Chatpiwat Ramjuan, Chayasak Pitsawong, Thanasawat Chaiyakul — Tue, 17 Dec 2024 00:00:00 +0700

Diving activities among female divers are becoming increasingly popular. With the current trend of people being more health-conscious and seeking medical advice regarding diving-related risks, there has been a continuous increase in inquiries for medical recommendations. Upon examining anatomical factors, physiological changes, and individual factors that might affect the performance and risks associated with diving for female divers, it has been found that there is no significant difference in the risk of decompression sickness between female and male divers. However, it is noted that immersion pulmonary edema may be more prevalent in females than in males. Diving during menstruation or while using contraceptives or hormones is generally safe. Female divers who are planning to become pregnant or are currently pregnant should avoid diving. Postpartum women should refrain from diving until surgical wounds are fully healed and there is no risk of infection. Breastfeeding women can safely engage in diving activities since nitrogen does not dissolve in breast milk. Women who are post-menopausal can dive if they do not have any pre-existing health conditions that contraindicate diving or severe osteoporosis of the spine. Additionally, it has been observed that women with breast implants do not have an increased risk of decompression sickness. Therefore, if female divers are well-informed about the potential risks and impacts of diving, they can mitigate dangers and enhance their diving performance. This knowledge and understanding will help female divers to dive more safely and effectively.

Hyperbaric Oxygen Therapy for Athletes: from Basic Principle to Clinical Application

Naruebade Rungrattanawilai — Tue, 17 Dec 2024 00:00:00 +0700

Hyperbaric oxygen therapy (HBO₂T) is indicated for the treatment of diving injuries and other medical problems. HBO₂T’s principal mechanism to treat such conditions is the benefit of increased systemic oxygenation under pressure. Theoretically, this mechanism could have positive effect to athletes in promoting recovery after injuries and enhancing exercise performance. Although recent studies were unable to clinically demonstrate this advantages, many professional athletes and sports authorities applied HBO₂T in their practice. This review of published literature both basic sciences and clinical studies aimed to reveal the concept of HBO₂T used in athletes for proper and most beneficial application. Moreover, further study of HBO₂T in professional athletes during competitive events is required to prove the therapeutic effect in this specific population. Even minimal effect from this modality may be enough to act as a game changer in the final competition.

Psychology of Submariners

Wichian Sripootorn — Tue, 17 Dec 2024 00:00:00 +0700

Mental health problems in submariners are a critical concern within the field of submarine medicine due to the high-risk nature of submarine operations. The unique conditions in which submarines operate increase their susceptibility to developing mental health problems. Compounding this issue is the limited access to medical services, particularly psychiatric treatment, while submerged. The presence of mental health problems or disorders during submarine missions inevitably compromises the safety of both submariners and submarine assets. Therefore, conducting thorough psychological evaluations is of paramount importance in submarine medicine. These evaluations aid in the selection of individuals with specific characteristics suitable for underwater operations, thereby preventing or reducing the risk of mental health problems that may arise. A comprehensive assessment of the factors that may impact submarine mental health is essential in all dimensions. Such assessments provide valuable information for formulating policies on psychological assessments, procuring or developing psychological tests for submariners, and preparing for the mental health needs of submarines. Additionally, these assessments offer important concepts that can be utilized to design programs aimed at enhancing mental performance in a tangible way. These programs promote mental resilience within submarines and equip personnel with the skills necessary to effectively manage stress in high-pressure underwater situations. Ultimately, these efforts contribute to the successful execution of submarine missions and the achievement of the Royal Thai Navy goals.

The Effect of a Digital Note-taking Using Cornell Method on English Listening Comprehension of Nursing Students at the Royal Thai Navy College of Nursing

Kittima Sadhuwong — Tue, 03 Dec 2024 00:00:00 +0700

The recent Royal Thai Navy College of Nursing (RTNCN) English training program was unsuccessful in improving the students’ listening comprehension to meet Thailand Higher Education Policy requirements. The Cornell digital note-taking method was found to be compatible with the cognitive process of listening comprehension for English as a Second Language (ESL) instruction. The research objectives were to investigate the effectiveness of the training program applying the Cornell digital note-taking method to the listening comprehension of RTNCN nursing students.
The quasi-experiment and pretest-posttest control group design was conducted with 42 first-year nursing students of academic year B.E. 2564. Purposive sampling based on the students’ pre-determined criteria and matching of students’ English performances was conducted to allocate students for the experimental and control groups with 21 students each. The experimental group participated in training program by taking the digital note with the Cornell note format while listening. The training phases consisted of preparation, listening, and evaluation. The program was developed by the researcher and verified by a panel of expert. In contrast, the control group completed the notes on paper in an unstructured format. The 1-hour training sessions were conducted for both groups each week over a 12-week period. The TOEIC Model Test was used to assess students’ pretest listening comprehension, and the Official TOEIC Listening Test was used for posttest.
The results found that the listening comprehension score of the experimental group was significantly higher in the posttest than in pretest (Mean = 222.62 ± 35.20 vs. Mean = 181.19 ± 39.99, t(20) = -9.09, p = .000) and the posttest score of the control group respectively (Mean = 222.62 ± 35.20 vs. Mean = 186.43 ± 47.96, t(40) = 2.79, p = .008).
In conclusion, digital note-taking using the Cornell note-taking format can improve the listening comprehension scores, with a focus on preparing students for listening comprehension. This includes taking notes of short texts or sentences, writing down keywords and questions, summarizing, reflecting, reciting, and reviewing.

          This research and development aimed to study the situation, develop a model, and examine the effectiveness of anesthesia care management model among older adults undergoing total hip arthroplasty by applying recovery enhancement program after surgery in Krabi hospital. The implementation process had 3 stages. Stage 1 was study the situation by analyzing documents and using qualitative method. The informants were 15 nurse anesthetists. Data were analyzed using content analysis. Stage 2 was development of a model by using research results from stage 1 before drafting a model which was validated by a panel of 3 experts. Stage 3 was study the effectiveness of developed model by using one group pretest and posttest quasi-experimental research. The sample were 15 nurse anesthetists and 50 patients. Data were analyzed using descriptive statistics, one sample t-test, Wilcoxon signed-rank test and repeated measure ANOVA. The research results were as follows:
          1. For the situation, it was found that patients undergoing total hip arthroplasty had physical deterioration and co-morbidities which resulted in late recovery after surgery, caused complications and nurse anesthetists lacked training of rapid recovery.
          2. The model of anesthesia care management among older adults undergoing total hip arthroplasty consisted of 3 phases including pre-anesthesia, peri-anesthesia and post- anesthesia. The model emphasized patient preparation by a multidisciplinary team from the preoperative phase to ensure safety, prevent complications, and promote faster recovery, as well as information transfer and post-discharge follow-up.
          3. After using the model, nurse anesthetists at Krabi hospital had significantly higher knowledge and satisfaction of using the model (p = .001). Whereas older adults undergoing total hip arthroplasty with anesthesia had significantly lower mean pain scores. The average pain scores tended to decrease from the first 24 hours after surgery, and all elderly patients had pain scores not exceeding 3 at 72 hours and before discharge, which was statistically significant (F = 27.26, p < .001). The patients could perform the same activities of daily living after 1 week of discharge (88%) and had significantly higher satisfaction of using the model more than 80% of criteria (p = .001).

Supapun Kanjanabunyong, Chutima Chantamit-O-Pas, Panicha Ponpinij — Fri, 06 Dec 2024 00:00:00 +0700

This predictive research aimed to assess the adherence to rehabilitation and its influencing factors in stroke patients, including perceived self-efficacy, modified Rankin scale (mRS), social support, fear of falling, and anxiety in COVID-19. The sample consisted of patients with ischemic or hemorrhagic stroke within the first three months after diagnosis, who came for follow-up at four selected hospitals. A total of 109 participants were selected through simple random sampling. Research instruments included demographic data, perceived self-efficacy, mRS, social support, fear of falling, anxiety in COVID-19, and adherence to rehabilitation. Data were analyzed using descriptive statistics and multiple regression analysis.
The results showed that the mean score for the adherence to rehabilitation was 83.78 (SD = 16.26). Perceived self-efficacy and social support together predicted 56% of the variance in the adherence to rehabilitation (adj. R² = 0.56, p < .01). Perceived self-efficacy was the most predictive variable for the adherence to rehabilitation (β = 0.70, p < .01), followed by social support (β = 0.39, p < .01). Therefore, promoting the adherence to rehabilitation should focus on enhancing self-efficacy alongside providing social support.

Fri, 06 Dec 2024 00:00:00 +0700

This predictive correlational study aimed to investigate the positive aspect and its predicting factors among caregivers of older adults with dependency. The participants were 114 caregivers of older adults with dependency in Saraburi province who were recruited based on multi-stage cluster sampling. Data was collected by using 1) the demographic data questionnaire, 2) relationships between caregiver and older adult questionnaire, 3) perceived self-efficacy questionnaire, 4) social support questionnaire, 5) perceived caregiving burden questionnaire, and 6) positive aspect of caregiving questionnaire. The questionnaires no. 2 - 6 yielded Cronbach’s alpha of 0.86, 0.92, 0.89, 0.88 and 0.94 respectively. Descriptive statistics, percentage, mean, and standard deviation, and stepwise multiple regression were employed to analyze the data.
The results revealed that caregivers of older adults with dependency have high levels of positive aspect (Mean = 4.40, SD = 0.45). Stepwise multiple regression analysis demonstrated that social support, perceived self-efficacy, relationships between caregiver and older adult, and perceived caregiving burden together could explain 82.60% of the variance in positive aspect among caregivers of older adults with dependency (R² = .826, F = 129.289, p < .001). The most significant predicting factor was social support (b = .416, p < .01), followed by perceived self-efficacy (b = .255, p < .001), relationships between caregiver and older adult (b = .172, p < .01), and perceived caregiving burden (b = -.170, p < .05).
The results from this study provide useful information for relevant healthcare providers to create activities aimed at promoting positive aspect among caregivers of older adults with dependency by enhancing their social support, perceived self-efficacy, relationships between caregiver and older adult, and reduce the perceived burden.

Kritsada Chumvanichaya, Kanoklekha Suwannapong — Fri, 06 Dec 2024 00:00:00 +0700

Triage training is an essential component of emergency medical services and disaster response, where healthcare professionals are trained to assess and prioritize patients quickly and efficiently. This study aimed to develop immersive, interactive 3D learning materials using virtual reality technology to enhance the skills of sieve, sort, and start triage (VR-SSST) in mass casualty situations, and to test its feasibility. This study employs a research and development design composed of three phases: (1) content development and scenario design; (2) technical development and platform selection; and (3) pilot testing to gather feedback on feasibility. Thirty 2nd-year emergency medical technician students in academic year 2024 from the Naval Operational Medicine School, Naval Medical Department, Royal Thai Navy were recruited for testing VR-SSST. Data were collected using a questionnaire. Data analysis included calculating the content validity index, mean, and standard deviation.
The results show that the VR-SSST is a triage program that includes sieve, sort, and start triages, leveraging virtual reality technology to create a highly immersive and engaging learning experience. It involves the use of 3D simulations and environments to facilitate learning, allowing users to interact with and explore triage content. The content validity index was highly acceptable (CVI = 1). The feasibility of VR-SSST was rated at a high level (M = 4.49, SD = 0.88). The VR-SSST is a valuable tool with good content validity and high feasibility. Trainers can use VR-SSST as a tool for the triage training.

Effects of the Health Literacy Promotion Program on Health Literacy and Behaviors for Preventing Cannabis Use among Upper Primary School Children in Pathum Thani Province

Wikanda Wiriyanupappong — Tue, 17 Dec 2024 00:00:00 +0700

This quasi-experimental study used a two-group pretest-posttest design and aimed to compare the school-aged children's health literacy and the prevention behaviors for cannabis use between the experimental group who attended the health literacy program and the control group who attended the usual program. The sample consisted of 58 students studying in grades 3 - 6 from a school in Patum Thani province. The multi-stage sample method was implemented for sample selection. The samples were divided into two groups using a simple random sampling method, with 29 students per group and were matched to have equal qualifications in grade level, gender, age, academic performance, and history of cannabis use. The research instruments for the experimental process consisted of: (1) The health literacy promotion program; and (2) The use of animation clip about “Interesting Facts of Cannabis”. The research instruments for data collection process consisted of: (1) The health literacy questionnaire in preventing cannabis use; and (2) The behaviors for preventing cannabis use. Three experts checked the content validity of the two instruments. The index of Item-Objective Congruence (IOC) of both questionnaires was 1. The instrument reliability was examined using Cronbach's alpha coefficient, which was 0.82 and 0.77, respectively. The differences in health literacy scores in preventing cannabis use and preventive behaviors before and after the experiment were compared using a paired t-test and between the experimental and control groups using an independent t-test.
The results revealed that the health literacy and the preventing behaviors scores of the experimental group during the posttest were significantly higher than the pretest (p < .05).
Based on these findings, it is suggested that the health literacy promotion program could be integrated to the health and physical education program or the school and community health promotion program to prevent and solve the inappropriate cannabis use of the school-aged children.
