Introduction Hypocalcaemia in pregnancy remains a major health issue, particularly in the developing world where daily calcium intakes are suboptimal. This electrolyte imbalance can lead to severe maternofoetal and childhood consequences. Calcium supplementation, amongst others, contributes significantly to meeting calcium demands in pregnancy. With ionised calcaemia as the gold standard for diagnosis, total calcaemia and albumin-corrected calcaemia in other pathological states have been found to overestimate the burden of hypocalcaemia. The main objectives of this study are to describe the blood calcium level (total, albumin corrected, and ionised calcaemia) and associated maternofoetal outcomes while identifying determinants of calcium supplementation and ionised hypocalcaemia. This study will also evaluate the sensitivity and specificity of albumin corrected calcaemia as a diagnostic tool for hypocalcaemia (ionised calcaemia as the gold standard) among pregnant women in the Nkongsamba Regional Hospital, Cameroon. Methods Our study will target a total of 1067 term pregnant women who shall be included consecutively into the study as they arrive the maternity of the Nkongsamba Regional Hospital for their last antenatal care visit. Data shall be collected using a semi-structured interview-administered questionnaire and blood samples collected for total plasma calcium, albumin and serum ionized calcium assays. Additional data will be collected at birth (maternal and foetal variables; foetal outcomes evaluated as secondary outcomes). Total calcaemia and albuminemia shall be measured by atomic absorption spectrophotometry, while ionised calcaemia will be measured by ion-selective electrode potentiometry(using MSLEA15-H electrolyte analyzer) per standard BIOLABO and MSLEA15 protocols, respectively. Data will be analysed using the statistical softwares epi-Info version 7.2.2.16 and STATA version 16. Expected research outcome This study will present a more precise estimate of the burden of hypocalcaemia in late pregnancy as well as identify and analyse the different factors associated with calcium supplementation and ionised hypocalcaemia among term pregnant women in a developing world setting. Maternofoetal outcomes associated with hypocalcaemia will be determined as well as the sensitivity and specificity of total and albumin-corrected calcaemia in diagnosing hypocalcaemia. Our findings will contribute significantly to designing or strengthening interventions to control this electrolyte imbalance.
Heavy metals and metalloids are dangerous because they have the tendency to bioaccumulate in biological organisms over a period of time. However, it is conceived that a number of phytochemical agents as well microorganism can act as heavy metal removing agent both from human beings and the environment surrounding. For instance, microbes are used for the removal of heavy metals from the water bodies including bacteria, fungi, algae and yeast. This review shows that bacteria can play an important role in understanding the uptake and potential removal behaviour of heavy metal ions. The bacteria are chosen based on their resistance to heavy metals (incl. their toxicities) and capacity of adsorbing them. Due to specifi c resistance transfer factors, cell impermeability is drastically inhibited by several ion (i.e. mercury, cadmium, cobalt, copper, arsenic) forms. Between these elements, free-ion cadmium and copper concentrations in the biological medium provide more accurate determination of metal concentrations that affect the bacteria, than with most of the other existing media. Metal toxicity is usually assessed by using appropriate metal ion chelators and adjusting pH factor. Bacteria and metals in the ecosystem can form synergistic or antagonistic relationships, supplying each other with nutrients or energy sources, or producing toxins to reduce growth and competition for limiting nutritional elements. Thus, this relation may present a more sustainable approach for the restoration of contaminated sources.
Farmers are concerned in the chemical supply chain (manufacturers, vendors, workers, and consumers) of the agricultural products through their understandings of the safety information (i.e. reading labels such as skull and crossbones symbols, volatile organic compound logo or the fish and tree symbol) and the factors influence misuse of irrigation and disposal behavior. Having recognized a methodological gap, this contribution was intended to investigate qualitatively (textural analysis) the determinants of the use behavior (UB) of farmers irrigating their lands by the recycled industrial wastewater (RIWW) (Aljerf, 2018) [1] using the exploratory investigation based on the single embedded case design. Such combined analytical methods enabled us to achieve both detailed insights into perceptions, behaviors, and an objective understanding of the prevailing opinions that occurred within and between the focus farmers group׳ discussions related around awareness, trust, access and disposal actions within the supply chain. Using the snowball sampling approach, verbal data were collected from 55 Syrian farmers. 5 × 11,000 US gallons (43,900 L) of the RIWW were delivered to each farmer upon request between May and October 2017. After a month of each distribution, the participant farmer was interviewed. To increase the validity of the data, method triangulation was implemented which encompassed participant observation, group debates, and unstructured interviews. The hermeneutic units were analyzed using the pattern-matching method in the Atlas.ti software (version 6.0.15) and the grounded concepts (determinants) were investigated to establish the hypothetical framework at three levels: intrapersonal, interpersonal, and institutional.
Oral diseases associated with systematic diseases as metabolic and vasculitic have been included in this paper. This will enhance our understanding of the salivary function in promoting healthy oral condition. The study investigates the effects of type I and type II diabetes mellitus in well-controlled diabetic patients, in addition to Behçet disease (BD) on saliva flow rate (SFR), pH, the decay, missing, and filled tooth (DMFT) index, glucose, and major earth-alkaline ions (Ca2+ and Mg2+) compared to healthy males and age-matched controls. Saliva samples were collected from 1403 male human subjects, distributed on 7 levels including 3 control groups, and analyzed. The symptoms and clinical observations were enrolled. A preprandial salivary glucose has illustrated statistically strong significant and positive correlations with HbA1c and blood glucose levels. TIDM saliva showed lower pH, SFR, and Ca2+ but higher Mg2+, caries risk, and poor metabolic control. These led to dysfunction of secretory capacity of salivary glands. TIIDM proved higher SFR, DMFT, and glucose than TIDM patients. DM oral calcium has decreased by age while magnesium sharply slopes at seniority. BD oral fluid is associated with lower glucose and minerals but noticeably with both higher pH and DMFT.
Background and aims: Down's syndrome patients are suffering from such gastrointestinal and metabolic complications which affect their prolongation for survival and this could be attributed to the malnutrition system. To reduce the risk factors for mortality, the paper has focused on the assessment of the socioeconomic, clinical, physical, biophysiological, and biochemical characteristics of them which can be affected by the type of nutrition system, toxicity, and ecological footprint.Methods: Patients were males with trisomy 21 diagnosed by karyotype test and assessed by clinical examinations. The clinical observations, medical interventions, and oral diseases associated with DS have been defined and oral treatment is explored. Samples collected from different biofluids. The physicochemical analyses of the biomatrix samples were performed and these properties had compared to findings of healthy males and age-matched controls. In specific, trace elements which could be originated from environmental resources were assessed in saliva, blood, urine, and hair.Results: Duraphat application was proved effective for their oral treatment and saliva was the optimum biomarker for detecting malnutrition. The patients were hypersensitive to Cu while the Mn content in blood and hair was considered an expression to the degree of epileptic condition and chronic seizure development. The ecological footprint was 5.6 gha and carbon footprint was recognised in food poverty habits. These can be reduced by eating more plant-based proteins and fibre-rich foods with low saturated fats and sodium.Conclusions: The current findings provide an up-to-date reference for expected developmental outcomes in children with DS in terms of biophysicochemistry. The genetically sensitive intervention is affected by heredity factor and sensitivity to toxics. Down's syndrome is encouraged to live green-hipster life. Besides, doctors are recommended to order the physicochemical analyses for early detection of this special intervention.WHO Clinical Trial Registry: Study ID number: DRKS00014074 Title page of the study: Down's syndrome in children males – biochemical characterisations in different media using non-randomised trial and systematic study Website of Clinical Trial Registry: http://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00014074
