Background: As in many other countries, the Dutch emergency healthcare system is under pressure due to increasing numbers of patients, limited budgets, and constrained (human) resources (TraumaNet AMC 19 May, 2016; Int J Emerg Med 6:41, 2013). eHealth, enlarged by the COVID-19 pandemic, has been advocated to substitute face-to-face care to alleviate the pressure of the burden of care (Ministry of Health Welfare and Sport, 2022; Dutch Society of Hospitals, 2022). In order for eHealth solutions to be adopted in daily practice, is it essential to assess healthcare professionals' attitudes toward its usefulness.

Background: General anaesthesia is provided to more than 300 million surgical patients worldwide, every year. It is administered either through total intravenous anaesthesia, using only intravenous agents, or through inhalational anaesthesia, using volatile anaesthetic agents. The debate on how this affects postoperative patient outcome is ongoing, despite an abundance of published trials.

Article Synopsis
  • Nitrous oxide (NO), commonly used in general anesthesia, is also a problematic greenhouse gas and contributes to ozone depletion, prompting a study on its effects on patient outcomes post-surgery.
  • A systematic review of literature including 71 randomized controlled trials with over 22,000 patients found that NO did not significantly impact postoperative mortality or most morbidity outcomes, though it increased certain complications like atelectasis and nausea.
  • The results suggest that limiting NO use due to its environmental effects does not compromise patient safety, supporting current policy recommendations.

Background: To cope with the rising number of patients with trauma in an already constrained Dutch health care system, Direct Discharge (DD) has been introduced in over 25 hospitals in the Netherlands since 2019. With DD, no routine follow-up appointments are scheduled after the emergency department (ED) visit, and patients are supported through information leaflets, a smartphone app, and a telephone helpline. DD reduces secondary health care use, with comparable patient satisfaction and primary health care use.

When making choices in healthcare, in addition to quality, affordability and accessibility, sustainability (climate and environmental impact) must also be taken into account. Dutch healthcare is responsible for 7% of the entire CO2 footprint, 4% of all waste and 13% of raw material consumption. In addition to the fact that making buildings and processes in healthcare more sustainable is desperately needed, we advocate that we also look at the care provided.

Article Synopsis
  • The study analyzed randomized controlled trials (RCTs) published from 2014 to 2021 in top general medicine journals, focusing on ICU trials compared to non-ICU trials.
  • Out of 2,431 original RCTs, only 132 (5.4%) were ICU-related, with a noticeable increase over the years, yet they displayed significantly lower rates of commercial funding and statistical significance.
  • The findings suggest that while ICU RCTs are on the rise, they often yield less reliable and clinically relevant results, indicating a need for better expectations and designs when conducting these trials.

Background: Reuse of health care data for various purposes, such as the care process, for quality measurement, research, and finance, will become increasingly important in the future; therefore, "Collect Once Use Many Times" (COUMT). Clinical information models (CIMs) can be used for content standardization. Data collection for national quality registries (NQRs) often requires manual data entry or batch processing.

Research Question: What is the risk of hypogonadism in men with obstructive azoospermia, non-obstructive azoospermia (NOA) or Klinefelter syndrome after testicular sperm extraction (TESE)?

Design: This prospective longitudinal cohort study was carried out between 2007 and 2015.

Results: Around 36% of men with Klinefelter syndrome, 4% of men with obstructive azoospermia and 3% of men with NOA needed testosterone replacement therapy (TRT). Klinefelter syndrome was strongly associated with TRT while no association was found between obstructive azoospermia or NOA and TRT.

Study Question: What is the impact of cancer or hematological disorders on germ cells in pediatric male patients?

Summary Answer: Spermatogonial quantity is reduced in testes of prepubertal boys diagnosed with cancer or severe hematological disorder compared to healthy controls and this reduction is disease and age dependent: patients with central nervous system cancer (CNS tumors) and hematological disorders, as well as boys <7 years are the most affected.

What Is Known Already: Fertility preservation in pediatric male patients is considered based on the gonadotoxicity of selected treatments. Although treatment effects on germ cells have been extensively investigated, limited data are available on the effect of the disease on the prepubertal male gonad.

Study Question: Is intracervical insemination (ICI) non-inferior to IUI with cryopreserved donor sperm in the natural cycle in terms of live birth?

Summary Answer: ICI with cryopreserved donor sperm in the natural cycle was inferior to IUI in terms of live birth.

What Is Known Already: Both ICI and IUI in the natural cycle are performed as first-line treatments in women who are eligible for donor sperm treatment. High-quality data on the effectiveness of ICI versus IUI with cryopreserved donor sperm in the natural cycle in terms of live birth is lacking.

Article Synopsis
  • The study aimed to investigate the frequency of outcome switching in follow-up publications of randomized controlled trials (RCTs), which can bias results and exaggerate treatment benefits.
  • Analyzed publications from 2014-2018 in major medical journals, comparing primary outcomes of follow-ups to original RCTs and protocols, finding that 40% had different primary outcomes.
  • The findings revealed that in 55% of cases with switched outcomes, there was no prior specification or explanation, with switching rates rising to 70% if the initial RCT had also switched outcomes.

Study Question: Do parental characteristics and treatment with ART affect perinatal outcomes in singleton pregnancies?

Summary Answer: Both parental and ART treatment characteristics affect perinatal outcomes in singleton pregnancies.

What Is Known Already: Previous studies have shown that singleton pregnancies resulting from ART are at risk of preterm birth. ART children are lighter at birth after correction for duration of gestation and at increased risk of congenital abnormalities compared to naturally conceived children.

Loss-of-function mutations in the X-linked immunoglobulin superfamily, member 1 () gene result in central hypothyroidism, often associated with macroorchidism. Testicular enlargement in these patients might be caused by increases in follicle-stimulating hormone (FSH) levels, as IGSF1 has been proposed to function as an inhibin B receptor or as an inhibitor of activin type I receptor (ALK4) activity in pituitary gonadotrope cells. If true, loss of IGSF1 should lead to reduced inhibin B action or disinhibition of activin signaling, thereby increasing FSH synthesis.

Study Question: Is IVF with frozen-thawed blastocyst transfer (freeze-all strategy) more effective than IVF with fresh and frozen-thawed blastocyst transfer (conventional strategy)?

Summary Answer: The freeze-all strategy was inferior to the conventional strategy in terms of cumulative ongoing pregnancy rate per woman.

What Is Known Already: IVF without transfer of fresh embryos, thus with frozen-thawed embryo transfer only (freeze-all strategy), is increasingly being used in clinical practice because of a presumed benefit. It is still unknown whether this new IVF strategy increases IVF efficacy.

Study Question: Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting?

Summary Answer: Consensus definitions for individual core outcomes, contextual statements, and a standardized reporting table have been developed.

What Is Known Already: Different definitions exist for individual core outcomes for infertility. This variation increases the opportunities for researchers to engage with selective outcome reporting, which undermines secondary research and compromises clinical practice guideline development.

Study Question: Can a core outcome set to standardize outcome selection, collection, and reporting across future infertility research be developed?

Summary Answer: A minimum data set, known as a core outcome set, has been developed for randomized controlled trials (RCT) and systematic reviews evaluating potential treatments for infertility.

What Is Known Already: Complex issues, including a failure to consider the perspectives of people with fertility problems when selecting outcomes, variations in outcome definitions, and the selective reporting of outcomes on the basis of statistical analysis, make the results of infertility research difficult to interpret.

Study Design, Size, Duration: A three-round Delphi survey (372 participants from 41 countries) and consensus development workshop (30 participants from 27 countries).

Study Question: To what extent do characteristics of germline genome editing (GGE) determine whether the general public supports permitting the clinical use of GGE?

Summary Answer: The risk that GGE would cause congenital abnormalities had the largest effect on support for allowing GGE, followed by effectiveness of GGE, while costs, the type of application (disease or enhancement) and the effect on child well-being had moderate effects.

What Is Known Already: Scientific progress on GGE has increased the urgency of resolving whether and when clinical application of GGE may be ethically acceptable. Various expert bodies have suggested that the treatment characteristics will be key in determining whether GGE is acceptable.
