Mexican immigrants are affected by Chagas disease (CD) in California. It is through the representation of Chagas as a rare disease that participants make sense of the disease. A positive diagnosis has meant the disruption of patients' sense of normality and self-image, as well as their memories of homeland both reproducing and challenging hegemonic and stigmatized ideas of the disease associated with rurality and poverty. Access to treatment and medical care was the major coping mechanism. Health programs on CD should consider the emotional and social impact of the disease on people's self-perceptions to develop better medical care and prevention.Obesity and its related co-morbidities, namely type 2 diabetes (T2D), pose a significant global public health problem. Insulin resistance (IR) in muscle and liver is the core pathophysiologic defect that underlies obesity preceding and predicting the onset of T2D in susceptible humans. There is a broad population with IR that has no indication for prescription of medications, who still need medical consultation and specific advice in this respect. This prevalent need can be achieved by appropriate diet, exercise, and other behavioral therapies for lifestyle interventions. Despite a well-recognized role of IR in the progression to metabolic diseases, no specific nutritional recommendations exist to manage this condition, to the best of our knowledge. An international panel of experts reviewed and critically appraised the updated literature published about this topic. This review primarily examines the evidence for areas of consensus and ongoing uncertainty or controversy about diet and exercise approaches for IR. The aim of this article is to present the most common IR states, namely obesity and Polycystic Ovary Syndrome (PCOS), and provide nutritional advice to manage IR, hyperinsulinemia, and reactive hypoglycemia. These nutritional guidelines could prevent progression or worsening of IR with resultant beta-cell failure and, as a result, T2D.While transdiagnostic factors are important domains in clinical assessment and treatment, there is little research to link such constructs to widely accepted and utilized broadband assessments such as the Minnesota Multiphasic Personality Inventory, 2nd edition - Restructured Form (MMPI-2-RF). A handful of studies suggest the ability of the MMPI-2-RF scales to capture variance in transdiagnostic constructs; however, this literature relies solely on self-report criterion measures, despite evidence that self-report and behaviorally-indexed correlates of psychopathology may measure varied aspects of the intended construct and can often yield differing results. The current study investigated MMPI-2-RF scales' ability to assess two widely examined transdiagnostic constructs, distress tolerance and pain perception, across both self-report and behavioral indicators. The sample included 115 undergraduate students who completed a valid MMPI-2-RF and multimethod measures of pain perception and distress tolerance. The results aligned with prior research in areas of internalizing symptoms, psychopathy, and suicide risk factors in self-report, but not behaviorally-based, assessment. Implications of this inconsistency, the association between clinical assessment and transdiagnostic constructs, and the heterogeneity of the distress tolerance and pain perception constructs are discussed.
The effect of high tibial osteotomy (HTO) on the stress distribution across the knee joint is not completely understood. Subchondral bone density is considered to reflect the pattern of stress distribution across a joint surface.

To assess the distribution of subchondral bone density across the proximal tibia in nonarthritic knees and in the knees of patients with osteoarthritis (OA) before and after HTO.

Cohort study; Level of evidence, 3.

We retrospectively collected radiological and computed tomography data from 16 patients without OA (control group) and 17 patients with OA. Data from the OA group were collected before and 1.5 years after HTO. Subchondral bone density of the proximal tibia was assessed with computed tomography-osteoabsorptiometry. The locations and percentages represented by high-density areas (HDAs) on the articular surface were quantitatively analyzed.

The ratio of the HDA of the medial compartment to the total HDA (medial ratio) was significantly higher in the preoperative OA bial articular surface toward the lateral compartment. In contrast, the HDA of the most lateral region of the medial compartment increased after HTO. This change in subchondral bone density may result from the change in stress distribution.As advances in prehospital and early hospital care improve survival of the head-injured patient, radiologists are increasingly charged with understanding the myriad skull base fracture management implications conferred by CT. Successfully parlaying knowledge of skull base anatomy and fracture patterns into precise actionable clinical recommendations is a challenging task. The authors aim to provide a pragmatic overview of CT for skull base fractures within the broader context of diagnostic and treatment planning algorithms. Laterobasal, frontobasal, and posterior basal fracture patterns are emphasized. CT often plays a complementary, supportive, or confirmatory role in management of skull base fractures in conjunction with results of physical examination, laboratory testing, and neurosensory evaluation. CT provides prognostic information about short- and long-term risk of cerebrospinal fluid (CSF) leak, encephalocele, meningitis, facial nerve paralysis, hearing and vision loss, cholesteatoma, vascular injuries, and various cranial nerve palsies and syndromes. The radiologist should leverage understanding of specific strengths and limitations of CT to anticipate next steps in the skull base fracture management plan. Additional imaging is warranted to clarify ambiguity (particularly for potential sources of CSF leak); in other cases, clinical and CT criteria alone are sufficient to determine the need for intervention and the choice of surgical approach. The radiologist should be able to envision stepping into a multidisciplinary planning discussion and engaging neurotologists, neuro-ophthalmologists, neurosurgeons, neurointerventionalists, and facial reconstructive surgeons to help synthesize an optimal management plan after reviewing the skull base CT findings at hand.
