Enhanced technique of dural closure using autologous fat graft and Gelfoam for effective management of dural tear following interlaminar endoscopic lumbar spine surgery.

BACKGROUND: Incidental dural tears are common complications in lumbar spine surgery, particularly in endoscopic procedures where primary closure via suturing is challenging. The absence of a standardized approach for dural closure in endoscopic spine surgery necessitates exploring alternative techniques. OBJECTIVE: This study introduces a surgical technique for dural closure utilizing fat graft and Gelfoam, offering an effective alternative to standard approaches in endoscopic spine surgery. METHODS: Surgical data from patients who underwent interlaminar endoscopic discectomy or stenosis decompression at Lerdsin Hospital from October 2014 to October 2021 were analyzed. RESULTS: Among 393 cases, dural tears occurred in 2% (8 patients). Our technique achieved successful closure in all these cases, with no incidents of cerebrospinal fluid leakage or wound complications. The majority of patients showed favorable clinical outcomes, except for one case involving concomitant nerve root injury. CONCLUSION: This study demonstrates that using fat graft and Gelfoam for dural closure is a simple, reliable, and safe technique, particularly effective for challenging-to-repair areas in interlaminar endoscopic lumbar spine surgery.

Exploring hospital practice types and their impact on glomerular pathologic patterns: Insights from the largest kidney biopsy cohort in Thailand.

BACKGROUND: This study aims to investigate the influence of different kidney biopsy practices on the prevalence of glomerular pathologic patterns in the largest kidney biopsy registry in Thailand. METHODS: We conducted a retrospective review of kidney biopsy records from the period between 2000 and 2014. The records were obtained from 2 major institutions: King Chulalongkorn Memorial Hospital, a large university-based hospital, and the Kidney Center Bangkok Hospital, which provides pathology services to hospitals throughout Thailand. The study included native kidney biopsies from all provinces in Thailand, excluding paediatric patients, kidney transplant recipients, and cases of inadequate and repeated biopsies. Patient demographics, indications for biopsy, and final glomerular diagnoses were compared across different hospital practice settings: university (UVH), private (PVH) and public (PBH). RESULTS: A total of 5893 eligible native kidney biopsies were identified from a pool of 7005 biopsies conducted over a 15-year period in 25 provinces throughout Thailand. The 3 most common indications for biopsy were suspected kidney involvement in systemic lupus erythematosus (SLE) (29%), nephrotic syndrome (NS) (29%), and acute glomerulonephritis (AGN)/rapidly progressive glomerulonephritis (RPGN) (13%). The leading indication for biopsy differed across practice types, with suspected kidney involvement in SLE being the primary indication in UVH, while NS took precedence in both PBH and PVH practices. Notably, UVH performed fewer kidney biopsies for asymptomatic urinary abnormalities and diabetes-related indications compared with PVH and PBH. The leading glomerular diagnoses correlated with the biopsy indications, with lupus nephritis (LN) being the most common diagnosis in UVH and PBH practices, whiles immunoglobulin A nephropathy was the predominant diagnosis in PVH practice. CONCLUSION: Hospital practice types significantly impact the prevalence of glomerular pathologic diagnosis patterns in kidney biopsy data, highlighting the importance of considering this influence in epidemiological comparisons.

Constipation and clinical outcomes in peritoneal dialysis: Results from Thailand PDOPPS.

BACKGROUND: Patient-reported outcome measures (PROMs) are widely recognized as valuable predictors of clinical outcomes in peritoneal dialysis (PD). Our study aimed to explore the connections between patient-reported constipation and clinical outcomes. METHODS: We assessed constipation in patients across 22 facilities participating in the Thailand Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) from 2014 to 2017. Constipation diagnosis utilized objective assessment tools such as the Bristol stool form scale (BSFS) and a self-reported questionnaire known as the constipation severity score (CSS). The BSFS is a 7-level scale that visually inspects feces based on texture and morphology, while the CSS measures constipation duration and severity using a 5-point Likert scale for various factors. We employed Cox proportional hazards model regression to determine the associations between constipation and clinical outcomes, including mortality, hemodialysis (HD) transfer and peritonitis. RESULTS: Among 975 randomly selected PD patients from 22 facilities, 845 provided written informed consent, and 729 completed CSS questionnaire. Constipation was prevalent in the PD population (13%), particularly among older patients, those who were caregiver dependent, had diabetes and poorer nutritional status (indicated by lower time-averaged serum albumin, potassium, creatinine and phosphate concentrations). Twenty-seven percent of which experiencing symptoms of constipation for over a year. Notably, self-reported constipation at baseline was significantly associated with a shorter time to first peritonitis and higher rates of peritonitis and death. However, no significant association was found between constipation and HD transfer after adjusting for various factors, including age, gender, PD vintage, comorbidities, shared frailty by study sites and serum albumin. CONCLUSION: Patient-reported constipation independently correlated with increased risks of peritonitis and all-cause mortality, though no such correlation was observed with HD transfer. These findings underscore the need for further investigation to identify effective interventions for constipation in PD patients.

Pain improvement and reoperation rate after full-endoscopic decompression for lateral recess stenosis: a 10-year follow-up.

PURPOSE: To share long-term clinical outcomes and our experience with full-endoscopic interlaminar decompression (FEI) for lateral recess stenosis (LRS). METHODS: We included all patients who underwent FEI for LRS from 2009 to 2013. VAS for leg pain, ODI, neurological findings, radiographic findings, and complications were analyzed at one week, one month, three months, and one year postoperation. The telephone interview for local patients with simple questions was done approximately ten years after the operation. International patients receive an email with the same questionnaire as local patients during the same follow-up period. RESULTS: One hundred and twenty-nine patients underwent FEI for LRS with complete data during 2009-2013. Most of the patients (70.54%) had LRS radiculopathy for less than one year, mainly L4-5 (89.92%), followed by L5-S1 (17.83%). Early outcomes three months after surgery showed that most patients (93.02%) reported significant pain relief, and 70.54% reported no pain at their ODI scores were significantly reduced from 34.35 to 20.32% (p = 0.0052). In contrast, the mean VAS for leg pain decreased substantially by 3.77 points (p < 0.0001). There were no severe complications. At ten years of follow-up, 62 patients responded to the phone call or email. 69.35% of the patients reported having little or no back or leg pain, did not receive any further lumbar surgery, and were still satisfied with the result of the surgery. There were six patients (8.06%) who underwent reoperation. CONCLUSION: FEI for LRS was satisfactory at 93.02%, with a low complication rate during the early follow-up period. Its effect seems to decline slightly in the long term at a 10-year follow-up. 8.06% of the patients subsequently underwent reoperation.

Social restriction versus herd immunity policies in the early phase of the SARS-CoV-2 pandemic: A mathematical modelling study.

BACKGROUND: Two main strategies to cope with the coronavirus disease 2019 (COVID-19) pandemic-lockdown (social restriction) and non-lockdown (herd immunity plan)-have been implemented in several countries. OBJECTIVE: This study aims to statistically compare the outcomes of the two strategies, represented by data from Thailand and Sweden, respectively. METHODS: Data for COVID-19 pandemic control from Thailand, representing social restriction, versus data from Sweden, representing the herd immunity plan, collected from January 13 to May 31, 2020, were analyzed by using the SIR (susceptible, infectious, recovered) model. RESULTS: The SIR model analysis demonstrated a beneficial effect of each model on the attenuation of the mortality rate, with lower mortality in social restriction and shorter overall pandemic duration in the herd immunity plan. However, the herd immunity plan demonstrated a higher mortality rate than social restriction (46.9% versus 1.9%) despite the later entry of the virus in Sweden. When the SIR model was used for predicting the COVID-19 status, Sweden was shown to likely end its COVID-19 epidemic earlier than Thailand (268 vs. 368 days). With the nonlinear estimation, at least one log difference between total confirmed cases versus active cases could be used as an indicator for relaxation of the lockdown policy in Thailand. CONCLUSIONS: Both the social restriction and herd immunity plans are beneficial for COVID-19 pandemic control in terms of the amelioration of pandemic mortality. The cumulative number of total recovered cases might be a potential parameter that could be used for determining the policy direction for COVID-19 control.

Intra-Articular Facet Joint Injection of Normal Saline for Chronic Low Back Pain: A Systematic Review and Meta-Analysis.

Objective: This systematic review and meta-analysis compared the patient-reported outcomes of intra-articular facet joint injections of normal saline and selected active substances to identify a more effective agent for treating subacute and chronic low back pain (LBP). Methods: The PubMed, Embase, Scopus, Web of Science, and CENTRAL databases were searched for randomized controlled trials and observational studies published in English. A research quality assessment was performed using ROB2 and ROBINS-I. A meta-analysis was conducted using a random-effects model, and the mean differences (MD) with 95% confidence intervals (CI) in efficacy outcomes, including pain, numbness, disability, and quality of life, were assessed. Results: Of the 2467 potential studies, 3 were included (247 patients). The active substances and normal saline had similar therapeutic effects on pain within 1 h, after 1-1.5 months, and after 3-6 months, with MD and 95% CI of 2.43 and -11.61 to 16.50, -0.63 and -7.97 to 6.72, and 1.90 and -16.03 to 19.83, respectively, as well as on the quality of life after 1 and 6 months. Conclusions: The short- and long-term clinical effects of intra-articular facet joint injections of normal saline are comparable to those of other active substances in patients with LBP.

Effect of multiple analgesic pathways including local infiltration analgesia, peripheral nerve blocks, and intrathecal morphine for controlling pain after total knee arthroplasty.

BACKGROUND: We questioned whether the triple analgesic pathways procedure via local infiltration analgesia (LIA), peripheral nerve blocks, and intrathecal morphine (ITM) is superior to LIA only for controlling pain after Total Knee Arthroplasty (TKA). METHODS: This retrospective study included 192 primary TKA patients. Group A (76 patients) received LIA only, Group B (61 patients) had ITM, adductor canal block and LIA, while Group C (55 patients) received ITM, femoral nerve block and LIA. A propensity score-matched analysis was used to compare visual analog scales (VAS) for pain intensity, total amount of morphine consumption (TMC), angle of knee flexion, and length of hospital stay (LHS). RESULTS: Group A showed significantly higher VAS than Group B at 12 h (4.27 ± 2.70 vs 2.42 ± 2.35) and 18 h (4.24 ± 2.35 vs 2.18 ± 2.02), and significantly higher than Group C at 6 h (3.46 ± 3.07 vs 0.60 ± 1.50), 12 h (4.27 ± 2.70 vs 0.89 ± 1.48), and 18 h postoperative (4.24 ± 2.35 vs 1.82 ± 2.18). However, the VAS of Group C and B converged to equalize with Group A after 12 and 18 h, respectively. The TMC at 48 h postoperative of Group A was higher than that of Group B (p < 0.01). Nevertheless, there was no difference between groups in terms of knee flexion and LHS, except the LHS of Group B was longer than Group A (p = 0.04). CONCLUSION: Triple analgesic pathways could provide a better initial analgesic profile. However, the pain seems to be rebound after resolution of nerve block and ITM, with potentially longer LHS.

Peritoneal dialysis care during the COVID-19 pandemic, Thailand.

PROBLEM: The coronavirus disease 2019 (COVID-19) pandemic could affect health service provision of less urgent interventions, such as peritoneal dialysis for chronic kidney disease patients. APPROACH: To assess how peritoneal dialysis centres in Thailand adapted their provision of care, we invited medical directors and peritoneal dialysis managers to respond to an online survey on 1 July 2021. We asked whether they had modified or deferred their training, catheter insertion or removal, intravenous supplements, follow-up and home visits, and workload. LOCAL SETTING: Patients needing dialysis receive peritoneal dialysis free of charge in Thailand. As of 31 December 2020, 240 peritoneal dialysis centres in Thailand have provided care to 32 284 patients. RELEVANT CHANGES: At 24.6% (29/118) of centres, educational sessions for patients were modified. Catheter insertion continued at 71.9% (82/114) of centres. Few facilities (19.7%; 23/117) continued to perform peritoneal equilibration tests as usual. On-site intravenous injections were mostly transferred to health centres close to the patients' homes. Most centres reduced their outpatient follow-up visits (51.7%; 61/118) and stopped visiting patients at home (66.9%; 79/118). Peritoneal dialysis nurses reported an increased workload at 62.7% (74/118) of centres, and in many instances (66.1%; 78/118) were providing nursing care to COVID-19 patients and administering COVID-19 vaccines. LESSONS LEARNT: Health-care providers altered clinical care activities to protect their patients from COVID-19. However, further evidence is needed on the consequences of such alteration in care. To prepare for future pandemics, actors need to explore nonconventional peritoneal dialysis care as well as financial and nonfinancial incentive mechanisms for such care.

Spiritual well-being and its relationship with patient characteristics and other patient-reported outcomes in peritoneal dialysis patients: Findings from the PDOPPS.

BACKGROUND: Spiritual well-being (SWB), an individual's understanding of the meaning and purpose of life, may help patients with chronic or terminal illnesses cope with their diseases. This study aimed to assess SWB in patients on peritoneal dialysis (PD), as well as its relationship with patient characteristics and patient-reported outcomes (PRO). METHODS: The data were obtained from questionnaires that formed part of the PD Outcomes and Practice Patterns Study (PDOPPS). Measures used in this study were SWB scores derived from the WHO quality of life, spirituality, religiousness and personal beliefs (WHOQOL-SRPB) tool including 32 items from eight facets; physical (PCS) and mental component summary (MCS) scores of the 12-Item Short-Form Health Survey (SF-12), Center of Epidemiologic Studies Depression Scale-10 (CES-D-10) scores, burden of kidney disease scores and functional status scores. RESULTS: Overall, 529 out of 848 participants (62%) completely responded to the questionnaires and were included in the analysis. Over two-thirds of PD patients (70%) had moderate or higher SWB scores. The SWB scores were significantly lower in patients with age >65 years and unemployed status. SWB scores positively correlated with higher PCS, MCS, burden of kidney disease scores and functional status scores, while negatively correlated with depression scores by CES-D-10 scale. Patients who reported significant depressive symptoms (CES-D-10 score ≥ 10) had significantly lower SWB scores. CONCLUSION: Better SWB was significantly associated with better health-related QOL (HRQOL) and the absence of depressive symptoms. SWB may be an essential consideration in the delivery of high-quality PD.

Additional Peripheral Nerve Block to Periarticular Injection Has No Benefit for Patients Undergoing TKA: A Factorial Propensity Score-Matched Analysis Comparing Four Multimodal Analgesic Techniques.

BACKGROUND: Controversy remains over what and how many analgesic techniques are required as the most effective multimodal pain regimen in total knee arthroplasty (TKA). This study aimed to evaluate the effect of additional analgesic methods combined with periarticular injection (PAI) analgesia for TKA. METHODS: Using retrospective cohort data, patients undergoing TKA with spinal anesthesia and PAI were divided into 4 groups. Group A (control) comprised 66 patients; group B (73 patients) had additional adductor canal block; group C (70 patients) obtained additional femoral nerve block, and group D (73 patients) received additional adductor canal block and intrathecal morphine. Propensity score matching was applied to compare visual analog scale (VAS) for pain intensity, cumulative morphine use (CMU), knee flexion angle, straight leg raise, length of hospital stay, and postoperative nausea and vomiting. RESULTS: There was no significant difference regarding VAS and morphine use, when either group B or C was compared with group A. Group D had significantly lower VAS than groups A, B, and C during the first 24 hours after surgery and required significantly less CMU than groups A and B. However, the pain score of group D increased afterward, with significantly longer length of hospital stay than groups A and B. There was no difference in straight leg raise among the groups. CONCLUSION: Additional peripheral nerve block to PAI provides no benefit for patients undergoing TKA. Adjuvant intrathecal morphine could significantly reduce the VAS and CMU in the acute postoperative period; however, rebound pain with prolonged hospital stays was observed.

Hyperextension following two different designs of fixed-bearing posterior-stabilized total knee arthroplasty.

PURPOSE: Hyperextension after total knee arthroplasty (TKA) is related to worse functional outcomes. Among the reported predictive factors, it is unclear whether prosthesis design affects postoperative hyperextension. Hence, our objectives were to (1) compare time-dependent changes of the extension angle following multi-radius (MR) and single-radius (SR) TKA and (2) assess predictive factors for the hyperextension. METHODS: In this study, consecutive 136 MR TKAs and consecutive 71 SR TKAs performed by a single surgeon were reviewed. The extension angle was evaluated by digitized full-extension lateral radiographs at preoperative, 3 months and at 1 and 2 years after TKA. A positive value was defined as hyperextension. A multiple regression analysis was used to determine predictive factors for the extension angle and the risk of hyperextension > 5°. RESULTS: The postoperative extension angle of both groups gradually increased during the first 2 years and the SR group finally progressed with 4.04° greater extension than the MR group (p < 0.01). The incidence of hyperextension > 5° in the SR group was 18.3% and for the MR group, 7.4% (p = 0.02). However, the Oxford knee scores was nonsignificant different between the groups (p = 0.15). Preoperative extension angle, sagittal femoral component angle (SFA) and SR prosthesis were predictive factors for the extension angle at 2 years after TKA and were also associated with hyperextension > 5°. CONCLUSIONS: The extension angle of the SR group became significantly more extended than that of the MR group during the first two years after TKA. Hence, ideal extension position immediately after SR TKA may be different from that of the MR TKA prosthesis. The preoperative extension angle, SFA and SR prosthesis were factors that were associated with postoperative hyperextension.

Intersphincteric Exploration With Ligation of Intersphincteric Fistula Tract or Attempted Closure of Internal Opening for Acute Anorectal Abscesses.

BACKGROUND: Acute anorectal abscesses of cryptoglandular origin are commonly managed by incision and drainage, which results in fistula development in up to 73% of cases, requiring subsequent definitive fistula surgery. However, given that fistula tracts may already be present at the initial presentation, primary closure of the tract as secondary prevention of fistula formation, using ligation of intersphincteric fistula tract, may be useful. OBJECTIVE: This study aims to examine the feasibility and outcomes of performing intersphincteric exploration with ligation of intersphincteric fistula tract or attempted closure of internal opening for acute anorectal abscesses. DESIGN: This is a retrospective study of patients with acute anorectal cryptoglandular abscesses who underwent surgery between January 2014 and December 2016. SETTINGS: The patients were treated at a tertiary referral center in Thailand. PATIENTS: Eighty-six patients with acute anorectal abscesses without previous surgery were included. INTERVENTIONS: Intersphincteric dissection was performed. Further surgical intervention was dependent on the intersphincteric findings. MAIN OUTCOME MEASURE: The main outcome measure was the 90-day healed rate. RESULTS: Of the 86 patients, 3 had low intersphincteric abscesses, 26 had low transsphincteric abscesses, 25 had anterior high transsphincteric abscesses, 27 had posterior high transsphincteric abscesses, and 5 had high intersphincteric abscesses. Ligation of intersphincteric fistula tract was successfully performed in 66 patients with an identifiable intersphincteric tract. Intersphincteric exploration with attempted closure of the internal opening was performed in the remaining 20 patients. The success rates were 86% and 70%. Unidentified internal opening and intersphincteric pathology were risk factors for nonhealing. No patients reported fecal incontinence postoperatively. LIMITATIONS: The limitation of this study is its retrospective nature and that all operations were performed by a single surgeon; therefore, the results may vary according to the individual surgeon's expertise. CONCLUSIONS: Fistula tract formation was found in most cases of acute anorectal abscesses. Definitive surgery using this strategy provides promising results.

EXPLORACIN INTERESFINTRICA CON LIGADURA DEL TRAYECTO EN LA FSTULA INTERESFINTRICA O INTENTO DE CIERRE DEL ORIFICIO INTERNO EN ABSCESOS ANORRECTALES AGUDOS: ANTECEDENTES:Los abscesos anorrectales agudos de origen criptoglandular, comúnmente se manejan mediante incisión y drenaje, lo que resulta en el desarrollo de una fístula hasta en un 73% de los casos, requiriendo posteriormente cirugía definitiva de la fístula. Sin embargo, dado que los trayectos de la fístula ya pueden estar inicialmente presentes, puede ser útil el cierre primario del trayecto, como prevención secundaria en la formación de la fístula, mediante la ligadura del trayecto de la fístula interesfintérica.OBJETIVO:El estudio tiene como objetivo, examinar la viabilidad y los resultados en realizar exploración interesfintérica, con ligadura del trayecto de fístula interesfintérica o intento de cierre del orificio interno para abscesos anorrectales agudos.DISEÑO:Se trata de un estudio retrospectivo de pacientes con abscesos criptoglandulares anorrectales agudos, que fueron operados entre enero de 2014 y diciembre de 2016.AJUSTES:Los pacientes fueron tratados en un centro de referencia terciario en Tailandia.PACIENTES:Se incluyeron 86 pacientes con abscesos anorrectales agudos, sin cirugía previa.INTERVENCIONES:Se realizó disección interesfintérica. La intervención quirúrgica adicional dependió de los hallazgos interesfintéricos.PRINCIPALES MEDIDAS DE RESULTADO:La principal medida de resultado, fue la tasa de cicatrización a 90 días.RESULTADOS:De los 86 pacientes, hubo 3 abscesos interesfintéricos bajos, 26 abscesos transesfintéricos bajos, 25 abscesos transesfintéricos anteriores altos, 27 abscesos transesfintéricos posteriores altos y 5 abscesos interesfintéricos altos. La ligadura del tracto de la fístula interesfintérica, con tracto interesfintérico identificable, se realizó con éxito en 66 pacientes. Se realizó exploración interesfintérica, con intento de cierre del orificio interno en los 20 pacientes restantes. Las tasas de éxito fueron 86% y 70% respectivamente. Orificio interno no identificado y patología interesfintérica, fueron factores de riesgo para la falta de cicatrización. Ningún paciente reportó incontinencia fecal posoperatoria.LIMITACIONES:La limitación de este estudio, es su naturaleza retrospectiva y que todas las operaciones fueron realizadas por un solo cirujano, por lo tanto, los resultados pueden variar según la experiencia de cada cirujano.CONCLUSIONES:En la mayoría de los casos de abscesos anorrectales agudos, se encontró formación de trayectos fistulosos. La cirugía definitiva con esta estrategia, proporciona resultados prometedores. Consulte Video Resumen en http://links.lww.com/DCR/B451.

Effectiveness of integrated care on delaying chronic kidney disease progression in rural communities of Thailand (ESCORT-2) trials.

AIM: We conducted a prospective cohort study to evaluate the effectiveness of an integrated care model on delaying chronic kidney disease (CKD) progression in routine clinical practice in rural primary care setting. METHODS: After enrolment, patients with stages 3 to 4 CKD patients from five district hospitals in a northern province of Thailand (400 km from Bangkok) received integrated care comprising hospital multidisciplinary care and home visits by community care teams. Clinical characteristics and biochemical data were collected at baseline and every 3-month interval thereafter for 36 months. The primary outcome was the rate of estimated glomerular filtration rate (eGFR) decline. RESULTS: Nine hundred and fourteen stage -3 and - 4 CKD patients were enrolled. The mean age of our cohort was 62 years. Diabetic kidney disease (DKD) was the main cause of CKD (53%) whereas hypertension was the most common co-morbidity (92%). The mean rate of eGFR decline was -0.92 mL/min/1.73 m2 /year. The rate of eGFR decline among patients with DKD was about three times faster than patients without DKD. Patients with higher blood pressure, metabolic acidosis, proteinuria or anaemia had a faster rate of eGFR decline. CONCLUSION: This integrated care model at the community level was effective in delaying CKD progression in routine clinical practice situation.

Association between self-reported appetite and clinical outcomes of peritoneal dialysis patients: Findings from a low middle-income country.

AIM: Patient-reported outcome measures (PROM) has gained international recognition as important predictors of clinical outcomes in peritoneal dialysis (PD). We sought to understand the associations between patient-reported appetite and clinical outcomes. METHODS: In the Thailand Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS), 690 of 848 randomly selected PD patients from 22 facilities reported their appetite by using the short form (three items) of the Appetite and Diet Assessment Tool (ADAT), between 2016 and 2018. In this questionnaire, the patients rated their appetite as well as a change in appetite over time. Cox proportional hazards model regression was used to estimating associations between self-reported appetite and clinical outcomes, including mortality, haemodialysis (HD) transfer and peritonitis. RESULTS: Half of the PD patients reported a good appetite, whereas 34% and 16% reported fair and poor appetites, respectively. Poor appetite was more prevalent among female, diabetic, congestive heart failure, older age and patients who had worse nutritional indicators, including lower time-averaged serum albumin and serum creatinine concentrations, as well as a higher proportions of hypokalaemia and severe hypoalbuminemia (serum albumin <3 g/dl). After adjusting for age, sex, comorbidities, and PD vintage, poor appetite was associated with increased risks of peritonitis (adjusted hazard ratio [HR] 1.73, 95% confidence interval [CI] 1.14-2.62), HD transfer (adjusted HR 2.25, 95% CI 1.24-4.10) and all-cause mortality (adjusted HR 1.60, 95% CI 1.08-2.39) compared to patients with good appetite. CONCLUSION: Patient-reported poor appetite was independently associated with higher risks of peritonitis, HD transfer and all-cause mortality. This warrants further investigation to identify effective interventions.

Usefulness of an accelerometer-based navigation system in bilateral one-stage total knee arthroplasty.

BACKGROUND: Bilateral one-stage total knee arthroplasty (BTKA) have increased because it provides a number of advantages. Recently, Accelerometer-based navigation (ABN) system which guide the cutting plane without intramedullary disturbance might result in less endothelial and microvascular damage. Therefore, we hypothesized that the ABN may reduce blood loss, reduce postoperative pain, and better restore BTKA alignment compared to conventional instruments. METHODS: We retrospectively compared 44 consecutive patients receiving ABN assisted BTKA (iBTKA) to 57 patients with conventional instruments (cBTKA). Identical pre- and post-operative care was utilized to all patients. The outcome measures assessed were hemoglobin (Hb), calculated blood loss (CBL), blood transfusion, VAS score for pain, morphine consumption, knee flexion angle, and length of stay (LOS). Radiographic assessment included mechanical axis (MA) and component positioning at 3-6 months of follow up. RESULTS: Both iBTKA and cTKA groups had equivalent demographic data. Postoperative Hb of the cBTKA group was significantly lower than those in the iBTKA group at 24 h (p = 0.02), but there was no significant difference in drain volume, CBL, and blood transfusion rate. For radiographic measures, the iBTKA group had more accurate MA and component orientation, and had a lower number of outliers than those in the cBTKA group (p ≤ 0.01), except for the sagittal femoral component angle. CONCLUSION: The ABN assisted BTKA could not reduce blood loss or postoperative pain more than cBTKA, nor improve functional recovery. However, the ABN significantly improved the accuracy of MA and prostheses positioning. TRIAL REGISTRATION: The protocol of this study was registered in the Thai Clinical Trials Registry database No. TCTR20180731001 # on 25 July 2018.

Clinical Characteristics of Patients Hospitalized with Coronavirus Disease, Thailand.

Among 11 patients in Thailand infected with severe acute respiratory syndrome coronavirus 2, we detected viral RNA in upper respiratory specimens a median of 14 days after illness onset and 9 days after fever resolution. We identified viral co-infections and an asymptomatic person with detectable virus RNA in serial tests. We describe implications for surveillance.

The validity and reliability of the PHQ-9 in screening for post-stroke depression.

BACKGROUND: Depression affects about 30% of stroke survivors within 5 years. Timely diagnosis and management of post-stroke depression facilitate motor recovery and improve independence. The original version of the Patient Health Questionnaire-9 (PHQ-9) is recognized as a good screening tool for post-stroke depression. However, no validation studies have been undertaken for the use of the Thai PHQ-9 in screening for depression among Thai stroke patients. METHODS: The objectives were to determine the criterion validity and reliability of the Thai PHQ-9 in screening for post-stroke depression by comparing its results with those of a psychiatric interview as the gold standard. First-ever stroke patients aged ≥45 years with a stroke duration 2 weeks-2 years were administered the Thai PHQ-9. The gold standard was a psychiatric interview leading to a DSM-5 diagnosis of depressive disorder and adjustment disorder with a depressed mood. The summed-scored-based diagnosis of depression with the PHQ-9 was obtained. Validity and reliability analyses, and a receiver operating characteristic curve analysis, were performed. RESULTS: In all, 115 stroke patients with a mean age of 64 years (SD: 10 years) were enrolled. The mean PHQ-9 score was 5.2 (SD: 4.8). Using the DSM-5 criteria, 11 patients (9.6%) were diagnosed with depressive disorder, 12 patients (10.5%) were diagnosed with adjustment disorder with a depressed mood. Both disorders were combined as a group of post-stroke depression. The Thai PHQ-9 had satisfactory internal consistency (Cronbach's alpha: 0.78). The algorithm-based diagnosis of the Thai PHQ-9 had low sensitivity (0.52) but very high specificity (0.94) and positive likelihood ratio (9.6). Used as a summed-scored-based diagnosis, an optimal cut-off score of six revealed a sensitivity of 0.87, specificity of 0.75, positive predictive value of 0.46, negative predictive value of 0.95, and positive likelihood ratio of 3.5. The area under the curve was 0.87 (95% CI: 0.78-0.96). CONCLUSIONS: The Thai PHQ-9 has acceptable psychometric properties for detecting a mixture of major depression and adjustment disorder in post-stroke patients, with a recommended cut-off score of ≥6 for a Thai population.

National feasibility survey of peritoneal dialysis key performance indicators in Thailand from provider perspective.

BACKGROUND: Peritoneal dialysis (PD) has been the main method of renal replacement therapy under the "PD First" policy in Thailand since 2008. Initially, the proposed 13 key performance indicators (KPIs) raised feasibility concerns because of inequitable distribution of resources such as laboratory facilities and/or specialized health-care staff for PD care throughout the country. METHODS: Data availability and goals from the health-care providers' perspective were explored using an online questionnaire survey for all PD centers registered with the Nephrology Society of Thailand from May to June 2016. The availability of essential data required for each KPI indicator to achieve the desired target was assessed using a 5-point Likert scale. RESULTS: Of the 197 centers, 119 responded to the survey (response rate of 60.41%). PD indicators with a high percentage of strongly disagree or disagree were "PD adequacy measured in the last 12 months" (26.83%), "Total weekly Kt/V ≥ 1.7" (24.59%), "3-year PD technique survival" (21.31%), "Serum parathyroid levels within 150 to 500 pg/mL" (16.94%), and a "3-year PD patient survival" (19.01%). As many as 34.17%, 39.19%, 27.27%, 28.93%, and 22.00%, respectively, did not anticipate that the targets could be achieved. Based on the findings from this survey, the national committee concluded that these indicators be removed, and only eight PD indicators were launched. CONCLUSION: Given the importance of KPIs for quality assurance and financial reimbursement, inputs from health-care providers especially data availability and achievement of targets should be considered to ensure feasibility before the final list of indicators are launched.

Husband's willingness-to-pay for HIV and syphilis screening at antenatal care clinic under the Thai universal coverage scheme.

BACKGROUND: Screening for sexually transmitted infection (STI) especially HIV as early detection and treatment have been financially supported under the Thai Universal Coverage (UC) scheme since 2009 (THB140 for HIV). However, the implementation has not been evidence-based, strategic risk-based, nor economically evaluated whereas husbands who accompanied the pregnant women are likely to have a lower risk than those who did not come along. This study is aimed to determine the husband's willingness-to-pay (WTP) for his HIV and syphilis screening tests and potential factors affecting STI screenings at the antenatal care (ANC) clinic of a tertiary hospital in Thailand. METHODS: A pilot open-ended interview was conducted among 50 participants to estimate the mean and standard deviation of WTP prices for HIV and syphilis screening tests. A questionnaire was developed to obtain demographics, STI knowledge and screening history, as well as two contingent valuation methods (bidding and payment scale), using the mean WTP prices identified from the pilot study as a starting WTP with »SD step-up/down. The survey of 200 randomly selected husbands of pregnant women was conducted at King Chulalongkorn Memorial Hospital from April to June 2018. Descriptive statistics and logistic regression were used for data analysis. RESULTS: During the study period, 597 pregnant women received their first ANC. Of 368 accompanying husbands, 200 were enrolled in the study. Their median age was 31 (IQR 27-36) years old and 67% had a first child. Eighty-eight percent of the participants were willing to test for the STIs. Based on the bidding method, WTP prices for HIV and syphilis screening tests were US$14.5 (IQR 12.4-14.5) and US$9.7 (IQR 10-12), respectively. The payment scale method suggested approximately three-quarters of the WTP prices from the bidding method. CONCLUSIONS: The husbands who accompanied their pregnant wives to the ANC clinic showed positive behaviors according to the propitious selection theory. They tend to cooperate well with STI testing and are willing to pay at least two times the price of the STI screening tests. The financial support to promote STI screenings should be reconsidered to cover other groups with higher sexual behavior risks and less WTP.

Timing of periarticular injection has no effect on postoperative pain and functional recovery in simultaneous bilateral total knee arthroplasty: a prospective randomized, double-blinded trial.

BACKGROUND: Given no consensus on optimal timeframe of periarticular multimodal drug injection (PMDI) in knee osteoarthritis patients undergoing total knee arthroplasty (TKA), this study was aimed to compare the postoperative pain and the functional recovery in patients who underwent simultaneous bilateral TKA (SBTKA) and received PMDI at the different intraoperative time points. METHODS: This prospective, randomized, double-blinded controlled trial study included 48 patients who underwent SBTKA and received PMDI mixture, either before prosthetic implantation (late PMDI), or just after knee arthrotomy (early PMDI). Each subject's knees were randomly selected to different PMDI administration time points. The outcome parameters were postoperative pain assessed by using a visual analog scale (VAS), the maximal angle of knee flexion, and quadriceps function from day 1 to 6 weeks after surgery. RESULTS: Late PMDI revealed slightly higher VAS at 6 and 12 h after the operation than early PMDI administration. Afterward, the VAS tended to be lower in the late than early PMDI administration until the end of the study, but without statistical significance. The time difference between early and late PMDI had no effect on postoperative VAS, while older age resulted in significantly less pain. No statistical differences between the two groups in all other outcome parameters were observed. CONCLUSIONS: Postoperative pain reduction and functional recovery of SBTKA with early and late PMDI administration were not significantly different. The time interval of PMDI between knees did not confound the comparison of postoperative pain and functional recovery in SBTKA. TRIAL REGISTRATION: The protocol of this study was retrospectively registered in the Thai Clinical Trials Registry database No. TCTR20170617001 on 16 June 2017.
