The effects of e-health care on health outcomes and psychological distress in patients undergoing assisted reproductive technology: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Many studies have reported that electronic health (e-health) care helps health professionals manage patients undergoing assisted reproductive technology (ART) and improves their reproductive outcomes and psychological distress. However, little is known about the effectiveness of e-health care on the health outcomes of patients undergoing ART.

OBJECTIVES

This study aimed to evaluate the effectiveness of e-health care on patient-centered health outcomes, such as live birth rate, pregnancy rate, time to pregnancy, etc. as well as psychological distress (i.e., infertility distress and anxiety) among individuals undergoing ART.

DESIGN

A systematic review with random-effects or fixed-effects meta-analysis was conducted to compare e-health interventions with usual care in patients undergoing ART.

METHOD

Electronic database, including Medline, EMBASE, Web of Science, CINHAL, and CENTRAL, were systematically searched from the inception to December 01, 2023. The authors independently reviewed the articles based on inclusion and exclusion criteria, extracted data, and assessed risk of bias used the Cochrane Risk of Bias tool version 2.0. Heterogeneity was evaluated with I2 and Chi-square. We pooled data from each study using fixed-effects meta-analysis if heterogeneity was low. Random-effects meta-analysis was used to pool data with high heterogeneity. Subgroup analysis (i.e., data collection time point) and sensitivity analysis was performed.

RESULT

Data were synthesized from 21 articles covering a total of 6,749 participants (female:6,227; male:522). Pooled analysis showed that e-health care may not increase live birth rate (RR 1.44 95 %CI0.78-2.67, P = 0.25). The clinical pregnancy rate was increased to 1.57 times in the e-health care group compared with the control group (Z = 2.19, P = 0.03) and the e-health care group had an increase in time to pregnancy by 17.40 days than that of the control group (Z = 2.13, P = 0.03). Lower score of Fertility Problem Inventory-social subscale was found in the e-health care group. Subgroup analysis showed that the risk ratio of clinical pregnancy was 3.07 (95 %CI 1.60-5.89) in < 3 months group, 1.21 (95 %CI 0.93-1.59) in ≥3 months group. The fertility-related knowledge level in e-health group was higher than that of the control group (Z = 2.01, P = 0.04).

CONCLUSION

Low certainty evidence suggests that e-health care increases the clinical pregnancy rate after the intervention. Additionally, e-health care benefits in improving perceived infertility-related stress specific to social and the level of infertility-related knowledge. Future studies are needed to establish core outcome measures for e-health intervention targeting infertile individuals.

Efficacy and safety of a smartphone application-based treatment of ketogenic diet in pediatric refractory epilepsy

OBJECTIVE

We aimed to find predictors for smartphone application-based ketogenic diet (KD) treatment effectiveness and safety.

METHODS

The efficacy was evaluated according to the reduction in seizure frequency after the intervention of KD; safety was evaluated based on adverse effects. The ordinal logistic regression analysis was used to explore the influencing factors of efficacy.

RESULTS

The study sample included 116 males and 65 females with a median age of 2.27 years. The baseline frequency of seizure was more than five times/day in 123 children, 50.83% of them received three or more antiepileptic drugs (AEDs). Seventy-two patients' KD initiation mode was outpatient, and 73 completed the 12-month follow-up. A total of 88 (48.62%) patients had reported a reduction in seizure ≥50%. Compared with 12 months, those who had received KD therapy for only 3 (P = 0.009) and 6 months (P = 0.005) were more likely to show negative outcomes. Outpatient initiation had better outcomes (P = 0.029) than inpatient initiation. For the number of AEDs applied, patients on two AEDs were more likely to achieve better outcomes (P = 0.001). Adverse events had been noted among 77 patients; BMI Z-score at KD initiation was associated with adverse effects (P = 0.003).

SIGNIFICANCE

Our study suggested that outpatient initiation and long-term treatment of KD should be encouraged.

PLAIN LANGUAGE SUMMARY

Our research shows that the KD is a helpful treatment for children with refractory epilepsy, reducing seizures by more than 50% in nearly half of the cases, with some experiencing complete seizure freedom. We used a smartphone app to improve communication between patients and their healthcare teams, resulting in a high retention, and app usage was linked to reduced adverse effects. We recommend early consideration of KD treatment for patients failing two AED, encourage outpatient initiation, and advocate for longer-term KD use.

Prolongation of the Menstrual Cycle After Receipt of the Primary Series and Booster Doses of mRNA Coronavirus Disease 2019 (COVID-19) Vaccination

OBJECTIVE

To quantitatively evaluate the effect of a booster vaccination dose against coronavirus disease 2019 (COVID-19) on menstrual cycle in a large-scale retrospective cohort study using a menstrual cycle tracking smartphone application (app).

METHODS

Prospectively or retrospectively recorded data, including the start and finish dates of menstrual cycles, were collected with the app. Detailed data on vaccinations, side effects, and participants' characteristics were retrospectively collected from a questionnaire on the app. For each COVID-19 vaccination shot (first, second, and third), within-individual changes in menstrual cycle length up to the fourth postvaccination cycle were evaluated.

RESULTS

Among the 7,376 and 6,873 participants who had the first and second COVID-19 vaccine doses in different menstrual cycles, respectively, menstrual cycles immediately after the vaccination (first postvaccination cycles) were an average of 0.22 days (95% CI, 0.06-0.39) and 0.37 days (95% CI, 0.20-0.54) longer than the prevaccination cycle. In contrast, among the 1,672 participants who received the first and second doses in the same cycle, the first postvaccination cycle was an average of 4.21 days (95% CI, 3.69-4.72) longer. The second to fourth postvaccination cycles returned to the level of the prevaccination cycle. However, among the 4,768 participants who had the third COVID-19 vaccine dose, the menstrual cycle immediately after the vaccination was an average of 1.20 days (95% CI, 1.00-1.40) longer, with prolongation of cycles of 0.27 days (95% CI, 0.10-0.44) to 0.41 days (95% CI, 0.22-0.59) persisting from the second to the fourth postvaccination cycle.

CONCLUSION

The booster shot against COVID-19 may have a greater and longer-lasting effect on menstrual cycles than the primary-series shots. Although the effect size was small, evidence on the side effects of immunization on menstruation should be accumulated.

Quality controlled YouTube content intervention for enhancing health literacy and health behavioural intention: A randomized controlled study

Background

Individuals increasingly turn to the Internet for health information, with YouTube being a prominent source. However, the quality and reliability of the health information vary widely, potentially affecting health literacy and behavioural intentions.

Methods

To analyse the impact of health information quality on health literacy and behavioural intention, we conducted a randomized controlled trial using a quality-controlled YouTube intervention. Health information quality on YouTube was evaluated using the Global Quality Score and DISCERN. We randomly allocated (1 : 1) to the intervention group to watch the highest quality-evaluated content and to the control group to watch the lowest quality-evaluated content. Health literacy and health behavioural intention were assessed before and after watching YouTube. The trial was set for two different topics: interpreting laboratory test results from health check-up and information about inflammatory bowel disease (IBD).

Results

From 8 April 2022 to 15 April 2022, 505 participants were randomly assigned to watch either high-quality content (intervention group, n = 255) or low-quality content (control group, n = 250). Health literacy significantly improved in the intervention group (28.1 before and 31.8 after; p < 0.01 for health check-up; 28.3 before and 31.3 after; p < 0.01 for IBD). Health behavioural intention significantly improved in the intervention group (3.5 before and 4.1 after; p < 0.01 for health check-up; 3.6 before and 4.0 after; p < 0.01 for IBD). Control groups had no such effect.

Conclusion

High-quality health information can enhance health literacy and behavioural intention in both healthy individuals and those with specific conditions like IBD. It stresses the significance of ensuring reliable health information online and calls for future efforts to curate and provide access to high-quality health content.

Distribution of the follicular and luteal phase lengths and their age-dependent changes in Japanese women: A large population study

Purpose

The current definition of menstrual cycle length in a Japanese woman is different from those of WHO definition, and the original data are outdated. We aimed to calculate the distribution of follicular and luteal phases length in modern Japanese women with various menstrual cycles.

Methods

This study determined the lengths of the follicular and luteal phases of Japanese women using basal body temperature data collected via a smartphone application from 2015 to 2019, and the data were analyzed using the Sensiplan method. Over 9 million temperature readings from more than 80 000 participants were analyzed.

Results

The mean duration of the low-temperature (follicular) phase averaged 17.1 days and was shorter among participants aged 40-49 years. The mean duration of the high-temperature (luteal) phase was 11.8 days. The variance and maximum-minimum difference of the length of the low temperature period were significant in women under 35 years old than women aged more than 35 years.

Conclusions

The shortening of the follicular phase in women aged 40-49 years implied a relationship with the rapid decline of ovarian reserve in these women, and the age 35 years old was turning point of ovulatory function.
