A Modular In-Vehicle C-ITS Architecture for Sensor Data Collection, Vehicular Communications and Cloud Connectivity.

The growth of the automobile industry in recent decades and the overuse of personal vehicles have amplified problems directly related to road safety, such as the increase in traffic congestion and number of accidents, as well as the degradation of the quality of roads. At the same time, and with the contribution of climate change effects, dangerous weather events have become more common on road infrastructure. In this context, Cooperative Intelligent Transport Systems (C-ITS) and Internet of Things (IoT) solutions emerge to overcome the limitations of human and local sensory systems, through the collection and distribution of relevant data to Connected and Automated Vehicles (CAVs). In this paper, an intra- and inter-vehicle sensory data collection system is presented, starting with the acquisition of relevant data present on the Controller Area Network (CAN) bus, collected through the vehicle's On-Board-Diagnostics II (OBD-II) port, as well as on an on-board smartphone device and possibly other additional sensors. Short-range communication technologies, such as Bluetooth Low Energy (BLE), Wi-Fi, and ITS-G5, are employed in conjunction with long-range cellular networks for data dissemination and remote cloud monitoring. The results of the experimental tests allow the analysis of the road environment, as well as the notification in near real-time of adverse road conditions to drivers. The developed data collection system reveals itself as a potentially valuable tool for improving road safety and to iterate on the current Road Weather Models (RWMs).

Severe encephalopathy after ingestion of star fruit juice in a patient with chronic renal failure admitted to the intensive care unit.

Star fruit (Averrhoa carambola) is a popular tropical fruit that is usually consumed as fresh fruit or fruit juice. Consumption of star fruit by patients with chronic renal failure can lead to neurologic symptoms. The present report describes the clinical course, management, and outcome of a patient with chronic renal failure admitted to an intensive care unit after ingestion of star fruit juice 2 days before hospital admission. A case of nausea, vomiting, intractable hiccups, and severe encephalopathy along with mental confusion, disorientation, agitation, and seizures in a 53-year-old woman is presented. The patient's ventilatory pattern worsened, with development of dyspnea and tachypnea, which resulted in her transfer to an intensive care unit. Although hemodialysis was performed and the septic shock was adequately treated, the patient died on the fifth day after hospital admission. The susceptibility of patients with chronic renal failure to star fruit and the severity of intoxication are poorly known by intensivists. This case demonstrates that star fruit consumption should be considered as a cause of rapid deterioration in the renal function of patients with underlying chronic renal failure, potentially resulting in a fatal outcome.

Septic shock caused by Plesiomonas shigelloides in a patient with sickle beta-zero thalassemia.

Invasive infection and extraintestinal complications are rarely caused by Plesiomonas shigelloides, a waterborne bacterium belonging to the Vibrionaceae family. We report a case of a 16-year-old female patient with sickle beta-zero thalassemia who survived septic shock caused by P. shigelloides associated with secondary acute respiratory distress syndrome and disseminated intravascular coagulation. Treatment with a carbapenem was successful, and the patient recovered without any sequelae. The previous reports of P. shigelloides sepsis are cited, and possible pathogenic mechanisms are discussed.

Fulminant nonocclusive mesenteric ischemia just after hip arthroplasty.

Nonocclusive mesenteric ischemia (NOMI) is not a rare clinical entity in intensive medicine, and it can be a consequence of several clinical or surgical situations. This pathology results from reduced intestinal microvascular blood supply associated with an acute inflammatory process, culminating with bowel necrosis. This is a case on a female patient who developed immediate postsurgical NOMI following hip arthroplasty and died. Since diagnosis of this potentially fatal condition remains a dilemma, NOMI should always be considered an eventual postoperative complication in high-risk surgical patients such as elderly individuals with previous history of nicotine abuse, congestive heart failure, and essential hypertension. The present paper highlights the importance of early diagnosis and prompt adequate treatment of NOMI in subjects with diminished cardiac output and severe abdominal pain.

Effectiveness of oral rinse with chlorhexidine in preventing nosocomial respiratory tract infections among intensive care unit patients.

OBJECTIVE: To evaluate the effectiveness of the oral application of a 0.12% solution of chlorhexidine for prevention of respiratory tract infections among intensive care unit (ICU) patients. DESIGN: The study design was a double-blind, randomized, placebo-controlled trial. SETTING: The study was performed in an ICU in a tertiary care hospital at a public university. PATIENTS. Study participants comprised 194 patients admitted to the ICU with a prospective length of stay greater than 48 hours, randomized into 2 groups: those who received chlorhexidine (n = 98) and those who received a placebo (n = 96). INTERVENTION: Oral rinses with chlorhexidine or a placebo were performed 3 times a day throughout the duration of the patient's stay in the ICU. Clinical data were collected prospectively. RESULTS: Both groups displayed similar baseline clinical features. The overall incidence of respiratory tract infections (RR, 1.0 [95% confidence interval [CI], 0.63-1.60]) and the rates of ventilator-associated pneumonia per 1,000 ventilator-days were similar in both experimental and control groups (22.6 vs 22.3; P = .95). Respiratory tract infection-free survival time (7.8 vs 6.9 days; P = .61), duration of mechanical ventilation (11.1 vs 11.0 days; P = .61), and length of stay (9.7 vs 10.4 days; P = .67) did not differ between the chlorhexidine and placebo groups. However, patients in the chlorhexidine group exhibited a larger interval between ICU admission and onset of the first respiratory tract infection (11.3 vs 7.6 days; P = .05). The chances of surviving the ICU stay were similar (RR, 1.08 [95% CI, 0.72-1.63]). CONCLUSION: Oral application of a 0.12% solution of chlorhexidine does not prevent respiratory tract infections among ICU patients, although it may retard their onset.

Perforation of the right ventricle induced by pulmonary artery catheter at induction of anesthesia for the surgery for liver transplantation: a case report and reviewed of literature.

We report a case of a 45-year-old male patient diagnosed with liver cirrhosis by hepatitis C and alcohol, with a Child-Pugh score C and a model for end-stage liver disease (MELD) score of 27, and submitted to liver transplantation. The subject underwent insertion of the pulmonary artery catheter (PAC) in the right internal jugular vein, with technical difficulty concerning catheter advance. There was sudden hypotension, increase in central venous pressure (CVP), and decrease in SvO(2) 15 minutes after the PAC had been inserted, followed by cardiorespiratory arrest in pulseless electrical activity (PEA), which was promptly assisted with resuscitation. Pericardiocentesis was performed without success, so the individual was subjected to a subxiphoid pericardial window, which led to output of large amounts of blood as well as PEA reversal to sinus rhythm. Sternotomy was performed; rupture of the apex of the right ventricle (RV) was detected, and suture of the site was accomplished. After hemodynamic stabilization, the patient was transferred to the ICU, where he developed septic shock and, despite adequate therapy, died on the eighteenth day after ICU admission.

Tétano grave associado a choque séptico em uma paciente idosa internada em unidade de terapia intensiva / Tétanos grave asociado con choque séptico en una paciente anciana ingresada en la unidad de cuidados intensivos / Severe tetanus associated with septic shock in an elderly patient admitted to the intensive care unit

Nós relatamos um caso de tétano grave associado a choque séptico em uma paciente de 61 anos admitida na Unidade de Terapia Intensiva (UTI) após perfurar o pé direito. A paciente apresentou perda de força muscular, paresia em membro inferior direito e disfagia. A paciente evoluiu com espasmos musculares generalizados, dispnéia e insuficiência respiratória. O espasmo intenso levou ao uso prolongado de ventilação mecânica invasiva, sedação e bloqueador neuromuscular. A evolução favorável deste caso está provavelmente relacionada aos avanços na gestão de UTI e uma equipe médica e de enfermagem bem treinadas.

We report a case of severe tetanus associated with septic shock in a 61-year-old female admitted to the Intensive Care Unit (ICU) after perforating injury in the right foot. The patient presented with loss of muscle strength, paresis in the right lower limb and dysphagia. The patient’s conditions worsened, progressing to generalized muscle spasms, dyspnea, and respiratory failure. Intense spasm made the prolonged use of invasive mechanical ventilation, sedation, and neuromuscular blockers necessary. The favorable outcome in the present case is probably related to advances in ICU management and well-trained medical and nursing staff.
