An objective assessment of the impact of tendon retraction on sleep efficiency in patients with full-thickness rotator cuff tears: a prospective cohort study

Sleep quality, quantity, and efficiency have all been demonstrated to be adversely affected by rotator cuff pathology. Previous measures of assessing the impact of rotator cuff pathology on sleep have been largely subjective in nature. This study was undertaken to objectively analyze this relationship through the use of activity monitors. Methods: Patients with full-thickness rotator cuff tears at a single institution were prospectively enrolled between 2018 and 2020. Waistworn accelerometers were provided for the patients to use each night for 14 days. Sleep efficiency was calculated using the ratio of the time spent sleeping to the total amount of time that was spent in bed. Retraction of the rotator cuff tear was classified using the Patte staging system. Results: This study included 36 patients: 18 with Patte stage 1 disease, 14 with Patte stage 2 disease, and 4 patients with Patte stage 3 disease. During the study, 25 participants wore the monitor on multiple nights, and ultimately their data was used for the analysis. No difference in the median sleep efficiency was appreciated amongst these groups (P>0.1), with each cohort of patients demonstrating a generally high sleep efficiency. Conclusions: The severity of retraction of the rotator cuff tear did not appear to correlate with changes in sleep efficiency for patients (P>0.1). These findings can better inform providers on how to counsel their patients who present with complaints of poor sleep in the setting of full-thickness rotator cuff tears. Level of evidence: Level II.

Predictors and outcomes of hospitalized COVID-19 patients with liver injury

Objective@#To determine incidence, predictors, and impact of liver injury among hospitalized COVID-19 patients@*Methods@#This is a retrospective cohort study of hospitalized COVID-19 patients at the University of the PhilippinesPhilippine General Hospital. Liver injury (LI) was defined as ALT elevation above institutional cut-off (>50 u/L) and was classified as mild (>1x to 3x ULN), moderate (>3x to 5x ULN), or severe (>5x ULN). Significant liver injury (SLI) was defined as moderate to severe LI. Univariate analysis of SLI predictors was performed. The impact of LI on clinical outcomes was determined and adjusted for known predictors -age, sex, and comorbidities.@*Results@#Of the 1,131 patients, 565 (50.04%) developed LI. SLI was associated with male sex, alcohol use, chronic liver disease, increasing COVID-19 severity, high bilirubin, AST, LDH, CRP, and low lymphocyte count and albumin. An increasing degree of LI correlated with ICU admission. Only severe LI was associated with the risk of invasive ventilation (OR: 3.54, p=0.01) and mortality (OR: 2.76, p=0.01). Severe LI, male sex, cardiovascular disease, and malignancy were associated with longer hospital stay among survivors.@*Conclusion@#The liver injury occurred commonly among COVID-19 patients and was associated with important clinicodemographic characteristics. Severe liver injury increases the risk of adverse outcomes among hospitalized patients.

The hematologic profile of Filipino HIV-infected individuals and its association with CD4 counts

ABSTRACT Introduction: Hematologic abnormalities are common in HIV and involve all blood cell lineages. A study on cytopenias, as correlated with disease progression, can be valuable in resource-limited settings. This study aimed to determine the hematologic profile of HIV patients and its association with CD4 count and antiretroviral (ARV) treatment. Methods: This is a retrospective cohort study involving adult Filipino HIV patients with complete blood count (CBC) and CD4 count determinations prior to the initiation of ARV treatment and after ≥6 months of ARV treatment. Logistic regression was performed to determine the association between cytopenias and a CD4 count <200 cells/μL. Results: The study included 302 patients. Anemia was the most common cytopenia. Anemia and leukopenia were associated with an increased likelihood of having a CD4 count <200 cells/μL in ARV-naïve patients. In ARV-treated patients, leukopenia was associated with an increased probability of having a CD4 count <200 cells/μL. An increase in hemoglobin, white blood cell (WBC) and platelet counts was observed after ≥6 months of ARV treatment. Conclusion: Anemia and leukopenia can be used as markers of immune status in HIV-infected individuals and improvement in the CBC parameters can be used to assess response to ARV treatment. Routine monitoring of hematologic parameters is recommended.

A prospective cohort study of the Quick Sequential Organ Failure Assessment (qSOFA) score versus Systemic Inflammatory Response Syndrome (SIRS) criteria in the determination and prognostication of sepsis in a Philippine Tertiary Hospital

@#<p style="text-align: justify;"><strong>Background:</strong> Sepsis is a leading cause of mortality both locally and worldwide. Despite this, early diagnosis of sepsis remains challenging, with a significant number not fulfilling SIRS (Systemic Inflammatory Response Syndrome) criteria. In 2016, the Sepsis-3 guidelines modified its definition to include the qSOFA (Quick Sequential Organ Failure Assessment) score in an attempt to include a significant number of SIRS-negative septic patients.</p><p style="text-align: justify;"><strong>Methods:</strong> To compare the two, 295 adult patients in the emergency room with suspected infection were included in the study and simultaneously determined their qSOFA score and SIRS criteria. Three infection specialists adjudicated the presence of sepsis, and outcomes within the first 48 hours were acquired. Sensitivity, specificity, positive predictive and negative predictive values for qSOFA and SIRS were computed using constructed confusion matrices, and overall predictive accuracy was measured by the Area under the Receiver Operating Characteristic (AUROC) curve.</p><p style="text-align: justify;"><strong>Results:</strong> Of the 295 patients included in the study, 95 (32.2%) were deemed sepsis positive via adjudication. The qSOFA score was a specific (95.5%) but a poorly sensitive (46.3%) test compared to the SIRS criteria (sensitivity 73.7% and specificity 60%). Both qSOFA and the SIRS criteria significantly correlated with sepsis positivity, but the qSOFA score had superior overall predictive accuracy at 70.9% compared to the SIRS criteria. The adjudicators had moderate strength in agreement (Fleiss' kappa = 0.39) and a percentage agreement of 60%.</p><p style="text-align: justify;"><strong>Conclusion:</strong> We concluded that the qSOFA score was a more accurate predictor of sepsis and a reliable pre-dictor of in-hospital mortality, but should not be used as a sepsis screening tool due to the low sensitivity. We recommend that the SIRS criteria be maintained as a screening tool and to use the qSOFA score concurrently for time management.</p><p style="text-align: justify;"><strong>Key Words:</strong> Sepsis, qSOFA, SIRS</p>

Characteristics and factors associated with mortality of 200 COVID-19 patients at a Philippine COVID-19 tertiary referral center

@# Objectives: To describe the clinical profile and factors associated with mortality among the first 200 patients confirmed to have COVID-19 infection admitted in the University of the Philippines – Philippine General Hospital (UP-PGH) Methodology: We conducted a retrospective review of adult patients with confirmed COVID-19 infection admitted in PGH, a designated COVID-19 referral center. Demographic, clinical data, and clinical outcomes were extracted from medical records. Frequencies and distributions of various clinical characteristics were described, and factors associated with mortality were investigated. Results: Of the 200 patients in our cohort, majority were male (55.5%), and more than half (58%) were over 60 years old. Underlying co-morbid illnesses (67.5%) included hypertension (49.5%), diabetes mellitus (26.5%), and cardiovascular disease (20.5%). Most frequent presenting symptoms were cough (69.0%), fever (58.5%), or shortness of breath (53.0%). Most patients presented with mild (n=41, 20.5%) to moderate illness (n=99, 49.5%) and only 60 were considered severely (n=32, 16.0%) or critically ill (n=28, 14.0%). Many (61%) received empiric antibiotics, while 44.5% received either repurposed drugs or investigational therapies for COVID-19. Bacterial co-infection was documented in 11%, with Klebsiella pneumoniae commonly isolated. In-hospital mortality was 17.5%, which was highest for critical COVID-19 (71.4%). Mortality was observed to be higher among patients age 60 and above, those requiring oxygen, ventilatory support and ICU admission, and among those who developed acute kidney injury, acute stroke, sepsis, and nosocomial pneumonia. Conclusion: Our study confirms that COVID-19 affects males, older individuals and those with underlying co-morbid conditions. Empiric antimicrobial treatment was given for majority of patients, despite documentation of bacterial infection in only 11%. K. pneumoniae was commonly isolated, reflecting local epidemiology. Mortality rate during this early period of the pandemic was high and comparable to other institutions. Factors associated with mortality were related to critical COVID-19 and are similar to other studies.

Oral versus Intravenous Antibiotic treatment for Osteomyelitis in Adults: A Systematic Review and Meta-Analysis

@#BACKGROUND: The worldwide incidence of osteomyelitis is approximately 21.8 cases per 100,000 person-years. The cornerstone of treatment is prolonged (4-6 weeks) intravenous antibiotic administration. This entails additional cost, inconvenience, and added manpower from the healthcare system. Thus, studies have explored the possible use of oral antibiotics as alternatives to improve patient compliance and reduce costs. Our meta-analysis aimed to compare the efficacy of oral versus intravenous antibiotics in treating adult patients with osteomyelitis. MATERIALS AND METHODS: Electronic databases (PubMed, Medline, EMBASE, Cochrane Central Register of Controlled Trials, Google Scholar, and Research Gate) from 1966 to April 2020 were searched using the terms “oral antibiotics”, “osteomyelitis”, “randomized controlled trial”. Only studies that directly compared oral versus intravenous antibiotics and confirmed osteomyelitis through biopsy and/or imaging were included. Primary outcome is remission (resolution of symptoms with no relapse and bacteriologic eradication); secondary outcomes, (a) relapse (persistence of the pathogen after treatment) and (b) adverse events. The validity of included studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions. We performed a random-effects model in Review Manager Version 5.3 with 95% confidence interval. The I 2 test was used to assess heterogeneity. RESULTS: Seven of 89 trials comprised of 1,282 patients were included in the final analysis. All studies included patients with osteomyelitis of the lower extremities. Oral antibiotics used were Ciprofloxacin, Ofloxacin, and Co-trimoxazole; intravenous antibiotics used were deemed appropriate by the infectious disease specialist. Patients were only given either oral or intravenous antibiotics. Results showed an 8% increase in remission rates [RR 1.08 (0.81 to 1.44, 95% CI, Z = 0.52, p=0.60)] with no heterogeneity (I2 = 0%) in the intravenous antibiotics group. However, this was not statistically significant. Furthermore, there was a 62% decrease in relapse rates in the intravenous antibiotics group [RR 1.62 (0.85 to 3.07, 95% CI, Z = 1.47, p = 0.14)] with no heterogeneity (I2 = 0%) but was not statistically significant. CONCLUSION: Oral are comparable to intravenous antibiotics in treating osteomyelitis in terms of remission and relapse rates. However, larger and double-blinded trials should be done to generate more robust data to validate these claims.

Influence of different orientations and rates of bidirectional distraction osteogenesis of the mandibular corpus: a three-dimensional study

Objective: The objective of this study was to evaluate the biomechanical effect of mandibular corpus distraction osteogenesis with different orientations and rates. Materials and Methods: A three-dimensional model of the mandible was created. The vertical surgical cut was made, the force was applied horizontally in a bidirectional manner within two orientations: parallel to the occlusal plane and parallel to the inferior border of the mandible with three rates (0.5mm, 1mm and 1.5mm). Results: The maximum values for von Mises stress when the force was applied parallel to the inferior border of the mandible with all three rates were smaller than those with force direction parallel to the occlusal plane. The displacement in all three directions x, y, and z were not parallel and prominent in the anterior part of the mandible, while the movement at the posterior part is negligible, x and z displacement were bigger when force was applied parallel to the inferior border of the mandible, z displacement was more prominent than x and y displacement, both directions produced upward rotation of the mandible, this rotation was more noticeable when the force was applied parallel to the inferior border of the mandible. Conclusions: A vertical cut can be used in the patient with a long anterior face. This site of distraction achieves more lengthening of mandible than expansion.

A post marketing surveillance study on the efficacy and safety of bosentan for treatment of pulmonary arterial hypertension among adult Filipino patients

BACKGROUND@#Pulmonary arterial hypertension (PAH) is a chronic, debilitating disease affecting millions of adults worldwide. With improved knowledge on PAH and better management, long-term survival in patients has significantly increased in the past 20 years. Bosentan is a nonselective, dual endothelin receptor antagonist used in the treatment of PAH. While the drug has already been established to improve exercise capacity and patient survival globally, no study has investigated its clinical effectiveness and safety among Filipino patients yet. A post marketing study was conducted to determine the efficacy and safety of bosentan (125 mg administered twice daily) among adult Filipino patients with PAH.@*METHODS@#A non-randomized, non-comparative, open-label trial was conducted involving adult patients at a tertiary government hospital in Metro Manila. Study duration was from March to September 2012. Primary end points of the study were patients' response to efficacy and safety.@*RESULTS@#A total of 14 patients were enrolled in the study and 13 included in the analysis. Mean age of the participants was 34 ± 11.54 years. Remarkable changes were observed for 6WMD and small improvements noted for Borg dyspnea index and CPET. There was no difference between baseline and 12th week WHO functional classification. FEVl /FVC, MVV, RV /TLC and sRaw showed modest improvement; there was a notable difference in the systolic PAP vs baseline; PVR, PVRI, SVR and SVRI demonstrated the largest changes via cardiac catherization and iloprost. Four patients experienced at least one serious adverse event, with one reported as suspected unexpected serious adverse reaction. Out of 13 patients, 1 O (76.9%) considered bosentan as effective while 11 (84.6%) considered it safe.@*CONCLUSION@#Bosentan improved exercise capacity, pulmonary function and cardiopulmonary hemodynamics among study participants. The drug is generally well-tolerated and effective. Bosentan is among the useful options for treatment of adult Filipino patients with PAH.

Distribuição do nervo fibular comum em fetos de equinos e descrição anatômica de pontos para bloqueio anestésico / Distribution of common peroneal nerve in equine fetuses and anatomical description of sites for anesthetic block

Analisou-se a distribuição do nervo fibular comum em 30 fetos de equinos, sem raça definida, provenientes do acervo do Laboratório de Anatomia Animal da Faculdade de Medicina Veterinária da Universidade Federal de Uberlândia, que foram injetados e conservados em solução aquosa de formaldeído a 10%. Contatou-se que o referido nervo deriva do isquiático, divide-se em nervos fibulares superficial e profundo, distribuindo-se para os músculos extensores lateral e longo do dedo, fibular terceiro e tibial cranial. Traçando-se uma linha imaginária na região médio-lateral da tuberosidade do osso tíbia, o nervo fibular comum pode ser bloqueado em sua parte proximal, no terço caudal, entre o tendão de inserção do músculo bíceps femoral e a face lateral do músculo gastrocnêmio lateral (terço médio); e o nervo fibular profundo, na parte proximal da tíbia, crânio-distalmente ao fibular comum. O bloqueio do nervo fibular superficial pode ser realizado em duas regiões da tíbia: na proximal, considerando-se a linha imaginária, distalmente ao ponto citado para o fibular comum e caudalmente ao descrito para o fibular profundo; e na distal, na face lateral da articulação tíbio-társica, entre os tendões de inserção dos músculos extensores lateral e longo do dedo.

The distribution of the nervus fibularis communis was analyzed in 30 equine fetuses, mongrel, from the collection of the Animal Anatomy Laboratory at the School of Veterinary Medicine of Universidade Federal de Uberlândia, which were injected and stored in an aqueous solution of 10% formaldehyde. It was found that this nerve emerges from the ischiadicus, divides itself into nervus fibularis profundus and nervus fibularis superficialis distributing to the musculi extensor digitorum lateralis, extensor digitorum longus, fibularis tertius, and tibialis cranialis. Drawing an imaginary line in the medial-lateral region of the tuberositatis tibia, the nervus fibularis communis may be blocked in its proximal portion, in the caudal third, between the tendon of insertion of the biceps femoris and the lateral side of the musculus gastrocnemius (medium third); and the nervus fibularis profundus may be blocked in the proximal tibia, cranio-distally to the nervus fibularis communis. The block of nervus fibularis profundus may be performed in two regions of the tibia: proximal, considering the imaginary line, distal to the site referred to the nervus fibularis communis, and caudal to that described for the nervus fibularis profundus; and distal, on the lateral side of the tibiotarsal joint, between the tendons of insertion of the musculi extensor digitorum lateralis and extensor digitorum longus.

Urethroplasty using a bovine pericardium graft: an experimental study using normal urethras from dogs

The use of bovine pericardium as a urethral patch to substitute a ventral segment of canine urethras was studied. Healing, epithelial growth, urethral permeability, fistulas, and calcification were analyzed. Thirty male mongrel dogs of medium and large size underwent resection of a ventral segment of the medial urethra measuring 2.0 x 0.5 cm, which was replaced with a bovine pericardium graft, treated with buffered glutaraldehyde and preserved in formaldehyde. Two running sutures of polygalactin 5-0 were applied, one on each side of the patch. The corpus spongiosum was closed with uninterrupted suture and the skin with interrupted suture of polygalactin 5-0. Six months later, the animals were examined and sacrificed under anesthesia. Retrograde urethrograms showed that the urethral healing was complete in six of the 30 animals, without stenosis, fistulas or dilations. Microscopic examination showed complete epithelization of these six urethras. The remaining 24 animals presented urethrocutaneous fistulas without stenosis, demonstrated by urethral catheterism using a 10-Fr plastic catheter. These data show that a successful urethral reconstruction of the penile urethra was possible in only 20 percent of the operated animals. Infection and leakage may be the cause of the urethrocutaneous fistulas present in 80 percent of cases. Further studies are necessary to determine whether such fistulas are avoidable. If they are, the bovine pericardium may well be an option in the treatment of urethral lesions in dogs.

Absorcion de la lactosa en parasitosis del intestino. / Lactose absorption in parasitic intestinal diseases

Con el proposito de conocer la prevalencia de hipolactasa en ninos mexicanos y la posible participacion que los parasitos intestinales pudieran tener en la deficiente absorcion de la lactosa, se llevo a cabo una investigacion en 101 escolares, empleando para ello la prueba del hidrogeno espirado. Como grupo de contraste se estudiaron con el mismo procedimiento un grupo de 12 ninos seleccionados bajo criterios estrictos. Los resultados mostraron una elevada prevalencia de hipolactasa; 69,3% de los escolares eliminaron el hidrogeno a una concentracion mayor de 20 ppm, despues de ofrecerles 250 milimetros de leche integra. En los escolares parasitados se encontraron las cifras mas altas de hidrogeno espirado; una vez erradicadas las parasitosis, se cancelaron las diferencias con respecto a los ninos no parasitados. Tambien hubo divergencias segun que los infantes albergan los parasitos en el intestino delgado o en el colon. Los ninos parasitados en el intestino delgado eliminaron una mayor concentracion de hidrogeno; los hallazgos permiten afirmar que la presencia de parasitos en esta porcion del intestino, interfiere con la absorcion de la lactosa contenida en 250 ml de leche

Aplicacion postplacenta de cinco tipos diferentes de dispositivos intrauterinos. / Post-placental insertion of five different types of intrauterine devices

Se analizan los resultados obtenidos en 1020 casos de aplicacion, inmediatamente despues del nacimiento de la placenta, de cinco tipos diferentes de dispositivos intrauterinos. En 101 casos se utilizo T Cu 220 C, en 407 Asa de Lippes, en 180 T Cu 200, en 196 Progestasert y en 136 Multiload 250. La aplicacion se hizo mediante tres tecnicas: a) manual, b) con pinza de Forester y c) con un aplicador en experimentacion. Cuando se utilizo el aplicador se observo mayor tasa de expulsiones y por tanto de embarazos. Las tasas de expulsiones y embarazos fueron mayores con el Progestasert. Con la Teu 220 C se observo el menor numero de expulsiones y de embarazos, asi como la mayor continuidad de uso.Los retiros por causas medicas fueron semejantes para todos los dispositivos intrauterinos
