Poly(lactic acid) (PLA) was melt mixed in a laboratory extruder with poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate) (PBS) in the presence of polypropylene glycol di glycidyl ether (EJ400) that acted as both plasticizer and compatibilizer. The process was then scaled up in a semi-industrial extruder preparing pellets having different content of a nucleating agent (LAK). All of the formulations could be processed by blowing extrusion and the obtained films showed mechanical properties dependent on the LAK content...

Purpose: Pain sensitivity has been identified as a factor that affects how individuals answer dry eye questionnaires, but it is unknown how it affects ocular discomfort. This study used the time that individuals could refrain from blinking as an indicator of ocular discomfort and set out to determine whether it was related to pain sensitivity, while adjusting for ocular surface conditions. Methods: Subjects first completed the Pain Sensitivity Questionnaire to quantify pain sensitivity levels...

Cartilage degeneration are hallmarks of wear, tear, mechanical and inflammatory damage of the joint cartilage. Tissue degradation as well as compromising the integrity and function of the organ, produces different intermediates, directly able to stimulate further inflammatory effect, therefore, amplifying the inflammation response. Biglycan is a soluble component of the extracellular matrix that is released during tissue injury. It has been reported that released biglycan is an endogenous ligand for TLR-2/4 in some cell type...

BACKGROUND: Rotator cuff tears are believed to coexist with cervical spine lesions. In cases of preexisting neuropathy, such as cervical spine lesions, fatty degeneration has likely already occurred due to the neuropathy. In these cases, rotator cuff tear is thought to occur easily because of preexisting extensive fatty degeneration and degeneration of the tendons due to neuropathy. This study aimed to evaluate the effects of paralysis due to neuropathy proximal to the suprascapular nerve on the supraspinatus and infraspinatus tendons using a rat model of brachial plexus paralysis...

Management of proximal and distal biceps tendon pathology is evolving. The long head of the biceps tendon, if inflamed, may be a pain-producing structure. In appropriately indicated patients, a symptomatic long head of the biceps tendon can be surgically managed via tenotomy, tenodesis, and/or superior labrum anterior to posterior repair. In some patients, primary superior labrum anterior to posterior pathology can be managed via biceps tenodesis. Determining which procedure is most appropriate and which technique and implant are preferred for a given patient with biceps tendon pathology is controversial...

BACKGROUND: Subscapularis (SSC) tendon tears are a challenging problem because they can significantly alter shoulder mechanics and function. Tendon retraction and advanced fatty degeneration associated with a chronic tear may make it irreparable. Tendon transfers options for such tears are viable, but results in the setting of associated glenohumeral instability are inconsistent. With the potential to recreate the SSC line of pull, the teres major (TM) may be a viable option for transfer...

Dry eye disease (DED) is a common condition with signs and symptoms that vary depending on a wide range of environmental factors to which people are exposed in their daily lives. Factors such as variable temperature, airflow velocity, relative humidity, seasonality, and pollutants can alter the rate of tear film evaporation, improving or exacerbating symptoms of DED. Results from currently available clinical tests do not always correlate well with patient-reported symptoms, and the continually changing environment and variability in DED symptoms present challenges for the design and conduct of clinical trials...

INTRODUCTION: Lateral trochanteric pain (LTP) complicates up to 17% of cases of total hip arthroplasty (THA). Studies have refuted underlying trochanteric bursitis. Restoration of the femoral offset and reproduction of the natural femoral centre of rotation are important in successful arthroplasty. LTP is believed to be associated with their alteration. AIM: The aim of our study was to evaluate the effect of femoral offset and centre of rotation on the incidence of LTP post-THA...

Lucie Juliot
Patients with psychosis speak of an uneasy relationship with their body. Between feelings of too little and too much, for them it is a matter of trying to suture an image which is not always unified, a body which they are not always sure they have. The attentive clinician will attempt to support the solutions of each psychotic patient to maintain their body, beyond the death drive which pushes them to tear it apart.

An impaired ocular surface adversely affects preoperative planning for cataract surgery, including intraocular lens (IOL) calculations, toric IOL axis and magnitude estimates, keratometry, and topography measurements. It also increases surgical difficulty. We performed a review to evaluate the connection between cataract surgery and dry eye and to determine the best management for these patients. Of the 16 papers included in this review, 6 were randomized controlled trials. Cataract surgery was shown to worsen ocular parameters and aggravate dry-eye disease...

BACKGROUND: Triple A syndrome (or Allgrove syndrome) is a rare autosomal recessive disorder characterized by alacrima, achalasia, adrenal insufficiency and autonomic/neurological abnormalities. The majority of cases are caused by mutations in the AAAS gene located on chromosome 12q13. However, the clinical picture as well as genetic testing may be complex since symptomatology is variable and mutations cannot be identified in all clinically diagnosed patients. We present two unrelated patients with triple-A syndrome illustrating the importance of alacrima as an early clinical sign...

Blood glucose concentration is a key indicator of patients' health, particularly for symptoms associated with diabetes mellitus. Because of the large number of diabetic patients, many approaches for glucose measurement have been studied to enable continuous and accurate glucose level monitoring. Among them, electrochemical analysis is prominent because it is simple and quantitative. This technology has been incorporated into commercialized and research-level devices from simple test strips to wearable devices and implantable systems...
