Comparative analysis among therapeutic modalities in ruptured hepatocellular carcinoma and identification of imaging predictors for survival.

BACKGROUND: Spontaneous rupture of hepatocellular carcinoma (rHCC) poses a life-threatening complication with a mortality rate of 25-75%. Treatment aims at achieving hemostasis and includes options such as trans-arterial embolization, perihepatic packing, and hepatic resection. The optimal treatment remains a subject of debate. Our retrospective review evaluates these treatments and investigates imaging's role in prognosis for rHCC patients. PURPOSE: We aimed to compare survival outcomes among rHCC patients who received transarterial embolization (TAE), surgery (perihepatic packing, hepatectomy), or best supportive care (BSC), while also identifying predictive imaging factors in these patients. MATERIALS AND METHODS: All patients diagnosed with rHCC and admitted to Maharaj Nakorn Chiangmai Hospital between January 2012 and December 2021 were included. We reviewed clinical features, imaging results, treatment modalities, and outcomes. In order to balance pretreatment confounders, inverse probability treatment weighting (IPTW) was employed. Flexible parametric survival regression was utilized to compare survival outcomes and identify imaging factors predicting the survival of rHCC patients. Hazard ratios (HR) and the difference in restricted mean survival time (RMST) were reported. RESULT: Among the 186 rHCC patients included, we observed 90-day and 1-year mortality rates of 64% and 84%, respectively. Both the TAE and surgery groups exhibited significantly lower 1-year mortality rates compared to BSC. The HR were 0.56 (95% CI 0.33-0.96) for TAE and 0.52 (95% CI 0.28-0.95) for surgery compared to BSC. Both the TAE and surgery also significantly extended the 1-yeaar life expectancy post-initial treatment when compared to BSC, with an RMST difference of + 55.40 days (95% CI 30.18-80.63) for TAE vs. BSC and + 68.43 days (95% CI 38.77-98.09) for surgery vs. BSC. The presence of active contrast extravasation and bleeding in both lobes were independent prognostic factors for 1-year survival. CONCLUSIONS: TAE and surgical treatments provide comparable survival benefits for rHCC patients, extending survival time by approximately 2 months compared to best supportive care. We strongly recommend active management for all rHCC patients whenever possible.

Incidence of venous thromboembolism and predictive ability of age-adjusted international prognostic index for prediction of venous thromboembolism in Asian patients with diffuse large B-cell lymphoma.

Diffuse large B-cell lymphoma (DLBCL) is one of the malignancies at high risk for the development of venous thromboembolism (VTE). We aimed to evaluate the incidence of VTE and the predictive ability of the age-adjusted international prognostic index (aaIPI) for the prediction of VTE among DLBCL patients. This was a retrospective cohort study including adult patients with newly diagnosed DLBCL. Differences in VTE occurrence within one year after diagnosis of DLBCL were estimated across aaIPI groups using the Kaplan-Meier model, Cox's model, and Gray's model with deaths regarded as competing events. Five hundred and ninety-one newly diagnosed DLBCL patients with a median age of 58 (range 16-93) years were included in this study. At a median follow-up time of 365 (range 2-365) days, VTE events were objectively diagnosed in 32 patients, giving a one-year cumulative incidence of VTE of 5.4% (95% confidence interval [CI], 3.7-7.6). Patients with aaIPI ≥ 2 had a significantly higher risk of VTE than patients with aaIPI < 2 (hazard ratio, 3.5; 95% CI, 1.6-7.8; p = 0.001 based on Cox's model and sub-distribution hazard ratio, 3.0; 95% CI, 1.3-6.7; p = 0.007 using Gray's model). The C-statistic of aaIPI was 0.65 (95% CI, 0.58-0.72). We demonstrated that the incidence of VTE in Asian DLBCL patients was not uncommon. The aaIPI was effective in determining the risk of VTE in DLBCL patients, even when including death as a competing event. aaIPI may be helpful in identifying patients at higher risk of VTE in DLBCL patients.

PREVALENCE AND PERSISTENCE OF HYPERTRANSMISSION DEFECTS OF VARIOUS SIZES IN EYES WITH INTERMEDIATE AGE-RELATED MACULAR DEGENERATION.

PURPOSE: To determine the prevalence and rate of persistence over 2 years of various-sized hypertransmission defects (hyperTDs) in eyes with intermediate age-related macular degeneration. METHODS: Retrospective analysis of optical coherence tomography data from consecutive intermediate age-related macular degeneration patients. Choroidal en face optical coherence tomography images were evaluated for the presence and number of hyperTDs of three different sizes based on greatest linear dimension (small, 63-124 µ m; medium, 125-249 µ m; large, ≥250 µ m) at baseline and at the 2-year follow-up. Interreader agreement was determined by Gwet's agreement coefficient. Disagreements between graders were resolved by the senior investigator to yield a single consensus for all cases. RESULTS: From 273 intermediate age-related macular degeneration eyes (247 patients), 72 and 76 hyperTD lesions were independently identified by two graders at baseline and overall agreement coefficient was 0.89 (95% CI, 0.86-0.93). After adjudication by the senior grader, the final consensus yielded 78 hyperTD lesions from 46 eyes (16.8%) of 42 patients (17.0%) in this study cohort. Among eyes with follow-up optical coherence tomography, 32 of 45 hyperTD lesions (71.1%) persisted. The rates of persistence were 100.0%, 72.7%, and 53.3% in large, medium, and small hyperTD sizes, respectively. CONCLUSION: HyperTDs were present in a significant proportion of intermediate age-related macular degeneration eyes. Acceptable interreader agreement was demonstrated in identifying hyperTD. Larger hyperTD lesions were more likely to persist over 2 years.

Survival analysis of older adults with dementia: predicting factors after unplanned hospitalization in Maharaj Nakorn Chiang Mai Hospital.

BACKGROUND: Hospitalization in individuals with dementia can be associated with negative and unintended outcomes. Research indicates that people with dementia experience more hospital admissions in comparison to individuals without dementia. This study aims to assess the survival time of individuals with dementia who experience unplanned hospitalization and examine the factors that are associated with mortality in this population. METHODS: This retrospective cohort study was conducted using data from older adults with dementia who survived unplanned hospitalizations at Maharaj Nakorn Chiang Mai Hospital between January 1, 2009, and December 31, 2016. The association between factors and mortality were analyzed using a multivariable Cox proportional hazards model. RESULTS: One hundred and eighty-one cases were included. The mean age of the study population was 80.07 (SD 7.49) years, and the majority were female (56.91%). The median survival time of the studied cohort was 3.06 years (95% CI 3.14-3.60). The multivariable analysis revealed that older age (aHR = 1.02, 95% CI 1.00-1.05), a diagnosis of mixed-type dementia (aHR = 3.45, 95% CI 1.17-10.14), higher Charlson comorbidity index score (aHR = 1.19, 95% CI 1.04-1.36), higher serum creatinine level (aHR = 1.35, 95% CI 1.10-1.66), insertion of endotracheal tube (aHR = 1.95, 95% CI 1.07-3.54), and readmission within 30 days (aHR = 1.88, 95% CI 1.18-2.98) were associated with an increased risk of mortality. CONCLUSIONS: We identified several notable predictors of mortality. Healthcare providers can use the findings of this study to identify patients who may be at higher risk of mortality and develop targeted interventions which may improve patient outcomes.

External Validation of the Charlson Comorbidity Index-based Model for Survival Prediction in Thai Patients Diagnosed with Dementia.

BACKGROUND: The Charlson Comorbidity Index (CCI) is commonly employed for predicting mortality. Nonetheless, its performance has rarely been evaluated in patients with dementia. This study aimed to examine the predictive capability of the CCI-based model for survival prediction in Thai patients diagnosed with dementia. METHODS: An external validation study was conducted using retrospective data from adults with dementia who had visited the outpatient departments at Maharaj Nakorn Chiang Mai Hospital between 2006 and 2012. The data obtained from electronic medical records included age, gender, date of dementia diagnosis and death, types of dementia, and comorbidities at the time of dementia diagnosis. The discriminative ability and calibration of the CCI-based model were estimated using Harrell's C Discrimination Index and visualized with calibration plot. As the initial performance did not meet satisfaction, model updating and recalibration were performed. RESULTS: Of 702 patients, 56.9% were female. The mean age at dementia diagnosis was 75.22 (SD 9.75) year-old. During external validation, Harrell's C-statistic of the CCI-based model was 0.58 (95% CI, 0.54-0.61). The model showed poor external calibration. Model updating was subsequently performed. All updated models demonstrated a modest increase in Harrell's C-statistic. Temporal recalibration did not significantly improve the calibration of any of the updated models. CONCLUSION: The CCI-based model exhibited fair discriminative ability and poor calibration for predicting survival in Thai patients diagnosed with dementia. Despite attempts at model updating, significant improvements were not achieved. Therefore, it is important to consider the incorporation of other influential prognostic factors.

Predictive Model of Recovery to Prefracture Activities-of-Daily-Living Status One Year after Fragility Hip Fracture.

Background and Objectives: Achieving prefracture functional status is a critical objective following a hip fracture, yet fewer than half of patients reach this milestone. The adoption of tools for assessing functional outcomes is increasingly recognized as essential for evaluating recovery following treatment for fragility hip fractures. We developed multivariable clinical prediction criteria to estimate the likelihood of patients regaining their prefracture activities-of-daily-living (ADL) status one year after sustaining a fragility hip fracture. Materials and Methods: A retrospective cohort of patients treated for fragility hip fractures at a university-affiliated tertiary care center between February 2017 and April 2019 served as the basis for developing and internally validating the clinical prediction criteria. We applied a multivariable fractional polynomial method to integrate several continuous predictors into a binary logistic regression model. Results: The study included 421 patients, 324 (77%) of whom reported regaining their prefracture activities-of-daily-living level one year after experiencing fragility hip fractures. Significant predictors, such as the prefracture Barthel index, EQ-VAS score, and treatment modality, were incorporated into the predictive model. The model demonstrated excellent discriminative power (AuROC of 0.86 [95% CI 0.82-0.91]) and satisfactory calibration. Conclusions: The predictive model has significant discriminative ability with good calibration and provides clinicians with a means to forecast the recovery trajectories of individual patients one year after a fragility hip fracture, which could be useful because prompt clinical decision-making is aided by this information. Patients and caregivers can also be counseled and encouraged to follow up with the medical activities and interventions deemed essential by doctors who used the prediction tool. Access to the model is provided through a web application. External validation is warranted in order to prove its applicability and generalizability.

The efficacy of induction treatment in Thai patients with lupus nephritis: Observational cohort analysis.

BACKGROUND: For active proliferative lupus nephritis (LN), intravenous cyclophosphamide (IVCYC) is a standard therapy whereby mycophenolate mofetil (MMF) is less effective than IVCYC, according to the clinical trials in non-Asians. In this observational study, the clinical outcomes will be compared among Thai patients. METHODS: We had analyzed 93 adult patients who underwent a renal biopsy for active proliferative LN confirmation between January 2013 and June 2021. The assessment of the response outcomes compared the induction treatment of IVCYC versus MMF. The primary endpoint had achieved complete remission (CR) at 24 weeks, while the secondary endpoint is overall remission (OR) and urine protein creatinine ratio (UPCR) changed over time. RESULTS: 93 LN patients were separated into two groups; 40 in IVCYC and 53 in MMF. In the 24th week, based on unadjusted analysis, patient had achieved CR 20.0% of IVCYC, whereas 28.3% of MMF had achieved CR. Unadjusted CR Risk difference was -0.08 (95% CI -0.26, -0.09, p-value = 0.351) and the adjusted CR risk difference was -0.19 (95% CI -0.42, 0.04, p-value = 0.098). The unadjusted OR risk difference was -0.06 (95% CI -0.26, 0.14, p-value = 0.553) while adjusted OR risk difference was -0.24 (95% CI -0.50, 0.02, p-value = 0.067). Unadjusted UPCR mean was -0.29 (95% CI -0.77, 0.17, p-value = 0.210) and adjusted UPCR mean was -0.27 (95% CI -0.88, 0.32, p-value = 0.366). CONCLUSIONS: The induction treatment with either IVCYC or MMF had similar efficacy in Thai LN patients. The decision of treatment should be taken by applying an individualized therapeutic strategy and balancing risks, costs, and benefits.

Reactive Neutrophilic Dermatoses in Adult-Onset Immunodeficiency due to Interferon-Gamma Autoantibody and Their Associated Factors.

BACKGROUND: Adult-onset immunodeficiency (AOID) due to interferon-gamma autoantibody is a rare, acquired immunodeficiency disease. Reactive neutrophilic dermatoses (RND), predominantly Sweet syndrome (SS), and generalized pustular eruption have been reported repeatedly. OBJECTIVES: The aims of this study were to describe the cutaneous manifestations in AOID patients and determine the incidence of RND and associated factors using a larger population size than have been previously reported. METHODS: A retrospective chart review of all confirmed AOID cases in Chiang Mai University Hospital from January 2006 to June 2020 was conducted. The demographics and characteristics of RND including type, onset, and laboratory information in every episode of cutaneous manifestations were collected. Generalized estimating equations of binary logistic regression were used to determine the indicators of RND. RESULTS: A total of 146 patients with confirmed AOID were identified. Of these, 57 cases (39%) developed at least one episode of RND. Thirteen cases (23%) of the patients experienced RND twice during the follow-up period. All recurrence of RND displayed the same cutaneous phenotype, with the exception of 2 cases who had both SS and generalized pustular eruption. Finally, 49 episodes of SS and 22 episodes of generalized pustular eruption were included in the analysis. All patients with RND had concomitant active opportunistic infections, of which most were non-tuberculous mycobacterium (NTM) infection. NTM infection (prevalence odds ratio [POR] 2.87), lymphadenopathy (POR 3.30) as well as lower serum alkaline phosphatase (ALP) level (POR 0.71 for every 100-unit increment in ALP) were found to be significantly associated with RND occurrence. CONCLUSIONS: 39% of our AOID patients experienced RND once during the course of the disease. Notable factors associated with RND occurrence were concomitant NTM infection, lymphadenopathy, and lower level of ALP.

Molecular-based classification of endometrial carcinoma in Northern Thailand: impact on prognosis and potential for implementation in resource-limited settings.

BACKGROUND: Endometrial carcinoma is molecularly categorized into four subgroups: polymerase-E exonuclease domain-mutant (POLE-mut), mismatch repair-deficient (MMR-d), p53-abnormal (p53-abn), and no specific molecular profile (NSMP). This classification scheme has been included into clinical recommendation for post-operative risk-based management, although there have been few Asian studies on this topic. The present study aimed to evaluate the prevalence and clinical outcomes of endometrial carcinoma using this classification in Northern Thailand and the feasibility of implementation in resource-limited settings. METHODS: Endometrial carcinomas from hysterectomy specimens were classified using immunohistochemistry for MMR proteins and p53, as well as POLE mutation testing. Clinicopathological variables and outcomes were analyzed. The costs of the molecular information-based approach were compared to those incurred by the conventional approach (without molecular classification). RESULTS: Of 138 patients, 52.9% in the NSMP subgroup, 28.2% were in the MMR-d, 13.8% in the p53-abn, and 5.1% in the POLE-mut. After adjusting for other variables, patients with POLE-mut showed the most favorable outcomes, while those with p53-abn had the poorest survival. When estimating the costs for post-operative management, the use of molecular classification resulted in a 10% increase over the conventional approach. However, the cost increased only by 1% if only POLE testing was used to identify patients for treatment omission. CONCLUSION: In Northern Thailand, endometrial carcinoma had comparable subgroup distribution and prognostic implications to previous reports, supporting the implementation of management guidelines that incorporate molecular information. In resource-limited settings, at least POLE mutation testing in early-stage patients should be considered.

Performance of the Matsumiya scoring system in cervical cancer patients with bone metastasis: an external validation study.

BACKGROUND: Accurate prognostic prediction of survival in cervical cancer patients with bone metastasis is important for treatment planning. We aimed to externally validate the Matsumiya scoring system using external patient data. METHODS: We collected a retrospective cohort of patients with cervical cancer diagnosed with bone metastasis at Chiang Mai University Hospital from 1st January 2007 to 31st December 2016. The Matsumiya score was composed of 5 predictors, including the presence of extraskeletal metastasis, ECOG performance status, history of previous chemo- or radiotherapy, the presence of multiple bone metastasis, and bone metastasis-free interval < 12 months. Harrell's C-statistics and score calibration plots were used to evaluate the score performance. We also reconstructed the development study to estimate apparent performance values for comparison during external validation. RESULTS: A total of 124 cervical cancer patients with bone metastasis were included in this study. The 13-, 26-, and 52-week survival probabilities in the validation study were 70.1%, 50.5%, and 25.7%, respectively. Several differences were identified between development and validation studies regarding clinical characteristics, case-mix, and predictor-outcome associations. Harrell's C-statistics in the development and validation study were 0.714 and 0.567. The score showed poor agreement between the observed and the predicted survival probabilities in the validation study. Score reweighting and refitting showed only modest improvement in performance. CONCLUSION: A prognostic scoring system by Matsumiya et al. performed poorly in our cohort of Thai cervical cancer patients with bone metastasis. We suggested that the score should be sufficiently updated before being used.

Prognostic factors for mycological cure in patients with onychomycosis caused by Neoscytalidium dimidiatum: A retrospective cohort study.

BACKGROUND: The prognostic factors for cure have been derived from cases of dermatophyte onychomycosis. However, there are limited studies in non-dermatophyte onychomycosis. Neoscytalidium dimidiatum is the common causative agents of non-dermatophyte onychomycosis which has proven to be recalcitrant to treatment. OBJECTIVE: This retrospective cohort study investigated mycological cure and prognostic factors in Neoscytalidium onychomycosis patients. METHODS: Patients aged 18 or older with newly diagnosed Neoscytalidium onychomycosis were enrolled. All patients were treated and followed up for at least 1 year. Mycological cure was analysed with Cox proportional hazard regression. The hazard ratios (HRs) of previously reported potential prognostic factors were included in univariable and multivariable stratified Cox regression analyses. RESULTS: From total 198 patients, mycological cure was achieved in 108 (54.6%) patients with a median of 490 (± SD 62.2) days. The poor prognostic factors for mycological cure were age ≥ 70 years (HR, 0.63; 95% CI, 0.41-0.97; p = .034); nail thickness ≥2 mm (HR, 0.20; 95% CI, 0.11-0.35; p < .001); and peripheral vascular disease (HR, 0.46; 95% CI, 0.28-0.77; p = .003). Combination therapy was associated with achieving a mycological cure (HR, 2.55; 95% CI, 1.49-4.38; p < .001). CONCLUSIONS: Approximately half of the patients with onychomycosis caused by Neoscytalidium dimidiatum achieved a mycological cure, with a median time to cure exceeding 1 year. Combined topical and systemic antifungal treatments yield a higher chance of mycological cure than monotherapies. Advanced age, nail thickness and peripheral vascular disease are obstacle factors to cure.

Minimal clinically important difference (MCID) and minimal detectable change (MDC) of Spinal Cord Ability Ruler (SCAR).

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To find minimal clinically important difference (MCID) and minimal detectable change (MDC) of Spinal Cord Ability Ruler (SCAR) in Thai participants with spinal cord injury (SCI). SETTING: Rehabilitation ward at Maharaj Nakorn Chiang Mai Hospital. METHODS: Data of individuals with SCI who were not diagnosed with central cord syndrome and were admitted for the first time for rehabilitation were analyzed. Upper extremities motor score, self-care and mobility items of Spinal Cord Independence Measure version III were collected and used to calculate SCAR difference between data on date of admission and discharge. MCID and MDC were calculated by distribution-based method and categorized for each subgroup according to SCI characteristics. RESULTS: From data of 311 individuals, MCID of SCAR is approximately 4 for individual with tetraplegia AIS A, B, C; and individual with AIS D at any level, and 2 for individual with paraplegia AIS A, B, C. MDC of SCAR should be 1 for individual with tetraplegia AIS A, B, C; and individual with AIS D at any level and 0.5 for individual with paraplegia AIS A, B, C. CONCLUSION: This study provides MCID and MDC of SCAR in each subgroup. These values could be used as a benchmark for clinicians and researchers to determine whether participant has significant improvement or not after receiving an intervention.

Performance of the Dutch clinical prediction rule for the ambulation outcome after spinal cord injury in a middle-income country clinical setting: an external validation study in the Thai retrospective cohort.

OBJECTIVE: To perform external geographic and domain validation of the clinical prediction rule (CPR) of the ambulation outcome of patients with traumatic spinal cord injury (SCI) originally developed by van Middendorp, et al. (2011) in Thais with traumatic and non-traumatic SCI. STUDY DESIGN: Retrospective cohort study. SETTING: A tertiary rehabilitation facility in Chiang Mai, Thailand. METHODS: A validation data set, including predictive (age and four neurological variables) and outcome (ambulation status) parameters was retrospectively collected from medical records of patients with traumatic and non-traumatic SCI admitted between December 2007 and December 2019. The performance of the original model was evaluated in both discrimination and calibration aspects, using an area under the receiver-operating characteristic curve (auROC) and calibration curves, respectively. RESULTS: Three hundred and thirty-three patients with SCI were included in the validation set. The prevalence of ambulators was 59% (197 of 333 participants). An auROC of 0.93 (95% CI 0.90-0.96) indicated excellent discrimination whereas the calibration curve demonstrated underestimation, especially in patients with AIS grade D. Performance of the CPR was decreased but acceptable in patients with non-traumatic SCI. CONCLUSIONS: Our external validation study demonstrated excellent discrimination but slightly underestimated calibration of the CPR of ambulation outcome after SCI. Regardless of the geographic and etiologic background of the population, the Dutch CPR could be applied to predict the ambulation outcome in patients with SCI.

Are There Differences in Pain Reduction and Functional Improvement Among Splint Alone, Steroid Alone, and Combination for the Treatment of Adults With Trigger Finger?

BACKGROUND: Steroid injection and splinting, which are commonly recommended nonsurgical treatments in adults with trigger finger, have been demonstrated to effectively relieve pain and improve function. However, to our knowledge, there have been no direct comparisons of pain relief and function improvement with splinting alone, steroid injection alone, or a combination of splinting and steroid injection in patients with this diagnosis. QUESTION/PURPOSE: Are there differences in pain reduction and functional improvement in adults with trigger finger treated with splinting alone, steroid injection alone, and a combination of splinting and steroid injection at 6, 12, and 52 weeks after the intervention? METHODS: Between May 2021 and December 2021, we treated 165 adult patients for trigger finger at an academic university hospital. Based on prespecified criteria, all patients we saw during that period were eligible, but 27% (45 of 165) were excluded because they had received a previous local corticosteroid injection (n = 10) or they had concomitant carpal tunnel syndrome (n = 14), first carpometacarpal joint arthritis (n = 3), osteoarthritis of the hand (n = 6), de Quervain disease (n = 3), multiple-digit trigger finger (n = 6), or pregnancy during the study period (n = 3). After screening, 120 patients were randomized to receive either splinting (n = 43), steroid injection (n = 40), or splinting plus steroid injection (n = 37). Patients were randomly assigned to the different treatments using computer-generated block randomization (block of six). Sequentially numbered, opaque, sealed envelopes were used in the allocation concealment process. Both the allocator and the outcome assessor were blinded. Splinting involved the patient wearing a fixed metacarpophalangeal joint orthosis in the neutral position at least 8 hours per day for 6 consecutive weeks. Steroid injection was performed using 1 mL of 1% lidocaine without epinephrine and 1 mL of triamcinolone acetonide (10 mg/mL) injected directly into the flexor tendon sheath. No patients were lost to follow-up or had treatment failure (that is, the patient had persistent pain or triggering with the trigger finger treatment and requested additional medical management including additional splinting, steroid injection, or surgery) at 6 or 12 weeks after the intervention, and at 52 weeks, there was no difference in loss to follow-up among the treatment groups. An intention-to-treat analysis was performed with all 120 patients, and a per-protocol analysis was conducted with 86 patients after excluding patients who were lost to follow-up or had treatment failure. Primary outcomes evaluated were VAS pain reduction and improvement in Michigan Hand Outcomes Questionnaire (MHQ) scores at 6, 12, and 52 weeks after the intervention. The minimum clinically important difference (MCID) values were 1 and 10.9 for the VAS and MHQ, respectively. RESULTS: There were no clinically important differences in VAS pain scores among the three treatment groups at any timepoint, in either the intention-to-treat or the per-protocol analyses. Likewise, there were no clinically important differences in MHQ scores at any timepoint in either the intention-to-treat or the per-protocol analyses. CONCLUSION: Splinting alone is recommended as the initial treatment for adults with trigger finger because there were no clinically important differences between splinting alone and steroid injection alone in terms of pain reduction and symptom or functional improvement up to 1 year. The combination of steroid injection and splinting is disadvantageous because the benefits in terms of pain reduction and symptom or functional improvement are not different from those achieved with steroid injection or splinting alone. LEVEL OF EVIDENCE: Level I, therapeutic study.

Outcomes of coronal pulpotomy on permanent first molars in children: a retrospective cohort study.

OBJECTIVES: To investigate the survival probability of permanent first molars (PFMs) after coronal pulpotomy (CP) using two outcome definitions: success-focused and functional survival-focused, and to identify factors influencing tooth survival. MATERIALS AND METHODS: A retrospective cohort study reviewing records of children undergoing CP with calcium silicate-based cements (CSCs) on PFMs. Each CP-treated PFM was classified as success, uncertain, failure, or censored. Survival probability was analyzed using Kaplan-Meier estimators. Success-focused definition considered failures and uncertain outcomes as events, while functional survival-focused definition considered only failures as events. Prognostic factors were analyzed using Cox regression analysis. RESULTS: Seventy-seven CP-treated PFMs with a follow-up period of 6-111 months. Using the success-focused definition (two failures and 12 uncertain outcomes as events), survival probabilities were 93.1% (95% CI 84.3-97.1%) at 12 months, 78.7% (95% CI 65.6-87.3%) at 36 months, and 74.9% (95% CI 59.5-89.0%) at 60-111 months. However, with the functional survival-focused definition, survival probabilities were 100% at 12 months and 96.6% (95% CI 86.9-99.1%) at 24-111 months. In multivariable analysis, proximal lesions increased failure risk compared to occlusal lesions (HR 17.17, 95% CI 2.18-135.31, p < 0.01), and resin composite restorations had higher failure risk than stainless steel crowns (HR 13.97, 95% CI 1.49-130.69, p < 0.05). CONCLUSIONS: CP using CSCs shows long-term survival potential as an alternative treatment for cariously exposed PFMs in children. CLINICAL RELEVANCE: Proximal lesions and resin composite restoration could contribute to the lower survival, indicating the need for careful consideration of restoration options and lesion location during treatment planning.

Meta-analysis and cost-effectiveness analysis of intranasal corticosteroid treatment in allergic rhinitis with ocular symptoms.

BACKGROUND: Intranasal corticosteroid (INCS) has a beneficial effect on ocular symptoms in allergic rhinitis (AR). To our knowledge, the cost-effectiveness of available INCS for AR with ocular symptoms is yet to be demonstrated. OBJECTIVE: To evaluate the cost-effectiveness of INCSs including Budesonide (BANS), Mometasone furoate (MFNS), Triamcinolone (TANS), and Fluticasone furoate (FFNS) on ocular symptoms associated with AR in the Thai context. METHODS: The percentage of effectiveness in improving total ocular symptoms score (TOSS) was derived from the result of a meta-analysis that estimated the SMD of each INCS treatment compared to placebo as clinical input parameters. A cost-effectiveness analysis based on a decision-tree model to assess one-year costs and outcomes from a Thai societal perspective. The outcomes were to compare incremental cost-effectiveness ratio (ICER). Probabilistic sensitivity analyses (PSA) were also conducted to capture parameter uncertainties. RESULTS: 13 eligible RCTs with a total of 3,722 patients with SAR were included in the analysis. The percentage of effectiveness of FFNS, MFNS, TANS, and BANS was 59.89%, 45.60%, 24.89%, and 16.00%, respectively. The ICER of FFNS, MFNS, and TANS is THB-6,539.92, 4,593.83, and 1,401.24 compared to BANS. CECA result showed the probability of using FFNS is considered cost-effective in 87.50% of cases from zero value followed by MFNS (0.80%), TANS (5.40%), and BANS (6.30%). With a threshold greater than THB20,000, FFNS is considered a cost-effective strategy. CONCLUSIONS: FFNS is a cost-effective option compared to alternative INCSs in Thailand for treating AR with ocular symptoms.

Effective Dose Range of Intrathecal Isobaric Bupivacaine to Achieve T5-T10 Sensory Block Heights for Elderly and Overweight Patients: An Observational Study.

Background and Objectives: The dose selection for isobaric bupivacaine determines the success of spinal anesthesia (SA). A dose higher than the optimal dose causes high SA, whereas an underdose leads to inadequate spread of cephalad. As it involves anatomical and physiological alterations, the dosing should be reduced with advancing age and body mass index values. Therefore, this study aimed to demonstrate the association between the isobaric bupivacaine dose and block height, and to determine the dose intervals of bupivacaine to achieve the T5-T10 sensory block with a low probability of high SA in elderly and overweight patients. Material and Methods: This retrospective observational study recruited 1079 adult patients who underwent SA with 0.5% isobaric bupivacaine from 2018 to 2021. The patients were divided into four categories: category 1 (age < 60, BMI < 25), category 2 (age < 60, BMI ≥ 25), category 3 (age ≥ 60, BMI < 25), and category 4 (age ≥ 60, BMI ≥ 25). The bupivacaine dose and sensory block height (classified into three levels: high (T1-T4), favorable (T5-T10), and low (T11-L2)) were recorded. Results: The sensory block level increased significantly with increasing doses of bupivacaine for patients in categories 1 and 2. The suggested dose ranges for the favorable block heights were 15-17 and 10.5-16 mg in patient categories 1-2 and 3-4, respectively. In these dose ranges, the probability range of high SA was 10-15%. Conclusions: The sensory block height following SA was associated with the bupivacaine dose in patients aged <60 years. Regardless of the BMI, the suggested dose ranges of 0.5% isobaric bupivacaine are 15-17 mg (3.0-3.4 mL) and 10.5-16 mg (2.1-3.2 mL) for patients aged <60 and ≥60 years, respectively.

Hormone replacement therapy in women and risk of carpal tunnel syndrome: a systematic review and metaanalysis.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common entrapment mononeuropathy. Menopausal status and/or estrogen level may play a role in CTS. The evidence regarding the association between hormone replacement therapy (HRT) in postmenopausal women and CTS is still conflicting. This meta-analysis aimed to investigate the association between carpal tunnel syndrome (CTS) and women using hormone replacement therapy (HRT). METHODS: A search was conducted in the PubMed/Medline, Scopus, Embase, and Cochrane databases, from their inception through July 2022. Studies which reported on the association between any type of HRT use and the risk of developing CTS in postmenopausal women compared to a control group were included. Studies which did not include a control group were excluded. Of the 1573 articles extracted from database searches, seven studies involving 270,764 women were included of which 10,746 had CTS. The association between CTS and HRT use was evaluated using the pooled odds ratio (OR) with a 95% confidence interval (CI) under random-effects modelling. Risk of bias in each study was assessed using the Newcastle-Ottawa Scale (NOS) and version 2 of the Cochrane tool for assessing risk of bias in randomized trials (RoB 2). RESULTS: HRT use showed no statistically significant association with a higher risk of CTS with pooled odds ratio (OR) 1.49, 95% confidence interval (CI) 0.99-2.23, and p = 0.06, although high heterogeneity among the studies was observed (I2 97.0%, Q-test p-value < 0.001). Subgroup analysis of groups in non-randomized controlled studies showed a significantly increased risk of CTS, while groups in randomized controlled studies showed a decreased risk of CTS (pooled OR 1.87, 95% CI 1.24-2.83 versus pooled OR 0.79, 95% CI 0.69-0.92, respectively) with the p-value of group difference < 0.001. The risk of bias in most of the included studies was estimated to be low. CONCLUSIONS: This meta-analysis supports the safety of using HRT in postmenopausal women with potential risk factors for CTS. LEVEL OF EVIDENCE: I, Prognosis. REGISTRATION: INPLASY (202280018).

Reference Database of Inner Retinal Layer Thickness and Thickness Asymmetry in Healthy Thai Adults as Measured by the Spectralis Spectral-Domain Optical Coherence Tomography.

INTRODUCTION: The study aimed to determine a reference database of the thickness and intraocular thickness asymmetry of total retina, retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), and inner plexiform layer (IPL) in healthy Thai subjects measured by the Spectralis spectral-domain optical coherence tomography. METHODS: This cross-sectional study recruited the healthy subjects age ≥18 years, having spherical refraction within ±6 diopters and cylindrical refraction ±3 diopters, from a hospital's personnel and the people visiting the ophthalmology department. Only 1 eye of each subject was randomly selected for an analysis. Macular images were obtained using posterior pole thickness scan protocol over a 24° × 24° area at the center of the fovea. The automated retinal thickness segmentation values of total retina and three inner retinal layers were calculated for the mean and the mean intraocular thickness difference between superior and inferior retinal hemispheres. The influence of age, gender, and axial length on thickness and thickness asymmetry of individualized retinal layer was evaluated. RESULTS: 252 subjects were included in study with a mean (SD) age of 46.7 (15.8) years, and 120 (47.6%) were males. According to the Early Treatment Diabetic Retinopathy Study map, the inner ring area was the thickest location of the total retina (range; 326.0-341.5 µm), GCL (range; 47.7-52.7 µm), and IPL (range; 39.9-42.1 µm), whereas the thickest location of RNFL was at the outer ring area (range; 18.8-47.5 µm). For posterior pole intraocular thickness asymmetry, the greatest mean ± SD difference was observed for total retina (9.0 ± 2.2 µm), followed by RNFL (9.9 ± 3.2 µm) and GCL (2.7 ± 0.6 µm), and the lowest mean difference was noted for IPL (2.4 ± 0.5 µm). The thickness and thickness asymmetry of each retinal layer were variably influenced by age, gender, and axial length; however, these factors had a minimal influence on the thickness asymmetry maps of GCL and RNFL. CONCLUSION: The reference database of the macular thickness and thickness asymmetry from this study would be beneficial in determining physiologic variations of the OCT parameters in the healthy Thai population.

Association between diabetes mellitus and risk of infection after trigger finger release: a systematic review and meta-analysis.

PURPOSE: To investigate the association between diabetes mellitus and risk of infection after trigger finger release. METHODS: Reports of adult trigger finger patients who had undergone trigger finger release that included details of patient diabetic status and post-surgery infections were included in the study. Reports of congenital trigger finger release and incomplete data on either diabetic status or infection after surgery were excluded. Search engines were PubMed, Scopus, the Cochrane Central Register of Controlled Trials, and Web of Science from inception to third December 2021. The risk of infection after trigger finger release was compared between diabetic and non-diabetic patients by evaluating the pooled risk ratio (RR) with a 95% confident interval (CI) under random effects modeling. Risk of bias in each study was assessed using Newcastle-Ottawa Scale (NOS). RESULTS: A total of 213,071 trigger finger patients described in seven studies were identified. Overall, patients with diabetes mellitus had a 65% higher risk of infection after trigger finger release compared to non-diabetic patients (RR 1.65; 95% CI, 1.39-1.95). Diabetes mellitus increased the risk of infection following trigger finger surgery in both young and old age groups as well as obese and non-obese patients who underwent open release surgery. The risk of bias in each of the included studies was estimated as moderate to high. CONCLUSION: Meta-analysis results demonstrated that diabetes mellitus increases the risk of infection after trigger finger release. Glycemic control and percutaneous rather than open surgery might be strategies to the reduce risk of infection after trigger finger release in diabetic patients.
