Prophylactic use of chlorpromazine to improve survival of random skin flaps in pigs

On the basis of earlier success in rat studies, chlorpromazine was evaluated as a probable agent for improving survival of random skin flaps in pigs. The aim was to exclude the possibility that the effect of the chlorpromazine is species specific and to find out if it is dose dependent. One hundred and five dorsally-based 12×4 cm flaps were raised unilaterally on the backs of 15 pigs. The animals were divided into three groups using 15 mg/kg chlorpromazine, 7.5 mg/kg chlorpromazine, and a saline-treated control group. Flaps in the control group averaged 40.57±3.17% necrosis, while flaps in the 15 mg/kg and 7.5 mg/kg chlorpromazine-treated groups averaged 31.53±4.77% and 11.47±2.22% necrosis respectively. These results demonstrate dose dependent beneficial affects of chlorpromazine and the survival of random skin flaps in the pig. Although ideal dose levels are still to be determined, flap survival improved with the prophylactic use of chlorpromazine at the lower 7.5 mg/kg dosage.     

Comparison of positive allergy skin tests among asthmatic children from rural and urban areas living within small geographic area.

BACKGROUND: Evidence of increased asthma and allergic response among urban versus rural residents has been reported. OBJECTIVE: To evaluate the prevalence of allergic response among asthmatic children from urban and rural areas living within close proximity. METHODS: In all, 448 asthmatic children from urban (363) and rural (85) areas were studied. The study group consisted of 234 9-year-olds and 214 12-year-olds. A health questionnaire was completed on each child who subsequently underwent allergic skin prick tests (SPTs). RESULTS: There was significantly more positive SPT response to house-dust mite, mold, cat, and cypress among asthmatic children from urban areas compared with children living in rural areas: 58.3% versus 37.6%, 46.1% versus 31.8%, 17.45 versus 5.9%, and 26.2% versus 15.3%, respectively. Positive SPT for indoor allergens were significantly greater among asthmatic urban residents than asthmatic rural residents: 63.3% versus 45.5%, respectively (P < 0.02). Positive SPT response to all the allergens checked was higher among the 12-year-old age group when compared with the 9-year-olds, 34.6% versus 22.7%, respectively (P = 0.05). CONCLUSIONS: Allergic response measured by SPT is significantly more common among asthmatic children from urban areas as opposed to rural, even though both areas are within small distance of one another. Further, asthmatic children living in urban areas demonstrated more allergic response to both indoor and outdoor allergens. The allergic response tends to increase with increased age in both urban and rural asthmatic children.     

Skin injury following contact with a complex amine

Eight patients with skin damage due to contact with an amine are described. The material is used in the potash industry under the commercial name of Armine to prevent bosselation. Although it is considered to be a strong base, no deep burns were encountered. The reaction to this material initially resembled a dermatitis; later the wound developed the typical appearance of a burn. In addition to the common conservative treatment, antihistamine drugs were used. When a true allergic reaction was suspected steroids were added to the regimen.     

The role of drug delivery systems in health care: the case of self- medication

Up to 80 % of illness episodes are first defined, diagnosed and treated at the household-level. In the developing world especially, approximately half the population has no access to public health services. It is obvious then that other sources of care will be used. We examined the availability of proprietary drugs in communities, and the extent and reasons for their use in the treatment of childhood malaria on the Kenyan Coast. Retail outlets are extensively used as the first tier of health care for illnesses considered to be mild or mundane. However, the wide range, types and formulations of over-the- counter (OTC) drugs including antimalarials available in these retail outlets constitute a major health hazard. Yet, both users and proprietors of retail outlets know little or nothing about the drugs and thus use or sell them inappropriately. Even, children are treated promptly by purchase of OTC drugs. The policy implications of these findings are discussed.

Mg2+ Transporters in Digestive Cancers

Despite magnesium (Mg²⁺) representing the second most abundant cation in the cell, its role in cellular physiology and pathology is far from being elucidated. Mg²⁺ homeostasis is regulated by Mg²⁺ transporters including Mitochondrial RNA Splicing Protein 2 (MRS2), Transient Receptor Potential Cation Channel Subfamily M, Member 6/7 (TRPM6/7), Magnesium Transporter 1 (MAGT1), Solute Carrier Family 41 Member 1 (SCL41A1), and Cyclin and CBS Domain Divalent Metal Cation Transport Mediator (CNNM) proteins. Recent data show that Mg²⁺ transporters may regulate several cancer cell hallmarks. In this review, we describe the expression of Mg²⁺ transporters in digestive cancers, the most common and deadliest malignancies worldwide. Moreover, Mg²⁺ transporters’ expression, correlation and impact on patient overall and disease-free survival is analyzed using Genotype Tissue Expression (GTEx) and The Cancer Genome Atlas (TCGA) datasets. Finally, we discuss the role of these Mg²⁺ transporters in the regulation of cancer cell fates and oncogenic signaling pathways.     

A randomized,double-blind placebo-controlled add-on trial to assess the efficacy,safety, and anti-atherogenic effect of spirulina platensis in patients with inadequately controlled type 2 diabetes mellitus

The efficacy of spirulina platensis (S. platensis) as an add-on therapy to metformin and its effect on atherogenic keys in patients with uncontrolled Type 2 Diabetes Mellitus (T2DM) was evaluated. Sixty patients were randomly assigned to S. platensis (2 g/day) or placebo group for three months while continuing metformin as their usual treatment. The efficacy of S. platensis was determined using the pre- and post-intervention HbA1c levels (primary outcome) as well as tracking FBS and lipid profiles levels (TC, LDL-C, TG, and HDL-C) as secondary outcomes at the different treatment time points (0,30,60,90 days). During the three–month intervention period, supplementation with S. platensis resulted in a significant lowering of HbA1c (↓1.43, p < 0.001) and FBS (↓ 24.94 mg/dL, p < 001) levels. Mean TG in the intervention group was found to be significantly lower in the intervention group than in controls (p < 0.001). Total cholesterol (TC) and its fraction, LDL-C, exhibited a fall (↓41.36 mg/dL and ↓38.4 mg/dL, respectively; p < 0.001) coupled with a marginal increase in the level of HDL-C (↑3 mg/dL; p < 0.001). Add-on therapy with S. platensis was superior to metformin regarding long-term glucose regulation and controlling blood glucose levels of subjects with T2DM. Also, as a functional supplement, S. platensis has a beneficial effect on atherogenic keys (TG and HDL-C) with no adverse events.     

Cultivating a culture of research in nursing through a journal club for leaders: A pilot study

Aim

To describe whether an action learning‐inspired journal club for nurse leaders can develop the leaders' self‐perceived competences to support a research culture in clinical nursing practice.

Background

Development of clinical research capacity and nurse leaders with the requisite competences are key factors in evidence‐based health care practice. This study describes how nurse leaders at a large regional hospital took part in a journal club for nurse leaders, with a view to developing their competences to support a nursing research culture in their departments.

Methods

A pilot study using a multimethod approach to evaluate the journal club for nurse leaders. Four nurse leaders participated in the journal club for nurse leaders. Content analysis on the data was performed.

Results

Data revealed that participation in journal club for nurse leaders gave the leaders a feeling of increased competences to support nursing research culture in their departments. They stated that the action learning approach and the competences of the facilitator were key factors in this outcome.

Conclusions

An action learning‐inspired journal club for nurse leaders can be useful and meaningful to nurse leaders in developing leadership competences.

Implications for nursing management

As an approach in journal club for nurse leaders, action learning can develop nurse leaders' competence to support a research culture, and thus ensure evidence‐based nursing is practised.
