Abstract	The management of femoral neck fractures remains controversial. Treatment options include a wide variety of internal fixation methods, unipolar or bipolar hemiarthroplasty or total hip replacement.We carried out a systematic review of the available literature to detect differences between cemented and cementless fixation of bipolar prostheses in treating femoral neck fractures in patients aged 60 years or older.Thirteen studies involving a total of 1561 bipolar hemiarthroplasties (770 cemented and 791 uncemented) were identified. Uncemented hemiarthroplasty was associated with significantly lower blood loss (p < 0.0001), shorter operative time (p < 0.0001), less infection (p = 0.03) and lower risk of heterotopic ossification (p = 0.007). On the other hand, patients with cemented hemiarthroplasty suffered significantly less postoperative thigh pain than those with cementless implantation (p < 0.00001).The existing evidence indicates that uncemented bipolar hemiarthroplasty offers shorter operative time, less blood loss, lower local complications and a similar rate of systemic complications and reoperations as compared to cemented implantation.

Abstract	New composites made of natural fiber polymers such as wasted date palm surface fiber (DPSF) and pineapple leaf fibers (PALFs) are developed in an attempt to lower the environmental impact worldwide and, at the same time, produce eco-friendly insulation materials. Composite samples of different compositions are obtained using wood adhesive as a binder. Seven samples are prepared: two for the loose natural polymers of PALF and DPSF, two for the composites bound by single materials of PALF and DPSF using wood adhesive as a binder, and three composites of both materials and the binder with different compositions. Sound absorption coefficients (SACs) are obtained for bound and hybrid composite samples for a wide range of frequencies. Flexural moment tests are determined for these composites. A thermogravimetric analysis test (TGA) and the moisture content are obtained for the natural polymers and composites. The results show that the average range of thermal conductivity coefficient is 0.042-0.06 W/(m K), 0.052-0.075 W/(m K), and 0.054-0.07 W/(m K) for the loose fiber polymers, bound composites, and hybrid composites, respectively. The bound composites of DPSF have a very good sound absorption coefficient (>0.5) for almost all frequencies greater than 300 Hz, followed by the hybrid composite ones for frequencies greater than 1000 Hz (SAC > 0.5). The loose fiber polymers of PALF are thermally stable up to 218 °C. Most bound and hybrid composites have a good flexure modulus (6.47-64.16 MPa) and flexure stress (0.43-1.67 Mpa). The loose fiber polymers and bound and hybrid composites have a low moisture content below 4%. These characteristics of the newly developed sustainable and biodegradable fiber polymers and their composites are considered promising thermal insulation and sound absorption materials in replacing synthetic and petrochemical insulation materials in buildings and other engineering applications.

Abstract	Background: Alteration of patellar height is commonly encountered in total knee arthroplasty (TKA), and failure to address patella baja can result in suboptimal functional outcomes. It may therefore be prudent to evaluate pre-operative patellar height (PPH) and to seek risk factors for patella baja. Methods: Two hundred eighty-five patients who underwent TKA were included. Patient's age, gender, body mass index (BMI), and history of prior arthroscopy were recorded. PPH was measured using plateau-patella angle (PPA) as well as the Blackburn-Peel (BP), Caton-Deschamps (CD), and Insall-Salvati (IS) ratios. Results: The average patients' age was 71 years with a mean BMI of 30.45. There were 191 female and 94 male patients. One-fourth of the cases had at least one prior knee arthroscopy. Multivariate linear regression analysis identified gender and BMI as variables significantly affecting the IS ratio (p: < 0.05). Gender also had a significant correlation with PPA. Male patients were likely to have lower PPA (p: < 0.03). Though increasing age had a positive correlation with patellar height, this was not statistically significant. History of prior arthroscopy had no significant effect on any of the four PPH measurements. Conclusion: Lower patellar height is significantly correlated to male gender and high BMI. We suggest that obese male patients be screened for pre-operative patella baja. This can help in surgical planning and optimizing results in TKA.

Abstract	Salmonella osteomyelitis in immunocompetent adults is uncommon. It usually has a diaphyseal location or present as spondylitis. Metaphyseal affection is extremely rare. A 51-year-old male presented with refractory knee pain. Plain X-rays showed a rounded osteolytic lesion in the proximal tibia without marginal sclerosis. A minimal C-reactive protein elevation and a normal leucocytic count were present. Further imaging raised suspicion of malignancy so that a biopsy was done. After fenestering the lesion, 15-ml turbid fluid was evacuated. Microbiological examination showed Salmonella enteritidis. Repeated debridements were done and antibiotic therapy with ciprofloxacin was initiated. The cavity was then filled with synthetic bone graft leading to progressive healing. Although rare, Salmonella bone infection usually lacks the typical periosteal reaction and the laboratory evidence of infection of pyogenic osteomyelitis. It should therefore be considered in the differential diagnosis of osteolytic neoplastic lesions.

Abstract	Background: Despite evidence that effective family support improves health behaviour and outcomes, the nature of the correlation between congestive heart failure (CHF) outcome and caregiver contribution has not been well studied. Aim: This single centre pilot study aimed to determine epidemiological correlations between education level and hospital readmission and mortality rates of CHF patients in a nonwestern country population. Methods: The study was performed in King Abdullah Medical City, Makkah, Saudi Arabia from February 2015 to February 2016, and included 167 consecutive patients enrolled in a CHF management registry. Data on the education levels of patients and their caregivers were collected, and patient outcomes in high education level (HEL) and low education level (LEL) groups were compared. Results: Of 167 patients, 101 completed 12 months of follow-up. The mean age was 58 (13.4) years and 80% were men; 87% were Saudi nationals. The HEL group comprised 42 (42%) patients. There were no significant differences in the mortality (3 vs 2%) or readmission rate (18 vs 19%) between the LEL and HEL patients, and 29.6% of LEL patients had caregivers with an LEL. Conclusion: The education levels of CHF patients and caregivers were not correlated with readmission or mortality rates.

Abstract	Drought stress is one of the main problems for the rice crop, as it reduces the production and productivity of the grain yield significantly. In Egypt, many restrictions were made on the cultivation of rice due to its high-water demand. Producing promising drought-tolerant rice cultivars combined with high yielding is one of the main targets for rice breeders. A set of 22 highly diverse rice genotypes were evaluated under normal and drought conditions. Morphological, physiological, and yield traits were recorded on each genotype. Drought susceptibility index (DSI) was estimated for six yield traits to identify the most drought-tolerant rice genotypes. A high genetic variation was found among genotypes tested in the experiment. Under normal conditions, the highest phenotypic correlation was found between grain yield (GY) and sterility percentage (SP) (- 0.73), while it was among GY and chlorophyll content (CC) (0.82) under drought conditions. To identify quantitative trait loci (QTL) controlling yielding traits under drought and normal, a single marker analysis was performed between all yield traits under both conditions and a set of 106 simple sequence repeat (SSR) marker alleles. The genetic association analysis revealed 14 and 17 QTL under drought and normal conditions, respectively. The most drought-tolerant genotypes were selected based on phenotypic traits, the number of QTL in each selected genotype, and the level of genetic diversity existed among the genotypes. As a result, five genotypes (Giza 178, IET1444, GZ1368-S-5-4, Nahda, Giza 14) were identified as the most promising drought-tolerant rice genotypes. Eight QTL controlling drought tolerance were identified in Giza 178, Nahda, and GZ1368-S-5-4, while four QTL were found in IET1444. The number of different QTLs were estimated among the five selected genotypes. Giza 178 and GZ1368-S-5-4 shared the same QTLs. Seven different QTLs were found among Nahda, IET1444, GZ1368-S-5-4, and Giza 14. Combining information from phenotypic traits, genetic diversity analysis, and QTL analysis was very useful in identifying the true drought-tolerant rice genotypes that can be used for crossing in the future breeding program.

Abstract	Purpose: Unreamed nailing has gained acceptance in the treatment of diaphyseal long bone fractures, especially in cases with polytrauma or high-energy injuries. Its application in distal tibial fractures, however, remains controversial. Methods: In this study, 101 distal tibial fractures treated using closed unreamed nailing were reviewed after a mean follow-up of 32 months. There were 59 type A und 42 type B fractures. The most common fracture pattern was the A1 spiral fracture (n = 40) followed by the B2 wedge fracture (n = 18). Intra-articular extension was encountered in 14 cases. One-fourth of the patients (n = 24) had open injuries. Forty-seven patients had additional injuries, and nearly one-third of them were polytraumatised. Results: Union occurred after a mean time of 23.9 (range, 11-134) weeks. There were 13 cases of delayed union and seven non-unions; all healed eventually with additional surgery in only six fractures. Malunion was seen in 12 cases (five valgus, two varus and five external torsion), ten of which were associated with unplated fibular fractures. Three fractures (two open) were treated for deep infection. The most common complication seen was fatigue failure of the locking screws (27 cases). Conclusions: Unreamed nailing of distal tibial fractures is associated with a rather high rate of bone healing complications and locking screw failure. The decision for its use in the notoriously challenging fractures of this segment should be critically considered.
