Anàlisi de l’eficiència del servei de taxi a Barcelona. Propostes de millora

L'objectiu que s'aborda en aquesta Tesina és analitzar la situació del taxi a l'AMB i proposar mesures encaminades a millorar-ne l'eficiència. Aquesta optimització del servei del taxi ha donat peu a nombrosos estudis arreu del món en què es proposaven diferents models de predicció de la demanda en funció de la tarifa imposada i de la mida de la flota, entre d‟altres paràmetres. El document presentat, però, difereix d'aquesta tendència de la teoria clàssica

Gustatory function of sensilla chaetica on the labial palps and antennae of three tortricid moths (Lepidoptera: Tortricidae)

In adult Lepidoptera the labial palps are best known for their role in CO2 detection, but they can also bear sensilla chaetica which function is unknown. The number and distribution of sensilla chaetica in labial palps was studied using a bright field microscope. To determine if these sensilla have a gustatory function, we performed single sensillum electrophysiology recordings from palp and antennal sensilla of adult moths of Cydia pomonella (L.), Grapholita molesta (Busck) and Lobesia botrana (Denis and Shieffermüller). Each sensillum was stimulated with 3 doses of one of four test stimulus (sucrose, fructose, KCl and NaCl). Overall, responses (spikes/s−1) increased with dose, and were higher in the palps than in the antennae, and higher to sugars than to salts. With sugars the response increased with concentration in the palp but not in the antenna. With salts there was a drop in response at the intermediate concentration. The number and position of sensilla chaetica on labial palps was variable among individuals. Sensilla were located in the most exposed areas of the palp. Differences in sensilla distribution were detected between species. Such differences among species and between palps and antenna suggest that taste sensilla on the palps have an unforeseen role in adaptation.CA was supported by a Ph.D. fellowship BES-2017-081131 from the Ministerio de Economía, Industria y Competitividad (MINECO, Spain) joint financing by the European Social Fund.

Different population phenologies of Grapholita molesta (Busck) in two hosts and two nearby regions in the NE of Spain

Grapholita molesta is an important pest of stone and pome fruits. In commercial orchards, integrated pest management programs use pheromone traps to monitor the population dynamics of G. molesta and adjust treatments. Phenology models can be used to forecast the population phenology of pests and to help optimise the time point at which to spray the orchards with insecticides. In the present study, the adult population phenologies of G. molesta in two provinces of north-east Spain were studied, as well as their fit to the phenology model most used in both provinces. Weekly captures of adults in pheromone traps through the season were recorded over 5 y in a large number of commercial orchards, and these data were used to determine the number of generations of G. molesta in each province. The results show significant differences between provinces in the generation time, being 97 degree days (DD) shorter in the Lleida province than in the Girona province. In Girona province, four generations were registered, while five were detected in Lleida. As a result of the differences found, the phenology model was not able to predict precisely the population dynamics in the Girona province

Simultaneous bilateral dual mobility total hip arthroplasty dislocation in a patient with hepatic encephalopathy: A case report

Luxació; Mobilitat dual; Encefalopatia hepàticaDislocación; Movilidad dual; Encefalopatía hepáticaDislocation; Dual mobility; Hepatic encephalopathyIntroduction and importance Dislocation is a severe complication after total hip arthroplasty (THA). It is one of the most common reasons for failure and revision surgery. This is the first case of a documented simultaneous bilateral dual mobility (DM) THA dislocation. Case presentation A forty-nine-year-old man presented with bilateral hip pain, immobility and deformity. X-ray images demonstrated simultaneous bilateral posterior THA dislocation. Previously, the patient had presented atraumatic dislocations recurrently. When he was thoroughly re-interrogated, he complained of uncontrolled and generalized muscle contractions, which were compatible with myoclonus due to hepatic encephalopathy (HE). Multidisciplinary treatment was performed satisfactorily to control myoclonus symptomatology and to prevent dislocation. Clinical discussion Patient’s most important risk factor was a neuromuscular disorder, which we initially gave little notice and undervalued. HE is a serious but reversible syndrome, observed in patients with liver dysfunction. It leads to a wide spectrum of neuropsychiatric abnormalities. Management is based on prevention of episodes, avoiding the underlying triggers. Due to the high risk for dislocation of our patient, we decided to use DM cups bilaterally. This system has demonstrated lower rates of dislocation. Conclusion This case report reminds us that a careful evaluation through meticulous history and physical examination are mandatory when faced with recurrent instability. Furthermore, prevention of dislocation is vastly preferable to treating this challenging complication. High-risk patients should be identified, and appropriate surgical approach, technique and implants have to be collectively used to reach a strategy that mitigates and ideally prevents dislocation

Septic Arthritis and Multifocal Osteomyelitis Caused by Capnocytophaga Canimorsus: A Case Report

Capnocytophaga; Osteomyelitis; Septic arthritisCapnocitofaga; Osteomielitis; Artritis sépticaCapnocytophaga; Osteomielitis; Artritis sèpticaMicrobiological diagnosis of chronic osteoarticular infections remains a major challenge, particularly when the clinical presentation is atypical and the pathogen is uncommon. In this unique case, Capnocytophaga canimorsus, a microorganism belonging to the oral microbiota of some domestic animals, caused septic arthritis and multifocal osteomyelitis in the long bone of a 43-year-old immunocompetent man. The patient was treated with two-stage surgery and local and systemic antibiotic therapy, and had a successful recovery. C. canimorsus should be considered as a possible etiological agent in patients with osteoarticular pathology and a history of exposure to domestic animals

Sequential repeated tibial tubercle osteotomy in a two-stage exchange strategy: a superior approach to treating a chronically infected knee arthroplasty?

Periprosthetic joint infection; Tibial tubercle osteotomy; Two-stage revision arthroplastyInfecció articular periprotèsica; Osteotomia del tubercle tibial; Artroplàstia de revisió en dues etapesInfección articular periprotésica; Osteotomía del tubérculo tibial; Artroplastia de revisión en dos tiemposPurpose Surgical approach can impact the reliability of the debridement after a chronic total knee periprosthetic joint infection (PJI), a factor of utmost importance to eradicate the infection. The most adequate knee surgical approach in cases of PJI is a matter of debate. The purpose of this study was to determine the influence of performing a tibial tubercle osteotomy (TTO) in a two-stage exchange protocol for knee PJI treatment. Methods Retrospective cohort study examining patients managed with two-stage arthroplasty due to chronic knee PJI (2010–2019). Performance and timing of the TTO were collected. Primary end-point was infection control with a minimum FU of 12 months and according to internationally accepted criteria. Correlation between TTO timing and reinfection rate was reviewed. Results Fifty-two cases were finally included. Overall success (average follow-up: 46.2 months) was 90.4%. Treatment success was significantly higher among cases addressed using TTO during the second stage (97.1% vs. 76.5%, p value 0.03). Only 4.8% of the patients relapsed after performing a sequential repeated TTO, that is, during both first and second stages, compared to 23.1% cases in which TTO was not done (p value 0.28). No complications were observed among patients in the TTO group with a significant decrease in soft tissue necrosis (p: 0.052). Conclusion Sequential repeated tibial tubercle osteotomy during a two-stage strategy is a reasonable option and offers high rates of infection control in complex cases of knee PJI with a low rate of complications.Open Access Funding provided by Universitat Autònoma de Barcelona
