The Vagueness of Integrating the Empirical and the Normative: Researchers' Views on Doing Empirical Bioethics

The integration of normative analysis with empirical data often remains unclear despite the availability of many empirical bioethics methodologies. This paper sought bioethics scholars' experiences and reflections of doing empirical bioethics research to feed these practical insights into the debate on methods. We interviewed twenty-six participants who revealed their process of integrating the normative and the empirical. From the analysis of the data, we first used the themes to identify the methodological content. That is, we show participants' use of familiar methods explained as "back-and-forth" methods (reflective equilibrium), followed by dialogical methods where collaboration was seen as a better way of doing integration. Thereafter, we highlight methods that were deemed as inherent integration approaches, where the normative and the empirical were intertwined from the start of the research project. Second, we used the themes to express not only how we interpreted what was said but also how things were said. In this, we describe an air of uncertainty and overall vagueness that surrounded the above methods. We conclude that the indeterminacy of integration methods is a double-edged sword. It allows for flexibility but also risks obscuring a lack of understanding of the theoretical-methodological underpinnings of empirical bioethics research methods.

High quality social environment buffers infants' cognitive development from poor maternal mental health: Evidence from a study in Bhutan

Poor maternal mental health negatively impacts cognitive development from infancy to childhood, affecting both behavior and brain architecture. In a non-western context (Thimphu, Bhutan), we demonstrate that culturally-moderated factors such as family, community social support, and enrichment may buffer and scaffold the development of infant cognition when maternal mental health is poor. We used eye-tracking to measure early building blocks of cognition: attention regulation and social perception, in 9-month-old Bhutanese infants (N = 121). The cognitive development of Bhutanese infants in richer social environments was buffered from poor maternal mental health, while for infants in environments with lower rates of protective social environment factors, worse maternal mental health significantly predicted greater costs for infant attention, a fundamental building block cognition. International policies and interventions geared to improve maternal mental health and child health outcomes should incorporate each regions' unique family, cultural, and community support structures.

Development of DO*A and DO*B Allele Detections to Predict Transfusion-Induced Alloimmunization Risks in Thai Populations

BACKGROUND

Two antithetical antigens, Doa and Dob of the Dombrock (DO) blood group system are implicated in acute to delayed hemolytic transfusion reactions among patients with anti-Doa or anti-Dob. Given the unavailability of specific antiserum, a polymerase chain reaction with sequence-specific primer (PCR-SSP) was developed to identify DO*A and DO*B alleles. This study aimed to determine DO*A and DO*B allele frequencies and to predict transfusion-induced alloimmunization risks in three Thai blood donor populations.

METHODS

DNA samples obtained from 1,300, 300, and 400 blood donors from central, northern, and southern Thailand, respectively, were genotyped for the DO*A and DO*B allele detections using developed PCR-SSP. The results were confirmed by DNA sequencing.

RESULTS

The validated genotyping results by PCR-SSP were in concordance with DNA sequencing. The DO*B/ DO*B was the most common genotype (77.0, 76.0, and 71.0%), followed by DO*A/DO*B (21.0, 22.7, and 25.2%) and DO*A/DO*A (2.0, 1.3, and 3.8%) among central, northern and southern Thais, respectively. The alleles found among central Thais showed significant differences from those found among southern Thais but not from those of northern Thais. The risk of anti-Doa production was higher than anti-Dob production among Thais. Concerning regional groups, the risk of Doa alloimmunization among southern Thais (0.2059) was higher than those among central (0.1771) and northern Thais (0.1824).

CONCLUSIONS

This was the first study to distinguish DO*A and DO*B genotypes in Thai populations using in-house PCR-SSP. This would be useful to predict alloimmunization risks that might result from transfusion-induced reactions of undetermined red cell antigens among blood donors and in reagent red cells.

The successful implementation of the Enhanced Recovery After Surgery (ERAS) program among caesarean deliveries in Bhutan to reduce the postoperative length of hospital stay

BACKGROUND

Enhanced Recovery After Surgery (ERAS) is a multidisciplinary perioperative care program to optimize and enhance postoperative recovery. It has a beneficial role in decreasing the length of hospital stay and improving the quality of care. This study aims to observe the successful implementation of ERAS in reducing the length of hospital stay (LOS) among caesarean deliveries.

METHODS

A pre-and post-implementation study of ERAS protocol was conducted, among cohort of women who underwent caesarean deliveries from January to December 2020 in the Department of Obstetrics and Gynaecology, Mongar Regional Referral hospital. Data collected retrospectively and analyzed in SPSS (IBM SPSS trial version); and comparison of length of hospital stay between the two groups were tested by t-test.

RESULTS

One hundred seventy-one patients were included in the study: 87 in the pre-ERAS and 84 in the post-ERAS cohort. Post implementation, LOS decreased by an average of 21.0 (CI 16.11-24.64; p-value < 0.001) hours in the postoperative period. A greater proportion of patients were discharged on day-2 (2.3% in pre-ERAS and 81% in ERAS; p-value < 0.001).

CONCLUSION

Implementation of ERAS protocol can significantly decrease the postoperative length of hospital stay without increasing the complications and readmission rates.

Lithium-induced Symptomatic Hypercalcemia and Hyperparathyroidism in a Patient with Bipolar Affective Disorder: A Case Report and Review of Literature

Lithium induced primary hyperparathyroidism is an uncommon endocrine side effect of long term lithium therapy. We studied the case of a 67-year-old female patient on long term lithium therapy for bipolar affective disorder, who developed resistant hypercalcaemia and parathyroid adenoma which required parathyroidectomy. Furthermore, the effect of chronic lithium therapy on parathyroid glands and serum calcium levels, its pathogenesis, and management were reviewed. Periodic monitoring of serum calcium levels in patients on long term lithium therapy should be practiced. Surgical removal of the affected parathyroid gland is an effective treatment modality in selected patients with resistant hypercalcaemia and parathyroid adenoma and/or hyperplasia. However, regular post-operative follow up is needed for early identification of recurrence in such patients.

Experts' perspectives on SwissDRG: Second class care for vulnerable patient groups?

On the 1st of January 2012, Switzerland introduced the diagnosis-related group hospital tariff structure (SwissDRG). It was recognised that healthcare provided to the most vulnerable patient groups would be a challenge for the new SwissDRG. Coincident with the implementation of SwissDRG, we explored hospital experts' perceptions of which patient groups are vulnerable under the SwissDRG system, what has changed for this group, as well as solutions to ensure adequate access to health care for them. We interviewed 43 experts from 40 Swiss hospitals. Participating experts named several vulnerable patient groups who share some common characteristics. These hospital experts were concerned about the patient groups that are not financially profitable and questioned the practicability of the current regulation. At the same time, they highlighted the complexity associated with caring for this group under the new SwissDRG and reported measures at the macro, meso, and micro levels to protect vulnerable patient groups from negative effects. To curb negative outcomes for vulnerable patient groups after the introduction of the SwissDRG, the Swiss legislation has introduced various instruments including the acute and transitional care (ATC) measures. We conclude that ATC measures do not produce the expected effect the legislators had hoped for. More health data is needed to identify situations where vulnerable patient groups are more susceptible to inadequate health care access in Switzerland.
