First-principles thermodynamics enables the description of the surface chemistry of inorganic materials as a function of temperature and partial pressures of atmospheric gases, providing a framework to connect atomistic simulations with macroscopic materials properties. Here we re-examine the surface chemistry of LiFePO4 (LFP), a widely studied material for use as the cathode in Li-ion batteries. Our results reveal that at room temperature and under standard pressures the LFP (010) surface is covered with water. At elevated temperatures and reduced H2 partial pressure, one water molecule loses a hydrogen atom and the preferred binding moieties are OH and H2O; while further reducing the H2O partial pressure results in the desorption of water leaving only the OH behind. This work also shines new light on the configuration, and resulting electronic properties, of the LFP (010) surface when molecular oxygen (O2) is adsorbed. The molecular adsorbates are also shown to have an impact on the LFP surface potentials and magnetic properties. These simulations provide an enhanced picture of the LFP surface chemistry and the potential impact of these adsorbates on understanding the characteristics of LFP in different materials applications.While sporadic Creutzfeldt-Jakob disease (sCJD) typically presents with neurological symptoms such as cognitive impairment, ataxia, and myoclonus, its clinical manifestations can be diverse. We report about a 70-year-old woman with sCJD who was misdiagnosed with recurrent stroke. She initially showed hemiplegia and high-intensity signals on brain diffusion-weighted magnetic resonance imaging (DWI), which corresponded to the symptoms of a stroke. She was diagnosed with recurrent stroke as her muscle weakness showed stepwise deterioration, with the appearance of additional high-intensity signals on brain DWI. Several days later, she developed Broca's aphasia, cognitive impairment, and myoclonus in the right upper and left lower extremities. Brain DWI showed high-intensity signals in the cortex, caudate nucleus, and putamen. Therefore, sCJD was suspected; she subsequently underwent further evaluation and was diagnosed with sCJD. The findings of this case indicate that sCJD can have a clinical course similar to that of recurrent stroke.
Data on the functional outcomes of hip fracture patients in Sri Lanka are limited. As this information is required for the design of long-term care plans, we assessed the physical activities (activities of daily living [ADL]) and quality of life (QoL) of hip fracture survivors in Sri Lanka.

A group of 180 consecutive patients with incident hip fractures admitted to a tertiary care center in Southern Sri Lanka were followed up for 12 months. The Sinhala versions of the Barthel Index, 36-Item Short-Form Survey, and Mini-Mental State Examination were used to assess ADL, QoL, and mental status, respectively.

Of the 180 patients (149 women), 107 underwent surgery. An initial sharp decline and partial recovery of ADL and QoL were observed among patients with hip fractures. Furthermore, patients who underwent surgical treatment showed faster recovery of ADL and QoL than did patients who were managed conservatively. Similarly, patients who did not have complications during the hospital stay showed faster recovery had a faster recovery than did patients who did not undergo surgery; similarly, patients without complications also had a faster recovery than did those with complications.
The Self-care Ability Scale for the Elderly (SASE) is a frequently used scale that was created in Sweden according to Orem's self-care deficit theory and later modified according to Pörn's theory of environment and purpose. This study translated and cross-culturally adapted the Turkish version of the SASE (T-SASE) and demonstrated its psychometric properties, including its reliability and construct validity.

This study recruited a total of 122 participants and applied international guidelines for the translation and adaptation of the scale. The test-retest reliability of the SASE was calculated at 1-week intervals. Internal consistency was analyzed using Cronbach's alpha. For construct validity, we compared the T-SASE to the Nottingham Extended Activities of Daily Living Scale (NEADLS) and the Exercise of Self-Care Agency Scale (ESCAS).

The mean age of the participants was 68.6±5.7 years. The test-retest reliability of the T-SASE was excellent (intraclass correlation coefficient=0.914; 95% confidence in Cronbach's alpha scores for the individual items, ranging from 0.901 to 0.915. L(+)-Monosodium glutamate monohydrate datasheet The items were also highly consistent with each other (Cronbach's α>0.80). The construct validity of the T-SASE was acceptable (0.35<r<0.50) in a convergent manner. The T-SASE was also strongly correlated with the NEADLS and ESCAS (r1=0.405, r2=0.437, p<0.01). Conclusions The T-SASE was a reliable and valid tool for assessing the self-care ability of community-dwelling older adults. Owing to its multidimensional structure, the T-SASE is an essential tool for evaluating self-care in older adults.The increasing survival rate after discharge from the intensive care unit (ICU) has revealed long-term impairments in the cognitive, psychiatric, and physical domains among survivors. However, clinicians often fail to recognize this post-ICU syndrome (PICS) and its debilitating effects on family members (PICS-F). This study describes two cases of PICS to illustrate the different impairments that may occur in ICU survivors. The PICS risk factors for each domain and the interactions among risk factors are also described. In terms of diagnostic evaluation, limited evidence-based or validated tools are available to assist with screening for PICS. Clinicians should be aware to monitor for its symptoms on the basis of cognitive, psychiatric, and physical domains. The Montreal Cognitive Assessment is recommended to screen for cognition, as it has a high sensitivity and can evaluate executive function. Mood disorders should also be screened. For mobile patients, a 6-minute walk test should be performed. PICS can be prevented by applying the ABCDEF bundle ABCDEF bundle in ICU described in this paper. Finally, the family members of patients in the ICU should be involved in patient care and a tactful communication approach is required to reduce the risk of PICS-F.
