Introduction: The accurate measurement of the height of bedridden patients is difficult. Height assessment is required for the calculation of body mass index, which is crucial for determining the nutrition status of a patient. This study aimed to validate recumbent length measurement against the standing height measurement using soft and firm mattresses and to derive predictive equations to calculate the actual height of bedridden patients on mattresses with different firmness. Methods: Ninety-nine hospitalised participants (mean age 48.9±13.9 years; range 21–80 years) (49 men, 50 women) and 100 healthy participants (mean age 36.8±13.6 years; range 21–77 years) (50 men, 50 women) were recruited. Standing height was measured using a stadiometer. Recumbent length was measured using a 2 metre long measuring tape. Hospitalised participants lay on soft mattress and healthy participants on firm mattress. Results: Using Bland–Altman plot, 96% of hospitalised participants using soft mattress were within 2.5±2.7 cm (mean±2SD) whereas 97% of healthy participants using firm mattress were within 2.1±2.1 cm. The regression equation developed using firm mattress was Standing height (cm) = 0.993 x Recumbent length – 0.943; (r2=0.982). The regression equation developed using soft mattress was Standing height (cm) = 1.012 x Recumbent length – 4.477; (r2=0.981). Conclusion: We concluded that recumbent length is a valid clinical tool to estimate standing height. Standing height can be estimated from the predictive equations developed for patients lying on soft or firm mattresses.

INTRODUCTIONMalnutrition is common among hospitalised patients, with poor follow up of nutrition support post-discharge. Published studies on the efficacy of ambulatory nutrition support (ANS) for malnourished patients post-discharge are scarce. The aims of this study were to evaluate the rate of dietetics follow-up of malnourished patients postdischarge, before (2008) and after (2010) implementation of a new ANS service, and to evaluate nutritional outcomes post-implementation.

MATERIALS AND METHODSConsecutive samples of 261 (2008) and 163 (2010) adult inpatients referred to dietetics and assessed as malnourished using Subjective Global Assessment (SGA) were enrolled. All subjects received inpatient nutrition intervention and dietetic outpatient clinic follow-up appointments. For the 2010 cohort, ANS was initiated to provide telephone follow-up and home visits for patients who failed to attend the outpatient clinic. Subjective Global Assessment, body weight, quality of life (EQ-5D VAS) and handgrip strength were measured at baseline and five months post-discharge. Paired t-test was used to compare pre- and post-intervention results.

RESULTSIn 2008, only 15% of patients returned for follow-up with a dietitian within four months post-discharge. After implementation of ANS in 2010, the follow-up rate was 100%. Mean weight improved from 44.0 ± 8.5 kg to 46.3 ± 9.6 kg, EQ-5D VAS from 61.2 ± 19.8 to 71.6 ± 17.4 and handgrip strength from 15.1 ± 7.1 kg force to 17.5 ± 8.5 kg force; P <0.001 for all. Seventy-four percent of patients improved in SGA score.

CONCLUSIONAmbulatory nutrition support resulted in significant improvements in followup rate, nutritional status and quality of life of malnourished patients post-discharge.

INTRODUCTIONSingapore is the first Asian country to establish a nationwide breast screening programme, but our breast cancer screening uptake lags behind the Western countries. This survey focused on the subject of screening mammography, to assess the reasons for non-attendance and explore ways to improve our screening uptake.

MATERIALS AND METHODSFemales ≥21 years old were approached at primary healthcare clinics to participate in this survey, which questioned their knowledge, perception and expectations of breast screening.

RESULTSThere were 1011 respondents. Of the 740 respondents ≥40 years old, 332 respondents (45.5%) went for regular mammogram screening. Women who had lower household incomes [<$2000 (OR 0.49; 95% CI, 0.28 to 0.85); $2000 to $3999 (OR 0.59; 95% CI, 0.36 to 0.97)], did not know anyone with breast cancer (OR 0.62; 95% CI, 0.42 to 0.92), did not perform breast self-examination (OR 0.42; 95% CI, 0.28 to 0.62), had lower knowledge scores (OR 0.34; 95% CI 0.22 to 0.51), did not attend other health screening (OR 0.14; 95% CI, 0.05 to 0.41), and perceived mammography as embarrassing (OR 0.55; 95% CI, 0.31 to 0.96), were less likely to attend mammographic screening. Many did not know that screening is for the asymptomatic (51.2%), or the age to start screening (46.3%). Most respondents preferred to have their mammograms in the polyclinics (62.2%) and their screening reminders to be through short messaging service (SMS) (46.0%).

CONCLUSIONOur results show the current influences on Singapore women's screening practices, and also revealed that their understanding of mammogram screening is limited despite a high level of breast cancer awareness.

Vestibular schwannomas (VSs) are the most common cerebellopontine tumors. The natural history of smaller-sized VSs (<30 mm) has been well-studied, leading to the recommendation of a “watch and wait” approach. However, large VSs (>30 mm) have not been extensively studied, mainly because of their rarity. As such, most patients are conventionally offered surgery which carries a significant risk of neurological morbidity. Here, we report a case of a giant VS (>40 mm) in a 30-year-old man who regressed spontaneously. He was lost to follow-up for 18 years and, upon re-presentation, the symptomatology drastically improved and repeat imaging demonstrated a marked reduction in tumor size. Referring to similar cases in other studies, we postulate that most large and giant VSs undergo a phase of growth and stasis, followed by regression due to shifts in the balance between tumorigenic and regressive factors. Taken together with emerging molecular data, further studies are required to better understand the history of large and giant VSs to shape more personalized treatment options. This potentially includes non-operative management as a tenable option.

INTRODUCTIONBreast milk fatty acids play a major role in infant development. However, no data have compared the breast milk composition of different ethnic groups living in the same environment. We aimed to (i) investigate breast milk fatty acid composition of three ethnic groups in Singapore and (ii) determine dietary fatty acid patterns in these groups and any association with breast milk fatty acid composition.

MATERIALS AND METHODSThis was a prospective study conducted at a tertiary hospital in Singapore. Healthy pregnant women with the intention to breastfeed were recruited. Diet profile was studied using a standard validated 3-day food diary. Breast milk was collected from mothers at 1 to 2 weeks and 6 to 8 weeks postnatally. Agilent gas chromatograph (6870N) equipped with a mass spectrometer (5975) and an automatic liquid sampler (ALS) system with a split mode was used for analysis.

RESULTSSeventy-two breast milk samples were obtained from 52 subjects. Analysis showed that breast milk ETA (Eicosatetraenoic acid) and ETA:EA (Eicosatrienoic acid) ratio were significantly different among the races (P = 0.031 and P = 0.020), with ETA being the highest among Indians and the lowest among Malays. Docosahexaenoic acid was significantly higher among Chinese compared to Indians and Malays. No difference was demonstrated in n3 and n6 levels in the food diet analysis among the 3 ethnic groups.

CONCLUSIONSDifferences exist in breast milk fatty acid composition in different ethnic groups in the same region, although no difference was demonstrated in the diet analysis. Factors other than maternal diet may play a role in breast milk fatty acid composition.

Background: This study analyzed the practice of dental medical dispute prevention rules of dental hygienists to present an improvement plan for improving perceived importance and practice and provide data for the development of effective medical dispute prevention programs. Methods: A self-administered questionnaire survey was conducted targeting dental hygienists who were providing assistance at dental hospitals and dental clinics in Seoul and Gyeonggi-do regions from March 22 to April 28, 2022. The questionnaire collected from 273 dental hygienists consisted of eight questions on general characteristics, 30 questions on medical dispute experience, and 14 questions on medical dispute prevention. Results: Complaints showed a high experience rate in ‘Consultation & reservation’, medical disputes in ‘Patient handling (unkind) related’, and ‘Prosthesis installation and cement removal’. In both the importance and practice of medical dispute prevention rules, Preservation of medical records and other medical-related data’ was high, and ‘Management of patients on standby for a long time’was low in terms of practice. ‘Lack of time’ and ‘Lack of manpower’ were cited as reasons for not resolving dental treatment disputes. The importance of dental dispute prevention rules was found to be significant according to age and position, and it was also found to affect the level of practice. Conclusion Seventy-six-point six percent of the respondents said that education on the prevention of medical disputes was necessary, although they lacked recognition of prevention rules compared to their perceptions and experiences. This study suggested specifying prevention rules in dental hygiene subjects and expanding education, improvement of dental treatment system, revise the law on the range of work to improve the recognition and practice of prevention rules.

BACKGROUNDToll like receptor (TLR) 9 has been shown to play a crucial role in the pathogenesis of systemic lupus erythematosus (SLE) in animal models. Its pathogenic role in human SLE, however, was poorly elucidated. This study was performed to investigate the role of TLR9 involved in the aberrant signaling pathway and its correlation with disease activity in SLE.

METHODSmRNA level of TLR9 and interferon (IFN) regulatory factor 5 (IRF5) in peripheral blood mononuclear cells (PBMCs) were determined by real-time polymerase chain reaction (PCR). IFN-a expression was measured in the serum of the SLE patients by enzyme-linked immunosorbent assay (ELISA).

RESULTSTLR9 expression was significantly higher in SLE patients than that in health controls (P = 0.011). SLE patients with positive anti-dsDNA antibody had significantly higher expression of TLR9 than that with negative anti-dsDNA antibody (P = 0.001). TLR9 expression was positively correlated with fever (P = 0.017), alopecia (P = 0.046), safety of estrogens in lupus erythematosus national assessment SLE disease activity index (SELENA-SLEDAI) score (r(s) = 0.385, P = 0.003), and the level of IRF5 (r(s) = 0.35, P = 0.027) and IFN-a (r(s) = 0.627, P = 0.001) in SLE patients.

CONCLUSIONTLR9 is associated with SLE disease activity and might be involved in the IFN-a pathway of SLE.

INTRODUCTION: This study aimed to assess understanding of the potential risks associated with medical imaging among caregivers and adolescent patients in a paediatric emergency department (PED) in Singapore. METHODS: A prospective convenience sample survey was performed involving adolescents and caregivers presenting to our PED from December 2015 to May 2016. The questionnaire examined demographic data, knowledge of imaging procedures and radiation risks, and expectations regarding information provided about medical radiation. RESULTS: A total of 349 questionnaires were returned (caregivers 82.5%, adolescents 17.5%). A mean of 6.2 ± 2.4 (out of 11) questions were correctly answered. Those who had tertiary education fared better than those who did not (36.4% vs. 17.2% scoring above the mean, p = 0.001). Age, gender, history of previous imaging and imaging performed during the visit did not affect the score. Two-thirds of the participants did not associate medical radiation with any negative lifetime risk of cancers or know that different scans entailed differing amounts of radiation. Most were unaware that the radiation dose in medical imaging is adjusted to a child's size. Among patients who underwent imaging, 90.1% received explanations on the need for scans, and 26.5% were informed of the risks involved. Almost all participants wished to be informed of imaging indications and risks. More preferred to learn this from physicians (75.6%) or technicians (51.6%) rather than through educational pamphlets (34.4%) or Internet resources (22.9%). CONCLUSION Awareness regarding medical radiation needs to be improved in our patient population. A mismatch exists between caregiver expectations and the actual procedure of disclosure of the risk associated with radiation.
