Ageing is a process of declining bodily function and a major risk factor of chronic diseases. The declining bodily function in ageing can cause loss of proteostasis (protein homeostasis), which is a balance between protein synthesis, folding, modification and degradation. For the elderly, adequate protein intake is necessary to prevent sarcopenia, frailty, fracture and osteoporosis as well as reduced resistance to infection. However, increasing the protein intake can enhance the risk of oxidized protein formation, loss of proteostasis and degenerative disorder occurrence. On the other hand, several studies show that protein restriction would increase longevity. The aim of this review was to explain the importance of determining the right amount and composition of protein intake for the elderly. Oxidative stress and molecular mechanism of proteostasis loss in ageing cells as well as its suppression pathway by protein restriction are discussed in this review. © 2021 Kirana A. N. et al. |

Parameatal glans cyst is unusual and only a few cases reported until currently. We presented a four-year-old boy with dysuria and inappropriate appearance of parameatal glans cyst. The cystic mass was slow-growing and was present since birth. Complete surgical excision was performed to prevent recurrencies and to achieve good cosmesis. © 2021 The Authors |

Urethral caruncle is a rare condition primarily affecting elderly. Sometimes, it resembles urethral prolapse or malignancies. It can even cause outflow obstruction or urinary retention. A case of 83-years-old woman with urinary retention since a week prior was presented. Physical examination revealed a bulging mass originating from posterior lip of external urethral meatus. Due to the size, it caused outflow obstruction. The whole mass was excised. Histology examination reported the mass as urethral caruncle. Urethral caruncle is a common problem in elderly which rarely cause outflow obstruction. A thorough examination is required to distinguish it from malignancies and other disorders. © 2021 |

Renal ectopia with stone is a rare case with no specific reported incidence rate. The treatment of kidney stone in ectopic kidneys poses a challenge to urologists. A 48-year-old male presenting with colicky pain on the right flank since one year ago. CT urography revealed an right-crossed renal ectopia and hyperdense lesions (25 × 20 mm and 10 × 10 mm) in the ureteropelvic junction of the right kidney. Under general anesthesia, we performed open pyelolithotomy for the patient and removed two stones completely. Open surgery could be the choice for patients with complex stone burden and associated renal anomalies such as ectopic kidney. © 2020 |

Spinal deformity concomitantly with large renal stone has become a challenges for urologist since it needs different approach in performing percutaneous procedures. This case report highlight our success experience in treating a 53-years old female patients with severe degree of kyphosis and staghorn stone using supine PCNL. She underwent right PCNL and right Double-J stent insertion anterograde after stone were released. The duration of surgery was 2 hours and 45 minutes with no intra and post-operative complication reported. Supine position can be safely chosen if prone cannot be placed in complex situation such as staghorn stone in severe kyphosis patients. © 2020 The Authors |

Spinal cord injury often results in neurogenic bladder condition and eventually lead to an end-stage renal disease requiring kidney transplantation. However, transplantation in abnormal bladder carries special considerations. We report a case of an adult male with end-stage chronic kidney disease and small bladder capacity after having spinal cord injury. The evaluation of videourodynamic showed reduced compliance and detrusor overactivity during filling phase. Kidney transplantation and vesicostomy was performed. Eighteen months follow-up after surgery showed that kidney function could be maintained. The prevention of increasing bladder pressure and UTI should be monitored to prevent the damage of the graft kidney. © 2020 The Author(s) |

SARS-CoV-2 and its variants caused the COVID-19 pandemic. Vaccines that target conserved regions of SARS-CoV-2 and stimulate protective T-cell responses are important for reducing symptoms and limiting the infection. Seven cytotoxic (CTL) and five helper T-cells (HTL) epitopes from ORF1ab were identified using NetCTLpan and NetMHCIIpan algorithms, respectively. These epitopes were generated from ORF1ab regions that are evolutionary stable as reflected by zero Shannon’s entropy and are presented by 56 human leukocyte antigen (HLA) Class I and 22 HLA Class II, ensuring good coverage for the Indonesian and world population. Having fulfilled other criteria such as immunogenicity, IFNγ inducing ability, and non-homology to human and microbiome peptides, the epitopes were assembled into a vaccine construct (VC) together with β-defensin as adjuvant and appropriate linkers. The VC was shown to have good physicochemical characteristics and capability of inducing CTL as well as HTL responses, which stem from the engagement of the vaccine with toll-like receptor 4 (TLR4) as revealed by docking simulations. The most promiscuous peptide899WSMATYYLF907 was shown via docking simulation to interact well with HLA-A*24:07, the most predominant allele in Indonesia. The data presented here will contribute to the in vitro study of T-cell epitope mapping and vaccine design in Indonesia. © 2021 by the authors. Licensee MDPI, Basel, Switzerland. |

With a limited number of vaccines and healthcare capacity shortages, particularly in low-and middle-income countries, vaccination programs should seek the most efficient strategy to reduce the negative impact of the COVID-19 pandemics. This study aims at assessing several scenarios of delivering the vaccine to people in Indonesia. We develop a model for several scenarios of delivering vaccines: without vaccination, fair distribution, and targeted distribution to five and eight districts with the highest COVID-19 incidence in West Java, one of the most COVID-19-affected regions in Indonesia. We calculate the needs of vaccines and healthcare staff for the program, then simulate the model for the initial 4-month and one-year scenarios. A one-year vaccination program would require 232,000 inoculations per day by 4833 vaccinators. Targeted vaccine allocation based on the burden of COVID-19 cases could benefit the COVID-19 vaccination program by lowering at least 5000 active cases. The benefits would increase by improving the number of vaccines and healthcare staff. Amidst lacking available vaccines, targeted vaccine allocation based on the burden of COVID-19 cases could increase the benefit of the COVID-19 vaccination program but still requires progressive efforts to improve healthcare capacity and vaccine availability for optimal protection for people. © 2021 by the authors.

Background and Aim: Pediculus humanus capitis, the human head louse, remains a global health problem. This study evaluated the resistance of head lice to permethrin and 6-paradol mediated by in vitro detoxification enzyme activity experiments and to describe physical changes in the lice using scanning electron microscopy (SEM). Materials and Methods: The adult stages of P. h. capitis were collected from patients exposed to 1% permethrin and three different concentrations of 6-paradol (0.00005%, 0.0001%, and 0.00015%) using a filter paper diffusion bioassay. Healthy P. h. capitis adults served as the control. The in vitro bioassays were conducted after 10, 20, 30, and 60 min of exposure. The activities of acetylcholinesterase (AChE), glutathione S-transferase (GST), and oxidase were analyzed. Physical changes in the lice were analyzed using SEM. Results: Permethrin and 6-paradol exhibited low toxicity against the lice. At 60 min, 1% permethrin had killed 36.7% of the lice present, while 6-paradol had killed 66.7-86.7%. Permethrin induced significantly elevated AChE, GST, and oxidase activity; 6-paradol also caused significantly elevated AChE, GST, and oxidase activity. Permethrin did not cause any ultrastructural morphological changes on the lice, while 6-paradol severely damaged the head, thorax, respiratory spiracles, and abdomen of the dead lice. Conclusion: This in vitro experimental of P. h. capitis is the first study to report P. h. capitis in East Jakarta shows complete resistance to permethrin and 6-paradol, and to describe the associated increase in AChE, GST, and oxidase activity. It was observed that 6-paradol severely damaged the head, thorax, respiratory spiracles, and abdomen of the dead lice. © 2021 Veterinary World. All rights reserved. |
