Oh Baby! A Content Analysis of Contraception Pins on Pinterest

BACKGROUND

Social media platforms have become a popular source for health information despite concerns about the quality of content shared. We examined how oral contraceptive pills and intrauterine devices are framed on the platform Pinterest using the Health Belief Model (HBM), as well as how fertility awareness methods are portrayed as an alternative to hormonal contraception.

METHODS

We collected pins in February 2021 using searches for birth control, oral contraceptives, and intrauterine devices. After excluding paid ads and pins not relevant to contraceptive use, we conducted a content analysis of 404 pins using a coding framework grounded in the HBM. We carried out descriptive statistics for all variables in the final sample.

RESULTS

Following coding, we found that 54.7% of pins mentioned oral contraceptive pills, 41.58% mentioned intrauterine devices, and 11.63% mentioned fertility awareness methods. Fertility awareness pins had the highest percentage of benefits conveyed (70.21%), followed by intrauterine devices (44.05%), then oral contraceptive pills (38.91%). Pill pins had the highest percentage of barriers conveyed (52.94%) and fertility awareness had the least (25.53%). Side effects were the most mentioned barrier among pill (37.10%) and intrauterine device pins (23.21%). Very few pins were made by (2.48%) or originated with medical institutions (5.45%).

CONCLUSIONS

Oral contraceptive pills are often negatively framed on Pinterest, whereas intrauterine devices and fertility awareness methods are more positively framed. This suggests a need for clear communication from clinicians regarding all contraceptive options and their relative merits and risks.

Vaccination or NPI? A conjoint analysis of German citizens' preferences in the context of the COVID-19 pandemic

This research uses discrete choice-based conjoint analysis that elicits the preference structure of German citizens when it comes to their timely intention to vaccinate. The focus is on the trade-offs between pharmaceuticals (vaccine) and "non-pharmaceutical interventions" (NPIs) such as lock-downs and social distancing measures, as well as the value of voluntary versus mandatory compliance to the citizens. Our results highlight three critical insights: (a) value of waiting: at 70% effective vaccine, 1/3 of citizens still would prefer to be vaccinated in the next 6 months rather than immediately; (b) costs of NPI constraints: an effective vaccine may come as a solution to compensate for the costs induced by invasive NPI imposed for an extended period; (c) freedom of choice: voluntary compliance is preferred by citizens over imposed measures whether it relates to vaccination choice, lock-down measures, or work location choice during the pandemic. Backing up those findings in monetary value, a quick shot of a 100% effective vaccination is estimated to be worth in the range of 11,400€. Still, the value of the shot quickly falls to no value when effectiveness drops below 50. At the same time, the cost of imposing protective rules lies in the range of 1500-2500€, depending on the rule analyzed. In comparison, the burden of extra complete lock-down and social distancing is about 775€ per citizen per month. As most current vaccines are being proven to have high efficacy, a strategy that selects the most effective vaccine candidates while emphasizing how the vaccine may stop the pain of lasting lock-downs will be appropriate to nudge the population towards vaccination. Control measures that are too restrictive may be welfare-deteriorating, but enough NPI measures must be recommended as long as vaccination adoption is not sufficiently large.

Nisoldipine Inhibits Influenza A Virus Infection by Interfering with Virus Internalization Process

Influenza virus infections and the continuing spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are global public health concerns. As there are limited therapeutic options available in clinical practice, the rapid development of safe, effective and globally available antiviral drugs is crucial. Drug repurposing is a therapeutic strategy used in treatments for newly emerging and re-emerging infectious diseases. It has recently been shown that the voltage-dependent Ca²⁺ channel Cav1.2 is critical for influenza A virus entry, providing a potential target for antiviral strategies. Nisoldipine, a selective Ca²⁺ channel inhibitor, is commonly used in the treatment of hypertension. Here, we assessed the antiviral potential of nisoldipine against the influenza A virus and explored the mechanism of action of this compound. We found that nisoldipine treatment could potently inhibit infection with multiple influenza A virus strains. Mechanistic studies further revealed that nisoldipine impaired the internalization of the influenza virus into host cells. Overall, our findings demonstrate that nisoldipine exerts antiviral effects against influenza A virus infection and could serve as a lead compound in the design and development of new antivirals.

State Health Department Communication about Long COVID in the United States on Facebook: Risks, Prevention, and Support

Greater public awareness of long COVID severity and susceptibility is needed to support those with long COVID and encourage preventive behaviors. It is not yet known to what extent health departments have informed the public about long COVID risks or offered guidance and support for those with long COVID. The objective of this research was to determine how and to what extent US state health departments have communicated with the public about long COVID via Facebook. Facebook posts with COVID-19 and long COVID terms made by 50 US state health departments plus Washington, DC, from 1 January 2020 to 31 January 2022, were collected using CrowdTangle. The first long COVID post appeared on 15 July 2020. From 15 July 2020 to 31 January 2022, state health departments made 49,310 COVID-19 posts and 137 long COVID posts. Using quantitative content analysis methods, long COVID posts were coded for health belief model constructs. Among long COVID posts, 75.18% included language about susceptibility, 64.96% severity, and 64.23% benefits of prevention. Cues to preventive action appeared in 54.01% of posts. 19.71% of posts provided guidance for those with long COVID. While health departments posted extensively about COVID-19, posts about long COVID were rare. This represents a missed opportunity to bolster arguments for preventive behaviors and support those experiencing long COVID.

Influenza Vaccination for the Prevention of Cardiovascular Disease in the Americas: Consensus document of the Inter-American Society of Cardiology and the Word Heart Federation

Background

Cardiovascular mortality is decreasing but remains the leading cause of death world-wide. Respiratory infections such as influenza significantly contribute to morbidity and mortality in patients with cardiovascular disease. Despite of proven benefits, influenza vaccination is not fully implemented, especially in Latin America.

Objective

The aim was to develop a regional consensus with recommendations regarding influenza vaccination and cardiovascular disease.

Methods

A multidisciplinary team composed by experts in the management and prevention of cardiovascular disease from the Americas, convened by the Inter-American Society of Cardiology (IASC) and the World Heart Federation (WHF), participated in the process and the formulation of statements. The modified RAND/UCLA methodology was used. This document was supported by a grant from the WHF.

Results

An extensive literature search was divided into seven questions, and a total of 23 conclusions and 29 recommendations were achieved. There was no disagreement among experts in the conclusions or recommendations.

Conclusions

There is a strong correlation between influenza and cardiovascular events. Influenza vaccination is not only safe and a proven strategy to reduce cardiovascular events, but it is also cost saving. We found several barriers for its global implementation and potential strategies to overcome them.
