Abstract

Background
Breast milk is a natural and unique nutrient for optimum growth and development of the newborn. The aim of this study was to investigate the presence of unpredictable drug residues in mothers’ milk and the relationship between drug residues and maternal-infant characteristics.

Methods
In a descriptive study, breastfed infants under 3 months of age and their mothers who applied for child health monitoring were enrolled for the study. Information forms were completed for maternal-infant characteristics, breastfeeding problems, crying and sleep characteristics of infants. Maternal and infant anthropometric measurements and maternal milk sample were taken. Edinburgh Postpartum Depression Scale was applied to mothers. RANDOX Infiniplex kit for milk was used for residual analysis.

Results
Overall, 90 volunteer mothers and their breastfed infants were taken into the study and the mean age of the mothers and their infants was 31.5 ± 4.2 years and 57.8 ± 18.1 days, respectively. Anti-inflammatory drug residues in breast milk were detected in 30.0% of mothers and all had tolfenamic acid. Overall, 94.4% had quinolone, 93.3% beta-lactam, 31.1% aminoglycoside and 13.3% polymycin residues. Drugs used during pregnancy or lactation period were not affected by the presence of residues. Edinburgh postpartum depression scores of mothers and crying and sleeping problems of infants were similar in cases with and without drug residues in breast milk. When controlling confounding factors, maternal body mass index alterations were detected to be significantly lower in mothers with anti-inflammatory drug residues in breast milk than in their counterparts (p = 0.017).

Conclusions
Our study suggests that there are unpredictable drug residues in the milk of many mothers. Anti-inflammatory drug exposure might affect maternal weight change during the postpartum period. Further studies are required to evaluate the impact of drug residues on maternal and infant health.

Abstract

Background
Maternal perceptions about caesarean section contribute to delayed presentation of women for emergency obstetric care. This increases the risks of perinatal and neonatal mortality and slows down the reductions needed to achieve the sustainable development goal (SDG) target of reducing neonatal mortality and ending new-born deaths. The aim of the study is to determine maternal perceptions about caesarean section deliveries and their role in reducing neonatal mortality at a regional and a district hospital in the Upper West Region of Ghana.

Methods
This descriptive study was carried out at two hospitals in the Upper West Region, the most rural region in Ghana, between 15th January and 29th June, 2018. Maternal perceptions were examined among antenatal care attendants at the Upper West Regional Hospital (UWRH) and St Joseph’s Hospital Jirapa (SJH), a district hospital, using questionnaires administered by trained nurses.

Results
Altogether, 416 completed questionnaires were obtained, comprising 206 from expectant women attending the UWRH and 210 from SJH. Although the majority of women in this study preferred spontaneous vaginal delivery (87.4%, n = 348) to caesarean section, most of the respondents (n = 281, 73%) indicated their willingness to have a caesarean section if necessary. The main reason for not wanting a CS was the long recovery time (51.8%, n = 148). Almost half of women interviewed, representing 45.1% (180) did not know or feel that CS can promote child survival and about a fifth, 21.6% (85) believed that CS can have adverse effects on child survival. Factors associated with poor perception of CS included, no formal education, age less than 19 years and no employment.

Conclusion
Majority of women in this study had a positive attitude towards the uptake of CS if it becomes necessary. Lack of formal education, age less than 19 years and unemployment are associated with poor maternal perception of CS. Education to improve the perception of CS as a promoter of child survival is necessary and to discourage perceptions that it causes adverse perinatal or neonatal outcome particularly in at risk populations.

Abstract

Background
DNA ligase IV deficiency is a rare autosomal recessive disorder caused by hypomorphic mutations in the DNA ligase IV (LIG4) gene. DNA ligase IV is an essential protein for the development of a healthy immune system as well as for the protection of genomic integrity. Apart from typical stigmata, patients with DNA ligase IV deficiency are characterized by progressive bone marrow failure and a predisposition to malignancy. To our knowledge this reported case is the first description of two brothers with ligase IV deficiency who are treated with different hematopoietic stem cell transplantation (HSCT) regimens resulting in vastly divergent outcomes.

Case presentation
The cases of two brothers suffering from severe recurrent infections and growth retardation are described. The laboratory findings showed pancytopenia with significant lymphopenia. The two boys were diagnosed with DNA ligase IV deficiency, associated with severe combined immunodeficiency (SCID). Both patients received HSCT from two different matched unrelated donors (MUD) at the age of 33 and 18 months. The older brother succumbed post-transplant due to fatal side-effects 143 days after allogeneic HSCT. The younger brother – conditioned with a different regimen – received a T cell depleted graft 4 months later. No severe side-effects occurred, neither post-transplant nor in the following years. Ten years after HSCT the patient is well off, living a normal life and attending a regular high school. His immune system is fully reconstituted, resulting in a maximum of T cell receptor (TCR) diversity, which is a prerequisite for immune competence. However, he still suffers from microcephaly, dwarfism and dystrophy.

Conclusions
This case report gives an example of a successful HSCT as a treatment option in a genetic disorder such as ligase IV deficiency, using a rather mild conditioning regimen. Further studies are required to determine the viability and efficacy of this treatment option.

Abstract

Background
Flea bite is considered to be the main cause of allergic dermatitis in cats. There is a need for treatments able to control clinical signs of allergic dermatitis associated with flea bite in cats.
This was an open pre-treatment versus post-treatment clinical field study. All cats included in the study presented pruritus, skin lesions or other evidence compatible with flea infestation. Skin lesions were assessed (using SCORFAD) at days 0, 28, 56 and 84 whereas pruritus severity was assessed (using PVAS) at days 0, 15, 28, 56 and 84. On day 0, The fluralaner (280 mg/ml) product (Bravecto® spot-on for cats) was supplied in pipettes containing 0.4, 0.89 and 1.79 ml for cats of 1.2–2.8 kg, > 2.8–6.25 kg and > 6.25–12.5 kg body weight, respectively. The other animals living in the same household also received fluralaner. Based on cytological examination at day 0, oral amoxicillin and clavulanic acid was prescribed for 21 days if indicated. For cats presenting intense pruritus and discomfort at day 0, oral prednisolone at 0.5 mg/kg was prescribed for 3 days.

Results
During the study all cats, except for one (cat number 10), improved significantly. Post-treatment median SCORFAD scores at all evaluations were significantly different from the pre-treatment score on day 0 (P values < 0.002 for all three post treatment examination days) with a score reduction of 49% on day 28, 79% on day 56 and 87% on day 84. The PVAS score decreased significantly over the study period for all cats but one (cat number 10). Post-treatment median PVAS scores at all evaluations were significantly different from the pre-treatment PVAS score on day 0 (P value < 0.002 for all four post-treatment days) with a reduction of 46% on day 15, 67% on day 28, 82% on day 56 and 92% on day 84. No adverse reaction or other health issue was reported during the study.

Conclusions
A single topical treatment with fluralaner results in a significant reduction of flea bite allergic dermatitis clinical signs in cats over the subsequent 12 weeks without any additional environmental treatment.

AbstractBackgroundThe pathogenesis and cardiovascular impact of type 2 diabetes (T2D) may be different in South Asians compared with other ethnic groups. The phenotypic characterization of diabetic cardiomyopathy remains debated and little is known regarding differences in T2D-related cardiovascular remodeling across ethnicities. We aimed to characterize the differences in left ventricular (LV) diastolic and systolic function, LV structure, myocardial tissue characteristics and aortic stiffness between T2D patients and controls and to assess the differences in T2D-related cardiovascular remodeling between South Asians and Europeans.MethodsT2D patients and controls of South Asian and European descent underwent 3 Tesla cardiovascular magnetic resonance imaging (CMR) and cardiac proton-magnetic resonance spectroscopy (1H-MRS). Differences in cardiovascular parameters between T2D patients and controls were examined using ANCOVA and were reported as mean (95% CI). Ethnic group comparisons in the association of T2D with cardiovascular remodeling were made by adding the interaction term between ethnicity and diabetes status to the model.ResultsA total of 131 individuals were included (54 South Asians [50.1 ± 8.7 years, 33% men, 33 patients vs. 21 controls) and 77 Europeans (58.8 ± 7.0 years, 56% men, 48 patients vs. 29 controls)]. The ratio of the transmitral early and late peak filling rate (E/A) was lower in T2D patients compared with controls, in South Asians [− 0.20 (− 0.36; − 0.03),P = 0.021] and Europeans [− 0.20 (− 0.36; − 0.04),P = 0.017], whereas global longitudinal strain and aortic pulse wave velocity were similar. South Asian T2D patients had a higher LV mass [+ 22 g (15; 30),P < 0.001] (Pfor interaction by ethnicity = 0.005) with a lower extracellular volume fraction [− 1.9% (− 3.4; − 0.4),P = 0.013] (Pfor interaction = 0.114), whilst European T2D patients had a higher myocardial triglyceride content [+ 0.59% (0.35; 0.84),P = 0.001] (Pfor interaction = 0.002) than their control group.ConclusionsDiabetic cardiomyopathy was characterized by impaired LV diastolic function in South Asians and Europeans. Increased LV mass was solely observed among South Asian T2D patients, whereas differences in myocardial triglyceride content between T2D patients and controls were only present in the European cohort. The diabetic cardiomyopathy phenotype may differ between subsets of T2D patients, for example across ethnicities, and tailored strategies for T2D management may be required.

Abstract

Background
Pancreatic cancer is a malignancy with a very poor prognosis. The emergence of liquid biopsy is expected to achieve accurate early diagnosis through detection of tumor-derived secreted proteins in the blood. Early diagnosis and treatment of pancreatic cancer could help to improve prognosis.

Methods
The pretreatment approach of samples can have a major effect on downstream analysis. In this study, we used a pair of homologous pancreatic cancer cell supernatants with different capacities for invasion and metastasis to examine secreted proteins in the conditioned media without the removal of fetal bovine serum, namely through size exclusion chromatography combined with high-abundance protein affinity chromatography to enrich low-concentration protein, followed by mass spectrometry using triple dimethyl labeling. Identification of proteins was performed using an online public database and western blot.

Results
Mass spectrometry data revealed 77 proteins with quantitative properties, of which 12 proteins had over a 1.5-fold difference (in the supernatant of the highly invasive pancreatic cancer cell line PC-1.0, the expression of 8 proteins were increased and the expression of 4 proteins were decreased). Bioinformatics analysis results showed that CCT8, CTSL, SAA1, IGF2 are secreted via the exosome pathway. According to the literature, with the exception of CCT8, the other three proteins can be detected in blood samples of pancreatic cancer patients, and they can be used as prognostic markers. Western blot results were used to validate consistency with MS results.

Conclusion
This study found that CCT8 can be used as a liquid biopsy marker to assess the prognosis of pancreatic cancer patients.

Abstract

Background
Conventional risk prediction techniques may not be the most suitable approach for personalized prediction for individual patients. Therefore, individualized predictive modeling based on similar patients has emerged. This study aimed to propose a comprehensive measurement of patient similarity using real-world electronic medical records data, and evaluate the effectiveness of the individualized prediction of a patient’s diabetes status based on the patient similarity.

Results
When using no more than 30% of the whole training sample, the personalized predictive models outperformed corresponding traditional models built on randomly selected training samples of the same size as the personalized models (P < 0.001 for all). With only the top 1000 (10%), 700 (7%) and 1400 (14%) similar samples, personalized random forest, k-nearest neighbor and logistic regression models reached the globally optimal performance with the area under the receiver-operating characteristic (ROC) curve of 0.90, 0.82 and 0.89, respectively.

Conclusions
The proposed patient similarity measurement was effective when developing personalized predictive models. The successful application of patient similarity in predicting a patient’s diabetes status provided useful references for diagnostic decision-making support by investigating the evidence on similar patients.
Liraglutide exhibits anti-inflammatory activity through the activation of the PKA/CREB pathway
Authors: Wang Li , Feng Linjie , Zhang Jingyu 
Published: October 2019

Abstract
Qihong Que and colleagues found that liraglutide exhibited anti-inflammatory activity through the activation of the PKA/CREB pathway in an OA rat model. We believe there was a flaw in this research. In their first experiment, the sacrifice time of the 10 rats in the control group has not been stated. And when the rats in the OA-1, OA-5, OA-10, OA-20 and OA-28 groups were sacrificed, they were in different weeks of age. If the rats in the control group were compared to the rats in the OA-1, OA-5, OA-10, OA-20 and OA-28 groups respectively, the results may be biased due to differences in the week age of the rats. We believe that addressing this issue could further increase the value of their study.

Abstract

Background
Nonuse of contraceptive methods by women in need of contraception may impact their sexual and reproductive health. The aim of this study was to describe the reasons for nonuse of contraception among women with demand for contraception not satisfied in low and middle-income countries (considering both overall countries and various subgroups of women).

Methods
We used the latest Demographic and Health Survey data from 47 countries. A descriptive analysis of the reasons for nonuse of contraceptive methods was performed among sexually active women with demand for contraception not satisfied. The prevalence of each reported reason was also evaluated according to marital status, woman’s age and schooling, area of residence, wealth index, and parity. Wealth-related absolute inequality for each reason was also evaluated using the Slope Index of Inequality. A pro-rich inequality pattern means that the reason is more prevalent among the richest women while a pro-poor means the reason is more common among the poorest ones.

Results
On average, 40.9% of women in need of contraception were not using any contraceptive methods to avoid pregnancy. Overall, the most prevalent reasons for nonuse of contraceptives were “health concerns” and “infrequent sex,” but the prevalence of each reason varied substantially across countries. Nonuse due to “opposition from others” was higher among married than unmarried women; in turn, the prevalence of nonuse due to “lack of access” or “lack of knowledge” was about two times higher in rural areas than in urban areas. Women with less schooling more often reported nonuse due to “lack of access.” Pro-rich inequality was detected for reasons “health concerns,” “infrequent sex,” and “method-related”, while the reasons “other opposed,” “fatalistic,” “lack of access,” and “lack of knowledge” were linked to patterns of pro-poor inequality.

Conclusions
Family planning promotion policies must take into account the different reasons for the nonuse of contraceptive methods identified in each country as well as the contextual differences regarding women of reproductive age (such as social norms and barriers that prevent women from accessing and using contraceptives).
Hepatic PKA inhibition accelerates the lipid accumulation in liver

Published: October 2019

AbstractBackground/aimsLiver lipid accumulation induced by high-fat diet (HFD) is an early onset process of non-alcoholic fatty liver diseases (NAFLD). Protein kinase A (PKA) is known to be involved in hepatic lipid metabolism. However, the role of PKA in NAFLD has not been well tested in vivo due to the lack of optimal PKA deficient mouse model.MethodsA novel PKA-specific inhibitor gene was conditionally overexpressed in mouse (PKAi mouse) liver using LoxP/Cre system. PKA activity in the liver extract was measured with a commercial assay kit. The PKAi and control mice of 8-week age, were subjected to HFD or chow diet (CD) for 2 months. Body weight, liver index, and triglyceride in the liver were measured. RNA sequencing was performed for the liver tissues and analyzed with Gene Ontology (GO) and pathway enrichment.ResultsPKAi-GFP protein was overexpressed in the liver and the PKA activation was significantly inhibited in the liver of PKAi mouse. When fed with CD, RNA sequencing revealed 56 up-regulated and 51 down-regulated genes in PKAi mice compared with control mice, which were mainly involved in lipid metabolism though no significant differences in the body weight, liver index, triglyceride accumulation were observed between PKAi and control mice. However, when fed with HFD for 2 months, the liver was enlarged more, and the accumulation of triglyceride in the liver was more severe in PKAi mice. When comparing the transcriptomes of CD-fed and HFD-fed control mice, GO enrichment showed that the genes down-regulated by HFD were mainly enriched in immune-related GO terms, and up-regulated genes were enriched in metabolism. When comparing the transcriptomes of CD-fed and HFD-fed PKAi mice, GO analysis showed that the down-regulated genes were enriched in metabolism, while the up-regulated genes were clustered in ER stress-related pathways. When comparing HFD-fed PKAi and HFD-fed control mice, the genes with lower expression level in PKAi mice were enriched in the lipoprotein synthesis, which might explain that more TG is accumulated in PKAi liver after HFD feeding.ConclusionsReduced PKA activity could be a factor promoting the TG accumulation in the liver and the development of NAFLD.
