 46.0 years, Leiomyosarcomas 57.1 years, Adenocarcinomas of the endometrioid type 65.4 years, Clear cell carcinomas 70.1 years and mixed endometrial stromal and smooth muscle tumours 71.2 years. Five-year disease-free survival rates for the entire group were: Endometrial stromal sarcoma 50%, Leiomyosarcomas 28.6%, Adenocarcinomas of the endometrioid type 83.7%, Clear cell carcinomas 64.7% and mixed endometrial stromal and smooth muscle tumours 44.4%. The 5-year disease-free survival rates of patients with Adenocarcinomas of the endometrioid type tumors were 91.4% for grade 1 tumors, 77.5% for grade 2, and 72.7% for grade 3. In conclusion, we describe 5-year histological and disease-free survival data from a series of 429 patients with TUC, observing similar percentages to those described in the medical literature. The only difference we find with other published series is a slightly lower percentage of serous carcinomas (ESC) that the Western countries but similar to the 3% of all ESC in Japan. Our investigation is focus at the moment on construct genealogical trees for the possible identification of hereditary syndromes and to carry out germline mutation analysis.

Is It Possible to End Female Circumcision in Africa?

Published on: 22nd March, 2018

OCLC Number/Unique Identifier: 7877963713

Female genital mutilation / cutting remains a widespread practice throughout Africa. There has been a worldwide effort to do away with FMG/C, but tensions exist between those who aim to abolish FGM/C and those who desire to perpetuate the tradition. While many Western and African experts and organizations agree on the health risks and human rights concerns with FGM/C, others fear that Westerners are imposing their ideas and lack of cultural understanding, trying to eliminate a practice central to the identity of many Africans. The issue must be approached respectfully and collaboratively, with great effort on the part of Westerners to understand the cultural context and rationale of this tradition. Ultimately, if FGM/C is to be eradicated in the foreseeable future, whole African communities and international support agencies must be engaged and empowered to collectively evaluate the implications of the practice and accelerate its demise.

Advances in Physiological Research: Consideration on Arterial Hypercapnia in Acute Cardiogenic Pulmonary Edema (ACPE)

Published on: 24th October, 2024

The causes of hypercapnia in Acute Cardiogenic Pulmonary Edema are still unknown. Our hypothesis recognizes an alteration of the ventilation-perfusion ratio in the apical areas of the lung as the major cause. The redistribution of blood to the apical lung zone in hypertensive pulmonary circulation determines an excess of perfusion compared to ventilation and consequently hypercapnia. Our suggestion might be in favor of Bilevel-PAP over Continuous Positive Airway Pressure (CPAP) as the first line of therapy.

Screening of Gestational diabetes mellitus

Published on: 4th April, 2018

OCLC Number/Unique Identifier: 7586666202

Gestational diabetes mellitus is becoming a very common medical disorder associated with pregnancy especially so in the Middle East and more so in Saudi Arabia, thus putting the women and fetuses at an increased risk of maternal and neonatal morbidity and mortality. Screening for Gestational diabetes mellitus was recommended because of its asymptomatic nature and good proportion of patients with no classic risk factors. We recommended universal screening because of the beneficial effect of screening, diagnosis and subsequent treatment. The most recent study done in Security Forces Hospital showed a significant decrease in morbidity and mortality with application of the new values of screening, in spite of the increase of incidence of Gestational diabetes mellitus from 14.5 % in 2005 study, to 23.9 % in the recent study in 2015. Objectives: To highlight and determine the best screening method values of FBS and 2hrspp used to diagnose gestational diabetes mellitus. Maternal & neonatal out come and associated risks for patients who had Gestational diabetes mellitus, where scrutinized. The study was done in the period from June 1st 2013-31 of May 2014. Design: Retrospective cohort study. Setting: Tertiary centre (Security Forces hospital _Riyadh_Saudi Arabia). Patients: Out of 6849 patients who had their delivery in Security Forces Hospital between June 2013 and May 2014 (one year), 6340 patients (92.5 %) were screened for gestational diabetes mellitus, and out of these 1516 patients (23.9 %) were labeled as Gestational diabetes mellitus after exclusion of cases of IDDM and NIDDM. Main outcome measured: The purpose of this study is to advise on using new values for diagnosis of gestational diabetes and to assess the outcome of pregnancy after new values are implemented in security forces hospital for diagnosis. The outcome included ages of mothers, parities, number of abortions, associated medical disorders, and estimated blood loss. Control methods were also reviewed, gestational age of induction of labor. Associated intrapartum complications as well as fetal outcome were also reviewed. The weight of babies, congenital abnormalities, admission to neonatal intensive care unit were also studied. The different values used , and percentages of diagnosed values of last 3 studies done in Security Forces Hospital in comparison to the most recent study with new values(2014-2015) as shown in table 11. Results: The incidence of gestational diabetes mellitus increased from 14.5 % in the year 2003 - 2004 to reach 23.9 % in 2014, in the same institute (Security Forces Hospital), where the study was done using different values. In our study in Security Forces Hospital we recorded a significant decrease in morbidity and mortality on applying the new values. A significant reduction in the number of expired babies of mothers who were diagnosed as gestational diabetes with new values with a decrease from 5.6 % in previous years studied to reach 1.5 % in 2014, reflecting the effective control and the good catch for the new values. Conclusion: Universal screening, with whatever values to blood sugar used, is a better method screening than the selective one: Using 75 gram of Oral Glucose Tolerance Test proved to be cost effective, easily accessible, and with good pickup rate of up to 93 % of patients in Security Forces Hospital. Recommendations: To continue using the new values that will be universally implemented, with long term follow-up of mothers and newborn.
