RATIONALE: The liver is the most common site of metastasis from colorectal cancer. Curative intent liver metastasectomy has shown improvement in overall survival. This manuscript will present the long-term oncologic outcomes of hepatic metastasectomy for colorectal cancer with resectable liver metastasis. METHODS: Data of patients with resectable liver metastases from colorectal cancer who underwent hepatic resection at the Philippine General Hospital over a 10-year period was reviewed. The primary outcome investigated was overall survival. RESULTS: Thirty patients were included in the study. The median overall survival was 20 months, with a 2-year and 5-year overall survival rate of 40% and 6.67% respectively. Eleven (36.67%) patients had disease recurrence, with a median disease-free survival of 16 months. A significant difference in survival was seen between patients with synchronous and metachronous liver metastasis (20.38 and 36.78 months respectively, p=0.0393) and in patients given adjuvant chemotherapy at any time in relation to the occurrence of the liver metastases versus patients who did not receive any adjuvant treatment (34.08 and 18.59 months respectively, p=0.0349). Trends towards improved overall survival were seen in patients 50 years old or less (36.86 versus 21.78 months, p=0.0837) and in patients with a clinical risk score of 2 or less (29.65 versus 19.62 months, p=0.1823), which may show significance in a higher powered study CONCLUSION Improved overall survival was observed among patients with colorectal liver metastases undergoing hepatic metastasectomy compared to no liver resection.

BACKGROUND/AIMS: Gastroesophageal reflux disease is a highly prevalent disease. Assessing treatment efficacy is critical in that clinical endpoints are properly evaluated. Clinical tools for symptoms severity assessment should be discriminative, predictive and evaluative. METHODS: In this study we compared a patient-oriented symptoms evaluation (ReQuest(TM)) vs a structured interview assessment initiated by a physician (sickness impact profile [SIP]). Both questionnaires were analyzed in a multidimensional space using latent factors. Five dimensions were found: 1 for the short ReQuest(TM) questionnaire and 4 for SIP. RESULTS: We included 1,522 women and 1,296 men; mean age was 36 +/- 7 years, and mean body mass index was 26 +/- 4. The score questionnaire assessment evaluation by physicians and patients did not correlate between them (between r = 0.03 and 0.26) except nausea and sleep disorder (r = 0.45 and 0.51) but both were sensitive enough to detect changes after treatment (P < 0.05). Medical specialty of the physician showed effect on the score of both, ReQuest(TM) and SIP evaluation. Questionnaire variance decomposition due to specialist was only 2% (P < 0.05). CONCLUSIONS: While both evaluations are orthogonal (non-correlated), meaning patients and physicians measured diverse aspects of the same disease, they both were able to measure patient's improvement with treatment.

Background: The result of illicit polymer injection is chronic inflammation with foreign-body granuloma (FBG) formation. Treatment can be divided into medical and surgical. Some patients develop severe complications with need surgical treatment. This study aims to describe patients who underwent surgical removal of the FBGs and autoimmune/inflammatory syndrome induced by adjuvants (ASIA); additionally, we evaluated the quality of life after surgery. Methods: In this retrospective single-center study, the authors examined data of patients who underwent surgical removal of FBG caused by illicit polymer injection for cosmetic purposes and confirmed ASIA from 2015 to 2020 by three different surgical approaches. Descriptive summary statistics were reported on patient demographics, presenting symptoms and clinical examination features, treatment strategies, histopathology reports and quality of life. Results: The cohort included 11 female patients with FBGs and ASIA. The most affected anatomical zones were the combination of gluteal region, thighs and legs (40%); and thighs with legs (20%). Main presentation was: skin hyperpigmentation (90.9%), skin induration (63.6%), chronic fatigue (63.6%), and ulcers (36.4%). Surgical modalities consisted of: ultrasonic-assisted liposuction in four patients (36.4%); open en bloc excision and primary closure in four patients (36.4%); and open en bloc excision and microsurgical reconstruction in three patients (27.2%). The postoperative quality of life visual analog scale score was 83.9. Conclusions ASIA treatment represents a challenge for the plastic surgeon. Adequate surgical treatment emphasizing, when possible, the total or near-total resection of the FBG must be performed to improve ASIA evolution.

OBJECTIVES: Due to the uncontrolled increase of the mobile health applications and their scarce use by elderly for reason of absence credibility of measurements by lack scientific support, the aim of this study was to evaluate the differences between the biophysical measurements based on standard instrument against a mobile application using controlled experiments with elderly to propose an effective validation model of the developed apps. METHODS: The subjects of the study (50 people) were elderly people who wanted to check their weight and cardiac status. For this purpose, two mobile applications were used to measure energy expenditure based on physical activity (Activ) and heart rate (SMCa) during controlled walking at specific speeds. Minute-by-minute measurements were recorded to evaluate the average error and the accuracy of the data acquired through confidence intervals by means of statistical analysis of the data. RESULTS: The experimental results obtained by the Activ/SMCa apps showed a consistent statistical similarity with those obtained by specialized equipment with confidence intervals of 95%. All the subjects were advised and trained on the use of the applications, and the initial registration of data to characterize them served to significantly affect the perceived ease of use. CONCLUSIONS: This is the first model to validate a health-app with elderly people allowed to demonstrate the anthropometric and body movement differences of subjects with equal body mass index (BMI) but younger. Future studies should consider not only BMI data but also other variables, such as age and usability perception factors.

Objective: To measure the ciliary sulcus diameters (CSD) in phakic eyes of adult Filipinos using ultrasound biomicroscopy (UBM). Methods: This was an observational, cross-sectional study involving Filipino patients recruited from the Outpatient Department of Makati Medical Center, Philippines from September 2006 to December 2006. Vertical and horizontal CSDs in phakic eyes were measured using a UBM Scan 1000 (Ophthalmic Technologies Inc., Toronto, Ontario, Canada). Three repeated measurements of each meridian were taken and averaged. The average CSD for each eye was computed as the average of the horizontal and vertical CSDs. Student’s t-test was used to analyze data. Results: Seventy-one (71) patients (142 eyes) were included in the study. Mean CSD measurements were as follows: horizontal CSD = 9.76 ± 0.42 mm; vertical CSD = 10.00 ± 0.48 mm; average CSD = 9.88 ± 0.47 mm. There was a significant difference between the means of the vertical and horizontal CSD measurements (P<0.01). There was no significant difference in the mean CSD measurements of the right and left eyes (P= 0.50). Conclusions In this cohort of adult Filipino patients, the UBM-measured vertical CSD is significantly greater than the horizontal CSD. Establishment of CSD measurements of adult Filipino eyes may be helpful in selecting appropriately-sized intraocular lenses for ciliary sulcus implantation.

The distribution of red-spotted grouper nervous necrosis virus (RGNNV) antigens was examined by immunohistochemistry in the nervous and non-nervous organs of juvenile European seabass (Dicentrarchus labrax) during the course of an intramuscular infection. Histological changes resulting from the infection were evaluated from 3 days to 2 months post-infection. The specific antibody response was also studied 2 months post-challenge. Viral proteins were present throughout the experimental period in the retina (inner nuclear layer, ganglion layer, outer limiting membrane, and outer plexiform layer), brain (cerebellum and tectum opticum), and liver (hepatocytes and endothelial cells). These proteins were also observed in the renal tubular cells, white pulp of spleen, and in fibroblasts and cartilage of caudal fin. This is the first report of RGNNV proteins appearing in these organs, where the immunostaining was only detected at certain sampling times after the onset of mortality. Brain and retina of virus-exposed fish showed high levels of vacuolation, while accumulation of fat vacuoles was observed in the liver. RGNNV infection also induced a specific antibody response as measured by an ELISA. In summary, this is the first study demonstrating the presence of viral proteins in cells of caudal fin, kidney and spleen of European seabass.

BACKGROUND: Autoimmune hemolytic anemia (AIHA) is characterized by an autoimmune-mediated destruction of red blood cells. Warm AIHA (wAIHA) represents 60% of AIHA cases and is associated with the positive detection of IgG and C3d in the direct antiglobulin test (DAT). This study aimed to assess the clinical and laboratorial differences between primary and secondary wAIHA patients from a referral center in Mexico City. METHODS: All patients diagnosed with wAIHA in our institution from January 1992 to December 2015 were included and received corticosteroids as the first-line treatment. We analyzed the response to the first-line treatment, relapse-free survival, and time to splenectomy. RESULTS: Eighty-nine patients were included. Secondary wAIHA represented 55.1% of the cases. At diagnosis, secondary wAIHA patients showed a DAT mixed pattern more frequently than primary wAIHA patients (36.7 vs. 17.5%, P<0.001). In the survival analysis, patients with secondary wAIHA had a lower time to response (18 vs. 37 days, P=0.05), median disease-free survival (28.51 vs. 50.95 weeks, P=0.018), and time to splenectomy (43.5 vs. 61 wks, P=0.029) than those with primary wAIHA. Due to economic constraints, rituximab was considered as the third-line treatment in only two patients. CONCLUSION: Secondary wAIHA may benefit from a longer low-dose steroid maintenance period mainly due to its shorter time to relapse and time to splenectomy than primary wAIHA.
