Abstract
INTRODUCTION Evidence from previous studies and treatment guidelines suggested that breast-conserving therapy (BCT) is the treatment of choice for early-stage breast cancer. However, in the last decades, surgeons have noticed a high percentage of mastectomies done in this population. The aim of this study is to explore the factors associated with not choosing BCT among eligible patients with early-stage breast cancer. MATERIALS AND METHODS This study uses a retrospective cohort design. Demographic and clinical characteristics derived from The Taiwan Cancer Registry Database, the National Health Insurance Database and the Death File Database from January 1, 2004 to December 31, 2014. Patients were followed until December 31, 2015. To explore the associated factors related to BCT, we used univariate and multivariate logistic regression analysis. RESULTS A total sample of 25,967 stage I breast cancer patients was included. Among them, 12,191 underwent BCT and 13,776 underwent mastectomy as their primary treatment. The logistic regression analysis reveals that age, pay-for-performance (P4P) program participation, number of affected lymph nodes, tumor size and location, were determinants of BCT. Interestingly enough, histological type did not reach the significance level. CONCLUSION This study shows that personal and clinical characteristics influence the treatment choice in stage 1 breast cancer patients.

Abstract
Many patients with cancer report positive changes often referred to as posttraumatic growth (PTG). Some of these self-reported PTG may represent maladaptive illusions created by individuals to cope with the illness. A recently established Posttraumatic Growth and Depreciation Inventory - Expanded version (PTGDI-X) includes both PTG and posttraumatic depreciation (PTD) items. This inventory may provide a more balanced picture of the phenomenological world of cancer survivors. We examined the Chinese version of the PTGDI-X's applicability to cancer patients, and how PTG and PTD were related to posttraumatic stress symptoms. Two hundred sixty-five cancer survivors in Taiwan completed the Chinese version of the PTGDI-X, along with the PTSD Checklist for the DSM-5 to measure posttraumatic stress disorder (PTSD) symptoms. Confirmatory factor analysis showed that the factor structure of the PTGDI-X established in a multi-national study fit our data from cancer patients modestly well. The PTD score had a significant and positive correlation with PTSD symptoms, whereas the PTG and PTSD showed a significant curvilinear relationship in the form of an inverted U-shape. This study's results indicate that PTG and PTD are separated constructs with differential relationships with cancer outcomes. The Chinese version of the PTGDI-X is a viable instrument for psycho-oncological research. The PTD scores can provide useful information to guide cognitive interventions to reduce distorted cognitions. In contrast, the PTG scores can provide further information on the phenomenological world of cancer survivors. In this study, clinical implications and future studies were considered.

Abstract
BACKGROUND AND OBJECTIVES The treatment paradigm for advanced hypopharyngeal cancer has shifted from surgical approaches to organ preservation. However, recent studies indicated that surgical approaches may be associated with better survival rates. This study aimed to conduct a head-to-head comparison of survival outcomes and complications with surgical versus nonsurgical approaches using a nationwide database. METHODS Using a nationwide data set, we gathered 2196 propensity score-matched patients with stage III/IVa hypopharyngeal cancer. We compared survival rates and complications among patients with surgical and nonsurgical cancer treatment. RESULTS Patients with stage III and IVa hypopharyngeal cancer who underwent initial surgery had significantly better 5-year overall survival and disease-free survival rates compared to their nonsurgical counterparts. There were no significant differences in long-term complications with regard to swallowing. CONCLUSIONS These results suggest that patients who underwent initial surgery for advanced hypopharyngeal cancers had better survival rates and equivalent long-term function.

Abstract
OBJECTIVE This study explored the multiple mediating effects of cancer threat appraisal, functional status, and symptom distress on the association between mindfulness and depression in colorectal cancer (CRC) patients at the transition stage after completing cancer treatments. METHODS A total of 90 CRC survivors who received cancer treatments within 3 months participated in this cross-sectional study. The functional status and symptom distress (EORTC-C30 and EORTC CR29), dispositional mindfulness (Five Facet Mindfulness Questionnaire), cancer threat appraisal ( Constructed Meaning Scale), and depressive symptoms (Beck Depression Inventory-II scale) were collected. The mediation and moderation analyses were conducted using the PROCESS macros for SPSS. RESULTS Survivors' dispositional mindfulness (γ = -0.49, p < 0.001) and cancer threat appraisal (γ = -0.59, p < 0.001) were significantly associated with depressive symptoms. Simple mediation analysis indicated that cancer threat appraisal mediated the relationship between dispositional mindfulness and depression (β = -0.02, 95% CI = -0.04 to -0.001). The multiple mediated analysis identified the path between dispositional mindfulness and depression via cancer threat appraisal and colorectal symptom distress (β = -0.01, 95% CI = -0.03 to -0.01). In the mediated moderation model, the path between dispositional mindfulness and depression via colorectal function was moderated by cancer threat appraisal (β = -0.02, 95% CI = -0.05 to -0.004). CONCLUSIONS The two cognitive mechanisms of reducing CRC survivors' depression are as follows: (1) dispositional mindfulness reducing the appraisal of cancer as a threat and increasing positive perceptions of CRC symptoms and (2) the cancer threat appraisal buffered the impacts of CRC's mindfulness and colorectal function on depressive symptoms. Developing mindfulness with cognitive training is recommended for improving depressive symptoms among CRC patients in the transition period.

Abstract
We appraised Warburg effect through analysis of mitochondrial DNA (mtDNA) copy number and maximum standard uptake value (SUVmax) of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) scan and their alterations in esophageal squamous cell carcinoma (ESCC). Later T-status and longer longitudinal tumor length were associated with lower mtDNAESCC copy number (p < .05) but higher SUVmax-ESCC (p < .05), respectively. Lower mtDNAESCC copy number correlated with higher SUVmax-ESCC, reciprocally (p < .05). ESCCs expressing mutant p53 protein had lower mtDNAESCC copy number (p = .056) but higher SUVmax-ESCC (p = .046). We conclude that mutant p53 protein may be involved in the Warburg effect of ESCC.

Abstract
A total of 84 breast cancer survivors completed a package of psychological inventories in 2009 (Time 1), 2012 (Time 2), and 2016 (Time 3). Latent class growth analysis revealed three posttraumatic growth trajectory patterns: distressed posttraumatic growth ( n = 5, 6.7%), illusory posttraumatic growth ( n = 42, 56.0%), and constructive posttraumatic growth ( n = 28, 37.3%). Women with more frequent use of helplessness–hopelessness coping and lower depression levels at Time 1 were more likely to display an illusory than a constructive posttraumatic growth trajectory pattern. Illusory posttraumatic growth might represent a form of coping rather than authentic positive changes. Researchers and clinicians should understand different patterns of posttraumatic growth.

Abstract
Background The effect of single-incision thoracoscopic surgery for lung cancer on long-term survival is unknown and no studies have investigated whether there are differences in survival between single and multiple incision approaches. We aimed to compare long-term overall survival and disease-free survival of patients who underwent single-incision thoracoscopic surgery with those who received multiple-incision thoracoscopic surgery for lung cancer. Methods We retrospectively analyzed 532 patients with lung cancer who underwent either single-incision (n=150) or multiple-incision thoracoscopic resection (n=382) during the period January 2000 to December 2014. Patients were matched on propensity score at a 1:2 ratio to estimate the effect of treatment on long-term and disease-free survival. Overall survival and disease-free survival were assessed using the Kaplan-Meier method, the log-rank test and Cox proportional-hazards regression. Results Propensity matching resulted in 138 patients in the single-incision group and 276 patients in the multiple-incision group. The matched patients in the single-incision group had a significantly better 5-year overall survival than those in the multiple-incision group (P=0.027). Disease-free survival was similar between the two groups before and after matching. The number of chest wall incisions did not influence overall survival or disease-free survival. Conclusions The long-term outcomes of single-incision thoracoscopic surgery are comparable to those of multiple-incision thoracoscopic surgery for lung cancer.

Abstract
Background The objective of this study was to appraise the prognostic role of initial pan-endoscopic tumor length at diagnosis within or between operable esophageal squamous cell carcinoma (ESCC) undergoing upfront esophagectomy or neoadjuvant concurrent chemoradiotherapy (nCCRT) followed by esophagectomy. Methods Between Jan 2001 and Dec 2013 in Koo-Foundation Sun Yat-sen Cancer Center in Taiwan, 101 ESCC patients who underwent upfront esophagectomy (surgery group) and 128 nCCRT followed by esophagectomy (nCCRT-surgery group) were retrospectively collected. Prognostic variables, including initial pan-endoscopic tumor length at diagnosis (sub-grouped ≤3, 3-5 and >5 cm), status of circumferential resection margin (CRM), and pathological T/N/M-status and cancer stage, were appraised within or between surgery and nCCRT-surgery groups. Results Within surgery group, longer initial pan-endoscopic tumor length at diagnosis (≤3, 3-5 and >5 cm; HR =1.000, 1.688 and 4.165; P=0.007) was an independent prognostic factor that correlated with advanced T/N/M-status, late cancer stage, and CRM invasion (all's P<0.001). Based on the initial pan-endoscopic tumor length at diagnosis ≤3, 3-5 and >5 cm, nCCRT-surgery group had a poorer (P=0.039), similar (P=0.447) and better (P<0.001) survivals than did surgery group, respectively. For those with initial pan-endoscopic tumor length at diagnosis >5 cm, nCCRT-surgery group had more percentage of T0/N0-status and stage 0 (all's P<0.05), and fewer rate of CRM invasion (P=0.036) than did surgery group. Conclusions Initial pan-endoscopic tumor length at diagnosis could be a criterion to select proper ESCC cases for nCCRT followed by esophagectomy to improve survival and reduce CRM invasion.

Abstract
Background We report the feasibility and safety of chest surgery through the subxiphoid single port approach based on our preliminary experience. Methods From December 2013 till January 2016, 39 patients underwent 40 thoracoscopic surgeries via a 3- to 4-cm subxiphoid single incision. A sternal lifter was applied for better entrance and working angle. A zero-degree deflectable scope was preferred. The technique for anatomic resection was similar to that in the traditional single-port approach. Patient characteristics and demographic data were analyzed. Results There were 29 females and 10 males, with a median age of 56 years. Indication for surgery included 24 patients with primary lung cancer, eight with lung metastases, two with benign lung lesions, one with bilateral pneumothorax, and five with mediastinal tumors. Surgeries included lobectomy in 21, segmentectomy in five, wedge resection in nine, and mediastinal surgery in five patients. There was no surgical mortality. Complications (10%, 4 in 40) included postoperative bleeding in one patient, chylothorax in one patient, and transient arrhythmia in the early learning curve in two patients. Conclusions Our results indicated that subxiphoid single-incision thoracoscopic pulmonary resection could be performed safely but under careful patient selection with modification of instruments. Moreover, having a previous single-port incision experience was crucial. Major limitations of this approach included more frequently encountered instrument fighting; interference of left-side procedure related to heartbeat and radical mediastinal lymph node (LN) dissection; and the ability to handle complex conditions, such as anthracotic LNs, diffuse adhesion, and major bleeding.

BACKGROUND Single-port video-assisted thoracoscopic surgery (VATS) has attracted much attention recently; however, it is still very challenging to perform especially on more technically demanding sublobar anatomic resection procedures such as segmentectomy. Therefore we conducted a retrospective study on the perioperative results of single-port segmentectomy using a propensity-matched method for comparison with multi-port segmentectomy in patients with primary lung cancer. METHODS For procedures of anatomic segmentectomy performed between May 2006 and March 2014, we retrieved data on patients' demographic information, medical history, cancer information, and postoperative outcomes from our surgical database of thoracoscopic lung cancer surgery. Outcome variables included the number of lymph nodes retrieved during the surgery, the amount of blood loss, the duration of hospitalization, the length of the wound, the operation duration in minutes, and incidence and types of complication. The t-test and Chi-squared test were used to compare demographic and clinical variables between single- and multi-port approaches. RESULTS A total of 98 consecutive patients who underwent VATS segmentectomy for lung cancer treatment were identified in our database: 52 (53.1%) underwent a single-port segmentectomy and 46 (46.9%) had a multi-port segmentectomy. After propensity score matching, the differences in patients' age, pulmonary function tests, tumor size, and operating surgeons were no longer significant between the two sample groups. The length of the wound was the only surgical outcome for which single-port segmentectomy had a significantly better outcome than multi-port segmentectomy (P value <0.001). CONCLUSIONS This study showed that single-port VATS segmentectomy yielded comparable surgical outcomes to multi-port segmentectomy despite technique difficulties and smaller wound in our setting.

Abstract
BACKGROUND Subtotal esophagectomy with radical lymph node dissection (RLND) remains an effective therapeutic strategy for localized esophageal squamous cell carcinoma (ESCC). However, controversy exists regarding the extent to which RLND should be performed. We reappraised the prognostic impact and accurate nodal staging of RLND in ESCC. METHODS The data from 101 ESCC patients (mean age, 57.5 years; 93 men) who underwent primary subtotal esophagectomy were retrospectively collected. Candidate variables, including the number of total dissected lymph nodes (TDLN [subgrouped into TDLN less than 13, TDLN 13 to 40, and TDLN more than 40]), were evaluated to determine their prognostic impacts and hazard ratio (HR). RESULTS Fewer TDLN (p < 0.001; HR 9.011, 2.449, and 1.000 for TDLN less than 13, TDLN 13 to 40, and TDLN more than 40, respectively), tumor length exceeding 3.5 cm (p < 0.001; HR 3.321), resection margin invasion (p < 0.001; HR 14.493), and positive nodal status (p = 0.002; HR 2.730) were independent predictors of a poor prognosis. Considering the 54 node-negative patients, more TDLN correlated with improved survival (p = 0.001). Risk analysis demonstrated that one fewer TDLN could contribute to an increased HR of 1.047 (p = 0.014). However, RLND involving more TDLN appeared to lose the prognostic impact for the 47 node-positive patients (p = 0.072). Furthermore, the number of positive dissected lymph nodes remained at approximately 4 if the number of TDLN exceeded 20. CONCLUSIONS For N-negative or N-positive ESCC patients undergoing primary surgical resection, the number of TDLN influenced their prognosis or nodal staging accuracy, respectively. At least 20 TDLN were necessary for N-positive patients.

Abstract
PURPOSE Case-control studies have reported inconsistent findings regarding the association between mobile phone use and tumor risk. We investigated these associations using a meta-analysis. METHODS We searched MEDLINE (PubMed), EMBASE, and the Cochrane Library in August 2008. Two evaluators independently reviewed and selected articles based on predetermined selection criteria. RESULTS Of 465 articles meeting our initial criteria, 23 case-control studies, which involved 37,916 participants (12,344 patient cases and 25,572 controls), were included in the final analyses. Compared with never or rarely having used a mobile phone, the odds ratio for overall use was 0.98 for malignant and benign tumors (95% CI, 0.89 to 1.07) in a random-effects meta-analysis of all 23 studies. However, a significant positive association (harmful effect) was observed in a random-effects meta-analysis of eight studies using blinding, whereas a significant negative association (protective effect) was observed in a fixed-effects meta-analysis of 15 studies not using blinding. Mobile phone use of 10 years or longer was associated with a risk of tumors in 13 studies reporting this association (odds ratio = 1.18; 95% CI, 1.04 to 1.34). Further, these findings were also observed in the subgroup analyses by methodologic quality of study. Blinding and methodologic quality of study were strongly associated with the research group. CONCLUSION The current study found that there is possible evidence linking mobile phone use to an increased risk of tumors from a meta-analysis of low-biased case-control studies. Prospective cohort studies providing a higher level of evidence are needed.

Abstract
Objective This study explored the prevalence of panic disorder and other psychiatric disorders in young Han Chinese males with mitral valve prolapse (MVP). With the factors of age, sex, and ethnicity controlled, the specific role of MVP in panic disorder was analyzed. Methods Subjects with chest pain aged between 18 and 25 years were assessed with the echocardiograph for MVP and the Chinese version of the Mini-International Neuropsychiatric Interview for panic disorder (n = 39). Results Of the 39 participants, 35.9% met the diagnosis of anxiety disorder, 46.2% met at least one criterion of anxiety disorder, and 23.1% met the diagnostic criteria of major depressive disorder. There was no statistically significant difference in the prevalence of panic disorder between one of the (8.3%) MVP patients, and two (7.4%) control participants. Conclusions There is a high prevalence of psychiatric disorder, including anxiety disorder and major depressive disorder, in those who report pain symptoms, so that diagnosis and treatment of these patients is of great importance. In addition, individuals with MVP did not have an increased risk for panic disorder. Whether MVP may be a modifier or mediating factor for panic disorder needs to be further assessed in a larger scale study.

Abstract
CD14, a pattern recognition receptor on monocyte and macrophage, plays a central role in innate immunity through recognition of bacterial lipopolysaccharide and initiation of inflammatory response. Recently, CD14/-260C>T promoter gene polymorphism has been found to be related to a risk of inflammatory diseases. Our results showed that the C allele frequency among Chinese in Taiwan was lower than those in Western countries. The membrane CD14 expression was significantly higher in TT as compared with CT and CC genotypes (P=0.034, 0.044, respectively). There was a higher level of soluble CD14 in TT and CT genotypes than in CC genotypes. In addition, TNFalpha production in whole blood was significantly higher in TT genotype than in CC genotype after stimulation by Chlamydiae. In conclusion, the single base pair polymorphism of CD14 promoter gene is associated with CD14 expression and Chlamydia-stimulated TNFalpha production, and may thus play some role in the chlamydia-induced inflammatory response.

Abstract
Two novel cyclic tetrapeptides: cyclo[Lys-Tyr-Lys-Ahx-] 7a and cyclo[Lys-Trp-Lys-Ahx-] 7b were synthesized by coupling protected amino acid in solution and the subsequent cyclization effected by the pentafluorophenyl ester method as described in previous papers. These cyclic peptides were designed and synthesized to study their interaction with DNA, based on previous reports that linear peptides Lys-Tyr-Lys and Lys-Trp-Lys could bind to various forms of DNA and cleaved supercoiled DNA at apurinic sites. Ethidium bromide displacement assay showed that the apparent DNA binding constant of linear Lys-Tyr-Lys and cyclic peptide 7a are far below 1 x 10(3) M(-1), whereas those of cyclic peptide 7b and linear Lys-Trp-Lys are 1.9 x 10(4) M(-1) and 9.5 x 10(3) M(-1), respectively. Kinetic studies using agarose gel electrophoresis showed that cyclic peptide 7b and Lys-Trp-Lys possessed DNA nicking activity on natural supercoiled phi X174 DNA with nicking rate of 50.7 and 75.6 pM min(-1) at 65 degrees C, respectively, whereas cyclic peptide 7a and linear Lys-Tyr-Lys were devoid of the corresponding activity. The DNA nicking rate increased significantly with increase in reaction temperature. At reaction temperatures lower than 65 degrees C, the DNA nicking rate of cyclic peptide 7b exceeded that of linear Lys-Trp-Lys. The addition of 1 microM ferrous ion did not give significant enhancement effect on the DNA nicking rate by the peptides. UV irradiation gave a marked rate enhancement on the DNA nicking rate of linear Lys-Trp-Lys and a moderate enhancement on the DNA nicking rate of cyclic peptide 7b.

Abstract
Residual limb recovery after a transtibial amputation depends largely on close monitoring of the weight-bearing activities during the early postoperative stage. Although a biofeedback device, in particular audio biofeedback, was recommended to be used, no quantitative studies regarding its effectiveness in monitoring the weight-bearing activity of a person with amputation were available. In this study, six persons with transtibial amputation were asked to replicate a prescribed amount of weight bearing using a bathroom scale method during their early postoperative ambulatory training. Their weight-bearing characteristics with and without using audio biofeedback were continuously monitored using a load monitoring device and compared with the prescribed load. The results showed that the residual limb would be overloaded using the conventional bathroom scale method during early postoperative ambulatory training if no audio biofeedback was provided. It was demonstrated that audio biofeedback was useful in preventing the residual limb from being overloaded beyond the prescribed load particularly when the prescribed load was low.

Abstract
In October 1988, a series of food poisoning cases occurred in the State of Perak in Malaysia. Most of the victims were children. Ultimately 13 children between the ages of 2.5 and 11 years died. Epidemiological investigations showed that the probable source of the poison was Loh See Fun, a noodles in the shape of a rat's tail. All the deceased ate the noodles from one supplier. Clinical and pathological findings were similar in each case. Postmortem examination was performed in 11 cases. Toxicological examination on organs in 10 cases showed a high concentration of aflatoxin in tissues of the deceased. High levels of boric acid were excreted from most of the victims. Histological examination of the liver in these cases showed necrotic changes found in aflatoxin poisoning. Combination of the epidemiological, clinical, toxicological, and pathological findings pointed to the fact that there was a common toxin or toxins responsible for the deaths. These were thought to be a combination of boric acid and aflatoxin.

Abstract
Sodium resin has been clinically administered against hyperkalemia widely, but its effects of lowering the serum calcium has never been documented. In our study, 7 patients with chronic renal failure were chosen at random to take sodium resin 30 g per day for 3 days. The sodium resin not only lowered the serum potassium level (p less than 0.05) but also brought down the level of serum calcium (p less than 0.05). The reduced ability of patients with chronic renal failure to absorb calcium from the gastrointestinal tract is well recognized, so its effects of lowering calcium will be more likely to aggravate the serum calcium imbalance further. If sodium resin has to be used for the maintainance of serum potassium in patients with chronic renal failure the serum calcium should be monitored closely in order to lighten the osteodystrophy and secondary hyperparathyroidism.

Abstract
The photographic superimposition technique requires an antemortem photograph to be enlarged to life size and the skull to be photographed from the same angle as the antemortem photograph. This paper describes how the magnification factor can be extrapolated by measuring the true interpupil distance of a second person and the photographic interpupil distance of the suspect and the second party. A closed-circuit television (CCTV) system is used to determine quickly the skull photographic angle. We believe these techniques are viable and easy to perform.

Abstract
Serum C1q concentrations were studied in 78 patients with definite and classical rheumatoid arthritis (RA). No correlation could be made either with disease activity, with erythrocyte sedimentation rate or with rheumatoid factor titers. In contrast to these findings in RA, however, serial determinations of this complement component were of value in predicting the response to therapy in four patients with immunologically-mediated vasculitis. Initially both C1q and C3 were depressed in two patients with SLE, one with cryoglobulinemic purpura and one with HbsAg-positive serum sickness, each with acute vasculitis. Sequential studies following the institution of treatment showed in each case that C1q returned to normal while C3 remained low. These observations suggest that analysis of serum C1q is preferable to C3 in these disorders when used to predict clinical change and the response to treatment.
