Introduction: The digital nerve block is an effective method of anesthesia before minor surgical interventions on the fingers. However, patients may experience a lot of pain and anxiety during this procedure. The efficacy of topical vapocoolant spray during minor procedures has been demonstrated in previous studies. we aimed to evaluate the effectiveness of topical vapocoolant spray in reducing pain during digital nerve block.
Methods: This prospective, randomized clinical study was conducted to evaluate the effectiveness of vapocoolant spray application in reducing pain during digital block. The patients were categorized into 2 groups as spray-treated and control group. A routine digital block process was applied to the control group. Spray application was performed in two groups of 50 each, in a manner of bilateral and unilateral to the finger. Demographic data of the patients, such as gender, age, dominant hand, injury patterns, injection site and injury sites, were recorded. After the application, the patients' visual analog scale (VAS) was evaluated.
Results: Of the participants, 100 were randomly assigned to the vapocoolant spray-treated group, and 50 were included in the control group. The VAS pain score during penetration in both spray groups was significantly lower than the control group (p < 0.001). Pain change during penetration was found to be significantly lower in the bilateral spray-treated group compared to the control group (p < 0.001). Pain change during infiltration was significantly lower in both spray groups compared to the control group (p < 0.001).
Conclusions: Spray application prior to digital nerve blocking can be used to reduce needle penetration pain associated with this procedure and pain associated with local anesthetic infiltration.

Background: People who inject drugs (PWID) are especially vulnerable to harms from opioid use disorder (OUD). Medications for OUD (MOUD) effectively reduce overdose and infectious disease transmission risks.
Objective: We investigate whether state Medicaid coverage for methadone and buprenorphine is related to past-year MOUD use among PWID using cross-sectional, multilevel analyses with individual-level data on PWID from the Centers for Disease Control and Prevention's 2018 National HIV Behavioral Surveillance.

Background: Bicycle messengers in the online food delivery sector typically work on an on-demand basis, have digitally mediated relationships with their employer, and have very limited labor rights. In this study, we explore how bicycle messengers themselves experience their workday and how platform work influences their identity and wellbeing.
Method: We conducted qualitative interviews with ten bicycle messengers working for Foodora and Wolt in Bergen and Oslo, Norway.

Background: Autistic people commonly have physical and mental health conditions. They also frequently experience barriers to accessing healthcare, contributing to problems identifying and treating health conditions. These factors may lead to increased and earlier morbidity and lower average life expectancy for autistic people.

Background: Perianal fistula is one of the complications of deepened anal fissure. The present case-control study aimed to assess the risk factors of fissure-associated fistulas due to the limited available evidence.
Methods: Patients with fissure-associated fistulas were considered as case, and patients with anal fissure who were undergoing medical treatment without any previous anorectal surgeries were considered as control group.
